### Count down timer

So i've made this code in a project of mines, and i thought id share this piece of it.
Idk if there are any like this already, or better, but this was my method.

First, we declare 2 variables
Code: Select all
``Dim seconds, minutes As Integer``
Second, in form_load, we assign a value of your choice. My code counts from 7 Minutes, so ill go with 6:59
Code: Select all
``````seconds = 59
minutes = 6``````
Now in a timer, that will be triggered by your choice, add this code
Code: Select all
``````If seconds >= 10 Then
Label30.Text = seconds
Else
Label30.Text = "0" & seconds
End If

Label29.Text = "0" & minutes
seconds -= 1

If minutes = 6 And seconds = 0 Then
minutes -= 1
seconds = 59
End If
If minutes = 5 And seconds = 0 Then
minutes -= 1
seconds = 59
End If
If minutes = 4 And seconds = 0 Then
minutes -= 1
seconds = 59
End If
If minutes = 3 And seconds = 0 Then
minutes -= 1
seconds = 59
End If
If minutes = 2 And seconds = 0 Then
minutes -= 1
seconds = 59
End If
If minutes = 1 And seconds = 0 Then
minutes -= 1
seconds = 59
End If
If minutes = 0 And seconds = 59 Then
Label28.ForeColor = Color.Red
Label29.ForeColor = Color.Red
Label30.ForeColor = Color.Red
Label31.ForeColor = Color.Red
End If
If minutes = 0 And seconds = 0 Then
Timer3.Stop()
MsgBox("Time's Up!")
Button1.PerformClick()
End If``````
Of course, i did use labels to display the time. They turn red at the 1 minute mark.

Why don't you just store number of seconds and then mathematically using Floor and mod determine minutes/seconds?
Personally, I would store only number of seconds or milliseconds.

Good point. But it was more of a spur of the moment kind of thing, also not the best at math either, but once again pretty good point

When you have a variable with seconds, doing floor(sec / 60) and sec mod 60 would return number of minutes and number of seconds respectively. Not complicated at all, yet saves time by reducing number of if branchings.

Also, this code only works when minutes are less or equal to 6. Otherwise it counts down seconds to infinity. Instead of all those ifs, you could turn it to the following:
Code: Select all
``````if secs = 0 and mins > 0 then
mins--
secs=59
else
// time's up!
end if
``````
