ActiveQt Word Automation sample

I've found this question on StackOverflow requesting advice for creating a Word document from scratch (as opposed to opening / modifying) an existing one, from a Qt application. The user wants to use raw QAxObjects and dynamicCall() to do so, in line with other answers on the same site, but I know that there is a better way of automating Office applications: importing the object model from the MS Word COM type library into the C++ project. This is a sample template of the proposal, that is very similar to the Qutlook Example for the Outlook application. You can extrapolate the technique to Excel and PowerPoint if you want.

It is a command line project with only two files: the Qmake project file and 'main.cpp'. The project file uses the utility dumpcpp.exe to generate the header and source files from the type library.

DUMPCPP=$$absolute_path("dumpcpp.exe", $$dirname(QMAKE_QMAKE))
TYPELIBS = $$system($$DUMPCPP -getfile {00020905-0000-0000-C000-000000000046})

To obtain the Guid of a type library, you may want to use the 'oleview.exe' utility to explore the libraries installed in your Windows box.

The main() function #includes the generated header "MSWORD.h", creates a new document, populates its contents with two text lines, and saves this document twice: the first time in the modern DOCX format, and again in the DOC format compatible with Word 97/2003.
