Very nice wolf9228, I like the tiled version when you have

$Form = GUICreate("Form", 128, 128, 303, 100,BitOr($GUI_SS_DEFAULT_GUI , $WS_SIZEBOX))

I think you should set those styles in your example, but it messes up the center version.

It's not obvious to me what the advantage is of the centre and stretched versions over using GuiCtrlCreatePic with the relevant resizing options which would be simpler.

The WM_ERASEBKGND message is sent when the window background must be erased (for example, when a window is resized). The message is sent to prepare an invalidated portion of a window for painting.

Problem when loading the Image from the resource to be the background of the Program

There is no function to perform this operation Without shortcomings and problems

And also in the C++ 6 no function of this operation Without shortcomings

You can use this message with the library's GDIPlus And with many types of images

Not Supported by the GUICtrlCreatePic function Such as this example

I translated this reply And I'm sorry if it contains clerical errors
