attention, RamyMahrous: I'm sorry, I don't understand your comment at all. Are you saying it would be nice to be able to enter the name of a class, etc. to see if some other developer had used that class (or whatever) in a given project?
If you open the exe/DLL it should be able to show you the classes and so on within.. It always seemed very straight forward. What exactly are you struggling with?
You don't say HOW to open the exe/DLL, and there is no meaningful Help within .Net Reflector to tell one this, or anything else for that matter. I'm sorry if I've annoyed you by not knowing something you already know, but isn't the purpose of this forum to learn such things? Anyway, never mind; someone else has since told me this can be done by hitting F3.
Bob - your response could have been, can you tell me how to open exe/DLL ?
Just because someone assumes you know doesn't mean they are trying to be a jerk.
I'm glad you found it, if you have other problems let us know - and mark you post solved so others know as well. (you will find that many of the people here speak over the 'simple' level because they have been doing it for a long time, if you break it down to a smaller level they are more than willing to help as long as your not asking them to code your work for you)
