It's not how I do with SendInput, which I may be confusing here with SendMessage methods. -- ..NET: It's About Trust! http://vfred.mvps.org Customer Hatred Knows No Bounds at MSFT ClassicVB Users Regroup! comp.lang.basic.visual.misc Free usenet access at http://www.eternal-september.org

Hmmmm, I think you'll need to attach to the other thread's input queue, maybe?
