The MV VideoSourceComboBox is an ActiveX Control which enumerates all available video sources. Use this control to select a video source within your applications.
This MontiVision ActiveX Control is used in combination with the MontiVision Smart Control and the MV Demo Source DirectShow Filter in most of the Smart Control Sample Applications.

How To Use
The first step ist to insert the control into your dialog form. To replace a video source in an filter graph configuration you have to set the new source before loading the MontiVision Project File (*.mvp). Call the SetSourceFilter() method from IMVSCSetSourceFilter interface of the MV Smart Control. Read this HowTo for more information.
Example Code C++:
// Init Video Source
CComBSTR bstrSelectedDevice = m_comboVideoSource.GetSelectedDevice();
m_pISetSource->SetSourceFilter(bstrVideoSource.m_str, bstrSelectedDevice.m_str);
// Load configuration
CComBSTR bstrPath(".\\recording.mvp");
m_pIFilterGraph->LoadConfig(bstrPath.m_str);
