Hi,
I am looking for insight into deploying the Windows Message Queue functions with the AppBuilder. I have a custom USB HID device that I want to receive messages or callbacks when it attaches or detaches from the computer. I used 3rd party, AHID library to handle messages with a specific device, but am having difficulty determine when a device is availalbe to connect.
The windows message mechanism works in my labview environment, in that I see the callbacks for each device connection, and disconnection. however, I simplified the VIT to a regular VI and put it in a specific folder for app-builder. The EXE does not seem to get the same windows messages as the development system.
I saw a comment in the DLL source,
"//GetProcAddess may fail if this DLL is called from a LabVIEW built application. Get Occur from lvrt.dll.
I am testing in a LabVIEW built application and not receiving the same messages as from the Dev environment. Any thoughts?
