Using Timespan To Calculate Hours, Mins And Secs From Secs?
Apr 27, 2009
23430 seconds = 06:30:30 (hh:mm:ss)52230 seconds = 14:30:30 (hh:mm:ss)The problem occurs when my total seconds goes over 24 hrs. So for example,95430 seconds should equal 26:30:30 (hh:mm:ss) however comes out at 02:30:30.Here is the sample code, note I have tried using TotalHours, TotalMinutes TotalSeconds however this does not give the correct result. I potentially need to be able to calculate upto 1000 hours - e.g 3601839 should equal 1000:30:30 (hh:mm:ss)
Dim ts
As TimeSpan = TimeSpan.FromSeconds(95430)
Dim hours

I created a slideshow application for 4 monitors, with diferent folder for each screen images source.It has several transition effects and time schedule. It works superb when I am in VB Studio, developing, testing, etc.When I Build it, and play it work fine. But If I try the EXE file out VB environment, it work aprox 10 secs and "disaapears" from the screen, as if somebody press "QUIT"..I can't get any error or message from windows or VB.Again if I open the solution in VB it runs perfect.

I want to make something that can on button click navigate to a page, wait the time I specified and navigate to another page..
[CODE...]
This does not do what I thought it would do..I think that the problem is that when it sees System.Threading.Thread.Sleep(5000) everything stops for 5 secs .How can I make it go to google.com and then after 5 seconds, yahoo?

I am working on a timekeeping application in VB 2008 and need to show elapsed time in hours and minutes. I have no problem eliminating seconds but if the hours exceed 24 the time is displayed as days.hours:minutes and what I need is to show (for instance) 30 hours and 15 minutes as 30:15 not 1.6:15
Is there a better way then using code like:
strHours = (TimeSpan.Days * 24) + TimeSpan.Hours
strMinutes = TimeSpan.Minutes
strTotalTime = strHours & ":" & strMinutes

I would like to calculate the difference between hours and minutes from one textbox and the hours and minutes from textbox two. What would be the best way to do this? I think DateTime would be the object to use, but wondered if anyone has any examples or better ways?

I want to convert seconds such as 254565443 seconds to hours, minutes, and seconds and thought if I could remove the decimal and the numbers behind it and not change the number in front of the decimal then it would work.
dim seconds = 254565443
dim Hour
dim minute

I have a requirement that regardless of the start and dates that I need to loop through that timespan and calculate figures at the month level. I cannot seem to figure it out, and maybe it is not possible, but I would like to do something like:
FOREACH Month As TimeSpan in ContractRange.Months
Do Calculations (Month.Start, Month.End)
NEXT
Is this possible or do I need to calculate the number of months, and just iterate through the amount of months and calculate the start/end of that month based on my index?

I want to create a Timer such that I can reset the time to say 00:00:00 (hrs:mins:sec) and be able to stop, reset and start the timer as needed. I have actually created one from the scratch but it seems like it is long on code. Any ideas on how best to do this?Only performance counts!

I've done what I thought was a lot of work with DateTime and Timespan but what I am trying to do now I cannot figure out. It seems simple enough but I can't think of the code I need to make it work >.<
Currently I am using a timer to tic on 1000ms to count down a timespan. However, what I would like to do is set a timer for 30 minutes. I would like to display the minutes:seconds of the timer on a label and perform actions when the minutes and seconds are specific values, say minutes = 5 AND seconds = 0 to perform an action when the timer reaches 5 minutes exactly.
My goal is to have a 30 minute timer that performs actions at specific times, then when the timer reaches 0:00 it restarts at 30:00 This seems like such a simple task but I cannot for the life of me figure out where to start.

after reading a topic that Chris Rutland wrote about student in final year (link)[URL]...So i was able to complete this in roughly 15 Mins give or take. it also said multiples of three and five. Which i would have understood as 3 * 3, 5*5 as so on, but when I thought about it they would never match within 1 - 100 so I took I must have misunderstood so I then done it as 3 + 3 and 5 + 5 and so on. Which would then give matches for FizzBuzz. So my question is from my code below what would you do different. Could any of you write this with less lines and if so how.

What I want is: To scan a website every 15 mins or so, (craigslist in this case), and email myself any new posts that come up. I know I need to use WebClient, but I never used that before. Another question would be how to only email when a new post is up and not receive the same email every 15 mins.

I don't know the word for this in english, but I want less number behind the comma in a timespan. This is because I generate a report for the user which shows the value of a timespan. But 00:05:01:230000 is not really necessary for the user. It will just confuse him/her.
Is it possible to remove all miliseconds?

I tried to parse string to TimeSpan like the following :
Dim dt As DateTime = DateTime.Now
Dim timeCheckin As String = Format(dt, "HH:MM:FF")
ts = TimeSpan.Parse(timeCheckin)
It threw error like this:
System.OverflowException: The TimeSpan could not be parsed because at least one of the hours, minutes, or seconds components is outside its valid range.
