1、隱藏鼠標

int i = ShowCursor(FALSE);
 for ( i; i >= 0 ;i-- )
 {
  ShowCursor(FALSE);
 }

2、顯示鼠標

 int i = ShowCursor(TRUE);
 for ( i;i<= 0;i++ )
 {
  ShowCursor(TRUE);
 }

3、在Picture Control上顯示圖片

（1）先寫一個類

//.h

#pragma once
using namespace Gdiplus;
#pragma comment(lib, "gdiplus.lib")
// CImagePrieviewStatic
class CImagePreviewStatic : public CStatic
{
 DECLARE_DYNAMIC(CImagePreviewStatic)
public:
     CImagePreviewStatic();
 virtual   ~CImagePreviewStatic();

 virtual BOOL Create();
 virtual void DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct);

 void   SetFilename(LPCTSTR szFilename);

protected:
 WCHAR   m_wsFilename[_MAX_PATH];
 Image   *m_img;
 Graphics  *m_graphics;

 DECLARE_MESSAGE_MAP()
}; 

//.cpp

#include "stdafx.h"
#include "ImagePreviewStatic.h"

// CImagePrieviewStatic
IMPLEMENT_DYNAMIC(CImagePreviewStatic, CStatic)

CImagePreviewStatic::CImagePreviewStatic() : CStatic()
{
 m_img = (Image *) NULL;
 m_graphics = (Graphics *) NULL;
}

CImagePreviewStatic::~CImagePreviewStatic()
{
 //modified by yangjiaxun @ 200701226
 if( m_img )
  delete m_img;
 if( m_graphics )
  delete m_graphics;
}

BOOL CImagePreviewStatic::Create()
{
 if (GetSafeHwnd() != HWND(NULL))
 {
  if (m_img != NULL)
  {
   delete m_img;
   m_img = (Image *) NULL;
  }
  if (m_graphics != NULL)
  {
   delete m_graphics;
   m_graphics = (Graphics *) NULL;
  }

  m_img = new Image(m_wsFilename);
  m_graphics = new Graphics(GetSafeHwnd());
  return TRUE;
 }

 return FALSE;
}

void CImagePreviewStatic::SetFilename(LPCTSTR szFilename)
{
#ifndef _UNICODE
 USES_CONVERSION;
#endif

 ASSERT(szFilename);
 ASSERT(AfxIsValidString(szFilename));

 TRACE("%s\n", szFilename);

#ifndef _UNICODE
 wcscpy(m_wsFilename, A2W(szFilename));
#else
 wcscpy_s(m_wsFilename, szFilename);
#endif

 delete m_img;
 m_img = new Image(m_wsFilename, FALSE);
 Invalidate();
}

void CImagePreviewStatic::DrawItem(LPDRAWITEMSTRUCT /*lpDrawItemStruct*/)
{
 Unit  units;
 CRect rect;

 if (m_img != NULL)
 {
  GetClientRect(&rect);

  RectF destRect(REAL(rect.left), REAL(rect.top), REAL(rect.Width()), REAL(rect.Height())),
   srcRect;
  m_img->GetBounds(&srcRect, &units);
  m_graphics->DrawImage(m_img, destRect, srcRect.X, srcRect.Y, srcRect.Width, srcRect.Height, UnitPixel, NULL);
 }
}

BEGIN_MESSAGE_MAP(CImagePreviewStatic, CStatic)
END_MESSAGE_MAP()

//在另外的.cpp中進行調用

為該Picture Control添加控件變量 CImagePreviewStatic m_adPic;

 m_adPic.Create();
 m_adPic.SetFilename(theApp.g_szDefaultADPic);

4、根據屏幕分辨率改變窗體控件的大小

void xx::StretchControl(UINT uID)
{
 CRect rcControl;
 CRect rcFrame;
 GetDlgItem( IDC_FRAME )->GetWindowRect( rcFrame );
 ScreenToClient( rcFrame );
 GetDlgItem( uID )->GetWindowRect( rcControl );
 ScreenToClient( rcControl );
 long topRate, leftRate, heightRate, widthRate;
 topRate  = rcControl.top      * GetSystemMetrics( SM_CYSCREEN ) / rcFrame.Height();
 leftRate = rcControl.left     * GetSystemMetrics( SM_CXSCREEN ) / rcFrame.Width();
 heightRate = rcControl.Height() * GetSystemMetrics( SM_CYSCREEN ) / rcFrame.Height();
 widthRate = rcControl.Width()  * GetSystemMetrics( SM_CXSCREEN ) / rcFrame.Width();
 GetDlgItem( uID )->MoveWindow( leftRate, topRate, widthRate, heightRate );
 Invalidate();
}

void xx::ShiftControl(UINT uID)
{
 CRect rcControl;
 CRect rcFrame;

 GetDlgItem( IDC_FRAME )->GetWindowRect( rcFrame );
 ScreenToClient( rcFrame );

 GetDlgItem( uID )->GetWindowRect( rcControl );
 ScreenToClient( rcControl );

 long topRate, leftRate;
 topRate  = rcControl.top  * GetSystemMetrics( SM_CYSCREEN ) / rcFrame.Height();
 leftRate = rcControl.left * GetSystemMetrics( SM_CXSCREEN ) / rcFrame.Width();

 GetDlgItem( uID )->MoveWindow( leftRate, topRate, rcControl.Width(), rcControl.Height() );
 Invalidate();
}

5、在listctrl中顯示圖片

（1）addpicture

void xx::addPicture(void)
{
 // TODO: Add your control notification handler code here
 UpdateData(TRUE);

 // validate image directory
 // show hour glass cursor
 BeginWaitCursor();

 // get the names of bitmap files
 if ( !GetImageFileNames() )
 {
  LOG_OUTPUT_WARN(_T("image目錄下沒有圖片。"));
  EndWaitCursor();
  return;
 }
 // draw thumbnail images in list control
 drawPicture();
// set focus and select the first thumbnail in the list control
 //m_ctrList.SetFocus();
 m_ctrList.SetItemState(0, LVIS_SELECTED|LVIS_FOCUSED, LVIS_SELECTED|LVIS_FOCUSED); 

 CRect crt;
 int x = 95;
 int y = 120;
 m_ctrList.GetClientRect(&crt);
 x = (crt.Width() - 20)/3;
 y = crt.Height()/3;
 m_ctrList.SetIconSpacing(x,y);
 
 EndWaitCursor();
}

（2）GetImageFileNames

BOOL xx::GetImageFileNames()
{
 CString strExt;
 CString strName;
 CString strPattern;
 BOOL bRC = TRUE;

 HANDLE     hFind = NULL;
 WIN32_FIND_DATA   FindFileData;
 std::vector<CString> VectorImageNames;

 if ( theApp.g_szPicFilePath[theApp.g_szPicFilePath.GetLength() - 1] == TCHAR(''\\'') ) 
  strPattern.Format( TEXT("%s*.*"), theApp.g_szPicFilePath );
 else
  strPattern.Format( TEXT("%s\\*.*"), theApp.g_szPicFilePath );

 hFind = ::FindFirstFile(strPattern, &FindFileData); // strat search 
 if (hFind == INVALID_HANDLE_VALUE)
 {
  LPVOID  msg;
  ::FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM,
   NULL,
   GetLastError(),
   MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
   (LPTSTR)&msg,
   0,
   NULL);
  //  MessageBox((LPTSTR)msg, CString((LPCSTR)IDS_TITLE), MB_OK|MB_ICONSTOP);
  ::LocalFree(msg);
  return FALSE;
 }

 // filter off the system files and directories
 if (!(FindFileData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)  &&
  !(FindFileData.dwFileAttributes & FILE_ATTRIBUTE_SYSTEM)     &&
  !(FindFileData.dwFileAttributes & FILE_ATTRIBUTE_HIDDEN)     &&
  !(FindFileData.dwFileAttributes & FILE_ATTRIBUTE_TEMPORARY))
 {    
  // test file extension
  strName = FindFileData.cFileName;
  strExt = strName.Right(3);

  if ( strExt.CompareNoCase( TEXT("jpg") ) == 0 )
  {
   // save the image file name
   VectorImageNames.push_back(strName);
  }
 } 

 // loop through to add all of them to our vector 
 while (bRC)
 {
  bRC = ::FindNextFile(hFind, &FindFileData);
  if (bRC)
  {
   // filter off the system files and directories
   if (!(FindFileData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)  &&
    !(FindFileData.dwFileAttributes & FILE_ATTRIBUTE_SYSTEM)     &&
    !(FindFileData.dwFileAttributes & FILE_ATTRIBUTE_HIDDEN)     &&
    !(FindFileData.dwFileAttributes & FILE_ATTRIBUTE_TEMPORARY))
   {
    // test file extension
    strName = FindFileData.cFileName;
    strExt = strName.Right(3);

    if ( strExt.CompareNoCase( TEXT("jpg") ) == 0)
    {
     // save the image file name
     //strName = theApp.g_szPicFilePath + strName;
     VectorImageNames.push_back(strName);
    }
   }
  } 
  else
  {
   DWORD err = ::GetLastError();
   if (err !=  ERROR_NO_MORE_FILES)
   {
    LPVOID msg;
    ::FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM,
     NULL, err,
     MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
     (LPTSTR)&msg, 0, NULL);
    //MessageBox((LPTSTR)msg, CString((LPCSTR)IDS_TITLE), MB_OK|MB_ICONSTOP);
    ::LocalFree(msg);
    ::FindClose(hFind);
    return FALSE;
   }
  }
 } // end of while loop

 // close the search handle
 ::FindClose(hFind);

 // update the names, if any
 if ( !VectorImageNames.empty() )
 {
  // reset the image name vector
  m_VectorImageNames.clear();
  m_VectorImageNames = VectorImageNames;
  return TRUE;
 }

 return FALSE;
}

（3）drawPicture

void xx::drawPicture()
{
 CBitmap*    pImage = NULL;
 HBITMAP  hBmp = NULL;
 POINT  pt;
 CString  strPath;
 int   i;

 // no images
