i have a very big file
C:\Program Files\MySQL.txt
it is about 12.2 GB
what is this file? and should it be there?
because i could use such a space. :)

It is not a "standard" MySQL file, look inside maybe it is a backup dump left there. However i think you can delete it without breaking anything.

A MySQL log file holds all the transactions happening through MySQL.
As u mentioned its 12 GB I don't think so it will be easily handled by any software to read the contents inside it.You can delete it without affecting MySQL.

I was wondering how MySQL (and other databases for that matter) work under the hood. Do they use standard C I/O calls like fseek to find a record?
Here is the link to the source code. From a quick review of the file I can confirm that there are multiple check that is been done before and after an insert. It's actually a great idea to review the whole file very interesting.

Unfortunately i have dropped all table from a database of a WordPress website, but i have not any backup. Is it possible to restore all table from cpanel without backup?
Please help me.
I'm sorry to say that without a backup file there is nothing you can do. Did you try contacting your hosting company to see if they happen to have a backup? Sometimes they do.
I wish you luck.

i have some questions regarding linq to sql with c#. hope you can help...
Does creating Data base new DataContext load the entire DB to local cache every time?
If the answer is yes, Is there a way to Load Only the required part of the DB(with Querys Or Stored procedures maybe) to do so ?
3.Does Linq To Enteties is more suitable for this requirements ?
1/ No, it does not load anything from the Database untill the query is executed
2/ ...
3/ You can load the entire database in Cache if you want to. BUt that has nothing to do with Linq-2-entities or Linq-2-sql. You can do it with either technology.

I need reproduce the exact same environment of a system in production, it's working with mysql 4.1.3b-beta-nt-max version, where I can get this exact version? I have looking with google but it seems like it's no longer available anywhere.
Thanks.
Try searching historical databases such as
http://www.oldapps.com/mysql_server.php?old_mysql_server=131
...in a pinch, you can install a "similar" version (such as the one above, 4.1.3beta-win), and then replace the binaries with the production ones. MySQL doesn't do strange things with the registry, so this procedure should suffice.

When I actually write in the wiki, where are the changes actually being stored?
I have searched the source code for keywords that i have actually written and i cant find it, which obviously means its being stored where it cannot be searched directly.
I have made changes to it i.e. written in it, but sourcetree does not seem to be recognising it.
Do you mean the site's contents? They are stored in a database file which is read and written by the code.
It would be quite unmaintainable, if not outright dangerous, to mix user-submitted data with executable code.
They are stored in a database table called page (or something similar)
