使用Awesomium从html按钮运行notepad.exe

Question

I've been looking for an example on how to open a process like notepad.exe from a html-element using WPF and Awesomium 1.7.5. 我一直在寻找有关如何使用WPF和Awesomium 1.7.5从html元素中打开类似notepad.exe的进程的示例。 The idea is that clicking a html element triggers a C# method using javascript as far as I understand the Awesomium API. 据我所知，单击html元素会触发使用javascript的C＃方法。 However, all examples I can find refer to an earlier version that now uses obsolete functions... 但是，我可以找到的所有示例均引用了现在使用过时功能的早期版本...

Can anyone please provide me with an example on how to execute C#-code when openNotepad() is triggered? 有人可以给我提供一个示例，说明触发openNotepad（）时如何执行C＃代码吗？

HTML: HTML：

<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
    <meta charset="utf-8" />
    <title></title>  
</head>
<body>
    <button onclick="app.openNotepad()">This button will open Notepad</button>
</body>
</html>

C#: C＃：

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();

        webControl.Source = new Uri("index.html");
    }

    private void webControl_DocumentReady(object sender, DocumentReadyEventArgs e)
    {
        BindMethods(webControl);
    }

    private void BindMethods(IWebView _webView)
    {
        JSValue result = webControl.CreateGlobalJavascriptObject("app");
        if (result.IsObject)
        {
            JSObject appObject = result;
            appObject.Bind("openNotepad", openNotepad);
        }
    }

    private JSValue openNotepad(object obj, JavascriptMethodEventArgs jsMethodArgs)
    {
        Process.Start("notepad.exe");
        return null;
    }
}

According to Awesomium documentation to Bind and JavascriptMethodHandler , methods of handling Javascript events has changed in version 1.7.5. 根据Awesomium Bind和JavascriptMethodHandler的文档，在版本1.7.5中，处理Javascript事件的方法已更改。

JavascriptMethodEventHandler now obsolete, and new Bind overload should be used. JavascriptMethodEventHandler现在已过时，应使用新的Bind重载。

Now your code could look like 现在您的代码可能看起来像

private void BindMethods(IWebView _webView)
{
    JSValue result = webControl.CreateGlobalJavascriptObject("app");
    if (result.IsObject)
    {
        JSObject appObject = result;
        appObject.Bind("openNotepad", openNotepad);
    }
}

private JSValue openNotepad(object obj, JavascriptMethodEventArgs jsMethodArgs)
{
    Process.Start("notepad.exe");
    return null;
}

Note, there is example of using new overload at the end of Bind documentation page. 注意，在绑定文档页面的末尾有使用新的重载的示例。

Also note that javascript method in your sample actually not calling app.openNotepad() method, but alert("Run Notepad"); 另请注意，示例中的javascript方法实际上并未调用app.openNotepad()方法，而是alert("Run Notepad");

WshShell = new ActiveXObject("WScript.Shell"); WshShell = new ActiveXObject（“ WScript.Shell”）;

WshShell.Run("c:/windows/system32/notepad.exe", 1, false); WshShell.Run（“ c：/windows/system32/notepad.exe”，1，否）;
