Packaging an Application

86
Use any of these methods to package an application for installation:
S For very simple applications, the application itself might be the only file
that needs to be delivered.
S It could be a directory structure that contains the application, support-
ing files like ActiveX controls, DLLs, images, sound files, and data files.
S Or, you could package an application via a CAB file.
Consider any of the following when choosing a location into which to
store your application:
S In the basic 700 Color Computer, there are two built-in storage op-
tions: the Object Store and the Persistent Storage Manager (PSM). The
Object Store is RAM that looks like a disk. Anything copied here is de-
leted when a cold-boot is performed on the 700 Color Computer. The
PSM is an area of storage which is embedded in a section of the system's
FLASH memory. This storage area is not erased during a cold-boot. It
may, however, be erased during the reflashing process. In addition to
storing applications and data files, you do have the option to store a per-
sistent registry to the PSM region.
S If the optional Secure Digital or CompactFlash storage card is in the
system, then consider this card the primary location for placing an ap-
plications install files. The following folders represent either card:
S The Secure Digital storage card creates the "\SDMMC Disk" folder.
S The CompactFlash storage card creates the "\Storage Card" folder.
Note: 730 Computers do not support Compact Flash storage cards.
Instead, the "\Storage Card" folder is created for the Secure Digital
storage card.
S Use the small non-volatile Flash File Store region to hold CAB files that
rebuild the system at cold-boot or install applications from a CAB file
into the Flash File Store so they are "ready-to-run" when a cold-boot is
performed. Since the FLASH in the system has a limited number of
write cycles, do not use the Flash File Store for excessive writing pur-
poses; however, reading is okay.
Files copied to any of these locations are safe when a cold-boot is
performed on a 700 Color Computer — providing the AutoRun system is
installed in the appropriate location Find this system in the 700 Color
Management Tools portion. Copying a CAB file to the "\CabFiles" folder
on one of these cards automatically extracts that CAB file on every
cold-boot to ensure that your system is properly set up (see page 95).
