Here you use execution, before you had ie2 as a pointer. You should
make sure that the examples you give are actually compiling, otherwise
it is really hard to figure out what the actual problem is.

Looks like you want to access the string of the titlevalue. That is a
std::string, so you can't just cast that to a char*; you might want to
access the content of the stringt with titlevalue.c_str(), which
returns the nul-terminated string you seem to look for (
