This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind.
Assuming this is an Article on Codeproject, the best thing to do is either ask using the "new message" button at the bottom of that article, which causes an email to be sent to the author. If that doesn't work, then you need to ask here:
