I want to group by the date, these values are now in a dataset. What comes up to my mind is an array list with the following: The master array would have each date listed on the dataset above, within each row of this array I would have the list of numbers for that specific date. How do I do that in VB.NET?
I need to know what would be the best choice of array to use given the following specifications. This array's size will be predermined upon the loading of the appication. All I want to do is be able to add values to this array and replace preexisting array items with new values without the array changing size. Someone suggested that I use a Dictionary Array Object? I would appreciate any suggestions.

I've sucefully created a method to insert values through EF, but i've a question (maybe, a newbie question).
Should i send the values to be inserted as strings to the DAL, and then i create the object there or should i create the object in View Layer and then send him to DAL?
Example 1 (DAL):
[Code]....
Example 1 (View Layer, on a click button for example):
[Code]....
Or should i receive the strings in DAL like this: public bool NoticiasInsert(string tituloPT, string tituloEN, string descricaoPT, string descricaoEN)
Then i create the object cdcModel.noticias and set the fields there with the strings values.
What do you advice me to do? I know that both ways works, but i'm trying to develope with better patterns (i don't know if this is the exacly word, sorry my bad english)
cdcModel.noticias campos = new cdcModel.noticias();
campos.tituloPT = "a";
campos.tituloEN = "b";
campos.descricaoPT = "a";
campos.descricaoEN = "a";
if (DAL.NoticiasInsert(campos)

I am very new to ASP .NET and am getting above error when trying to insert a new record into a SQL database. I have turned on Option Explicit On so the default date of 01/01/1900 does not get assigned to this field automatically. Since most of the people in the database will not have a date of death, I need to have "blank" deathDate. When I run the stored procedure within SQL and choose pass null value, the Insert Procedure works fine. When I attach to Web Form, however, I get String was not recognized as a valid DateTime error. How can I set it so Null values are accepted into this date field.
