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">

JQGrid Loading deleted values



This is quite strange. here is the issue:

Some Info:

1. I'm using a multi-select jqgrid.

2. I have my own delete button to delete multiple orders

The problem:

When i press the delete button on the pager of my jqgrid, the records are deleted from the database but JqGrid shows some records (4-5). On refreshing the grid, correct numbers of records are shown.

Here is the code:

function delorder() {
        var amg = $("#horder").getGridParam('selarrrow');
        var cont = amg.length;
        if (amg.length > 0) {

On page loading or executing all CSS flags are ignored and website is plain without formatting


 My problem is whenever i execute my app the first page that loads is the login page pointed to by my web.config file forms authentication, this page is meant to show CSS formatting for the info i am displaying but it is not. Any help with this problem would be great. A cut and paste of my problem is shown below as you can see there is no CSS.

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.

Prevent loading big images ..



i need to prevent loading big images e.g max 100KB

but i only store url

1. user put url with image (i remember this string in database not image itself)

this cause that i can not check image size before store url in database

because user can store url and after this operation put bigger file at that location)

2. my web page generate some different image based on first image

and i need to load portion of image 

to stream and set buffer size to 100KB + 1 Byte

if stream is larger than 100KB that user put bigger file 

how can i accomplish that?

FileStream can not use URI as location only disc location

what should i use instead?

please help,

asynchronous loading user controls


I have 3 user controls that I have to load at the same time.  They each contain a gridview that pulls data from the database.  They are doing a "delay" load of the data so there is a progress bar template that shows that the data is loading however the first gridview fires and loads, then the second, then the third and I need them to all fire at the same time.  Any ideas? 

Debugger not loading properly and exiting


I am attempting to debug my Visual Studio 2005 project. I have Internet explorer 8 and it's running on IIS.

When I hit the "debug" button, a new Internet Explorer browser window opens and my ASP VB .NET application loads normally. However, Visual studio returns back to regular editting mode and I can hit the "debug" button again. No break points hit but my web page still runs and loads normally.

The Output screen use to show Web.Server(exit 0) but now it doesn't show anything.

Any help would be greatly appreciated, I've been trying to find a solution for a while...


InfoPath Workflow Task Form "Loading" event handler only being called after App Pool recycled.


I have a Workflow that is using an InfoPath task form.  In the "FormEvents_Loading" method event handler I have some code that needs to run each time the form is opened.   I recycle the App Pool and open the form the code runs perfectly, but if I close and try to re-open the form the code is not run at all.  I can then recycle the App Pool again and on the next load the code executes just fine.   The code that is supposed to be run is a very simple statement to set a field value, so I don't think it is interfering.

Does anyone know what this might be?
