how to access controllers in 'admin' directory

[eluser]Blue Sapphire[/eluser]
Thanks for the reply, but it didn't work. Actually my problem is that, my urls are containing variable like as follows:

http://localhost/main/forum/admin/user/view
http://localhost/main/forum/admin/user/create
http://localhost/main/forum/admin/user/d...me/my_name
http://localhost/main/forum/admin/dashbo...hird_var/4

So from above examples, you can see that urls are very dynamic in nature.

Can you suggest me some solution, keeping in view the above examples.

Thanks in advance
