Thanks for the help. As a further complication I needed to save in Word's filtered html format. The following code seems to work.

Qt Code: 
  1. //Start Word
  2. my_app = new QAxObject("Word.Application", this);
  3. QAxObject* my_docs = my_app->querySubObject("Documents");
  4.  
  5. //Open newDocName
  6. QVariant filename(newDocName);
  7. QVariant confirmconversions(false);
  8. QVariant readonly(false);
  9. QVariant addtorecentfiles(false);
  10. QVariant passworddocument("");
  11. QVariant passwordtemplate("");
  12. QVariant revert(false);
  13. QAxObject* doc = my_docs->querySubObject("Open(const QVariant&, const QVariant&,const QVariant&, const QVariant&, const QVariant&, const QVariant&,const QVariant&)", filename,confirmconversions, readonly, addtorecentfiles, passworddocument, passwordtemplate,	revert);
  14.  
  15. //Pull out active document object
  16. QAxObject* active_doc = my_app->querySubObject("ActiveDocument");
  17.  
  18. QVariant newFileName(fileNameString);
  19. QVariant fileFormat(10); //Saving as filtered html
  20. QVariant LockComments(false);
  21. QVariant Password("");
  22. QVariant recent(true);
  23. QVariant writePassword("");
  24. QVariant ReadOnlyRecommended(false);
  25.  
  26. active_doc->querySubObject("SaveAs(const QVariant&, const QVariant&,const QVariant&, const QVariant&, const QVariant&, const QVariant&,const QVariant&)",    newFileName, fileFormat, LockComments, Password, recent, writePassword, ReadOnlyRecommended);
