跨线程调用错误码：3  eInvalidInput              =  3

直接发送Windows消息。

void SendCmdToAcad(ACHAR *cmd) 
 
  { 
 
  COPYDATASTRUCT cmdMsg; 
 
  cmdMsg.dwData = (DWORD)1; 
 
  cmdMsg.cbData = (DWORD)(_tcslen(cmd) + 1) * sizeof(ACHAR); 
 
  cmdMsg.lpData = cmd; 
 
  SendMessage(adsw_acadMainWnd(), WM_COPYDATA, NULL, (LPARAM)&cmdMsg); 
 
  }
