Hi there,
Does anyone know how we can PROGRAMMATICALLY change the program used to open
a file? I am using vb.net. Any help will be gratly appreciated!!

You mean like if at one point if you click on a jpg it opens Paint, and then
you make a change and then a jpg opens to Adobe?

That would be a registry entry that you can manipulate

Thanks for your help. To be specific, my case is that I have a 3rd party zip
application that creates a .cmp file. When a user downloads this .cmp file, I
have a utility to expand this file. So when a user double clicks on the .cmp
file, I want it to open with my .exe to unzip. Any ideas on how can I do this?
