What I am trying to is automatic bidding process in Ebay site...
WebClient class can uploads form data easily.
I have collected ebay url & form data to uploads..
Most of process is quite easy and simple. But ebay webserver send me your password is not valid...
But the password is clearly correct.. you can type it at the result page and submit. Then you can see a message - bidding has ended and you are logged in. <- This is the message I want.
I can not find where is a wrong part. Some code is worng?? Or whole different way..? Please help me~~~~
