The original question is from a month ago but hopefully this will be helpful still to you.
You can definitely control NetMeeting using ActiveX and LabVIEW. All you need is to have NetMeeting and its ActiveX control installed on your machine. Then use the following method to get the NetMeeting controls on your LabVIEW VI Front Panel.
1. Place an ActiveX Container on the Front Panel (
Controls Palette >> ActiveX >> Container)
2. Right click inside of the container and select Insert ActiveX Object...
3. Select from the list the ActiveX Control named NetMeeting.
The container will then have an instance of NetMeeting in the ActiveX container. I followed these exact steps above and created this VI which is just a NetMeeting control i
n an ActiveX container.
Hopefully this information is helpful. I created the example in LabVIEW 6i.
