A_LaxmanGetClientRect(&rect);
In this scenario we pass object as Reference

false... we pass the object by pointer.

in this case, the prototype of the function is not GetClientRect(RECT&); but GetClientRect(RECT*);

never... this function simply doesn't exist. GetClientRect gets a pointer (or a const ptr) of RECT...

The CWnd::GetClientRect function actually requires an argument of type “pointer to RECT” -- RECT *, or LPRECT.

Nevertheless, this function can be used in more contexts:

RECT rect1;
GetClientRect(&rect1); // pass LPRECT
<br>
//
CRect rect2;
GetClientRect(&rect2); // works because CRect is public-derived from RECT,
                       // therefore an implicit conversion 
                       // from CRect* to LPRECT is available
//
CRect rect3;
GetClientRect(rect3); // works because CRect provides 
                      // a conversion operator to LPRECT

The design of CRect class allow you to use it with Windows functions that actually require LPRECT.

Thanks for the detailed reply.

when I have checked the MFC defintion of CRect, I could find that

the operators are defined as follows

// convert between CRect and LPRECT/LPCRECT (no need for &)
operator LPRECT() throw();
operator LPCRECT() const throw();

see GetClientRect() in MSDN
void GetClientRect( LPRECT lpRect ) const;
Actual argument needed is of type LPRECT

If you give GetClientRect(rect) or GetClientRect(&rect)both returns same because CRect has got .operator LPRECT() which automatically get invoked if you pass rect. But i tell u that &rect is more correct.

set the "Send" button as the default button (with CWindow::SetDefId()) so that an Enter key press will press this button.

As toxcct said, handle the EN_CHANGE notification. In addition or as an alternative, you can handle WM_CHAR in your CEdit-derived class.
There you can 'eat' characters before CEdit even gets to see them.

"We trained hard, but it seemed that every time we were beginning to form up into teams we would be reorganised. I was to learn later in life that we tend to meet any new situation by reorganising: and a wonderful method it can be for creating the illusion of progress, while producing confusion, inefficiency and demoralisation."

Here is another notification event EN_UPDATE that is fired before updating the Edit control.

This notification message is sent after the control has formatted the text, but before it displays the text.
