C＃Webbrowsercontrol with ProxyとJavascriptからC＃への呼び出し

webbrowsercontrol ObjectForScripting (source)の機能を組み合わせて、javascriptのC＃関数とそのWebブラウザコントロールのプロキシ(source)を呼び出しました。C＃Webbrowsercontrol with ProxyとJavascriptからC＃への呼び出し

各機能はそれぞれ独自の機能を備えています。しかし、私はそれらを組み合わせると、javascriptからの呼び出しはもう働かない。 ErrorMessageは、例えば、ソースコード「テスト」

オブジェクトがプロパティまたはメソッドをサポートしない

底部にあります。コメントと私は問題がインタフェースIServiceProviderから関数QueryServiceだと思いForm1_Load

// Comment this block for Callback working 
object obj = webBrowser1.ActiveXInstance; 
IOleObject oc = obj as IOleObject; 
oc.SetClientSite(Proxy as IOleClientSite);

あなたは、両方の機能を試すことができます。私はScriptmanagerからのGUIDでそれをピン止めしようとしましたが、解決策は見つかりませんでした。

webBrowser1.ObjectForScriptingは、クライアントサイトを置き換えるため、効果がありません。 WinFormsの既定のクライアントサイトでは、IDocHostUIHandler :: GetExternalが実装され、ObjectForScriptingの値が返されます。 Proxyクラスでも同じことができます。

ありがとうございました。私はそれがほとんど働いている。私はポストの現在の問題について説明しました。私は、MessageBoxが表示された後、InvalidVariant例外が発生しました。別のヒントはありますか？ –

どの行が例外をスローしますか？いくつかのメソッドのシグネチャは、refの代わりに使うべきです。 INET_E_DEFAULT_ACTIONを返すか、COMメソッドを無効にして何もしない（S_OKに変換する）のではなく、NotImplementedException（E_NOTIMPLに変換）をスローする –

+0

例外は 'Application.Run（new Form1（））; 'Program.cs'にあります。だから私は機能が間違っているという手がかりがないのです。私は 'IDocHostUIHandler'の定義が異なっていました。定義のための信頼できる情報源はありますか？ –
