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?
View 2 RepliesIf i have a computer that runs so fast such that it could make over 9e18 ticks per hour, when stopwatch.elapsedticks reached its maximum, does it resets itself or stays at Long.MaxValue?
View 6 RepliesSo a timer's maximum interval is 1 which is a thousand ticks a second. A Stopwatch's frequency is 2238906 ticks a second on my pc...
I am wondering if there is a reliable way to trigger an event for each tick of the stopwatch without missing any ticks...
If I can somehow get a Tick event for the stopwatch, I believe I can increase the resolution of my input recorder....

View 2 RepliesIn Visual Studio 2008 I am using :Private Declare Function BlockInput Lib "user32" (ByVal fBlock As Long) As Long To stop input from occuring during a search-replace operation.
BlockInput(True) ' do not allow input during search and destroy
Dim cursorIcon As Cursor
cursorIcon = Cursor
Cursor.Current = Cursors.WaitCursor
Then setting it to false at the end of the operation. It did not work, so I thought maybe it was because I was calling it from a child window, so I created a function in the mainwindow, and ran it like this:
FrmMain.BlockFrmMainInput()With these functions is the Main window:

It did not solve the problem. I thought maybe it was because I was running under the debugger, so I tried compiling and running it debugger-free, but that did not do any better. I am still getting input when I double-click the mouse on either form.
Is there a way to add x seconds to a stopwatch once a button is pressed? the stopwatch is currently running by the way.

View 7 RepliesI 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 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.

View 3 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.

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 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

-Timers, but the timer lags too much.
-Stopwatch Class, still lags (little but still).
I need ms accuracy, my prg will replace a hardware stopwatch used in competition.
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.

With a program neovjitet (stopwatch), which can transfer from tiemr1 to timer4 or to timer 2. I want the button to leave this example: 00 Hr 05 min 00 and that starts to count from the back and to tell me how much money this koh must be paid to
And time is:
0min to 24 to 20 eu
24 min to 36 to 30 eu
36 min to 48 to 40 eu
48 min to 60 to 50 eu
Automatically and when to add each 12 min + 10 eu ie when done 01hr: 22min automatically pay out 60 eu.
If at all possible, how can my app detect the number, physical location, and size/resolution of monitors in use so as to define the program's parameters? Secondly, I have created a stopwatch variable ("Count"). I can't seem to get it to function properly unless using full seconds. In the following code, I have tried to use a fraction of a second (like .5) and using "count.elapsed.milliseconds = 500" and the program doesn't act like the code is even there...
Code:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
