    using CreateDIBSection()

    My project inputs a telemetry stream that includes a real time image. From various places I have put together some code that seems like it should create a DIB and be ready to use. But the call to CreatDIBSection leaves my_bitmap and the pointer ppvBits both set to zero. The GetLastError...

    combo box, extremely simple

    Visual Studio 2008, MFC, Windows XP I created a combo box with a drop down that displays the numbers 01 through 12. The range will never change. The name is IDC_STREAM_NUMBER. After creating an even handler the name IDS_STREAM_NUMBER doesn't like putting the -> or . (dot) notation after it...

    I have an std::map that is working, but there are problems when I try to empty it. The declaration looks like this: std::map< int, DP_MESSAGE_STRUCT * > m_dp_messages; std::map< int, DP_MESSAGE_STRUCT * >::iterator m_msg_iterator; I can put data in the map and read the data. The structure has...
