测试使用 ADOX方 便的查询表和字段
添加2个列表框，1个按钮
'引用微软 ADO Ext.2.X for dll and Security
Dim cat As ADOX.Catalog
Dim cnn As ADODB.Connection
Dim tbl As ADOX.Table
Private Sub Command1_Click()
On Error Resume Next
For Each tbl In cat.Tables
'如果是sqlserver数据库，则变成If Left(tbl.Name, 3)"sys"
If Left(tbl.Name, 4)"MSys" Then
List1.AddItem tbl.Name
End If
Next
End Sub
Private Sub Form_Load()
Set cnn = New ADODB.Connection
Set cat = New ADOX.Catalog
cnn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=F:\csdn_vb\database\article.mdb"
'cnn.Open "Provider=SQLOLEDB.1;Persist Security Info=False;User ID=sa;Initial Catalog=northwind;Data Source=yang"
Set cat.ActiveConnection = cnn
End Sub
Private Sub Form_Unload(Cancel As Integer)
Set cat = Nothing
Set con = Nothing
End Sub
Private Sub List1_Click()
Dim fld
Dim intfield As Integer
List2.Clear
intfield = cat.Tables(List1.List(List1.ListIndex)).Columns.Count
For i = 0 To intfield - 1
Set fld = cat.Tables(List1.List(List1.ListIndex)).Columns(i)
List2.AddItem fld.Name & " " & fld.Type & " " & fld.DefinedSize
Next
End Sub
