need help.

I need help,I have been reading a book called game programming all in one,by Bruno Migeul Teixeira de Sousa.I am having a problem with getting the code for the reusable to work.I get errors.I fixed as many of them as i could,but I still have 10 left to deal with.if anyone could help me i would really appericate it.Here are the error's that i get.Below that is the code.As far as the Mirus.h error i tried to add that file,and i still get error's. the error's I have been getting. ----------------------------------------------------------------- 03 Main.cpp(5): fatal error C1083: Cannot open include file: 'Mirus.h': No such file or directory mrwindow.cpp(18): error C2143: syntax error : missing ';' before 'mrWindow::Create' mrwindow.cpp(18): error C2501: 'mrError32' : missing storage-class or type specifiers mrwindow.cpp(41): error C2065: 'mrErrorRegisterClass' : undeclared identifier mrwindow.cpp(50): error C2065: 'mrNoError' : undeclared identifier mrwindow.cpp(65): warning C4311: 'type cast' : pointer truncation from 'LPVOID' to 'long' mrwindow.cpp(69): warning C4312: 'type cast' : conversion from 'LONG' to 'mrWindow *' of greater size mrWindow.h(25): error C2146: syntax error : missing ';' before identifier 'Create' mrWindow.h(25): error C2501: 'mrWindow::mrError32' : missing storage-class or type specifiers mrWindow.h(28): warning C4183: 'Create': missing return type; assumed to be a member function returning 'int' ----------------------------------------------------------------- here are the header files.
