我是个新手
void CMainFrame::OnStudentInfo()
{
// TODO: Add your command handler code here
m_pStudentInfo = new CChildFrame();
CCreateContext Context;
Context.m_pNewViewClass = RUNTIME_CLASS(CStudentInfo);
if(!m_pStudentInfo->LoadFrame(IDR_MAINFRAME,WS_OVERLAPPEDWINDOW | FWS_PREFIXTITLE,this,&Context))
return;
m_pStudentInfo->InitialUpdateFrame(NULL,TRUE);
//禁止再次开打此窗口
m_bItemStudentInfo = FALSE;
}
上面的菜单响应函数
其中 类CStudentInfo 的定义如下 继承了CObject类
class CStudentInfo : public CObject
{
public:
CStudentInfo();
virtual ~CStudentInfo();};
编译时错误如下:
E:\VC6.0\高校教务管理系统学生端\MainFrm.cpp(278) : error C2039: 'classCStudentInfo' : is not a member of 'CStudentInfo'

这个头文件已经加了哈
