Say I convert some seconds into the TimeSpan object like this:
Dim sec = 1254234568 Dim t As TimeSpan = TimeSpan.FromSeconds(sec)
How do I format the TimeSpan object into a format like the following:
>105hr 56mn 47sec Is there a built-in function or do I need to write a custom function?
I want to format the Timespan to have format like this 49 hr 34 mn 20 sec
I used the String format below :
String.Format("{0:00}:{1:00}:{2:00}", theTimeSpan.TotalHours, theTimeSpan.Minutes, theTimeSpan.Seconds)
It formats the Timespan to this format 49:34:20. How can I add hr mn sec to the String.Format above? or there's another easy way?
I am using a textbox in vb.net but the input should be an hour format for example, "13h30". How can I enfprce this by a user? When he puts the first 2 digits like 13 then automaticly the appl. puts a "h" between?
View 1 RepliesI have the following code, and I want it to act as a stopwatch.
Dim spn As New TimeSpan(0, 0, 0)
Private Sub elapsedtime_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles elapsedtime.Tick
spn = spn.Add(New TimeSpan(0, 0, 1))
Label6.Text = String.Format("{1}:{2}", spn.Hours, spn.Minutes, spn.Seconds)
End Sub
However, when the "stopwatch" ticks, the time is shown like this - 0:3, 2:9, etc. How can I change it so that when the seconds are in the single digits, it shows the time like a normal clock (4:05, 2:09, etc.)?

View 14 RepliesI use a masked textbox, and I would control the input, the problem is, I use 1 textbox and the control should on the first 2 digits with a maximum of 24 and the last 2 digits with a maximum of 60. Is there a possibility to program this?
View 1 RepliesI wrote a VB.NET Windows Service, which works fine. I have only one issue with it. I want the service to execute on the half hour and top of the hour marks (e.g. 9:00, 9:30, 10:00, 10:30, 11:00, etc etc etc). I am using the following code:
Protected Overrides Sub OnStart(ByVal args() As String)
' Add code here to start your service. This method should set things
' in motion so your service can do its work.
[CODE]...
This code works, however, if the service starts at, say, 10:15, then it executes at 10:15, 10:45, 11:15, 11:45. How do I make it so it always executes on the 30 minute and top of the hour marks?
These two TimeSpan are stored in the Database with 24hr format. No date, only TimeSpan.

Is there any TimeSpan method to get this right?
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?
So let's say I have 1400, I want to convert it into 2:00PM I tried the following:Dim convertedTime As String = DateTime.ParseExact(theTime,"HHmm", Nothing)
And it would give me this: 6/12/2012 02:00:00 PM
I do not want the date part, neither do I need the seconds. All I need is 2:00PM
I am working on my program as I have created picturebox1 and splitter1 in my program. I am coding on the if statement as I am trying to compare on the value that if they are less than 184, then do something.
Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click
If Splitter1.Location <= New System.Drawing.Point(184, 0) Then

I know that I can't compare the value using with <= which I will only have to use = instead of <=, but i still want to compare with the value that if it less than 184, then do something.

Suppose I want to add 2 hours to this timespan what would be the method for it + code .
I am not sure if this is oppsiable but i need to subtract from a timespan.
my code is
waittime = toa.Hours - drivetime
toa.hours is a integer can i change it to a decimal
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.

Need to return the greater of 3 values. Each value is based on user input and system calculations. Requirement = the greater of (Req1, Req2, Req3) Have tried a number of "If" "Else" and Ifs within Ifs "<" and ">" combinations without consistant results. This may seem simple to some but I am relatively new to VB. My search on MSDN was not fruitful.

I've written a console utility to set file date/time stamps to a specified date/time:
For Each FoundFile In My.Computer.FileSystem.GetFiles(FileSpecPath, FileIO.SearchOption.SearchTopLevelOnly, WildCards) FileInfo = My.Computer.FileSystem.GetFileInfo(FoundFile) System.IO.File.SetCreationTime(FileInfo.FullName, NewDate) System.IO.File.SetLastWriteTime(FileInfo.FullName, NewDate) System.IO.File.SetLastAccessTime(FileInfo.FullName, NewDate) Console.Write(FileInfo.Name + " " + NewDate)Next
When I go to a command prompt to check the results, the new date is correct, but the hour is off by 1 hour. Same when I check the times in Windows Explorer -- all three times are displayed to the same time, but exactly 1 hour earlier.The system date/time are correct (Vista) and we are not in DST.The files reside on a local drive (not a network share).The computer is not on a domain.
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.
I'm doing some math with the Timespans in .Net, and occasionally the sum results in a negative Timespan. When I display the result I am having trouble formatting it to include the negative indicator.
Dim ts as New Timespan(-10,0,0)
ts.ToString()
This will display "-10:00:00", which is good but I don't want to show the seconds so tried this.
ts.ToString("hh:mm")
This returns "10:00" and has dropped the "-" from the front which is the crux of the issue. My current solution is this:
If(ts < TimeSpan.Zero, "-", "") & ts.ToString("hh:mm")
but I was hoping to accomplish the same by using only the format string.
