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
