View 2 RepliesReturning The Exact Date Difference Without Using DateDiff?
Jan 19, 2012I need to return the exact difference between two dates in the form of a string. If the dates are 01-FEB-2012 and 01-FEB-2014, the function should return "2 years" If the dates are 01-FEB-2012 and 01-MAR-2014, the function should return "25 months". If the difference is not in exact years or months, it should return the difference in days. I do not want to use DateDiff from the Visual Basic namespace so the code is portable to C#.

The following syntax does not work: Dim myWeekNumber as Int32 = DateDiff("ww",date1,date2,2)

However, using the enumeration value (FirstDayOfWeek.Monday) instead of the value (2) does work. I wonder why.

View 2 RepliesDateDiff Function Gives Odd Results For Negative Days?
Jun 9, 2009DateDiff 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
Where To Place DateDiff Function To Effect On All Records
Jan 18, 2011I have a project, a database with employee information (name, town, birthday, HireDate, etc). I have add custom TextBox (on fly), and on that TextBox a
TexBox1.text = DateDiff("d", HireDateDateTimePicker.value, Now)
.
Which is calculating how many days worker is working in company from HireDate,and Now.I have put code on event TextBox1_TextChanged. But, this means that I need to move cursor in TextBox1 to apply changes. I have also try with MouseMove. It works, but if I would have a huge database, then application will all the time reading script on MouseMove, and by that will slow down entire program.
Scalar Valued Function - Return Datediff As Decimal / Percent
Jan 4, 2011I am currently writing a scalar valued function and I'm having a few issue with the returned result. I have narrowed the problem down to a calculation that convert the difference between two dates as a percentage/decimal. No matter what I try the return value is always a whole number
set @earnedpremium = (@premium * @pretripearnings) + ((@premium - (@premium * @pretripearnings)) * cast((datediff(day, @outdate, @experiencedate) / datediff(day, @outdate, @returndate))as decimal(5,2)))
The cast section needs to return the percentage, I know the rest is working fine through some elimination and testing.

Dec 3, 2009I recently moved a webservice VB.net project from VS 2005 to VS 2008 and now a conversion I use to create a unique receipt number is no longer working.
The Format() function which is supposedly a Visual basic function gives the error:
'Format' is a type and cannot be used as an expression.
The Year() Function which is also a VB function gives the error:
Name 'Year' is not declared.
The Datetime() Function which is also a VB function gives the error:
'DateTime' is a type and cannot be used as an expression.
The actual code statement remains unchanged between the two web services but VS2005 compiles and VS2008 does not.

Jul 23, 2009i was wondering this: what is the difference as in response.. should i use the .visible or the .show/.hide option.. by setting the .visible to true/false, the controls (in my case) will only appear visible or not.. by setting them to .show./hide, i guess they unload from the form, and reload in their previous state.. do correct me on this .. is this more memory use than the .visible option or the other way? i am currently designing a project containing a lot of panels/buttons/etc., that has the .visible option included for these controls. should i be using the .show/.hide option instead, or does it even make a difference, since i cannot tell from the response of my project when using either/or..
