I have added a notify icon to my application. It works well. When the application starts, I see my icon in the system tray. Now, from the form, I can minimize. When I do it, I have added this code in the form resize event to not show the task in the task bar:

    Private Sub Form1_Resize(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Resize
        If (FormWindowState.Minimized = WindowState) Then
            ShowInTaskbar = False
        End If
    End Sub

But, doing this is closing my form for good as if I would have close it manually. I don't know what triggers the close event to be fired. Anyone would have any idea?
