The situation is I have to protect him now projects that reflect the sea is calling to fix security flaws in web
Eg when running web path
http://localhost:60864/DO_AN/Form_BA...px?MaBaiHat=11 (will appear 11 songs)
and he asks that if anyone entered
http://localhost:60864/DO_AN/Form_BA...aspx?MaBaiHat = '
or
http://localhost:60864/DO_AN/Form_BA...?MaBaiHat=null
web will surely fail immediately and ask them to remedy this error.
And also asked to make up their web network.
1 thing is that when people type in http://localhost:60864/DO_AN/ will see his form and took the code and data (images, for example) how to minimize this.
So I ask you any experience with their teacher at the only school I have not learned about these things but do not have time anymore
