    Creating a CMyEdit class with CEdit

    Hi,

    I've created a CMyEdit class using CEdit as the base class, and I've defined my own OnSetFocus function. But Everytime I create an instance of CMyEdit it gives me an error
    Code:
    error C2065: 'CMyEdit' : undeclared identifier
    I haven't done this before and really don't know whether I've done all I was supposed to do. Could I have some assistance, please.
    Everything is relative...

    You have included the header for MyEdit (MyEdit.h) in the file you want to declare the edit in?




    may need a pragma once or conditional compilation

    ie C style conditional compilation.....

    //include the file only once
    #ifndef MY_EDIT_CLASS //if not defined
    #define MY_EDIT_CLASS //define it
    #include "MyEdit.h"
    #endif //close the condition

    what novacain said, and if you are using Microsoft Visual C++ and you have more than one .cpp files it can be a bit messed up, not too long ago i had problems with it.

    Just hit 'Rebuild All' or 'Clean'.

    If still problems, delete the contents of your Debug folder and use rebuild all.

    I have added the header file, but I can't properly overrider a base class function.

    Here's the whole class definition:
    Code:
    #include "stdafx.h"
    #include "Initial GUI.h"
    #include "MyEdit.h"
    
    #ifdef _DEBUG
    #define new DEBUG_NEW
    #undef THIS_FILE
    static char THIS_FILE[] = __FILE__;
    #endif
    
    /////////////////////////////////////////////////////////////////////////////
    // CMyEdit
    
    CMyEdit::CMyEdit()
    {
    	void CMyEdit::OnSetfocus(CWnd* pOldWnd);  //CWnd* pOldWnd
    }
    
    CMyEdit::~CMyEdit()
    {
    }
    
    
    BEGIN_MESSAGE_MAP(CMyEdit, CEdit)
    	//{{AFX_MSG_MAP(CMyEdit)
    	ON_CONTROL_REFLECT(EN_SETFOCUS, OnSetfocus)
    	//}}AFX_MSG_MAP
    END_MESSAGE_MAP()
    
    /////////////////////////////////////////////////////////////////////////////
    // CMyEdit message handlers
    
    void CMyEdit::OnSetfocus(CWnd* pOldWnd) //CWnd* pOldWnd
    {
    	CString lstr, estr, str;
     
    	this->selectedEditControl = 1;
    
    	CListBox* pGetList = (CListBox*)this->GetParent()->GetDlgItem(IDC_LIST1);
    
    	pGetList->GetText((pGetList->GetCurSel()), lstr);
    		 
    	this->SetWindowText(lstr);
    	
    }
    I get this error
    Code:
    error C2244: 'CMyEdit::OnSetfocus' : unable to resolve function overload
    h:\gui\gui v1\myedit.cpp(37) : error C2511: 'OnSetfocus' : overloaded member function 'void (class CWnd *)' not found in 'CMyEdit'

    try....

    in prototype (header)

    afx_msg void OnSetfocus();

    or

    afx_msg void OnSetfocus(CWnd *pOldWnd);
