Chapter 3 — Installing Applications

74 CN2B Mobile Computer User’s Manual

Packaging an Application

Use any of these methods to package an application for installation:

• For very simple applications, the application itself might be the only file

that needs to be delivered.

• It could be a directory structure that contains the application, supporting

files like ActiveX controls, DLLs, images, sound files, and data files.

• 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:

• In the basic CN2B Computer, there are two built-in storage options: the

Object Store and the Persistent Storage Manager (PSM). The Object

Store is RAM that looks like a disk. Anything copied here is deleted

when a cold-boot is performed on the CN2B 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, how-

ever, be erased during the reflashing process. In addition to storing appli-

cations and data files, you do have the option to store a persistent registry

to the PSM region.

• If the optional Secure Digital storage card is in the system, then consider

this card the primary location for placing an applications install files.

This storage card creates the “\Storage Card” folder.

• Use the small nonvolatile 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 CN2B Computer — providing the AutoRun system is installed in the

appropriate location You can find this system in the CN2B 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 83).

Installing Applications

Consider any of these options to get the package to the preferred location

on your CN2B Computer: Microsoft ActiveSync (page 75), FTP Server

(page 76), Secure Digital storage cards (page 76), Wavelink Avalanche

(page 76), SmartSystems™ Console (page 77), or Registry (page 77).
