Hi,
Is there any type of msgbox in vb.net that gives a message and disappears automatically after a certain time?
Or is there any method to hide the msgbox, without user''s clicking OK?

Thanks
Furqan

推荐答案

本身，不，因为该消息框在主UI线程上运行.它是一个对话框，从本质上来说，它是一个阻止操作.您将必须编写一个自定义对话框，该对话框可以在一段时间后自动关闭.当对话框显示时，启动一个计时器，该计时器设置为您要在此之后关闭对话框的持续时间，在计时器事件中，请关闭对话框.

By itself, no - because the messagebox runs on the primary UI thread. It''s a dialog so it is, by the very nature of it, a blocking operation. You are going to have to write a custom dialog that can close itself automatically after a period of time. When the dialog gets displayed, kick off a timer that''s set to the duration you want to close the dialog after and, in the timer event, close the dialog.

除非您想做一个模拟键盘输入的肮脏技巧(不，这不是我的建议；对不起，如果我给您这个想法，那将是很糟糕的:-)).

您可以创建一个自定义表单或窗口(您未标记UI；请参阅我对问题的评论)，而不是MessageBox.在这种情况下，您可以将其作为 模式 表单或窗口运行(多么不便！请始终标记您的UI库！)，使用计时器调用Hide或Close它.

我可能会警告您:这会违反预期的UI设计风格，并且可能会激怒用户.如果某件东西具有确定"和/或取消"按钮，则用户期望是决定何时关闭它的人.考虑使用类似ToolTip之类的东西，或使用行为类似于ToolTip的控件.

Not really unless you want to do a dirty trick like simulating keyboard input (no, this is not my advice; sorry if I gave you this idea — it would be pretty bad :-)).

You could create a custom form or window (you did not tag you UI; please see my comment to the question) instead MessageBox. In this case, you could run it as a modal form or window (how inconvenient! please, always tag your UI library!) use a timer to call Hide or Close it.

I could warn you: this would violate expected UI design style and possible irritate the user too much. Is something has OK and/or Cancel button, the user expect to be the one who decides when to close it. Consider using something like ToolTip instead, or some control which behaves like a ToolTip.

您可以为此创建自己的消息框表单.重载采用消息文本和超时值的构造函数.在Form Load上编写一些逻辑，该逻辑将显示一条消息，直到超时值，然后自动关闭.

You can create your own messagebox form for that. Overload a constructor which takes message text and timeout value. Write some logic on Form Load which will display a message up to timeout value and then after close automatically.
