Write From Javascript To MSSQL?
Jun 27, 2012
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.

I 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?

Dim connetionString As String
Dim cnn As OleDbConnection
connetionString = "Provider=SQLOLEDB; Data Source=****; Initial Catalog=****; User ID=***; Password='****';"
cnn = New OleDbConnection(connetionString)
Try
cnn.Open()

I have been working with this for awhile, and I can't get it to work, I have all the correct names where the connection string is, but I just can't get it to work. It is telling me the server does not exist, but I am using a hosted solution that I know is up.

We are trying to view reports with MS SQL 2008 reporting services for a custom web application.We have MS SQL 2008 Express full install. We've tested the application from our IDE and it works. Once published to the web server we get the following error:
404 - File or directory not found.The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.I syuspect this may have something to to with IIS 7.0 setting, since it works in the IDE but not on the server, but I have been unable to figure out what the issue is.Here is our code.[code].....

I'm watching tutorials about creating Web Site and about controls.I think I added SQL Database to the project (it's not empty) properly. 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? Should I read about ADO.NET and use something from there?Later I want to use VB for work with that strings.

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.
