"Not Responding" Message in Windows Form Application

[G_Zola]

When there is a statement in a windows form application which is executing in an infinite loop, the name of the form will show "Not Responding". How does .NET determine if the application is in an unstable state? I wonder if WMI is the right way to track the application? If so, what is the right way to start? If not, is there a way to determine the unstable state of an application? Welcome any advice

When your app is in an infinite loop, then usually no windows messages are processed and thus your app is not responding. So "Not responding" is just another word for "Not processing messages". You can make your app responsive either by putting the loop code in a separate thread or by calling Application.DoEvents() inside the loop. Regards, mav

I think a separate thread will be more accurate since you may want to make another loop or any ting else.
