消息框问题 [英] Message Box Issue

问题描述

大家好，我仍然遇到一个问题，即同时从同一表单向用户显示多个消息框

。这个问题

隐藏了表单背后的方框，因为表格大部分时间占用整个

桌面时最大化而且方框只有
$ b使用ALT时$ b可达。单击多个OK按钮后，

应用程序冻结并需要重新启动。


之前我已发布此消息并且一般响应为

" MessageBox.Show（）停止调用所有代码，直到用户

单击OK - 在这种情况下，会发生一些事情，允许

代码再次循环，同时显示OK消息框

在屏幕上点击OK然后显示第二条消息

来自同一表格的盒子。


亲眼看看：

这个小的示例应用程序显示了2个消息框，如果这个

是一个较大的程序，那么第二个框需要点击确定，然后单击确定首先是整个程序的后面并且只能通过ALT TAB或在任务栏中单击它来获得

。怎么可能这个

？！？

解决方案

jburkle，

我要做的第一件事是重构所有如果用the

自定义异常保护条款而不是exitSub'的

Hello all, I am still having an issue where multiple Message Boxes are
being displayed to the user from the same form at one time. This issue
hides the boxes behind the forms since the forms take up the whole
desktop most of the time when maximumized and also the boxes are only
reachable when ALT is used. Once the multiple OK buttons are clicked
the application freezes up and needs to be restarted.

I have posted this before and the general response is
"MessageBox.Show() stops all code from being called until the user
clicks OK" - while in this situation, something happens that allows the
code to be looped through again while the OK Message Box is displayed
on screen BEFORE the OK is clicked which then shows a second Message
Box from the same form.

See for yourselves:

This small example application has displayed 2 Message Boxes, if this
were a larger sized program then the second box which needs to be
clicked OK first would be behind the whole program and only reachable
through ALT TAB or clicking on it in the taskbar. How is this
possible?!?!

First thing I would do is refactor all the if thens to guard clauses with
custom exceptions instead of exitSub''s
