So I can't figure out how to find the first day of the week. I also need it in a format like ("yyyyMMdd")
Right now I only have it telling me its Sunday. I need the exact date.
Dim FDW As Date
FDW = WeekdayName(1, FirstDayOfWeek.System)
MessageBox.Show(FDW)

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.

I 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

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)

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)

I am writing a windows application in VB.Net.
My client wants an intelligent combo box with type ahead capability. For example let's I have a list of companies. I want to find my company "MetaPro". With the Microsoft combo box if you type in the first letter of the name it will bring up first one starting with that letter. For example I type in "M" it will bring up "Mass. Dept. of Ed.", I then type in "E" I get the first one starting with "E" maybe "E, G & G" where I want the first one starting with "ME".
Perhaps there is an open source solution to this or I could create a custom control. But I don't know how.

Got a problem that's hopefully a quick fix. I've got a homework assignment where I have to link an access database file and allow the user to go through the records, add/delete records and save the file.
When I run the program everything seems to work fine, except when I hit the next button to go to the next record, it always skips 2 ahead, from 1 to 3 and 3 to 5. The previous does it also and when I click the delete it deletes 2 records. I can't figure out why it's doing this. The table we linked was already created for us so I don't believe that it is a problem with that. One weird thing I noticed is that it shows that there are 5 records so I wouldn't think that it is seeing 2 as 1.
Here is my code for the buttons:

way to write the LINQ query. The parent class is simply a student's name and a list of test score data. The child class is a single test score datum. I want to find the worst (or best) score out of all of the TestScore values and then identify the student who had the best score.
Dim query = From s In studentList _
Where s.ScoreList.Select(Function(d) d.TestScore).Min _
= studentList.SelectMany(Function(g) g.ScoreList).Select(Function(h)

I have a problem finding strings that do not exist in a column in a database. I am going to use linq but its more the 'way' of doing I am concerned with.
I have strings like;
MEAL
GPST
EXLEG
EXLG ...etc
I need to find records that does not have this list of strings in, so for example DBML BUT sometimes I can have the string MEALDBML, or more concatenated. So this is a known string of MEAL and unknown string of DBML. I would then want to see that record. I do not know the unknown strings up front, so its a case of feeding in the strings I know are ok, and finding one that are outside that list. I was also thinking of regex?

I need to do a query in which I can find all records in a table in which a user enters a search word. The word to be searched for will be a word in a column. If there's a table named solutions and in the table there is a field named description; i need to be able to pull up all records where for example the search word is 'printer' is in the description column. I don't have any code or database structure to show. I first need to know if this can be done. Can someone supply a code snippet example or tell me what SQL keywords will do this, or some pointer?

I have users check off lab facilities in a UI. I want to use linq to fetch corresponding records for all of the labs that they have checked off. Basically,
Dim myRecs = (From l As EpiData In myDataContext.EPIDatas Where l.facility= _
one of the checked labs
So basically, I need to write a linq query where the "strings" to match are determined at runtime. Is there any way to do this easily? I know that there is a library out there called dynamic LINQ, but (1) it's in C# and I'm writing in VB (2) I'm really just looking for a single, simple solution for this single case.

This seems like it should be something very easy to do, but every time I approach this issue, I end up w/ solutions that feel "less than elegant" Here is my basic question: If I am looping through a dictionary that I have ordered in a particular way, within any given point in the loop how can I "peek" or get reference to a dictionary item 'x' places ahead of the current item without changing the current enumerator? For instance:
Dim tempDictionary = New Dictionary(Of String, String)
tempDictionary.Add("TestName1", "TestValue1")
tempDictionary.Add("TestName2", "TestValue2")
tempDictionary.Add("TestName3", "TestValue3")

Sorry in advance. I emailed myself my coding since I don't have vb on my personal computer. Sooo, the format is going to be off. But my program allows the computer to generate a random date. The user has to guess what day of the week the random date lands on. I have written the whole code. It all works except when user checks his/her answer. The answer always comes up as incorrect. Here is the coding:

I have a ComboBox where I select which day of the week I want it to update. And each week at that day, at a predefined time as well I want it to add 1 to an integer. I want it to continue doing this until I stop it. When I close the program I want it to do a check on start up if it has past that set date and time, if it has it should add 1 to the integer again, if 2 weeks have past I want it to add 2 to the integer.
