ParentCatalog Property Example (VB)

ParentCatalog Property Example (VB)

The following code demonstrates how to use the ParentCatalog property to access a provider-specific property prior to appending a table to a catalog. The property is AutoIncrement, which creates an AutoIncrement field in a Microsoft Jet database.

Sub CreateAutoIncrColumn()

    Dim cnn As New ADODB.Connection
    Dim cat As New ADOX.Catalog
    Dim tbl As New ADOX.Table

    cnn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
        "Data Source= c:\Program Files\" & _
        "Microsoft Office\Office\Samples\Northwind.mdb;"
    Set cat.ActiveConnection = cnn

    With tbl
        .Name = "MyContacts"
        Set .ParentCatalog = cat
        ' Create fields and append them to the new Table object.
        .Columns.Append "ContactId", adInteger
        ' Make the ContactId column and auto incrementing column
        .Columns("ContactId").Properties("AutoIncrement") = True
        .Columns.Append "CustomerID", adVarWChar
        .Columns.Append "FirstName", adVarWChar
        .Columns.Append "LastName", adVarWChar
        .Columns.Append "Phone", adVarWChar, 20
        .Columns.Append "Notes", adLongVarWChar
    End With

    cat.Tables.Append tbl

    Set cat = Nothing

End Sub
