I cannot see any txt declared in the screenshots. It could help if you explained why you think the above should work.

Most likely, you have already solved the problem. Otherwise, go to the “Form1.cs [Design]” tab and clarify the name of controls. The form should contain textboxes for username and password. For example, if a name is “txtUsername”, then change the problematic line to username = txtUsername.Text.

And use parameterised SQL queries, by the way.

Hi @Kio ,

Ensure that the name is spelled correctly and matches the case exactly as defined. C# is case-sensitive, so txt and Txt would be considered different names

Try clear and rebuild the solution.

Best Regards.

I don't see anything SQL Server related.

And you get the error because by your screenshot the variable/object "txt" is nowhere declared.
