I don't think it is IE the one that dictates the component is outdated.  I think webpage developers include this check in their Javascript.  I could be wrong, though, I would love to hear a different opinion.

It's not IE, it's Adobe Flash Player itself which determines that it is out-of-date, or can't handle the object data embedded in the web page.

Please do not multipost, unless you copy in the hyperlinks to the other posts. It is very aggravating for posters to research answers only to discover that the question was answered elsewhere. Be considerate of other people's time.

The current version number is in the Version resource of the control's DLL.

The HTML of the page uses codebase= attribute of the <object> tag to specify the minimum required version number, and tell the browser where to get it if necessary.

2) Which are interfaces need to be implemented by a ActiveX to support this kind of behavior

None.

Hi Igor and Jose,

Thanks for your reply.....

I had gone through the link specified by Igor....It is good....But it is obsolete as of IE 7.....

Before implementing this kind of logic I am trying to understand How Flash ActiveX works with respect to downloading a new flash player version......

For Ex:

1) Just type Youtube

2) In the first page of youtube, there is a flash

3) Open the source code and it looks like they are detecting the flash version using scripts....

Could you please help me to understand how they are doing??

Thanks & Regards,

Ramanujam

Hello,

As far as I know, you can use JavaScript to get the Flash Player version. Please follow the Retrieving Flash Player version info section in this document

Hello,

As far as I know, the function to get the Flash version is provide by the Flash object which is an ActiveX control. This function is defined in ActiveX control.

I think the JavaScript function should be the same in the different website, because the public function in ActiveX is fixed.

For more information about how to call the ActiveX function through JavaScript, please check this thread.
