thx saved me a bunch of time =)
hey lakshmikanth reddy
In the HTML tag that embeds your SWF, check its PARAM tag for the property -
allowScriptAccess. It should not have a “never” as a value. It can have
something like “sameDomain”.
I tried running the above example..and it worked fine….
But when I integrated the .swf in an .html file within the <object> tag as:
<object id="swfembed" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="100%" height="100%"> <param name="movie" value="bin/testbanner.swf" /> <param name="quality" value="high" /> <param name="allowScriptAccess" value="always" /> <param name="wmode" value="opaque"/> <embed id="swfembed" name="swfembed" src="bin/testbanner.swf" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" allowScriptAccess="always" wmode="transparent" quality="high" width="100%" height="100%"> </embed> </object>It worked fine with Mozilla but not in IE6/7!! :(
What needs to be done???
it didnot work for me in FF 3.5 also :(
@Stanislav, Zeba: IE uses a different tag for embedding Flash contents, <embed/>. See http://www.verticalmoon.com/tutorials/general/flashhtml/flashhtml.htm
Don’t try the clever stuff, they don’t work all the time, especially on IE. Even the unclever stuff don’t work on IE sometimes. IE is just a piece of crap
I took the same mxml file and ran.
On IE 6 its working … But Its failing If I run this example in Firefox.
Following is the error its showing up.

Please help me out.
@kumar,
Try running the example from an HTTP:// address rather than file:/// address.
