.net - Do A Foreach On A TimeSpan By Timespan Type
Apr 26, 2010I 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?

.net - Formatting A Negative TimeSpan?
Jul 11, 2010I'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.

Change The Format Of A TimeSpan Property?
Jan 15, 2009I have the following code, and I want it to act as a stopwatch.

spn = spn.Add(New TimeSpan(0, 0, 1))

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.)?
Convert A Timespan To Hours And Minutes?
May 14, 2009I am working on a timekeeping application in VB 2008 and need to show elapsed time in hours and minutes.

Is there a better way then using code like:
strHours = (TimeSpan.Days * 24) + TimeSpan.Hours
strMinutes = TimeSpan.Minutes
strTotalTime = strHours & ":" & strMinutes
Convert Double To A Timespan (date)
Sep 23, 2009Let just say I have an Integer like 10,000 (that's the VALUE in want to reach). So, I have another integer like 2500 (that's my current VALUE). Third I have another Integer about 350 PER HOUR. To reach 10,000 I need 7,500 (well I already have 2,500). How long must I wait to reach the 10,000 when the increase is about 350 a Hour. Okay, that's easy: 7,500 / 350 = 21,428571 Hours. BUT how can I convert this double to a timespan? Or how is it possible to add this double value to the current Date to get the Date + Time when I reach the Value?

Removing Item From TimeSpan List?
Sep 26, 2010I'm trying to remove an item from a TimeSpan list but I need a TimeSpan for the index? If I use a List(Of String) it works fine if I use an integer for the index, but if I use List(Of TimeSpan) it wants a TimeSpan for the index. I have declared a variable like so:
vb
Dim TempTime, TimeRemover As List(Of TimeSpan)
but when I try to remove an item from the timespan it says it needs a Timespan and not an integer. Say I have:
vb
For x = 0 To 3TempTime.Remove(x)Next
That doesn't work, but if I have:
vb
For x = 0 To 3TempTime.Remove(TimeRemover)Next
It will work How can I just remove an item from a TimeSpan list?
EDIT: Figured it out, RemoveAt was what I was looking for.
