If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you

I know that you can use automation to create doc file but I don't know if the format is the same as a docx file.

How to resolve this error yet? Do i have to write another operator= for DeptDetails*. Can you let me know the code so I don't make mistake again.

One more query I have:
I wanted to store deptNo (int) as key & DeptDetails as value in a Map. I looked at CMap but couldn't find any method to iterate the map contents, hence selected CMapStringToPtr seemed to be best suited to store deptNo in the form of CString. Is this decision correct or should I approach some other class of CMap.

class DeptDetails : public CObject
{
	DECLARE_SERIAL(DeptDetails);

public:
	DeptDetails(void);
	DeptDetails(int dno, CString name, float vat);
	DeptDetails(const DeptDetails &d);	// Copy Constructor
	// = Assignment operator
	DeptDetails& operator=(const DeptDetails &d);

IMPLEMENT_SERIAL(DeptDetails, CObject, 1);

DeptDetails::DeptDetails(void)
: deptNo(0)
, deptName(_T(""))
, vat(0)
{
}

DeptDetails::DeptDetails(int dno, CString name, float vat) {
	deptNo = dno;
	deptName = name;
	this->vat = vat;
}

// Copy Constructor
DeptDetails::DeptDetails(const DeptDetails &d) {
	deptNo = d.deptNo;
	deptName = d.deptName;
	vat = d.vat;

// Assignment operator
DeptDetails& DeptDetails::operator=(const DeptDetails &d) {

Have I implemented the CArchive correctly in Write & Read Departments. Please check out that.
