f your application uses MFC in a shared DLL, and your application is in a language other than the operating system s current language, you will need to copy the corresponding localized resources MFC42XXX.DLL from the Microsoft Visual C++ CD-Rom onto the system or system32 directory, and rename it to be MFCLOC.DLL. ("XXX" stands for the language abbreviation. For example, MFC42DEU.DLL contains resources translated to German.) If you don t do this, some of the UI elements of your application will remain in the language of the operating system.

C++讀取Excel AppWizard uses "TODO:" to indicate parts of the source code you should add to or customize. If your application uses MFC in a shared DLL, and your application is in a language other than the operating system s current language, you will need to copy the corresponding localized resources MFC42XXX.DLL from the Microsoft Visual C++ CD-Rom onto the system or system32 directory, and rename it to be MFCLOC.DLL.
