Problems with COM

[Roger Upole]

What does the SearchDocuments function look like ?
Couldn't you just create the object in that function, and
then return object.count to the calling function ?

BTW, resultSpace=win32com.client.Dispatch actually
assigns the Dispatch function to resultspace, so you are
passing a function rather than a COM object.
