CArray Setsize

[ckrishnarao2007]

class deque2
{
int m_iIndex; // record number
int m_iOffset; // number of record to insert/delete

};

class deque1
{
public:
std::deque<deque2> m_undoBuff;
std::deque<deque2>::iterator m_undoPtr;

deque1()
{
m_undoPtr = m_undoBuff.begin();
}

~deque1()
{
m_undoPtr = m_undoBuff.begin();
}

};

void CkkkDlg::OnBnClickedOk()
{

CArray<deque1,deque1&> carray1;


carray1.SetSize(1);
carray1[0].m_undoPtr=carray1[0].m_undoBuff.begin(); -> (1)


carray1.SetSize(3);
carray1[0].m_undoPtr=carray1[0].m_undoBuff.begin();-> (2)

}

this code is running fine at (1) where as it is giving error at (2)
Thanks in advance, please tell me the error in the code

Is CArray running your deque1 constructors ??

I mean, were this a vector, the array is empty so subscript 0 is invalid until you put an object in the container.

BTW: Why CArray and not vector<> ???

This code is building fine in VC++2003 where as it is giving runtime error
"Unhandled exception at 0x00413ff0 in kkk.exe: 0xC0000005: Access violation reading location 0xfeeefef2."
