<p>I know I can programatically make the taskbar item for a particular window start flashing when something changes, but is there any way I can stop it from flashing either programatically after a certain period of time or at least is there a keyboard shortcur I can give to my users to somehow stop the flashing?</p>

It is hard for users to concentrate when a taskbar button is flashing, so you should assume that users will immediately stop what they are doing to make the flashing stop. Consequently, reserve taskbar flashing only for situations where immediate attention is required.</p>\n</blockquote>\n\n<p>Of course who knows who actually follows those guidelines ... or who even reads them. :)</p>\n'}, {'answer_id': 297178, 'author': 'Marcus Erickson', 'author_id': 38373, 'author_profile': 'https://Stackoverflow.com/users/38373', 'pm_score': 2, 'selected': False, 'text': '<p>Instead of flashing the tasbar you can consider using the NotifyIcon. This will let you put something on the system tray (something else many consider evil because of the proliferation of apps that do this). Then you can popup a ballon tip with any change that actually describes the change itself.</p>\n\n<p>To use:\n(1) Drag the NotifyIcon onto your form or create in your app NotifyIcon notify = new NotifyIcon();\n(2) Set the icon property to the required image\n(3)  Control whether it is visible on the system tray using the Visible property\n(4)  Call ShowBalloonText to show popup text (limited to 64 characters)</p>\n\n<p>Either way, you shoudl add an option to the program that allows the end user to turn this feature on/off based on their feelings about it all. I personally like the notify icon because the ballon text can say something like "Server went down"</p>\n'}]
