Ensure that you are treating the result as a string (actually a
widestring).

Yes, I receive the result using a BSTR
I debug the programe and find that visio seem not to allowe any program to
call the function, a error from assert(hr) will be pop up.
what happened?

It's a property, not a function - remove the () after GetVersion.
