Question

MFC视图和文档的传递问题

用单文档拆分后，主类用的CView,两个拆分窗口的类是CView和CStrollView，我在第一个拆分的窗口内调用文档总是提示错误。 CEg001Doc* pDoc = GetDocument();然后提示错误：error C2440: 'initializing' : cannot convert from 'class CDocument *' to 'class CEg001Doc *'
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

Answer 1

CEg001Doc* pDoc = (CEg001Doc* )GetDocument();这样就可以了。
