Hi All. Tore most of my hair out trying to solve this already! Please allow me to keep the remaining two :-)
What I am trying to do is use customValidator to go to a database via a stored procedure and fish out a UserName value. If it finds it, I want it to return 1 and if not I want it to return 0. On the ASP.NET page I have a field called user_username that customValidator is pointing to as a control to validate. The subroutine for the validator and my stored procedure are below. I now have 37 instances of the username = pkorolev and I get 37 as the value returned by the stored procedure, however the point where I want the validator to invalidate the page, the code fails. So, I get a correct value returned by the database (Enterprise Manager test), I get this value correctly on the ASPX page as output but the IsValid bit fails. What am I missing, seetings perhaps???? I bet it is something really simple.
*************** ********
create procedure userAlreadyExis ts
@user_username nvarchar(100),
@valid int output

declare @userValid int
select @userValid = Count(*) from user_pass
where user_username = @user_username
set @Valid = convert(int, @userValid) -- in this line i am simply trying to ensure that value coming back as an iteger

Hi Philip
what is the value of the @valid parameter when you debug your page could
you please debug and see if it will enter the if statement correctly

Hi Hussein.
Thanks for the reply. @Valid = 46. There are 46 instances of pkorolev which successfully made it though :-(
