New message in Outlook using Silverlight 4 and AutomationFactory

29 Mar

Silverlight 4 makes it possible to use the AutomationFactory (COM) to communicate with applications installed on the client computer.

To use the AutomationFactory it’s required that the application runs as an out-of-browser application with elevated trust. Furthermore it’s required that the user  can use the COM (the client must run on a Windows computer for COM to work – Microsoft have stated they are looking into getting COM+ support working in Silverlight 4 RTM on a Mac).


In the sample above I first of all check that the user is running the application with elevated trust and that the AutomatationFactory is available. I create a new dynamic object as an instance of Outlook and a new mail object. I set the To, Subject and Body on the mail object, saves it and finally sends it.

ScriptNotify in Silverlight 4

29 Mar

Silverlight 4 introduces a WebBrowser control which I have written a short post about this control here.

In some scenarios it is necessary to get a response from the WebBrowser control – to do that you can use the ScriptNotify event on the WebBrowser control. The ScriptNotify occurs when the content contained in the WebBrowser control passes a string to the Silverlight plug-in by using JavaScript.

To demonstrate the functionality of ScriptNotify event, I have created a Silverlight 4 project and an ASP.NET webproject that hosts the Silverlight project. I have made the Silverlight project an out-of-browser application – this is necessary to display HTML in the WebBrowser.

On the server-side I have added an HTML-file called HTMLPage1.htm that will be the HTML-file that I displays in the WebBrowser. I have added a button to the page and added a JavaScript function called notify that is invoked when I click the button.


In the Silverlight project I have added a WebBrowser control on the MainPage.xaml and I have set the source to our HTML-page on the server.


In the code-behind I subscript to the WebBrowser’s ScriptNotify event and implement an EventHandler.


To invoke the ScriptNotify event from the HTML-file I need to pass a string to the Silverlight plug-in. The Silverlight hosting environment allows you to call Notify on the Window.external object and pass a string to the plug-in. When you do this, the ScriptNotify event occurs.


My ScriptNotify event catches the call from the JavaScript function and from the NotifyEventArgs in the EventHandler I get the string value sent from the JavaScript function.
