My app runs on a multi screen monitor. it showed a button on the 1st and 2nd monitor,so that when you click it it knows which monitor you clicked on. Then it calls a dll, but the dll always appear on the 1st monitor, center aligned. Even if i hard code the left property of the dll form, it still shows on the 1st monitor center aligned.

How can i make the dll form show on my specified left property?  (by the way, other forms aside from dll appears correctly either on second or first monitor)

I had this problem yesterday

I found no other (working) solution than to write a handler on the forms Activate event


var PosRect: TRect;
    FirstActivate: Boolean;

when you call your dll and display the form set it's coordinates (PosRect variable)

when the form is Activated set the coordinates :

procedure TDllForm.FormActivate(Sender: TObject);
begin
  if FirstActivate then
  begin
    FirstActivate:=false;
    SetBounds(PosRect.Left, PosRect.Top, PosRect.Right, PosRect.Bottom);
  end;
end;


I tried lots of ways with SetwindowPos from the calling process .. nothing worked
this was the only way I could get it to work
this also depends on the forms ParentWindow !
