CPaintDC::CPaintDC

  • 项目

CPaintDC(CWnd*pWnd);
throw(CResourceException);

Parameters

pWnd

Points to the CWnd object to which the CPaintDC object belongs.

Remarks

Constructs a CPaintDC object, prepares the application window for painting, and stores the PAINTSTRUCT structure in the m_ps member variable.

An exception (of type CResourceException) is thrown if the Windows call fails. A device context may not be available if Windows has already allocated all of its available device contexts. Your application competes for the five common display contexts available at any given time under Windows.
