" searched a lot but i can't find it ", yeah right. One search 113000 results one of which is this http://www.codeproject.com/Articles/9021/Simple-and-fast-Huffman-coding

There is specifically nothing call ASP.Net language. Search related with the back-end of your application.

What is this beast -- ASP.NET language? There is no such thing. No wonder you cannot find anything. You need to look for Haffman code (pay attention for spelling: not "Hafman").

Pay attention to spelling: Huffman code. :P

Some humor won't hurt, believe me... :-)

Please understand that people's lough does not imply any disrespect to you, not at all; there is nothing more natural then being a beginner and asking questions, which are just bound to be somewhat naive at first, which is also quite natural. Seeking for knowledge is always respected...

After all, the main purpose of somewhat shocking sarcastic comments is to help you to realize things more clearly :-) and get to learning them with some productive results...

Ummmm , sorry but i don't agree with you .. you can make people understand better by correcting his information and guide him not by sarcastic comments .. that won't encourage him to ask again ,or specifically he won't deal with this site and those people again .. you can view your point easier by better words that will encourage him to deal with you more and you will get his respect to you , anyway i respect your opinion and nice to talking to you :)

Another alternative of course, is to use zlib. You'll not ever find a file compressed with Huffman that is smaller than the same file processed with zlib's deflate.

Here, lemme google that for ya[^]

From memory, in a worst-case, deflate adds at most 12 or 16 bytes to an input stream. Depending on the method of sharing the tree (either pre-defined or transmitted) you can find that Huffman behaves poorly or abhorently on (some) small files.

That's why zlib's deflate is used in everything from web-servers to mobile phones to png+jpg to pdf etc, etc.
