The following example shows how you can pass FlashVars from your HTML template to your Flex applications using the Flex 4 SDK (which uses SWFObject now, by the way).

Full code after the jump.

To use the following code, you must have Flash Player 10 and a Flex 4 SDK installed in your Flex Builder 3. For more information on downloading and installing the Flex 4 SDK into Flex Builder 3, see “Using the beta Flex 4 SDK in Flex Builder 3″.

And my [slightly modified] HTML template code is as follows:

  userAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; GTB5; .NET CLR 2.0.50727; .NET CLR 1.1.4322; .NET CLR 3.0.04506.30; .NET CLR 3.0.04506.648)"
  userLanguage = "en-us"

This entry is based on a beta version of the Flex Gumbo SDK and therefore is very likely to change as development of the Flex SDK continues. The API can (and will) change causing examples to possibly not compile in newer versions of the Flex Gumbo SDK.
