如果我用 Visual Studio 编译它然后工作，但如果我用 Code :: Block 编译它并执行编译文件然后窗口不会出现但是出现一个命令提示符：
"Process Returned 0 (0x0) execution time 0,266s
Press any key to continue"
为什么？
答案 0 :(得分：2)
在Windows上，console application和windows application应用程序类型之间存在差异。
尝试在Code :: Block项目中为windows application指定一个应用程序类型。

该简单测试项目是否包含.rc资源文件？如果窗口类注册引用了资源（例如字符串），那么实际上并不存在于可执行文件中的任何位置，那么这可能会导致问题。
我猜你的窗口创建在某个地方默默地失败可能是由于编译的应用程序中没有可用的资源。它看起来不像代码对返回值进行彻底的错误检查，因此您可能需要通过调试器来查看它发生了什么。
检查资源文件是否与它一起使用。将其包含在Codeblocks中，以便实际编译并再次尝试运行该应用程序。
