char *pStr = text.GetBuffer(text.GetLength()); //取得str对象的原始字符串int nBufferSize = MultiByteToWideChar(CP_UTF8, 0, pStr, -1, NULL, 0); //取得所需缓存的多少wchar_t *pBuffer = (wchar_t*)malloc(nBufferSize * sizeof(wchar_t));//申请缓存空间MultiByteToWideChar(CP_UTF8, 0, pStr, -1 , pBuffer, nBufferSize*sizeof(wchar_t));//转码//MessageBoxW(NULL, pBuffer, L"Text", MB_OK); //显示httpsource=httpsource+pBuffer+"\r\n";free(pBuffer); //释放缓存//MessageBox(text);   }   pHTTPFile->Close();   delete   pHTTPFile;   }
