I 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 12 RepliesI have a simple app that just shows the current time for specific locations around the world. I need to have it adjust for daylight savings time. I *THOUGHT* I'd already coded this but....
I thought I would use "Today.IsDaylightSavingTime()" and add 1 hour to the clocks. It isn't working?
If Today.IsDaylightSavingTime() Then
HawaiiOffset = HawaiiOffset + 1
PacificOffset = PacificOffset + 1
[Code]....
I have a form that has clocks for Hawaii, Pacific, Mountain, Central, Easter, GMT/UT, UK, Germany, Mumbai, Manila and China.I assigned a timer to tick the seconds and wrote the following code for the tick:[code]
View 8 RepliesIs there a way in VB.Net to determine if the timezone the current system has daylight savings time in effect? Of course I can get the offset from GMT using the "z"/"zz" formatting option, but that doesn't tell me if DST is in effect for the current timezone or if the current timezone is in standard time...or if DST/Standard time aren't even an issue in the timezone for the system.
View 4 RepliesI have a program which draws a U.S. map on the screen. This display looks great on my wide-screen (16:9) monitor, but it looks a little stretched horizontally on my wife's standard (4:3) monitor. Is there some way I can tell VB to automatically adjust the picture when a standard resolution is being used?
If not, am I correct in thinking that standard definition monitors are going the way of the dinosaur, much like is happening with TV's, and in the future we'll be seeing more and more wide-screen monitors.
I have a program that reads a file with Pacific Daylight Time, I want users to see the time and date in their local environment.
At present I have in Australia a time difference of 18 hours, so I have a list box with -24 to +24 and currently set at 18, my code is elementary as long as I have moved past day one of the month it suits me personally, but I want to distribute my app, so I need something better.
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..
In some text boxes I enter times like "08:00 16:00" then another textbox next to it will display 8 hours then a label at the bottom calculates the total overall hours. There are a total of 7 textboxes for times entered and like the example above and another 7 for the calculation of that days hours worked. My problem is when I enter "08:00 16:30" the total hours in that text box would be displayed "8.5 hours". I need to tweak this so it is displayed 8 1/2 hours. My second issue is that the label that displays the overall hours only calculates if I enter times like "08:00 16:00" if i entered "08:00 16:30" it would not calculate
Here is my code:
vb
Private Sub txtMondatTimeKeeping_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles txtMondayTimeKeeping.TextChanged, _
txtTuesdaysTimeKeeping.TextChanged, txtWednesdaysTimeKeeping.TextChanged, txtThursdaysTimeKeeping.TextChanged, txtFridayTimeKeeping.TextChanged, _
txtSaturdaysTimeKeeping.TextChanged, txtSundaysTimeKeeping.TextChanged
CalculateHours()
[Code] .....
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 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 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.
