I am developing a Content management system of sorts and I want it
to be pretty flexible. I have noticed that with web content (News,
Articles, Events, FAQs) that there is a lot of similarity between these
items. They all have the same basic fields:

On the development server, I created a table (still within another database) and I want that table of the development server to contain the data from the table of the production server.

Hello!I am trying to build an application that regularly fetch data (stock-prices) from a third part, which I then present on my site. The hard task, for me at least, is to guarantee that the data the presentation tier use never are truncated.

I want to (and succeeded) read information from one table in my database ([services] in this case) and display them in a table with an additional column with a textbox so that I can enter volumes in it. So far so good, this works fine. But I now want to store all the volumes together with the ID's in a seperate table ([service_volume]) by clicking the Submit button.
Does anyone know how to achieve this?

Hi,Im starting to use iTextSharp to create a PDF file based on the informations filled in my page form. So i created 3 tables to fit the form: One table as header, containing base informations as page number, title of form...
