Hi Roleg,
I'm trying develop same function to get vin address from public key by using c++, while coding i tried pub key mentioned above in this post and generated sha256 but i'm getting different output.
(output: 36bdb67e9a379df3e208ab87941d7320aabde7204f6eb4a1b31660804f958c15). I have used openssl/sha.h for sha256. It would be great, if you could tell me how you got that sha256 value from pubkey this pubkey (022e2531ee7a16dbaf83e3554334bb6adea93af0fb2f221cb17b9ffbb587e6bb7f).

Wow
the 00 in front, added in step4, will likely be something else
It is 48 (decimal) - replace 00 with 30 and you will get LWnHG9iyy1KVbG8JmhDiFe5QVQdZnxtqGW
OMG !You My HERO!!!
snks!

It is 48 (decimal) - replace 00 with 30 and you will get LWnHG9iyy1KVbG8JmhDiFe5QVQdZnxtqGW becouse I send from LWnHG9iyy1KVbG8JmhDiFe5QVQdZnxtqGW
but Litecoin proto
Well, then you should have told us that you meant litecoin, not bitcoin.but Litecoin proto
I don't know litecoin address specifics, but I guess that there should be at least a different "version" byte (the 00 in front, added in step4, will likely be something else).
becouse I send from LWnHG9iyy1KVbG8JmhDiFe5QVQdZnxtqGW
but Litecoin address to Litecoin address
but Litecoin address to Litecoin address
but is not true 
It is true - that's the address.Why do you think that it isn't?

I want recover sender address from this transaction.
There is no from address. It is clear what you are asking for, but not why you need it or why you believe it is the "sender's address".
You may find it worthwhile to read http://download.wpsoftware.net/bitcoin/bitcoin-faq.pdf .
I want recover sender address from this transaction.
The public key isn't stored in a transaction or the block chain, but it's hash is. Normally blockexplorer or something will pick out the public key from the signature when spent (you're looking for the public key for the sender, who has just signed the transaction with this part:)
Can't get onto explorer.litecoin.com right now but it might help you when it gets back up..
