Timer To Run 30 Minutes After The Hour?

Jul 15, 2010

Is it possible to configure the System.Timer to run say 30 minutes after every hour? I have searched google to figure this out but all it shows is how to set it where it goes off once an hour, if I launched the app at 2:45 then it would go off again at 3:45. I can forsee issues down the line with this approach where if it went off at a specified time it would not have that issue.

Normally i would use Scheduled Task for this however it doesn't give you the option for hourly just daily, perhaps i'm wrong about this.

Convert A Timespan To Hours And Minutes?

May 14, 2009

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

Asp.net - Get Difference In Hours/Minutes From Two Date Values?

Apr 11, 2011

I have a date value (e.g. 2011-04-11 07:45:00.000) which I am pulling from my database (via Entity Framework). I need to pull out only the hour from the original date value (e.g. 07:45:00), get the current time, and then subtract the current time from the database time value. In pseudo-code, I'm looking to do something like this:

Dim my_date as DateTime = from_db ' This is the value pulled from the database.Dim this_date as DateTime = Date.Now ' This is pulled via a VB.NET function.Dim my_hour = my_date_but_only_hours ' Somehow, I need to strip the date off the my_date Dim this_hour = this_date_but_only_hours ' Same as line above.Dim hour_difference = my_hour - this_hour Response.Write("There are " & hour_difference & " hours left before the time runs out.")

Display Duration Only Hours:Minutes:Second In Gridview Asp.Net By Using LINQ To SQL?

May 18, 2009

I want to display the duration only Hour, Minutes, and Second in data Gridview by Subtract TimeCheckOut from TimeCheckIn in ASP.NET using LINQ to SQL Here is code behind:

[Code]...

In Line 3 in function, Dim dif as TimeSpan = DateTime.Now.Subtract(Duration) which give only the duration of Hour, Minute, and Second from TimeCheckIn until DateTime.Now. However, I want to have the duration from TimeCheckIn until TimeCheckOut only in Hour, Minute, and Second.

I know that the FieldDisplayDuration function is totally wrong logic, but I just want you to get my point only, and also it could be the code sample for those who want to calculate the duration of the employee from the hire date. Finally, Let's get back to TimeSpan by Subtract TimeCheckOut from TimeCheckIn in gridview problem, How can I do that?

Create A Simple Timer To Count Seconds, Minutes And Hours

Oct 21, 2010

I have three sets of labels, lbl_seconds, lbl_minutes and lbl_hours. These labels have the default value of 00:00 and I want the timer to change that for each label. I have googled this but I cannot seem to find any good info on it. Do I need three separate timers? I have also noticed that the timers have their own tick event handler. I guess it's in this that I need to change the value of the label. But I cannot figure out how to do just that.
