proe VB.net 以指定配置文件夹启动

如题   我在开发的时候

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click        Dim cAC As CCpfcAsyncConnection
        cAC = New CCpfcAsyncConnection
        asyncconnection = cAC.Start("E:\PTC\proeWildfire 4.0\bin\proe1.bat", "E:\work")
    End Sub
想让程序以E:\work 文件夹启动
但是 上面的代码不行。
有知道的吗？
