(m_Pic.LoadPictureData(pBuffer, nSize));//接作调用函数读pBuffer的jpg数据准备显示showimage();//显示图片void Caccess_test_1Dlg::showimage()//显示图片{    CRect rect;    GetDlgItem(IDC_STATIC_pic)->GetWindowRect(&rect);//将矩形窗口选中到picture空间里    //ScreenToClient(&rect);    CWnd *pWnd = GetDlgItem(IDC_STATIC_pic);//获得Picture窗口句柄    pWnd->GetClientRect(&rect);//获得Picture窗口矩形区域    CDC *pDC = pWnd->GetDC();    //m_image.Draw(pDC->m_hDC, rect, Gdiplus::InterpolationModeNearestNeighbor);    m_Pic.Show(pDC->m_hDC, rect);    ReleaseDC(pDC);    return;}

出错：

 

将：

m_Pic.Show(pDC->m_hDC, rect);

改为：

m_Pic.Show(pDC, rect);

 

success！
