'----------------------------------------------------------------------------
Private Sub Form_Load()
Dim adoCN  As New ADODB.Connection  '定义数据库的连接
Dim strCnn  As New ADODB.Recordset
Dim rstSchema As New ADODB.Recordset
Dim I As Integer
  str1 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\Northwind.MDB;Persist Security Info=False"
  adoCN.Open str1

  Set rstSchema = adoCN.OpenSchema(adSchemaTables)

  Do Until rstSchema.EOF
    If rstSchema!TABLE_TYPE = "TABLE" Then
      out = out & "Table name: " & _
        rstSchema!TABLE_NAME & vbCr & _
        "Table type: " & rstSchema!TABLE_TYPE & vbCr
      I = I + 1
    End If
    rstSchema.MoveNext
  Loop
  MsgBox I
  rstSchema.Close

  adoCN.Close
Debug.Print out
End Sub

方法二:

Access 系统表 MsysObjects 包含了数据库对象列表。尽管未在文档中记载,你仍可通过查询它来获取你想要的。但是默认情况下无法操作系统表,必须手动设定权限收才能查询系统表。

请参考以下动画:如何获取对msysobject的操作权限

警告:不要修改任何ACCESS系统表,否则会出现不可意料的情况.

使用下列 SQL 语句来获取你想要的

查询:

SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (MSysObjects.Type)=5 ORDER BY MSysObjects.Name;

窗体:

SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (MSysObjects.Type)=-32768 ORDER BY MSysObjects.Name;

表:

SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (Left$([Name],4) <> "Msys") AND (MSysObjects.Type)=1 ORDER BY MSysObjects.Name;

报表:

SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (MSysObjects.Type)= -32764 ORDER BY MSysObjects.Name;

模块:

SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (MSysObjects.Type)= -32761 ORDER BY MSysObjects.Name;

宏:

SELECT MSysObjects.Name FROM MsysObjects WHERE (Left([Name],1)<>"~") AND (MSysObjects.Type)= -32766 ORDER BY MSysObjects.Name;
