Visual Basic Screen Resolution Changes

The coordinates for the pixel detection, mouse coords seem to be ok. I am not sure how to word this perfectly.

I take it back on a test computer, the mouse and pixels are off.

Can you explain what you are trying to do, whats not working, and then post the code for that part of the application?

If it helps, my screen resolution is 1680 x 1050.

Other system needed to work on is 1056 x 825

Here is the code, my computer uses 1680 x 1050 that I used to develop this program on. The host computers use 1056 x 825. Rather than change my display, is it possible to just have the program do the changes?

Where you at Idle_Mind... I have been searching still trying to find a good resolution to this but no luck so far.

Sounds good, I will be here when you return ;). I have my daughters 7'th bday today, so we going over wife's parents for cake / icecream ;).  I will be back later as well.

Idle, thanks again! Once I get more time I will look further into it. I did some pokeing around and found that this will work just need to play with it. If I find any problems I will post another questions. Thanks Man

You'd use things like FindWindow()/FindWindowEx() and/or EnumWindows()/EnumChildWindows() instead.
