it is. sometimes, the operating system can clean the memory you forgot the free, but sometimes, it won't... thus the memory leak.

Unaltered new operators will never leak memory after the application exits. Maybe if you've overriden a new operator to allocate shared memory or something similar.

Without deleting the alloacated memory, my application exits.
It is a memory leak. Every new should be followed by a delete and every new [] should be followed by delete [].

Technically, it's a memory leak. Practically, it isn't. All memory allocated on the heap in a process is automatically returned when the process is terminated.
A "real" memory leak's characteristics is one that grows with time, which will eventually starve the system of free memory. Assuming of course that the memory allocated isn't used after a certain point. If the app really uses and needs the memory, it doesn't qualify as a memory leak. It could mean that the application is poorly designed.
If you for instance make one allocation in the application, and you don't free it, it's not a memory leak. If you continously make memory allocations in the application, without freeing them when you no longer require the memory, then you've got yourself a very real memory leak.

Hi all,
Can u please tell me how to update an edit-box field present in a model-dialog from another class
I have used
CUsatDlg *dlg= new CUsatDlg;
HWND hdlg =dlg->m_hWnd;
SetDlgItemText(hdlg,IDC_SERIALNO,"Serial");
UpdateWindow(hdlg);
Where CUsatDlg is mu dialog box class ,and IDC_SERIALNO is my edit box field
But the edit-box is not displaying the text

You need to pass a pointer of the class (where the edit box is contained) to another class. Using that pointer you can access the variables in another class.

Here is a sample code. You access the function of class B from class A. On similar lines you can also use the variables etc.
#include <iostream>
using namespace std;
class B
{
public:
B()
{
cout<<"Constructor of B\n";
}
void Display()
{
cout<<"In Function Display of B\n";
}
};
class A
{
public:
B b;
A()
{
cout<<"Constructor of A\n";
}
void CallBClassFn()
{
b.Display();
}
};
int _tmain(int argc, _TCHAR* argv[])
{
A a;
a.CallBClassFn ();
return 0;
}
I hope this helps in solving out your problem...

if your main class is Main and another class in Local you can use this code on Local class
<br />
CMain *m_Main=(CMain*)GetParent();<br />
m_Main->functions or variables<br />

Simply post a message to the window (e.g., dialog) that owns the edit control.

you need the actual Window Handle of displayed window.. this willnot help..
either have a pointer to that class. or make some global variable!

Hi Friends
MessageBox is not displayed in ExitInstance function in MFC Dialogbased Application ?

this is because WM_QUIT message lies in the message queue.
try the below code. It just remove the WM_QUIT message.
MSG stMsg= {0};
while( ::GetMessage( &stMsg,0,0,0))
{
}
AfxMessageBox( L"hi" );
