厚着脸皮来发帖，两年来一个人自学有着说不出的苦逼，好比一人在大海里游荡，不分方向、、、唉

[sinat_33003903]

代码是电子书上敲下来的，《windows程序设计第五版》字还是繁体的，这书真的越看越不懂，只能通过敲代码来理解书，前面几章还好，后面的例子都有在前面没有介绍过的API，只能百度和MSDN，可能是我看书不特么的认真，有网友说书不用那么认真看，认真的的话这书要花多少时间呢，到后面做东西的时候会慢慢懂得。人生有限啊、、我发前两个贴都是自己太粗心，函数名学错了 都不懂
代码如下： 问题就是运行成功有进程，窗口就是不出来

这个地方跟书上不同

书上是这样的

按书上的话是错误的 如下


我用的是vs2012
