I am writing a VB.NET application in VS2017, to run on Windows 10. I want the main (and only) Form to minimize down to a System Tray icon. That part I have working fine. The next part, display a Balloon Tip popup notification (e.g., "Application is still running"), is not working at all.
I have already checked/noted the following:
NotifyIconobject has an icon assigned to it in the designer grid as well as in the vb.net code-behind for the form, as does its associated
- The Group Policy on the the machine does not appear to forbid the use of Balloon Tips
- Balloon tips do not appear to be disabled in the registry
- The program works as expected in Windows 8.1 Pro and displays the BalloonTip, but does not in Windows 10 Enterprise N 2016 LTSB.
The machine is located in a domain that does have Group Policy administration going on, however the resultant policy set found on my machine does not seem to indicate that balloon tips have been disabled.
Copying-and-pasting exact code from StackOverflow does not work. The problem must then be in the system itself.
This is the code (which works on W8.1 but not W10):
Private Sub frmMain_Resize(sender As Object, e As EventArgs) Handles Me.Resize Try If Me.WindowState = FormWindowState.Minimized Then NotifyIcon1.Visible = True NotifyIcon1.Icon = SystemIcons.Application NotifyIcon1.BalloonTipIcon = ToolTipIcon.Info NotifyIcon1.BalloonTipTitle = "App Title" NotifyIcon1.BalloonTipText = "The App is still open!" NotifyIcon1.ShowBalloonTip(50000) ShowInTaskbar = False End If Catch ex As Exception ErrorHandler(ex) End Try End Sub
Where else can I look?
