You can use functions that go along with the ActiveX controls to do what you are wanting to do. For example, to stop a counter, you could use the function CWCounter1.Stop. For a complete list of functions to use, right click on the ActiveX control and select Help. This will guide you to a list of all the functions. Also, the manaul I've attached will give you a lot of info on how to stop and reset the controls in chapter 6.
