Frage

Ich debugge Silverlight 2 auf Firefox. Ich bekomme einen unberechtigten Fehler in Firebug: 

Unhandled Error in Silverlight 2 Application
Catastrophic failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED))
at MS.Internal.XcpImports.CheckHResult(UInt32 hr)

Punkte auf Silverlight.js Linie 26, was ist

control = new ActiveXObject('AgControl.AgControl');

Mein HTML ist

<head>
<script src="Scripts/jquery-1.3.2.min.js" type="text/javascript"></script>

<script type="text/javascript" src="/Silverlight.js"></script>

<script type="text/javascript">
    function onSilverlightError(sender, args) {

        var appSource = "";
        if (sender != null && sender != 0) {
            appSource = sender.getHost().Source;
        }
        var errorType = args.ErrorType;
        var iErrorCode = args.ErrorCode;

        var errMsg = "Unhandled j Error in Silverlight 2 Application " + appSource + "\n";

        errMsg += "Code: " + iErrorCode + "    \n";
        errMsg += "Category: " + errorType + "       \n";
        errMsg += "Message: " + args.ErrorMessage + "     \n";

        if (errorType == "ParserError") {
            errMsg += "File: " + args.xamlFile + "     \n";
            errMsg += "Line: " + args.lineNumber + "     \n";

        }
        else if (errorType == "RuntimeError") {
            if (args.lineNumber != 0) {
                errMsg += "Line: " + args.lineNumber + "     \n";
                errMsg += "Position: " + args.charPosition + "     \n";
            }
            errMsg += "MethodName: " + args.methodName + "     \n";
        }

        $("#errorLocation").html(errMsg);
    }
</script>

Warum wird es nicht in JS gehandhabt und in Fehlerlokation angezeigt?
Tut mir auch leid, dass mein Formatieren ist scheiße.

War es hilfreich?

Lösung

Kam mit einer Lösung
Ging zur Datei app.xaml.cs und überarbeitete die Funktion "Unriandled_Exception"

Damit und ein bisschen Call This JS war es einfach

private void Application_UnhandledException(object sender, ApplicationUnhandledExceptionEventArgs e)
    {
        // If the app is running outside of the debugger then report the exception using
        // the browser's exception mechanism. On IE this will display it a yellow alert 
        // icon in the status bar and Firefox will display a script error.


        // NOTE: This will allow the application to continue running after an exception has been thrown
        // but not handled. 
        // For production applications this error handling should be replaced with something that will 
        // report the error to the website and stop the application.
        e.Handled = true;

        try
        {
            ThrowRightError(e.ExceptionObject);
            //System.Windows.Browser.HtmlPage.Window.Eval("throw new Error(\"Unhandled Error in Silverlight  a 2 Application " + errorMsg + "\");");
        }
        catch
        {
        }

    }
    private void ReportErrorToDOM(ApplicationUnhandledExceptionEventArgs e)
    {
        try
        {
            ThrowRightError(e.ExceptionObject);
            //System.Windows.Browser.HtmlPage.Window.Eval("throw new Error(\"Unhandled Error in Silverlight 2 Application " + errorMsg + "\");");
        }
        catch (Exception)
        {
        }
    }

    private void ThrowRightError(Exception e)
    {
        string errorMsg = "";
        var exLayer = -1;
        //errorMsg += String.Format("<br>Layer {0}<hr>", exLayer);
        Exception ex2 = e;
        while (ex2 != null)
        {
            errorMsg += "Message : <br />" + ex2.Message + "<br />Data :<br />" + ex2.Data + "<br />StackTrace :<br />" + ex2.StackTrace;
            exLayer++;
            errorMsg += String.Format("<br>Layer {0}<hr>", exLayer);
            ex2 = ex2.InnerException;
        }
        errorMsg = errorMsg.Replace('"', '\'').Replace("\r\n", @"<br />");

        HtmlPage.Window.CreateInstance("foo2", new[] { errorMsg });
    }

dann für die JS

function foo2(theAlert) {
     $("#errorLocation").html(theAlert);
}

Ich habe auch herausgefunden, was der ursprüngliche Fehler war

ClientIdTextBlock.SetBinding(TextBox.TextProperty, ClientIdBinding);

Eine Textbox -Bindung für einen TextBlock...dummer Fehler.
