Passing Parameters to Flex

Adobe Flex is a great way to do Rich Internet Applications (RIA). When you need to pass a parameter the flex flash movie, you can do that simply by adding a line in the generated script tag.

...
} else if (hasRequestedVersion) {
    // if we've detected an acceptable version
    // embed the Flash Content SWF when all tests are passed
    AC_FL_RunContent(
        "src", "Main",
        "flashVars", "i=15&employeeName=xyz", // add this line with the vars you want to pass
        "width", "100%",
...

Then, in flex, you can access this parameter as follows:

application.parameters.i
