Source Files - http://www.jmanproductions.com/Source.zip
Good afternoon,
I’m trying to recreate a Flash/ASP.net File Upload tool that I saw here:
http://www.codeproject.com/aspnet/FlashUpload.asp
This version was done with Flash 8, so I wanted to recreate it using Flash CS3 and AS3.[URL=“http://www.jmanproductions.com/Default.aspx”]
So what’s my problem? Well The version above uses parameters sent to the flash player that the flash player uses for the upload method. Well I’m having trouble pinpointing my problem with the following code in bold. When I test it in Visual Studio nothing happens I can’t seem to figure out how to trace the value of the parameters, which are also below the code. so if anyone could point me in the right direction, or download the source, and help me out, I would much appreciate it.
Thanks!

Adding the flash uploader to the page. <param name="wmode" value="transparent"> makes
the movie transparent so any page styling can shine through.
FlashVars is set to pass in the upload page and a javascript function if desired.
The javascript function fires when the upload is completed. This allows us to
call a codebehind function to refresh a gridView or anything else.
A link button is used to perform this function. The javascript is added in the pageLoad
in the code behin.
