My company have many DFG files, that represents the diferents buildings of the company.  My question is, How can I use that maps/files in a ASP.Net aplication to show the files and if I can use some api to read text, or to paint diferents Objects (like a control pannel) in the file.

Im using VS2008 C# 3.5 SP1 Framework.

Does someone knows if exists a tutoria to develop that kind of things.

Thanks.
