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'.
ETA: 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 have a StopWatch running, I convert the milliseconds to the following format. 00:00:00 i.e HH:MM:SS which is a label.
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 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'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 using the timer to update the textbox that displays the time elapsed of the stopwatch every second.
Partial Public Class Private WithEvents breakTimer As New Timer Private breakSW As New Stopwatch
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 Public Class Form1 Dim elpsTmr As New Stopwatch Dim ts As TimeSpan = elpsTmr.Elapsed Private Sub txtshiftlength_TextChanged(ByVal sender _ As Object, ByVal e As System.EventArgs) Handles txtshiftlength.TextChanged [Code] .....
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 am using the stopwatch method to create a timer. I want to be able to have one button tell me the difference between the current time that the timer has and the last time i pressed the button.
Example: I start the timer, I click "Split time" after 3 seconds. I click "Split time" again 5 seconds later. The total elapsed time is 8 seconds but I want to get the difference of 5 and 3.
Also, how can I create a real-time timer that shows the running time as the form runs?
Using the datetime function to determine lapse time. (Subtracting one from another.) Then placing the answer into two text boxes one with the date and one with the time, later to be placed in a database as two seperate fields. Was thinking I could convert the date/time to a string if necessary then use simple stringmanipulation.... however fear it won't be good programming and will effect resources and end program speed.
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 am trying to split a long string based on an array of words. For Example:Words: trying, long, array Sentence: "I am trying to split a long string based on an array of words."Resulting string array:Multiple instances of the same word is likely, so having two instances of trying cause a split, or of array, will probably happen.
I have a VB.NET app in which I'd like to use the Stopwatch class. The stopwatch will get reset every time it enters a particular method, which may be in less than a second, or not for hours. Is there a limit to how long you can let a stopwatch run before something bad happens? i.e. an error, or performance degradation?
I would like to create a split container with a three way split. The first split is a vertical split. The second is creating a horizontal split within panel2 of the first split container. panel1 will hold a treeview control the other two panels will hold listview controls
I think this question has been asked already in a couple different ways and I've reviewed those posts and I've tried to do what was suggested but it doesn't seem to work for me. I've tried to place a second split container inside panel2 of the first split containter. This gave me what appeared to be a three way vertical split.
I have to create a cronometer or stopwatch. I'm not sure how to do this though. I have to have methods for starting it, stoping it, and reseting it. I'm thinking it might need to be a timer, but is this the only way? I have no idea how to work with timers or writing methods for them.
I am writing a very basic memory match card game, and am trying to get the program to flip over the selected cards, wait 2 seconds so the user can see the values, then flip back over. The code I have to do this is:
Private Sub Label_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.Click, Label2.Click, Label3.Click, Label4.Click, Label5.Click, Label6.Click, Label7.Click, Label8.Click, Label9.Click, Label10.Click, Label11.Click, Label12.Click, Label13.Click, Label14.Click, Label15.Click, Label16.Click Dim message As String = "Label Clicked was Index" + sender.TabIndex.ToString
I puzzle with (setting uptime-real time clock) calculation.ex. if I want my stopwatch countdown fromtart: 18.20.30 - stop: 18.50.50 = difference time is 00.30.20 that is easy butstart: 18.20.30- stop: 18.50.40 = difference time is 00.30.40
ok i know its not possible for a normal computer to exceed Long.MaxValue for Stopwatch.GetTimeStamp, but what is the scripted behavior of VB when Stopwatch.GetTimeStamp actually exceeds Long.MaxValue?
I use it as a timer(obviously) to get the lapsed time of an upload. Something that took 2 secs it said 12. [code] Everything looks right. and it seemed to be working. Just in no way did it take 8 or 12 secs to send
I have VS 2008 and wow is it different from the old VB I used about 10 yrs ago! What I am trying to learn is how to create an ap that has a window that displays elapsed time like a stopwatch. Then I would like to be able to click a button to pause that time and start another timer, and then have yet another button to reset all. I have the form designed using a RichTextBox but am not sure that is the best way to display the times.
So I'm getting closer and closer to making the timer work the way I want it to, with one small problem.
I found the following post about returning millisecond and nanosecond: How do you convert Stopwatch ticks to nanoseconds, milliseconds and seconds?
But what I'm trying to do is show only the 10ths of 100ths of a second when desired.
I have the following code:
Private Sub TotalTimer_Tick(sender As System.Object, e As System.EventArgs) Handles TotalTimer.Tick Dim elapsed As TimeSpan = Me.matchStopwatch.Elapsed
I am using Timer control as a stopwatch to populate couple of Label controls text field. I am listing the code below which is not updating the Label fields. I have removed the code related to buttons and other controls. Why is the Timer1_Tick not being invoked? The code is compiling clean and when I walked thru the debugger, my Start_Timer() and Stop_Timer() subroutines are working. However, nothing is happening in the Timer1_Tick() subroutine. I would like someone
