Can Pixel-shader 3.0 based shader effect be used to render to a RenderTargetBitmap?

Posted By:      Posted Date: October 03, 2010    Points: 0   Category :WPF

Hello -

I have written a custom shader effect using PS 3.0 that is working great on screen, however I need to have the ability to create a 'snap shot' of the control and write it out to disk.  I have been attempting to use RenderTargetBitmap, however the shader is not being applied to the rendering.  In another forum on stack overflow I posted a similar question and was told that PS 3.0 does not have a software fall back.  I would like to hear from the MS community if that indeed is the case.  If it is, can someone out there tell me how to capture a control that has been rendered using a PS 3.0 pixel shader.  It would be best if I were able to render the control off screen rather than attempting to capture an image off of the screen.

I wrote a VERY simple program to test the ability to capture PS 3.0 rendering to a RenderTargetBit map.  the code is below:

Hopefully someone out there has a solution!  Unfortunately I can not fall back to PS 2.0...

Pixel Shader in WPF, are user created shaders run on hardware or in software?

In general, are user made shaders used in WPF, are they run on the video cards hardware? or are they all run in software mode?   I think I read that the default shaders are run in hardware but that user made shaders are not?

Problem with Pixel Shader 3.0 support in WPF SP1.

I've tried custom effects in WPF with .NET 3.5 SP1. It's amazing feature!
But I tried to compile my pixel shader with ps_3_0 profile and then WPF application throws exception.
So, if I have graphics card with support ps_2_0, ps_3_0 and even ps_4_0, can I use pixel shader profile 3_0 or it's impossible today in WPF? If it's impossible - why? and will WPF dev team provide ps_3_0 support in future releases?

I am using a jquery effect that animate bounce effect, i have a line in my javascript pageLoad function $("#UserBrowserInfoDIV").show('bounce'); - the effects run smoothly but what it does is mess up the bolded text in the div. I have try the items inside the div without bolding and it works fine and no render problem but when bolded the text that are bolded is quite messed up, and barely readable.

Please let me know is there anything else i can do i really would like use this effect.

P.S all the effect have the same render problem, and i am using ie8 under compatibility mode.





How to render a checked CheckBox to a RenderTargetBitmap ?


My checkbox is rendered without a check mark.  If I use only one checkbox (instance object) to render then I can get the check mark to show, but I cannot use this solution.  I need be able to render it using the local checkbox.  This checkbox has the Aero theme applied to it by default and this is also a must have for me.  Other themes built-in themes like Royal, and Luna render with a check mark.


<Canvas Name="canvas">

5 GridView Themes Based on Google's Personalized Homepage (igoogle)

One of the silly features I have found that I like about igoogle is how the pages color palette changes depending upon the time of day. So as the day progresses from morning to afternoon to evening the colors on the page change as well. Like I said, I know this is a silly feature, but I like it. And I have asked around a little bit and seems like other people like it to. To get a better idea of how the colors change, here are the background images from a few of the HTML elements.

Get pixel format, raw format, property id list and property items image in VB.net - C#.net.

n this simple article you will learn that how we can get pixel format, raw format, property id list and property items image in VB and C#.net.

Get Pixel Format:

Image consists of pixels to get the format of the pixel we have a property named pixel format. This property returns an enumeration of pixel format. This enumeration tells the pixel format.

To demonstrate make a window application. Drag one button and a picture box on form.

dynamically adding sql server columns based on number of files in fileuploader


I want to create a new table to sql database at runtime.  The column names would be "Name", "Date", "Event".  I would also like to have one more column name "Image" but the problem is that since the amount of images will vary, I want the application to count the amount of files in the Multiple fileuploader and then add a image column to the table for the respected amount of files. 

For example if i am uploading 3 files in the multiple fileuploader, the names should be "Name", "Date", "Event", "Image1", "image2", Image3"

I also would like that table name to be name dynamically from the textbox Name when the user enters the information.


I have the following code to make a new table, but I dont know how to name the fields at runtime like previously asked please help!!!

Unique content within master page based on conditions met


 Hi all-

I would like to present users with unique content based on certain conditions being met as they land on the home page (default.aspx).  The condition logic will be in the VB code behind Page Load event. The content will go in a content placeholder as specificed from the master page. 

However, the content change wouldn't be something small (ie making a panel or label visible or not) but rather it will be different HTML,  Divs and databound gridview content.  The HTML content will be stored in the database.

Can someone point me in the right direction for best practices on how to accomplish this?

Claims-Based Apps: Claims-Based Authorization with WIF


Over the past few years, federated security models and claims-based access control have become increasingly popular. Platform tools in this area have also come a long way. Windows Identity Foundation (WIF) is a rich identity model framework designed for building claims-based applications and services and for supporting active and passive federated security scenarios.
