code to change screen resolution?

[pronate]

Hi,

I design my GUI in 1024x768 resoultion, and because this is goping to be a multi-user thing, some of my User's PCs are 800x600 and, belive it or not, some are 640x480. When they open the database, its not very pretty.

How do i please everyone?

this is the code that I use though you will need to change the calculation at the end to resize downwards
