Examples: GetParameterName method

This example shows a form action (the Click sub) that sets the parameters for the SQL query in the Postopen sub. Although the query in the Postopen sub contains exactly two string parameters, the action works for a variable number of string parameters. The Click sub uses the GetParameterName method to prompt the user for a value for each parameter value.
