[flyhigh]

ive been staying away of dx stuff because it messes up my desktop,does dx use low resolution or something?
and is there away to backup your desktop with vb6 for future bad happingings?

It shouldnt mess up your desktop. When you make a dx app and have it fullscreen, exiting out should put the screen resolution back the way it was without moving your desktop icons. It might depends on what OS you are using too. I'm using Windows 7 Pro 64 bit and it doesnt affect my desktop nor on Windows XP Pro 32 bit. Windows 98 and below maybe. It'll also depend how you are exiting out of your DX program. For example in this, it should exit out fine:

Also you could try updating your video drivers, or even on your desktop Arrange Icons By Name / Type and see if itll still affect it
