.Net Coding Challenge #3

[Resistance]

Challenge: Stop Watch
End date: April 21st, 2011
Details: Create an application that starts a timer to increase the value of a stop watch in milliseconds, seconds, minutes and hours. Use this website to convert the time. Create a stop button, pause button and resume button as well.
Requirements: Must have a stop button, pause button, resume button and the stop watch must have milliseconds, seconds, minutes and hours.
Optional: You may create a list box for this stop watch and a button to record the times at the time you clicked the record button.

How to enter:
Enter by responding to this thread stating are going to attempt this challenge. Do not PM me.

How to submit:
Submit by using a spoiler tag to hide you submission. Include a screen shot, the source code in {code} tags, a download link to the project. (Optional but preferred)

Choosing a winner:
If you complete this.. then you are a winner. This is not a contest to see who 'coded the best'. This is a challenge to see if you can complete it. Visual is Optional, but it will make your program look nice to the SF community.

Disclaimer:
This is meant to be fun and constructive. By submitting your code for this challenge you agree not to get butt-hurt if somebody criticizes your work. Take the criticism, learn from it, and move on. Also, all comments made should be constructive. NO FLAMING ALLOWED. All flaming attempts will be reported.

To everyone: Good luck.

Submissions:

I did not begin working on this, but it seemed like it would be a very fun little application as well. So if you do end up coding this, then you'll be happy that you finished the program, and also, you'll be able to put it to good use on your computer as to how long our computer nerdy butt stays on the computer.

This looks like quite a boring challenge to be honest (no offence).
I can't see the application being very useful

If I can be bothered I'll give it a go tomorrow.

[Untouch]

It's not really even a challenge, it's simple lol.
It's like one of the first programs you make when you start vb.

Edit: unless you actually create a stopwatch gui and can see the hand move.

[Modestep]

I have coded something like this before, but not with milliseconds, i will update what i already got to meet your requirements.

[Resistance]

Chillax guys. I would have made it harder if I wanted to so

Sidenote: Fragma, go and prove me wrong.

Wouldn't be to difficult.. just have to dust off the 'ol math book and draw some lines.

@High Roller
What do we need this website for?

[Fragma]

I'll give this till the end of today before I start Challenge #4.

Here's my take at it:

Code:

Imports System.Math
Imports System.Drawing
Public Class Form1
    Dim x1, y1, x2, y2 As Integer       'used for the points to draw the second hand line
    Dim iSecond As Integer              'used to hold vaule to make the second hand line
    Const HandLenght = 60               'used to determine the length of the line
    Const xDist = 190                   'used to help position the line horizontally
    Const yDist = 235                   'used to help position the line vertically
    Dim Pen As New Pen(Color.Black, 2)  'pen that draws the line
    Dim stpWatch As New Stopwatch       'used to count the time
    Dim iFix As Integer = 0             'I used this to fix the line blinking everytime the form refreshed
    Private Sub btnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.Click
        stpWatch.Start()
    End Sub

    Private Sub tClock_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tClock.Tick
        'if the stopwatch isn't counting, don't update the clock
        If Not stpWatch.IsRunning Then Exit Sub
        'added this to only refresh every second.. it was a quick fix
        'as I didnt want to spend forever making it look pretty
        If iFix < iSecond Then Refresh()
        iFix = iSecond
        'sets our iSecond value to that of the stopwatch
        iSecond = stpWatch.Elapsed.Seconds
        'creates our points to draw the line
        x1 = Sin(iSecond * PI / 30 + PI) * HandLenght / 5
        y1 = Cos(iSecond * PI / 30) * HandLenght / 5
        x2 = Sin(iSecond * PI / 30) * HandLenght
        y2 = Cos(iSecond * PI / 30 + PI) * HandLenght
        'draws the line onto the form
        Me.CreateGraphics.DrawLine(Pen, x1 + xDist, y1 + yDist, x2 + xDist, y2 + yDist)
    End Sub
    Private Sub tTimer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tTimer.Tick
        'if the stopwatch isn't running then exit the sub
        If Not stpWatch.IsRunning Then Exit Sub
        'if it is, update the labels with info
        lblMilli.Text = stpWatch.Elapsed.Milliseconds
        lblSec.Text = stpWatch.Elapsed.Seconds
        lblMin.Text = stpWatch.Elapsed.Minutes
    End Sub

    Private Sub btnPause_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnPause.Click
        stpWatch.Stop()
    End Sub

    Private Sub btnStop_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStop.Click
        stpWatch.Reset()
    End Sub

End Class

GUI could be a lot better but I don't plan on using this other than for this so I didn't try to make it look to glamorous. I don't think it looks incredibly bad though. About as good as you would want a stopwatch to look I guess. Anyways.. enjoy.

Very nice KoBe. If I were you though, I would have implemented the buttons onto the actual Stop Watch. So it would be kind of an actual stop watch, only on the computer.

Anyway I think I'll start up challenge #4 seeing as though this one hasn't been very popular.

I didn't even think about that. I just grabbed the image off Google, but it wouldn't be hard to turn that little knob into a button. With the white background it would probably be easy to animate the button being clicked as well.
