I am making a chat application in VB.NET. I want to implement the smiley communication. Can anybody suggest the approach? If with code, then it is the best.

Make a list of charachters or group of charachters that represent smileys. And then when you recive them on the client you simply convert that to a image.

Allow write access for the user that the website is running as to the directory you are trying to write to.

I think that you have to provide more information.
Where are you trying to upload the file? To your own application?
Is the error message generated by the application, or are there any more information in the error message?
Is this a VB application, or would this question be better off in some web development related forum, like ASP.NET or Web Development?

What is it that you have a problem with, then?

b { font-weight: normal; }

If you search the articles here you wil find 10's of results showing linked list implementations.
If you expanded the same search to Google that number would probably be 1000's
