Re: i need Slideshow control

Here is a very simple one I wrote in 10 minutes.
It doesn't do scaling, you want to scale the images so that they are all
the same size you will have to Draw the Image yourself.

#pragma once

// CSlideShowCtrl

class CSlideShowCtrl : public CStatic
{
DECLARE_DYNAMIC(CSlideShowCtrl)

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

  void Start(CString Dir);
  void Stop();
protected:
  afx_msg void OnTimer(UINT nIDEvent);
DECLARE_MESSAGE_MAP()
private:
  CFileFind m_Finder;
  BOOL m_Ret;
  CString m_Dir;
};

// SlideShowCtrl.cpp : implementation file
//

#include "stdafx.h"
#include "SlideShowCtrl.h"
#include <atlimage.h>

// CSlideShowCtrl

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

CSlideShowCtrl::~CSlideShowCtrl()
{
}

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

// CSlideShowCtrl message handlers
void CSlideShowCtrl::Start(CString Dir)
{
  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)
        {
           SetBitmap(Image.Detach());
           break;
        }
     }
  }
  SetTimer(100,1000,NULL);
}

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

void CSlideShowCtrl::OnTimer(UINT nIDEvent)
{
  if (nIDEvent == 100)
  {
     if (!m_Ret)
     {
        m_Ret = m_Finder.FindFile(m_Dir+"\\*.*");
     }

     while (m_Ret)
     {
        m_Ret = m_Finder.FindNextFile();
        if (!m_Finder.IsDirectory())
        {
           CImage Image;
           if (Image.Load(m_Finder.GetFilePath()) == S_OK)
           {
              SetBitmap(Image.Detach());
              break;
           }
        }
     }
  }

  CStatic::OnTimer(nIDEvent);
}
