Dynamically set showInTaskbar property

Hi,

I tried to place a from in the system tray, in the form_resize event, I set the form showInTaskbar property to false, however, this doesn't have any effect at all, the form is always shown in the taskbar. The form can be hidden from the taskbar if the showInTaskbar is set at design time in the Visual Designer. Can anyone shed some light please? BTW, I use OpenEdge 10.2B.

Thanks
