That wont quite work. The mapped type is a vector of pairs, not just a pair by itself. You'd need:
Code:
configFileDataVector.insert(std::make_pair("fdsf", std::vector(1, std::make_pair("Peter Q.", "5328"))));
However, I'd suggest simply doing this instead:
Code:
configFileDataVector["fdsf"].push_back(std::make_pair("Peter Q.", "5328"));
Note that this assumes that the key value doesn't currently map to a non-empty vector, or that you actually intend to insert multiple items into the vector in this manner.
