NotifyIcon for a Service
-
Hi! I've written a windows service. This service can be in different states, for example running, paused, updating etc. To give the user a direct feedback of the services state, I want to display an icon on the windows system tray, which appears in different kind for each state...... The problem is, that the icon (System.Windows.Forms.NotifyIcon) is not displayed... but also no exception is thrown...
protected override void OnStart(string[] args) { //... NotifyIcon NI=new NotifyIcon(); NI.Icon=new Icon(@" ... "); //<- Path to an icon file NI.Text="My Service"; NI.Visible=true; //... }Can somebody tell me, why my NotifyIcon is not displayed? occcy -

NIvariable at the calss level. In the code exemple supplied by youNIwill be removed (by the garbage colector) at the end of theOnStartfunction scope. I hope you understand... By the way... visit http://nehe.gamedev.net[^] -

A sounder design would be the service "talking" to another program that displays the icon. Don't forget that services run even when there is no desktop, i.e., when no user is logged in. If you really must do it, there's the "allow service to interact with the desktop" checkbox on the service manager, but I strongly advise you not to use it, unless it's only test code... Yes, even I am blogging now!
