Can the Regex code be placed into a class?
The following sample program comes with the Boost Regex distribution. It compiles and runs fine. Its purpose is to count the number of classes in the input text file. http://patriot.net/~ramon/regex_iterator_example.cpp.txt I am having a real hard time trying to convert the code to a class (named "Pairs"). The compilation problem occurs in this statement: std::for_each(m1, m2, ®ex_callback); The compiler suggests to use this statement, which does not compile either: std::for_each(m1, m2, &Pairs::regex_callback); Thanks, -Ramon http://www.parashift.com/c++-faq-lite/pointers-to-members.html

Is regex_callback a member function? If so you will need to "bind" it to an object instance (using std::bind1st and std::mem_fun for example, see also regex_grep_example_3.cpp). HTH, John.
