Question

CEdit &MyEdit=GetEditCtrl();这条语句为啥在CView基类的派生类下的函数中会出错？

Answer 1

显示GetEditCtrl()没声明.
类不同,记得CEDIT是CWND类。

Answer 2

只能用在以CEditView为基类的类中

Answer 3

不知道

追问

void CStuGradeView（CView基类）::OnShow()
{
// TODO: Add your command handler code here
char buff[1000];
memset(buff,0,sizeof(buff));
top->display(top,buff,4);
CEdit &MyEdit=GetEditCtrl();
MyEdit.SetWindowText(buff);

}

error C2065: 'GetEditCtrl' : undeclared identifier
error C2440: 'initializing' : cannot convert from 'int' to 'class CEdit &'
