我在MyTracker.cpp中((CCaptureScreenDlg *)pWnd)->PaintWindow();编译器提示未声明标识符的错误
MyTracker包含
#include "stdafx.h"
#include "MyTracker.h"
#include "CaptureScreenDlg.h"
#include "Resource.h"

CCaptureScreenDlg 包含
#include "Resource.h"
#include "MyEdit.h"
#ifndef MYTRACKER_
#include "MyTracker.h"

// CCaptureScreenDlg 对话框
class CCaptureScreenDlg : public CDialog
