 Posted: Sat Dec 20, 2008 10:39 am Post subject: [Vb.net] Question about a Timer. |
 |
|
Well, I am making a timer that counts Hours, Seconds and Minutes. I've done everything so far but I need to know this one thing:
The Stop timer button stops the counting but when you start it again, the timers are back to default value. How can I make so that the timers only get paused?
Thx!

I don't get exactly what the problem is here, how are you losing count? You can also try stopping a timer by simply setting the Enabled property to false.
You may find this easier to do with the DateTime and TimeSpan structures
Just find the difference by subtracting.

| Code: | Public Class Form1
Dim Secs As Integer
Dim Mins As Integer
Private Sub Seconds_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Seconds.Tick
Secs = Secs + 1
Label3.Text = "Seconds: " & Secs
If Int(Label1.Text / 60) = Label1.Text / 60 Then Label2.Text = Label2.Text + 1
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

How about storing the time when the user starts, then make a timer tick every sec:
yourtime = $time - oldtime
(to lazy to actually make it xD)
should work...

Dim secs, mins, hours As Integer
Private Sub Time_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Seconds.Tick
secs = secs + 1
Label3.Text = "Seconds: " & secs
If secs = 60 Then
mins += 1
secs = 0
Label3.Text = "Minutes: " & mins
If mins = 60 Then
hours += 1
mins = 0
Label1.Text = "Hous: " & hours
End If
End If
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Time.enabled = True
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Time.enabled = False
End Sub |
eliminates the need for multiple timers, and keeps time
i dont know exatly what the point fo you button3 is, if it just resets it then
| Code: | secs = 0
mins = 0
hours = 0 |
