如何在 Access 2003 和 Access 2002 中创建 DSN 的连接到 SQLServer 对链接表

rs''// stServer: Name of SQL Server that you are linking to''// stDatabase: Name of the SQL Server database that you are linking to''// stUsername: Name of the SQL Server user who can connect to SQL Server, leave blank to use a Trusted Connection''// stPassword: SQL Server user passwordFunction CreateDSNConnection(stServer As String, stDatabase As String, Optional stUsername As String, Optional stPassword As String) As Boolean On Error GoTo CreateDSNConnection_Err Dim stConnect As String If Len(stUsername) = 0 Then ''//Use trusted authentication if stUsername is not supplied. stConnect = "Description=myDSN" & vbCr & "SERVER=" & stServer & vbCr & "DATABASE=" & stDatabase & vbCr & "Trusted_Connection=Yes" Else stConnect = "Description=myDSN" & vbCr & "SERVER=" & stServer & vbCr & "DATABASE=" & stDatabase & vbCr End If DBEngine.RegisterDatabase "myDSN", "SQL Server", True, stConnect ''// Add error checking. CreateDSNConnection = True Exit FunctionCreateDSNConnection_Err: CreateDSNConnection = False MsgBox "CreateDSNConnection encountered an unexpected error: " & Err.Description End Function注意 如果再次, 调用 RegisterDatabase 方法 DSN 更新。

若要调用 CreateDSNConnection 函数, 请代码， 它类似于之一以下代码示例在 Autoexec 宏中或启动窗体 Form_Open 事件中：

•	当您使用 Autoexec, 调用 CreateDSNConnection 函数, 并然后传递参数， 如以下所示从 RunCode 操作。 CreateDSNConnection ("(local)", "pubs", "", "")
•	当您使用启动窗体, 将代码， 它类似于以下以 Form_Open 事件。 Private Sub Form_Open(Cancel As Integer) If CreateDSNConnection("(local)", "pubs", "", "") Then ''// All is okay. Else ''// Not okay. End IfEnd Sub

注意 此方法假定通过使用 " myDSN " 作为 DSN 名称， 您已经创建链接 SQLServer 表 Access 数据库中。
