Object Reference not set to an instance of an object 1

Afternoon All!

I hope this is the right forum, if not, please let me know!

I'm in the process of creating a VB, web based application, with an SQL back-end.

I have multiple forms completed and working fine, however, I now have an issue with the following line of code and I have absolutely no idea why!

Public constr As String = ConfigurationManager.ConnectionStrings("ABMSOPConnString").ConnectionString

Any advice would be gratefully recieved....any further information required then plase let me know.

Many thanks

Steve

Did you remember to put "Imports System.Configuration" at the top of the form code?

I did indeed Jebenson....that's what is more than a little confusing!

The only other thing I can think of is that you don't actually have a connection string named ABMSOPConnString in your configuration file.

Put a break on the line, and then set up a watch on ConfigurationManager, ConfigurationManager.ConnectionStrings("ABMSOPConnString"), and ConfigurationManager.ConnectionStrings("ABMSOPConnString").ConnectionString. This should tell you which part is null. I'll wager that ConfigurationManager.ConnectionStrings("ABMSOPConnString").ConnectionString is returning null, and that's why you're getting this error.

I'd step through a loop of the connections collection, to observe the Name of each
