file extensions and icons

[seyyah]

I have a program producing several files with different extensions. I am using CFile class to read&write files. I want my files with different extensions have different icons. How can i do this?

Just change in HKEY_CLASSES_ROOT registry key location of the new icon assigned to "your" file extension.

Take a look to shell extension:

Example you can find in chapter Customizing Icons

Good luck
