I need to write a String Array to a field in a MSSQL Database, however, I'm not sure how to do the connection from javascript to the backend VB.NET to send the data to the DB. Do I need to create a web service and use ajax/json?

I have a little problem regarding the use of DBNull, NULL etc. in VB.net in combination with SQL Server 2k.
More specifically, I want to do something along the lines of this:If x = 0 Then
x = DBNull.Value where x is declared by Dim x as Object. I would rather use Double, but I can't assign DBNull.Value to this, and using Object works quite well, too. But every time I hit this condition, I get an exception: A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll This is not a major show-stopper, since the database value I write x to in the next step, is NULL by default - most of the time! So I need the ability to write NULL to it. If that was not the case, I would have been able to work around this by catching exceptions, I think - but sadly, this isn't really of use then.

View 2 RepliesI am trying to return a javascript function using response.write in an aspx page. The problem is that the function i am returning has lots of quotes and they are conflicting with the repsonse.write syntax. Here is a sample code:
Response.Write(" If hello.StartsWith("H", StringComparison.InvariantCultureIgnoreCase) OrElse hello.StartsWith("W", System.StringComparison.InvariantCultureIgnoreCase) Then")
This is giving me a problem as the quotes inside are cutting off the response early. Is there a better way to do this?

Suppose it has two columns: FirstName, LastName.I have TextBox1, TextBox2 and Button1 on the web site form.I enter any integer number (5, 10, 15 or whatever) into TextBox1. I want to press Button1 and get a value of 5th person (10th, 15th or whatever) from SQL Database into TextBox2.Who can help me with that?

I have one textbox basically the user is going to enter in a 9 digit number or letters. From there I want to have a buttonclick event that validates this against 2 columns in a MSSQL Database. First to check if the number exists, next to check if it is active or inactive.
There are about 27000 rows of numbers so my main question is what is the best approach to handling something like this.
Should I create a view and validate in the click event. Should I create a stored procedure in sql that takes an input parameter and call it in the click event.
I was also reading about storing the information in a dataset however with that many records i am assuming that is going to be a slow process.
