This is a little “Hello World!” with a button tutorial for Jeff, since he was having trouble with Flex. So, Jeff, start a new project in Flex Builder. Let’s call it, “HelloSape”. Now, go to the Design view of HelloSape.mxml and drop in a Label, fill in the ID with “sapeLabel“, and fill the Text with “Hello Sape!“. Now drag in a Button next to the Label, fill in the Button Label field with “Goodbye!“, and fill in the On click with “DoClick()“. Switch to Source view.

Enter this code above the Label:

<mx:Script>
<![CDATA[
private function DoClick():void
{
sapeLabel.text = "Goodbye Sape!";
}
]]>
</mx:Script>

Save and run the application! Click the button and it should change the label!
