Flash Pro or Flash Builder to make graphical web widgets with sockets?

I've contacted Adobe sales and tech support, and realized that I need t开发者_如何学Goo talk to someone who actually develops with these tools.

I want to develop some simple graphical widgets with the ability to reload themselves via an xml-socket a couple of times a second. Which Adobe tool should I buy-- Flash Builder, or Flash Pro?

As you'll need to write quite a bit of custom code, you'll want to have Flash Builder available. Note, however, there is a free SDK available that will allow you to do what you need, so you don't actually need it.

Here's the documentation on Flex 4's XMLSocket. Note that use of XMLSocket requires a policy file on the server that allows such a connection. Another option is to use Javascript through the External Interface API for those browsers that support it.

Depending on your widget, it may be useful to have Flash Pro, but it's not strictly necessary. Flex Builder does support building UI's and widgets. At worst, you'll just need to write the code for it.
