Unless you are not willing to use any fancy database approach and run some queries, you could go for an ASCII file, in which each line could contain text like:
22-Namewhere the id is followed by a "-" and the name itself. Then you use aCStdioFileobject to read the file line by line. Assuming now that you get the line info into somechar chText[256]variable, you go then for something like this:char chName[256]; unsigned int ID; sscanf(chText, "%u-%s", &ID, chName);As soon you get the ID value you are looking for, you stop the process of reading the file, close the file and returnchNameI'm pretty sure, some other ways exist as well :-)) SkyWalker -

In Continuation with Mr. Puiu, if you like to have light Database approach .... you can try embedded database like Sqlite:- here is an article related to it :- http://www.codeproject.com/database/vmembedded_db_cpp.asp[^] http://www.codeproject.com/database/CppSQLite.asp[^]
