JavaScript - Clock On Webpage Using Server And System Time?
Jul 8, 2011I need to add a clock to a web page. The clock needs to be synchronized with a server but I really don't want to have it constantly check the server as the page will be open 24/7 on several PCs. Is there some way to get the time from the server and then use the systems clock to keep it updated and check the server every 15 minutes or so to keep it synced?
View 4 RepliesSynchronising Clock With System Clock?
Mar 12, 2009I'm a totally newb to VB and I want to do this. I want to do display system clock into a textbox. The trick is that I want it to be synchronized with the Windows XP clock. I want to have something like +/- 100 ms accuracy.
Each 'second' change will trigger an output pin to ground into the parallel port. This is very important that the 'second' change in the same time the Windows XP second change. Do not care about the parallel output thing, I'm nearly there. My main concern is the synchronisation with Windows clock.
In my code, I've added a counter that increment +1 at each 'second' change. So, when the 'n' value will reach a determined value, it will trigger another event.

I searched on the net and I found a thing about NIST time server.. Maybe this could be an otpion, but I have even no idea about how using it... I'm a total newb, but I'm ready to learn. So, please use simple language, no hard to understand acronym etc.

View 1 RepliesClock - UTC - Give The Users Current Time Zone/local Time
Jul 22, 2011So I currently have the following:
2 timers
2 labels
1st label is "Clock" this pulls the time from the users current time zone/local time
2nd label is "UTCClock" Which would be UTC time
Now I have this for the first label: clock.Text = Format(TimeOfDay, "hh:mm:ss tt")
Which would give the users current time zone/local time. As for the UTC.. how would I add in for the UTC time from where the user is located at? I did some searches.. but couldnt find what I was looking for.. IM pretty sure its not as easy as getting the users current time zone/local time.. So im assuming that Theres a "bit more" code into getting UTC time..

View 7 RepliesGetting The Time From An Atomic Clock?
May 28, 2010I'd like to write a small app to get the time from an "atomic" clock -- I believe the UTC time and then compare this against the system clock.
So far I've been able to get the system time details with the code below but just cannot figure out where to start on getting the atomic clock(s) time.
I did Google this for examples and have not found anything useful, I did find a list of atomic time servers @ the following URL and realise I have to connect to NIST Internet Time Service clock

View 3 RepliesSync With System Clock?
May 22, 2009I'm writing a logging program that should log some values each 10 seconds, but I want these 10 seconds to be in sync with system clock e.g 8:32:00, 8:32:10, 8:32:20 e.t.c. One way to achieve this would be to use a timer with quite small interval like 0.2 seconds and do logging if the right time has come, but maybe there is a better way?
View 2 RepliesAlarm Clock - Launching App @ Certain Time
Dec 4, 2010I would like to make an alarm clock application, however I am having some problems in the brainstorming phase.
My main problem is the fact that I dont know how to ensure the application will be able to calculate the time and thus set off the alarm. For example, when the application is closed, how will the alarm go off?
Ideally I would like to make this app a system startup item, so if the system is rebooted, the application will automatically relaunch - but again, I dont know how to do that.
If the system is sleeping, how can I wake it up? These kind of problems.
Another dilema I have, is if this application is always running, how could I have it go to my taskbar hidden icon menu (the right section of the taskbar next to the time).

Mar 30, 2011I have a table which contains the start date and end date, in my db. What I currently do is simply display both the fields in a ListView control.

But the only difference is, I'm going to display a clock's image as background and the shading is based on the time.
View 25 Replies'global' Type Timer That Will Allow To Basically Run Clock Entire Time Someone Is On Site
Oct 21, 2009I'm in need of a "global" type timer that will allow me to basically run a clock the entire time someone is on my site, no matter what pages they go to. I've played around with the timer available for forms but I didn't see a way to make it continue to run after someone left that page.The effect I'm attempting to create is for a timer to start whenever someone hits my site, then every X minutes an event will trigger. This event should happen no matter where they are on the site. I've read a couple articles on timers but to be honest I'm fairly new to VB and I didn't know if I really needed to learn about 'threading' etc, to get a timer to work.

View 2 RepliesAvoid A Possible Hang By Limiting The Time A Method Is Allowed To Take?
Jul 6, 2011I am using an external DLL (pdfsharp) to open (then manipulate) lots of PDF files. I use: Dim inputDocument = Pdf.IO.PdfReader.Open(PDFPath, IO.PdfDocumentOpenMode.ReadOnly) Problem is - it seems to hang on certain, rare files. I don't seem to get any timeout - it just hangs for hours on this line. We read thousands of files with this code, always on tiny files, so I was thinking that a quick workaround might be to somehow timeout if the this method takes more than a second or two. But I don't see a simple way to do this. I am hoping to avoid spinning up a worker thread.
