Because when I did that it showed me that the btc addresses are there in the wallet, but balance is still 0.00
you need to run it with the rescan option so it will go through the block chain and find all of the transactions for each of the addresses in your wallet.

I suggested that 2 days ago:
If you are using a version older than 0.7.1, I'd try the -rescan option on the command line when starting up Bitcoin-Qt.
Actually, even if you are running 0.7.1 or 0.7.2, I'd probably still try it even though I don't expect it to help under those circumstances.
You're not listening to Danny, and you're not listening to me it sounds like. Rescan it. If blockchain.info import gives you access to your funds, the only reason you couldn't see them on qt is because you replaced the wallet.dat file and then opened it up. That would show you your addresses, but your balance will be 0 until you rescan.
It is not something you can do from console, you have to set that parameter during start up.
You need to sit down and read these top to bottom:
