VB.NET is different than Word VBA, which is what I do (barely, but I do
it!). The Dev Handbook has all the objects, methods, and properties listed.
It's intended for use within Word's VBA, which is similar to but not the
same as VB or .NET. I'm not knowledgeable enough to tell you all the
differences, except that VBA is application-specific, and not used as a
stand-alone program. I am not well-versed in any aspect of VB, but I have
heard that VB (and .NET, too, I presume) can call Word and then use its
methods, etc.
If you're exploring VB and .NET, you might be better at
microsoft.public.vb.general.discussion. Sorry I couldn't help more.
