Creating your .NET Class to Invoke from Flash

In this tutorial you will create the RemoteCatalog class, which returns a

recordset from the sports database.

Although we will only be using a simple .NET Class in this example, there

are several ways to retrieve dynamic data in .NET and make it available to

Flash Remoting, including ADO.NET, ASP.NET, Web Services, and

DLLs. (You may refer to Chapter 7: Using Flash Remoting MX for .NET

in the Flash Remoting documentation for additional information).

Steps

The following needs to be performed by you:

• Examine the C# code that is provided with the tutorial

C:\Inetpub\wwwroot\flashremoting\samples\flashwidgets\RemoteCatalog.cs

• Compile the C# code into a Class file and locate it in the local

assembly where the .NET server can find it.

C:\Inetpub\wwwroot\flashremoting\samples\flashwidgets\RemoteCatalog.dll

Examining RemoteCatalog

The following is the implementation of RemoteCatalog that connects to the

“sports2000” database and contains:

• A method getCategories() that retrieves all the categories of products.

This method queries the category table and returns a recordset

containing all categories.

• A method getProductsByCategory(int catId) that retrieves products

for a given category. This method queries the product table returning

all products for a selected category.
