[F8] ExternalInterface with C#.NET ActiveX Container

[howoong]

I want to transmit JPEG image data from C# to Flash SWF, in order to display it in SWF.

After I had written a JPEG data as a file on hard disk in C#,
I sent the filepath to Flash SWF, by using AxShockwaveFlash like:

xmlRequest = 
  "<invoke name=\"DisplayJpeg\" returntype=\"xml\">" +
  "<arguments>" +
  "<string>C:\\temp\\thisimage.jpg</string>" +
  "</arguments>" +
  "</invoke>";

xmlResponse = oAxShockwaveFlash.CallFunction (xmlRequest);

And, in the ActionScript file in Flash, I used following code:

import flash.external.ExternalInterface;
...
ExternalInterface.addCallback ("DisplayJpeg", this, doDisplayJpeg);
...
public function doDisplayJpeg (filePath:String):Void
{
  aLoader.contentPath = filePath;
...
}

It works fine, but it takes longer time due to the disk write/read operations.

Is there any way avoiding disk write/read to display JPEG image in the Flash SWF?

[Q1] Can I send binary data through AxShockwaveFlash CallFunction, from C# to Flash?
[Q2] Can I get the binary data in an ActionScript variable in Flash; and display it thru Loader, or thru other component?

Thanks,
Joseph

I know this is a very old post but It may help someone.

In terms of passing binary data, you can set the value of a textbox "VBCalling" in Flash from VB using something like this:

Call AxShockwaveFlash1.SetVariable("VBCalling", 1)

If you are looking to send a string you could do something like this:

Call AxShockwaveFlash1.SetVariable("VBCalling", yourString)
