  • Recent resources on Entity Framework 4

    - by Eric Nelson
    I just posted on the bits you need to install to explore all the features of Entity Framework 4 with the Visual Studio 2010 RC. I’ve also had a quick look (March 12th 2010) to see what new resources are out there on EF4. They appear a little thin on the ground – but there are some gems. The following all caught my attention: Julie Lerman has published 2 How-to-videos on EF4 on pluralsight.com. You need to create a free guest pass to watch them. Getting Started with Entity Framework 4.0 – Session given at Cairo CodeCamp 2010 . This includes ppt and demos. Entity Framework 4 providers – read through the comments What’s new with Entity Framework in Visual Studio 2010 RC Extending the design surface of EF4 using the Extension Starter Kit Persistence Ignorance and EF4 on geekSpeak on channel 9 (poor audio IMHO – I gave up) First of a series of posts on EF4 How to stop your dba having a heart attack with EF4 from Simon Sabin in the UK. This includes ppt and demos. And the biggy. You no longer have to depend on SQL Profiler to keep an eye on the generated SQL. There is now a commercial profiler for Entity Framework.  I am yet to try it – but I listened to a .NET rocks podcast which made it sound great. It is “hidden” in a session on DSLs in Boo –> Oren Eini on creating DSLs in Boo. This is a much richer experience than you would get from SQL Profiler – matching the SQL to the .NET code. And finally a momentous #fail to … drum roll… the Visual Studio 2010 and .NET Framework 4 Training Kit Feb release. This just contains one ppt on EF4 – and it is not even a good one. Real shame. P.S. I will update the 101 EF4 Resources with the above … but post devweek in case I find some more goodies. Related Links 101 EF4 Resources

  • CodePlex learns to talk to other services!

    CodePlex is now able to talk to other services! For example, if you want CodePlex to tell Trello to update cards on your Trello board, it can do it. Or if you want CodePlex to notify your Campfire chat room when updates are pushed, it can do that too. To start off, we are going to be adding support for the following services: Campfire – Notify a Campfire chat room when commits occur HipChat – Notify a HipChat chat room when commits occur Trello – Add commit summaries to Trello cards by referencing those cards in commit messages Twitter – Notify your Twitter followers when updates are pushed to your project In addition, we will continue to support our existing integrations with Windows Azure – Continuously deploy to Windows Azure on pushes (For Git and Hg projects) AppHarbor – Continuously deploy to AppHarbor on pushes To set up these integrations for your project, navigate to the project settings page as a project coordinator, and click on the services section as seen below:   While we are starting with these six services, the infrastructure is now in place to allow us to quickly roll out new integrations. We would love to hear which services and integrations you would like to see most on our suggestions page. We realize that there are some services and URLs that only make sense for your project to send notifications to. To support this scenario, we plan to add generic web hooks in the near future. Have ideas on how to improve CodePlex? Please visit our suggestions page! Vote for existing ideas or submit a new one. As always you can reach out to the CodePlex team on Twitter @codeplex or reach me directly @Rick_Marron.

  • Using jQuery.UI CSS Framework for DIV Styling

    - by Gordon
    Hi folks, a Project I am currently working on uses the jQuery UI framework for some of its widgets. To provide the user with a global look and feel I would like to use the framework also for its css stuff. I am implementing at the moment a dashboard like homepage, where the user can see an overall status of its data. This dashboard is build of some divs that should be aligned into a grid layout. I try to style the divs like follows <div class="ui-widget"> <div class="ui-widget-header">Box Header</div> <div class="ui-widget-content"> Content of the Box </div> </div> Later I would like to implement some draggable-and-sortable functionality. The Problem I am facing right now is that the boxes aren't properly aligned. Does anyone has a hint on using jQuery.UI for that kind of css work? I was studing the CSS framework documentation on jqueryui.com but there aren't that much information. best regards, Gordon

  • WCF Services (with RIA)

    - by netlogging
    I am new to WCF and WCF derived services. I am using VS 2010, silverlight 4, ria services 4. Recently I created plain WCF REST services (no RIA, no SOAP) with my endpoint (using wsHttpBinging): <endpoint address="" behaviorConfiguration="wsBehavior" binding="wsHttpBinding" bindingConfiguration="wsbinding" contract="WcfService1.IService1"/> <behaviors> <endpointBehaviors> <behavior name="wsBehavior"> <webHttp/> </behavior>......... I use this service from silverlight 4 client and everything works fine. THEN, i created new project using "silverlight Business application" template which used RIA service. Now the web.config uses DomainServices and when i add wsHttpBind endpoint I doesnot work. I know i am not doing this correctly and i cant find any help online so far. What I am trying to do is creat a RESTful WCF application with RIA (no SOAP) and that i can use from silverlight 4 client. For some reason i cannot get the service working.

  • Customize a WCF RIA Services Endpoint

    - by Andrew Garrison
    Is it possible to customize the parameters of a WCF RIA Services endpoint? Specifically, I would like to create a custom binding for the endpoint and increase the maxReceivedMessageSize to allow sending the contents of a file that is a few megabytes in size. I've tried meddling in the web.config, but I'm getting the following error: [InvalidOperationException]: The contract name MyNamespace.MyService could not be found in the list of contracts implemented by the service MyNamespace.MyService web.config <system.serviceModel> <bindings> <customBinding> <binding name="CustomBinaryHttpBinding"> <binaryMessageEncoding /> <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" /> </binding> </customBinding> </bindings> <services> <service name="MyNamespace.MyService"> <endpoint address="" binding="wsHttpBinding" contract="MyNamespace.MyService" /> <endpoint address="/binary" binding="customBinding" bindingConfiguration="CustomBinaryHttpBinding" contract="MyNamespace.MyService" /> </service> </services> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> </system.serviceModel>

  • Converting a Linq expression tree that relies on SqlMethods.Like() for use with the Entity Framework

    - by JohnnyO
    I recently switched from using Linq to Sql to the Entity Framework. One of the things that I've been really struggling with is getting a general purpose IQueryable extension method that was built for Linq to Sql to work with the Entity Framework. This extension method has a dependency on the Like() method of SqlMethods, which is Linq to Sql specific. What I really like about this extension method is that it allows me to dynamically construct a Sql Like statement on any object at runtime, by simply passing in a property name (as string) and a query clause (also as string). Such an extension method is very convenient for using grids like flexigrid or jqgrid. Here is the Linq to Sql version (taken from this tutorial: http://www.codeproject.com/KB/aspnet/MVCFlexigrid.aspx): public static IQueryable<T> Like<T>(this IQueryable<T> source, string propertyName, string keyword) { var type = typeof(T); var property = type.GetProperty(propertyName); var parameter = Expression.Parameter(type, "p"); var propertyAccess = Expression.MakeMemberAccess(parameter, property); var constant = Expression.Constant("%" + keyword + "%"); var like = typeof(SqlMethods).GetMethod("Like", new Type[] { typeof(string), typeof(string) }); MethodCallExpression methodExp = Expression.Call(null, like, propertyAccess, constant); Expression<Func<T, bool>> lambda = Expression.Lambda<Func<T, bool>>(methodExp, parameter); return source.Where(lambda); } With this extension method, I can simply do the following: someList.Like("FirstName", "mike"); or anotherList.Like("ProductName", "widget"); Is there an equivalent way to do this with Entity Framework? Thanks in advance.

  • copy a text file in C#

    - by melt
    I am trying to copy a text file in an other text file line by line. It seems that there is a buffer of 1024 character. If there is less than 1024 character in my file, my function will not copie in the other file. Also if there is more than 1024 character but less a factor of 1024, these exceeding characters will not be copied. Ex: 2048 character in initial file - 2048 copied 988 character in initial file - 0 copied 1256 character in initial file - 1024 copied Thks! private void button3_Click(object sender, EventArgs e) { // écrire code pour reprendre le nom du fichier sélectionné et //ajouter un suffix "_poly.txt" string ma_ligne; const int RMV_CARCT = 9; //délcaration des fichier FileStream apt_file = new FileStream(textBox1.Text, FileMode.Open, FileAccess.Read); textBox1.Text = textBox1.Text.Replace(".txt", "_mod.txt"); FileStream mdi_file = new FileStream(textBox1.Text, FileMode.OpenOrCreate,FileAccess.ReadWrite); //lecture/ecriture des fichiers en question StreamReader apt = new StreamReader(apt_file); StreamWriter mdi_line = new StreamWriter(mdi_file, System.Text.Encoding.UTF8, 16); while (apt.Peek() >= 0) { ma_ligne = apt.ReadLine(); //if (ma_ligne.StartsWith("GOTO")) //{ // ma_ligne = ma_ligne.Remove(0, RMV_CARCT); // ma_ligne = ma_ligne.Replace(" ",""); // ma_ligne = ma_ligne.Replace(",", " "); mdi_line.WriteLine(ma_ligne); //} } apt_file.Close(); mdi_file.Close(); }

  • Latex: Text cannot be placed below image

    - by Frederik Wordenskjold
    I love latex! But sometimes, it does not love me... I'm having a problem with an image and some text. I have this code: Some text...\\ \begin{figure}[ht] \centering \includegraphics[scale=0.75]{picture.jpg} \caption{The caption} \label{fig:picture} \end{figure} Some more text... Basically, I want this: Some text. (Above image in the code) [end of page / new page] image Some more text. (Below the image in the code) [start of new section] But, what the above code gives me is this: Some text. (Above image in the code) Some more text. (Below the image in the code) [end of page / new page] image [start of new section] Latex insists on putting everything but a new section above the image even though its below the image in the code. Its probably because the image floats on top - but whats my alternative? There's not enough space on the first page to display the image there, to I cannot use [h] as the float-alignment. I can "hack it", by creating an empty new section, like \section*{}, but this creates some white-space, which looks weird. Any suggestions?

  • What java web application framework to use?

    - by frohiky
    One of the main products of my company is an Oracle Forms (and Reports) based application, that "needs" to be re-written in another technology. Why? Users want a more rich interface experience, and we want, preferably, to reduce costs with an open source application server. For this (HUGE) project, we intend to use a java web application framework, keep these points in mind: We have: hundreds of tables on our database (the ORM must be as flexible as possible); some logic which is (and will still be) based on PL/SQL procedures/functions/packages; a lot of CRUDs (the application itself is of an considerable size); a demand to work with/generate documents and workflows; an intranet based user environment; We want: to offer a RIA interface experience; use (if possible) an open source app server; a rapid (as possible) development framework; a somewhat mature framework with a "wise" roadmap (and a considerable community support); a MVC approach combined with JS or GWT widgets (e.g. Vaadin or SmartGWT); Well, in the past weeks I've read a lot of posts, Q&As on stackoverflow, and much more: Wicket, JSF, Tapestry, Grails, GWT, Struts2, Play, Spring, Seam, Echo, .... the list goes on! I've even researched about Alfresco..! The obvious question: Which one to use? At this time, any insight, recommendation, shared experience, advice will be more then welcome!

  • Clearing input text feilds when clicked on in Flash (AS 2.0)

    - by rickstyphilis
    I have a problem where I want a text field that by default has the word NAME in it, to become empty when a user clicks on it. The text field has the instance name 'nam' and is inside a movie with the instance name 'input_text'. I've searched around and found samples of code where everyone keeps suggesting this: textboxinstancename.onSetFocus = function() { textboxinstancename.text = ""; }; should work. It seems to work for everyone else but me. I've tried using the following on the first frame of the 'input_text' movie with no luck: this.input_text.nam.onSetFocus = function() { this.input_text.nam.text = "" } I've tried putting this on the first frame of the scene, again with no result: _root.input_text.nam.onSetFocus = function() { _root.input_text.nam.text = "" } I've tried this in the same manner as the last respectively with both 'this' on the instance and '_root' on the scene (denoted by x): x.input_text.nam.onSetFocus = function() { if (x.input_text.nam.text == "NAME") { x.input_text.nam.text = ""; } }; Still no luck. Can anyone tell me what I might be doing wrong?

  • What is the PastryKit Framework?

    - by Kerrick
    I'm trying to find any information I can on the PastryKit Javascript Framework. It appears to be in use on the iPhone User Guide that is displayed on the iPhone itself in Mobile Safari, but I cannot find any documentation or API. If you want to see it in action, open Safari 4, set your user agent to iPhone 3 (In the Develop menu) and check out the guide. Overall, it seems to be a way to write an HTML/CSS/Javascript application that acts like a native iPhone app. When it comes to Javascript, I used the JS Beautifier on (what I assume to be) the framework file and it was over 3,400 lines! Beautified, (again what I assume to be) their implementation of it was over 1,200 lines. On the CSS side, I used Clean CSS on (again what I assume to be) the framework CSS, and it came out to over 700 lines. Their implementation was shy of 500. Does anybody have, or know where to find, any information, documentation, or APIs on PastryKit? Or, can anybody figure out how to implement it?

  • Advice Please: SQL Server Identity vs Unique Identifier keys when using Entity Framework

    - by c.batt
    I'm in the process of designing a fairly complex system. One of our primary concerns is supporting SQL Server peer-to-peer replication. The idea is to support several geographically separated nodes. A secondary concern has been using a modern ORM in the middle tier. Our first choice has always been Entity Framework, mainly because the developers like to work with it. (They love the LiNQ support.) So here's the problem: With peer-to-peer replication in mind, I settled on using uniqueidentifier with a default value of newsequentialid() for the primary key of every table. This seemed to provide a good balance between avoiding key collisions and reducing index fragmentation. However, it turns out that the current version of Entity Framework has a very strange limitation: if an entity's key column is a uniqueidentifier (GUID) then it cannot be configured to use the default value (newsequentialid()) provided by the database. The application layer must generate the GUID and populate the key value. So here's the debate: abandon Entity Framework and use another ORM: use NHibernate and give up LiNQ support use linq2sql and give up future support (not to mention get bound to SQL Server on DB) abandon GUIDs and go with another PK strategy devise a method to generate sequential GUIDs (COMBs?) at the application layer I'm leaning towards option 1 with linq2sql (my developers really like linq2[stuff]) and 3. That's mainly because I'm somewhat ignorant of alternate key strategies that support the replication scheme we're aiming for while also keeping things sane from a developer's perspective. Any insight or opinion would be greatly appreciated.

  • Alternatives to the Entity Framework for Serving/Consuming an OData Interface

    - by Egahn
    I'm researching how to set up an OData interface to our database. I would like to be able to pull/query data from our DB into Excel, as a start. Eventually I would like to have Excel run queries and pull data over HTTP from a remote client, including authentication, etc. I've set up a working (rickety) prototype so far, using the ADO.NET Entity Data Model wizard in Visual Studio, and VSTO to create a test Excel worksheet with a button to pull from that ADO.NET interface. This works OK so far, and I can query the DB using Linq through the entities/objects that are created by the ADO.NET EDM wizard. However, I have started to run into some problems with this approach. I've been finding the Entity Framework difficult to work with (and in fact, also difficult to research solutions to, as there's a lot of chaff out there regarding it and older versions of it). An example of this is my being unable to figure out how to set the SQL command timeout (as opposed to the HTTP request timeout) on the DataServiceContext object that the wizard generates for my schema, but that's not the point of my question. The real question I have is, if I want to use OData as my interface standard, am I stuck with the Entity Framework? Are there any other solutions out there (preferably open source) which can set up, serve and consume an OData interface, and are easier to work with and less bloated than the Entity Framework? I have seen mention of NHibernate as an alternative, but most of the comparison threads I've seen are a few years old. Are there any other alternatives out there now? Thanks very much!

  • Entity Framework and associations between string keys

    - by fredrik
    Hi, I am new to Entity Framework, and ORM's for that mather. In the project that I'm involed in we have a legacy database, with all its keys as strings, case-insensitive. We are converting to MSSQL and want to use EF as ORM, but have run in to a problem. Here is an example that illustrates our problem: TableA has a primary string key, TableB has a reference to this primary key. In LINQ we write something like: var result = from t in context.TableB select t.TableA; foreach( var r in result ) Console.WriteLine( r.someFieldInTableA ); if TableA contains a primary key that reads "A", and TableB contains two rows that references TableA but with different cases in the referenceing field, "a" and "A". In our project we want both of the rows to endup in the result, but only the one with the matching case will end up there. Using the SQL Profiler, I have noticed that both of the rows are selected. Is there a way to tell Entity Framework that the keys are case insensitive? Edit:We have now tested this with NHibernate and come to the conclution that NHibernate works with case-insensitive keys. So NHibernate might be a better choice for us.I am however still interested in finding out if there is any way to change the behaviour of Entity Framework.

  • jQuery display text nested in paragraphs inside a div

    - by user961627
    I have HTML that looks something like this: <div class='textbox' data-title='Sometitle'> <div class='textareaedit'> <p><strong>Test sample text</strong></p> </div> </div> I'm sometimes going to have a few different <p> tags inside the textareaedit divs, and sometimes strong tags around the text inside the <p> (as in this example), and sometimes a span tag, and sometimes it's going to be without further tags inside the <p>. I want to iterate through each textbox on my page, grab its title and also the text nested inside <p> tags in textareaedit. I'm giving the output via console for testing. This is my jQuery code, but I get no output for the second console.log() line: $('.textbox').each(function() { $this = $(this); console.log($this.attr('data-title')+ ":\n"); $this.children('textareadit').children('p').each(function(){ console.log($(this).html()); // not giving any output, it's blank }); }); I tried $(this).text() as well, but no difference. You may think this example has the sample text inside <strong> tags within the <p>, but I've also tried the same example without the strong, where the text was the direct child of <p>, but it didn't make a difference. How can I capture the text?

  • SIMPLE PHP MVC Framework [closed]

    - by Allen
    I need a simple and basic MVC example to get me started. I don't want to use any of the available packaged frameworks. I am in need of a simple example of a simple PHP MVC framework that would allow, at most, the basic creation of a simple multi-page site. I am asking for a simple example because I learn best from simple real world examples. Big popular frameworks (such as code igniter) are to much for me to even try to understand and any other "simple" example I have found are not well explained or seem a little sketchy in general. I should add that most examples of simple MVC frameworks I see use mod_rewrite (for URL routing) or some other Apache-only method. I run PHP on IIS. I need to be able to understand a basic MVC framework, so that I could develop my own that would allow me to easily extend functionality with classes. I am at the point where I understand basic design patterns and MVC pretty well. I understand them in theory, but when it comes down to actually building a real world, simple, well designed MVC framework in PHP, I'm stuck. Edit: I just want to note that I am looking for a simple example that an experienced programmer could whip up in under an hour. I mean simple as in bare bones simple. I don't want to use any huge frameworks, I am trying to roll my own. I need a decent SIMPLE example to get me going.

  • Entity Framework POCO objects

    - by Dan
    I'm struggling with understanding Entity Framework and POCO objects. Here's what I'm trying to achieve. 1) Separate the DAL from the Business Layer by having my business layer use an interface to my DAL. Maybe use Unity to create my context. 2) Use Entity Framework inside my DAL. I have a Domain model with objects that reside in my business layer. I also have a database full of tables that doesn't really represent my domain model. I setup Entity Framework and generated POCO objects by using the ADO.NET POCO Generator extension. This gave me an object for each table in my database. Now I want to be able to say context.GetAll<User>(); and have it return a list of my User objects. The User object is in my business layer. Is that possible? Does that make sense or am I totally off and should start over? I'm guessing I need to use the repository pattern to achieve this, but I'm not sure. Can anyone help?

  • [PHP/MySQL] How to create text diff web app

    - by Adam Kiss
    Hello, idea I would like to create a little app for myself to store ideas (the thing is - I want it to do MY WAY) database I'm thinking going simple: id - unique id of revision in database text_id - identification number of text rev_id - number of revision flags - various purposes - expl. later title - self expl. desc - description text - self expl . flags - if I (i.e.) add flag rb;65, instead of storing whole text, I just said, that whenever I ask for latest revision, I go again in DB and check revision 65 Question: Is this setup the best? Is it better to store the diff, or whole text (i know, place is cheap...)? Does that revision flag make sense (wouldn't it be better to just copy text - more disk space, but less db and php processing. php I'm thinking, that I'll go with PEAR here. Although main point is to open-edit-save, possiblity to view revisions can't be that hard to program and can be life-saver in certain situations (good ideas got deleted, saving wrong version, etc...). However, I've never used PEAR in a long-time or full-project relationship, however, brief encounters in my previous experience left rather bad feeling - as I remember, it was too difficult to implement, slow and humongous to play with, so I don't know, if there's anything better. why? Although there are bazillions of various time/project/idea management tools, everything lacks something for me, whether it's sharing with users, syncing on more PCs, time-tracking, project management... And I believe, that this text diff webapp will be for internal use with various different tools later. So if you know any good and nice-UI-having project management app with support for text-heavy usage, just let me know, so I'll save my time for something better than redesigning the weel.

  • Read huge free text docs in one file for lucene indexing

    - by Jun
    I have heaps of free text news docs in one big file. The structure of each news doc is like: (Header line) Category, Doc1, Date (day, month, year) (body text) ... ... ... (Header line) Category, Doc2, Date (day, month, year) (body text) ... ... ... If I extract each doc from the big file, it costs too much time and not efficient. Therefore, I decide to read the file line by line and feed information to lucene the same time. I write c# code to index each doc to lucene like: Streamreader sr = new Streamreader(file); string line = ""; while((line = sr.ReadLine()) != null) { How can I tell this line is a doc header line from text line and get the metadata and all the text lines of a doc for lucene to index. Also, the text is read by OCR which can not give correct line-separating. Captions are mixed with content text iterate the process till the end of the file } with thanks

    How can I "bulk paste" a clipboard string of multi-line text into a readable ordered list? I'm trying to demonstrate how to turn any string of multi-line text into an ordered list. The script (preferably JS) needs to respect: - carriage returns at the end of a line, to mean "that line ends here" - indentations at the beginning of a line, to mean "this is part of the item above it" - dashes at the beginning of a line, to mean "this is a task, and the line above it is its project"

  • jQuery textbox required validation based on another text box having text

    - by doug
    Pretty basic question, however, I am very new to jQuery and javascript in general. I have a jQuery validation that is requiring a text box to have text in it, if a checkbox is checked. <script type="text/javascript"> $(document).ready(function () { $("form").validate( { rules: { Comments: { required: "#IsAbnormal:checked" } }, messages: { Comments: { required: "Comments are required" } }, onkeyup: false, wrapper: "", errorLabelContainer: "#ErrorMessageBox" }); }); Pretty straight forward, if you check the IsAbnormal checkbox, it will throw a validation if there are no comments. What I am trying to do is require a textbox based on if another text box has any text in it, for instance require the old password if a user enters a new password into a textbox. Is there an easy way to get the required: "#NewPassword:NotBlank" to work?

  • Best practices: displaying text that was input via multi-line text box

    - by chris
    I have a multi-line text box. When users simply type away, the text box wraps the text, and it's saved as a single line. It's also possible that users may enter line breaks, for example when entering a "bulleted" lists like: Here are some suggestions: - fix this - remove that - and another thing Now, the problem occurs when I try to display the value of this field. In order to preserve the formatting, I currently wrap the presentation in <pre> - this works to preserve user-supplied breaks, but when there's a lot of text saved as a single line, it displays the whole text block as single line, resulting in horizontal scrolling being needed to see everything. Is there a graceful way to handle both of these cases?
