Hi friends,
While saving a file in Windows Environment from my rich text box, I want to create a separate file type for my application which other applications cannot read. I am currently working in Visual Studio 2008. Please help...

This is really basic. What have you tried? What isn't working as expected?

The only way to do this would be to use encryption.

If you change the file extension without encryption, the user initially wont be able to open the file.
However, once he associates the file to a program in Windows, he can open the file using that program any time.

Create a binary file with an extension for your application. It won't necessarily prevent other applications form opening it but only your app will be able to read the format.
