You can do this one of two ways. One is by using ActiveX calls. You can either use ActiveX Automation to make Word open up by itself, or you can use ActiveX containers to display your document on LabVIEW's front panel.
You can also purchase the Report Generation Toolkit for Microsoft Office which makes this much easier. You can but this from NI. It provides VIs which open, modify, and save Word documents. It's also much easier to use than straight ActiveX calls.
