Again, thanx to all who replied,
I wanted to stay away from querying the registry continuously as it
not only noticeably slows down this operation but the more times I run it
the slower it seems to get! Anyone else seen this with the registry?
Anyway, I'm updating an app I wrote some time back for a guy and
wanted to automate this part of it. It basically provides file launching
and in the original version the user made a choice at the time a file is
added to the launcher if it should be made to run as a filename or a
parameter. If the latter, the user could then decide to run it using its
registered application or a named secondary application. If it was a data
file this works great but if an exe or some other stand-alone type it was
confusing. The various methods for checking if it had a registered
application and if so what its path and name is was too slow, so I
considered building my own list when a file is used the first time. That
was much faster, but the user still was faced with making a decision for
each file. So finally I decided to store a string of delimited stand-alone
file-extensions and check against it when the file is being used. If not
one of these types it gets used as a parameter, otherwise it goes in as a
filename. This is a much shorter list and a lot faster, plus new types can
be added to the list by the user anytime wanted.

Oh... I forgot.
The registry path where this association is keep, is HKey_classes_root.
