Is the yellow square "dynamic"?...that is to say does it need to be moved around?

Move it via CODE or let the USER move it around?
Do you need assistance with moving or sizing the rectangle?
Of course, disappearing simply involves not calling the highlight code.

I need the user to be able to move it then I will save the coordinates in a database and have the code move it there automaticly
I also need to turn the highlite on and off and back on again at different times
and finaly although this is my last priority in case you dont have time for all my questions I would like the user to be able to resize the box

dear Idle mind
I would prefer to use some code you gave me before at
http://www.experts-exchang
could you tell me how to progromaticly change the size and locations of a rectangle I drew with that code
I prefer it over the use of forms
Thank you

If you want to use that code then you just need to use a Color with an Alpha channel set as MTEXX demonstrated earlier:
Dim highlightColor As Color = Color.FromArgb(196, 255, 255, 0)
Dim highlightColor As Color = Color.FromArgb(196, 255, 255, 0)

thank you I am laying these rectangles over a very large bitmap that scrolls how can I get the rectangles to cover the same part of the bit map in case I scroll it up or down?
In other words how can I get the rectangle to scroll with the image?

I'm on vacation at the moment and won't be back home until this weekend. I'll play with it then...
