[SWFObject] Flash detection problem

Tue May 9 15:39:56 PDT 2006

DOH... I read your email wrong. You were saying version 6 of IE, not the
player... Either way, this is important info for everyone to know.
Although it may not apply to your current problem.

This is a known issue with the detection that SWFObject and the
Macromedia Detection kit use. The axo.GetVariable("$version"); call
crashes Flash Player 6.0 prior to version r47. So we created some work
around scripts to default to specific values if we can figure out that
you have a player that will crash or have problems with the simpler
GetVariable path. This script will be made public in a few weeks after
we have completed testing. Geoff might want to take elements of it and
add them to the SWFObject since I know he has had the same issue. Just
make sure you give attribution to Adobe. 

Here is the updated script. DetectFlashVer(reqMajorVer, reqMinorVer,
reqRevision) is the main function:

// Flash Player Version Detection - Rev 1.5
// Detect Client Browser type
// Copyright 2006 Adobe Systems, Inc. All rights reserved.
var isIE  = (navigator.appVersion.indexOf("MSIE") != -1) ? true : false;
var isWin = (navigator.appVersion.toLowerCase().indexOf("win") != -1) ?
true : false;
var isOpera = (navigator.userAgent.indexOf("Opera") != -1) ? true :
false;

function ControlVersion()
{
	var version;
	var axo;
	var e;

	// NOTE : new ActiveXObject(strFoo) throws an exception if
strFoo isn't in the registry

	try {
		// version will be set for 7.X or greater players
		axo = new
ActiveXObject("ShockwaveFlash.ShockwaveFlash.7");
		version = axo.GetVariable("$version");
	} catch (e) {
	}

	if (!version)
	{
		try {
			// version will be set for 6.X players only
			axo = new
ActiveXObject("ShockwaveFlash.ShockwaveFlash.6");

			// installed player is some revision of 6.0
			// GetVariable("$version") crashes for versions
6.0.22 through 6.0.29,
			// so we have to be careful. 

			// default to the first public version
			version = "WIN 6,0,21,0";

			// throws if AllowScripAccess does not exist
(introduced in 6.0r47)		
			axo.AllowScriptAccess = "always";

			// safe to call for 6.0r47 or greater
			version = axo.GetVariable("$version");

		} catch (e) {
		}
	}

	if (!version)
	{
		try {
			// version will be set for 4.X or 5.X player
			axo = new
ActiveXObject("ShockwaveFlash.ShockwaveFlash.3");
			version = axo.GetVariable("$version");
		} catch (e) {
		}
	}

	if (!version)
	{
		try {
			// version will be set for 3.X player
			axo = new
ActiveXObject("ShockwaveFlash.ShockwaveFlash.3");
			version = "WIN 3,0,18,0";
		} catch (e) {
		}
	}

	if (!version)
	{
		try {
			// version will be set for 2.X player
			axo = new
ActiveXObject("ShockwaveFlash.ShockwaveFlash");
			version = "WIN 2,0,0,11";

			version = -1;
		}
	}

	return version;
}

// JavaScript helper required to detect Flash Player PlugIn version

Subject: [SWFObject] Flash detection problem

I have beating my head against a Flash detection problem for a few days.

I've downloaded swfobject.js and followed the instructions on how to use
it. However, the Flash detection fails in a specific version of IE
(6.0.2900.2180.xpsp_sp2_gdr.050301-1519) with Flash Player 8.0.24.0
installed.

Has anyone seen this problem? Any advice you can give would be greatly
appreciated.

Thank you,

Lacy Garrison
