拿来吧你，Compose尝鲜初体验！前言 Compose 正式版在七月份的尾巴如期而至，我也写了一份 Compose 版本的项目，Demo其实比较简单。地址：github.com/mCyp/Hoo。这已经是它的第三个版本：第一版：Kotlin + Jetpack 第二版：Flutter 第三版：Compose + Jetpack 还记得去年 Compose 推出的时候，我就在团队内部分享了一次 Compose，当时为了展示一个 Preview 的功能，差点卡到下不了台。其实写代码的时候速度还可以，但是投屏时属实有阅读详情

小第的VC才现在才刚刚入门哈！我想编制点简单的程序来提高自己但是就是连最简单的程序我都没法遍哈！我在这里想请各位高手帮下小第哈！我在这里感激不尽了哈！

我主要是想编个这样的程序：我在单文档里做了2个编辑框和一个控制按扭我只要在第一个

编辑框里输入数据20后按下确定按扭后，那么在第2个编辑框里就显示数据60；我在第一个编辑框里输

入30按下确定按扭后，那么在第2个编辑框里就显示90（其实我就是想用套用3X=？这个公式）。我就

是不知道怎么调用编辑框里的函数以及不知道怎么在这3个控件中添加代码，还有怎么把公式3X=？添

加进去我也不知道从那里下手。

请各位高手帮小第编下程序哈，小第由衷的感谢大家了！~~~~`谢谢！~~~~~

Unidbg逆向阿里系App签名：从环境补全到算法还原实战在移动安全与协议分析领域，理解应用层签名机制是核心挑战之一。签名算法作为保障通信安全与身份验证的关键技术，其原理通常涉及哈希、加密及密钥协商等基础密码学概念。在Android平台，核心签名逻辑常被加固并隐藏于Native层SO库中，以对抗动态调试与静态分析，这为安全研究和协议兼容带来了技术障碍。Unidbg作为一种基于模拟执行的逆向工程工具，通过模拟ARM指令集和系统调用，允许研究者在脱离真机环境的情况下，可控地执行和调试SO文件，为解决此类问题提供了创新思路。其技术价值在于实现了对加固代码的确定性分析与算阅读详情

你从这个地址下载MSDN，安装了就可以查：（2005.7月版）
http://soft.freestu.net/search.php?keywords=msdn&imageField.x=4&imageField.y=2
或者直接下载VS2005，上面那个站点也有，里面集成了最新版的中文MSDN。不过麻烦了点。

如果是MFC程序的话添加按钮消息响应函数,利用GetDlgItemText函数获得第一个框的数据,把获得的数据转换为整形再实现3X再转换为字符串行(用atoi和itoa函数),最后利用SetDlgItemText函数把结果设置在第二个框上,函数用法查MSDN,具体代码自己练习写下增加动手能力!

我也是新手，这个程序是用SDK的方式写的，
在一个主窗口中有一个编辑框控件，编辑框占用了整个窗口，所以看起来和普通的不太一样，但是因为都是涉及到了对编辑框控件的内容的存取，所以应该对楼主有一点用，不要看很长，其实重要的就几个函数调用。高手们不要见笑哈
（这些话是要放在上一贴开头的，可第一贴上的竟然不见了！又重新打了一次）
