I actually don't need them. I'm supposed to put 60466176 entries into a database and check db's size. I think, if I put 1 entry at a time into the db, the function won't run out of memory. However I felt that 8 GB should have sufficed VirtualAlloc() failed: [0x00000008] Not enough storage is available to process this command.

Can someone please enhance this function. This function generates all possible 5 character combinations.
