tgui::ComboBox::getSelectedItem() should be used.

You might use this tool to check if all the functions are exported to your DLLs and that they have access to them.

I used to get some of these "procedure entry point could not be located" errors in VS12 myself with SFML. And every time the reason was either incorrect build or incorrect linking.

Also, this thread here might contain some info you are looking for.
