Solution 1

Start by reading up on the PrintDocument Class (System.Drawing.Printing) | Microsoft Docs[^] - that does the actual printing. What you print is up to you - we can't be specific because you don't give us any detail and we have no access to your data at all!

First off ... stop what you are doing, and urgently fix your whole app.
Never concatenate strings to build a SQL command. It leaves you wide open to accidental or deliberate SQL Injection attack which can destroy your entire database. Always use Parameterized queries instead.

When you concatenate strings, you cause problems because SQL receives commands like:

SELECT * FROM MyTable WHERE StreetAddress = 'Baker's Wood'

The quote the user added terminates the string as far as SQL is concerned and you get problems. But it could be worse. If I come along and type this instead: "x';DROP TABLE MyTable;--" Then SQL receives a very different command:

SELECT * FROM MyTable WHERE StreetAddress = 'x';DROP TABLE MyTable;--'

Which SQL sees as three separate commands:

SELECT * FROM MyTable WHERE StreetAddress = 'x';

A perfectly valid SELECT

DROP TABLE MyTable;

A perfectly valid "delete the table" command

--'

And everything else is a comment.
So it does: selects any matching rows, deletes the table from the DB, and ignores anything else.

So ALWAYS use parameterized queries! Or be prepared to restore your DB from backup frequently. You do take backups regularly, don't you?

When you have fixed that, you can start thinking about "improvements" but at teh moment, your whole app is a disaster waiting to happen...

The problem you have noticed is one thing. The problem you have is far greater and far more dangerous. When you have fixed that, you can move on to the one you have noticed - but it's pointless before that!
