Hi there, I am trying to use Symbol.Imaging.dll in EMDK v2.3 (.NET version) to take a photo/video with MC75A0. I tried the sample code: CS_ImagerSample1 and my own application, both failed in the following code:   try {   imager = new Symbol.Imaging.Imager(Symbol.Imaging.Device.AvailableDevices[0]); } catch ... The exception was IndexOutOfRangeException. Printing the value of Symbol.Imaging.Device.AvailableDevices.Length, the length is 0, which means there is no imaging device available. My VS2008 debugger also displayed: A first chance exception of type 'Symbol.Exceptions.OperationFailureException' occurred in Symbol.Imaging.dll My Device:  MC75A0 My Dev. Environment: VS2008 on Win7(64bits), EMDK v2.3 (.NET version) The WM6.5 camera application works fine, and the API: Microsoft.WindowsMobile.Forms.CameraCaptureDialog works well too. Does anyone experience the similar issue? Thanks Jason
