Uploaded Silverlight sample for VBScript.net compiler

dotneteer — Wed, 04 Nov 2009 05:00:00 GMT

I have uploaded Silverlight sample that uses my VBScript.net compiler to http://www.codeplex.com/aspclassiccompiler. It is available under the source tag in change set 31328 or later.

I am not quite using the capabilities in Microsoft.Scripting.Silverlight yet. I want to take advantages of it when its document becomes available. For the time being, I created my own little host called VBScriptHost in the SilverlightApplication1 project.

I modified App.xaml.cs to create an instance of VBScriptHost and expose it. In MainPage.xaml.cs, I created a ScriptScope object. This is the object that I feed host variables to VBScript. I then parse this object to the Execute method of a CompiledCode object.

In the example, I passed MainPage itself with the variable name "page" to the VBScript. In order to expose the object hierachy of the MainPage, I have to expose MyButton using the x:FieldModifier="public" attribute; otherwise, it is an internal property and is hidden from the dynamic code. In future versions, I will modify my binder in an attempt to access the internal properties so that we do not have to change the access level of objects in the page.

As web programmers, we use a lot of strings to move data around the web. Often we’ll use a string to represent a date or an integer or a boolean. Basically "1" in instead of 1, or "April 1, 2009" rather than a proper ISO-8601 formatted culture-invariant date. While these strings are flying around via HTTP it's not a huge deal, but sometimes this loose, even sloppy, use of strings can leak into our own code. We might find ourselves leaving the data times as strings longer and longer, or not even bothering to convert them to their proper type at all. This problem is made worse by the proliferation of JSON, and schema-less/namespace-less XML (that I've often called " angle-bracket delimited files " as they're...(read more)

Microsoft Silverlight 2.0 Wish List

interactive — Thu, 20 Dec 2007 05:00:00 GMT

Well, the year 2007 is nearly at the end and I have my short wish list for Microsoft Silverlight. The following (maybe not complete) unsorted list would be nice to see in 2008 with the next CTP or final version:

When building Silverlight 2.0 Web applications I must be able to consume services (REST, Web Service,...) from cross-domain locations. There are several ideas on how to restrict or allow those access as it should not be possible to access every domain because of security reasons. There are different ideas on how to specify the allowed domains: one could be a file in the root folder of the domain to access where the origin domain must be specified. A configuration on the local Silverlight plug-in would not be very good as applications will not work correctly.
Windows Mobile UI options with the Compact Framework are very dire, without doing some workarounds like writing interop code your are not able to write nice looking applications. They look like years old applications. As WPF is not yet available for Windows Mobile (and maybe will never be available there) Silverlight could be the best answer. I had a look at Adobe Flash Lite on my Dell Axim device and I'm very happy to see that the hardware is able to render vector graphics in a very good time. Well, the Dell Axim has a good built-in graphics card which is able to render 3D graphics, when I'm correct. In my opinion it is very easy to create UI applications (like the iPhone) on Windows Mobile devices if there is a framework available like Silverlight.
As WPF is unimportant for me (only because I'm a Web developer) I would like to see Silverlight running standalone applications. Currently I need some JavaScript and HTML to get it running. I created a small host application that is running something similar to the built-in Web server of Visual Studio .NET to have a standalone application running Silverlight.
Better design experience: well, I think that it is still not very easy for a designer to interact with a developer. I don't know the real problem why it is hard to work together. Looking at WPF I feel that there is the same problem. How many WPF applications do you know or use already? And how long does WPF be available?
Most developers that want to use Silverlight stopped playing with the CTP bits because of missing controls. I had some discussions with Silverlight experts which controls they are missing? I think that we should not put the Windows UI controls to Silverlight (like copy'n paste everything). What about the Mac and Linux users? They don't understand the behavior of Windows UI controls. And the same in the other direction, I don't understand the behavior of Mac controls and don't want to learn all different controls. In my eyes Silverlight should have some base controls like a button which is clickable, or a text box where I can enter some text, but should not work Silverlight-like.
Silverlight (and WPF) in my eyes is a very good technology to built touch-screen usable applications (if used as Web applications or not). They are very easy to adapt to the customers corporate design. Maybe we need more hardware support for input controls like the iPhone or Surface is doing.

Well, one of my last wish list Microsoft already changed: the rename from Silverlight 1.1 to Silverlight 2.0. It is not an update for Silverlight 1.0, it is something complete different. I don't know how Microsoft will name the updates or newer versions of Silverlight 1.0 in the future, maybe there will be no new version for it.

Update 12/21/2007: I got a lot of feedback what maybe is missing on my list. Yes, I know that there are more features that are nice to have. Below you will find some more important missing features:

Socket Support: I don't see this in real life because firewalls will block nearly everything by default. But Sockets are interesting if we want to built peer-to-peer applications (online games and maybe streaming from other web users).
What happen if you print an Silverlight application? There are some ideas to render forms to print. Well, I would'n use Silverlight for printing, maybe generating a XPS or PDF document is much easier.
More space in local isolated storage to store documents or any other data. This should be easily made configurable in the Silverlight configuration.
One thing I would like, too: I don't want to see more different Media Players. I think you agree that there is only a very small range of web developers that have video or audio content to deliver. The media support is very good when i.e. looking at HD video streaming with Silverlight. I would like to see real-world applications instead (my greetings to Oliver Scheer).

One comment for the feature wish no. 3 (running standalone Silverlight applications) in my first list: maybe you can compare it with Adobe Flex. You can run the application in a browser or taking a flex application to the desktop. WPF is not working as it is only supported on Windows desktop PCs. I would like to see Silverlight applications on desktop PCs and, the more important, on Windows Mobile devices. I don't want to connect to the Internet always to run a Silverlight application. Does this make sense?

[de] .NET User Group Franken am 5. Juli 2007

interactive — Wed, 13 Jun 2007 04:00:00 GMT

Die .NET User Group Franken trifft sich mal wieder, diesmal in den Räumen der evosoft GmbH (Dank geht an Igor Milovanovic).

Themen

Daniel Zeiss spricht zum Thema ComfortASP.NET, nachdem ich ihm ja die Zeit beim vorletzten Treffen gestohlen hatte, sorry nochmal!
Ich selber werde einen Überblick über Microsoft Silverlight 1.0 und 1.1 geben. In der Ankündigung steht etwas von "Webpräsentations-Technologie". Nun, Silverlight ist nicht nur etwas für die Anzeige, wie auch Tim Sneath in seinem Post Silverligth Isn't Just about Presentation schreibt. Bei dem letzen Treffen hatte ich bereits WPF/E (der alte Codename) gezeigt, deswegen werde ich diesmal etwas mehr die nicht-grafischen Möglichkeiten in Silverlight zeigen.
Außerdem natürlich wie immer allgemeine Diskussionen.

Und zum Schluß gibt's natürlich wie immer wieder eine Buchverlosung.

Hier noch die Adresse von der evosoft GmbH:

New Examples and Tutorials

interactive — Fri, 08 Jun 2007 04:00:00 GMT

During the last days I have added some new tutorials and examples to my list. Dave Campbell sent me a short message that he has already a kind of Silverlight examples collection. Have a look on his list of Silverlight tagged articles he wrote and external Silverlight examples as well.

There is starting a new series of Silverlight JavaScript Tutorial. The first article is about how to add Silverlight to a Web page.

Rob Conery did his Day 2 article about how to create a data-driven control in Silverlight.

Silverlight Features

Tim Sneath writes on his blog about that Silverlight isn't just about presentation and that there are enough that link Silverlight always with user interface developing. Yes, I thought the same already, everybody is thinking about UI. UI with XAML is only a small part of the great features that Silverlight offers.

Brad Abrams posted a new PhotoViewer application which supports great UI features like panning an dzooming effects, but he also added FileUpload and Networking to his example (incl. source code).

Scott Wisniewski from the Visual Basic Team wrotes about the difference between VB 9, VBx and Silverlight.

JavaScript and .NET Arrays in Silverlight

interactive — Fri, 01 Jun 2007 04:00:00 GMT

During my tests with the DLR (Dynamic Language Runtime) in Silverlight 1.1 I came accross several things that didn't work first. Most of them could be fixed by using small workarounds.

Managed JavaScript (compared with IronPython) does not support generics or .NET arrays. Those features require changes or additions to the language syntax, and therefore are not yet implemented. The main focus on the first version of managed JavaScript was to be EcmaScript compatible.

How can I create a byte array?

The simplies way is to create a helper function that will get a JavaScript array as argument and will return a .NET byte array.

function ConvertToByteArray(inputArray)
{
   var list = new System.Collections.ArrayList();
   
   for(var i=0; i<inputArray.length; i++)
      list.Add(inputArray[i]);

   return list.ToArray(System.Byte.UnderlyingSystemType);
}

This helper function can convert a JavaScript array to a byte array to be passed to .NET methods (i.e. IsolatedStorageFile.Write(...)).

In IronPython generics are already supported, so you can use a List of Byte:

from System.Collections.Generic import List
from System import Byte

s = List[Byte]()
s.Add(58)
s.Add(32)

// the byte[] array you get with following line
ba = s.ToArray()

In future releases this will be changed, I hope so, and will be more transparent.
