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?

So 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....
On Visual Studio 2008 I am running into problems with strings longer than 30 characters, which become blank. My context is slightly unusual (perhaps) - but I dont see why it should not work.I am calling a VB2008 script from C++ using the COM interface [URL].. It works fine with integer and real arguments, and with strings up to 30 characters long.(see below - the example above is easily generalized to arguments as String, in which case the C++ code declares a BSTR object and uses L"xxxx" to set the string to "xxxx").
Surprisingly, I get a problem if the C++ string exceeds 30 characters in length - the string received by the VB routine becomes "" , ie, completely blank.I checked and this is not just a limitation of the debugger viewer - it really is "". However there is no problem with local strings exceeding 30 chars - the problem appears in passing of the argument, both byVal and byRef.

I'm trying to get a specific error message posted when a user tries to upload a file that exceeds the maxrequestlength of 10MB for my asp:fileupload object. However, adding the onError attribute to my fileupload object, the user does not get the error I want displayed; the page just crashes. Setting customerrors mode to on and setting up a redirect page doesn't work either; the page still crashes. How am I supposed to get the page to display a specific error without crashing?
View 1 RepliesI've drawing text to a rectangle, say for example "ABCDEFGHIJKLMNOPQRSTUVWXYZ123456789",That should be centered (which it is), but be on one line, not clipped like this:
"ABCDEFGHIJKLMNOPQR
STUVWXYZ123456789"
my String Format is:
With sfFormat
.Alignment = StringAlignment.Center
.LineAlignment = StringAlignment.Center
.Trimming = StringTrimming.Character
.FormatFlags = StringFormatFlags.NoClip
End With
It doesn't even have to trim it, like I have in my code, but it won't even stay on one line.
I had some trouble a while back with my progress bars exceeding their maximum sizes. I though I had fixed the problem but obviously I was wrong every time the maximum size is exeeded the application enteres debugging mode .... this is really frustrating as the progress bars are a major factor in the game...
What I have is one progress bar which is linked to a clock the clock which ticks up to 1:30 and the game then ends. I also have another progress bar showing the health of the shooter.
I have a series of collision codes set up which are linked to these progress bars, that add to them and take from them.
'Heath pick up collision code...
If (HPU.Top + HPU.Height >= Shooter.Top) And (HPU.Top <= Shooter.Top + Shooter.Height) And (HPU.Left + HPU.Width >= Shooter.Left) And (HPU.Left <= Shooter.Left + Shooter.Width) And HPU.Visible = True Then

I have tried re-routing the overload so that if it cannot add no more to the progress bars it adds nothing to them.
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.

View 9 RepliesI 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 10 RepliesI 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 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. 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:

View 4 RepliesI 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.

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.
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

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...
