我的解决方案:

my solution:

inline static int CALLBACK BrowseCallbackProc(HWND hwnd,UINT uMsg, LPARAM lParam, LPARAM lpData)
{
  // If the BFFM_INITIALIZED message is received
  // set the path to the start path.
  switch (uMsg)
  {
    case BFFM_INITIALIZED:
    {
      if (NULL != lpData)
      {
        SendMessage(hwnd, BFFM_SETSELECTION, TRUE, lpData);
      }
    }
  }
  return 0; // The function should always return 0.
}

/*  BrowseForFolder                                                   */
/*--------------------------------------------------------------------*/
