怎么在对话框上加载图片

Question

我想根据图片的路径来加载图片显示到对话框上，（路径是从XML里读出来的），然后根据XML里的一些配置项循环创建复选框。请问该怎么做呢读XML没有问题

Answer 1

LoadImage(CString pathName,CDC* pDC)
{
IStream* pStream;
IPicture* pPicture;
CFile file;    if(!file.Open(pathName,CFile::modeRead))
return; DWORD m_nFileLen;
m_nFileLen=file.GetLength(); HGLOBAL hMem=::GlobalAlloc(GMEM_MOVEABLE,m_nFileLen);
LPVOID lpBuf=::GlobalLock(hMem);    if(file.ReadHuge(lpBuf,m_nFileLen)!=m_nFileLen)
return;

file.Close();
::GlobalUnlock( hMem ); if(CreateStreamOnHGlobal(hMem,TRUE,&pStream)!=S_OK)
return;
if(OleLoadPicture(pStream,m_nFileLen,TRUE,IID_IPicture,(LPVOID*)&pPicture)!=S_OK)
return;

long nWidth,nHeight; 
pPicture->get_Width( &nWidth ); 
pPicture->get_Height( &nHeight );

CSize sz( nWidth, nHeight );
pDC->HIMETRICtoDP( &sz );
pPicture->Render(pDC->m_hDC,0,0,sz.cx,sz.cy,0,nHeight,nWidth,-nHeight,NULL); pPicture->Release();
pStream->Release();
}
传入路径和dc
