Excerpt

The Business API does not return any error codes. All error handling is done by exception. This implies that the business system developer should wrap all method calls and accessing properties. Besides the standard exception defined in .NET, the Business API also defines a number of exceptions. For a detailed description of exceptions please refer to the Programmers Reference to the Noah 4 Business API.

The following sample code shows how exception handling is implemented in the sample business system when using the remove method for unboundactions.Image Removed

Info

private void Remove_Click(object sender, EventArgs e)

        {

           int index = Convert.ToInt32(this.textBox2.Text, 10);

            {

                if (m_actionType == "Actions")

                {

                    m_Session.Actions.Remove(index);

                }

                else
