There's your first problem: consider what happens if there's an apostrophe
in one of the names: it will break your SQL string. Or worse, your database
could be the victim of an SQL injection attack.

You will need to use a parameterized query. I can't find a basic explanation
quickly, google has the answer somewhere.

And if you're using SQL Server, you might as well go through
System.Data.SqlClient rather than OleDb.

You did not needed to use a SP , you could have done it with a
parameterized SQL command ( although a SP is fine )

But if you were really smart , you would have used the datadapter from a
dataset as you then get the benefit of strong typing in your code
add a new dataset to your project , go to design view , add a new datadapter
and use the wizzard , select your base Table or View
now you can extend the table adapter with anny query you like parameters are
typed with a @ prefix in SQL server in Access ?

also another remark a textbox is returning a string so why convert a string
to a string ?
