I want to be able to put a continuing date and time text on an application.

I can use this fuction: Format(Now, "f"), which outputs: Monday, June 04, 2007 12:12PM ,but once the date and time is shown, it will stay the same forever...

I guess It would need to work with a timer or something, but can somebody please give me some help on this?

Thanks in advance!

Just throw it in a timer_tick event. Set its enabled property to true, and have it update every second.

yeh as Booze said.. add a timer to you application. set its event to whatever the code is to update your clock.. and enable it to update every 100 (thats in millisecs)

Yeh 100 milliseconds should be OK for you! Are you OK with the exact syntax? What you wrote looked good.

I have not done anything in VB.NET for a while but does an Timer object not need to be started explicitly rather than simply enabled? - Im sure it does, so enabling an instance in your application will be a little disappointing.

Very simple example to show what i think you want. Make a form, with a label, and two buttons, IF you click the first button starts the timer ( <timername>.start() ), second button ( <timername.stop> ). The rest you should be able to get from the code below.

 vb Syntax (Toggle Plain Text) 
Public Class Form1
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Timer1.Start()
    End Sub
 
    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Timer1.Stop()
 
    End Sub
 
    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        Label1.Text = DateTime.Now()
    End Sub
End Class
Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Timer1.Start()
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Timer1.Stop()

    End Sub

    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
        Label1.Text = DateTime.Now()
    End Sub
End Class

The attached is a all the files from my little test project, made in VS2005 SP1.

Yep but make sure you drag it from the toolbox first!
