Hi Yurich. Thanks for the quick answer, but I still have some problems..
Your code:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs)
Dim start_time As DateTime = DateTime.Now
mins.Text = CType((DateTime.Now - start_time), TimeSpan).ToString();
End Sub
There is an error for (1) the semi-colon, and (2) the minus (-) sign for the two dates.
What I am trying to do is to use the system time to count 1 second, and on every second I want it to do something.
In my case, I want to decrement a counter.
no-no-no, first of all, move out start_time out of the tick event - it should be intitialized in some other place, where you start your stopwatch for example...
1) - remove ; sorry, my C# experience gets in the way ;)
2) stgange, - defined for two dates in c#... then it won't work for you...
if you want to decrement a counter, just put this one in your tick event:
Dim counter as Integer = 1000;
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs)
counter -= 1 ' decrement by one, you can change it of course
End Sub
and if you need it each second, change you interval for your timer to 1000 (1000 mils = 1 sec)
regs,
yurich

drop a timer on your application, add a variable "starttime", set it to DateTime.Now, you can leave the interval to 100 (100 milliseconds), and in the tick event of the timer add the following (label1 will show the time):
' that's in your page load if you want to start it right away on in the button event to start stop watch
Dim start_time as DateTime = DateTime.Now()
...
' that's in the tick event of your timer
Label1.Text = CType( ( DateTime.Now - start_time ), TimeSpan ).ToString();
Regs,
Yurich
