》》》》SDK经典问题：如何把一个window做成一个文本编辑框(EDIT)？？？？

SDK可以直接生成edit控件啊，为什么要用Window做呢

我想把一个普通的window变成一个Edit
请问如何把光标放进去，如何让它接受键盘的消息（包括汉字输入），
当然，Edit中显示的内容还是得自己“画”

Edit控件功能太弱，另外我也想了解Edit是怎样有window变来的

我以前写过一个EDIT控件，用纯win32 API写的。
自己控制光标位置，自己控制字体。
比较麻烦。

}转自window程序设计

楼主可以去翻翻Charles Petzold的《Programming windows》，里面有
一些简单的例子，功能不是很强大，如果要再做强一点，估计得花点力气了

谢谢大家
我正在看《window程序设计》，上面的程序好象是“键盘”这章吧
关键是怎么把检测汉字输入法输入的汉字呢？
还有就是我加了给window加了scrollBar后不知道怎样控制

更简单的办法是，你使用mfc wizard可以直接生成该程序

现在剩下最后一个问题，怎么检测汉字输入的消息呢？
请大虾提供API和消息的用法

吐血. 换行时的半个汉字的问题解决了吗? CharfromPos(),等等,麻烦事一大堆.

一样（最烦MFC）支持！！！！！！！！！！！！！！！！
