you can always use a std::ostringstream, like

#include <sstream>
#include <string>

std::string toString( void* p )
{
    std::ostringstream stream;
    stream << p;
    return stream.str();
}

note: if it is a function pointer then it's not formally convertible to void*, and then you have to adjust signature of function above to take your pointer type.

you may also have to add const etc.

instead of writing such functions yourself you can use boost::lexical_cast, from the Boost library.

Cheers & hth.,

long* number;//=0x6859510364;
TCHAR str[20];
_ltot_s(*number, str, 16);
