Been a while since I came here... I know that no one remembers me, so forget it

For one of my projects, I want to create a little program that would somewhat work like the Companion in Office 2000. In order to do that, I'll need to know a few things. I'm sure that some of these are pretty easy, but others will be painful, I'm afraid...

1- How do a make a form so it always stays on top of the others?
2- How can I drag a form to any location of the screen just by dragging it (not using the title bar)?
3- How can I make a form "transparent", so only the picture itself shows?

That's it for now... I'll probably come back for more later. Any help would be much appreciated
