Flash as background on vb.net

Question

Does anyone know how to make a flash .swf act as a background on the main form? If I have multiple forms open and then close each of those forms, I need the flash to still be shown on the screen as if its a background.

I have added the flash component from the COM and know the following code is used to call a .swf.
Call AxShockwaveFlash1.LoadMovie(0, "c:\vbflash\test.swf")
