.net - Formatting A Negative TimeSpan?

Jul 11, 2010

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.

VS 2008 Negative Value Showing As 0?

Jun 3, 2011

I have my VB.NET exam tomorrow and I have a list of potential questions, and there is this one question I really fail to find a good explanation for. it gives me this function:

Dim x, y as Single
y=2
y=x+10
MsgBox(x)

it returns 0... and I am supposed to explain what that happened. I have tried changing the numbers so it gives a positive number, and then it works properly... I have tried changing the type too, and still 0.

Check A Value And Make Sure That It Is Not A Negative Number?

I need to check a value and make sure that it is not a negative number using a try catch statement I keep getting an error saying that I have to use a method.

Try
TotalCurrentBalance < 0
Catch ex As Exception
End Try

I wouldn't put a if statement would I? I am thinking that would defeat the purpose.

Looking For .NET Math Method That Will Zero A Negative Integer?

Mar 24, 2010

Similar in concept to Math.Abs() - I'm looking for a function that when given a positive integer will return the same integer. If given a negative, will return zero.

So:
f(3) = 3
f(0) = 0
f(-3) = 0

Yes, this is simple enough to write on my own but I'm wondering if the .NET Math class already has this built in or if the same can be achieved by cleverly chaining a few Math.* calls?

Negative Effects Of Using A Generic Function

Oct 26, 2011

My question here is, what are the negative effects of using a generic function such as this? Calling this function does work, and in a test console module, it compiles perfectly fine. I do know this is not a strongly typed function, and is %100 bad practice. But it works perfectly. The purpose of a function like this, would be to handle string input that needs to be inserted in a particular format depending on the type. I also read some other questions on this here on stackoverflow, and suggestions pointed to using (Of T) functions, and variations like that. Why not do it this way? or is there another simple way of accomplishing this without creating a whole nothing class or larger amounts of code.[code]

VS 2010 Comparing Negative Numbers

Jan 22, 2012

I have this

[Code]...

All that is happening above is two players are being compared by scores and a winner is then decided. The calculation works fine and places the winner in the correct spot (txtWinner1.Text) as long as the numbers are positive. So if txtU1D.Text has 13 and txtU2D.Text has 14...txtU2 is the winner. Works with no problems. However, if txtU1 has -1 and txtU2 has -2...it says txtU2 is the winner. The negative scores are common in the game being played so the situation often happens, but may be one player only. It seems to work if one is positive and one is negative, but if both are negative it thinks the higher negative number is the winner for some reason. So it will give the win to someone who has -9 over someone who is -4.

Why Does A Negative SByte Number Have 16 Bits

Jul 11, 2011

I asked a question earlier about comparing numbers using the "And" comparison operator in If Statements and now I have been toying around with getting my head wrapped around bitwise operators. So I have written a very basic code that will allow me to see the conversion of any decimal number in binary format.[code]Notice here that I am using SByte as the paramerter - which should only contain 8 bits right? However, the message box that appears has 16 bits assigned to negative numbers.

DateDiff Function Gives Odd Results For Negative Days?

Jun 9, 2009

DateDiff for the interval Day gives expected results for days past until present, but if the first date is further in time than the second date, it gives the difference +1. Is there something I'm doing wrong? For example, if I put in today for both, the difference is 0. If I put in yesterday and today, I get 1. This is all expected, but if I put in tomorrow and today, I get 0, and two days from now and today give -1. Why is the function giving altered results if the date is negative?

Here is the specific code.

Private Sub DateTimePicker1_ValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DateTimePicker1.ValueChanged
TextBox1.Text = DateDiff(DateInterval.Day, DateTimePicker1.Value, Date.Now)
End Sub
