Take photos with Dolphin 99EX on Windows Mobile 6.5.3 Professional DTK(ARMV4I)

Question

My problem is the next:
I have an application developed for Windows Mobile 6.5.3 Professional DTK(ARMV4I) which is running on Honeywell Dolphin 99EX.
Basically I am using the API from Honeywell to take pictures: CameraAPI.h.
The problem is at the photo camera initialization.
In the working project every time when I call camInit function it returns RESULT_ERR_NOTCONNECTED.
If I am creating a test project and try same thing it is working.

From what I saw in debug console at camInit calling:

1. The test project which is working loads:
Load module: quartz.dll.0409.MUI
Load module: MMTimer.dll
Load module: quartz.dll
Load module: msdmo.dll
Load module: wmvdmoe.dll
Load module: icm.dll
Load module: msrle32.dll
Unload module: msrle32.dll
Unload module: icm.dll
Load module: DDRAW.dll

and after that camInit returns 0.

2. The working project which is not working loads:
Load module: quartz.dll.0409.MUI
Load module: MMTimer.dll
Load module: quartz.dll

and after that camInit returns RESULT_ERR_NOTCONNECTED.

It loads only the first 3 dlls from a normal workflow.
Do you know why the working project stops to load the rest of the dlls?
Or do you know an approach to fix the problem?

Thanks

Answer 1

On the 99EX, the camera and the decoder use the same hardware bus and cannot both be initialized and connected at the same time. Before calling camInit(), call decDisconnect() (c++) or DecodeAssembly.Disconnect() (c#).
