This works, but still leaves the problem of the corrupting Window title bars (for non-resizable forms). Is there a workaround for this, and will this be fixed in SP2?

Hi Calvin,

vfp9 on vista is also not painting the NonClientArea of a form correctly if the form isn't sizable (as Dominic mentioned). The problem also occurs after the form was partly moved outside the visible area, e.g. below the lower border of the vfp screen.

I assume vista is blocking some window message. When you run vfp as administrator (e.g. from the context menu) the problem is gone.

So, is there a way around it, too?

Hi,

Just add this code to your INIT event of your form:

LOCAL lnBorderStyle

lnBorderStyle = this.BorderStyle

ACTIVATE WINDOW (THIS.NAME) IN SCREEN NOSHOW

this.BorderStyle = lnBorderStyle

Hi Ricardo,

thank you for this tip. It turned out that it even works without setting BorderStyle again after ACTIVATE WINDOW.

Just in case someone needs a solution for forms shown in top level form, too, take a look at http://www.bingo-ev.de/~mw368/vfp9_vista.html

DECLARE integer GdiSetBatchLimit IN WIN32API integer

GdiSetBatchLimit(1)

The above indeed works perfectly (at least in Windows Vista Home Premium) in AutoComplete functions, however, complying/deploying SP2 by itself did not prevent the reported display errors "showing multiple selected items"... The two magic lines were required in order to avoid this display problem.

On a related issue, is there any reason why on Aero enabled (on Vista with Aero) floating forms (so those with showwindow>0) the closing 'X' (top right) is showing as enabled (red in colour) at all times, even if the closable property is false. You can't click it, but it's still red. All forms with showwindow=0 still have old style smaller 'X' boxes, and they correctly display Red or Grey to show enabled or Disabled status.

I've already applied the Combo Box and Graphic refresh fixes for Vista to the forms, but they still have the problem.

Anyone have any ideas?

This combobox bug is still not solved in 2009!
