  • Is there a codeigniter api reference?

    - by ajsie
    whenever using a framework it's so good with a api reference so you could lookup the classes' methods and properties, which class they extend from and so on. is there a api reference for codeigniter similar to yii's excellent api referenc? http://www.yiiframework.com/doc/api/ how else could you know more about the details about the classes if there isn't a good api reference. java's api reference is also great: http://java.sun.com/j2se/1.4.2/docs/api/ why can't i find codeigniter's. thanks.

  • What is The Loop Variable After a For Loop in Delphi?

    - by Andreas Rejbrand
    In Delphi, consider var i: integer; begin for i := 0 to N do begin { Code } end; One might think that i = N after the for loop, but does the Delphi compiler guarantee this? Can one make the assumption that the loop variable is equal to its last value inside the loop, after a Delphi if loop? Update After trying a few simple loops, I suspect that i is actually equal to one plus the last value of i inside the loop after the loop... But can you rely on this?

  • Does the order of readonly variable declarations guarantee the order in which the values are set?

    - by Jason Down
    Say I were to have a few readonly variables for filepaths, would I be able to guarantee the order in which the values are assigned based on the order of declaration? e.g. readonly string basepath = @"my\base\directory\location"; readonly string subpath1 = basepath + @"\abc\def"; readonly string subpath2 = basepath + @"\ghi\klm"; Is this a safe approach or is it possible that basepath may still be the default value for a string at the time subpath1 and subpath2 make a reference to the string? I realize I could probably guarantee the order by assigning the values in a constructor instead of at the time of declaration. However, I believe this approach wouldn't be possible if I needed to declare the variables inside of a static class (e.g. Program.cs for a console application, which has a static void Main() procedure instead of a constructor).

  • How to get a variable name as a string in Python?

    - by e-satis
    I would like to be able to get the name of a variable as a string but I don't know if Python has that much introspection capabilities. Something like: >>> print(my_var.__name__) 'my_var' I want to do that because I have a bunch of vars I'd like to turn into a dictionary like : bar=True foo=False >>> my_dict=dict(bar=bar, foo=foo) >>> print mydict >>> print my_dict {'foo': False, 'bar': True} But I'd like something more automatic than that. Python have locals() and vars(), so I guess there is a way.

  • Bind Variable and SQL error during statement preparation

    - by Abhishek Dwivedi
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}  I was getting the following exception at run-time. JBO-27122: SQL error during statement preparation. Statement: SELECT AxEO.A_ID, AxEO.B_ID, AxEO.C_ID, ByEO.A_ID, ByEO.B_ID, ByEO.C_ID, Cz.A_ID, Cz.B_ID, Cz.C_ID FROM ABC_x AxEO, ABC_y ByEO, ABC_z CzEO WHERE AxEO.A_ID = ByEO.A_ID AND  CzEO.A_ID = :Bind_PId I copied and pasted the query on SQL worksheet, replaced :Bind_PId with a valid id, and executed the query. The query worked alright, implying the query was alright. I tried to connect to different DBs but the issue persisted, meaning it was not a DB issue either. Finally, the root cause was found to be in the concerned VO; one of the bind variables (say Bind_TId) was marked "Required". De-selecting the Required check-box resolved the issue. In retrospect, the issue looks to be rather straight-forward. However, the error message is not very helpful, if not misleading. Besides, it's counter-intuitive to think that a bind variable which is not being used in a query can cause error while statement preparation. The other bind variable - Bind_TId - was being used in other view criteria, not the view criteria involved in the given query. Still, it was required.

  • Meta package / quick reference for string manipulation commands?

    - by Dylan McCall
    The latest version of the Scribes text editor lets us select some text, hit Alt+X, and then run an arbitrary command. For example, I can run the sort command and the selected text is replaced appropriately. This is quite useful but I am also not very well-versed in awk and the like. Is there something I can grab that will provide more of these commands like sort? Maybe a package with a whole bunch of handy, task-specific string manipulation commands?

  • Introducing the Oracle Parcel Service&ndash;Example/Reference Application

    - by Jeffrey West
    Over the last few weeks the product management team has been working on a webcast series that is airing in EMEA.  It is a 5-episode series where we talk about different features of WebLogic and show how to build applications that take advantage of these features.  Each session is focused at a different layer of the technology stack, and you can find the schedule below. The application we are building in this series is named the ‘Oracle Parcel Service’.  It is an example application and not a product of Oracle by any stretch of the imagination.  Over the next few weeks we will be finalizing the code and will be releasing it for you to check out.  For updates, request membership to the Oracle Parcel Service project on SampleCode.oracle.com: https://www.samplecode.oracle.com/sf/projects/oracle-parcel-svc/. Here are some of the key features that we are highlighting: JPA 2.0 (new in WebLogic 10.3.4) with EclipseLink Coherence TopLink Grid Level 2 cache for JPA JAX-RS (new in WebLogic 10.3.4) 1.0 for RESTful services Lightweight JQuery Web UI for consuming RESTful services JSF 2.0 (new in WebLogic 10.3.4) utilizing PrimeFaces EJB 3.0 Spring-WS Web Services JAX-WS Web Services Spring MDP’s for Event Driven Architectures Java MDB’s for Event Driven Architectures Partitioned Distributed Topics for Event Driven Architectures   Accessing the Code on SampleCode.Oracle.com You will need to log in using your Oracle.com username and password.  If you have not created an account, you will need to do so.  It’s a simple one-page form and we don’t bother you with too many emails.   Please join the project to be kept up to date on changes to the code and new projects.  Joining the project is not required, but very much appreciated. Once you have signed in you should see an icon for accessing the Source Code via Subversion.  You can also download a zip file containing the code.

  • Open source engagement as a professional reference

    - by Martin
    if one commits his or her time to an open source project, he or she may be invest a substantial amount of time without getting paid. As much as altruism is appreciable, I wonder whether it "counts" as an activity which can be shown and is valued in job applications. If the company is worth your time and working power, which it should be in my honest opinion. So I wonder whether there is something like a common practice in open source projects for this matters. Say, something like Mr. Martin has been working on our project for five years and has contributed this and that,[...] I we wish him very best for his future. Mr. ChiefofProject I think this is a just concern. Do have experiences you can share?

  • How to reference jQuery in SharePoint2010

    - by ybbest
    In normal asp.net development, in order to add jQuery to your solution you need to add the following script to your Master page. <script language=”javascript” type=”text/javascript” src=”Scripts/jquery-1.4.1.min.js”></script> There are not many differences in referencing jQuery in SharePoint2010; in fact you got quite a few ways to achieve this. The first thing you need to do is to deploy jQuery using SharePoint module template in Visual studio. Then you can choose one of the following ways of referencing jQuery. 1. Using a Delegate Control 2. in the master Page 3. Ad hoc (e.g. in a site page or web part) 4. Using a Custom Action (Can be used as Sandbox solution, you can find example here.) References: jquery How to bootstrap JQuery on every SharePoint page, even in the Sandbox Referencing Javascript Files with SharePoint 2010 Custom Actions using SciptSrc

  • Where and how to reference composite MVP components?

    - by Lea Hayes
    I am learning about the MVP (Model-View-Presenter) Passive View flavour of MVC. I intend to expose events from view interfaces rather than using the observer pattern to remove explicit coupling with presenter. Context: Windows Forms / Client-Side JavaScript. I am led to believe that the MVP (or indeed MVC in general) pattern can be applied at various levels of a user interface ranging from the main "Window" to an embedded "Text Field". For instance, the model to the text field is probably just a string whereas the model to the "Window" contains application specific view state (like a persons name which resides within the contained text field). Given a more complex scenario: Documentation viewer which contains: TOC navigation pane Document view Search pane Since each of these 4 user interface items are complex and can be reused elsewhere it makes sense to design these using MVP. Given that each of these user interface items comprises of 3 components; which component should be nested? where? who instantiates them? Idea #1 - Embed View inside View from Parent View public class DocumentationViewer : Form, IDocumentationViewerView { public DocumentationViewer() { ... // Unclear as to how model and presenter are injected... TocPane = new TocPaneView(); } protected ITocPaneView TocPane { get; private set; } } Idea #2 - Embed Presenter inside View from Parent View public class DocumentationViewer : Form, IDocumentationViewerView { public DocumentationViewer() { ... // This doesn't seem like view logic... var tocPaneModel = new TocPaneModel(); var tocPaneView = new TocPaneView(); TocPane = new TocPanePresenter(tocPaneModel, tocPaneView); } protected TocPanePresenter TocPane { get; private set; } } Idea #3 - Embed View inside View from Parent Presenter public class DocumentationViewer : Form, IDocumentationViewerView { ... // Part of IDocumentationViewerView: public ITocPaneView TocPane { get; set; } } public class DocumentationViewerPresenter { public DocumentationViewerPresenter(DocumentationViewerModel model, IDocumentationViewerView view) { ... var tocPaneView = new TocPaneView(); var tocPaneModel = new TocPaneModel(model.Toc); var tocPanePresenter = new TocPanePresenter(tocPaneModel, tocPaneView); view.TocPane = tocPaneView; } } Some better idea...

  • Harry Foxwell talks about "Oracle Solaris 11 System Administration: The Complete Reference"

    - by Glynn Foster
    In a previous blog entry, New Oracle Solaris 11 Administration book, I blogged about the fact that a new book has been written to provide an excellent resource for administrators starting to learn some of the new features in Oracle Solaris 11. Despite an extensive set of online resources from the Oracle Technology Network, it's also useful to have something in the bookshelf that you can quickly refer to - and Harry Foxwell and his team of co-authors have done just that. Check out the video below where Harry goes into detail about why the book was written, details about the target audience, and what he's excited about in Oracle Solaris 11. Best of all though, is the fact that this is a brilliant book for any inspiring Linux administrator who wants to start getting to know the Oracle Solaris operating system a little better.

  • Help, i cant reference my vars!

    - by SystemNetworks
    I have a sub-class(let's call it sub) and it contains all the function of an object in my game. In my main class(Let's call it main), i connect my sub to main. (Example sub Code: s = new sub(); Then I put my sub function at the update method. Code: s.myFunc(); Becuase in my sub, i have booleans, integers, float and more. The problem is that I don't want to connect my main class to use my main's int, booleans and others. If i connect it, it will have a stack overflow. This is what I put in my sub: Code: package javagame; import org.newdawn.slick.GameContainer; import org.newdawn.slick.Graphics; import org.newdawn.slick.Input; import org.newdawn.slick.state.StateBasedGame; public class Armory { package javagame; import org.newdawn.slick.GameContainer; import org.newdawn.slick.Graphics; import org.newdawn.slick.Input; import org.newdawn.slick.state.StateBasedGame; public class Store { public Integer wood; public Float probePositionX; public Float probePositionY; public Boolean StoreOn; public Boolean darkBought; public Integer money; public Integer darkEnergy; public Integer lifeLeft; public Integer powerLeft; public void darkStores(GameContainer gc, StateBasedGame sbg, GameContainer gc2) { Input input1 = gc.getInput(); //Player need wood to enter(200) If not there will be an error. if(wood>=200) { //Enter Store! if(input1.isKeyDown(Input.KEY_Q)) { //Player must be in this cord! if((probePositionX>393 && probePositionX<555) && (probePositionY< 271 && probePositionY>171)) { //The Store is On StoreOn=true; } } } } } In my main (update function) I put: Code: s.darkBought = darkBought; s.darkEnergy = darkEnergy; s.lifeLeft = lifeLeft; s.money = money; s.powerLeft = powerLeft; s.probePositionX = probePositionX; s.probePositionY = probePositionY; s.StoreOn = StoreOn; s.wood = wood; s.darkStores(gc, sbg, gc); The problem is when I go to the place, and I press q, nothing shows up. It should show another image. Is there anything wrong???

  • Parent variable inheritance methods Unity3D/C#

    - by Timothy Williams
    I'm creating a system where there is a base "Hero" class and each hero inherits from that with their own stats and abilities. What I'm wondering is, how could I call a variable from one of the child scripts in the parent script (something like maxMP = MP) or call a function in a parent class that is specified in each child class (in the parent update is alarms() in the child classes alarms() is specified to do something.) Is this possible at all? Or not? Thanks.

  • Session and Cache are By Reference

    Recently a colleague remarked that if he got a List of some type out of the ASP.NET Cache, and changed an item, the Cache item would also change.That is correct. Session (InProc) , Cache and Application all return "live" references. A good writeup on this can be found by friend and fellow MVP Rick Strahl here:http://www.west-wind.com/Weblog/posts/1214.aspxIf you do not want this behavior, you need to either delete the Session / Cache / Application object and replace it with what you want later, or...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?
