Hi!
Do you use same compiler in your QtCreator project(VS 2010)?
When you create C++ dll in output you get *.dll and *.lib files. In this case you can do like "doc":http://qt-project.org/doc/qtcreator-2.7/creator-project-qmake-libraries.html but if you want load library in runtime and for some reasons you don't have *lib and header files you can use "QLibrary":http://qt-project.org/doc/qt-5.0/qtcore/qlibrary.html
