Re: i need Slideshow control

Here is another version. This version resizes the images to fit the
static control.
Place static control on your dialog box, give it an ID, attach a variable
to it, change the variable type from CStatic to CSlideShowCtrl

#pragma once

#include <atlimage.h>

// CSlideShowCtrl

class CSlideShowCtrl : public CStatic
{
  DECLARE_DYNAMIC(CSlideShowCtrl)

public:
  CSlideShowCtrl();
  virtual ~CSlideShowCtrl();

  void Start(CString Dir,UINT Interval);
  void Stop();
protected:
  afx_msg void OnTimer(UINT nIDEvent);
  DECLARE_MESSAGE_MAP()
private:
  CFileFind m_Finder;
  BOOL m_Ret;
  CString m_Dir;
  CImage m_CurImage;
  afx_msg void OnPaint();
  afx_msg BOOL OnEraseBkgnd(CDC* pDC);
};

// SlideShowCtrl.cpp : implementation file
//

#include "stdafx.h"
#include "SlideShowCtrl.h"

// CSlideShowCtrl

IMPLEMENT_DYNAMIC(CSlideShowCtrl, CStatic)
CSlideShowCtrl::CSlideShowCtrl()
{
}

CSlideShowCtrl::~CSlideShowCtrl()
{
}

BEGIN_MESSAGE_MAP(CSlideShowCtrl, CStatic)
  ON_WM_TIMER()
  ON_WM_PAINT()
  ON_WM_ERASEBKGND()
END_MESSAGE_MAP()

// CSlideShowCtrl message handlers
void CSlideShowCtrl::Start(CString Dir,UINT Interval)
{
  m_Dir = Dir;
  m_Ret = m_Finder.FindFile(Dir+"\\*.*");
  while (m_Ret)
  {
     m_Ret = m_Finder.FindNextFile();
     if (!m_Finder.IsDirectory())
     {
        CImage Image;
        if (Image.Load(m_Finder.GetFilePath()) == S_OK)
        {
           m_CurImage.Destroy();
           m_CurImage.Attach(Image.Detach());
           Invalidate();
           UpdateWindow();
           break;
        }
     }
  }
  SetTimer(100,Interval,NULL);
}

void CSlideShowCtrl::Stop()
{
  KillTimer(100);
}

void CSlideShowCtrl::OnTimer(UINT nIDEvent)
{
  if (nIDEvent == 100)

              Invalidate();
              UpdateWindow();
              break;
           }
        }
     }
  }

  CStatic::OnTimer(nIDEvent);
}

void CSlideShowCtrl::OnPaint()
{
  CPaintDC dc(this); // device context for painting

  CRect Rect;
  GetClientRect(&Rect);
  double Ratio = 1.0;
  if (m_CurImage.GetWidth() > Rect.Width())
  {
     Ratio = (double)Rect.Width() / (double)m_CurImage.GetWidth();

  }
  int X = (int)(Rect.Width() - (m_CurImage.GetWidth()*Ratio)) / 2;
  int Y = (int)(Rect.Height() - (m_CurImage.GetHeight()*Ratio)) / 2;

m_CurImage.Draw(dc.GetSafeHdc(),X,Y,m_CurImage.GetWidth()*Ratio,m_CurImage.GetHeight()*Ratio);
}

{
  CRect Rect;
  GetClientRect(&Rect);
  pDC->FillSolidRect(Rect,RGB(127,127,127));

  return TRUE;
