c# ActiveX 与 js交互

Question

    Type typeIOleObject = this.GetType().GetInterface("IOleObject", true);
                object oleClientSite = typeIOleObject.InvokeMember("GetClientSite",                    
                 BindingFlags.Instance | BindingFlags.InvokeMethod | BindingFlags.Public,
                null,
                this,
                null);
                                if (oleClientSite == null)
                {
                    MessageBox.Show("为null");
                    return;
                }                IOleClientSite oleClientSite2 = oleClientSite as IOleClientSite;
                IOleContainer pObj;
                oleClientSite2.GetContainer(out pObj);上面是代码 object oleClientSite = typeIOleObject.InvokeMember("GetClientSite",                    
                 BindingFlags.Instance | BindingFlags.InvokeMethod | BindingFlags.Public,
                null,
                this,
                null);这里取的  oleClientSite  为空，取不到。不知道什么问题.
如果别人有好的  ActiveX 与  js交互的代码也可以帖上来 谢谢

Answer 1

之前做过的一个activeX控件操纵USBKEY的程序
activeX控件是用C++写的！.net activeX的编写方法网上有，自己baidu吧<OBJECT ID="UsbKey" CLASSID="CLSID:项目里的东西，这里就不写了">
</OBJECT><script language="javascript" type="text/javascript">
    var lock;
    var lockmsg;
    var isinstall;
    function DetectActiveX() {
        lock = document.getElementById("lock");
        lockmsg = document.getElementById("usbkey_Status");
        document.getElementById("usbcode").value = "";
        try {
            var comActiveX = new ActiveXObject("TestUSBKey.USBKey.1");
            lock.style.background = "url(images/yellow.png) 50% 0 no-repeat";
            lockmsg.innerHTML = "<font color='orange'>请插入USBKey</font>";
            document.getElementById("login_form_Usbkey").style.display = "none";
            isinstall = true;
            getinfo();
        }
        catch (e) {
            isinstall = false;
            lock.style.background = "url(images/red.png) 50% 0 no-repeat";
            lockmsg.innerHTML = "<font color='red'>安全控件未安装，请下载安装</font>";
            document.getElementById("login_form_Usbkey").style.display = "";
        }
        function getinfo() {
        var data = UsbKey.GetContent();//这里是activeX控件里的函数，返回一个string
        if (data != "" && data != "undefined" && data != null) {
            lock.style.background = "url(images/green.png) 50% 0 no-repeat";
            lockmsg.innerHTML = "<font color='green'>USBKey已插入，请输入帐号密码登录</font>";
            document.getElementById("usbcode").value = data;
        } else {
        lock.style.background = "url(images/yellow.png) 50% 0 no-repeat";
        lockmsg.innerHTML = "<font color='orange'>请插入USBKey</font>";
        }    }    }
    </script>

Answer 2

c# ActiveX 与 js交互
还没用过啊，从哪里开始学这些东西啊。

Answer 3

to guoyun911谢谢你的代码，但我仔细看了一下你的代码，是  js  操作ocx 控件的。麻烦请看清我的需要。
要js  调用  ocx  的函数，然后  ocx  的函数要回调  js 函数。谢谢

JavaScript调用ActiveX想必大家都很熟悉，这里就不说了。主要说说ActiveX怎么调用JavaScript吧。首先把http://269181927.iteye.com/blog/1045372这篇文章中创建好的修改代码。第一步创建接口[ComImport,Guid("00000118-0000-0000-C000-000000000046"),
InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
public interface IOleClientSite
{
    void SaveObject();
    void GetMoniker(uint dwAssign,uint dwWhichMoniker,object ppmk);
    void GetContainer(out IOleContainer ppContainer);
    void ShowObject();
    void OnShowWindow(bool fShow);
    void RequestNewObjectLayout();
}[ComImport,Guid("0000011B-0000-0000-C000-000000000046"),
InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]
public interface IOleContainer
{
    void EnumObjects([In,MarshalAs(UnmanagedType.U4)]int grfFlags,
        [Out,MarshalAs(UnmanagedType.LPArray)]object[]ppenum);
 
    void ParseDisplayName([In,MarshalAs(UnmanagedType.Interface)]object pbc,
        [In,MarshalAs(UnmanagedType.BStr)]string pszDisplayName,
        [Out,MarshalAs(UnmanagedType.LPArray)]int[]pchEaten,
        [Out,MarshalAs(UnmanagedType.LPArray)]object[]ppmkOut);
 
    void LockContainer([In,MarshalAs(UnmanagedType.I4)]int fLock);
} 在控件类中添加方法：private void btReaset_Click(object sender, EventArgs e)
{
   // WebBrowser wb = new WebBrowser();
    //wb.Document.InvokeScript("say", new string[] { "你好！" });
    CallJavaScript("say('你好！')");
}
 
private void CallJavaScript(string code)
{
    Type typeIOleObject = this.GetType().GetInterface("IOleObject", true);
    object oleClientSite = typeIOleObject.InvokeMember("GetClientSite",
    BindingFlags.Instance | BindingFlags.InvokeMethod | BindingFlags.Public,
    null,
    this,
    null);
 
    IOleClientSite oleClientSite2 = oleClientSite as IOleClientSite;
    IOleContainer pObj;
    oleClientSite2.GetContainer(out pObj);
 
    //获取页面的Script集合
    IHTMLDocument2 pDoc2 = (IHTMLDocument2)pObj;
    IHTMLWindow2 win2 = (IHTMLWindow2)pDoc2.parentWindow;
 
    win2.execScript(code, "javascript");
    //object script = pDoc2.Script;
 
    //try
    //{
    //    script.GetType().InvokeMember(functionName,
    //    BindingFlags.Instance | BindingFlags.InvokeMethod | BindingFlags.Public,
    //    null,
    //    script,
    //    args);
    //}
    //catch { }
}
   在页面上添加JavaScript方法function say(msg) {
    alert(msg);
}
