c++ win32 列表框和 slider 创建 windows 应用程序

Question

我想在我的窗口中实现一个列表框和一个 slider 。我使用 devcpp，而不是 visual studio。

我一直在寻找一种方法来做到这一点，但除了像 msdn.microsoft.com 提供的理论内容之外，我一无所获。

我想要一个示例，一种实现列表框和 slider 的最小代码。这是更接近和最有用的链接，但它仍然使用 visual studio。谢谢。

Answer 1

我找到了我要找的东西，这似乎是整个互联网上制作列表框的唯一示例代码。为了运行它:下载并打开 devc++(我使用的)或任何其他类型的编译器，打开一个新的 Windows 应用程序项目(否则它将无法运行)，删除所有默认代码，粘贴此代码并运行它。

这就是您帮助他人学习代码的方式。
