Question

当应用程序关闭时，NotifyIcon会停留在任务栏上，然后当我将鼠标移到它上面时，它会消失。

我在关机时试过这个，

Private Sub MyApplication_Shutdown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shutdown
    Form2.NotifyIcon1.Visible = False
    Form2.NotifyIcon1.Dispose()
End Sub

它仍然存在，对此有何建议？

感谢

Answer 2

对我来说，在设置Application.DoEvents()到Icon之后调用null并处置NotifyIcon时，它会有效。

Private Sub MyApplication_Shutdown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shutdown
    Form2.NotifyIcon1.Icon = Nothing;
    Form2.NotifyIcon1.Dispose()
    System.Windows.Forms.Application.DoEvents()
End Sub
