This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. The following steps demonstrate how to create and use the sampleListAllTables() function.
  1. Start Microsoft Access and open the sample database Northwind.mdb.
  2. Insert a new module.
  3. On the Tools menu, click References, and select the following references if they are not already selected (checked):
    • Microsoft ActiveX Data Objects 2.1 Library
    • Microsoft ADO Ext. 2.1 for DDL and Security

  4. Type the following code in the module:
    Function ListTables(fld As Control, id As Long, row As Long, _                       col As Long, code As Integer)                          Dim cat As New ADOX.Catalog   Dim tbl As ADOX.Table   Static tbls(256) As String   Static Entries As Integer   Dim ReturnVal   ReturnVal = Null   Select Case code         Case acLBInitialize         ' Initialize database.         cat.ActiveConnection = CurrentProject.Connection         Entries = 0         For Each tbl In cat.Tables            If tbl.Type = "TABLE" Then               If tbl.Name <> "dtproperties" Then                  tbls(Entries) = tbl.Name                  Entries = Entries + 1               End If            End If         Next tbl         ReturnVal = Entries      Case acLBOpen               ' Open.         ReturnVal = Timer        ' Unique ID number for control.      Case acLBGetRowCount        ' Number of rows.         ReturnVal = Entries      Case acLBGetColumnCount     ' Number of columns.         ReturnVal = 1      Case acLBGetColumnWidth     ' Column width.         ReturnVal = -1           ' Use the default width.      Case acLBGetValue           ' Get the data.         ReturnVal = tbls(row)      Case acLBEnd                ' End.         For Entries = 0 To 256            tbls(Entries) = ""         Next   End Select      ListTables = ReturnValEnd Function					
  5. On the File menu, click Save databasename.
  6. Create a blank new form that is not based on any table or query.
  7. Add a combo box control to the form.
  8. Set the RowSourceType property of the combo box to ListTables.
  9. View the form in Form view. Note that the combo box lists all the tables in the current database.
