Dear Friend

due to hurry I did sent proper error message so pls have look now.

my program is

typedef std::vectorstd::string vec_name;

struct network { boost::variant net_id; };

typedef std::vector<network>network_list;

// create the instance for vector

network_list net_list;

for(int i=0; i

ERROR is error: cannot convert ‘boost::variant

’ to ‘unsigned char*’ in assignment

Unless I'm mistaken, to reiterate, *you* need to decide how you want to map a std::vector< std::string > to an unsigned char*; this has nothing to do with Boost.Variant. Once you've figured that out, use either boost::apply_visitor [1] (probably preferred if your actual use case is more elaborate) or boost::get [2] to apply this mapping on your variant value. - Jeff [1] http://www.boost.org/doc/libs/1_49_0/doc/html/boost/apply_visitor.html [2] http://www.boost.org/doc/libs/1_49_0/doc/html/boost/get_id1673528.html
