Cant find the error:((

What line does Visual Studio tell you it's on when you run it?

You didn't new a command for cmd.

tnx bros i finally see it.,.,it line 23 )

One thing that's incorrect is that you need a ) after [Image] in your INSERT INTO statement

No value given for one or more required parameters

on my cmd.executenonquery

if i update data in database

Check through all your parameter values, as one of them seems to be blank. Also, I don't know if it is significant, but on line 34, @Password is not wrapped in [ ] whereas on line 27 it is.

i cant find blank sir.,.,because facultyid are autonumber

How can I fix a Javascript Application syntax error on Firefox Nightly?
