DAO访问数据库

用这个，我以前用DAO的时候写的：

Public Function ExistsTable(TName As String) As Boolean
Dim dbAccess As Database
Dim Test As String

On Error Resume Next

Set dbAccess = OpenDatabase(App.Path & "\dbdevice.mdb", False, False)
' 该名字在表名中是否存在。
Test = dbAccess.TableDefs(TName).Name
If Err <> 3265 Then
ExistsTable = True
Err = 0
End If
dbAccess.Close
End Function

ADOX也可以
Dim cnn As New ADODB.Connection
Set cat = CreateObject("ADOX.Catalog")
cnn.Open "..............;"
Set cat.ActiveConnection = cnn
For Each tb In cat.Tables
Debug.Print tb.Name
Next
