am using sql 2005 and vb 2008.i need to compare dates and select matching records betweem a selected date range.say records between 11/13/2010 and 11/20/2010.e.thing is working ok except when it comes to selecting dates between 11/1/2010 and 11/9/2010.this is happening because when am retrieving the dates from database,its being retrieved in the format 11/01/2010 instead of 11/1/2010 and so it reports no records found,and knowing the limits of sql 2005 this is the only way i can retrieve the date.

Writing a little program for my wife and thought it would be cool to have the calendar auto select the next day of her choice when she opens it. Example it's Monday and she opens the program to make notes about things for her girly get together every Thursday. Right now she opens it and has to select the next Thursday first to get the date.
What i thought would be cool is if the program picks the next Thursday for her, in the future the night may change to Tuesday so i don't mind hard coding the selection for now as it wont change all the time.Is there an easy calendar or date picker routine available for this or is it a roll up the sleeves, i searched and not finding anything.

LVProducts is a Listview and DS is a dataset

The problem that I'm having is that when I try to select a different date, the text doesn't go away. That may make no sence, but let me tell y'all what I've done.
1: Created a GroupBox
2: Put a DateTimePicker in the GroupBox
3: Put TextBoxs in the GroupBox
4: Changed the DateTimePicker to look like this:
A)Checked - False
B)Allow Drop - True
I thought that if I changed that, then the text in the text box would go to that specific date. It didn't do that, it just stays the same. What I'm trying to do is enter text in say 3/7/11 and when I choose date 6/12/12 it will display blank text boxes for me to enter something different.
I have problem and I've been looking for a week now on how to solve it. Yesterday I thought I solved but apparently I didn't when I tried the query with new data added in my database.Here's my query
Public Function getTicketsByBeginstation(ByVal station As String) As Array
Dim r As Array
r = (From u In treinDataContext.Tickets Where u.ritId =[code].....
The problem I have is: when I have a station selected there are more than 1 trajecten (connections in English) but I had to use the .first else Visual Studio would give the error "the '=' operator is not defined for 'integers' and 'system.linq. IQueryable(of integer)".
So I give the name of a station -> I have to select all trajectens with the given station as beginstation -> I have to select all ritten which have the given trajecten -> I have to select all tickets which have the given ritten So: I have to show all tickets for a certain station.
I have a form with controls on it which are binded to a table, I have records selecters and so on... Just a simple display and edit form(yes I also want to be able to edit them so...) I created this form just by dragging items from the Data sources window.
Now I want to add a combobox which has a list of titles. And here comes the difficult part: When I select a title in the combobox, all the other controls show the matching info(matching to the title), in other words the datatable which is attached/binded to the controls must move to the right record. I have added a query to the combobox , which has two columns: ID and Title. the displaymember is Title and the Valuemember is ID. So I must look in the datatable for the right ID.
I have problems retrieving records for a particular day. And is kind of urgent now. I'm using DateTimePicker1 & DateTimePicker2 to let the user choose the date.

How should I do it?

I just want to select 1 random record from my database for example in my table1 i have a,b,c,d,e,f,g then everytime i click the button in my program it will output randomly between a to g then i can add another record from my database and if I make it a to x it will randomly choose between a to x, the random doesnt have any conditions.
Right now i've found some codes that will be very useful but i cant modify it so it will be connected to my database.

I have a search form that has the ability to return many records. I would like to have the results generated in such a way that a user can select one of the records.An example:
John Doe
Jane Doe

If the user specifically wants to look at Jane Doe, then that record would be pulled and put into a new form. How can I make the records selectable especially when I don't know how many will be returned on the search.
I've got a table that caches calculated values for certain dates. I want to use LINQ to select all rows where the calculated value fields are null.But when I use isNothing I get an error that LINQ can't translate this into T-SQL. Is there a way to select null values with link, like this...?
Dim var = From rec As Record In myDataContext.Records Where IsNothing(rec.calculatedValue) Select rec
Other posts on stackoverflow mostly discuss how to avoid or check for null values with LINQ.
Note: I can't just set cacluatedValue's default to -1 to flag records whose calculated value has not been set (and then select those records) because I run queries that sum/average the calculated values. Selecting nulls seems cleaner and less bug-prone.
The following code throws an error on saving a record: "Conversion from string "TDT" to type 'Integer' is not valid" The following code is highlighted:

Here's my current query that gives the result like the image below:
Dim db As New DBDataContext
Dim query = From st In db.Students _
Join c In db.Countries On c.Id Equals st.Id _
Join r In db.Rooms On r.Id Equals st.RoomId _

current query result I got only one result back because I have (2) William NoMan record in every table.

I used following code searching records from a table in MsAccess and displaying in a Listview and it is working fine with the search criteria based on Discription.
CODE:
I also tried the above code to search records on the base of CustId and it worked fine too.My table DailyTransaction in MsAccess is as under:DTDate, DTTime, CustId, Description, Quantity, Price, Amount, AccountNumber, Name
Now I want to Search records on the base of Date I tried the following but it did not work.
Dim cmdText As String = "SELECT * FROM DailyTransaction WHERE DTDate=' " & TextBox1.Text & " ' "
Also i want to make following sort of query to retrieve data between two dates and to display the sum of amount group by DTDate. I could sketch following query and deifinitely it is so wrong with Syntex.Select * From DailyTransaction where DTDate Between textbox1.text AND textbox2.text Group By DTDate AND SUM(Amount)
