I use libs from 0.4.0 sdk
http://sdlsdk.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=17839
As I understood It's final Microsift release of Managed JScript.

Yes, but how? Where do I find the JScript binaries. The current DLR package (http://sdlsdk.codeplex.com/) only contains the IronRuby and IronPython languages.

Hey Jonathan.

I thought the Managed JScript for DLR was dropped? How does this work for SL3?

Hi Darrin_ru,

Please replace your code with mine and have a test.

            string script = "lblMessage.Text = 'First line of code';\r\n" + "lblMessage.Text = 'Second line of code';";
            ScriptSource scriptSource = scriptEngine.CreateScriptSourceFromString(script, Microsoft.Scripting.SourceCodeKind.Statements);

It works on Silverlight 3.

Best regards,

Jonathan

Execution JScript in SilverlIght Application using DLR

darrin_ru — Mon, 15 Jun 2009 14:33:46 GMT

Hello!
I try to make scriptable application using Silverleght DLR. When I try execute JScript code witch cotains two or more lines of code, execution only first line. For example:
I had Compiled SL application written on С#. Main page contains Label named "lblMessage" and Button with Click event handler.

private void Button_Click(object sender, RoutedEventArgs e)
{
ScriptRuntime scriptRuntime = ScriptRuntime.Create();
foreach (string name in new string[] { "mscorlib", "System", "System.Windows", "System.Windows.Browser", "System.Net" })
{
scriptRuntime.LoadAssembly(scriptRuntime.Host.PlatformAdaptationLayer.LoadAssembly(name));
}
ScriptEngine scriptEngine = scriptRuntime.GetEngine("js");
ScriptScope baseScope = scriptEngine.CreateScope();
gsFormManager fm = gsApplicationManager.FormManager;
baseScope.SetVariable("lblMessage", lblMessage);
string script = "lblMessage.Text = 'First line of code';\r\n" + "lblMessage.Text = 'Second line of code'";
ScriptSource scriptSource = scriptEngine.CreateScriptSourceFromString(script);
CompiledCode compiledCode = scriptSource.Compile();
compiledCode.Execute(baseScope);
}

After execution Label.Text will be equal "First line of code" string.

Why ignored second line of code ?

Thank you.
