Accessing Oracle forms

Hi, I have an Oracle Developer form which can be viewed at . The textbox of that Oracle form should be dynamically updated with a value from my C# code. I'm a newbie to Oracle Developer forms. So, I would appreiate if you can shed some light on how to access the fields of the Oracle Developer form using .NET code. I mean how does an Oracle Developer form publish itself? What is the interface. Any help is greatly appreciated. -Srivalli.
