如何在使用 CreateWindow 创建的窗口中设置默认按钮，而不是在 Windows 中设置对话框资源？

问：

我正在开发一个 Windows 应用程序，我需要使用该函数创建一个自定义窗口。但是，我注意到当我使用对话框资源时，我可以设置默认按钮，但是当我使用 动态创建窗口时，我不确定如何做到这一点。CreateWindowCreateWindow

有没有办法在不依赖对话框资源的情况下在使用 CreateWindow 创建的窗口中设置默认按钮？如果是这样，实现这一目标的最佳方法是什么？我想确保默认按钮突出显示，并且可以在窗口处于焦点时通过“Enter”键激活。

我一直在网上进行广泛的研究，但我无法找到任何关于如何处理这种特定情况的明确信息。以下是我的代码摘录：main.cpp

我尝试使用 ，但我找不到使它按预期工作的方法。似乎我可能需要手动处理 和 事件，但我不确定如何进行此操作以确保功能正常。DM_SETDEFIDDM_SETDEFIDDM_GETDEFID

我正在寻找有关如何有效管理 和 事件或任何其他推荐技术的指导，这些技术将使我能够在 Windows 应用程序中为使用 CreateWindow 创建的自定义窗口设置默认按钮。DM_SETDEFIDDM_GETDEFID
