VB.NET 调用外部程序有关问题

VB.NET 调用外部程序问题
Me.OpenFileDialog1.ShowDialog()
  Dim j As String = OpenFileDialog1.FileName
  Process.Start(j)
为什么我这样程序是可以调用EXE的，
 Dim i As String = "D:\wanghc\调试中的程序\1exe\1exe\bin\Debug\Demo\OnlineFaceRec.exe"
Process.Start(i)
这样就不行了呢，程序一闪而过，我想不明白，用别的程序试是可以的，一开始我以为是那个EXE的问题，可是第一种方法还可以调用，请高手帮忙

[解决办法]

VB.NET code

    Public Function ExecuteCmd(ByVal cmd As String, ByVal CreateNoWindow As Boolean)        Dim startInfo As New ProcessStartInfo("cmd.exe") '调用程序名        With startInfo            .Arguments = "/C " + cmd '调用命令 CMD            .RedirectStandardError = True            .RedirectStandardOutput = True            .UseShellExecute = False            .CreateNoWindow = CreateNoWindow        End With        Dim p As Process = Process.Start(startInfo)        Dim strOutput As String = p.StandardOutput.ReadToEnd()        Dim strError As String = p.StandardError.ReadToEnd()        p.WaitForExit()        If (strOutput.Length <> 0) Then            Return strOutput        ElseIf (strError.Length <> 0) Then            Return strError        End If        Return ""    End Function
