我試圖讓Windows形成，這是Form1.h：轉換的Win32控制檯應用程序Windows窗體應用程序

和頭文件我已經添加了頭文件student.h並寫班級學生它： student.h：
#include<iostream>
#include<string>
using namespace std;
class student
{
int id;
int grade1,grade2,grade3;
public:
student()
{
}
void setStudent(int a,int b,int c,int d)
{
id=a;
grade1=b;
grade2=c;
grade3=d;
}
int maxGrade()
{
int max=grade1;
if(grade2>max)
max=grade2;
if(grade3>max)
{
max=grade3;
}
return max;
}
};
但是，編譯器給我的錯誤：
錯誤3錯誤C2662：' student :: maxGrade'：無法將'this'指針從'student'轉換爲'student'&'
錯誤2錯誤C2662：'student :: setStudent'：無法將'this'指針從'student'轉換爲'student &「
錯誤1錯誤C4368：無法定義的」作爲管理的一員‘formApp :: Form1的’：混合型，不支持
請你能告訴我正確的方式來增加學生類到Windows窗體應用程序並使用它。
