I have a html file located on the machine. The html looks like this.
<BODY bgcolor="#000000">
<embed src="C:\something.swf"
height="768" width="1280"
type="application/x-shockwave-flash"
bgcolor="#000000"
wmode="direct"
flashvars="liveUrl=C:\data.xml"/>
</BODY>
C# Code:
WebControl.WebView.Url = "C:\sample.html";
Sample html successfully loads, and "something.swf" also successfully loads. I can see the content on the webview. However part of the content is also driven by "data.xml". The issue I'm having is something.swf can't seem to access data.xml, which is also stored locally.
This works if I hosted something.swf and data.xml. Example:
<BODY bgcolor="#000000">
<embed src="localhost://test/something.swf"
height="768" width="1280"
type="application/x-shockwave-flash"
bgcolor="#000000"
wmode="direct"
flashvars="liveUrl=localhost://test/data.xml"/>
</BODY>
So it seems to be if a swf file is loaded locally on the machine it lacks the permission to read other local files or it could be something else, what am I missing here? Here are the options I have set on the browser.
EO.WebEngine.BrowserOptions options = new EO.WebEngine.BrowserOptions();
options.AllowJavaScript = true;
options.EnableWebSecurity = false;
options.LoadImages = true;
options.AllowPlugins = true;
options.AllowJavaScriptOpenWindow = true;
options.EnableXSSAuditor = false;
EO.WebEngine.EngineOptions.Default.SetDefaultBrowserOptions(options);
Any help or suggestions would be greatly appreciated.

Hi,
I don't think this has anything to do with the browser engine ---- anything occurs inside the swf file is handled by the Adobe Flash Plugin. As such the related permission settings would be on the Flash plugin side, not on the browser engine side.
Thanks!

Ouch, that is what I feared. If I have a flash.dll of my own, and I choose to use
EO.WebBrowser.Runtime.AdditionalPluginsDirs = new string[] { "c:\\plugins" };
The documentation says I have to include the dll and a "manifest.json", what is this file exactly?

Hi,
This is a file that is needed for Chromium to properly load the plugin. You can find this file in Flash's installation folder (the same folder you get your flash DLL).
Thanks!

I figured out the issue so I thought I'd post about it. Starting from Adobe Flash Player version 23 local file access was disabled on swf files. More details here: https://forums.adobe.com/thread/2210842The solution was to install an older version of the Adobe Flash Player pre-version 23 that was PPAPI.
