HtmlPage.Window.Invoke does not appear to work in VB

05-05-2008 6:59 AM |

i am thinking there is a problem with the HtmlPage.Window.Invoke in VB

what works in C#, gets the following

An exception of type 'System.InvalidOperationException' occurred in System.Windows.Browser.dll but was not handled in user code

Additional information: [ScriptObject_InvokeFailed]
Arguments:
Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=8.0.30226.2&File=System.Windows.Browser.dll&Key=ScriptObject_InvokeFailed

Hello,

I just tested it. It's working for me.

Example:

Imports System.Windows.Browser

Partial Public Class Page
    Inherits UserControl

    Public Sub New()
        InitializeComponent()
        AddHandler MouseLeftButtonDown, AddressOf Click
    End Sub
    Public Sub Click(ByVal sender As Object, ByVal e As MouseButtonEventArgs)
        HtmlPage.Window.Eval("window.close();")
    End Sub
End Class

Hope it helps.

Agreed - the eval works - the invoke, which goes back to the Javascript isn't

Can you show me your code? It's working fine for me.

It works for me. I tested with both HTML page or aspx page.

Example:

<head runat="server">

    <script type="text/javascript">
     function onCloseWindow(){
       window.close();
     }

</head>
<body style="height:100%;margin:0;">
    <form id="form1" runat="server" style="height:100%;">

I showed you both aspx and HTML in my previous post. "SilverlightApplication1VBTestPage.html (HTML Version) "

GeordieJenner:

IMHO, I never like that idea... In fact, it is IE-only solution. I used to open a lot of tabs in my browsers and I never want any website to close my browser... I'm not sure why you want to do that.

Okay. But we are discussing about the fact whether HtmlPage.Window.Invoke is working fine in VB or not.

Have you tested my code in my previous message? Is it working for you?
