I created a VB6 program that could open a file with a custom file extension (******.msw). Windows recognizes the msw only when I manually set it up in the file options--file types. This would be hassled for me to do if I am distributing the program to many users. How can I make this setup automated when the users install the program? Is there a way to do in VB code or need to configure in the Package and Deployment Wizard??? Thanks!
