How do I decode an image in Actionscript encoded in vbscript using MSXML?

I'm creating a Flash/Actionscript tool that displays data and an image on the screen. I have an ASP page that retrieves the data and sends it back to the Flash tool. I need to encode the image, using base64, in VBscript within the ASP page, then decode it in actionscript.

Currently I'm using MSXML to do the encoding in the asp page. I then wrap the encoded string in some XML, then use Server.URLEncode(XMLString) and write it out.

So, given this approach, what's the best way to decode the data into a byteArray for loading into an image on the stage? I'm currently trying to use, without success, com.dynamicflash.util, decodeToByteArray.

Is there a better way? The images could be fairly large. (They're photos people take using digital cameras so it's all over the map.)

Thanks!

'vbscript code in asp page

Function Base64Encode(inData)

  Dim dom: Set dom = CreateObject("MSXML2.DOMDocument.3.0")
   Dim elem: Set elem = dom.appendChild(dom.createElement("root"))
   elem.dataType = "bin.base64"
   elem.nodeTypedValue = inData
  
   Base64Encode = elem.Text
   
End Function
%>

Open in new window

//AS3 Code snippet:

	photoBA = Base64.decodeToByteArray(xml.BADGEREQUEST.PHOTO);

	requestPanelInst.requestPhoto.loadBytes(photoBA);

I finally figured out that MSXML conversion to base64 was inserting line feeds and + signs. It's obvious why the line feeds are bad news. The + signs are a problem because the dynamicFlash base64 decode expects a - (minus), not a plus.

Two replaces later and I'm good to go.
