Sent to the clipboard owner if it has delayed rendering a specific clipboard format and if an application has requested data in that format. The clipboard owner must render data in the specified format and place it on the clipboard by calling the SetClipboardData function.
#define WM_RENDERFORMAT 0x0305
The clipboard format to be rendered.
This parameter is not used.
If an application processes this message, it should return zero.
When responding to a WM_RENDERFORMAT message, the clipboard owner must not open the clipboard before calling SetClipboardData. Opening the clipboard is not necessary before placing data in response to WM_RENDERFORMAT, and any attempt to open the clipboard will fail because the clipboard is currently being held open by the application that requested the format to be rendered.
