Remove Focus?

I have a small winform that displays in the lower right corner of the screen (Sorta like MSN messenger email alert box) and whn it pops up i dont want it to have focus. I want to still be doing what i have been doing. Like if i am typing and this box pops up, i dont want it to take focus and stop typing, i want it to keep going, but have the box still visible. Any ideas?

I think you have to use SetWindowPos API with some Const flags but I can't remember which one . Do some search for that call , hopfuly you can find some examples .
