求救！通过RAPI从设备复制文件到PC，有知道的吗?
’工程引用了“OpenNETCF.Desktop.Communication.dll”
Imports OpenNETCF.Desktop.Communication

Public Class Form1

  Private Sub btnCopyFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCopyFile.Click

  Dim myrapi As New RAPI
  Dim strSource As String = "\My Documents\in.txt" 'PocketPc 这个文件通过ActiveSync能浏览到
  Dim strDestination As String = "E:\in.txt" 'Pc 本机文件

  Try

  ' 连接到设备。
  myrapi.Connect()
  'Do While Not myrapi.DevicePresent
  ' MessageBox.Show("Please connect your device to your PC using ActiveSync and " & _
  ' "before clicking the OK button.", "No Device Present")
  ' myrapi.Connect()
  'Loop

  '从设备复制到计算机
  myrapi.CopyFileFromDevice(strSource, strDestination, True)'这步报错：Could not open remote file

  '从计算机复制到设备
  'myrapi.CopyFileToDevice(strDestination, strSource)

  Catch ex As Exception
  MessageBox.Show(ex.Message.ToString)
  Application.Exit()
  End Try

  End Sub

End Class


有知道的高手指导下吗，不胜感激！
