Answer 1

看不到WndProc
应该封装到ClientPushManager了去吧要详细代码注释，等LX的

Answer 2

re：WndProc
窗口过程回调函数，用来处理消息的

Answer 3

  // Initialize application
  rc = cpManager->createClientPushClasses(cpManager, (HANDLE)moduleHandle);
  if (rc < 0) {
  LOG.error("CP: Error in creating the push class. Exit...");   
  return rc;
  }
  LOG.info("CP: Client push class created");   
  LOG.info("CP: Init waiting PIM notification messages...");
  // Main message loop
  while (GetMessage(&msg, NULL, 0, 0))  
  {
  TranslateMessage(&msg);
  DispatchMessage(&msg);
  }
  } catch(...) {
  LOG.error("CP: Generic error in client Push: Error = 0x%x", GetLastError());
  }
