WM_PALETTEISCHANGING
The WM_PALETTEISCHANGING message informs applications that an application is
going to realize its logical palette.
WM_PALETTEISCHANGING
hwndRealize = (HWND) wParam; // window to realize palette
Parameters
hwndRealize
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.
Remarks
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.
