SendMessage() 发出的消息 PreTranslateMessage() 不一定能接收到!

徘徊边缘 提交于 2020-02-04 05:39:07
今天在调试一个程序时,发现调用 SendMessage() 发送的消息,PreTranslateMessage() 接收不到;试了其它两个方法: (1) 换成 PostMessage() 来广播消息,则 PreTranslateMessage() 可以接收到。 (2) 仍然使用 SendMessage() ,将消息处理放在消息队列(BEGIN_MESSAGE_MAP)中处理时,也可以接收到。 分析了一下此问题的原因,记录如下: PreTranslateMessage 先于 WindowProc() 处理消息。 SendMessage() 发出的消息 PreTranslateMessage() 能否接收到,要区分环境。如果是对本线程的窗口 SendMessage(),则不经过任何消息循环,也不放入消息队列,直接调用WindowProc()。这样 GetMessage() 和PreTranslateMessage() 都捕获不到;如果 SendMessage() 是向其它线程或其它进程的窗口发消息,则消息进入消息队列,GetMessage() 和 PreTranslateMessage() 能捕获到这个消息。 PreTranslateMessage() 它是用来处理 PostMessage() 发出的,而不处理 SendMessage() 发出的消息;经过

关于<Java 中 RMI、JNDI、LDAP、JRMP、JMX、JMS那些事儿(上)>看后的一些总结-1

原文地址: https://www.anquanke.com/post/id/194384#h3-3 1.java rmi 关于rmi客户端和服务端通信的过程,java的方法都实现在rmi服务端,客户端实际上是通过访问rmi注册表拿到stub,然后再通过它调用服务端方法,那么调用方法时要传递参数,参数可以为一般类型,也可以为引用类型,那么如果为引用类型,就能够利用服务端已经有的gaget chain来打server,因为参数实际上是序列化传输的,那么数据到达服务端后必定会经过反序列化。 客户端: RMIClient.java package com.longofo.javarmi; import java.rmi.registry.LocateRegistry; import java.rmi.registry.Registry; public class RMIClient { /** * Java RMI恶意利用demo * * @param args * @throws Exception */ public static void main(String[] args) throws Exception { Registry registry = LocateRegistry.getRegistry("127.0.0.1", 9999); // 获取远程对象的引用

How can I send keys to inactive DirectX “ePSXe” window?

泄露秘密 提交于 2020-01-14 05:29:24
问题 I need to send a key to an inactive "ePSXe" window using C#. I got the handle of the window using Spy++, but when I used this code to send key "x", I got nothing. What should I do? I tried different values of Msg as 0x0100 , 0x0101 and 0x0102 , but nothing worked. I also tried SendMessage and the results were the same. [DllImport("user32.dll")] public static extern IntPtr PostMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam); private void Send_X(IntPtr p) { PostMessage(p, 0x0100,
