For the controls to work, distribute and register Custom ActiveX.ocx files on the user systems. (The RoboHelp license allows you to distribute these controls.) By default, the controls are at C:\Program Files\Adobe\Adobe RoboHelp [version]\Redist.
1)Insert the cursor in the topic where you want to place the control.
3)Select the ActiveX control to add and click OK.
4)Double-click the ActiveX control to edit its appearance and properties. HTML Help doesn't support all ActiveX controls, and some controls don't have properties dialog boxes.
