This is my 'help' thread I'll post here when I need help. >_>
I use VBS2008, Windows XP SP2.(Just to get that out of the way.)
Well my overall project is to make a Mushmom Timer, so I can use what I've learned so far. But I want to have the users current system time on the form as well. And I use:
| Code: | | lblSysTime.text = TimeString |
in the form_load and it just displays the current time but doesn't keep counting.>_> I've used it before and I even went back to that chapter in my book and redid it. But it still does the same thing.
So yeah, can someone help me!? D:
Also, I was trying to think of a way to change the timer time to count down like minutes but I'm not sure how. I was thinking of displaying it in a certain format. But yeah>_> Any help would be appreciated. SO YOU BETTER HELP! >:O

Use a timer on 100 interval and keep updating the time ( every second ).
As for counting down, you could also use a timer, then if it's 00:00 then stop the timer.

Awesome I got it to subtract 1.6666666666666667 from 4500 and used Int to round it up. Although I can't seem to think of a way to make it look like time. I tried putting this in with the Timer1_tick:
| Code: | If eventTimer - 60 then
eventTimer = eventTimer - 160
End If |
Of course those aren't the right numbers but you get the idea. So that it
makes it look like it counts down. But that didn't work lol.
But what I meant by the time thing is, I want it to show the users system time. Like, when | Code: | | labelx.text = TimeString |
it shows the time for that instance and doesn't update. Used to it would update. >_>

Lol I don't know how to use anything from MSDN.
A little help would be nice. :O

I made a quick example of count down in seconds (attached)

:O I know how to do the count down, it's just making it look like it's 45minutes.(45:00 and going down 60 that's the hard part.>_>) I've attached my version of the count down, it should take 45minutes to get to 0 but starts at 4500 so it looks similar to a clock.
Lol>_>, well I don't see why my TimeString doesn't work. It used to before. =/

| Code: | Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Timer1.Enabled = True
End Sub
Private Sub timer1_tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If Label1.Text <> 0 Then
Label1.Text = Label1.Text - 1
End If
End Sub |
how hard can it be?

Omgosh>___>
Ok look, I got that. But how is -1 every interval going to to do anything?
1 minute = 60 seconds riiigghhttt?
45 minutes = 2,700 seconds
Ok so I can't put 4500 and subtract 1 every time or else I'd end up with 75minutes!
So that's why I subtract 1.67 at every interval
because I can't make the next digit decrease after the other one has only gone down 6 like an actual clock. I tried something similar to that but it didn't work. I tested it and it's right on the dot(45mins). But I want something that counts down 45:00 like a stopwatch! Gosh.>_>
Although as I was typing that I got an idea a different timer for a different label, it turned out decent but I need to mess with it some more.

Intervals are done as milliseconds in VB.
1 second = 1000 milliseconds
1 minute = 60 seconds = 60,000 milliseconds
You should get the point on that.

Oh, my, god.
If we're counting down as a clock would. (New years)
Freaking it would go 200, 159, 100, 059. Right?
And - 1 every interval is like?
200 199 100 099 not 59...
I know that 1 second = 100 milliseconds and so on.
I've almost made my count down thing, but it uses different timers
and different labels. But I just need to adjust it a bit. Gosh>_>
Thanks for the help though.

I see what you're trying to do.
I would do it this way:
| Code: |
Private iHours as Integer
Private iMinutes as Integer
Private iSeconds as Integer
Public Sub Countdown()
iSeconds = iSeconds - 1
If iSeconds < 0 Then
iSeconds = 59
iMinutes = iMinutes - 1
If iMinutes < 0 Then
iMinutes = 59
iHours = iHours - 1
If iHours < 0 Then
Call Countdown_Done
End If
End If
End If
Call Show_Countdown
End Sub
Public Sub Show_Countdown()
Dim strTime as String
Dim strTemp as String
strTemp = iHours
If strTemp.Length = 1 Then
strTemp = "0" & strTemp
End If
strTime = strTemp
strTemp = iMinutes
If strTemp.Length = 1 Then
strTemp = "0" & strTemp
End If
strTime = strTime & ":" & strTemp
strTemp = iSeconds
If strTemp.Length = 1 Then
strTemp = "0" & strTemp
End If
strTime = strTime & ":" & strTemp
Form1.lblTimeRemaining.Text = strTime
End Sub
|
Set the timer's delay to 1000 so it fires once a second, and put Call Countdown() in it's event.
EDIT: Added some length checking to Show_Countdown to make sure it looks like a clock.
That should give you the 'clock' look. |

._.
I woulda figured that he just wanted to show like MM:SS
Here's C# (sorry, I don't know the modulo command in VB)
[code]
void Timer_Tick(object sender, TimerEventArgs e)
{
string sLblText = String.Empty;
int iMins = 0, iSeconds = 0;
Timer timer = (Timer)sender;
iSeconds = timer.Time / 1000; //I forget what the property of the timer is, to access the time, but whatever
iMins = iSeconds / 60;
iSeconds = iSeconds % 60; //modulo, the remainder
sLblText = iMins.ToString() + ":" + iSeconds.ToString();
MyLabel.Text = sLblText;
}

That's pretty much what I done but a little differently.
Why is call Countdown_Done there?
I don't know why the hell I didn't think of concatenation's when I was doing it but, wouldn't I need do:
| Code: | If strTemp.Length = 1 Then
strTemp = "0" & strTemp
End If |
for 1-9 and not just 1. All n' all thanks for the code, I'm gonna try it out and tweak it a little.
@Samuri25404
Heh yours is a little different
But I don't understand how yours works though. My minutes = my seconds \ 60? it started to seem to make sense then it kinda went away haha. I'll examine it more closely later. >_>
