Hi Delsolice
The best place to get help with the "how do I do it in Word" is the newsgroup for the application + topic. There's a word.mailmerge.fields newsgroup; you'll find a link in the forum's
Please Read First message. They probably can't give you C# code, but the basic code you need won't be any different from the VB(A) that prevails there.
FWIW, when a Word 2003 mail merge document is opened via the object model that link to the data source should be broken. This is a Security measure.
So your code will probably need to hook up to the data source AND set the query.
the best way to get the basic syntax is to record the actions in a VBA macro. As Word's mail merge data connection is a bit "finicky", you certainly need to record a macro to get the parameters for the OpenDataSource method. If the query is fairly simple, you can include the SELECT statement when you hook up to the data source.
For any more detailed support, I recommend the newsgroup, as it's been quite a while since I worked with mail merge in any depth.
