user104780: I canceled one transaction that was in the memory pool, now I would like to make sure that this transaction will not be sent anymore sending all BTC amount of the original address of this transaction to another address, but when I go to send BTC in Bitcoin Core, I can't choose one specific address to send the amount. So what Can I do to "empty" the bitcoins of this address using Bitcoin Core?

user38618: If you run Core with the command line flag -zapwallettxes it will forget transactions in its mempool.
