BOOL GetFileSizeAndContent(const string& fileName, long& size, string& strContent)
{


FILE * pFile;
pFile = fopen( fileName.c_str(), "rb");
if (pFile == NULL)
{
return  FALSE;
}
else
{
fseek(pFile, 0, SEEK_END);
size = ftell(pFile);
if (0 == size)
{

                        size = 0;
strContent = "";
fclose(pFile);
return  TRUE;

      

}
strContent.resize(size);
fseek(pFile, 0, SEEK_SET);
fread((char*)&strContent[0], size, 1, pFile);

fclose(pFile);

}
