I tried the following code to open a doc file in an MFC application.
CNiWordApplication word;
CNiWordDocument doc = word.OpenDocument("c:\\books.doc");
This worked fine for me. I tried this with Word 2003 and Measurement Studio 7.1
Try running one of the shipping examples. You can find examples for this under ..\MeasurementStudio\VCNET\Examples\Office\
Hope this helps.
