MORE INFORMATION
To obtain the connection string required by the Microsoft Query, call
ODBCLOGON by initiating a DDE session to a query that is currently
logged into a data source and perform a DDE request of the
connectionstring item:
- Start Microsoft Query and log on to a data source.
- In Microsoft Query, create a query (QUERY1).
- Start Microsoft Excel and create one of the following macros.

provided 'as is' and Microsoft does not guarantee that they can be used in
all situations. While Microsoft Support professionals can help explain the
functionality of a particular macro, they will not modify these examples to
provide added functionality, nor will they help you construct macros to
meet your specific needs. If you have limited programming experience, you
may want to consult one of the Microsoft Solution Providers. Solution

Sub get_connection()
' Open a DDE channel to MSQuery and return the channel number
chan = Application.DDEInitiate("Msquery", "Query1")
' Return the array that contains the connection string
connect = Application.DDERequest(chan, "ConnectionString")
' Terminate the DDE channel
Application.DDETerminate chan
End Sub
The DDERequest method returns the array "connect" that contains a
valid connection string that can be used by the ODBCLOGON command in
order to connect through a DDE control.
NOTE: If you are using Microsoft Query 97, you must modify the line that
initiates the DDE channel. This line must include the correct name for the
query. In Microsoft Query 97, the query name is similar to "Query 1 from
<Data Source Name>." For example, if the data source that the query uses is
named "My DataSource," change the DDEInitiate line to the following:
chan = Application.DDEInitiate("Msquery", "Query 1 from My DataSource")
Microsoft Excel Version 4.0 Macro Example
Microsoft provides macro examples for illustration only, without warranty
either expressed or implied, including but not limited to the implied
warranties of merchantability and/or fitness for a particular purpose.
This macro is provided as is and Microsoft in no way guaranties that the
following code can be used in all situations and will not support
modifications of the code to suit specific customer requirements.
=SET.NAME("CHAN",INITIATE("MSQUERY","QUERY1"))
=SET.NAME("Connect",REQUEST(CHAN,"CONNECTIONSTRING"))
=TERMINATE(CHAN)
=RETURN()
The defined name CONNECT will contain a valid connection string that
can be used by the ODBCLOGON command in order to connect through a DDE
control.
NOTE: If you are using Microsoft Query 97, you must modify the line that
initiates the DDE channel. This line must include the correct name for the
query. In Microsoft Query 97, the query name is similar to "Query 1 from
<Data Source Name>." For example, if the data source that the query uses
is named "My DataSource," change the DDEInitiate line to the following:
=SET.NAME("CHAN",INITIATE("MSQUERY","Query 1 from My DataSource"))
