i'd know if possible following: using (myclass o = new myclass()) { theclassiwantmyclasstosee x = new theclassiwantmyclasstosee(); x.dostuff(); } i'd create class (myclass) , use in using block. inside block, want work objects of type (theclassiwantmyclasstosee). when using block falls out of scope, want perform actions on these (theclassiwantmyclasstosee) objects. is possible make class aware of other objects declared in scope transparently? i realise add object instances myclass object, i'd make easier developers working api i'm building. any ideas welcome. thanks. the way make myclass aware of theclassiwantmyclasstosee creating reference 1 other. there no way navigate , explore classes in scope. statement true regardless of whether scope relates using block, method block, foreach loop or other. why not have simple myclass.addrelationship(theclassiwantmyclasstosee child) method makes class a...

possible duplicate: what's difference between path_not_found , name_not_found i error_file_not_found when try open file that's not there, fopen fails error_path_not_found . so difference between error_file_not_found , error_path_not_found ? in winerror.h , error_file_not_found has descriptive text "the system cannot find file specified." , error_path_not_found has descriptive text "the system cannot find path specified." this doesn't particularly clarify matters. usually, however, "file not found" refers case file cannot found , "path not found" refers case component of path (one of directory names specified) cannot found.
