Is there a method or function that I can use to get the number of days between a start date and end date? I tried using Timespan, but I was noyt able to convert the value to a string. What I am doing is I have 3 text boxes. 1 with start date value user will set using a calendar. And another with end date set using a calendar.And the 3rd text box is being used to display that difference between the two dates.
View 3 RepliesI have a date in the future e.g. 13/10/2008 I need to subtract the current date (today is the 28/09/2010) minus 7 days, so thats 21/09/2010 minus 13/10/2008, which would equal erm, 720 something ? But the current date won't always be 28/09/2010, obviously. I need the code for this. EDIT: When i said future I mean past :)
View 3 RepliesI read that .Net has no function equivalent to Excel's "Workdays" function, which adds a specified number of workdays to a startdate, including an array of holidays. I managed to find a function that adds the number of workdays to the startdate, but I am having no luck telling the function to add a day to the start date for each holiday within the date range. I've pasted a self-contained function below. Every time I compare the result against the Excel result, it's not adding up.
Private Function CalcEndWD_5wkd(StartDate As Date, WD As Integer) As Date
Dim Holidays(23) As Date
Holidays(0) = #10/5/2012#
Holidays(1) = #11/12/2012#
Holidays(2) = #11/21/2012#

I can do this on the SQL side or the code side. I have Linq at my disposal if I need it. The table doesn't need to be compiled by SQL. This will happen dynamically on a website and should be as efficient as possible.I don't want to have to iterate through each and look for breaks in contiguous days if I don't have to.
I am supost to code a program for my homework using an one-dimensional array.in the program you enter the number of the moth and it gives you how many days are in that month. and I'm just kind of lost?
