I need to find the date of Monday this week programmatically.For example, for this week Monday was on the 9th, so the date I need is: 09/11/2009.And when we roll over to next week it needs to calculate: 16/11/2009..I have tried doing this myself but I can't see how to do the arithmetic.

I need to find a way to find the date (DD/MM/YYYY) of the Monday for any week we're on.
For example, for this week, monday would be 09/11/2009, and if this were next week it'd be 16/11/2009.
I managed to get somewhere in the forms of code, but all I got was 'cannot convert to Integer' errors. I was using Date.Today and AddDays().
I had some trouble specifying Monday as the first day of week in the DateDiff function.
The following syntax does not work: Dim myWeekNumber as Int32 = DateDiff("ww",date1,date2,2)
Compiler Error Message: BC30519: Overload resolution failed because no accessible 'DateDiff' can be called without a narrowing conversion
However, using the enumeration value (FirstDayOfWeek.Monday) instead of the value (2) does work. I wonder why.
I have a two buttons: Previous Week & Next Week When i run the app the LabelDate needs to shows up "May 31, 2010 - June 6, 2010" When i click a previous week button i want to set LabelDate's text to "May 24, 2010 - May 30, 2010" If i click Next Week button i want it shows up "June 7, 2010 - June 13, 2010" Means it should always display previous/next week starting from Monday and ending with Sunday.
View 4 RepliesI have two datetimepicker controls now when I select February 22, 2010 from datetimepicker1 which is Monday I want the other datetimepicker2 to be February 25, 2010 which is Thursday. This means that I want datepicker2 to automatically look for the Thursday value of the week. I have set my week start day as Saturday and ends on Thursday, Friday is holiday.
Sample
Datetimpicker1 Datetimepicker2
02/20/2010 02/25/2010
02/21/2010 02/25/2010
02/25/2010 02/25/2010
How can I find the date of the Sunday of the first full week of a year using the DatePart function or something else? Jan 4 for 2009.
View 3 RepliesI 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)

How can i find the week number in a month.
A month can have 5 weeks, i need to know in which week i am.
I am trying to determine how to take a date and show what the week number is for that month. So 3/1/10 will be week 1, 3/16/10 will be week 3 and 3/30/10 will be week 5. I know how to get the week of the year number just not week of the month.
View 4 Repliesis 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)

View 1 Replieslets say i have a string that holds "Monday" and another string that holds "9:45:00 PM". would it be possible to look at the Date.Now() function and see when the next Monday is, and then convert those two strings into a date? lets say the next monday was 05/20/2011. I would want the date variable to hold "05/20/2011 9:45:00 PM". any ideas guys?

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?

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.

Dim d As Date = CDate(mtbDateOfBirth.Text)
txtBox2.Text =

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.
In regular SQL i could do something like
SELECT * From T GROUP BY DATEPART(wk, T.Date)
How can i do that in Linq to SQL ?
The following don't work
From F In DB.T Group R By DatePart(DateInterval.WeekOfYear, F.Date)
Also don't work:
From F In DB.T Group R By (F.Date.DayOfYear / 7)
So there's this accounting package at my client that spits out text-based reports with invalid dates, like February 31st or September 31st.The reports are formatted with spaces and mono-spaced fonts. The data that gets parsed out are fed into a more formal local SSRS report, and that's about all you need to know.
What I am interested in fixing is the situation where a date is invalid and can't be converted into a DateTime struct. The date format from the report is "MMM-dd-yy" (e.g. "Feb-30-10"). The date strings need to be fixed before being shown in the formal report. I've seen this done two ways in my time as a developer, and I want to come up with a cleverer way of doing it (if there isn't a built-in way I don't know about).The first bad method (I can't believe I'm even showing you!):
Dim month As Integer = <Parse out the month from the bad date string>
Dim day As Integer = <Parse out the day from the bad date string>
Dim year As Integer = <Parse out the year from the bad date string>
Dim validDate As DateTime

It is a requirement that all .net Controls are created on the main thread, at least this is necessary if the intent is to integrate the control in with the interface which is usually the case. Additionally to modify properties on the control one must invoke the method from the control's thread using its own invoke method.
Is there a way to look at a control and identify its owning thread directly?
Additionally or conversely, is it possible to detect whether the current thread is the "Main thread"? Is there anything special about the thread that Visual Studio identifies as the main thread that can be seen at runtime, or is it simply that this is the first thread that VS executes to initialise debugging?
