你必须发送一个窗口消息窗口中的应用每5分钟一次。所以看看SendMessage功能 http://msdn.microsoft.com/en-us/library/windows/desktop/ms644950(v=vs.85).aspx

只是设置了一个定时器并使用System.Windows.Forms.SendKeys.Send方法！

Answer 5

另外，您可以的平台，USER32调用PostMessage的：

[return: MarshalAs(UnmanagedType.Bool)] 
[DllImport("user32.dll", SetLastError = true)] 
static extern bool PostMessage(HandleRef hWnd, uint Msg, IntPtr wParam, IntPtr lParam); 

这无疑是一个更好的方法，因为它允许您指定的hWnd，从而允许您将击键发送到AREN”窗口t本地呼叫者：

/// <summary> 
    /// Sends keystrokes to the specified window 
    /// </summary> 
    /// <param name="hWnd">Window's hWnd</param> 
    /// <param name="keys">String of keys to send</param> 
    /// <returns>Returns number of keystrokes sent, -1 if an error occurs</returns> 
    public int SendKeys(int hWnd, string keys) 
    { 
     if(hWnd <= 0 || keys.Length == 0) 
      return -1; 

     int ret = 0, i = 0; 

     System.Text.StringBuilder str = new System.Text.StringBuilder(keys.ToUpper()); 

     str.Replace(Convert.ToChar("`"), Convert.ToChar(0xC0)); 
     str.Replace(Convert.ToChar("~"), Convert.ToChar(0xC0)); 
     str.Replace(Convert.ToChar("-"), Convert.ToChar(0xBD)); 
     str.Replace(Convert.ToChar("="), Convert.ToChar(0xBB)); 
     str.Replace("{TAB}", Convert.ToChar(0x9).ToString()); 
     str.Replace("{ENTER}", Convert.ToChar(0xD).ToString()); 
     str.Replace("{ESC}", Convert.ToChar(0x1B).ToString()); 
     str.Replace("{F5}", Convert.ToChar(0x74).ToString()); 
     str.Replace("{F12}", Convert.ToChar(0x7B).ToString()); 
     str.Replace("{SHIFTD}", Convert.ToChar(0xC1).ToString()); 
     str.Replace("{SHIFTU}", Convert.ToChar(0xC2).ToString()); 

     for(int ix = 1; ix <= str.Length; ++ix) 
     { 
      char chr = str[i]; 

      if(Convert.ToInt32(chr) == 0xC1) 
      { 
       _PostMessage(hWnd, 0x100, 0x10, 0x002A0001); 
       _PostMessage(hWnd, 0x100, 0x10, 0x402A0001); 
       Thread.Sleep(1); 
      } 
      else if(Convert.ToInt32(chr) == 0xC2) 
      { 
       _PostMessage(hWnd, 0x101, 0x10, 0xC02A0001); 
       Thread.Sleep(1); 
      } 
      else 
      { 
       ret = _MapVirtualKey(Convert.ToInt32(chr), 0); 
       if(_PostMessage(hWnd, 0x100, Convert.ToInt32(chr), MakeLong(1, ret)) == 0) 
        return -1; 

        Thread.Sleep(1); 

       if(_PostMessage(hWnd, 0x101, Convert.ToInt32(chr), (MakeLong(1, ret) + 0xC0000000)) == 0) 
        return -1; 
      } 
      i++; 
     } 
     return i; 
    }
