Calculate The Start And End Date Of A Week Given The Week Number And Year In C# (based On The ISO Specification)?

Aug 4, 2009

I need to generate a report that shows the 52 weeks of a year (or 53 weeks as some years have) and their start and end dates. There is an ISO spec to do this but seems awfully complicated! Im hoping someone knows of a way to do it in C# or Visual Basic (its actually for Visual Basic 6 but I will try port it across)

Get A Date Based Off A Week Number?

Jun 3, 2010

Given a week number, I need to get the date of the Monday of that week.For example, I have several strings that are stored in a file, such as

"WK 28 2010"
"WK 30 2010"

They could be any any valid week number.

The Monday on Week 28 of the year is 12 July 2010
The Monday on Week 30 of the year is 26 July 2010
Its these dates that I need.

I guess I could create a lookup table, but would prefer a more smarter approach so my software will be future compatible?

is there a simple builtin function that i could use to get a date instance from a calendarweek/year-combination?

It should be possible to enter 10w2005 into a TextBox and i'll create the date 07 March 2005 from it.

Monday should be first day and CalendarWeekRule should be FirstFullWeek.

My first approach was:

Dim w As Int32 = 10
Dim y As Int32 = 2005
Dim d As New Date(y, 1, 1)

VS 2010 - Request User Date Of Birth And Display Day Of Week

Feb 2, 2011

I am in a VB 2010 class right now, and I'm suppose to write a program that requests the user's date of birth and then display the day of the week (such as Sunday, Monday, ect...) on which day they will have or had their 21st. Birthday.

I already have the GUI made up with a MaskedTextBox set to simple date and it is named = mtbDayOfBirth
I also have the button already to calculate this, and a read only text box named = txtBox2.

My code so far is:
Private Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim d As Date = CDate(mtbDateOfBirth.Text)
txtBox2.Text =
End Sub
End Class

The only thing in my book only talks about how to pull the number of days from your bday or pull the full birthday as like the 04/06/1992 would return Monday, April 06, 1992.
