i tying integrate ontology ontologies. did importing ontologies in protege, works, protege lists classes, normally. looking if there way in reference (uri) of these ontologies , can use them prefix. ofc, building ontology using owl2 i hope me if want reason , materialise facts based on terms relating referenced concept, need import ontology referenced concept belongs. e.g given external ontology following statements: ex:person owl:class; rdfs:subclassof ex:agent. if reference in without importing: ex2:doctor owl:class; rdfs:subclassof ex:person. and make following statement: ex2:jack ex2:doctor. an run through reasoner, materialise following: ex2:jack ex:person. but not following: ex2:jack ex:agent. to materialise latter, need import ontology statements ex:person.

char arbc[60]; cout << "message: "; cin.getline(arbc+'\0',sizeof(arbc)+1); system("pause"); postmessage(hwndch,wm_settext,(wparam)*arbc,0); so hwndch window child , child textbox, it's parent main window form. problem wm_settext isn't setting text of textbox string of characters. know it's not problem windowchild because wm_char outputs @ least 1 character in textbox. note: i'm modifying handles of process. you cannot use postmessage wm_settext . that's synchronous message. problem greater when window in different process. system needs marshal text process process. cannot asynchronous message. use sendmessage instead. your other problems include @ least following: the wparam argument wrong. parameter ignored. pass (lparam)arbc lparam instead. documentation quite clear. you should not use c strings in case. use std::string , , c_str() . your use of sizeof wrong. use of getline wrong too. you seem conf...
