PRB: Error Returned When Attempting to Modify JET Database

MORE INFORMATION

The following example will open a database (use Nwind.MDB), open a table within that database, and then attempt to create a relation using the open table.

Steps to Reproduce Behavior

1. Create a Standard EXE project in Visual Basic. Form1 is created by default.
2. Under Project/References, add "Microsoft DAO 3.51 Object Library."
3. Add a CommandButton to Form1 and add the following code under the Click event:

         Dim Fld as Field
         Dim Tbl as Recordset
         Dim Rel as Relation
         Dim db as Database
   
         Set db = OpenDatabase("nwind.mdb", True)
   
         Set Tbl = db.OpenRecordset("employees", dbOpenTable)
         ' Note that employees table is used below in creating the relation.
         ' Uncommenting the line below allows the code to work properly.
         ' Tbl.Close
   
         Set Rel = db.CreateRelation("myrel")
         Rel.Table = "Employees"
         Rel.ForeignTable = "Orders"
         Set Fld = Rel.CreateField("EmployeeID")
         Fld.ForeignName = "EmployeeId"
         Rel.Fields.Append Fld
   
         ' eError will occur on next line.
         db.Relations.Append Rel
   
   						

4. Uncomment the line for closing the recordset and note the relation is created and added to the database without error.
