How to fix or add auto connecting to a server at game startup in counter strike 1.6, 1.7, 1.8 (tutorial)

This is a tutorial about how can you fix auto connecting to a server at game startup in cs 1.6, 1.7, 1.8 (it is possible to work for all the version as well), or how can you add auto connection to a server, or to set a control button to connect to a specific server in the game.

To remove auto-connecting:
Go to your main game directory/cstrike and search there for: USERCONFIG.CFG, AUTOEXEC.CFG, AUTOCONFIG.CFG, CONFIG.CFG, and open each and every file at once and look for a command called "Connect ip_address" (Example: "Connect 89.1.2.3:27015"), remove those commands from each and every file, and save the changes. Be sure that each and every file is set to be modified when you take the changes (make sure that those files are not set as read-only from the proprieties). After taking these changes, and saved the files. Check the cstrike folder for any other similar cfg files (if you find some you can delete them.)
Also you to avoid for the future that to happen again select all the fresh modified files at once and make them Read-Only from their proprieties.

To add auto-connecting:
Go to your main game directory/cstrike and search there for AUTOEXEC.CFG or AUTOCONFIG.CFG (you only need to find one of these two), if you found the file open it with notepad, if you can't find the file right-click somewhere inside the folder and create a new .txt file name it AUTOEXEC.cfg (don't forget to change the extension from .txt to .cfg), then open the file and write inside it: Connect ip_address_of_the_wanted_server (Example: Connect 88.1.2.3:27015) it works with the dns address as well: Connect cs_server_name (Example: Connect cs.game.com). Once done than, save the changes and mark the file as read-only to avoid being effectuated changes while playing on a public online server.

To add auto-connecting by pressing a button:
Go to your main game directory/cstrike and search there for config.cfg, (or any other file that you use as main cfg while playing). Open it using notepad and check for the button that you want to add the command. Example if I want to add the command to F5, I will search for the line: bind "F8" "Connect server_ip" and complete there instead of server_ip with a valid server ip address, (Example: bind "F8" "Connect 93.119.24.41:27015"). Also you can add a command for a button that you can't find it: If you want to add the command for the button K, but you couldn't find K in the whole document, write this line:
bind "K" "Connect server_ip", after making the changes be sure you save the file and
make it Read-Only from its proprieties (to avoid the file taking changes while entering a public online game server).
