Hello S=E9rgio, There is a wonderful example that does exactly what you are asking. In the NI Example Finder, look for the =93ActiveX Event Callback for IE.vi.=94 I=92m not sure what ActiveX application you are using (this one is for Internet Explorer), but the principles are the same.
If this example doesn=92t help, or if I=92m not correctly understanding your issue, please post the software and versions you are using, the applicable portions of your code, and any other information that may help, and I=92ll be happy to look further into it. Have a nice day! Robert M Applications Engineer National Instruments
