Whats the code like in your AddStudent Stored Procedure ?
If you're using a stored proc to do the add it would make sense to do a test in the stored proc if the user name exists, if it does then send a notification back to the application that the user name already exists and that the transaction could not be completed

|

well thats cool
i will send you the stored procedure code thanks
CREATE PROCEDURE AddStudent
@Name varchar(20),
@Username varchar(20),
@Password varchar(20),
@SchoolID int,
@ParentID int,
@Address varchar(20),
@LevelID int
as
insert into users values (3,@Name,@Username,@Password,@SchoolID,@ParentID,@Address,@LevelID,NULL)
GO

Declare @ExistUser varchar(20)
SELECT @ExistUser = Username from users where username = @username
IF(@ExistUser is Null)
Begin
insert into users values
(3,@Name,@Username,@Password,@SchoolID,@ParentID,@Address,@LevelID,NULL)
end
GO
This is something rough for you to use and give you an idea of what to do.
You'll have to elaborate a bit more on this

|

It worked, i dont know how to thank you!!
Where can i elaborate on this. ?
Estarta

Well you can think about passing back a FAILED or SUCCEEDED values back,
wrap it up in a transaction, there are thousands of possibilities, but you'll find out about them more as you progress.

Thanks alot 
i will try it now.

No, that's black.

No, that's white.

Make a loop from 0 to 0xffffff. If you want the hex value as a string, format the value using the "X6" format string.

hai sir/mam
When i close the internet explorer ..want to delete mytable records.....please help me

u can write ur code in onunload
|
|
|
|
|
in calender_render event, i control the days as:
if (e.Day.isOtherMonth) e.Cell = " "; (sth like that)
so users cant deal with the day of other months.. but when i turn selectmode from day to dayweek, the weeks of other months are seen too..
when calendar is like behind, there is no problem;
- - - - 1 2 3
4 5 6 7 8 9 10
.
.
.
31 - - - - - -
but sometimes it is like
- 1 2 3 4 5 6
7 8 9 10 11 12 13
.
.
28 29 30 31 - - -
- - - - - - -
"-" means, this day is not visible, not clickable..
when selectmode is day, we can see the days of prev or next month.. i hide it.. these days are in the same row with the days of current month, so it is not a problem to see that row..
but if selectmode is weekday, we can see te prev or next week of other months.. there is no day from current day in the row, so there is a empty row.. i want to hide this row too..
other month days are not clickable, those cells are empty and user cant reach.. but when user click on week,, user can select a empty row, even user cant select those days by clickingh on them, he can select them by clicking the week column..
there are 10 types of people in the world, those who understand binary numbers and those who dont..

Hello
I have a web page with different parts. In some parts of it, user can change the data of that. I put a button to save the data of each part, separately.
The user can enter new data without saving them. But I want to show a message to save them. The message should be shown when user closes the window or click some links.
This message should be shown client side. I know the command window.alert(...). I do not know in which JavaScript event I should show that to support every option of page transfer.
Please instruct me or offer me a different way.
Thanks
Rastgar

either <body onbeforeunload="functionName()" >
or <body onunload="functionName()" >
function functionName()
{
alert('pls save');
window.event.returnValue = false;
window.event.cancelBubble=true;
}
|

Thanks for your help.
Your code works very well. But when i use it, after alert 'pls save', I have another alert:
"Are you sure you want to navigate away from this page?
false
Press ok to continue, or cancel to stay on the current page."
it happens after code:
"window.event.returnValue = false;"
I don't want this alert to be shown. What should I do?
Thanks

Not possible to stop browser to close in JS. So u have to go with that extra alert.
