Question : Crystal Report in ASP web app Error Login failed for user 'MYDOMAIN\username'.

Hi all,

I created a crystal report and deployed it to a test server, i call it from my web application by clicking on a button, when I do I get an error on the page (See Attached)

The thing that confuses me is I tried logging into the database using the same user and I was able to!!! is something wrong with permissions or my connection string?

Connection string looks like this:

Conn.ConnectionString = "Data Source=servername;Initial Catalog=xxxxxx;Integrated Security=False;user id=MYDOMAIN\\username;password=sssssss;";

Answer : Crystal Report in ASP web app Error Login failed for user 'MYDOMAIN\username'.

I wouldn't attempt to combine both triggers and the use of a data layer such as nhibernate - you're always going to get synchronisation problems. nHibernate is intended to manage your data - and your business layer should manage processes such as updating your prices. Personally I don't go near triggers for any business logic - for auditing perhaps, but nothing else. I think they obscure business logic and make it nigh on impossible to implement other code solutions for managing the data - as you are finding.
Why not move your trigger code into a stored procedure and call the procedure from within the transaction scope of the update if the 'finished' flag is true? I would manage this within the business layer, but you could move this to the data layer if you wish.
