stopwatch function with button

[Syed Hadi]

for this start and stop should there on a button. but i don't want start and stop text on the button. let the button text bi button1 only when we press the button the timer should start on a lable and when we again press the button the timer should stop and the lable time should bi zero. and when we again press it should start .
does anybody know ......the function what we have to use for it............. .

This is not a code writing service but if you post what you have along with a description of the problem and any error messages you get, we can help guide you to a solution.

If Button1.Text = "start" Then
            Button1.Text = "start"
            'startTime = DateTime.Now()
            Timer1.Start()
        ElseIf Button1.Text = "start" Then
            Button1.Text = "start"
            Timer1.Stop()
            'endtime = DateTime.Now()
            Timer1.Start()
        End If

by this when i m cliking the button one more time the timer is not stoping and not going to zero position

 If j = 0 Then
            Timer1.Enabled = True
            Timer1.Start()
            j = 1
        Else
            Timer1.Enabled = False
            Timer1.Stop()
            Label1.Text = "00:00:00"
            j = 0

i got it but not exact

[Syed Hadi]

but it not starting from zero its starting from where it stopped.
anybody know how the time start from zero with the same button.

Your logic fails: Look at line 2 and line 5 of the code block in post #3.

[Rabbit]

How you reset it will depend on which class you're using. There are many timer classes.

[Syed Hadi]

clases means you are talking aboout the time intervel period....... and also i want a message box to displayed in a particular time. like for every ten min message box should be displayed but it not comming on every then ten min as the min come to ten the message box is getting started may for every second mesage box is displaying am a freshier.... so plaease guide me ......

[zmbd]

Doesn't matter what you do until you fix the logic block as I've indicated.

[Rabbit]

@z, I believe their next code block fixes the original issue, albeit in an odd way.

@syed, I can't answer any of your questions until you answer my question in post #7 because a time interval period is not a class I've heard of nor can I find any such class for VB on the web. You must be using some other class that you need to tell us about.

Even if you answer that question, I have no idea what you said in the rest of your post. It is confusing and unclear.

see sir this is my all coding

LOL you guys are fighting a lost cause. Not much you can do without the correct info and you are right fix the logic try again post the next error. LOL

[Rabbit]

I can't make heads or tails of your code. You've commented out almost everything. I don't think your code will do anything at all much less the behaviour you described.

Syed Hadi:
If Rabbit had not replied, I would have deleted this as a homework question.

As your postings have progressed, the entire thread continues to give me the impression that this is a homework question and as such we should stop here until you can provide an example that actually works without basic logical errors or jumbled up half code.

Your initial code had a fundamental logic error.
The second code doesn't handle that logic error.
The third code does little if anything as Rabbit has pointed out.

Therefore, I respectfully ask that you take a few deep breaths, regroup, and then take a very hard close look at your project.

1) Write out in a single paragraph the major goals that you want the program to accomplish. This should be in "plain English." Not that you have to use English, just that you should not use any pseudo code, jargon, or other short cuts.

2) In a single paragraph, for each of the major goals, detail the steps. These also should be in "plain English."

3) You need to do a logic chart for your program. I prefer the NS style ( nassi shneiderman diagram Google Search ) however any programing flow-charting method will work. This should flow naturally from your work in (1) and (2)

4) Using the flowchart write the major blocks of code and then fill in with your support code as needed.

5) Compile and fix compiler-time errors.

6) Execute the program

7) Then come back here with any further issues.
