Streaming Using Events In C#

Can anyone get the example from the documentation to work.

When I try it the OnNewSample is never called.

pxcmStatus OnNewSample(Int32 mid, PXCMCapture.Sample sample) {

if (sample.color!=null) {

// work on the color sample

...

}

if (sample.depth!=null) {

// work on the depth sample

...

}

// return NO_ERROR to continue, or any error to exit the loop

return pxcmStatus.PXCM_STATUS_NO_ERROR;

};

void CaptureUnalignedColorDepthSamples() {

PXCMSenseManager sm=PXCMSenseManager.CreateInstance();

// select the color and depth streams

sm.EnableStream(PXCMCapture.StreamType.STREAM_TYPE_COLOR,640,480,30);

sm.EnableStream(PXCMCapture.StreamType.STREAM_TYPE_DEPTH,320,240,30);

// Initialize my handler

PXCMSenseManager.Handler handler=new PXCMSenseManager.Handler();

handler.onNewSample=OnNewSample;

sm.Init(handler);

// Streaming

sm.StreamFrames(true);

// Clean up

sm.Dispose();

}

To make my question clearer -

To make my question clearer - does the event handler approach work and if so why do none of the samples use it?

They all create a new thread and run the polling loop there which is what the event handler approach is supposed to do for you.
