The WM_PALETTEISCHANGING message informs applications that an application is going to realize its logical palette.


hwndRealize = (HWND) wParam; // window to realize palette 



Value of wParam. Identifies the window that is going to realize its logical palette.

Return Values

If an application processes this message, it should return zero.


The application changing its palette does not wait for acknowledgment of this message before changing the palette and sending the WM_PALETTECHANGED message. As a result, the palette may already be changed by the time an application receives this message.

If the application either ignores or fails to process this message and a second application realizes its palette while the first is using palette indices, there is a strong possibility that the user will see unexpected colors during subsequent drawing operations.
