    So a few questions:

    1) Why would you want to base64 encode your flash file?

    - Base64-encoded data: URIs are roughly 33% larger in size than their binary equivalent
    - Browsers may limit URI lengths, creating an effective maximum data size. For example, URIs in previous versions of Opera had limits of 4kB, and 32kB for IE8 Beta 1
    - Microsoft's Internet Explorer, as of versions 6 and 7, lacks support

    2) Not working in what?


    You might have to break the base64 stream into lines of 76 characters, as described here:

    "i want to put clipboard.swf in js body to reduce quantity of request to server".

    But if it is in the body of your HTML page, then you are still putting load on the server. Are you worried about the number of requests vs size of request? This is like saying I want to make my whole web page 1 image to reduce the number of images being called on the server. It just doesn't really make sense to me...

    On standard browsers, once a user has called the .swf once, then it is in their cache and there is no more calls to your server.

    Anyhow, I have never used data URI before, so I can't really help you on that. I'd suggest getting it working with the standard Adobe object/embed method and then porting it to swfobject afterwards. Basically reduce your problem to it's simplest form. It doesn't help that you are writing the swf at 0x0 pixels, so you never even know whether it was ever created or not...
