如何强制AfxMessageBox中心在大型机上，而不是当前有焦点的任何子窗口 [英] How to force AfxMessageBox to center on mainframe and not whatever child window that currently has focus

问题描述

我正在开发一个MDI应用程序，主文档在MDI框架中最大化。我创建一个非模态对话框弹出窗口，以便在用户在主窗口中工作时向其显示辅助信息。然而，当用户移动弹出窗口时，它需要预期的焦点。当此窗口具有焦点并且在大型机中发生生成AfxMessageBox的事件时，会出现问题。我会期望AfxMessageBox弹出在大型机的中心。目前，它弹出以非模态对话框弹出窗口为中心，这是偶然的时候有焦点。

I'm developing an MDI application, the primary document is maximized in the MDI frame. I create a non-modal dialog pop-up to display secondary information to the user while they work in the main window. However, when the user moves the pop-up it takes focus which is expected. The problem occurs when this window has focus and an event which generates an AfxMessageBox occurs in the mainframe. I would expect the AfxMessageBox to pop-up centered on the mainframe. Currently, it pops up centered on the non-modal dialog pop-up window which, by chance, had focus at that time.

有一种方法强制AfxMessageBox总是弹出中心在大型机？或者至少强迫它弹出在它被调用的窗口的中心。例如，如果在我的非模态对话框中发生错误，我会希望AfxMessageBox出现在该对话框的中心，因为它是直观的，错误发生在那里。或者，如果我使用非模态对话框，并在大型机或文档中发生错误，那么我想AfxMessageBox出现在它的视图/框架的中心，尽管事实上，我目前使用子窗口。

Is there a way to force AfxMessageBox to always pop-up centered on the mainframe? Or at least force it to pop-up centered on the window in which it was called. For example, if in my non-modal dialog an error occurs, i would want the AfxMessageBox to appear centered on that dialog because it's intuitive that the error occurred there. Alternatively, if I'm working with the non-modal dialog and an error occurs in the mainframe or document then I would like the AfxMessageBox to appear centered on it's view/frame despite the fact that I'm currently working with the child window.

我希望很清楚。

推荐答案

c $ c> AfxMessageBox 但重写 DoMessageBox 的CWinApp子类。在你的覆盖中做任何你想使用 :: MessageBox（）显示一个消息框，甚至显示一个自定义对话框。这可以节省您在源代码文件中替换 AfxMessageBox 的调用。

Keep using AfxMessageBox but override DoMessageBox of your CWinApp subclass. In your override do whatever you want to display a message box to the user using ::MessageBox() or even displaying a custom dialog box. This saves you from replacing calls to AfxMessageBox across your source code files.
