有没有办法，使用的MessageBox做。您需要实现自己的形式，它看起来像一个MessageBox，但包含要看到有一个进度条和/或其他任何东西。

I want to set progress bar on my message box how to set ...progress bar property style have Marquee property..... Message box code is bellow.......

  MessageBox.Show("Data process please wait .", "Data progress ", MessageBoxIcon.Information);

There is no way to do that using MessageBox. You need to implement your own Form which would look like a MessageBox, but contain a progress bar and/or anything else which you want to see there.
