QT编写DLL 用 QTWinmigrate及例子，超级值得下载

Qt/MFC Migration Framework v2.8 The Qt/MFC Migration Framework tool assists in the migration of existing Win32 or MFC applications to the Qt toolkit. The project provides a set of classes that allow using Qt and MFC/Win32 windows in the same application. User interface elements developed with Qt can be embedded into an existing MFC or Win32 based user interface, and existing custom controls developed with MFC or Win32 can be integrated into Qt widgets. Notes: When building this component as a library ("configure.bat -library"), the default configuration includes MFC support. That is, the MFC SDK must be present, otherwise compilation will fail. To avoid this dependency (e.g. for usage with Visual Studio Express editions, which do not include MFC), edit the src/qtwinmigrate.pri file as explained in its comments before building this component.
