Now, we just give our error a name and look for it. Besides the classes, you will also build a number of new pages to deal with the new types of data. You’ll link these pages into the main address book viewer, since the other two entities are “child” entities; that is, a contact can’t exist by itself without a related person record. The steps for this project are: Contact Manager Application 1. Set up the development environment. 2. Build the Database class and test it. 3. Build the BaseServices class and test it.
If we are in “posting” mode, we make a database connection using the SqlConnection object. We have to provide a connection string, which specifies which server and which database we want to use, as well as the user name and password to use for connecting to the database. We then start building the SQL statement using a StringBuilder object. We then run the query using the ExecuteNonQuery method and send the user back to the appropriate list window. This has the effect of refreshing the list window and making the new record visible.
This class manages the data in the tblContacts table, which you’ll be creating in this project. Any detected errors will generate a ContactException error. Note. This class handles the tblNotes table, which you’ll also be creating in this project. Any errors cause a NoteException error to be raised to the calling code. PersonException, ContactException, and NoteException. NET Framework programming is the highly structured error handling process. In this project, we’ll create four of our own errors.
