@xylenedz One of the possible reason is that your command’s query may have returned no value….make sure you’ve typed your query right in string format with proper punctuations.

@Shmv90 Sure…

I wrote the code for the login page exactly similar to what you have done in you demo. similarly the login website part 1, 2 and 3.

After i have finished with part 5 and made login page as a start page. i clicked on debug botton so i have got an error in the login page code. The error message was ” Cannot implicitly convert type ‘string’ to ‘bool’ ”
when i clicked on the msg it highlighted this part of the code:
” string password = Pass.ExecuteScalar().ToString(­);”

Hi shamv,

I’m facing an error

Cannot implicitly convert type ‘string’ to ‘bool’

this error concerning line: password = TBPassword.Text
which is related to line: string password = Pass.ExecuteScalar().ToString();

what do you thin the problem could be

Thank you

@DoctorM64 It’s a good practice that you add con.close() in finally portion of try catch block. I’m sorry I must have forgotten that to add in this video.

@dementorspirit my pleasure…

Hey
I am getting an error at line
string Password = pass.ExecuteScalar().ToString();

error:Object reference not set to an instance of object…

please help!!

Thanks, 4 the Vid men… Nice…

@Slicez0r: Yeah, it’s right…!!

@prakash4everything: I think you should use javascript’s _doPostBack function in your code. Search for it in google for how to use it in detail.
