Silverlight Simple Animation

Silverlight has several built in techniques for animating controls. Many of these technologies are particularly useful for creating simple animations meant to decorate a web page with eye catching movement that draws the reader's attention. In this post I will skip over these decorative technologies, and instead show how to create a simple animation using a technique similar to those used in many games.

Animation Extender ( LinkButton Disbale )


My flyout animation starts on a click of linkbutton, everything works fine on IE, as I click the linkbutton flyout animation is triggered and linkbutton gets disbaled during the animation. But on Firefox and Chorme linkbutton doesn't get disbaled , due which if I again and again click on the linkbutton the flyout animation keeps moving towards left side on every click.

In firefox and chorme linkbutton always remains enabled.

 <cc1:AnimationExtender ID="AnimationExtender1" TargetControlID="lnkBtnAbt" runat="server">
                        <EnableAction Enabled="false" />
                        <StyleAction AnimationTarget="moveMe" Attribute="display" Value="block"/>
                        <Parallel AnimationTarget="moveMe" Duration=".5" Fps="30">
                            <Move Horizontal="-350" Vertical="50"></Move>
                            <FadeIn Duration=".5"/>
                        <Parallel AnimationTarget="moveMe" Duration=".5">

ToggleDebugCompilation fails trying to perform "an unauthorised operation"



We're having a problem with the Visual Studio 2008 RTW version of the web deployment projects on a colleagues machine. The project works fine if I run it on my machine, but when he tries to run it on his machine he gets:

  Task "Exec"
    if exist ".\TempBuildDir\" rd /s /q ".\TempBuildDir\"
  Done executing task "Exec".

ArrayList.ToArray fails!


In my app, I have code similar to the following:



               ArrayList alStartFrames = new ArrayList();
                byte[] abytTest = { 1, 2 };


                byte[] abytCombinedFrame = (byte[])alStartFrames.ToArray(typeof(byte));

            catch (Exception ex)

The call to ToArray always fails and the exception is caught even though I'm pretty sure alStartFrames is an array list of byte arrays. Anyone have any insight on why this is happening?! TIA

Data Security: Stop SQL Injection Attacks Before They Stop You


To execute a SQL injection attack, a hacker writes a Web page that captures text in a textbox to be used to execute a query against a database. The hacker enters a malformed SQL statement into the textbox that causes the back-end database to perform operations the owners did not intend it to perform, like making unauthorized updates. This article explains how you can protect against the all too common SQL injection attack in your own database. The steps covered include data validation, proper exception handing, and much more.

DirectX 8.0: Enhancing Real-Time Character Animation with Matrix Palette Skinning and Vertex Shaders


DirectX 8.0 allows the creation of smooth and realistic character movements that are more life-like than simple articulated structure animations. This is made possible by its improved support for vertex tweening and blended vertex deformations, also known as soft-skinning. After a brief history of the use of these techniques in DirectX, soft-skinning using the fixed function pipeline is discussed. This is followed by the use of matrix palettes from within vertex shaders to create a customized soft-skinning solution that takes advantage of the benefits of vertex shaders, such as hardware acceleration and custom lighting algorithms without the limitations of fixed-function solutions.

routing fails



I am trying to compile and run an asp.net application and am getting the following errors

 HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

How to stop the repeated database queries for roles


Hello, friends,

We have a web application using VS 2008, c#. We try to filter siteMap nodes based on security roles. We have our customized the mether GetRolesForUser() in RoleProvider class to determine a user's role. In this method, roles will be returned by querying an SQL Server database.

However, we found that each time a page was loaded/refershed, this  GetRolesForUser() was called, and the database would be queried. This is too MUCH and expensive.

We thought the roles should be queried only once when a user logs in. After that, role info should be stored somewhere for this user, rather than query DB all the time.

Any ideas, reference paper, snipet,...,?

Thanks a lot!

Using Infopath form fieldnames in a workflow fails



I designed a form in Infopath and I published it on a SP2007 server to use in a workflow in a library. That goes fine. In the workflow I send an email message. I can use the fields from my Infopath form in the message that I create. 
If the workfow is starts, Shrepoints sends me the message. But it does not use the fields from my InfoPtah form in the message in stead I see questionmarks.

Why doesn't it show the fields?

I alse saw (maybe this makes it clear) that when I let it dipslay the URL in the message, it show: http://1.portal.lucasonderwijs, but the actual site is whithout the "1" and it should also start with https://

Has anyone seen this before?

Thank you,


Crawler fails to register date properties of user profiles with the month of January, April, August


This seems to be a bug when the crawler search the user profiles in MOSS 2007.  When crawled, user profiles with a SPS-HireDate in the months of January, April, August and December will be detected, but a full-text (SQL) search returns those profiles without the HireDate field.

User profiles with HireDates in other months work correctly, returning the HireDate in the search.  And changing the month of a problematic user profile also fixes the problem.

This problem is also reflected in the fact that while we have 499 user profiles using the SPS-HireDate property,  the managed property page from the search section only has 350 items with the HireDate property.

We're running MOSS 2007 32bit with SP2 with an English language base and the Spanish language pack. I'd considered date format problems, but I can't imagine how some months would work, while others wouldn't.

Any ideas?

Javascript fails in chrome and firefox, works fine in IE



I am customizing Newform.aspx i.e. hiding some fields, making other readonly etc. It works fine in IE but fails miserably in chrome and firefox i.e. readonly are no more readonly, hidden are no more hidden. Here is my code:

    ctrl.value = properParam;
    var ctrl = findacontrol("RefReqOpptyId");
    var param = getURLParam('OpptyId');   
    var properParam = replaceCharacters(param);
    ctrl.value = properParam;

    param = getURLParam('RefFromAE');
    properParam = replaceCharacters(param);
    setPeoplePicker("People Picker", properParam);

DateTime custom managed property search fails with " Your query is malformed. Please rephrase your q

I've created a front end search page in Silverlight 4 for SharePoint Search.  Currently we are using WSS 3.0 + Search Server Express 2008 (v  The page interacts with the MOSS version of the search web service at:   <site collection>/_vti_bin/search.asmx The reason for this approach is the unique way the requirements specify the look and behavior of the results.  The built-in Search Center page or web parts will not satisfy these requirements. We are going into production but I still cannot figure out how to search against my custom managed properties that are of Type DateTime.  If I cannot get this to work, it is a showstopper. I've tried numerous variations on the SQL Syntax and cannot get it to work.  I know the error is in the date portion of the WHERE clause since I can remove it and searches work fine.
