Hello.

I am working with source which is not for MFC. It seems to be coded
for their own class library.
When I got this code, source file didn't included "stdAfx.h" and
include some other header file.
So it spawns lots of error message when I compile with MFC.
One message is on function overloading
code is as below.

--
BOOL CEdit::Create(HINSTANCE hInstance, DWORD dwStyle, const RECT&
rect, CWnd* pParentWnd, UINT nID)
{
CWnd* pWnd = this;
return pWnd->Create(_T("EDIT"), NULL, dwStyle, rect,
pParentWnd, hInstance, (HMENU)nID, NULL);
}
--

in .h file

--
class CEdit
: public CWnd
{
DECLARE_RUNTIMECLASS(CEdit)

// Constructors
public:
CEdit();
virtual ~CEdit();

BOOL Create(HINSTANCE hInstance, DWORD dwStyle, const RECT&
rect, CWnd* pParentWnd, UINT nID);
....
....
--

error message is

--
error C2511: 'Create' : overloaded member function 'int (struct
HINSTANCE__ *,unsigned long,const struct tagRECT &,class CWnd
*,unsigned int)' not found in 'CEdit'
c:\program files\microsoft visual
studio\vc98\mfc\include\afxwin.h(2974) : see declaration of 'CEdit'
--

parameters of declaration and definition is same and I wonder why I
met this problem.
parameters of Create() function in function body is next problem and I
met error in start of function.

Please help me solve this problem.
Thanks.

MFC has always had its own class named "CEdit". You're going to have to
rename your class or put it in a namespace. Renaming is the better choice
by far, because it would be confusing to have two classes named CEdit in an
MFC program. It just wouldn't occur to an MFC user that "CEdit" means
anything but MFC's CEdit.

MFC has a class named "CEdit" so you cannot make a class of your own with
the same name.

Does their class library define a class called "CEdit"? If so, consider it incompatible
with MFC.

So what header file are you including, and if it is stdafx.h, is it the stock one?

There is no CEdit method in MFC that looks like this. The only documented CEdit::Create
is

virtual BOOL CEdit::Create(DWORD dwStyle, const RECT & rect, CWnd * pParentWnd, UINT nID)

so yes, the call is inconsistent with this, because it has an HINSTANCE parameter.

The above line is silly
****

>pParentWnd, hInstance, (HMENU)nID, NULL);
****
The correct call is
return CWnd::Create(_T("EDIT"), NULL, dwStyle, rect, pParentWnd, id);
and there is no method of CWnd that takes an HINSTANCE, since there is no useful purpose
served by this parameter.

Which .h file? I'm sure it has a file name, and it isn't called ".h"

Do you see an instance parameter here?

This error message is absolutely correct, and is telling you exactly what you have done
wrong; you have an incorrect Create call, because there is no method of CEdit that takes
an HINSTANCE as its first parameter. Remove the HINSTANCE parameter!
