该代码段展示了如何在VC中通过图标句柄（HICON）保存为ICO文件。首先，创建PICTDESC结构并初始化，接着利用OleCreatePictureIndirect创建IPicture接口。然后，创建一个内存流（LPSTREAM），并通过IPicture的SaveAsFile方法将图标保存到流中。最后，读取流的内容并写入目标文件完成保存。

void CMyDlg::SaveIcon(HICON hIconToSave, LPCTSTR sIconFileName)
{
      if(hIconToSave==NULL || sIconFileName==NULL)
        return;
      PICTDESC picdesc;
      picdesc.cbSizeofstruct = sizeof(PICTDESC);
       picdesc.picType = PICTYPE_ICON ;
       picdesc.icon.hicon = hIconToSave;
      IPicture* pPicture=NULL;
      OleCreatePictureIndirect(&picdesc, IID_IPicture, TRUE,(VOID**)&pPicture);
       LPSTREAM pStream;
       CreateStreamOnHGlobal(NULL,TRUE,&pStream);
     LONG size;
     HRESULT hr=pPicture->SaveAsFile(pStream,TRUE,&size);
      char pathbuf[1024];
      strcpy(pathbuf,sIconFileName);
      CFile iconfile;
     iconfile.Open(pathbuf, CFile::modeCreate|CFile::modeWrite);
      LARGE_INTEGER li;
      li.HighPart =0;
      li.LowPart =0;
     ULARGE_INTEGER ulnewpos;
     pStream->Seek( li,STREAM_SEEK_SET,&ulnewpos);
     ULONG uReadCount = 1;
      while(uReadCount>0)
   {

       pStream->Read(pathbuf,sizeof(pathbuf),&uReadCount);
        if(uReadCount>0)
         iconfile.Write(pathbuf,uReadCount);
     }
      pStream->Release();
       iconfile.Close();
}
