ActiveX inside InTouch

Hi,

I am trying to use the ActiveX controls, specifically the S7 ComboBox, that InTouch offers and I am having a tough time understanding the lingo inside the Events area.

Does anybody know where to find definitions of these events, for example, hWnd? I have never used ActiveX controls before in InTouch or anywhere else to be honest.

Any ideas as to where to find definitions or a good place to find examples of ActiveX controls done in InTouch would be greatly appreciated.

Thanks for the time,
Max
