MessageBox loses focus in maximized MDI form

问题

I have an MDI application (written in .NET 2.0) which lets users open multiple child forms. The child forms are always maximized inside the MDI parent. When the MDI parent is maximized and I attempt to do a MessageBox.Show, the MessageBox doesn't show. If I do an alt-tab (or even just press alt) the MessageBox pops to the front.

Any ideas how to make that sucker show up to begin with?

This is only a problem when the MDI parent is maximized...

回答1:

Try using MessageBox.Show(Window owner, string message, string caption) Setting the MDI application as owner so the MB is shown in the front

Ah, you should also add some tags to your post.
