1.標頭檔案

#include "../../controls.extend/FileHelper.h"
#include <GdiPlus.h>
#pragma comment(lib,"gdiplus")

2.建立控制元件

SImageWnd* m_pImage_Goods;

3.顯示圖片

    CFileDialogEx openDlg(TRUE, _T("jpg"), 0, 6, _T("jpg files(*.jpg)\0*.jpg\0All files (*.*)\0*.*\0\0"));
    if (openDlg.DoModal() == IDOK)
    {
        SStringT strFileName = openDlg.m_szFileName;

        CRect rc = m_pImage_Goods->GetClientRect();
        
        IRenderTarget* pRT = m_pImage_Goods->GetRenderTarget(&rc, OLEDC_PAINTBKGND);

        HDC hdc = pRT->GetDC();

        Gdiplus::Graphics *pGraphics = new Gdiplus::Graphics(hdc);

        Gdiplus::Bitmap *pBitmap = Gdiplus::Bitmap::FromFile(strFileName);

        pGraphics->DrawImage(pBitmap, rc.left, rc.top, rc.Width(), rc.Height());

        delete pBitmap;

        delete pGraphics;

        pRT->ReleaseDC(hdc);

        m_pImage_Goods->ReleaseRenderTarget(pRT);
    }
