Do you want to add tooltip support to every single UI control on the screen? If so, you have come to right place. I will show you how to add tooltip support for "Group" control. The same technique can be used for other controls. Afterwards, you can start setting psToolTip for the "Group" control.
P.S. It is imperative to set pbUseFormWindowHandle to False unless the control itself supports Form_Window_Handle. See Form_Window_Handle for details.
P.P.S. Huge shoutout to DaveR for trying out the code and pointing out the previous code didn't work. (It was the missing Page_Object/Page_Delete methods).
