Ask how to define a structure in MFC, ask to select one part of the structure, and display another part
I define the structure like this:
struct CStruct
{
CString Name;
CString XueFen;
};

BOOL CMy2Dlg :: OnInitDialog ()
{
CStruct str [4] = {"Advanced Mathematics", "6", "data", "6", "java", "7", "English",
"4"};
int n;
for (int i = 0; i <= 4; i ++)
{
n = m_select.AddString (str [i] .Name);
m_select.SetItemData (n, i); // Realistic drop-down list
}
m_select.SetCurSel (0);
return TRUE; // return TRUE unless you set the focus to a control
}

The definition is wrong here, please advise!
There is also how to select a subject in the drop-down menu to display the credits of this subject
If "JAVA" is selected, the credits will be displayed in the edit box next to "6"

Please advise

CStruct str [4] = {{"Advanced Mathematics", "6"}, {"data", "6"}, {"java", "7"}, {"English", "4"}};
Should be defined like this

No, I still report an error!

for (int i = 0; i <= 4; i ++) // Change to: for (int i = 0; i <4; i ++)
{
n = m_select.AddString (str [i] .Name);
m_select.SetItemData (n, i); // Realistic drop-down list
}

Ibid. The concept of arrays is not very clear. Think about it carefully. 0 1 2 3 is 4. Where did 4 come from !!!!!!!!!!!!

CStruct str[4]={"Advanced Mathematics","6","data","6","java","7","English","4"};
