Win32组合框，打印所选要编辑文本框的名称

我正在为 win32 测试组合框。已经尝试了很多事情，但我不明白如何让它做我想让它做的事情。在组合框中进行选择时，我希望它打印到编辑框中。我相信这也许可以通过手柄来完成。

因此，如果我通过按钮 1 的强制转换将其添加到我的按钮 1 中，您如何让它打印到编辑字段？

我的代码如下。我留下了一些我尝试过的东西，但把它注释掉了。问题出在添加控件上，我正在考虑我的开关和情况。

我缺少将文本填充到编辑框的部分。

与其说我对编程不陌生，不如说我对这种类型的编程很陌生。我正在寻找一种简单的方法。提前感谢您的时间。

下面是更新的代码和我现在得到的内容。我遵循了 unicode 的准则。 我甚至与Visual Studio c++交了朋友(我认为)。
