Broadly speaking it should be possible to do this in much the same way that
it worked with Office 2000. The document and the query should be the same or
similar, but
a. Word nowpops up an additional question when you open a mail merge
document that is already attached to its data source. If you are opening the
document programmatically, the equivalent is that Word may fail to open the
data source if you have not made a modification to the user's Windows
Registry (in this case, the "user" could be ASP.NET, depending on what
you're doing) - see
http://support.microsoft.com/kb/825765/en-us
b. If you are attaching the data source programmatically using Word's
OpenDataSource method (this is likely, but it is also possible that the
document has been saved with the data source attached) then you will
probably need to modify the code a bit. With WOrd 2000 you would have been
using ODBC to connect to SQL Server and you would have had something like
objDocument.MailMerge.OpenDataSource _
Name:="", _
Connection:="DSN=name of the SQL Server DSN;other connection info;", _
SQLStatement:="SELECT * FROM whatever"
or possibly
objDocument.MailMerge.OpenDataSource _
Name:="pathname of a dsn file.dsn", _
Connection:="FILEDSN=pathname of a dsn file.dsn;other connection info;", _
SQLStatement:="SELECT * FROM whatever"
in Word 2003 you will almost certainly need to add an extra parameter,
Subtype:=wdMergeSubtypeWord2000
FWIW in Word 2003 the default connection method has changed from ODBC ato
OLE DB and you might want to change the OpenDataSource to reflect that. In
that case, you need a .udl file or .odc instead of that DSN, a different
connection string, and to alias the table names in the SELECT statement. (If
you search this group in Google groups for Peter Jamieson SQL Server SELECT
you may find some examples. The main advantage of using OLE DB is that it
deals with Unicode field types correctly.
There are other changes in the Word user interface that may affect what
users see and usabilty in general, but I suggest you start by getting the
connections to work.
