bin and app_code problems.

hi all,

new to asp and having problems with bin and app_code folders.

i've a dll that is in a websites "bin" folder and the classes / namespace within it is not being found. as this was the case I figured i'd try putting the code ".vb" direct into a "app_code" folder to make sure it was not the dll.

event that didn't work. now this is a exact copy of a live system that i'm trying to do some work on. the exact same thing works on the other server.

i'm thinking i've missed a setting or something but I cant think what. does anyone have any pointers?? any help would be great.

thanks,

Chris
