string temp_file;

1. Breakpoint there. 2. Observe the involved variables. 3. Is something smelly? That's the thief. Goto 6. 4. Step. Exception thrown? If so, you should have smelled it in 3. 5. Goto 2. 6. End. It's likely the assignment (will call string::assign et al under the hood, to which you have the sources and should therefore find the error source) that throws because my_dir is in fact NULL, not "C:\\Projects".
