• Creating Item Templates as Visual Studio 2010 Extensions

  - by maziar

  Technorati Tags: Visual Studio 2010 Extension,T4 Template,VSIX,Item Template Wizard This blog post briefly introduces creation of an item template as a Visual studio 2010 extension. Problem specification Assume you are writing a Framework for data-oriented applications and you decide to include all your application messages in a SQL server database table. After creating the table, your create a class in your framework for getting messages with a string key specified.   var message = FrameworkMessages.Get("ChangesSavedSuccess");   Everyone would say this code is so error prone, because message keys are not strong-typed, and might create errors in application that are not caught in tests. So we think of a way to make it strong-typed, i.e. create a class to use it like this:   var message = Messages.ChangesSavedSuccess; in Messages class the code looks like this: public string ChangesSavedSuccess {     get { return FrameworkMessages.Get("ChangesSavedSuccess"); } }   And clearly, we are not going to create the Messages class manually; we need a class generator for it.   Again assume that the application(s) that intend to use our framework, contain multiple sub-systems. So each sub-system need to have it’s own strong-typed message class that call FrameworkMessages.Get method. So we would like to make our code generator an Item Template so that each developer would easily add the item to his project and no other works would be necessary.   Solution We create a T4 Text Template to generate our strong typed class from database. Then create a Visual Studio Item Template with this generator and publish it.   What Are T4 Templates You might be already familiar with T4 templates. If it’s so, you can skip this section. T4 Text Template is a fine Visual Studio file type (.tt) that generates output text. This file is a mixture of text blocks and code logic (in C# or VB). For example, you can generate HTML files, C# classes, Resource files and etc with use of a T4 template.   Syntax highlighting In Visual Studio 2010 a T4 Template by default will no be syntax highlighted and no auto-complete is supported for it. But there is a fine visual studio extension named ‘Visual T4’ which can be downloaded free from VisualStudioGallery. This tool offers IntelliSense, syntax coloring, validation, transformation preview and more for T4 templates.     How Item Templates work in Visual Studio Visual studio extensions allow us to add some functionalities to visual studio. In our case we need to create a .vsix file that adds a template to visual studio item templates. Item templates are zip files containing the template file and a meta-data file with .vstemplate extension. This .vstemplate file is an XML file that provides some information about the template. A .vsix file also is a zip file (renamed to .vsix) that are open with visual studio extension installer. (Re-installing a vsix file requires that old one to be uninstalled from VS: Tools > Extension Manager.) Installing a vsix will need Visual Studio to be closed and re-opened to take effect. Visual studio extension installer will easily find the item template’s zip file and copy it to visual studio’s template items folder. You can find other visual studio templates in [<VS Install Path>\Common7\IDE\ItemTemplates] and you can edit them; but be very careful with VS default templates.   How Can I Create a VSIX file 1. Visual Studio SDK depending on your Visual Studio’s version, you need to download Microsoft Visual Studio SDK. Note that if you have VS 2010 SP1, you will need to download and install VS 2010 SP1 SDK; VS 2010 SDK will not be installed (unless you change registry value that indicated your service pack number). Here is the link for VS 2010 SP1 SDK. After downloading, Run it and follow the wizard to complete the installation.   2. Create the file you want to make it an Item Template Create a project (or use an existing one) and add you file, edit it to make it work fine.   Back to our own problem, we need to create a T4 (.tt) template. VS-Prok: Add > New Item > General > Text Template Type a file name, ex. Message.tt, and press Add. Create the T4 template file (in this blog I do not intend to include T4 syntaxes so I just write down the code which is clear enough for you to understand)   <#@ template debug="false" hostspecific="true" language="C#" #> <#@ output extension=".cs" #> <#@ Assembly Name="System.Data" #> <#@ Import Namespace="System.Data.SqlClient" #> <#@ Import Namespace="System.Text" #> <#@ Import Namespace="System.IO" #> <#     var connectionString = "server=Maziar-PC; Database=MyDatabase; Integrated Security=True";     var systemName = "Sys1";     var builder = new StringBuilder();     using (var connection = new SqlConnection(connectionString))     {         connection.Open();         var command = connection.CreateCommand();         command.CommandText = string.Format("SELECT [Key] FROM [Message] WHERE System = '{0}'", systemName);         var reader = command.ExecuteReader();         while (reader.Read())         {             builder.AppendFormat("        public static string {0} {{ get {{ return FrameworkMessages.Get(\"{0}\"); }} }}\r\n", reader[0]);         }     } #> namespace <#= System.Runtime.Remoting.Messaging.CallContext.LogicalGetData("NamespaceHint") #> {     public static class <#= Path.GetFileNameWithoutExtension(Host.TemplateFile) #>     { <#= builder.ToString() #>     } } As you can see the T4 template connects to a database, reads message keys and generates a class. Here is the output: namespace MyProject.MyFolder {     public static class Messages     {         public static string ChangesSavedSuccess { get { return FrameworkMessages.Get("ChangesSavedSuccess"); } }         public static string ErrorSavingChanges { get { return FrameworkMessages.Get("ErrorSavingChanges"); } }     } }   The output looks fine but there is one problem. The connectionString and systemName are hard coded. so how can I create an flexible item template? One of features of item templates in visual studio is that you can create a designer wizard for your item template, so I can get connection information and system name there. now lets go on creating the vsix file.   3. Create Template In visual studio click on File > Export Template a wizard will show up. if first step click on Item Template on in the combo box select the project that contains Messages.tt. click next. Select Messages.tt from list in second step. click next. In the third step, you should choose References. For this template, System and System.Data are needed so choose them. click next. write down template name, description, if you like add a .ico file as the icon file and also preview image. Uncheck automatically add the templare … . Copy the output location in clip board. click finish.     4. Create VSIX Project In VS, Click File > New > Project > Extensibility > VSIX Project Type a name, ex. FrameworkMessages, Location, etc. The project will include a .vsixmanifest file. Fill in fields like Author, Product Name, Description, etc.   In Content section, click on Add Content. choose content type as Item Template. choose source as file. remember you have the template file address in clipboard? now paste it in front of file. click OK.     5. Build VSIX Project That’s it, build the project and go to output directory. You see a .vsix file. you can run it now. After restarting VS, if you click on a project > Add > New Item, you will see your item in list and you can add it. When you add this item to a project, if it has not references to System and System.Data they will be added. but the problem mentioned in step 2 is seen now.     6. Create Design Wizard for your Item Template Create a project i.e. Windows Application named ‘Framework.Messages.Design’, but better change its output type to Class Library. Add References to Microsoft.VisualStudio.TemplateWizardInterface and envdte Add a class Named MessagesDesigner in your project and Implement IWizard interface in it. This is what you should write: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.VisualStudio.TemplateWizard; using EnvDTE; namespace Framework.Messages.Design {     class MessageDesigner : IWizard     {         private bool CanAddProjectItem;         public void RunStarted(object automationObject, Dictionary<string, string> replacementsDictionary, WizardRunKind runKind, object[] customParams)         {             // Prompt user for Connection String and System Name in a Windows form (ShowDialog) here             // (try to provide good interface)             // if user clicks on cancel of your windows form return;             string connectionString = "connection;string"; // Set value from the form             string systemName = "system;name"; // Set value from the form             CanAddProjectItem = true;             replacementsDictionary.Add("$connectionString$", connectionString);             replacementsDictionary.Add("$systemName$", systemName);         }         public bool ShouldAddProjectItem(string filePath)         {             return CanAddProjectItem;         }         public void BeforeOpeningFile(ProjectItem projectItem)         {         }         public void ProjectFinishedGenerating(Project project)         {         }         public void ProjectItemFinishedGenerating(ProjectItem projectItem)         {         }         public void RunFinished()         {         }     } }   before your code runs  replacementsDictionary contains list of default template parameters. After that, two other parameters are added. Now build this project and copy the output assembly to [<VS Install Path>\Common7\IDE] folder.   your designer is ready.     The template that you had created is now added to your VSIX project. In windows explorer open your template zip file (extract it somewhere). open the .vstemplate file. first of all remove <ProjectItem SubType="Code" TargetFileName="$fileinputname$.cs" ReplaceParameters="true">Messages.cs</ProjectItem> because the .cs file is not to be intended to be a part of template and it will be generated. change value of ReplaceParameters for your .tt file to true to enable parameter replacement in this file. now right after </TemplateContent> end element, write this: <WizardExtension>   <Assembly>Framework.Messages.Design</Assembly>   <FullClassName>Framework.Messages.Design.MessageDesigner</FullClassName> </WizardExtension>   one other thing that you should do is to edit your .tt file and remove your .cs file. Lines 8 and 9 of your .tt file should be:     var connectionString = "$connectionString$";     var systemName = "$systemName$"; this parameters will be replaced when the item is added to a project. Save the contents to a zip file with same file name and replace the original file.   now again build your VSIX project, uninstall your extension. close VS. now run .vsix file. open vs, add an item of type messages to your project, bingo, your wizard form will show up. fill the fields and click ok, values are replaced in .tt file added.     that’s it. tried so hard to make this post brief, hope it was not so long…   Cheers Maziar

• Magento, NGINX, PHP-FPM, APC, MEMCACHED, 16gb Ram CentOS, Spiking PHP-FPM to 100% CPU

  - by Terry Dunford

  I have been trying to resolve my issue of spiking cpu caused by php-fpm processes. I've reduced the php-fpm config settings to: pm = ondemand pm.max_children = 12 pm.start_servers = 2 pm.min_spare_servers = 2 pm.max_spare_servers = 10 pm.max_requests = 500 php_admin_value[memory_limit] = 128M Problem still exists. I'm running a Joomla main site (which is having no problems) and a Magento store in a sub-directory. My server is a Linux CentOS, running NGINX, APC, Memcached, Full Page Cache and php-fpm. My server has 8 cores and 16gb dedicated ram. My host has shut down my server several times the past week because my php-fpm processes are consuming the entire network. A lot of the individual php-fpm processes are getting over 50% cpu. I've hired several "professionals" and none of them was able to help me, so now broke and stumped, I'm turning to you guys for help. So any suggestions would be greatly appreciated. I turned on slow php logs and here are some of the latest results: [01-Apr-2012 14:26:12] [pool magento] pid 21537 script_filename = /home/flyfish/www/flyshop/index.php [0x0000000011a394f8]

• Cisco SR520w FE - WAN Port Stops Working

  - by Mike Hanley

  I have setup a Cisco SR520W and everything appears to be working. After about 1-2 days, it looks like the WAN port stops forwarding traffic to the Internet gateway IP of the device. If I unplug and then plug in the network cable connecting the WAN port of the SR520W to my Comcast Cable Modem, traffic startings flowing again. Also, if I restart the SR520W, the traffic will flow again. Any ideas? Here is the running config: Current configuration : 10559 bytes ! version 12.4 no service pad no service timestamps debug uptime service timestamps log datetime msec no service password-encryption ! hostname hostname.mydomain.com !

• Removing the XML Formatter from ASP.NET Web API Applications

  - by Rick Strahl

  ASP.NET Web API's default output format is supposed to be JSON, but when I access my Web APIs using the browser address bar I'm always seeing an XML result instead. When working on AJAX application I like to test many of my AJAX APIs with the browser while working on them. While I can't debug all requests this way, GET requests are easy to test in the browser especially if you have JSON viewing options set up in your various browsers. If I preview a Web API request in most browsers I get an XML response like this: Why is that? Web API checks the HTTP Accept headers of a request to determine what type of output it should return by looking for content typed that it has formatters registered for. This automatic negotiation is one of the great features of Web API because it makes it easy and transparent to request different kinds of output from the server. In the case of browsers it turns out that most send Accept headers that look like this (Chrome in this case): Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Web API inspects the entire list of headers from left to right (plus the quality/priority flag q=) and tries to find a media type that matches its list of supported media types in the list of formatters registered. In this case it matches application/xml to the Xml formatter and so that's what gets returned and displayed. To verify that Web API indeed defaults to JSON output by default you can open the request in Fiddler and pop it into the Request Composer, remove the application/xml header and see that the output returned comes back in JSON instead. An accept header like this: Accept: text/html,application/xhtml+xml,*/*;q=0.9 or leaving the Accept header out altogether should give you a JSON response. Interestingly enough Internet Explorer 9 also displays JSON because it doesn't include an application/xml Accept header: Accept: text/html, application/xhtml+xml, */* which for once actually seems more sensible. Removing the XML Formatter We can't easily change the browser Accept headers (actually you can by delving into the config but it's a bit of a hassle), so can we change the behavior on the server? When working on AJAX applications I tend to not be interested in XML results and I always want to see JSON results at least during development. Web API uses a collection of formatters and you can go through this list and remove the ones you don't want to use - in this case the XmlMediaTypeFormatter. To do this you can work with the HttpConfiguration object and the static GlobalConfiguration object used to configure it: protected void Application_Start(object sender, EventArgs e) { // Action based routing (used for RPC calls) RouteTable.Routes.MapHttpRoute( name: "StockApi", routeTemplate: "stocks/{action}/{symbol}", defaults: new { symbol = RouteParameter.Optional, controller = "StockApi" } ); // WebApi Configuration to hook up formatters and message handlers RegisterApis(GlobalConfiguration.Configuration); } public static void RegisterApis(HttpConfiguration config) { // remove default Xml handler var matches = config.Formatters .Where(f = f.SupportedMediaTypes .Where(m = m.MediaType.ToString() == "application/xml" || m.MediaType.ToString() == "text/xml") .Count() 0) .ToList() ; foreach (var match in matches) config.Formatters.Remove(match); } } That LINQ code is quite a mouthful of nested collections, but it does the trick to remove the formatter based on the content type. You can also look for the specific formatter (XmlMediatTypeFormatter) by its type name which is simpler, but it's better to search for the supported types as this will work even if there are other custom formatters added. Once removed, now the browser request results in a JSON response: It's a simple solution to a small debugging task that's made my life easier.

• Rotate a Video 90 degrees with VLC or Windows Live Movie Maker

  - by DigitalGeekery

  Have you ever captured video with your cell phone or camcorder only to discover when you play it back on your computer that the video is rotated 90 degrees? Or maybe you shot it that way on purpose because you preferred portrait style to a landscape view? Before you go straining your neck or flipping your monitor on it’s side to watch your video, we’ll show you a few easier methods. If you simply want to rotate the video while you watch it, we’ll show you how to accomplish that with VLC Media Player. If you want to convert the video so it is rotated permanently, we’ll show you how to do that with Windows Live Movie Maker and output your video as a WMV file. Rotate and Watch a Video in VLC Download, install, and run VLC Media Player. (See download link below)   Open your video file by going to Media  > Open File… and browsing for your file. Or, by just dragging and dropping your video onto the VLC player.   Choose Tools from the Menu bar and select Effects and Filters. On the Video Effects tab, tick the Transform checkbox and choose your degrees of rotation. The video is rotated counter-clockwise, so to rotate clockwise 90 degrees you’ll want to choose Rotate by 270 degrees.   Now you can enjoy your video the way it was intended to be viewed. Rotate and Convert the Video with Windows Live Movie Maker Starting with Windows 7, Windows Movie Maker no longer comes pre-installed with the OS. It’s now part of the Windows Live suite that is available as a separate, free download for Windows 7 and Vista. (Windows XP is not supported) You can find the link to our detailed instruction on how to install Windows Live at the end of the article. To add your video files to Windows Movie Maker, click on Add videos and photos on the Home tab, or drag and drop the video into the blank area on the right side of the application. Next, you’ll need to rotate the video. Staying on the Home tab, click on the Rotate right 90° or Rotate left 90°.   You’ll see your video is now oriented properly on the left.   To save and convert your video to WMV format, click the Movie Maker tab just to the left of the Home tab. Hover your cursor over Save movie, and then select your output settings. You also have the option to burn directly to DVD. Browse for a location to save it and rename the output file if you’d like. Click Save. You’ll be notified when the file is complete. Now you’ll have your video properly oriented in WMV file format.   These are two rather easy ways to accomplish rotating your video. Unfortunately, Windows Live Movie Maker doesn’t give you a lot of  options for output. If you want to output to a file, your only choice is WMV format or DVD. However, previous versions will also allow you to export to AVI. How-To Geek’s Install Windows Live Essentials In Windows 7 Article.

• Unit Testing Framework for XQuery

  - by Knut Vatsendvik

  This posting provides a unit testing framework for XQuery using Oracle Service Bus. It allows you to write a test case to run your XQuery transformations in an automated fashion. When the test case is run, the framework returns any differences found in the response. The complete code sample with install instructions can be downloaded from here. Writing a Unit Test You start a new Test Case by creating a Proxy Service from Workshop that comes with Oracle Service Bus. In the General Configuration page select Service Type to be Messaging Service           In the Message Type Configuration page link both the Request & Response Message Type to the TestCase element of the UnitTest.xsd schema                 The TestCase element consists of the following child elements The ID and optional Name element is simply used for reference. The Transformation element is the XQuery resource to be executed. The Input elements represents the input to run the XQuery with. The Output element represents the expected output. These XML documents are “also” represented as an XQuery resource where the XQuery function takes no arguments and returns the XML document. Why not pass the test data with the TestCase? Passing an XML structure in another XML structure is not very easy or at least not very human readable. Therefore it was chosen to represent the test data as an loadable resource in the OSB. However you are free to go ahead with another approach on this if wanted. The XMLDiff elements represents any differences found. A sample on input is shown here. Modeling the Message Flow Then the next step is to model the message flow of the Proxy Service. In the Request Pipeline create a stage node that loads the test case input data.      For this, specify a dynamic XQuery expression that evaluates at runtime to the name of a pre-registered XQuery resource. The expression is of course set by the input data from the test case.           Add a Run stage node. Assign the result of the XQuery, that is to be run, to a context variable. Define a mapping for each of the input variables added in previous stage.     Add a Compare stage. Like with the input data, load the expected output data. Do a compare using XMLDiff XQuery provided where the first argument is the loaded output test data, and the second argument the result from the Run stage. Any differences found is replaced back into the test case XMLDiff element. In case of any unexpected failure while processing, add an Error Handler to the Pipeline to capture the fault. To pass back the result add the following Insert action In the Response Pipeline. A sample on output is shown here.

• Integrated webcam in lenovo t410 not working with 12.04

  - by kristianp

  I have a Lenovo T410 with an inbuilt webcam and I haven't been able to get the webcam working. I tried skype, cheese, both just give me a black window. The microphone works fine with skype, by the way. Can anyone provide any clues please? The webcam is enabled in the bios, but there is no light indicating the webcam is on (not sure if there should be, though). I tried this on Kubuntu 11.10 and have upgraded to 12.04 with the same results. The Fn-F6 keyboard combination doens't seem to do anything either. EDIT: I got the webcam replaced, it looks like it was a hardware problem, because it works fine now.

• Convert old AVI files to a modern format

  - by iWerner

  Hi, we have a collection of old home videos that were saved in AVI format a long time ago. I want to convert these files to a more modern format because the Totem Movie Player that comes with Ubuntu 10.4 seems to be the only program capable of playing them. The files seem to be encoded with a MJPEG codec, and playing them in VLC or Windows Media Player plays only the sound but there is no video. Avidemux was able to open the files, but the quality of the video is severely degraded: The video skips frames and is interlaced (it's not interlaced when playing it in Totem). Neither ffmpeg nor mencoder seems to be able to read the video stream. mencoder reports that it is using ffmpeg's codec. Here's a section from its output: ========================================================================== Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family [mjpeg @ 0x92a7260]mjpeg: using external huffman table [mjpeg @ 0x92a7260]mjpeg: error using external huffman table, switching back to internal Unsupported PixelFormat -1 Selected video codec: [ffmjpeg] vfm: ffmpeg (FFmpeg MJPEG) while running ffmpeg produces the following: $ ffmpeg -i input.avi output.avi FFmpeg version SVN-r0.5.1-4:0.5.1-1ubuntu1, Copyright (c) 2000-2009 Fabrice Bellard, et al. configuration: --extra-version=4:0.5.1-1ubuntu1 --prefix=/usr --enable-avfilter --enable-avfilter-lavf --enable-vdpau --enable-bzlib --enable-libgsm --enable-libschroedinger --enable-libspeex --enable-libtheora --enable-libvorbis --enable-pthreads --enable-zlib --disable-stripping --disable-vhook --enable-runtime-cpudetect --enable-gpl --enable-postproc --enable-swscale --enable-x11grab --enable-libdc1394 --enable-shared --disable-static libavutil 49.15. 0 / 49.15. 0 libavcodec 52.20. 1 / 52.20. 1 libavformat 52.31. 0 / 52.31. 0 libavdevice 52. 1. 0 / 52. 1. 0 libavfilter 0. 4. 0 / 0. 4. 0 libswscale 0. 7. 1 / 0. 7. 1 libpostproc 51. 2. 0 / 51. 2. 0 built on Mar 4 2010 12:35:30, gcc: 4.4.3 [avi @ 0x87952c0]non-interleaved AVI Input #0, avi, from 'input.avi': Duration: 00:00:15.24, start: 0.000000, bitrate: 22447 kb/s Stream #0.0: Video: mjpeg, yuvj422p, 720x544, 25 tbr, 25 tbn, 25 tbc Stream #0.1: Audio: pcm_s16le, 44100 Hz, stereo, s16, 1411 kb/s Output #0, avi, to 'output.avi': Stream #0.0: Video: mpeg4, yuv420p, 720x544, q=2-31, 200 kb/s, 90k tbn, 25 tbc Stream #0.1: Audio: mp2, 44100 Hz, stereo, s16, 64 kb/s Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Press [q] to stop encoding frame= 0 fps= 0 q=0.0 Lsize= 143kB time=15.23 bitrate= 76.9kbits/s video:0kB audio:119kB global headers:0kB muxing overhead 20.101777% So the problem is that output does not contain any video, as evidenced by the video:0kB at the end.

• Projective texture and deferred lighting

  - by Vodácek

  In my previous question, I asked whether it is possible to do projective texturing with deferred lighting. Now (more than half a year later) I have a problem with my implementation of the same thing. I am trying to apply this technique in light pass. (my projector doesn't affect albedo). I have this projector View a Projection matrix: Matrix projection = Matrix.CreateOrthographicOffCenter(-halfWidth * Scale, halfWidth * Scale, -halfHeight * Scale, halfHeight * Scale, 1, 100000); Matrix view = Matrix.CreateLookAt(Position, Target, Vector3.Up); Where halfWidth and halfHeight is are half of the texture's width and height, Position is the Projector's position and target is the projector's target. This seems to be ok. I am drawing full screen quad with this shader: float4x4 InvViewProjection; texture2D DepthTexture; texture2D NormalTexture; texture2D ProjectorTexture; float4x4 ProjectorViewProjection; sampler2D depthSampler = sampler_state { texture = <DepthTexture>; minfilter = point; magfilter = point; mipfilter = point; }; sampler2D normalSampler = sampler_state { texture = <NormalTexture>; minfilter = point; magfilter = point; mipfilter = point; }; sampler2D projectorSampler = sampler_state { texture = <ProjectorTexture>; AddressU = Clamp; AddressV = Clamp; }; float viewportWidth; float viewportHeight; // Calculate the 2D screen position of a 3D position float2 postProjToScreen(float4 position) { float2 screenPos = position.xy / position.w; return 0.5f * (float2(screenPos.x, -screenPos.y) + 1); } // Calculate the size of one half of a pixel, to convert // between texels and pixels float2 halfPixel() { return 0.5f / float2(viewportWidth, viewportHeight); } struct VertexShaderInput { float4 Position : POSITION0; }; struct VertexShaderOutput { float4 Position :POSITION0; float4 PositionCopy : TEXCOORD1; }; VertexShaderOutput VertexShaderFunction(VertexShaderInput input) { VertexShaderOutput output; output.Position = input.Position; output.PositionCopy=output.Position; return output; } float4 PixelShaderFunction(VertexShaderOutput input) : COLOR0 { float2 texCoord =postProjToScreen(input.PositionCopy) + halfPixel(); // Extract the depth for this pixel from the depth map float4 depth = tex2D(depthSampler, texCoord); //return float4(depth.r,0,0,1); // Recreate the position with the UV coordinates and depth value float4 position; position.x = texCoord.x * 2 - 1; position.y = (1 - texCoord.y) * 2 - 1; position.z = depth.r; position.w = 1.0f; // Transform position from screen space to world space position = mul(position, InvViewProjection); position.xyz /= position.w; //compute projection float3 projection=tex2D(projectorSampler,postProjToScreen(mul(position,ProjectorViewProjection)) + halfPixel()); return float4(projection,1); } In first part of pixel shader is recovered position from G-buffer (this code I am using in other shaders without any problem) and then is tranformed to projector viewprojection space. Problem is that projection doesn't appear. Here is an image of my situation: The green lines are the rendered projector frustum. Where is my mistake hidden? I am using XNA 4. Thanks for advice and sorry for my English. EDIT: Shader above is working but projection was too small. When I changed the Scale property to a large value (e.g. 100), the projection appears. But when the camera moves toward the projection, the projection expands, as can bee seen on this YouTube video.

  I am using a Dell xps l702x and I am using ubuntu 10.04 because I need to use f77 (don't ask) and I wasn't able to get it working on later versions of ubuntu. I cannot use the wifi at all.

Therefore, I can't be sure whether it still works on that or not. It used to, though.

• Set width of Button in Android

  - by Mohit Deshpande

  How can I set a fixed width for an Android button? Everytime I try to set a fixed width it fills the current parent (the RelativeView). Here is my XML: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout android:id="@+id/relativelayout" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> <EditText android:layout_height="wrap_content" android:editable="false" android:layout_width="fill_parent" android:id="@+id/output"></EditText> <Button android:layout_height="wrap_content" android:id="@+id/Button01" android:layout_below="@id/output" android:text="7" android:layout_width="wrap_content"></Button> <Button android:layout_below="@id/output" android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/Button02" android:layout_toRightOf="@+id/Button01" android:text="8"></Button> <Button android:layout_below="@id/output" android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/Button03" android:layout_toRightOf="@+id/Button02" android:text="9"></Button> </RelativeLayout> How would I give it a FIXED width?

• Issue with Sharepoint 2010 application page

  - by Matt Moriarty

  I am relatively new to Sharepoint and am using version 2010. I am having a problem with the following code in an application page I am trying to build: using System; using Microsoft.SharePoint; using Microsoft.SharePoint.WebControls; using System.Text; using Microsoft.SharePoint.Administration; using Microsoft.Office.Server; using Microsoft.Office.Server.UserProfiles; using Microsoft.SharePoint.Utilities; namespace SharePointProject5.Layouts.SharePointProject5 { public partial class ApplicationPage1 : LayoutsPageBase { protected void Page_Load(object sender, EventArgs e) { SPContext context = SPContext.Current; StringBuilder output = new StringBuilder(); using(SPSite site = context.Site) using (SPWeb web = site.AllWebs["BDC_SQL"]) { UserProfileManager upmanager = new UserProfileManager(ServerContext.GetContext(site)); string ListMgr = ""; string ADMgr = ""; bool allowUpdates = web.AllowUnsafeUpdates; web.AllowUnsafeUpdates = true; web.Update(); SPListCollection listcollection = web.Lists; SPList list = listcollection["BDC_SQL"]; foreach (SPListItem item in list.Items) { output.AppendFormat("<br>From List - Name & manager: {0} , {1}", item["ADName"], item["Manager_ADName"]); UserProfile uProfile = upmanager.GetUserProfile(item["ADName"].ToString()); output.AppendFormat("<br>From Prof - Name & manager: {0} , {1}", uProfile[PropertyConstants.DistinguishedName], uProfile[PropertyConstants.Manager]); ListMgr = item["Manager_ADName"].ToString(); ADMgr = Convert.ToString(uProfile[PropertyConstants.Manager]); if (ListMgr != ADMgr) { output.AppendFormat("<br>This record requires updating from {0} to {1}", uProfile[PropertyConstants.Manager], item["Manager_ADName"]); uProfile[PropertyConstants.Manager].Value = ListMgr; uProfile.Commit(); output.AppendFormat("<br>This record has had its manager updated"); } else { output.AppendFormat("<br>This record does not need to be updated"); } } web.AllowUnsafeUpdates = allowUpdates; web.Update(); } Label1.Text = output.ToString(); } } } Everything worked fine up until I added in the 'uProfile.Commit();' line. Now I am getting the following error message: Microsoft.SharePoint.SPException was unhandled by user code Message=Updates are currently disallowed on GET requests.

• Is there a C pre-processor which eliminates #ifdef blocks based on values defined/undefined?

  - by Jonathan Leffler

  Original Question What I'd like is not a standard C pre-processor, but a variation on it which would accept from somewhere - probably the command line via -DNAME1 and -UNAME2 options - a specification of which macros are defined, and would then eliminate dead code. It may be easier to understand what I'm after with some examples: #ifdef NAME1 #define ALBUQUERQUE "ambidextrous" #else #define PHANTASMAGORIA "ghostly" #endif If the command were run with '-DNAME1', the output would be: #define ALBUQUERQUE "ambidextrous" If the command were run with '-UNAME1', the output would be: #define PHANTASMAGORIA "ghostly" If the command were run with neither option, the output would be the same as the input. This is a simple case - I'd be hoping that the code could handle more complex cases too. To illustrate with a real-world but still simple example: #ifdef USE_VOID #ifdef PLATFORM1 #define VOID void #else #undef VOID typedef void VOID; #endif /* PLATFORM1 */ typedef void * VOIDPTR; #else typedef mint VOID; typedef char * VOIDPTR; #endif /* USE_VOID */ I'd like to run the command with -DUSE_VOID -UPLATFORM1 and get the output: #undef VOID typedef void VOID; typedef void * VOIDPTR; Another example: #ifndef DOUBLEPAD #if (defined NT) || (defined OLDUNIX) #define DOUBLEPAD 8 #else #define DOUBLEPAD 0 #endif /* NT */ #endif /* !DOUBLEPAD */ Ideally, I'd like to run with -UOLDUNIX and get the output: #ifndef DOUBLEPAD #if (defined NT) #define DOUBLEPAD 8 #else #define DOUBLEPAD 0 #endif /* NT */ #endif /* !DOUBLEPAD */ This may be pushing my luck! Motivation: large, ancient code base with lots of conditional code. Many of the conditions no longer apply - the OLDUNIX platform, for example, is no longer made and no longer supported, so there is no need to have references to it in the code. Other conditions are always true. For example, features are added with conditional compilation so that a single version of the code can be used for both older versions of the software where the feature is not available and newer versions where it is available (more or less). Eventually, the old versions without the feature are no longer supported - everything uses the feature - so the condition on whether the feature is present or not should be removed, and the 'when feature is absent' code should be removed too. I'd like to have a tool to do the job automatically because it will be faster and more reliable than doing it manually (which is rather critical when the code base includes 21,500 source files). (A really clever version of the tool might read #include'd files to determine whether the control macros - those specified by -D or -U on the command line - are defined in those files. I'm not sure whether that's truly helpful except as a backup diagnostic. Whatever else it does, though, the pseudo-pre-processor must not expand macros or include files verbatim. The output must be source similar to, but usually simpler than, the input code.) Status Report (one year later) After a year of use, I am very happy with 'sunifdef' recommended by the selected answer. It hasn't made a mistake yet, and I don't expect it to. The only quibble I have with it is stylistic. Given an input such as: #if (defined(A) && defined(B)) || defined(C) || (defined(D) && defined(E)) and run with '-UC' (C is never defined), the output is: #if defined(A) && defined(B) || defined(D) && defined(E) This is technically correct because '&&' binds tighter than '||', but it is an open invitation to confusion. I would much prefer it to include parentheses around the sets of '&&' conditions, as in the original: #if (defined(A) && defined(B)) || (defined(D) && defined(E)) However, given the obscurity of some of the code I have to work with, for that to be the biggest nit-pick is a strong compliment; it is valuable tool to me. The New Kid on the Block Having checked the URL for inclusion in the information above, I see that (as predicted) there is an new program called Coan that is the successor to 'sunifdef'. It is available on SourceForge and has been since January 2010. I'll be checking it out...further reports later this year, or maybe next year, or sometime, or never.

• Issuing Current Time Increments in StreamInsight (A Practical Example)

  The issuing of a Current Time Increment, Cti, in StreamInsight is very definitely one of the most important concepts to learn if you want your Streams to be responsive. A full discussion of how to issue Ctis is beyond the scope of this article but a very good explanation in addition to Books Online can be found in these three articles by a member of the StreamInsight team at Microsoft, Ciprian Gerea. Time in StreamInsight Series http://blogs.msdn.com/b/streaminsight/archive/2010/07/23/time-in-streaminsight-i.aspx http://blogs.msdn.com/b/streaminsight/archive/2010/07/30/time-in-streaminsight-ii.aspx http://blogs.msdn.com/b/streaminsight/archive/2010/08/03/time-in-streaminsight-iii.aspx A lot of the problems I see with unresponsive or stuck streams on the MSDN Forums are to do with how Ctis are enqueued or in a lot of cases not enqueued. If you enqueue events and never enqueue a Cti then StreamInsight will be perfectly happy. You, on the other hand, will never see data on the output as you have not told StreamInsight to flush the stream. This article deals with a specific implementation problem I had recently whilst working on a StreamInsight project. I look at some possible options and discuss why they would not work before showing the way I solved the problem. The stream of data I was dealing with on this project was very bursty that is to say when events were flowing they came through very quickly and in large numbers (1000 events/sec), but when the stream calmed down it could be a few seconds between each event. When enqueuing events into the StreamInsight engne it is best practice to do so with a StartTime that is given to you by the system producing the event . StreamInsight processes events and it doesn't matter whether those events are being pushed into the engine by a source system or the events are being read from something like a flat file in a directory somewhere. You can apply the same logic and temporal algebra to both situations. Reading from a file is an excellent example of where the time of the event on the source itself is very important. We could be reading that file a long time after it was written. Being able to read the StartTime from the events allows us to define windows that will hold the correct sets of events. I was able to do this with my stream but this is where my problems started. Below is a very simple script to create a SQL Server table and populate it with sample data that will show exactly the problem I had. CREATE TABLE [dbo].[t] ( [c1] [int] PRIMARY KEY, [c2] [datetime] NULL ) INSERT t VALUES (1,'20100810'),(2,'20100810'),(3,'20100810') Column c2 defines the StartTime of the event on the source and as you can see the values in all 3 rows of data is the same. If we read Ciprian’s articles we know that we can define how Ctis get injected into the stream in 3 different places The Stream Definition The Input Factory The Input Adapter I personally have always been a fan of enqueing Ctis through the factory. Below is code typical of what I would use to do this On the class itself I do some inheriting public class SimpleInputFactory : ITypedInputAdapterFactory<SimpleInputConfig>, ITypedDeclareAdvanceTimeProperties<SimpleInputConfig> And then I implement the following function public AdapterAdvanceTimeSettings DeclareAdvanceTimeProperties<TPayload>(SimpleInputConfig configInfo, EventShape eventShape) { return new AdapterAdvanceTimeSettings( new AdvanceTimeGenerationSettings(configInfo.CtiFrequency, TimeSpan.FromTicks(-1)), AdvanceTimePolicy.Adjust); } The configInfo .CtiFrequency property is a value I pass through to define after how many events I want a Cti to be injected and this in turn will flush through the stream of data. I usually pass a value of 1 for this setting. The second parameter determines the CTI timestamp in terms of a delay relative to the events. -1 ticks in the past results in 1 tick in the future, i.e., ahead of the event. The problem with this method though is that if consecutive events have the same StartTime then only one of those events will be enqueued. In this example I use the following to define how I assign the StartTime of my events currEvent.StartTime = (DateTimeOffset)dt.c2; If I go ahead and run my StreamInsight process with this configuration i can see on the output adapter that two events have been removed To see this in a little more depth I can use the StreamInsight Debugger and see what happens internally. What is happening here is that the first event arrives and a Cti is injected with a time of 1 tick after the StartTime of that event (Also the EndTime of the event). The second event arrives and it has a StartTime of before the Cti and even though we specified AdvanceTimePolicy.Adjust on the factory we know that a point event can never be adjusted like this and the event is dropped. The same happens for the third event as well (The second and third events get trumped by the Cti). For a more detailed discussion of why this happens look here http://www.sqlis.com/sqlis/post/AdvanceTimePolicy-and-Point-Event-Streams-In-StreamInsight.aspx We end up with a single event being pushed into the output adapter and our result now makes sense. The next way I tried to solve this problem by changing the value of the second parameter to TimeSpan.Zero Here is how my factory code now looks public AdapterAdvanceTimeSettings DeclareAdvanceTimeProperties<TPayload>(SimpleInputConfig configInfo, EventShape eventShape) { return new AdapterAdvanceTimeSettings( new AdvanceTimeGenerationSettings(configInfo.CtiFrequency, TimeSpan.Zero), AdvanceTimePolicy.Adjust); } What I am doing here is declaring a policy that says inject a Cti together with every event and stamp it with a StartTime that is equal to the start time of the event itself (TimeSpan.Zero). This method has plus points as well as a downside. The upside is that no events will be lost by having the same StartTime as previous events. The Downside is that because the Cti is declared with the StartTime of the event itself then it does not actually flush that particular event because in the StreamInsight algebra, a Cti commits only those events that occurred strictly before them. To flush the events we need a Cti to be enqueued with a greater StartTime than the events themselves. Here is what happened when I ran this configuration As you can see all we got through was the Cti and none of the events. The debugger output shows the stamps on the Cti and the events themselves. Because the Cti issued has the same timestamp (StartTime) as the events then none of the events get flushed. I was nearly there but not quite. Because my stream was bursty it was possible that the next event would not come along for a few seconds and this was far too long for an event to be enqueued and not be flushed to the output adapter. I needed another solution. Two possible solutions crossed my mind although only one of them made sense when I explored it some more. Where multiple events have the same StartTime I could add 1 tick to the first event, two to the second, three to third etc thereby giving them unique StartTime values. Add a timer to manually inject Ctis The problem with the first implementation is that I would be giving the events a new StartTime. This would cause me the following problems If I want to define windows over the stream then some events may not be captured in the right windows and therefore any calculations on those windows I did would be wrong What would happen if we had 10,000 events with the same StartTime? I would enqueue them with StartTime + n ticks. Along comes a genuine event with a StartTime of the very first event + 1 tick. It is now too far in the past as far as my stream is concerned and it would be dropped. Not what I would want to do at all. I decided then to look at the Timer based solution I created a timer on my input adapter that elapsed every 200ms. private Timer tmr; public SimpleInputAdapter(SimpleInputConfig configInfo) { ctx = new SimpleTimeExtractDataContext(configInfo.ConnectionString); this.configInfo = configInfo; tmr = new Timer(200); tmr.Elapsed += new ElapsedEventHandler(t_Elapsed); tmr.Enabled = true; } void t_Elapsed(object sender, ElapsedEventArgs e) { ts = DateTime.Now - dtCtiIssued; if (ts.TotalMilliseconds >= 200 && TimerIssuedCti == false) { EnqueueCtiEvent(System.DateTime.Now.AddTicks(-100)); TimerIssuedCti = true; } }   In the t_Elapsed event handler I find out the difference in time between now and when the last event was processed (dtCtiIssued). I then check to see if that is greater than or equal to 200ms and if the last issuing of a Cti was done by the timer or by a genuine event (TimerIssuedCti). If I didn’t do this check then I would enqueue a Cti every time the timer elapsed which is not something I wanted. If the difference between the two times is greater than or equal to 500ms and the last event enqueued was by a real event then I issue a Cti through the timer to flush the event Queue, otherwise I do nothing. When I enqueue the Ctis into my stream in my ProduceEvents method I also set the values of dtCtiIssued and TimerIssuedCti   currEvent = CreateInsertEvent(); currEvent.StartTime = (DateTimeOffset)dt.c2; TimerIssuedCti = false; dtCtiIssued = currEvent.StartTime; If I go ahead and run this configuration I see the following in my output. As we can see the first Cti gets enqueued as before but then another is enqueued by the timer and because this has a later timestamp it flushes the enqueued events through the engine. Conclusion Hopefully this has shown how the enqueuing of Ctis can have a dramatic effect on the responsiveness of your output in StreamInsight. Understanding the temporal nature of the product is for me one of the most important things you can learn. I have attached my solution for the demos. It is all in one project and testing each variation is a simple matter of commenting and un-commenting the parts in the code we have been dealing with here.

• installed openstack using devstack install shell script but getting 500 error when i try opening dashboard

  - by Arvind

  I followed the instructions at http://devstack.org/guides/single-machine.html to install OpenStack. I first installed Ubuntu on my Windows 7 PC using the officially supported Windows installer for Ubuntu 12.04 LTS. And after that I followed the instructions at above page to install OpenStack. As per instructions, I should be able to access the dashboard aka Horizon, at http://192.168.1.4/ (thats the IP of the PC on which I installed Ubuntu-OpenStack). However I am getting a 500 error web page when I open that. How do I resolve this error? I want to set up a dev environment for OpenStack.

• Does writing data to server using Java URL class require response from server?

  - by gigadot

  I am trying to upload files using Java URL class and I have found a previous question on stack-overflow which explains very well about the details, so I try to follow it. And below is my code adopted from the sniplet given in the answer. My problem is that if I don't make a call to one of connection.getResponseCode() or connection.getInputStream() or connection.getResponseMessage() or anything which is related to reponse from the server, the request will never be sent to server. Why do I need to do this? Or is there any way to write the data without getting the response? P.S. I have developed a server-side uploading servlet which accepts multipart/form-data and save it to files using FileUpload. It is stable and definitely working without any problem so this is not where my problem is generated. import java.io.Closeable; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.OutputStream; import java.io.PrintWriter; import java.net.HttpURLConnection; import java.net.URL; import org.apache.commons.io.IOUtils; public class URLUploader { public static void closeQuietly(Closeable... objs) { for (Closeable closeable : objs) { IOUtils.closeQuietly(closeable); } } public static void main(String[] args) throws IOException { File textFile = new File("D:\\file.zip"); String boundary = Long.toHexString(System.currentTimeMillis()); // Just generate some unique random value. HttpURLConnection connection = (HttpURLConnection) new URL("http://localhost:8080/upslet/upload").openConnection(); connection.setDoOutput(true); connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary); OutputStream output = output = connection.getOutputStream(); PrintWriter writer = writer = new PrintWriter(output, true); // Send text file. writer.println("--" + boundary); writer.println("Content-Disposition: form-data; name=\"file1\"; filename=\"" + textFile.getName() + "\""); writer.println("Content-Type: application/octet-stream"); FileInputStream fin = new FileInputStream(textFile); writer.println(); IOUtils.copy(fin, output); writer.println(); // End of multipart/form-data. writer.println("--" + boundary + "--"); output.flush(); closeQuietly(fin, writer, output); // Above request will never be sent if .getInputStream() or .getResponseCode() or .getResponseMessage() does not get called. connection.getResponseCode(); } }

• The fastest way to resize images from ASP.NET. And it’s (more) supported-ish.

  - by Bertrand Le Roy

  I’ve shown before how to resize images using GDI, which is fairly common but is explicitly unsupported because we know of very real problems that this can cause. Still, many sites still use that method because those problems are fairly rare, and because most people assume it’s the only way to get the job done. Plus, it works in medium trust. More recently, I’ve shown how you can use WPF APIs to do the same thing and get JPEG thumbnails, only 2.5 times faster than GDI (even now that GDI really ultimately uses WIC to read and write images). The boost in performance is great, but it comes at a cost, that you may or may not care about: it won’t work in medium trust. It’s also just as unsupported as the GDI option. What I want to show today is how to use the Windows Imaging Components from ASP.NET APIs directly, without going through WPF. The approach has the great advantage that it’s been tested and proven to scale very well. The WIC team tells me you should be able to call support and get answers if you hit problems. Caveats exist though. First, this is using interop, so until a signed wrapper sits in the GAC, it will require full trust. Second, the APIs have a very strong smell of native code and are definitely not .NET-friendly. And finally, the most serious problem is that older versions of Windows don’t offer MTA support for image decoding. MTA support is only available on Windows 7, Vista and Windows Server 2008. But on 2003 and XP, you’ll only get STA support. that means that the thread safety that we so badly need for server applications is not guaranteed on those operating systems. To make it work, you’d have to spin specialized threads yourself and manage the lifetime of your objects, which is outside the scope of this article. We’ll assume that we’re fine with al this and that we’re running on 7 or 2008 under full trust. Be warned that the code that follows is not simple or very readable. This is definitely not the easiest way to resize an image in .NET. Wrapping native APIs such as WIC in a managed wrapper is never easy, but fortunately we won’t have to: the WIC team already did it for us and released the results under MS-PL. The InteropServices folder, which contains the wrappers we need, is in the WicCop project but I’ve also included it in the sample that you can download from the link at the end of the article. In order to produce a thumbnail, we first have to obtain a decoding frame object that WIC can use. Like with WPF, that object will contain the command to decode a frame from the source image but won’t do the actual decoding until necessary. Getting the frame is done by reading the image bytes through a special WIC stream that you can obtain from a factory object that we’re going to reuse for lots of other tasks: var photo = File.ReadAllBytes(photoPath); var factory = (IWICComponentFactory)new WICImagingFactory(); var inputStream = factory.CreateStream(); inputStream.InitializeFromMemory(photo, (uint)photo.Length); var decoder = factory.CreateDecoderFromStream( inputStream, null, WICDecodeOptions.WICDecodeMetadataCacheOnLoad); var frame = decoder.GetFrame(0); We can read the dimensions of the frame using the following (somewhat ugly) code: uint width, height; frame.GetSize(out width, out height); This enables us to compute the dimensions of the thumbnail, as I’ve shown in previous articles. We now need to prepare the output stream for the thumbnail. WIC requires a special kind of stream, IStream (not implemented by System.IO.Stream) and doesn’t directlyunderstand .NET streams. It does provide a number of implementations but not exactly what we need here. We need to output to memory because we’ll want to persist the same bytes to the response stream and to a local file for caching. The memory-bound version of IStream requires a fixed-length buffer but we won’t know the length of the buffer before we resize. To solve that problem, I’ve built a derived class from MemoryStream that also implements IStream. The implementation is not very complicated, it just delegates the IStream methods to the base class, but it involves some native pointer manipulation. Once we have a stream, we need to build the encoder for the output format, which could be anything that WIC supports. For web thumbnails, our only reasonable options are PNG and JPEG. I explored PNG because it’s a lossless format, and because WIC does support PNG compression. That compression is not very efficient though and JPEG offers good quality with much smaller file sizes. On the web, it matters. I found the best PNG compression option (adaptive) to give files that are about twice as big as 100%-quality JPEG (an absurd setting), 4.5 times bigger than 95%-quality JPEG and 7 times larger than 85%-quality JPEG, which is more than acceptable quality. As a consequence, we’ll use JPEG. The JPEG encoder can be prepared as follows: var encoder = factory.CreateEncoder( Consts.GUID_ContainerFormatJpeg, null); encoder.Initialize(outputStream, WICBitmapEncoderCacheOption.WICBitmapEncoderNoCache); The next operation is to create the output frame: IWICBitmapFrameEncode outputFrame; var arg = new IPropertyBag2[1]; encoder.CreateNewFrame(out outputFrame, arg); Notice that we are passing in a property bag. This is where we’re going to specify our only parameter for encoding, the JPEG quality setting: var propBag = arg[0]; var propertyBagOption = new PROPBAG2[1]; propertyBagOption[0].pstrName = "ImageQuality"; propBag.Write(1, propertyBagOption, new object[] { 0.85F }); outputFrame.Initialize(propBag); We can then set the resolution for the thumbnail to be 96, something we weren’t able to do with WPF and had to hack around: outputFrame.SetResolution(96, 96); Next, we set the size of the output frame and create a scaler from the input frame and the computed dimensions of the target thumbnail: outputFrame.SetSize(thumbWidth, thumbHeight); var scaler = factory.CreateBitmapScaler(); scaler.Initialize(frame, thumbWidth, thumbHeight, WICBitmapInterpolationMode.WICBitmapInterpolationModeFant); The scaler is using the Fant method, which I think is the best looking one even if it seems a little softer than cubic (zoomed here to better show the defects): Cubic Fant Linear Nearest neighbor We can write the source image to the output frame through the scaler: outputFrame.WriteSource(scaler, new WICRect { X = 0, Y = 0, Width = (int)thumbWidth, Height = (int)thumbHeight }); And finally we commit the pipeline that we built and get the byte array for the thumbnail out of our memory stream: outputFrame.Commit(); encoder.Commit(); var outputArray = outputStream.ToArray(); outputStream.Close(); That byte array can then be sent to the output stream and to the cache file. Once we’ve gone through this exercise, it’s only natural to wonder whether it was worth the trouble. I ran this method, as well as GDI and WPF resizing over thirty twelve megapixel images for JPEG qualities between 70% and 100% and measured the file size and time to resize. Here are the results: Size of resized images   Time to resize thirty 12 megapixel images Not much to see on the size graph: sizes from WPF and WIC are equivalent, which is hardly surprising as WPF calls into WIC. There is just an anomaly for 75% for WPF that I noted in my previous article and that disappears when using WIC directly. But overall, using WPF or WIC over GDI represents a slight win in file size. The time to resize is more interesting. WPF and WIC get similar times although WIC seems to always be a little faster. Not surprising considering WPF is using WIC. The margin of error on this results is probably fairly close to the time difference. As we already knew, the time to resize does not depend on the quality level, only the size does. This means that the only decision you have to make here is size versus visual quality. This third approach to server-side image resizing on ASP.NET seems to converge on the fastest possible one. We have marginally better performance than WPF, but with some additional peace of mind that this approach is sanctioned for server-side usage by the Windows Imaging team. It still doesn’t work in medium trust. That is a problem and shows the way for future server-friendly managed wrappers around WIC. The sample code for this article can be downloaded from: http://weblogs.asp.net/blogs/bleroy/Samples/WicResize.zip The benchmark code can be found here (you’ll need to add your own images to the Images directory and then add those to the project, with content and copy if newer in the properties of the files in the solution explorer): http://weblogs.asp.net/blogs/bleroy/Samples/WicWpfGdiImageResizeBenchmark.zip WIC tools can be downloaded from: http://code.msdn.microsoft.com/wictools To conclude, here are some of the resized thumbnails at 85% fant:

• Detect a white square in a black and white image

  - by gcc

  I saw that question i one web site (cite name like that programm.) then i tried to solve but icannot (not my and myfriend homework ) how can i approach to that one (in program.net no solution there is ) Read black & white image data from standard input, and detect a white square in the image. Output the coordinates of the upper left corner of the square, and the width of the square. In the preliminary work, you can print the output and terminate your program after you detect your first square. If you can't find any square on the image, you will print the string: "NO DETECTION". Input (which represents a 2 by 2 square in the center of a 5 by 4 image): 2 2 5 4 0 0 0 0 0 0 0 255 255 0 0 0 255 255 0 0 0 0 0 0 Output: 3 2 2 Input (more comprehensible format of the image, with the same output): 2 6 4 000 000 000 000 000 000 000 000 255 255 255 000 000 000 000 255 255 000 000 000 000 000 000 000 Output: no detection Input can be: 000 255 255 000 000 000 000 255 255 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 000 255 255 255 000 000 000 255 255 255 000 000 000 255 255 255 000 000 000 000 000 000 000 If there are two squares detected, we should use the biggest one

• Filter rows on the basis of "First Name" + "Last Name" in SQL

  - by Raghav Khunger

  Hi, I have a user table in my database which contains two columns FirstName and LastName. Now in my front end there is a textbox to filter out the users from this table. Let's suppose I am taking that input from the front end in the form of a input parameter "@SEARCHKEYWORD". I have created a sample below: DECLARE @Test TABLE ([ID] INT IDENTITY, [FNAME] NVARCHAR(100), [LNAME] NVARCHAR(100) ) INSERT INTO @Test( FNAME, LNAME ) SELECT 'John','Resig' UNION ALL SELECT 'Dave','Ward' UNION ALL SELECT 'Peter','Smith' UNION ALL SELECT 'Dave','Smith' UNION ALL SELECT 'Girija','Acharya' UNION ALL SELECT 'Devendra', 'Gujel' UNION ALL SELECT 'Arjit', 'Gupta' DECLARE @SEARCHKEYWORD NVARCHAR(100) SELECT * FROM @Test WHERE FNAME +' '+ LNAME LIKE @SEARCHKEYWORD i.e. so far I have thought of this query to filter out the rows but it is not giving the desired results: SELECT * FROM @Test WHERE FNAME +' '+ LNAME LIKE @SEARCHKEYWORD Here are the desired outputs which I needed for the inputs mentioned below: --WHEN @SEARCHKEYWORD='John Resig' --Desired OUTPUT: the row which contains 'John','Resig' --WHEN @SEARCHKEYWORD='Ac' --Desired OUTPUT: the row which contains 'Girija','Acharya' --WHEN @SEARCHKEYWORD='Smith' --Desired OUTPUT: the row which contains 'Peter','Smith' and 'Dave','Smith' --WHEN @SEARCHKEYWORD='g' --Desired OUTPUT: the row which contains 'Devendra', 'Gujel' and 'Arjit', 'Gupta' --WHEN @SEARCHKEYWORD='Smith' --Desired OUTPUT: the row which contains 'Peter','Smith' and 'Dave','Smith'
