Synchronising Clock With System Clock?

Mar 12, 2009

I'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.

[Code]...

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.

Sync With System Clock?

May 22, 2009

I'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?

How To Call Function On End Of Min Of System Clock

Jan 20, 2012

I have a code written in VB.Net that will run on multiple systems. One of the function of that code is to check for files in some folder each minute.If we run code on different system at different times, it is possible that timer will execute the function to check the files at different times on each system. Is there any way, to make the timer running in each system in sync with each other so that it doesn't matter when the timer start on each system, they all will check for the file at the same time.

JavaScript - Clock On Webpage Using Server And System Time?

Jul 8, 2011

I 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?

Creating A Punch Clock?

Sep 10, 2009

What do you believe is the best way to have the program find the same row it created for a "Punch-In" for a single user. To clear this up what I have is a data table with the columns: Employee Num, Date, TimeIn, Timeout, Lunchout, Lunchin. And what I want it to do is when you first punch in, create a row for the specific user, then find that row later on and continue filling out what they do next. (make sense?) I don't have a ton of the sql + vb experience and I am having trouble figuring out a way to do this.

Getting The Time From An Atomic Clock?

May 28, 2010

I'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

Dim localDirect As Date = Date.Now
Dim utcDirect As Date = Date.UtcNow
Dim localFromUtc As Date = utcDirect.ToLocalTime()

Alarm Clock - Launching App @ Certain Time

Dec 4, 2010

I 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).
