Timer object anyone?

umm how do I work with it?
I'm declaring a new Timer object and adding a handle to its Elapsed event. Seems like my app hangs for some reason. Is there any dumb things that I can be doing wrnog?
I'm doing soemthing like this:

Dim t as new timer(2000)

....
t.start
addhandler t.elapsed, addressof blah


this is the whole thing in case you are interested to know. It's supposed to show the button two seconds after the mouse is hovered on the picturebox

VB Code:

Private t As New Timer(2000)
    Private Sub PictureBox1_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles PictureBox1.MouseEnter
        t.Start()
    End Sub
 
    Private Sub PictureBox1_MouseLeave(ByVal sender As Object, ByVal e As System.EventArgs) Handles PictureBox1.MouseLeave
        t.Stop()
        Button1.Visible = False
    End Sub
 
    Private Sub MouseHover2Seconds(ByVal sender As Object, ByVal e As ElapsedEventArgs)
        Button1.Visible = True
    End Sub
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        AddHandler t.Elapsed, AddressOf MouseHover2Seconds
    End Sub

very ingenious, right, hehe.

Does the code currently work and you're only having the problem with it going slow or does it not work at all?

noo aint workin. app hangs and hangs then stops repainting :) hehe I'm acting like a compelete newbee now:D

Why not just use the MouseHover event of the picturebox? Also I thought it was the Tick event you use.

VB Code:

Private Sub PictureBox1_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles PictureBox1.MouseHover
        Button1.Visible = True
    End Sub
 
    Private Sub PictureBox1_MouseLeave(ByVal sender As Object, ByVal e As System.EventArgs) Handles PictureBox1.MouseLeave
        'although unless the button is in the picturebox they wont eb able to click it
        'since it will disappear when they leave the picturebox to click it
        Button1.Visible = False
    End Sub

umm well! I wanted the button to appear AFTER a delay. Kinda like in IE when you hover over a picture, after a lil while it will show the save/print/bleh buttons :) I havent used timers so I'm gussing I'm doing something really wrong :eek:

Well that is what the MouseHover event does, but if you want more control over the time it takes or really want to use the Timer then:

VB Code:

Private WithEvents _Timer As New Timer
 
    Private Sub PictureBox1_MouseLeave(ByVal sender As Object, ByVal e As System.EventArgs) Handles PictureBox1.MouseLeave
        'although unless the button is in the picturebox they wont eb able to click it
        'since it will disappear when they leave the picturebox to click it
        Button1.Visible = False
        _Timer.Enabled = False
    End Sub
 
    Private Sub PictureBox1_MouseEnter(ByVal sender As Object, ByVal e As System.EventArgs) Handles PictureBox1.MouseEnter
        _Timer.Interval = 2000
        _Timer.Enabled = True
    End Sub
 
    Private Sub _Timer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles _Timer.Tick
        Button1.Visible = True
    End Sub

There is more than one Timer object so check which one you are using. I am using the one from the Windows.Forms namespace not the Threading namespace one.
