SCANAPIAX.DLL
We supply SCANAPIAX.DLL to allow programmer to control the on-board scanning device.
There are several functions available for programmer to tailor the application. Programmer can
also use Windows CE development tool, such as Visual Studio 2005, to develop application
program and control the on-board scanning device.
In the SCANAPIAX.DLL library, there are three functional groups can be used to control the
scanning device. They are API_SCAN, Scan2Key, and Scanner related functions. Each functional
group can be used to control the scanning device in different ways. These three functional groups
can not be used at the same time. Programmer should select the most appropriate way to develop
target application. The following shows function list of each functional group.
