Hey all... the other day I downloaded a registry class from another question on EE. However, it is not working. I am trying to use the CreateEXEAssociation function but it is not working. I made a CreateEXEAssociationOnNT function based on what I found was created in the registry when I used Explore to create the assoitation. It writes the correct keys to the registry but it will not write the data to the default vaules. I have tried a couple of different things, but nothing works. The module is in a comment below. I am currently using NT 4.0 SP4, but I would like this to work with 95 and 98 also. Thanks.
