    The reason you're not seeing the query is because you're not naming it.

    Put a query name in:

    Set qdfNew = dbsTemp.CreateQueryDef(strQueryName)

    I put the name in there and now it shows up in my TempDB. However,
    there are still two problems. First, if I open up the TempDB I can see
    the query in the db window, but if I try to open it a "Select Data
    Source" dialog box opens instead of the query result. What is going on
    here? Second, I still cannot figure out how to connect it to the
    CurrentDB so that I can see it in the CurrentDB's database window (like
    I can with the temp tables). Thanks again for your help.

    I don't believe your Connect property is correct (you're missing a
    semi-colon before the keyword DSN). However, what's strTempDatabase? If it's
    a Jet database (i.e. an MDB), you can't use ODBC to connect to it from
    Access)

    You cannot create the equivalent of linked queries. In other words, there's
    no way for you to see it in your front-end.
