Jan 19, 2011I have an application that needs to read data from a view and do some extensive manipulation prior to delivering it to a chart control (without modifying the original data in the database).

DataSource Controls :: Access Data Returned In Dataset?
Feb 26, 2010I am having some difficulties with a particular task. I am creating a support desk intranet application and I am trying to write a method within a class within a namespace which will form a generic database connection which can be called from any of the aspx pages so that I have the dbconnection logic in one place; you know, going along with the 'DRY' (Don't Repeat Yourself) mantra.
The Namespace:
SUPPORTDESK.SQL.dbconnection.pullData()
Objective of the method:
To provide any aspx code behind file with an SQL Server 2005 Express Connection and if possible return the data from an SQL Query. This is where I need advice do I create the method such that it simply forms the connection and returns a DataSet or that it returns an SQLConnection object? If i've got things back to front and upside down don't worry I'm a beginner with ASP.NET. The Method so far:

DataSource Controls :: Querying & Updating Data From Dataset?
Mar 15, 2010I'm hoping someone can point me in the right direction. I will be as detailed as I can in explaining the issue;I have a dataset I have instantiated in a class file (vb.net), and fill the data succesfully. That data is then dumped into an excel file. What I need to do is to go through all the data in the dataset, and directly update the database, changing a "status" column from "pending" to "processing" based on the store number. As I am new to datasets (relatively speaking, of course), I am not quite certain how to accomplish this task. Below is the code I have so far:
