I have an application that uses an HTML container to load a webpage with a
flash SWF embedded into it. I want to bundle the webpage and all of its
resources (including the SWF) into a resource DLL, which makes it accessible
from the HTML container using the res:// protocol.

E.g. c:\MyResources.dll contains MyPage.htm, MyScript.js and MyFlash.SWF. In
Internet Explorer I can use the URL res://C:\MyResources.dll/MyPage.htm to
load my page.

However when I try to load my SWF file in the page, it can't find MyFlash.SWF.
I would expect to be able to use the normal method to load the movie as the
SWF exists in the same effective namespace as the htm file - attached code
example. MyScript.js is loaded from the resource just fine.

I also found that I couldn't reference the SWF explicitly from the resource in
a webpage that exists outside of the resource by using
res://C:\MyResources.dll/MyFlash.SWF in the object/embed tags. However if I
type the same string into the address bar, IE will prompt me to download the
SWF file, proving that its there and accessible at least.

Am I doing this wrong or does the flash plugin simply not support loading
content from within resource DLLs?


<!-- this js file runs fine -->
<script src="MyScript.js" language="javascript"></script>

<!-- but the flash movie won't load -->
<object width="550" height="400">
<param name="movie" value="MyFlash.SWF">
<embed src="MyFlash.SWF" width="550" height="400">
