VB与Access数据库连接通过在模块中定义连接函数实现，具体代码如下：
Public cn As New ADODB.Connection
Public rs As New ADODB.Recordset
Public Function ConnectToServer() As Boolean
On Error GoTo ConnectErr
cn.Provider = "sqloledb"
cn.Properties("data source").Value = "KJ-A96E6B
cn.Properties("initial catalog").Value = "student"
cn.Properties("Integrated Security").Value = "SSPI"
cn.ConnectionTimeout = 30
cn.Open
ConnectToServer = True
Exit Function
ConnectErr:
ConnectToServer = False
MsgBox "错误代码:" & Err.Number & vbCrLf & "错误描述:" & Err.Description, vbCritical + vbOKOnly, "连接错误"
End Function
Public Function DisConnect() As Boolean
If cn.State = adStateOpen Then
cn.Close
End If
DisConnect = True
End Function
Public Sub crs(ByVal strsql As String)
On Error GoTo err1
Set rs = Nothing
rs.Open strsql, cn, adOpenDynamic, adLockOptimistic, -1
Exit Sub
err1:
MsgBox "错误信息:" & Err.Number & vbCrLf & _
"错误描述:" & Err.Description, vbCritical
Call DisConnect
End
End Sub
