Hi,

ok - I understand what you mean now. I thought of resizing a form and a contained pageframe that needs to be resized when the form is being resized. For this task I'm always resizing the pageframe with a ratio calculated with PageHeight/PageWidth and making sure that these properties are not less than zero. Trying to make a pageframe smaller in height than the tabs' height results in an error.

Hmmm ... I think doing ...

thisform.pageframe1.Height - thisform.pageframe1.PageHeight

worked for me some time ago. Yes, just made a test (VFP7SP1). Works well. Another idea, if the above code doesn't work for you:

LOCAL lnHeightTabs

lnHeightTabs = thisform.pageframe1.PageHeight

thisform.pageframe1.tabs = .f.
lnHeightTabs =  thisform.pageframe1.PageHeight - lnHeightTabs
thisform.pageframe1.tabs = .t.

MESSAGEBOX( lnHeightTabs )

The first code returns 30 in my test, the second 26. It seems that you should add some extra pixels for the borders.

HTH,
Armin

>>how about only working with PageHeight? If you specify the minimum pageheight everything should work ok. Or do you have a special need to specify the minimum height of the pageframe itself?
