Hello Nick,
From your post, my understanding on this issue is: you want to know what
the host application is in your program. If I'm off base, please feel free
to let me know.
All Office COM add-ins need to realize the interface: IDTExtensibility2, in
which the method OnConnection needs to be implemented. The method has a
parameter 'application' which points to your host application object,
therefore, we can know what the host application is by getting the type of
that pointer. For instance:
In C++, we can try to query Word._Application interface with
IDispatch.QueryInterface method, if it succeeds, it is a Word, otherwise,
try to query Excel._Application to determine whether it is an Excel
application.
In C#, the statement 'if (application is Word.Application)' will help to
determine whether is a Word application. 'application.GetType().FullName'
will also return 'Microsoft.Office.Interop.Word.ApplicationClass' to
indicate that the current host application is a Word.
In VB, please use the statement: 'If TypeOf application Is Word.Application
Then' to determine the host application.
Please let me know if you have any other concerns, or need anything else.
Sincerely,
Jialiang Ge (
