Hi,
This is my code for capture the image from Web camera

m_Palette = 0;
   // Open handle in an invisible window
   m_CapHandle = capCreateCaptureWindow((LPTSTR)"Capture Window",
#if 1
                                        0,

#else

      CVideoCollector::Instance((QWidget *) m_CapHandle)->RegisterDevice(m_CapHandle, this);
