  • Linq to SQL Where clause based on field selected at runtime

    - by robasaurus
    I'm trying to create a simple reusable search using LINQ to SQL. I pass in a list of words entered in a search box. The results are then filtered based on this criteria. private IQueryable<User> BasicNameSearch(IQueryable<User> usersToSearch, ICollection<string> individualWordsFromSearch) { return usersToSearch .Where(user => individualWordsFromSearch.Contains(user.Forename.ToLower()) || individualWordsFromSearch.Contains(user.Surname.ToLower())); } Now I want this same search functionality on a different datasource and want to dynamically select the fields to apply the search to. For instance instead of IQueryable of Users I may have an IQueryable of Cars and instead of firstname and surname the search goes off Make and Model. Basically the goal is to reuse the search logic by dynamically selecting what to search on at runtime.

  • Java text classification problem

    - by yox
    Hello, I have a set of Books objects, classs Book is defined as following : Class Book{ String title; ArrayList<tags> taglist; } Where title is the title of the book, example : Javascript for dummies. and taglist is a list of tags for our example : Javascript, jquery, "web dev", .. As I said a have a set of books talking about different things : IT, BIOLOGY, HISTORY, ... Each book has a title and a set of tags describing it.. I have to classify automaticaly those books into separated sets by topic, example : IT BOOKS : Java for dummies Javascript for dummies Learn flash in 30 days C++ programming HISTORY BOOKS : World wars America in 1960 Martin luther king's life BIOLOGY BOOKS : .... Do you guys know a classification algorithm/method to apply for that kind of problems ? A solution is to use an external API to define the category of the text, but the problem here is that books are in different languages : french, spanish, english ..

  • Ramifications of CheckForIllegalCrossThreadCalls=false

    - by Ron Skufca
    I recently updated an application from VS2003 to VS2008 and I knew I would be dealing with a host of "Cross-thread operation not valid: Control 'myControl' accessed from a thread other than the thread it was created on" I am handling this in what I beleive is the correct way (see code sample below). I am running into numerous controls that are going to need a similar fix. Not wanting to have similar code for every label, textbox etc.. that are being accessed by a non UI thread. What are the ramifications of just setting the CheckForIllegalCrossThreadCalls = false for the entire app? I found a CodeProject article with various workarounds and a warning at the bottom to NOT set the property. I am looking for other opinions/experiences on this issue. private void ShowStatus(string szStatus) { try { if (this.statusBar1.InvokeRequired) { BeginInvoke(new MethodInvoker(delegate() { ShowStatus(szStatus); })); } else { statusBar1.Panels[0].Text = szStatus; } } catch (Exception ex) { LogStatus.WriteErrorLog(ex, "Error", "frmMNI.ShowStatus()"); } }

  • How can I get a writable path on the iPhone?

    - by Kendall Helmstetter Gelner
    I am posting this question because I had a complete answer for this written out for another post, when I found it did not apply to the original but I thought was too useful to waste. Thus I have also made this a community wiki, so that others may flesh out question and answer(s). If you find the answer useful, please vote up the question - being a community wiki I should not get points for this voting but it will help others find it How can I get a path into which file writes are allowed on the iPhone? You can (misleadingly) write anywhere you like on the Simulator, but on the iPhone you are only allowed to write into specific locations.

  • Searching for patterns to create a TCP Connection Pool for high performance messaging

    - by JoeGeeky
    I'm creating a new Client / Server application in C# and expect to have a fairly high rate of connections. That made me think of database connection pools which help mitigate the expense of creating and disposing connections between the client and database. I would like to create a similar capability for my application and haven't been able to find any good examples of how to apply this pattern. Do I really need to spin up an instance of a TcpClient every time I want to send a message to the server and receive a receipt message? Each connection is expected to transport between 1-5KB with each receiving a 1KB response message. I realize this question is somewhat vague, but I am starting from scratch so I am open to suggestions. Even if that means my suppositions are all wrong.

  • Jquery and Ajax to Dynamically load IFrame

    - by JCHASE11
    I have a script that dynamically loads iframes inside a webpage. You can see the demo here: DEMO I want to use jquery to achieve the same rseult, but with a nice sliding effect. Basically, I have 10 links on a page. When the link is clicked, I want the iframe window to load in the new content and apply an effect to the transition. Does anyone know of any plugins that exist for this. I am not experienced enough to write a script from scratch, so any help would be much appreciated!

I want check if a fileis copied right in shared folder Andre Krijen says me the best way is to create a MD5Hash of original file. When the file is copied, verify the MD5Hash file of the copied one with the original one. I have big pdf files. apply md5 hash about big file, any performance problem ?? If I only check (without generate md5 hash) Length of files (original and copied) ?? Thanks in advanced.

  • Sum an Array - Objective-C

    - by Graham
    Hi Guys, I'm just starting out and I'm looking for an easy way to sum a simple array. I've read into apple developer site on key value coding and I don't understand how to apply that to my array or if that's the appropriate way to sum this. My stumbling block with the key value coding is the .keypathToProperty - I can sort of understand that you need a further reference in a 2D array but they don't show the array code, only the keypath to the title of the row so I can't figure it out yet. NSMutableArray *numArray = [NSMutableArray arrayWithCapacity:4]; [numArray addObject:num1]; [numArray addObject:num2]; [numArray addObject:num3]; [numArray addObject:num4]; I appreciate the replies! Thanks Graham

  • Switching/Linking to another external stylesheet in a .js file using Ruby on Rails

    - by Jake
    Im learning JQuery from a Sitepoint Book but Im trying to apply all the lessons to a Rails App. In one lesson, we are taught how to switch to a different stylesheet if the browser window is resized beyond a certain point. Here's the javascript code: if ($('body').width() > 900) { $('<link rel="stylesheet" href="wide.css" type="text/css" />') .appendTo('head'); } else { $('link[href=wide.css]').remove(); } Rails doesn't seem to want to link to the new stylesheet using 'link rel'. I've tried using the Rails helper: <%= stylesheet_link_tag 'base', :media => 'screen' %> but that doesn't work in a .js file. How do I link to an external stylesheet in a .js file using Ruby? Can I use Ruby on Rails code in a .js file? Thanks.

  • Learning JavaScript... Should I skip straight to the good stuff (the frameworks)?

    - by Grogs
    I learnt HTML/CSS a good few years back, then PHP a little later. I've recently become interesting in web development again, just started playing with frameworks like Django and RoR. I'm curious as to how much time/effort I should spend learning straight JS before looking at frameworks. I've been reading through a let of articles called Mastering AJAX by Brett McLaughlin which seems quite good, but I'm seeing a lot of stuff (such as cross browser compatibility - even for things like XMLHttpRequest) coming up which look like they would be non-issues if using a framework. So, should I keep reading through these articles and try to build stuff using basic JS, or should I just start looking into jQuery and the like? Also, I've been watching a few videos regarding GWT from Google I/O. I've been learning Java over the last year, built a few medium sized apps in it. I'm wondering if GWT is something that's worth going straight to, along with gQuery?

  • Any really modern, good-looking desktop apps that are developed with PyQt/PySide?

    - by Edwin
    Hi, I have started using Python for web development recently, it's kinda cool; I have seen programs that are developed in QT/C++, which is good enough in terms of esthetics; I have just noticed the new PySide project (which brings LGPL Qt license to Python and it doesn't support Windows yet). In view of the above, I see the possibility of using Python + PyQt/PySide to develop cross platform apps in the future :) but I have several doubts right now: Can PyQty/PySide be used to develop really complex/modern UI? Can somebody give me some points to have a look at some nice-looking screenshots of apps that are developed in Python+QT? What about the performance? Thanks in advance!

  • Function Object in Java .

    - by Tony
    I wanna implement a javascript like method in java , is this possible ? Say , I have a Person class : public class Person { private String name ; private int age ; // constructor ,accessors are omitted } And a list with Person objects: Person p1 = new Person("Jenny",20); Person p2 = new Person("Kate",22); List<Person> pList = Arrays.asList(new Person[] {p1,p2}); I wanna implement a method like this: modList(pList,new Operation (Person p) { incrementAge(Person p) { p.setAge(p.getAge() + 1)}; }); modList receives two params , one is a list , the other is the "Function object", it loops the list ,and apply this function to every element in the list. In functional programming language,this is easy , I don't know how java do this? Maybe could be done through dynamic proxy, does that have a performance trade off?

  • R: Using sapply on vector of POSIXct

    - by Chris
    I have what may be a very simple question. I want to process a column of POSIXct objects from a dataframe and generate a vector of datetime strings. I tried to use the following sapply call dt <- sapply(df$datetime, function(x) format(x,"%Y-%m-%dT%H:%M:%S")) but to no avail. I keep getting the following error Error in prettyNum(.Internal(format(x, trim, digits, nsmall, width, 3L, : invalid 'trim' argument When I apply this function to a single POSIXct object from the column, I have no problem. So I'm stumped at the moment about what the problem is. Do I need to do something special with POSIXct objects?

  • How can one make a web-site accessible only when someone has a dongle?

    - by Brian M. Hunt
    Suppose you want to add an extra layer of credentials on top of a SSL-encrypted login/password, but you don't want to increase complexity to the user. Is there a way to add the requirement of the possession of a dongle to web-server authentication schemes with existing cross-platform browser capabilities? In other words, to get access to the web-site, you would need a username, password, and a USB dongle that has been plugged into the client computer. The dongle would presumably do some sort of challenge/response. It'd be ideal if this dongle solution worked with Firefox automatically or with the simple addition of a plugin. Thoughts and suggestions are appreciated.

  • Format number as I type Expand this post

    - by conorhiggins
    Hi I am working on an app at the moment that requires number input to be formatted as the textfield changes as well as perform a calculation. I have the text fields set up so that as the user types notifications are passed out and a calculation is performed. However what I need to do now is format the text to be in this style: €1,000,000 rather than 1000000. I have this working for the output of the calculation already but everytime I try to apply it to the input text the simulator seems to crash or at least freezes for a while. I'd imagine its a simple enough fix.

  • "Access is denied" error on accessing iframe document object

    - by Ovesh
    For posting AJAX forms in a form with many parameters, I am using a solution of creating an iframe, posting the form to it by POST, and then accessing the iframe's content. specifically, I am accessing the content like this: $("some_iframe_id").get(0).contentWindow.document I tested it and it worked. On some of the pages, I started getting an "Access is denied" error. As far as I know, this shouldn't happen if the iframe is served from the same domain. I'm pretty sure it was working before. Anybody have a clue? If I'm not being clear enough: I'm posting to the same domain. So this is not a cross-domain request. I am testing on IE only. P.S. I can't use simple ajax POST queries (don't ask...)

  • When/Why ( if ever ) should i think about doing Generic Programming/Meta Programming

    - by hotadvice
    Hi there IMHO to me OOPS, design patterns make sense and i have been able to apply them practically. But when it comes to "generic programming /meta programming" of the Modern C++ kind, i am left confused. -- Is it a new programming/design paradigm ? -- Is it just limited to "library development"? If not, What design/coding situations call for using meta programming/generic programming. -- Does using templates mean i am doing generic programming? I have googled a lot on this topic but do not grasp the BIG PICTURE fully. Also see this post. After reading dicussions here under, up till now, I am sure ( might still not be correct): a) Generic programming and meta programming are two different concepts.

  • Double.Parse - Internationalization problem

    - by oz
    This is driving me crazy. I have the following string in a ASP.NET 2.0 WebForm Page string s = "0.009"; Simple enough. Now, if my culture is Spanish - which is "es-ES" - and I try to convert the string to Double, I do the following: double d = Double.Parse(s, new CultureInfo("es-ES")); what I'd expect is 0,009. Instead, I get 9. I understand that .NET thinks it is a thousand separator, which in en-US is a comma, but shouldn't it take the culture info I'm passing to the parse method and apply the correct format to the conversion? If I do double d = 0.009D; string formatted = d.ToString(new CultureInfo("es-ES")); formatted is now 0,009. Anybody?

  • OpenGL textures trigger error 1281 and strange background behavior

    - by user3714670
    I am using SOIL to apply textures to VBOs, without textures i could change the background and display black (default color) vbos easily, but now with textures, openGL is giving an error 1281, the background is black and some textures are not applied. There must be something i didn't understand about applying/loading the textures. BUt the texture IS applied (nothing else is working though), the error is applied when i try to use the shader program however i checked the compilation of these and no problems were written. Here is the code i use to load textures, once loaded it is kept in memory, it mostly comes from the example of SOIL : texture = SOIL_load_OGL_single_cubemap( filename, SOIL_DDS_CUBEMAP_FACE_ORDER, SOIL_LOAD_AUTO, SOIL_CREATE_NEW_ID, SOIL_FLAG_POWER_OF_TWO | SOIL_FLAG_MIPMAPS | SOIL_FLAG_DDS_LOAD_DIRECT ); if( texture > 0 ) { glEnable( GL_TEXTURE_CUBE_MAP ); glEnable( GL_TEXTURE_GEN_S ); glEnable( GL_TEXTURE_GEN_T ); glEnable( GL_TEXTURE_GEN_R ); glTexGeni( GL_S, GL_TEXTURE_GEN_MODE, GL_REFLECTION_MAP ); glTexGeni( GL_T, GL_TEXTURE_GEN_MODE, GL_REFLECTION_MAP ); glTexGeni( GL_R, GL_TEXTURE_GEN_MODE, GL_REFLECTION_MAP ); glBindTexture( GL_TEXTURE_CUBE_MAP, texture ); std::cout << "the loaded single cube map ID was " << texture << std::endl; } else { std::cout << "Attempting to load as a HDR texture" << std::endl; texture = SOIL_load_OGL_HDR_texture( filename, SOIL_HDR_RGBdivA2, 0, SOIL_CREATE_NEW_ID, SOIL_FLAG_POWER_OF_TWO | SOIL_FLAG_MIPMAPS ); if( texture < 1 ) { std::cout << "Attempting to load as a simple 2D texture" << std::endl; texture = SOIL_load_OGL_texture( filename, SOIL_LOAD_AUTO, SOIL_CREATE_NEW_ID, SOIL_FLAG_POWER_OF_TWO | SOIL_FLAG_MIPMAPS | SOIL_FLAG_DDS_LOAD_DIRECT ); } if( texture > 0 ) { // enable texturing glEnable( GL_TEXTURE_2D ); // bind an OpenGL texture ID glBindTexture( GL_TEXTURE_2D, texture ); std::cout << "the loaded texture ID was " << texture << std::endl; } else { glDisable( GL_TEXTURE_2D ); std::cout << "Texture loading failed: '" << SOIL_last_result() << "'" << std::endl; } } and how i apply it when drawing : GLuint TextureID = glGetUniformLocation(shaderProgram, "myTextureSampler"); if(!TextureID) cout << "TextureID not found ..." << endl; // glEnableVertexAttribArray(TextureID); glActiveTexture(GL_TEXTURE0); if(SFML) sf::Texture::bind(sfml_texture); else { glBindTexture (GL_TEXTURE_2D, texture); // glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, 1024, 768, 0, GL_RGB, GL_UNSIGNED_BYTE, &texture); } glUniform1i(TextureID, 0); I am not sure that SOIL is adapted to my program as i want something as simple as possible (i used sfml's texture object which was the best but i can't anymore), but if i can get it to work it would be great. EDIT : After narrowing the code implied by the error, here is the code that provokes it, it is called between texture loading and bos drawing : glEnableClientState(GL_VERTEX_ARRAY); //this gives the error : glUseProgram(this->shaderProgram); if (!shaderLoaded) { std::cout << "Loading default shaders" << std::endl; if(textured) loadShaderProgramm(texture_vertexSource, texture_fragmentSource); else loadShaderProgramm(default_vertexSource,default_fragmentSource); } glm::mat4 Projection = camera->getPerspective(); glm::mat4 View = camera->getView(); glm::mat4 Model = glm::mat4(1.0f); Model[0][0] *= scale_x; Model[1][1] *= scale_y; Model[2][2] *= scale_z; glm::vec3 translate_vec(this->x,this->y,this->z); glm::mat4 object_transform = glm::translate(glm::mat4(1.0f),translate_vec); glm::quat rotation = QAccumulative.getQuat(); glm::mat4 matrix_rotation = glm::mat4_cast(rotation); object_transform *= matrix_rotation; Model *= object_transform; glm::mat4 MVP = Projection * View * Model; GLuint ModelID = glGetUniformLocation(this->shaderProgram, "M"); if(ModelID ==-1) cout << "ModelID not found ..." << endl; GLuint MatrixID = glGetUniformLocation(this->shaderProgram, "MVP"); if(MatrixID ==-1) cout << "MatrixID not found ..." << endl; GLuint ViewID = glGetUniformLocation(this->shaderProgram, "V"); if(ViewID ==-1) cout << "ViewID not found ..." << endl; glUniformMatrix4fv(MatrixID, 1, GL_FALSE, &MVP[0][0]); glUniformMatrix4fv(ModelID, 1, GL_FALSE, &Model[0][0]); glUniformMatrix4fv(ViewID, 1, GL_FALSE, &View[0][0]); drawObject();

  • Google Datastore low-level api query by key property

    - by Keyur
    I'm using the low-level google datastore api and I want to query by the key property and another property (let's call it category). I need to query based on a list of keys for which I'll use the IN operator. I know that the max. number of values you can provide for the IN clause is 30. I have 2 questions: Does the limit of 30 IN values apply to the key property as well? Do I need to create a composite index on {_key_ + category} or just on {category} for this query? Thanks, Keyur

  • How to leverage Spring Integration in a real-world JMS distributed architecture?

    - by ngeek
    For the following scenario I am looking for your advices and tips on best practices: In a distributed (mainly Java-based) system with: many (different) client applications (web-app, command-line tools, REST API) a central JMS message broker (currently in favor of using ActiveMQ) multiple stand-alone processing nodes (running on multiple remote machines, computing expensive operations of different types as specified by the JMS message payload) How would one best apply the JMS support provided by the Spring Integration framework to decouple the clients from the worker nodes? When reading through the reference documentation and some very first experiments it looks like the configuration of an JMS inbound adapter inherently require to use a subscriber, which in a decoupled scenario does not exist. Small side note: communication should happen via JMS text messages (using a JSON data structure for future extensibility).

  • How to call PHP proxy script from JQuery

    - by recipriversexclusion
    I'm trying to get cross-domain Ajax to work. I downloaded a PHP proxy script from the Yahoo Developer site, ran it from command line and verified that it receives the XML from the server with a GET request. Now, I'm trying to connect to the PHP script within JS with no results. I have the following: <script type="text/javascript" src="jquery-1.4.2.js"></script> <script type="text/javascript"> $.ajax({ type:"GET", url:"proxy.php", dataType:"html", success:function(msg){ alert(msg); } }); </script> What this does, though, is to output the source of the PHP script in the alert box, not the XML! Where am I going wrong?
