Setting the MDI container background picture method

Previously, when setting the background of an MDI form, the following code was used to implement: (set IsMdiContainer to False)
To create an MDI container manually
Mdiclient mic = new Mdiclient ();
Mic. Dock = DockStyle.Fill;
Mic. BackgroundImage = Image.FromFile ("Bg.bmp");
Today I stumbled across a simpler approach:
Set the backgroundimage of the form to the background image you want.
If the form is an MDI container, the background picture is automatically loaded as the MDI container background.
Since the image is directly using backgroundimage, the image scaling mode is of course the same,
Do not believe that you set a backgroundimagelayout, see the effect of it, hehe.
Note: This method is feasible on VS2005 and VS2008.
