我有段VB.NET的程序,数据库老连不上,各位大虾帮忙:
Public Sub ConnectionSysDB(ByVal DBName As String, ByVal PW As String, ByVal OpenClose As Boolean)
Dim ConnectSuperPay As New ADODB.Connection()
Dim StrConnectString As String
Dim DbPathAndName As String
DbPathAndName = SuperPayPath + "/database/" + DBName '确定数据库的路径和文件名
StrConnectString = "Data Source=" + DbPathAndName + ";""Jet OLEDB:Database Password=" + PW + ""
StrConnectString = "Provider=Microsoft.Jet.OLEDB.4.0;" &
_
"Data Source=" + DbPathAndName + ";""Jet OLEDB:Database Password=" + DatabasePassWord + ";"



' MsgBox(StrConnectString)
If OpenClose = True then
With ConnectSuperPay
.CursorLocation = adUseClient
.Provider = "Microsoft.Jet.OLEDB.4.0"
.Open(StrConnectString)
End With
else
ConnectSuperPay.Close()
End If
End Sub
