Hide a form's taskbar button without using WS_EX_TOOLWIN

Question

I need to hide a Windows form from the taskbar but I can\'t use WS_EX_TOOLWINDOW because I need the system menu and min/max buttons on the form\'s title bar.

Answer 1

Thanks to Stu for putting me on to the answer so quickly. In my case I had to manually add the owning form's handle into the CreateParams, but that may not be necessary in other/normal cases.

procedure TfrmWord2Site.CreateParams(var Params:TCreateParams);
begin
  inherited CreateParams(Params);
  Params.WndParent := <your owner form>.Handle;
  Params.ExStyle := Params.ExStyle and not WS_EX_APPWINDOW;
end;
