button无法响应点击事件
我把一个button用setparent（）函数把父窗口设置成一个listctrl了。目的是想实现点击listctrl的时候把button 移动到被点击的单元格上（如果不设置成listctrl的子窗体，计算位置太麻烦），这个现在可以实现。但是点击button的时候在对话框的窗口过程里无法响应单击消息。
我用MFC实现上面的功能的时候，把listctrl关联一个类，然后在这个类里做消息映射是可以响应的。但是现在是用win API 开发，所以不知道如何才能做到？求各位大侠帮忙。

SDK，就需要实现MFC帮你实现的消息循环等

但是点击button的时候在对话框的窗口过程里无法响应单击消息。
把button 的父窗口设置为listctrl，当然就要在listctrl里响应button 的单击事件
[解决办法]
控件的消息响应函数根据控件种类不同和消息的不同，只会在控件对象本身或你父窗口中有消息响应。
你为了处理在单元格中显示编辑框和按钮的问题，便于计算就把父窗口设为listctrl，所以对话框就与编辑框和按钮没有直接关系了。
你要考虑你的设计意图去构建你的程序逻辑，
如果你的编辑框和按钮就是为了listctrl在单元格用的，那就设按钮父窗口为listctrl，并在listctrl对应类的对象消息处理函数中，把按钮的单击消息再传递给listctrl的父窗口(即对话框)；
如果你的编辑框和按钮是对话框上相关功能，只是为了计算显示位置时方便，建议不要改变对话框与按钮的父子窗口关系，而通过参数传递的方式把单元格的CRect传出来，用于显示编辑框和按钮。

请看代码，我测试过的。你需要修改成符合你自己的。

[解决办法]
我确实用了 SetWindowLog 替换 ListCtrl的窗口过程了，但是这个窗口过程具体怎么写我不清楚啊。
我是这样写的 如果是button点击就执行一个操作 如果是其他消息我就直接 调用对话框的窗口过程。
错！要调用原窗口过程。
