dear friends
we deployed one application which is used by company staffs also installed
for our agents in many cities.
it is developed by VS.2003 and VB language.
Now i am very worry about our source codes, because i recently heard that
with some programs it is possible to decompile exe and dll files and access
source codes but i am not sure about that.

Please let me know is it possible to decompile .NET, exe and dll files and
access source codes?
if so what should we do to protect it?

Regards

well they don't have the documentation, it's already hard enough.
but people concerned about that usually obfuscate their code.

In visual studio 2005 you have an option to do that.
I don't know about the 2003 version but probably it's there...
