Hello,

I am working on learning about how to make custom file types. I have learned how to register them, and about serializing into a file. I have also created an encrypted file with my own extension that just stores text. However, I have been looking around Google, and here to see if I can find more information about building a custom file type. Not just a text file with a renamed extension. I would like to store information about a report in a file that cannot be read using notepad. Does anyone know of any good tutorials or things online that would give me some in-depth information? If nothing on line, any books that could be recommended would be great, too. I prefer online to start, but if there is a specialized book for just that subject, that would be a good long run tool.

I am currently using Visual Basic 2003, but will be getting 2005 ASAP, so if there is anything that would work for both, that would be great, else 2003 info would be good for now.

Thank you for your help.
