detach header source?

[christopher.allen]

In Word 2000/2003 VBA, I'm processing mail merge docs that may or may
not have header and data sources already attached. I'm attaching other
data sources that contain their own header info, so I want to remove any
already-attached header source.

Is there a way to do this? Calling OpenHeaderSource with "" gives a
runtime error. Can't set HeaderSourceName as it's read-only. Thanks!

Try setting .MainDocumentType to wdNotAMergeDocument (of course you lose
all the data source connection info. but it looks as if you are doing that
anyway).

Based on your tip (thanks!) I looked at the online doc for
MainDocumentType, which says this:

"If you set this property for a document that's already a main document,
the attached data source is removed."

It doesn't specify what to set it to. Since my code already sets it to
wdFormLetters after opening, I verified that this really removes the
data source, plus it also removes the header source.
