I have a stopwatch that counts down to zero from a random time set when the app loads. Now what I want to do is when that timer runs out and someone clicks reset it again is random rather than the same time as before. My code is

I am using this line of code on form load event it is working very fine but i have to problems

What should i do please please help me code is as follows

I designing a stopwatch type OO program and am stuck on trying to figure out the split time function of a stop watch. I want to list the split times in a list box as the user presses the split button and also display the final split time when the user presses the stop button. I feel I'm real close but just can't get over the hump, especially trying to code in OOP. The rest of my program works fine (start, stop, elapsed time). I am programming in VB 2005 and will display my relative code from both the class and form areas.

I have an application that has several stopwatches. I would like to be able to 'sync' a stopwatch with another at any given time. I tried setting the Elapsed time of one stopwatch to that of another stopwatch but I get that that property is 'read only'.
View 2 RepliesETA: Using Environment.TickCount does not present the same problem. ETA2: I should add that I don't actually use the Forms.Timer in my app - as this would negate the use of a high frequency timer. I've used it here to simplify the code. ETA3: I've published a workaround as an answer below. I'm having problems with the StopWatch class that I'm observing on a laptop with XP but not a different laptop with Win7. Here's the test code:

I can pause the the stopwatch and resume but I dont seem to be able to edit the stopwatchs time. So lets say my time says 00:00:02 , i now want to pause the program which I can, but also change the stopwatch time to 00:00:10 and resume counting.
I'm having trouble with a Stopwatch one one of the user's machines. I'm using the Stopwatch class to track time elapsed on one of my applications, and it seems to work fine on everyone else's machine, but on one machine it goes really slow. It's probably 1/3 or 1/4 of the actual time elapsed.
Here's the

I'm currently trying to code a program which basically uses the stopwatch function to time the length of the users break. Basically when I work at home I want to allow my self 4% of my shift length in personal breaks.
So far I have

Dim ts As TimeSpan = elpsTmr.Elapsed

As Object, ByVal e As System.EventArgs) Handles txtshiftlength.TextChanged

The only fields I don't have working are hard ones. I'm trying to figure out how to subtract the length of the last break used from the minutes allowed to take and display it in a text box to display how many minutes you have left to take. And also to work out how many minutes have been used since the program has been opened or reset.
I've read numerous posts and threads about random number generation, but I havent' run across this.If I generate a bunch of random numbers, the results are radically different if I create a new Random generator for each number than if I use on Random generator for all the numbers. The results are much more consistent and evenly distributed if I use the same Random generator.I would have thought the opposite,because creating a new Random generator each time should reduce the number of random repetitions, if a different time slice is used to create the random number.[code]......

The thing is i need the program to click on a button on a website then open a new tab with the page it just clicked on, fill in email and click submit, then fill in the info that is above before pausing.

One the click of a button the stopwatch starts, then on the click of a second button the stopwatch stops then states either in a msgbox the time taken between the two button clicks.

I want to generate random numbers at regular time intervals. I am putting the random generation in a loop which works when a button is clicked. But since the Timer itself is a control, I don't know how to do it. I tried putting the timer in a module so I can access it inside the form.
But the following error occurs:
"Error 1 Handles clause requires a WithEvents variable defined in the containing type or one of its base types".
When I doubleclick the timer icon the code appears as follows.
Public Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
End Sub
