So i am a total noob in using bitcoin qt and im am currently using bitcon qt v.0.8.2
Why are you using 0.8.2? The most current release is 0.8.6
Are you sure you have the correct (real) Bitcoin-Qt? Where did you get it from?
someone just send me some amount of btc to my wallet address and it's been almost 24 hours since then the bitcoin never arrived to my wallet.There is confirmation last night up to 65 and now there isnt any according to blockchain.
Blockchain currently indicates a single transaction sent to that address on 2014-02-14 at 09:07:16 GMT. That transaction now has 421 confirmations.
My wallet is up to date since there is a green mark in the bottom right corner and 14 active connection to the network right now.
here's what shows in the blockchain
https://blockchain.info/address/19tK2WMKoxZ8GNRLBVRK3yecb79TQVJTKican someone please help me ?? i tried -rescan twice but didn't work and i also tried opening my wallet since the rescan untill now in case if there will be a rebroadcasting but still never arrived.so im kinda freakin out right now
There will not be a re-broadcasting. The transaction is in the blockchain. It is now permanent, so there is no need for any wallet or peer to broadcast the transaction any longer. Whatever wallet has the private key for address: 19tK2WMKoxZ8GNRLBVRK3yecb79TQVJTKi has access to that 0.67 BTC, and that won't change until it is spent.
If a re-scan isn't working, then it sounds like there is either something wrong with the wallet (it could be damaged) or that address isn't a receiving address for that wallet.
Do you have the wallet password protected?
If so, then under the "Help" menu, in the "Debug window", is a "Console" section. In the console enter the following command:
walletpassphrase yourPasswordHere 300
replacing the word "yourPasswordHere" with your actual password. This will unlock the wallet for 5 minutes. If the wallet isn't protected then you can skip the walletpassphrase step and proceed directly to the following command, it it was protected then enter the following into the console within 5 minutes of entering the walletpassphrase command:
dumpprivkey 19tK2WMKoxZ8GNRLBVRK3yecb79TQVJTKi
If it responds with a 50+ character string that starts with either a 5, K, or L then the address is a receiving address for that wallet and you likely have some other problem. DO NOT ALLOW ANYBODY TO KNOW this string of characters that starts with a 5, K, or L. This is the private key for the address. Anybody that knows this private key can spend/steal your bitcoins (and all future bitcoins that are ever sent to that address). This private key can be used to import your address into other wallets if you decide you'd rather use Electrum, MultiBit, Blockchain.info or any of a few other wallets.
If it responds with an error, then let us know what the error is and we can try to help you figure out how to fix it.
