CWnd::ReleaseDC

Syntax

int ReleaseDC( CDC* pDC );

Parameters

pDC

Identifies the device context to be released.

Remarks

Releases a device context, freeing it for use by other applications. The effect of the ReleaseDC member function depends on the device-context type. It only frees common and window device contexts. It has no effect on class or private device contexts.

The application must call the ReleaseDC member function for each call to the GetWindowDC member function and for each call to the GetDC member function that retrieves a common device context.

Return Value

Specifies whether the device context is released. It is 1 if the device context is released; otherwise 0.
