    You need to single-quote the string you're trying to match...

    Dim strSelectName As String = "SELECT * FROM tblNames WHERE [name] LIKE '%" & txtExecuter.Text & "%'"

    You also need to call something on txtExecuter.Text to escape any special characters (like quotes) in it too, if this code is for real-world use and you're not already validating it in a way that excludes that. Otherwise you've got an SQL Injection security hole. :-)
