Without knowing the exact error message, or having any access to your DB we can only guess.
But ... VB array indices are zero based: so
GetString(1)
may be wrong, and you have not read any rows from the reader (or checked that there are actually any rows returned).
Two other things:
1) Using an Access DB in a web based project is a bad idea: while access can be used by multiple users it's generally a pain - particularly when you keep the connection open forever. I'd strongly recommend that you look at
Using
block around your DB code, and replace Access / OleDb with either Sql Server or MySql as they are designed for multiuser access.
2) 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?
