Benefits

The Flash Remoting code in this version is more intuitive; it defines a component

containing a function that accepts two arguments directly from Flash. There is no

manual parsing; the arguments to the function are passed as strings and a recordset

is returned. If the recordset contained 15 fields and 1,000 rows, the server-side code

would not look much different.

Using Flash Remoting is much simpler because the Flash movie does not have to

package the request in any special format such as XML. Likewise, the ColdFusion

Server does not have to package the result for the Flash movie. The data is simply

passed back and forth as is and put to use. It is the difference between having a pizza

delivered and making the dough and baking the pizza yourself. If the pizza is deliv-

ered, the only action you have to take on the pizza is to eat it.

Manually serializing and deserializing data has the advantage of working with Flash

Player 5. However, when you consider the amount of client- and server-side code

that you have to write, debug, and maintain just to provide basic support for serializ-

ing one datatype, the advantages of Flash Remoting become clearer. Considering all

the datatypes that Flash Remoting supports and the fact that you can call remote ser-

vices by name without writing any extra server-side code, Flash Remoting becomes

quite attractive.

HTML and Server-Side Code

A typical HTML/server-side template application has problems similar to those in

our XML example. The server-side code does not simply perform logic and return

information; in many cases, it formats the data as well. Take this simple ColdFusion

snippet as an example:

SELECT Title, Category, Pub_No FROM Books

WHERE Title LIKE '%#form.searchfield#%'

</cfquery>

<tr>

<td>Title</td>

<td>Category</td>

</tr>

<cfoutput query="rsGetSearchResults"

startRow="#StartRow_rsGetSearchResults#"

maxRows="#MaxRows_rsGetSearchResults#">

<tr>

<td>#rsGetSearchResults.Title#</td>

<td>#rsGetSearchResults.Category#</td>

<td>#rsGetSearchResults.Pub_No#</td>

</tr>

</cfoutput>
