I know the datediff function can give the count of the number of days between two different dates, but how can I get the count of the number of business days - i.e. Monday - Friday - between two dates?
View 2 RepliesI need to be able to count the number of days a person is on hold. easy enough! However i need to be able to stop the expression when I enter a stop date so it would look like this "start date 1 to today= x amount of days" but i need to be able to add a stop date to end the counter. and if they go down again start date 2 to today and add number of days from start date 1.
View 1 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 4 RepliesI am writing a program that takes a shipdate and generates a timeline of deadlines for a manufacturing job by working backwards from the shipdate. I hav no problem handling weekends. However, some holidays are giving me problems. For holidays that don't have a set date (Thanksgiving, Labor Day, Memorial Day...) what is the best way to determine the date they fall on? Most of the examples I have seen use an array of dates (either from a file or hard coded) for these holidays. Is there a way to do this tha won't require someon to generate a list every year for these holidays?

I 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#

designing a Windows based computer program that will allow a user to enter some number (n) and a choice of a count up or count down for that many numbers. So for example, the user enters 5 as their number and selects the count down option, the message box displayed would contain the message: "Here are your numbers: 5,4,3,2,1,0"

using an object-binding I have a an object representing "Employee". The employee has an ID-property. The ID of the employee must be unique.
My validation of the entered data is handled in the property set part of the object. In general, I validate criteria belonging to the object to validate only (eg numeric range of the ID, if it's value is not empy, ...). But in this case I need to know all ID's from the other employees. My tried this:

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.

How do I calculate the difference between two dates to display as a number in days?I have 2 text boxes (txtHStart_Date & txtHEnd_Date) I have used an Ajax Calendar Extender to enter the dates in each of these text boxes.I would like to get the difference between these two dates to show in a seperate text box (txtNoOfDays)
I've seen the timespan function but can seem to get this to work. I'm not to sure how to declare the text boxes as the dates I would the calculation to be made from
Code:
Dim D1 As Date
Dim D2 As Date
Dim ts As New TimeSpan
D1 = txtHStart_Date.Text
D2 = txtHEnd_Date.Text
ts = D2 - D1
But I know this isn't right. I also don't know how to get it to display in the 3rd TextBox.
