SetForeGroundWindow（）和SetFocus（）问题与对话框内的子模式对话框 [英] SetForeGroundWindow() and SetFocus() Issues with Child Modeless Dialog Inside a Dialog

问题描述

Hello Everyone，

我正在做一些传统的MFC工作，我正在尝试将焦点放在对话框中的子无模式对话框上。作为一个简单的测试，我在OnInitDialog（）期间调用了SetForeGroundWindow（）和SetFocus（）。我的对话框无法获得焦点;但是，当我附加一个
断点并逐步执行代码时，SetForeGroundWindow（）将正确设置焦点并且焦点仍然存在。

我不知道为什么代码仅适用于断点，不能在没有断点的情况下工作。

有没有人对此有任何见解？

谢谢，

Matthew

解决方案

SetForegroundWindow功能

Hello Everyone,

I'm doing some legacy MFC work and I'm trying to set focus on a child modeless dialog inside a dialog. As a simple test, I've made calls to SetForeGroundWindow() and SetFocus() during OnInitDialog(). My dialog will not get focus; however, when I attach a breakpoint and step through the code, SetForeGroundWindow() will properly set the focus and the focus persists after.

I'm not sure why the code works only with a breakpoint and no longer works without a breakpoint.

Does anyone have any insight into this?

Thanks,

Matthew
