as you can see from the number of replies I have made in this post, I *am* trying to help. However this is just a personal blog and not a question & answer site (like, say, StackOverflow).

I have presented here a possible solution to a problem (sending files via WCF), hoping that this would inspire other people with similar problems. I am not a Microsoft MVP.

It seems, though, that you need something more and you expect me to provide the solution to your specific problem. I don’t have code ready to solve it and it would take me hours just to understand your scenario, put the code together and test it until it works correctly.

I think you would like to just write a word a two if some one makes some post. Not interested to solve their exact problem. Please intimate what is the use of providing a provision to post a comment when you are not interested to provide some sort of solution.

I have been waiting for your response for the past one week.
If you are not interested to post anything, Please remove this comment box altogether and just share your experience.
