Introduction to the MobileView SDK 1-9

PCMCIA

New or upgraded components of application programs and the

operating system can be copied from the PCMCIA memory card to

Storage Card memory to replace and upgrade the existing

components.

In the Windows Explorer, the PCMCIA Memory Card will show up as

an icon named “\Storage Card”.

Application Run Time Environment

Path

The notion of a path to executable files is much the same as with any

other Windows or DOS system. However, unlike other systems, which

refer to an environment variable for path settings, Windows CE

utilizes a registry entry. Thus, the path can be set only by editing the

value of the registry key \HKLM\Loader\SystemPath. Note the use of

spaces to separate items in the path list, as in the following example:

“\Storage Card\bin\ \Storage Card\ \ Storage Card\bin\ \Storage

Card\ ...”

Launching Applications At Start-Up

The Windows CE Registry entries at key HKLM\init determine the

programs that are started during system initialization, and the order in

which they are started. The Windows CE Platform Builder

development tool (not part of the Embedded Visual C 4.x) is used to

establish these Registry entries.
