The issue is that you are trying to copy data from a multi-dimensional array using a single dimension pointer; and given the structure of your original array you have no other choice.

struct dataArray
{
    wchar_t item[ MAX_NAME_SIZE ];
} names[COMMON_ARRAY_SIZE];
// names is an array of structures
Set_Pointer(names);


void Set_Pointer(dataArray* new_pointer)
{
    dataArray* mp_local_pointer;
    mp_local_pointer = new_pointer;
    wcscpy_s(one, MAX_NAME_SIZE, dataArray[0].item); // OK
    wcscpy_s(two, MAX_NAME_SIZE, dataArray[1].item); // OK
    ...
}

Does that help narrow the field?
