Global database connection VB script
Hi
I have made a database connection (works great) :
<%@ import Namespace="System.Data" %>
<%@ import Namespace="System.Data.SQL
Sub page_load
Dim connection as New SQLConnection("Server=Serv
connection.Open
Dim query as String = "SELECT * FROM news ORDER BY ID DESC"
Dim command as New SQLCommand(query, connection)
Dim dataReader as SQLDataReader
dataReader = command.ExecuteReader(Comm
dataGrid.DataSource = dataReader
dataGrid.DataBind()
connection.Close()
end sub
how to make this a global function?

Hi damixa,
You can create a separate project (data access layer), class library in which you can use this method and expose other data-access methods as public module. Then you can add references to this library from all your other projects using the same database.
A good alternative would be to use the Data Access application block that you can easily find on internet.
Cheers!

or without decalring the Namespace...Like this:
Public Class MyFunctions
Public Shared Function TestString() As String
Return "Hello"
End Function
End Class
and call your function like this:
Response.Write(MyFunction.
Public Class MyFunctions
Public Shared Function TestString() As String
Return "Hello"
End Function
End Class
and call your function like this:
Response.Write(MyFunction.

Don’t know how to compile a class file…
aki4u:
gets an error, I think class1.vb needs to be imported in WebForm1.aspx

You need to create new class...in VS IDE right click on project(second one from top)->Add->Add Class
Follow my instructions and you'll be ok.

Name 'myFunction' is not declared.
ASKER
dataGrid.DataSource = class1.myFunction()
Works..
But I don’t get any data returned

Finally it works....
It was a problem with my page_load… :)
The first problem was: I was using web matrix and .net 1.1.
I have found VS2005 web dev. Express 2005 (free version) much better
Thanks a lot!!

To make this a global function
Step1 Create a class library project and add this function to that project
Step 2 Compile the library and add the reference of new DLL to your project
I would also suggest to store the connection string in web.config file
