Sent to the clipboard owner by a clipboard viewer window when the clipboard contains data in the CF_OWNERDISPLAY format and the clipboard viewer's client area needs repainting.
#define WM_PAINTCLIPBOARD 0x0309
A handle to the clipboard viewer window.
A handle to a global memory object that contains a PAINTSTRUCT structure. The structure defines the part of the client area to paint.
If an application processes this message, it should return zero.
To determine whether the entire client area or just a portion of it needs repainting, the clipboard owner must compare the dimensions of the drawing area given in the rcPaint member of PAINTSTRUCT to the dimensions given in the most recent WM_SIZECLIPBOARD message.
The clipboard owner must use the GlobalLock function to lock the memory that contains the PAINTSTRUCT structure. Before returning, the clipboard owner must unlock that memory by using the GlobalUnlock function.
