Start Windows Form-App hidden, only Notifyicon

Here is a VB.Net 2003 version.

Click on Project --> "Add Existing Item..." and then change the "File name:" to "*.Ico" so you can select an Icon for your Tray Icon.  Once an Icon has been added to your project, select and then in the Properties for it, change the "Build Action" to "Embedded Resource".

You need to change "face04.ico" to the name of the icon you added to your project.

Obviously all this app does is have an "Exit" option.  You can either add more menus or trap the left click event on the NotifyIcon to show a form...

Module Module1

    Public Sub Main()
        Application.Run(New MyAppContext)
    End Sub

    Private Class MyAppContext
        Inherits ApplicationContext

        Private ni As New NotifyIcon
        Private cm As New ContextMenu
        Private mi As New MenuItem("Exit")

        Public Sub New()
            cm.MenuItems.Add(mi)
            ni.Icon = New Icon(Me.GetType, "face04.ico")
            ni.ContextMenu = cm
            ni.Visible = True
            AddHandler mi.Click, AddressOf Me.mi_Click
        End Sub

        Private Sub mi_Click(ByVal sender As Object, ByVal e As System.EventArgs)
            ni.Visible = False
            Application.ExitThread()
        End Sub

    End Class

End Module

Hi Idle_Mind

I think that this is for only Tray-Icon, without any form. But I'm searching a way to load a Form, but not showing it. So when I click on it, it should set the form.visible to true and bring it it front...

I can do that all, but not load the form without showing it, cause after form_load it is showing itself always...

Ah Thanks, I did exactly that, but I took 100 instead of 1... :-)

Yeah...that's inconsistent eh?

Design-Time = 0 --> 100
Run-Time = 0 --> 1
