c++ - 鼠标单击手柄

我正在尝试处理屏幕( 客户端窗口外) 上的鼠标事件。 我使用纯 WIN32 API 。 我已经用SetWindowHookEx函数创建了单独的DLL,并将它的引用到 WIN32 应用程序。 但它只处理窗口事件,当鼠标在窗口或者窗口外时没有活动。

仅使用WH_MOUSE钩子钩子鼠标消息。

建议:

  • 确保钩子成功安装( SetWindowsHookEx返回非空值)
  • 确保传递给钩子过程的消息( 设置断点到这些点或者使用跟踪函数)
  • 你需要将目标窗口的HWND发送到每个进程或者发送广播消息
  • 对于 Windows Vista和更低特权的更高版本的进程,无法将消息发送到具有更高权限的进程。 你需要使用 ChangeWindowMessageFilter插件向过滤器添加必要的消息
  • 使用 PostMesssage 而不是 SendMessage,你不需要在这里阻塞呼叫
