Example

This example creates .cab files for the ARM and MIPS microprocessors,
assuming the Win32 Setup.inf file contains the ARM and MIPS tags:

cabwiz.exe “c:\myfile.inf” /err myfile.err /cpu arm mips

Troubleshooting the CAB Wizard

To identify and avoid problems that might occur when using the CAB
Wizard, follow these guidelines:

• Use %% for a percent sign (%) character when using this character in an

.inf file string, as specified in Win32 documentation. This will not work
under the [Strings] section.

• Do not use .inf or .cab files created for Windows CE to install

applications on Windows-based desktop platforms.

• Ensure the MakeCab.exe and CabWiz.ddf files, included with Windows

CE, are in the same directory as CabWiz.exe.

• Use the full path to call CabWiz.exe.

• Do not create a .cab file with the MakeCab.exe file included with

Windows CE. You must use CabWiz.exe, which uses MakeCab.exe to
generate the .cab files for Windows CE.

• Do not set the read-only attribute for .cab files.

Customization and Lockdown

Some customers would prefer that their users not have access to all of the
operating system features. Intermec cannot customize the operating system
in any way but a custom application can:

• Delete items from the Start menu, and Programs folder. These items are

just shortcuts in the file system so the application is not really being
deleted. Cold booting the device will bring these items back so the
application will need to be run on every cold boot.

• Use the RegFlushKey() API to save a copy of the registry to a storage

device. See the IDL for more information on how to do this. Saving a
copy of the registry restores most system settings in a cold boot situation.

• Use the SHFullScreen() API with other APIs to have the application take

up the entire display and prevent the Start menu from being available.

• Remap keys and disable keys on the keypad; create a custom SIP; or

• Make changes to the registry to configure the device.

Note: CabWiz.exe, MakeCab.exe, and CabWiz.ddf (Windows CE files
available on the Windows CE Toolkit) must be installed in the same
directory on the desktop computer. Call CabWiz.exe using its full path for
the CAB Wizard application to run correctly.
