I have a void pointer to an NTL Array and VectorMap, how do I receive the elements through the key?
The code looks like this:

	typedef VectorMap<String, String> ntlMap;
	typedef Array<String> ntlArray;
	
	void* ptra;
	void* ptrm;
	
	ptra = new ntlArray;
	ptrm = new ntlMap;
	
	for(int i = 0; i < ((ntlMap*)ptrm)->GetCount(); i++)
		((ntlArray*)ptra)->???? = ((ntlMap*)ptrm)->????;

Or you can do this:

ntlMap& map = *(ntlMap *)ptrm;
ntlArray& array = *(ntlArray *)ptra;
for(int i = 0; i < map.GetCount(); i++)
     array[i] = map[i];

BTW, I only hope that you are doing something really special Smile

Using 'new' should be reserved only for really desperate cases Smile

Only be aware that U++ will teach you something little bit different from "classic" approach...
