LabVIEW has objects called activeX containers and activeX automation references. The difference between the two is that a container sits on the front panel and a reference does not. I have not been able to find the control for MS Word that allows me to put Word in a container. I do not believe that Microsoft allowed for this ablity. As a workaround. you might put Internet Explorer in the container and direct it to open a Word document. This somehow tranforms Internet Explorer into a Word like program. As for the automation reference, there is a MS Word control on my computer that allows launching Word and exposes features like open, spell check, ect.
Look at the activeX examples that are shipped with LabVIEW to see how activeX is used and configured.
Open LabVIEW 6.1 >> help >> find examples >> communicating with external applications >> activeX. As far as making specific calls goes, you are on your own. The problem is that NI does not have the specific activeX information about third party programs. For Microsoft products, you can search msdn.microsoft.com.
