Major topics covered in this class:

  • Contact Management
  • Creating a Contacts Table
  • Relational Database Concepts
  • Displaying Data from Multiple Tables
  • Creating a DLOOKUP Function
  • Contact Form
  • Creating Dynamic Dropdown Lists

In this class we'll deal with Contact Management, that is, storing different contacts for each of our customers. Every time I talk to Joe Customer, for example, I want to track in my database what was said, when we talked, and whether or not I have to call him back. That's contact management. We'll begin by making a contact table, and I'll show you how contacts relate to customers.

We'll talk about database concepts such as Relationships between tables, primary and foreign keys, and so on. We'll will create a page to list all of the contacts for a specific customer.

Next we'll learn how to create a page that shows information from multiple tables. For example, we'll display the specific contact information plus customer data (name) - pulling from both tables.

Because pulling information from multiple tables can involve a lot of code, I'll show you how to create a special function called DLOOKUP which will let you pull a field from a table with one line of code. We'll learn about variable scope (local variables inside a function).

Next, we'll make a contact form where we can store contact information, add new contacts, and edit existing contacts. I'll show you how to process the data once it's submitted.

You will next we'll learn how to create a Dynamic Dropdown List where the data in the list comes from a table. In this case, you'll fill the list with your customers so you can select a customer for a specific contact.

Finally, we'll work with text areas and check boxes and see how ASP deals with those.

You now have enough knowledge under your belt to begin building some serious web sites with ASP. You know how to set up a database, read records from it, edit records, add new records, and delete records. You can work with forms and different types of field types like text boxes, drop-down boxes, and so on.

Now you're ready to start building a full e-Commerce web site! That's coming up in the next couple of lessons.

jeff horvate on 6/4/2013: how do you turn on the line error checker in web browerss

Reply from Richard Rost:

What do you mean by the "line error checker?" Do you mean the JavaScript debugger or do you want to catch server-side errors in your ASP?

jeff horvate on 6/10/2013: my fault I use words. I want to catch sever-side error in asp?

Reply from Richard Rost:

This may be something you have to set up on your server and it's different based on your ISP. I use GoDaddy for example, and they have ASP errors explicitly turned OFF so that people don't see portions of your code (security risk). There's an article on their site that explains how to turn on custom errors.
