The scrollbar should appear if you have CONTROLS beyond the visible area of the Form itself.

The picture doesn't quite show us the whole story, but it looks like the form is big enough to hold the controls, but the Form is actually extending beyond the edges of the SCREEN which is a completely different scenario.

Scrollbars won't appear when the form is paritally off the screen...

Ok...are you using AutoScroll() or did you physically add a VScrollBar to your Form?

Gotcha...a VScrollBar has ABSOLUTELY NO INHERENT ability to scroll the the form or anything else.  It is simply a slider bar that allows the user to pick a value using the arrows and the slider.  To make a VScrollBar actually scroll the form you would need to manually add code that detects the scrolling events and then changes the contents of your form.

The "correct" way to allow scrolling on a Form is to set the AutoScroll() property to True and then the vertical/horizontal scrollbars will automatically appear if controls are placed OUTSIDE the visible area of the form.

It's not there.  Get rid of the VScrollBar!...

Set the AutoScroll() Property of the FORM ITSELF to True.

Don't quite understand your last statement chokka....could you re-word that a different way?

If you make the form smaller then the scrollbars will appear and the form may fit on the screen....?
