I am currently making a timer for a school project. Im a little new to VB.net and having a few problems getting the timer to work.

When the countdown timer gets to 0 the "-" sign appears in the wrong place. As in i get 0:-1

I would also like the text in the timer to turn red when it enters negative numbers. (Maybe Flash, but i guess that is very complicated).

Anyway here is my current code:


Public Class Form1
Inherits System.Windows.Forms.Form
Dim TargetTime As System.DateTime
Dim willy As Integer

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Try
willy = TextBox1.Text
If Timer1.Enabled Then
Timer1.Stop()
Else
TargetTime = Now.AddMinutes(willy)
Timer1.Start()
End If
Catch ex As Exception
MsgBox("No Time Set")
End Try
End Sub

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Dim Diff As TimeSpan = TargetTime.Subtract(Now)
Label1.Text = Diff.Minutes & ":" & Diff.Seconds
End Sub

I'm assuming you are trying to get an output of -0:1...etc..etc...?

Try wrapping the difference in Math.abs() and then concatenating a '-' at the if the output is negative.

Try this:

Thanks alot wayne, that worked a treat.

Any idea on how to get the label text to turn red in negatives?

tried loads of different things but none seem to work

ok now im using the code that wayne posted, but the minus's arnt quite working properly. with waynes code it works for -0:01 to -0:59 but goes to --01:01. Any suggestions?
