Go to the Bug&Suggestions forum and ask the admins, if you want.
For me, this topic is ended.
If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you
Rating helpful answers is nice, but saying thanks can be even nicer.
In a vb.net 2010 web form application that uses web form controls, there is a 'process' button where the user can click on the button lots of times.
This causes problems in the application for every time the button is clicked on, that many records are created in the sql server 2016 database.
I would like a solution on how to prevent the user from clicking on the button more than one time. I have a 'click button' code to catch when the button is clixked right away.
But I would like to know what I can do so the user knows they cannot click the button more than once:
1. I could make the button invisible.
2. However I would either like to have a popup message and/or somewhere on the webpage saying they can click on the process button only one time.
Thus can you show me the code on preferable setting up a popup menu? If not, can you show me the code on how to display the message on the web form page?
You're trying to access a web server running on port 58962 of your local machine, but there is on web server running there. We can't access your machine so we can't tell you why that is. Typically you only use non-standard ports when running the site in debug mode from Visual Studio. So either you are trying to access your site outside of VS, or VS's internal web server isn't working for some reason.
You need to look at the full details of the exception, including the InnerException, to see what the error is.
NB:SingleOrDefault will return null if there are no records. When you try to read the property on the next line, you could potentially get a NullReferenceException. It would be better to use Single in this instance.

Anything related to data and database connection should be placed inside your Data Access layer. Anything related to Business rules and validation should be placed inside your Business Layer or whatever you want to call it.
