You can add any ActiveX control that is registered on your authoring system to the topics in your projects.
From the Insert menu, select ActiveX Control.
From the list of ActiveX controls, select the one that you want to add, and then click OK.
To edit the appearance and properties of the ActiveX control, double-click it and change the available settings on the properties dialog.
Note: In order for ActiveX controls to work on end users' systems, they need to be copied on their systems and registered. (ActiveX controls are not included in compiled .CHM files.) For further information, see Registering ActiveX controls.
