As you migrate from a 700 Monochrome Computer to a 700 Color Com-
puter, you need to consider the following: When converting a 700 Mono-
chrome Computer application to run on the 700 Color Computer, most
APIs should work without changes. Below are a few exceptions:
S The 700 Monochrome Computer uses the "\Storage Card" folder for
nonvolatile storage. You may need to change the application to store
data onto the "SDMMC Disk" folder instead of the "\Storage Card"
folder if a Secure Digital storage card is present in the system.
S If the application uses the RegFlushKey() API, it must first verify that
the proper media is available in the system and call the special API men-
tioned in Step 7 on the previous page.
S If the application is using the 700 Color switchable dock, use the
IOCTL_DOCK_SWITCH value from the
IOCTL_HAL_ITC_WRITE_SYSPARM function to set the proper
port on the dock before communications. See more information about
this KernelIOControl function in Chapter 7, "Programming."
S Some WAN radio options have changed. Review the WAN radio infor-
mation in Chapter 4, "Network Support,"to determine if any changes are
required in your application.
S Arrow and tab keys are reversed from the 700 Monochrome Computer.
Keyboard remapping is available on the 700 Color Computer should
you need to map these keys like that of the 700 Monochrome Comput-
er (see page 121).
S Special SDKs are not needed to compile applications for the Xscale pro-
cessor. Targeting the SA1110 processor creates applications that run on
the 700 Color Computer.
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 700 Color Computer, CAB files register DLLs, create shortcuts,
modify 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 de-
vices in the "\CabFiles" folder, then perform a warm-boot on the 700 Col-
or Computer. There are two methods available to extract a CAB file:
S 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.
S Use the AUTOCAB method to extract all files when a cold-boot is per-
formed on the 700 Color Computer. This method is on the Intermec
Developer's Library CD, see its Software Tools User's Manual for informa-
tion.
