here code can taking screen shot , automatically saving it. option 1.

    dim screenshot new bitmap(screen.primaryscreen.bounds.width, screen.primaryscreen.bounds.height, pixelformat.format32bppargb)      dim g = graphics.fromimage(screenshot)     g.copyfromscreen(0, 0, 0, 0, screenshot.size)     g.dispose()      screenshot.save("c:\test.bmp") 

you put in timer or , add date or incremented number end of file name.
