Assign Integer Values To The Items In 2 Different List Boxes Called LstWorkshop And LstLocation?
Apr 18, 2009I am trying to assign integer values to the items in 2 different list boxes called lstWorkshop and lstLocation. I then want the equation, intCost = intDays * intLodgingFee + intRegistrationFee, to be executed and the result to be displayed in a third listbox named lstCost. This is what I have so far, but whenever I run the program the value that always gets displayed is 0, which is obviously not correct.

Getting Field Values From A List Into Fields In A Structure Or Class?
Mar 21, 2012I have a class (using a class rather than a structure only because I can set a default field value for the fields I declare in the class) and I'm using a web service that returns information (demographic information) in JSON. I am using LINQ to get the values of each "entry" from the returned list and in that, I have to parse through and pull out the actual data that I want.Here's how I have it doing right now (just a start, there are 44 of them total, thus my question which will follow the code):
Dim returnedStats = From ljo As Linq.JObject In returnedObject.SelectToken("results")
'
'
For Each stat As Linq.JObject In returnedStats

View 3 RepliesSql Server - Linq - Limit List To 1 Row Per Unique Values Based On Value (minimum) Of Single Field
May 3, 2012I have a stored procedure (I cannot edit) that I am calling via linq.
The stored procedure returns values (more complex but important data below):
Customer Stock Item Date Price Priority Qty
--------------------------------------------------------
CUST1 TAP 01-04-2012 £30 30 1 - 30
CUST1 TAP 05-04-2012 £33 30 1 - 30
CUST1 TAP 01-04-2012 £29 20 31 - 99
CUST1 TAP 01-04-2012 £28 10 1 - 30
I am trying to limit this list to rows which have unique Dates and unique quantities in LINQ. I want to remove items with the HIGHER priority leaving rows with unique dates and qty's.
I have tried several group by's using Max and order by's but have not been able to get a result.
Is there any way to do this via linq?
EDIT:
Managed to convert brad-rem's answer into VB.net.
Syntax below if anyone needs it:
returnlist = (From p In returnlist
Order By p.Qty Ascending, p.Priority
Group By AllGrp = p.Date, p.Qty Into g = Group
Select g.First).ToList

Auto-assign Number To SQL Field?
Jan 12, 2010Probably a simple question for most of you. I'm putting members of a group into a SQL Database so we can better manage attendance and 'points' that they earn for doing work. I've written the program in VB and have the SQL server running fine. However, I have created a separate table to handle the points and have marked the relationship between the table - the column is named 'PointID', and should be unique for each person. When I add a new user to the database, I want it to automatically assign a value to that without me having to do anything extra beyond pressing save. From this PointID, it should identify the user and it will bring up the person's points.
