Cabinet (CAB) Maker: \windows\system32\makecab.exe; diantz.exe

Cabinet file (.cab) compression utility.

To open

Command Prompt makecab

Usage

makecab [/v[n]] [/d var=value] [/l dir] source [destination]
makecab [/v[n]] [/d var=value] /f directive_file

Description

A cabinet file is a compressed archive commonly used to package application installation files. Cabinets are similar to .zip files, although they have added features such as a rudimentary script system intended to install and register application components.

There are two ways to use the Cabinet Maker. First, you can compress one or more files directly, like this:

makecab \windows\greenstone.bmp greenstone.cab

The preceding code compresses the file greenstone.bmp into the greenstone.cab archive. The new cabinet file, greenstone.cab, is created automatically in the current directory; if it already exists, it is replaced with the new archive. Unfortunately, wildcards (*.*) aren't allowed in the source, so you can specify only one file at a time. This is where the second usage of the Cabinet Maker comes in: instead of specifying options and files directly, a single plain-text file, called a directive file (.ddf), is used. The simplest directive file lists all the files to include. A line beginning with a semicolon is treated as a comment.

Assuming the lines:

;Example directive file
c:\windows\greenstone.bmp
c:\windows\rhododendron.bmp

are saved into a file called test.ddf, the makecab command would then look like this:

makecab /f test.ddf

You can specify multiple directive files in the same command, listed one after another.

Notes

  • Diamond Cabinet Builder (diantz.exe) is identical to makecab.exe; it's included only for legacy support.

  • There are two ways to open Cabinet files and extract their contents. The easiest way is to double-click on any .cab file in Explorer to display a folder view of the contents. You can then drag files out of the .cab file (you cannot add items here, however). The other way is to use the File Expansion Utility (expand.exe).

  • You also can use WinZip (http://www.winzip.com) to open .cab files, but it's not compatible with all variants of the .cab format, and thus it won't open every .cab file you encounter.

  • More complicated directive files, including the use of .inf installation routines, are possible with the Cabinet Maker. See http://msdn.microsoft.com for details, including the use of the /v and /d parameters.

Character Map: \windows\system32\charmap.exe

Display all the characters and symbols in a particular font. This provides access to symbols not easily accessible with the keyboard.

To open

Start All Programs Accessories System Tools Character Map

Command Prompt charmap

Description

Character Map displays a visual map of all the characters in any font, making it easy to paste them into other documents (see Figure 10-10).

Figure 10-10. Character Map, which lets you access the symbols you can't normally type from the keyboard


To use Character Map:

  1. Select a font from the Font drop-down list. If you're inserting a character into an existing document, you should select the same font that is used in the document.

  2. Find the character you want to use; click once on any cell to magnify its character. If you can't find the desired character, remember to scroll down. If the selected font doesn't have the character you want, try another font.

  3. Double-click the character you want (or click once and then click the Select button) to place the character in the "Characters to copy" box. You can place as many successive characters as you want in this box.

  4. Click Copy to copy the character(s) to the Windows Clipboard.

  5. Switch to your other application, click where you want the character(s) to appear, and paste (using either the Edit menu or Ctrl-V).

  6. If the font in the target application isn't the same as the one you've selected in Character Map, you'll need to highlight the newly inserted character(s) and then change it to the same font you used in Character Map. If the character in your document doesn't look as it did in Character Map, it's because the wrong font is being used.

Notes

  • Effective use of Character Map relies on correct font selection, especially when you're pasting characters into applications that don't support multiple fonts. For example, the default font used in Notepad is Lucida Console (which you can change by going to Notepad Format Font).

  • Character Map is helpful not only for selecting extended characters in standard fonts, but also for accessing dingbats, such as those found in the Webdings, Wingdings, Symbol, and Marlett fonts.

  • Character Map is useful for finding out what key combination will produce a nonstandard character in any given font. This can eliminate the need to repeatedly go back to Character Map to retrieve the same character. Select a character in any cell and see the corresponding character code in the status bar. For example, the Yin-Yang symbol in Wingdings is character code 0x5B. Now, this is a hexadecimal code, so you'll need to use the Calculator to convert it to a decimal number. In the Calculator's Scientific mode, click Hex, type the code (not including the 0x prefix--5B in this case), and then click Dec to view the decimal equivalent (91 in this case). To then insert the character into an application using the keyboard, hold down the Alt key and type the code using the numeric keypad (the numbers above the letters won't work). In the case of the Yin-Yang, press Alt and type 91. Appendix C lists some of the most useful character codes.

Default Programs Control Panel

Change a variety of program-related settings, including specifying the default programs to use for various file types and protocols, changing AutoPlay settings, and controlling access to certain programs.

To open

Start Default programs

Description

By default, certain programs are associated with certain file types and protocols and will automatically launch when those files and protocols are opened. For example, by default Internet Explorer opens all .html files and Windows Contacts opens all .vcf filesvCard files that contain contact information. So whenever you double-click to open either of those file typesin Windows Explorer, in Windows Mail, or anywhere elsethe default program will launch and open the file.

The Default Programs Control Panel (Figure 10-11) lets you make changes to those defaults, and lets you change a variety of other settings as well, such as whether CDs, DVDs, and other media should auto-play when inserted.

Figure 10-11. The Default Programs Control Panel, where you can change a variety of program and Windows defaults


The Default Programs Control Panel lets you make these changes:


Set your default programs

Many programs can handle a wide variety of file types, but when they are installed, they are not necessarily the default programs for all those file types. Choosing this option lets you change the default associations on a program-by-program basis. When you click it, the screen shown in Figure 10-12 appears. As you can see, only programs that ship as part of Windows Vista are included; you can't use this option to make changes for other programs. (Notable exceptions include third-party email and web programs such as Mozilla Thunderbird and Firefox.)

Figure 10-12. Configuring the default programs for the file types and protocols handled by core Windows Vista applications

Select the program whose defaults you want to check. If the program is not set to open by default all the file types it can handle, you'll be told the total number of file types it can handle, as well as the total number it is set by default to open. To have it open by default all file types it can handle, click "Set this program as default." To choose some file types but not others, click "Choose defaults for this program" and select from the list.

If the program is already set to open by default any file type it can handle, when you highlight the file it will read "This program has all its defaults."


Associate a file type or protocol with a program

Select this to choose, on a file type-by-file type basis, which programs should open various file types. For example, if you want .mp3 files to be opened by the WinAmp freeware program, you would do that in this screen.

When you make this choice, the Set Associations screen, shown in Figure 10-13, appears. For each file extension, you're shown a description of what the file type is, as well as which program will open it by default. To change which program opens the file by default, click "Change program." You'll be shown the recommended default program, as well as other installed programs that can handle the file. If you want to choose a program not on either list, click Browse to locate it.

Figure 10-13. Setting which programs will open file types from the Set Associations screen


Change AutoPlay settings

This lets you choose what action Windows Vista should take when you insert a CD or DVD into a driveuse AutoPlay to play the media, or let you decide which action to take. It also lets you choose which program should play the media. As you can see in Figure 10-14, you can make choices for a wide variety of media and content, ranging from Blu-ray Disc movies, to mixed content on a CD or DVD, to HD DVD movies, and more.

Figure 10-14. Choosing how Windows Vista decides what actions to take when a CD or DVD is inserted into a drive


Set program access and computer defaults

Several years back, Microsoft fell afoul of the U.S. Justice Department, which claimed that the company was illegally using its Windows monopoly power to promote its own software, such as Internet Explorer, over rivals such as Netscape Navigator. As part of that suit's settlement, Microsoft had to allow PC makers to ship Windows with whatever default programs they wanted for web browsing, media playing, and so on. Microsoft also had to allow consumers to easily change those defaults.

Why am I telling you all this? Because that's the reason for this feature's existence. Click the link, and you'll come to the page shown in Figure 10-15, which lets you choose an overall configuration of select programs for your PC, for web browsing, email, media playing, instant messaging, and using Java.

Figure 10-15. Choosing default programs for web browsing, email, media playing, instant messaging, and using Java

Choose Microsoft Windows, and you'll use all of Windows Vista and Microsoft programs. Choose Non-Microsoft, and not only will your system use non-Microsoft programs for all those purposes, but you'll also disable access to the Microsoft programs. Choose Custom to select a mix of Microsoft and non-Microsoft programs, and to enable or disable access to them.

If Windows Vista came preinstalled on a PC you bought, you may see another option here, Computer Manufacturer, which will restore your settings to those chosen by the manufacturer from which you bought your PC.

Notes

  • Windows Vista offers you far less control over file associations than did Windows XP. In Windows XP, you could set multiple associations for files, as well as customize precisely what actions a program should take when it opens a file. You could, for example, set one program to play a file type by default, but a different program to edit the file by default. None of that is possible in Windows Vista, though.

  • The choices you make in the Default Programs Control Panel are applied to all users of the PC; you cannot choose different settings for different users.

Fax Cover Page Editor: \windows\system32\fxscover.exe

Create and modify cover pages for use with Windows Fax and Scan.

To open

Windows Fax and Scan Tools Cover Pages New

Command Prompt fxscover

Description

The Fax Cover Page Editor (Figure 10-16) works like an ordinary drawing/layout program, in that you can indiscriminately place text, shapes, and images on a blank page. Pages created with the Cover Page Editor are used automatically when sending faxes with Windows Fax and Scan.

Figure 10-16. The Fax Cover Page Editor, which, among other things, enables you to support fields to import data such as recipient names


What makes the Cover Page Editor different from other drawing/layout programs to which you might be accustomed is its support for fields. Naturally, it wouldn't do you much good to create a custom cover page for only a single recipient; rather, it is desirable to create a single cover page (or a series of cover pages) that you can use with any number of recipients. Use the Insert menu to place text fields on the page; fields are divided into the following three categories (menus):


Recipient

Place the name or phone number fields on your cover page, and Windows Fax and Scan will insert those details of the recipient on each fax that is sent out.


Sender

The information in the Sender menu does not change from fax to fax; rather, you set it in the Windows Fax and Scan application (discussed later in this chapter) by going to Windows Fax and Scan Tools Sender Information. Note that it's generally preferred to use fields rather than static text, even if the information contained therein is the same for all faxesit not only makes it easier to change later on, but it also means that your cover pages can be used easily by others.


Message

Like items in the Recipient menu, Message details the message change from fax to fax, such as the subject, time, date, and number of pages.

When you've created or modified the cover pages desired, you must save them into a Cover Page (.cov) file, stored, by default, in \Users\username\Documents\Fax\Personal Coverpages. Then, when sending a fax, simply specify the desired Cover Page file, and it will be used as the first page in your outgoing fax.

You may want to preview outgoing faxes immediately after creating or modifying a cover page to make sure information is inserted into the fields properly.

IExpress: \windows\system32\iexpress.exe

Create a self-extracting/self-installing package, used to distribute files and install applications.

To open

Command Prompt iexpress

Usage

iexpress.exe [/n [/q] [/m]] file [/o:overide file,section]

Description

A self-extracting/self-installing package is actually an application, commonly known as an installer or setup program, that is used to install one or more files onto a Windows system and, optionally, to execute a setup script. IExpress is an interactive program that helps you create these packages, making it easy to, among other things, distribute files to other computers (see Figure 10-17).

Figure 10-17. The IExpress Wizard, which lets you package up a collection of files for easy distribution


Say you want to put together a collection of documents that can be sent to another user, either via email or by using a floppy disk or CD. Rather than simply sending the files separately or compressing them into a .zip file, both of which would require additional instructions (not to mention a reasonably knowledgeable and patient recipient), you can make a full-featured, professional-looking installer with IExpress.

When you start IExpress, the IExpress Wizard guides you through the steps for creating a self-extracting package. The first step prompts for a Self Extraction Directive (.sed) file, a file that contains all the options and files to include. If you don't have one, select "Create new Self Extraction Directive file" and click Next.

The next page, "Package purpose," asks what you want the installer to do with the files on the target computer when the recipient opens the package. If you select the first option, "Extract files and run an installation command," the files will be copied to a temporary folder and a separate installer program that you provide will be launched. If you don't have a separate installation program, choose "Extract files only" and click Next. The last option, "Create compressed files only," is used by application developers to assist in the distribution of application components and is of little use to most users.

The subsequent steps allow you to specify a package title, type welcome and "finished" messages, and even include a license agreement. When you reach the "Packaged files" page, use the Add button to select one or more files to be included in the package; you can choose as many files as you like, and they can be any format. In fact, IExpress will compress the files so that they take up less space (like .zip files). Then, IExpress will ask you to specify a package name, which is the path- and filename of the package (.exe) to be created. IExpress will also optionally save your choices into a Self Extraction Directive (.sed) file, making it easy to re-create this package without having to answer all the aforementioned prompts again.

When the process is complete, you'll end up with a new .exe file that you can run on any Windows system. This package can now be emailed, FTP'd, distributed on a CD or floppy, or even posted on a web site; the recipient won't need any special tools or elaborate instructions to extract the files from the package.

IExpress also has an automated, noninteractive mode for advanced users who want to skip the somewhat cumbersome wizard interface and instead create a package using the following command-line parameters:


file

The full path and filename of a Self Extraction Directive (.sed) file. If you don't have a .sed file, you'll have to use the wizard interface to create one.


/n

Build package now (file must be specified). If you omit /n, IExpress will open in the interactive wizard interface.


/q

Quiet mode (no prompts); used only with /n.


/m

Use minimized windows; used only with /n.


/o

Specify override .sed file and section.


/d

Override directory for .exe stub.

If you've already created a .sed file (say, c:\stuff\thing.sed) and you want to generate the corresponding package without walking through the wizard or being bothered with any prompts, type the following at a command prompt:

iexpress /n /q c:\stuff\thing.sed

The filename of the resulting package will be as specified in the .sed file.

Notes

  • Self Extraction Directive (.sed) files are just plain-text files, similar in format to Configuration Files (.ini), and you can edit them with a plain text editor, such as Notepad. The easiest way to get started with .sed files is to use the IExpress Wizard to create one and then edit (if necessary) to suit your needs.

To open

Start All Programs Accessories Ease of Access Magnifier

Command Prompt magnify

Description

The Microsoft Magnifier is used to assist those with visual impairments by magnifying a portion of the screen. When you start Magnifier, the top 15 percent of the screen turns into an automatic magnifying glass, which follows the mouse cursor around the screen. If you have trouble seeing something on the screen, just float the cursor over it to magnify it (see Figure 10-18).

Figure 10-18. The Magnifier tool, which can follow your mouse cursor, enlarging any portion of the screen you point to


You can resize or move the Magnifier with the mouse. Furthermore, when the Magnifier is first opened, the "Magnifier settings" window appears, allowing you to change the magnification level and choose whether the Magnifier follows the mouse cursor, keyboard focus, or text cursor. To hide the settings window, just minimize it; if you close it, the Magnifier will close.

Notes

  • The Magnifier can also be very handy for application developers and web site authors, who may need to see pixel detail in their work.

Narrator: \windows\system32\narrator.exe

A text-to-speech program intended for visually impaired users.

To open

Start All Programs Accessories Ease of Access Narrator

Command Prompt narrator

Description

The Narrator assists those with visual impairments by using a voice synthesizer and the sound hardware on the user's computer to read aloud text and the titles of screen elements (see Figure 10-19). You can configure the Narrator with these options:


Echo User's Keystrokes

The Narrator will speak each letter, number, and keyboard action as its corresponding key is pressed on the keyboard.


Announce System Messages

The Narrator will speak any Windows Vista system messages as they appear on the screen, as well as the titles of Windows when they are activated and the captions of many types of screen elements.


Announce Scroll Notifications

The Narrator will tell you when the screen scrolls.


Start Narrator Minimized

This will start Narrator minimized to the toolbar.

Figure 10-19. The Narrator, which uses speech to read the captions of various screen elements over your speakers

In addition to these functions, you can use the following keyboard shortcuts to read additional items:

  • To read an entire window, click the window and then press Ctrl-Shift-Space bar.

  • To read the caption of the control with the focus, or to read the contents of a text field, press Ctrl-Shift-Enter.

  • To get a more detailed description of an item, press Ctrl-Shift-Insert.

  • To read the title bar of a window, press Alt-Home.

  • To read the status bar of a window, press Alt-End.

  • To silence the speech, press the Ctrl key by itself.

Notes

  • A far more impressive, related technology is that used in speech recognition software, in which the computer will take dictation, translating anything spoken into a microphone into text on the screen. Although initially developed for physically challenged users, speech recognition has become very popular among all types of users, partly because of the novelty, partly because of the speed (some can type up to 160 words per minute), and partly to help reduce repetitive stress injuries. Windows Vista also comes with a new voice recognition feature, although it's not nearly as sophisticated as NaturallySpeaking (http://www.dragonsys.com) or IBM's ViaVoice (http://www.ibm.com/speech).

Notepad: \windows\notepad.exe

A rudimentary plain-text editor.

To open

Start All Programs Accessories Notepad

Command Prompt notepad

Usage

notepad [/p] [filename]

Description

Notepad is one of the simplest yet most useful tools included with Windows Vista. Those familiar with word processors may find Notepad to be laughably limited at first glance, as it has no support for even the simplest formatting. However, the fact that it supports only text in the documents that it creates is an absolute necessity for many of the tasks for which it is used on a daily basis (see Figure 10-20).

Figure 10-20. Notepad, for editing text files without the bother of a word processor


Among the file types Notepad can edit are .txt files (plain-text files), .reg files (see "Exporting and Importing Registry Data with Patches," in Chapter 13), .bat files (see "Batch Files," in Chapter 14), .ini files (configuration files), .html files (web pages), Unicode, and any other ASCII text-based file type.

Notepad has gained a bit more popularity recently, with the rise of blogging. When you copy and paste text from a word processor, such as Microsoft Word, into some blogging tools, the copied text brings along with it stray bits of code and invisible HTML. This causes problems with the blog. Notepad, on the other hand, handles only text, so it doesn't cause the same problems.

Notepad is the default application for .txt and .log files and is set up as the Edit context menu action for .bat, .inf, and .reg files, among others. Furthermore, via the /p command-line parameter, Notepad is used to print most text-based file types via the Print context menu action.

Notes

  • In some previous versions of Windows, Notepad had a limit as to the size of the documents it could open. The Windows Vista version of Notepad has no such limit, and you can use it to open a file of any size.

  • Notepad has no intrinsic formatting of its own, so any file that is opened in Notepad is displayed exactly as it is stored on the hard disk, with the proviso that only visible characters will be shown. This means that you can open any file, text-based or otherwise, in Notepad; if you try to open a binary file, however, you'll see mostly gibberish. There are times, though, when this can be useful; if you suspect that an image file or a movie file has the wrong extension, you can open it in Notepad to verify its contents. (Naturally, some experience is required to correctly identify different types of files.)

  • The Word Wrap feature (Edit Word Wrap) will break apart long lines of text so that they are visible in the Notepad window without horizontal scrolling. However, no permanent changes will be made to the file, so you can use the Word Wrap feature without fear of damaging the integrity of the document.

  • If you type the text .LOG (in uppercase and including the period) as the first line in a text file, Notepad will automatically place the time and date at the end of the file (with the cursor right below it) every time you open it, forming a simple logfile. Furthermore, you can use the F5 key to manually place a date/timestamp at the current cursor location while editing any file.

  • Notepad is a simple program, but by no means is it a full-featured text editor. UltraEdit (http://www.ultraedit.com) is a much more sophisticated text editor that you also can use as a hex (binary) editor. NoteTab Pro (http://www.notetab.com) is also far more sophisticated, and it includes a very easy-to-use HTML editor as well.

ODBC Data Source Administrator: \windows\system32\odbcad32.exe

Add, remove, or configure sources of database management system data.

To open

Control Panel [System and Maintenance] Administrative Tools Data Sources (ODBC)

Command Prompt odbcad32

Description

Open Database Connectivity (ODBC) is a system that connects ODBC-enabled applications to the database management systems that provide the data. You use the ODBC Data Source Administrator to configure your applications so that they can get data from a variety of database management systems. For example, if you're using an application that accesses data in an SQL database, the ODBC Data Source Administrator lets you connect that application to a different data source, such as a Microsoft Excel spreadsheet or a Paradox database.

In the ODBC Data Source Administrator, the different sources of data are called data providers. To add a new provider, click Add under the User DSN, the System DSN, or the File DSN tab. A list of the available drivers is listed under the Drivers tab; you can install new drivers separately. The Tracing tab allows you to log the communication between applications and the ODBC data sources they use. You use the Connection Pooling tab to improve performance with ODBC servers. Finally, you use the About tab to check the versions of the installed ODBC components.


On-Screen Keyboard: \windows\system32\osk.exe

A full, on-screen keyboard controlled by the pointing device.

To open

Start Programs Accessories Accessibility On-Screen Keyboard

Command Prompt osk

Description

Among the tools provided with Windows XP to assist users with physical disabilities is the On-Screen Keyboard. Intended to be used by those who are unable to comfortably use a keyboard, the On-Screen Keyboard allows any key normally available on the keyboard to be pressed with a click of the mouse, or whatever pointing device is currently being used (see Figure 10-21).

Figure 10-21. The On-Screen Keyboard, which lets you type by pointing and clicking


What makes the On-Screen Keyboard especially appropriate as a primary input device is that you can click keys when another application has the focus. For example, open the On-Screen Keyboard and then open your word processor; the keyboard will float above the word processor, allowing you to click any key to "type" it into your document.

Configuring the On-Screen Keyboard is straightforward. Use the Keyboard menu to change the layout of the keys, or Settings Font to change the font of the key labels. Go to Settings Typing Mode to choose how keys are pressed; by default, each key must be clicked, but you can set it up so that you can hover over keys to select them, or even use a joystick to control the keyboard.

Notes

  • Also included with Windows Vista is the Character Map (discussed earlier in this chapter), which allows access to symbols and other characters not normally available on a standard keyboard. However, only the On-Screen Keyboard is designed to be a primary input device.

Private Character Editor: \windows\system32\eudcedit.exe

Create special characters, such as logos or symbols, that can be inserted into ordinary documents.

To open

Command Prompt eudcedit

Description

The Private Character Editor is like a small-image editor, except that the images created with it are used like symbol fonts, making it easy to insert any custom logo or symbol into your documents.

When you first start the Private Character Editor, you'll be presented with a rather confusing Select Code window. You use this to associate the new (or existing) character you'll be editing with a particular slot, and it is somewhat akin to the main Character Map window. Select any slot and click OK to proceed.

The main window contains the character editor and a simple set of drawing tools (such as those found in Paint). Each character is a 50 x 50 black-and-white bitmap. Draw in black with any of the available tools and the left mouse button; draw in white with the right mouse button. You can copy and paste bitmap selections between the Private Character Editor and other image editing programs, such as Paint.

When you're done, save your work into the slot you chose in the first screen by going to Edit Save Character (Ctrl-S). Or, save it into a different slot by going to Edit Save Character As. At any time, you can choose a different slot to edit with Edit Select Code, or with View Next Code (Ctrl-N) and View Prev Code (Ctrl-P). As you choose slots in which to place your new characters, you can use another font as a reference to decide which are the most convenient slots to use. Select Window Reference to view the orientation of an existing font on your computer.

To use your new character in another application, open Character Map (charmap.exe) and choose All Fonts (Private Characters) from the top of the list. If this entry is not present, you didn't save your work. See "Character Map," earlier in this chapter, for more information on pasting characters into other applications.

Program Compatibility Wizard

Configure older programs to help them run under Windows Vista.

To open

Control Panel Programs Use an older program with this version of Windows

Description

Old programs, especially old DOS-based programs and games, may have problems running under Windows Vista. The Program Compatibility Wizard helps you troubleshoot problems with those programs, and help them run under Windows Vista.

Run the wizard, then choose the program from a list of programs, browse for it on your hard disk, or choose a program in your CD or DVD drive. After you select it, you can choose one of five compatibility modesWindows 95, Windows NT 4.0 (Service Pack 5), Windows 98/Me, Windows 2000, or Windows XP (Service Pack 2). Choose the version of Windows under which the program was developed or worked previously. When you do that, the Program Compatibility Wizard will apply settings so that whenever the program runs, it will in essence think it's running under the older operating system, and all should be right in its world. So, for example, it may run at 256 colors and in 640 x 480 resolution.

What if that doesn't work, or if you don't know under what version of Windows it previously ran? Choose "Do not apply a compatibility mode" instead. You'll be walked through a series of screens letting you manually choose settings (Figure 10-22), such as under what screen resolution and color depth to run the program, whether to run the program as an administrator, and so on. When you're done, if the program still doesn't work, go back in and change the settings until you find a set that works.

Figure 10-22. Choosing how to run an older program to get it to work in Windows Vista


Notes

  • You shouldn't use the Program Compatibility Wizard with older virus detection, backup, or system programs, because using those older programs on Windows Vista can potentially cause serious system problems.

  • If you're experiencing problems with the program's menus, buttons, or title bar, check the box next to "Disable visual themes" when you're choosing your settings manually. Select "Disable desktop composition" if you're experiencing problems with the display.


Rundll32: \windows\system32\rundll32.exe

Run a single routine in a DLL file from the command line.

To open

Command Prompt rundll32

Usage

rundll32 filename,function_name [function_arguments . . . ]

Description

Rundll32 provides "string invocation," which lets you execute a command buried in a Dynamic Link Library (DLL) file.

Rundll32 accepts the following options:


filename

The filename of a DLL (.dll) file.


function_name

The case-sensitive name of a function in the DLL file.


function_arguments

Any parameters used by function_name; refer to the function's documentation for details. Note that any string parameters are case-sensitive.

Examples

The following example switches the functions of the mouse buttons so that the right operates as the left, and vice versa. Note, though, that it doesn't work as a toggle, so you can't use the command again to switch the functions back.

RUNDLL32.EXE USER32.DLL,SwapMouseButton

This batch file allows you to display an Open As dialog box for unknown file type .xyz without actually having a file of type .xyz handy (see Chapter 14 for more information about batch files):

echo blah blah blah > foobar.%1
rundll32 shell32.dll,OpenAs_RunDLL foobar.%1

Then type the following at a command line:

C:\>openas xyz

Notes

  • Rundll32 provides dynamic linking to functions exported from 32-bit DLLs. Rundll, the 16-bit equivalent found in versions of Windows before Windows XP, is not included in Windows Vista.


Uninstall or Change a Program: \windows\system32\appwiz.cpl

Uninstall programs, or add or remove extra program features.

To open

Control Panel Programs Programs and Features

Command Prompt appwiz.cpl

Description

This Control Panel applet (Figure 10-23) lets you uninstall any program on your PC, as well as change the program by adding new features, or repair the program if for some reason it has been damaged.

Figure 10-23. The Control Panel applet where you can uninstall programs


To uninstall a program, double-click it and follow the prompts that appear. (You can also right-click it and choose Uninstall.) To add new features or remove features from the program, right-click it and select Change. In many instances, you'll need the CD or DVD from which you installed the program in order to addand sometimes removefeatures. You'll be prompted for the CD or DVD. Right-click and choose Repair to fix a damaged programand again, you'll usually need the CD or DVD installation disk in order to do that.

The Uninstall or Change a Program applet also lets you turn Windows features and programs on and offfeatures and programs such as games, Windows Media Player, and so on. Click "Turn Windows features on or off," and the screen shown in Figure 10-24 appears. Turn a feature on by checking the box next to it; turn it off by unchecking the box. Note that turning off a Windows feature doesn't actually delete the files from your hard disk; it only turns off access to them. In this way, when Windows Update runs, you know that every possible program you could run is safe (otherwise, if you had to install the program anew from Windows DVD, you could install older, buggy versions).

Notes

  • Remove or disable add-ins to Internet Explorer and/or ActiveX controls using Internet Explorer. In Internet Explorer, choose Tools Manage Add-ons Enable or Disable Add-ons.


Windows CardSpace

Send and receive faxes, including scanning documents to be faxed.

To open

Control Panel [User Accounts and Family Safety] Windows CardSpace

Description

Windows CardSpace, formerly known as InfoCard, stores "cards" that identify you to web sites, services, and applications, and let you log on to them automatically. When you visit a CardSpace-enabled web site or run a CardSpace-enabled application and the application or site needs to get information from you, Windows CardSpace automatically runs, displays all the cards you've created, and lets you select the appropriate one. The information is then sent to the site or application.

Windows CardSpace is self-explanatory; click Add Card to create a new card, Delete Card to delete an existing card, and so on.

Notes

  • As of this writing, Windows CardSpace is not particularly popular, and very few web sites and applications use it, just as very few used its predecessor, InfoCard. So you may not want to spend much time using this Windows Vista feature.

  • For security purposes, when you create or manage your cards, your screen turns into Windows Vista's Secure Desktop, in which the background of the screen is dark and only the Windows CardSpace area is live. When the Secure Desktop is running, only trusted processes are allowed to run, making for increased security.


Windows Fax and Scan: \windows\system32\WFS.exe

Send and receive faxes, including scanning documents to be faxed.

To open

Start Windows Fax and Scan

Command Prompt wfs

Description

Windows Fax and Scan lets you send, receive, and manage all incoming and outgoing faxes (see Figure 10-25). It is set up like Outlook Express, with folders shown in a hierarchical tree in the left pane and the contents of the currently selected folder shown in the right pane.

Figure 10-25. Windows Fax and Scan, which lets you view and manage all incoming and outgoing faxes


Windows Fax and Scan lets you create documents to fax with its message editor, which looks much like the editor included with Windows Mail. You can use different fonts and font attributes, embed graphics, and so on, and then fax the document.

If you have a document on paper that you need faxed, you can use the scan features to scan the document and then fax it. Switch between the fax and scanning features by clicking either Fax or Scan at the bottom of the screen.

Windows Fax and Scan works much like an email program. For example, if you receive a fax and want to respond to it, click Reply, and you'll be able to send a fax back to the sender, using the built-in editor to create it. You can even take a fax you've gotten, attach it to an email, and send it. (Click Forward as E-Mail.) Of course, it prints faxes as well.

If you're attached to a network that has a network fax, you can use that instead of a fax connected to your PC.

If you create documents using Word, Excel, or other applications that you want to fax, you can instead fax the documents straight from the application. Applications consider the fax as little more than a remote printer connected to a phone line. Print as you normally would, except choose Fax instead of your normal printer. After your application has sent the document to the fax printer driver, a new wizard appears and asks you for the recipient name and phone number, as well as any queuing options (useful if you want to postpone sending the fax until off-peak hours).

To receive faxes, start Windows Fax and Scan and click Receive a Fax Now.

Notes

  • Not surprisingly, if you don't have a modem, you won't be able to send or receive faxes; you can't send them from Windows Fax and Scan via the Internet.

  • If you want to receive faxes but don't have a modem, or if you just don't want to leave Windows Fax and Scan running all the time, Internet-based fax services (such as http://www.efax.com), some of which are completely free, send incoming faxes to you as email attachments.

  • An alternative to using faxes is to email documents and scans. A program such as Adobe Acrobat (http://www.adobe.com) is especially useful for preserving fonts and formatting in computer-generated documents, and it can even accommodate scanned pages, making it easy for the recipient to view or even print them. Not only will this result in higher-quality documents and lower phone bills, but it also might save a few trees. You can also use Windows Vista's built-in XML Paper Specification (XPS) file format for the same purpose, although the document can then be shared only with people who use Windows Vista or an XPS viewer. XPS isn't in as widespread use as Acrobat. For more details, see "XPS Document Viewer," in Chapter 9.

Windows Speech Recognition: \windows\Speech\Common\sapisvr.exe

To open

Start All Programs Ease of Access Windows Speech Recognition

Command Prompt sapisvr.exe -SpeechUX

Description

Windows Speech Recognition lets you dictate to Windows, which will recognize your speech and input it into an application. In addition, you can use spoken commands to perform tasks, such as opening files, saving files, switching between applications, and so on.

You'll need a microphone for speech recognition to work. The first time you start the application, a wizard runs, letting you configure your hardware. In addition, a tutorial will run, teaching you how to use the program.


WordPad: \Program Files\Windows NT\Accessories\wordpad.exe

A simple word processor.

To open

Start All Programs Accessories WordPad

Command Prompt wordpad

Description

Although WordPad lacks many of the features that come with full-blown word processors such as WordPerfect and Microsoft Word, it has enough features to let you create and edit rich-text documents. WordPad is the default editor for .rtf, .doc, and .wri files (unless Microsoft Word is installed). You also can use WordPad to edit plain-text files (.txt), although Notepad (discussed earlier in this chapter) is the default and is more appropriate for this task (see Figure 10-26).

Figure 10-26. WordPad, the rudimentary word processor that comes with Windows XP


Depending on the type of file opened, WordPad may or may not display its formatting toolbar and ruler. When you use File New, WordPad prompts you to choose a document type, including Rich Text Document (formatted text, such as word processor documents), Text Document (plain ASCII text), and Unicode Text Document (plain text using the Unicode character set). Once a file is open, however, you can turn on or off the formatting bar and ruler and even apply formatting to plain-text documents. If you try to save a text document with formatting, though, WordPad will warn you that your formatting will be lost (because text files don't support formatting).

WordPad has several advantages over the simpler Notepad application. Among other things, WordPad lets you choose from a wide selection of fonts and font sizes, use colors in your documents, set tab stops, use rulers, and even insert objects (e.g., images, some clips, etc.). Although not a full-featured word processor, WordPad does enough to create simple formatted documents that can then be printed, emailed, or faxed.

Notes

  • You can open Microsoft Word documents with WordPad, but you might lose some formatting if you save the file (which will prompt WordPad to warn you).

  • When dragging a file onto WordPad, be sure to drop the file icon onto the WordPad title bar if you want to view it or edit it, or drop it onto the middle of the document if you want to embed the icon as an object into the currently open document.

  • To prevent WordPad from overwriting your file extensions and adding its own when you save a file, place quotation marks around the name of the file you want to save (e.g., "read.me") and click Save. Otherwise, you'll get read.me.doc.

  • Like Notepad, WordPad does not allow you to open more than one document at a time. If you want to view multiple WordPad documents simultaneously, you'll need to open multiple instances of the WordPad application.
