关于COMCTL32.DLL（高手请进）

[whowho]

一部分控件是在COMCTL32.dll中，其中包括了每个控件的窗口过程及注册窗口类的代码，他们在DLL加载时被调用。
问问：能写个代码出来看看吗（WINDOWS SDK），模拟一下COMCTL32.dll的运行过程

[Zark]

不知是什么意思?

你既然知道了控件的窗口过程及注册窗口类,也知道了DLL,哪还有什么可讲的呢?

我是想模拟controls面版上控件（如BUTTON）在FROM上的创建过程，但移动到FROM上的这个控件是包含在一个DLL文件中的

[Zark]

你是想模似写个resource editor(资源编辑器),还是想写个Custom Control(用户自定义控件)?

[whowho]

(资源编辑器)

[Zark]

写个资源编辑器是个工程量很大的活,如果你是一个人,又没有资金支持,我劝你还是算了.
