Hi, Neerav.
I think I answered the wrong mail.

--> 0x0018, 0x5212 is not a binary element, but as "DS" -Decimal String-
To get the values, you must use something like :
DataEntry *e_0018_5212 = f->GetDataEntry(0x0018, 0x5212);
std::vector <double> valueVector;
bool res = e_0018_5212->GetDSValue(valueVector);
if (!res)
   std::cout << "Sorry, you cannot use GetDSValue on non DS DataElement" ...
