My system needs to capture the daily clock -in and clock out time of each worker. Each worker is only allowed to clock-in and out once a day. Im using visual studio 2008 currently and my database is using microsoft access. Below is that i used for my login.
[Code]...
So 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..
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()

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).

View 6 RepliesI 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 RepliesI am currently creating a clock like the "24" clock, i have made the numbers using the drawing tools within Visual Basic, i was just wondering how i can link the current time to corrospond with the shapes i have drawn?
View 3 RepliesIn my program's Form_Load I randomly generate a time value. Once I generate the time value, I put it in a DateTime variable. I need it to work like a clock. I know I can do this with a timer with an interval of 60000, or using TimeGetTime and updating a variable.Is it possible to do this with a thread?
View 3 RepliesI 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 instead of that approach, I'm thinking about displaying a 'clock' image and shading those areas with some color. This is similar to a Pie Chart. 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 RepliesI'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 RepliesI have noticed in a windows-based VB application I am working on when the "Automatically adjust clock for daylight saving changes" is de-selected, the time in the application is off by one hour. Is there anyway to make the application not sensitive to that and just display the date value that is retrieved from the database?

View 19 RepliesI'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 7 RepliesI need to capture what keys the user presses and put it in a textbox. However, I need to capture multiple combination. For instance, if the user presses (and briefly holds) SHIFT and 1 (number one) the text box should say "SHIFT + 1." I also want "real time" capturing, meaning as the user presses the keys the value changes.

View 12 RepliesSo I am hacking together an app which listens to traffic using SharpPcap library, it reconstructs the packets from sessions using the code from TpcRcon.
Listening and reconstructing part work on their own . What I want is on each packet arrival main window gets an event so it can display the packet , and when session is reconstructed display a complete packet (I am interested in HTTP ones) . -That is where it breaks with weird symptoms: for example right now it does not stop on invoking stop listening method - the sharppcap library function hangs there forever waiting on this line of code : m_pcapThreadEvent.WaitOne();//wait for the 'stopped' signal from thread
I also had it not working and crashing in sharppcap function because I had omitted one parameter in form delegate- which makes no sense, because form delegate does not deal with packet capture at all and only reacts on "New Packet" event from my "Listener" class (which is only there to notify main form)
My app starts as module main instancing class "Listener". MainForm has it
registered as friend with event and handles even "New Packet"
Main Form:
Private Sub uiListenStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btListenStart.Click
aLogger.AddMessage("Started Listening")
