screen res

[R LAWSON]

Hi everybody
I recently created a vb app. using a desktop resolution of 1024x768. I made the form to fit the page in a windowed state but when I installed on a 800x600 res the form was bigger than the screen. Is there a way of getting the form to adjust to whatever the users current res is ?
Thanks!

The following works in 98% of situtations but it has a few minor bugs. You can try it and see if your situtation works.
Only problem is it retains the original size so you must design your form for the smallest size and then the code will stretch it to the largest. It doesn't go backward.
Will not help the current situtation but it may help you in a future endevor.'resize as per secreen resolution

'create a class module and put this code into it
