windows程序设计

[不爱吃酸的大力水手]

为什么windows程序这本书从第十章开始，程序可以编译，但显示出来的界面确什么都没有呢，这是什么情况啊，就只是显示一个空白的界面而已，希望学过这本书的人指教，我用的是vc++6.0

就是编译程序结果都是这样的，为啥？？？？？

windows程序设计 这书俺没有也没看过

[林石公]

wndclass.lpszMenuName = szAppName ; 这一句，如果从菜单资源里加载应当可以显示菜单吧 一般情况下VC里会有RC资源文件，可以在里边配置一些东西， 当然，你应当可以完全动态的创建菜单，但从你的代码里似乎没有看到动态创建菜单的代码

那要怎么搞啊，书里面也没说啊，可不可以帮我改下呀，老大

[不爱吃酸的大力水手]

就是《windows程序设计》嘛，帮个忙啊，解决下嘛

[林石公]

万一火了呢 no code u c a j8

为啥VC6的问题要到Delphi区来问？

[sololie]

因为俺没看过也不知道《windows程序》是啥书，不明觉厉
