CDC::m_hDC
Visual Studio 2005
The output device context for this CDC object.
HDC m_hDC;
By default, m_hDC is equal to m_hAttribDC, the other device context wrapped by CDC. In general, CDC GDI calls that create output go to the m_hDC device context. You can initialize m_hDC and m_hAttribDC to point to different devices. See the CDC class description for more on the use of these two device contexts.
