VB.NET and word automation..

[minnn]

From a webform, i wish to get some data and use it to populate a word document that i have with merged fields (which were set up through mail merge feature).

So far i have been able to create a word object and open the document. Now i am stuck at the part where i import specific data on the webform to particular merged fields in the word doc. Data in the webform will be held in variables so i need to tell the application to match a particular variable to a particular merged field in the word doc, but how do i do this??

This is how far i have got:

'create an instance of the application  
        Dim wordApp As Word.Application
 
        'create new document
        Dim wordDoc As Word.Document
 
        wordApp = CreateObject("Word.Application")
 
        wordDoc = wordApp.Documents.Open(FileName:="c:\labeltemplate.doc")

please help
