Building and Deploying the Application
To build and deploy the application to the JETT•RFID:

From the Build Menu, select
Build HelloWorld.exe
.

eMbedded Visual C++ 4.0 will then compile the program and attempt communication via
ActiveSync with the JETT•RFID to download the application. After the transfer completes,
you can then run the application on the JETT•RFID.

On the JETT•RFID, navigate to the My Computer folder and double-tap the HelloWorld icon
to run the application.

Storing the Application Files”
When eMbedded Visual C++ 4.0 deploys the HelloWorld application to the JETT•RFID, it also copies
the Mfcce400d.dll file to the \Windows folder. Both files are temporarily stored in the unit’s DRAM.
As long as the JETT•RFID remains powered on, you will be able to execute the HelloWorld application.
If you turn the power off, the application files will be lost.
To store the files permanently, you can either copy the files to internal compact flash (i.e., the SystemCF
folder) or to a memory card.
