>I am working on a form splitter where user can drag it left and right to increase the size of the window (and at the same time increase or decrease the left pane). I don't want to increase the width of the form such that the right edge would go beyond the available screen/desktop. How can I determine the max width for a form and given desktop and the resolution?

Desktop is in SYSMETRICS as far as I remember
VFP is _SCREEN.width

Then you need to do some math with thisform left, thisform width and desktops width

Anyway:
It is usual that the splitter changes the ration of forms elements, not the overall width of a form
Try windows explorer, or VFP's property dialog.
