Javascript - Pass JSON File From ASP.NET To JQuery?
Feb 27, 2012my problem is that my company does not want to serve up the .json MIME type, so I have to use ASP.NET to fetch the JSON file from the file server.

Is there a way I can use ASP.NET (VB) to give the object to my jQuery script after I fetch it?

LINQ - Index Was Outside Bounds Of Array
Feb 6, 2012I currently have a program that uses Linq to read a CSV file. Everything was working great until a recent change was done where the CSV file had records being added to it where the last 2 columns where empty. So, the error I am getting now is Index was outside the bounds of the array. The question I have is how do I handle a column where an empty or null value is set in the CSV file?
Here's my abbreviated code below.

Dim readlines = File.ReadAllLines(strCustomerFile)
File.WriteAllLines(strCustomerFile, readlines.Skip(4).ToArray())

Dim groupedData = (From p In pData _

.net - How To Pass Linq To SQL Types To A Function
Aug 27, 2011The code below is used in a Linq to SQL solution, and is in the Load event of a form. It works fine to display an ordered list of people's names, and set the value member to that person's ID. However, I'm going to be using these 'people' comboboxes a lot, so I'd like to put a sub into my Utility code there is only one line in the form's Load event.
I want to call something like: Call ComboboBoxPeople(cbo, tblTurnbackMain, ReportedByID)
The sub would begin like: Public Sub ComboboxPeople(cbo as Combobox, tbl as 'sometype', fld as 'someothertype')
What can I use as the parameter types for tbl and fld?
