CefSharp3 AddWebPluginPath doesn't seem to work

[Michal Tsadok]

CefSharp3 code fails to set the plugin path

On a machine without Flash player installed, I'm getting Couldn't load plug-in. when trying to load flash content

This is the code that I've added 
[I took CefSharp3 from NuGet on April 27th 2015]
            Cef.AddWebPluginPath(Path.Combine(Directory.GetCurrentDirectory(), "NPSWF32_13_0_0_214.dll")); // Flash 13.0.0.214
            Cef.AddWebPluginPath(Path.Combine(Directory.GetCurrentDirectory(), "np-mswmp(1_0_0_8).dll")); // Windows Media Player 1.0.0.8
            Cef.RefreshWebPlugins();
[I also tried this relative path - @"./NPSWF32_13_0_0_214.dll" but no success]

I followed these guidelines

This code worked on CefSharp1
            var settings = new CefSharp.Settings();
            settings.AddPluginPath(@"./NPSWF32_13_0_0_214.dll"); // Flash 13.0.0.214
            settings.AddPluginPath(@"./np-mswmp(1_0_0_8).dll"); // Windows Media Player 1.0.0.8
            CEF.Initialize(settings);

Please advise

Thanks!

You'll need to call those methods in the new Cef.OnContextInitialized delegate.

An example
https://github.com/cefsharp/CefSharp/blob/master/CefSharp.Example/CefExample.cs#L79

This is relatively new and will be included as part of the upcoming `39.0.1` release

Could you please provide a clear code example?

I can't get it working.

Nope, no sample exists. Never used this feature. We're in uncharted territory.

What does your code look like?

Alex,

Thanks!!

When 39.0.1 is planned to be released?

Hi Michal,

I see it's been tagged 13 hours ago - https://github.com/cefsharp/CefSharp/releases/tag/v39.0.1

The binaries/NuGet have not been pushed to NuGet.org yet as far as I can tell. Until that happens you can grab them from the CI build at https://www.myget.org/gallery/cefsharp

            Cef.OnContextInitialized = delegate
            {
                Cef.AddWebPluginPath(@"C:\Windows\System32\Macromed\Flash\Flash.ocx");
                Cef.AddWebPluginPath(@"C:\Program Files\Microsoft Silverlight\5.1.30514.0\npctrl.dll");
                Cef.SetCookiePath("cookies", true);
            };
            Cef.RefreshWebPlugins();

Cef.RefreshWebPlugins() should be called after the two calls to `Cef.AddWebPluginPath()`

[Alex Maitland]

The packages just need a few more eyes over them before being pushed to Nuget.org

Hopefully in the next day or two if all goes well.

Thanks to all of you

I'll wait for the NuGet package and put the RefreshWebPlugin within the OnContextInitialized 

Cheers

[Michal Tsadok]

Works!!!

Thanks :)

[Alex Maitland]

Great. Thanks for reporting back.

I'll add the code as an example, was this what you ended up with?

Cef.OnContextInitialized = delegate
{
  Cef.AddWebPluginPath(@"C:\Windows\System32\Macromed\Flash\Flash.ocx");
  Cef.AddWebPluginPath(@"C:\Program Files\Microsoft Silverlight\5.1.30514.0\npctrl.dll");


  Cef.RefreshWebPlugins();
};

Somehow I can't get this working correctly. 

Silverlight is not rendering. It is loading though.

I am not sure about Flash or Java.

But it should be the correct way to do it.

Silverlight in `WPF`? There's a known problem https://github.com/cefsharp/CefSharp/issues/467
