Flashing System Tray Icon

Question

Can anyone advise me on how to go about making a system tray icon that flashes? I've created a network monitoring app that sits in the background and when the network goes down I want the icon in the system tray to flash. Not sure how to do this.

Thanks.

Answer 1

Set the Icon Property of the NotifyIcon object. Use a timer to toggle it, for example:

 

Code Snippet

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick

Static Toggle As Boolean

Toggle = Not Toggle

If Toggle Then

NotifyIcon1.Icon = My.Resources.Normal

Else

NotifyIcon1.Icon = My.Resources.IconRed

End If

End Sub
