C# - SqlTransaction has completed

[limok]

Hi,

 

I'm having trouble with the code below used in a .Net 4.5.2 website. The error I get is that the sql transaction is no longer useable. I'm guessing the first insert is failing and the app isn't rolling back the transaction properly.

 

Secondly - the bizarre thing I can pass the exact same values from one machine that will work but from another machine it will not.

 

if you need more info ask away.

 

thanks.

using (SqlConnection connection = new SqlConnection(cs))
            {
                connection.Open();
                SqlCommand cmd = connection.CreateCommand();
                SqlTransaction tran;

                tran = connection.BeginTransaction("sampleTransaction");

                cmd.Connection = connection;
                cmd.Transaction = tran;

Um, don't forget that if you have critical code in a Javascript button click event it will not execute if the user submits the form using the Enter key...

That isn't a client side click event.

It's been so long since I have done the ancient ASP.NET WebForms with all of it's behind the scenes wizardry. That control will generate a payload of Javascript code to do all sorts of client-side things which presumably will handle the enter key along with a host of side effects that are version and patch level dependant and a whole host of other fun stuff like ViewState in the megabytes and gosh it was all an impressive accomplishment in some weird mad scientist kind of way that I still have a tiny soft spot in my heart for but would not be able to bring myself to actually use again because the mad scientist in me would also insist on a WPF XBAP payload which was the most beautiful thing you could deliver in a web browser and then HTML5 dumped the ugliest possible acid trip of cobbled together programming on us as a blight upon humanity for sins we couldn't possibly have committed...
