Chapter 3 — Installing Applications

CN2B Mobile Computer User’s Manual 83

Migrating from Another Computer

As you migrate from another mobile computer to a CN2B Computer, you

need to consider the following: When converting an application to run on

the CN2B Computer, most APIs should work. Below are a few exceptions:

• The other computer may use the “\SDMMC Disk” folder for nonvola-

tile storage. You may need to change the application to store data onto

the “Storage Card” folder instead of the “\SDMMC Disk” folder if a

Secure Digital storage card is present in the system.

• If the application uses the RegFlushKey() API, it must first verify that

the proper media is available in the system.

• Keyboard remapping is available on the CN2B Computer should you

need to map these keys like that of the original computer (see

page 182).

• Targeting the ARM (SA1110) processor which creates applications that

run on the CN2B Computer requires the Windows Mobile 2003 SDK.

Installing Cabinet Files

CAB files (short form of “cabinet” files) are compressed folders as defined by

Microsoft. A “cabinet” file is a single file, usually suffixed with .CAB, that

stores compressed files in a file library. A compressed file can be spread over

several cabinet files. During installation, the setup application decom-

presses the files stored in a cabinet and copies them to the user’s system.

For the CN2B Computer, CAB files register DLLs, create shortcuts, mod-

ify registry entries, and run custom setup programs. Tap a CAB file to

extract that file or place the CAB file on one of the approved storage devices

in the “\CabFiles” folder, then perform a warm-boot on the CN2B Com-

puter.

There are two methods available to extract a CAB file:

• Tap a CAB file to extract it. With this method, the CAB file is automat-

ically deleted when the extraction process is successful, unless the CAB

file is set with the read-only attribute.

• Use AUTOCAB to extract all files when a cold-boot is performed on the

CN2B Computer. See the Software Tools User’s Manual for information.
