Default Progress Bar Message Processing

This section describes the window messages handled by the window procedure for the PROGRESS_CLASS window class.

Message	Processing performed
WM_CREATE	Allocates and initializes an initial structure.
WM_DESTROY	Frees all resources associated with the progress bar.
WM_ERASEBKGND	Draws the background and borders of the progress bar.
WM_GETFONT	Returns the handle of the font that the progress bar is currently using to draw text.
WM_PAINT	Draws the progress bar. If the wParam parameter is non-NULL, the control assumes that the value is an HDC and paints using that device context.
WM_SETFONT	Saves the handle of the new font and returns the handle of the previous font.
