• Load a controller into an other controller in cakephp

  - by john

  im developing a web application, using multiple pages, each with their own controller. The problem now is that there are some variables in a controller, created for one page, that are required for an other page ( with a different controller). Therefor i need to load one controller into the other one. I did this by adding App::import('Controller', 'sections'); $sections= new sectionsController; $sections-constructClasses(); to the controller, but this doens't seem to work.. Maybe u guys have some ideas? Thnx in advance!

• From interpeted to native code: "dynamic" languages compiler support

  - by Daniel

  First, I am aware that dynamic languages is a term used mainly by a vendor; I am using it just to have a container word to include languages like Perl (a favorite of mine), Python, Tcl, Ruby, PHP and so on. They are interpreted but I am interested here to refer to languages featuring strong capability to support the programmer efficiency and the support for typical constructs of modern interpreted languages My question is: there are dynamic languages can be compiled efficiently in native executable code - typically for Windows platforms? Which ones? Maybe using some third part ad-hoc tools? I am not talking about huge executables carrying with them a full interpreter or some similar tricks nor some smart module able to include its own dependances or some required modules, but a honest, straight, standard, solid executable code. If not, there is some technical reason inhibiting the availability of such a best-of-both-world feature? Thanks! Daniel

• Constructing T-SQL WHERE condition at runtime

  - by Nickson

  I would like to implement a search function where a user passes all the arguments to the "WHERE" clause at runtime. For example in query below, SELECT Col1, Col2, Col3, Col4 FROM MyTable WHERE Col2 = John 1.Now what i want is to give the user a dropdownlist of columnns such that the user selects a column to search by at runtime Also instead of precoding Col2 = John, i want the user to choose their own operator at runtime(such as choosing between =, <, <, <, LIKE, IN) i basically want to contruct a query like SELECT Col1, Col2, Col3, Col4 FROM MyTable WHERE (@FieldToSearchBy e.g Col3, @OperatorToUserInSearach e.g LIKE, @ValueToSearch e.g John) I want to pass @FieldToSearchBy, @OperatorToUserInSearach, @ValueToSearch) as user specified parameters at runtime I want to do this with a TableAdpter like in this example http://www.codeproject.com/KB/database/TableAdapter.aspx

• codemirror fails when adding </textarea> tag inside it

  - by Jorre

  I'm using codemirror http://marijn.haverbeke.nl/codemirror/ to let users create their own web templates inside a web application. Codemirror works great, except for the time that users have put a tag inside their source code. When I load that up inside code mirror, it breaks everything in the source code that follows after because it thinks my codemirror text area is closed. I'm using the following way to launch codemirror: CodeMirror.fromTextArea('code') It works great on my existing textarea "code" except when users add inside their templates (in the codemirror textarea). Any help is much appreciated!

• How to use MOV instruction in ARM with an immediate number as the second operand

  - by Summer_More_More_Tea

  Hi everyone: I just begin to study ARM assembly language, and am not clear about how to use MOV to transfer an immediate number into a register. From both the ARM reference manual and my textbook, it's said that range of immediate number following MOV instruction is 0-255. But when I test on my own PC in ADS 1.2 IDE, instruction MOV R2, #0xFFFFFFFF performs well. Isn't number 0xFFFFFFFF out of range according to the specification? Hope someone can give me a hand. Regards.

• Alternative approach to OpenGL View on top of Camera

  - by Mr. Roland

  Hi, the traditional way of doing a camera preview background with OpenGL on the front is to take two SurfaceViews(one for the camera another for OpenGL) and stack them on top of each other. The problem is that stacking SurfaceViews is discouraged: http://groups.google.com/group/android-developers/browse_thread/thread/4850fe5c314a3dc6 So what alternatives are there? I was considering the following: Subclass GlSurfaceView, and then call set the Camera preview onto the holder of this subclass: Camera.setPreviewDisplay(mHolder); Don't use GLSurfaceView, instead create your own SurfaceView subclass where you display the Camera preview onto the holder and also draw your openGL. This would require to use OpenGL without GLSurfaceView, has anyone done this before? I'm not sure if this even is possible or makes sense, since it implies displaying the camera preview onto the holder of the surface and at the same time drawing OpenGL on the same surface. Is there any other sensible alternative to solving the problem without using two SurfaceViews? Thanks!

• Fixing javascript Array functions in Internet Explorer (indexOf, forEach, etc)

  - by Chas Emerick

  As detailed elsewhere, and otherwise apparently well-known, Internet Explorer (definitely 7, and in some instances, 8) do not implement key functions, in particular on Array (such as forEach, indexOf, etc). There are a number of workarounds here and there, but I'd like to fold a proper, canonical set of implementations into our site rather than copy and paste or hack away at our own implementations. I've found js-methods, which looks promising, but thought I'd post here to see whether another library comes more highly-recommended. A couple of misc. criteria: the lib should just be a no-op for those functions that a browser already has implementations for (js-methods appears to do quite well here) non-GPL, please, though LGPL is acceptable

• For a .Net project, what file extensions should I exclude from source control?

  - by arame3333

  Everytime I start a project I have to think carefully about which files to exclude from source control. Has someone made a list of the criteria so I can look it up from the beginning? I work on my own so I have not got round to it. I appreciate that in the case of a DLL, you would want to include some and exclude others, so it is not just dependent on the file extension. My projects are ASP.Net, although a general discussion of other templates would also be useful.

• Microsoft Database project requires Visual studio 2010 premium or higher? Are there any open source

  - by skurge

  Hello, I need to know wether or not to buy the VS 2010 premium or not. I have the database project working on my own version of vs 2008 team suite. My coworkers only have 2008 professional. We are moving to VS2010 now. We do not have MSDN licenses for our company right now. We are looking to buy just the VS2010 no MSDN. It is very pricey to get 6 of VS2010 premium. We need to get our database into source control. We are currently email scripts around, and it very difficult to keep track off. Are there any non-microsoft solutions that would be the same features and be free?

• Building a webserver, client doesn't acknowledge HTTP 200 OK frame.

  - by Evert

  Hi there, I'm building my own webserver based on a tutorial. I have found a simple way to initiate a TCP connection and send one segment of http data (the webserver will run on a microcontroller, so it will be very small) Anyway, the following is the sequence I need to go through: receive SYN send SYN,ACK receive ACK (the connection is now established) receive ACK with HTTP GET command send ACK send FIN,ACK with HTTP data (e.g 200 OK) receive FIN,ACK <- I don't recieve this packet! send ACK Everything works fine until I send my acknowledgement and HTTP 200 OK message. The client won't send an acknowledgement to those two packages and thus no webpage is being displayed. I've added a pcap file of the sequence how I recorded it with wireshark. Pcap file: http://cl.ly/5f5 (now it's the right data) All sequence and acknowledgement numbers are correct, checksum are ok. Flags are also right. I have no idea what is going wrong.

• Mysql adapter for Zend_Translate

  - by Peter

  Hi everybody, I'm currently in the planning phase of a rather large project that I'll develop in the Zend Framework. One of the problems I'm facing is that the customers will want to translate not only the content but also the interface. I'm currently using gettext and poedit to manage my language files but this is not an option for the customer as they, for one, want have FTP access to the site. Hence, I'm thinking of a mysql back end with an interface in the front end for the customer to manage his own translations of the interface. There is however still no mysql adapater for Zend_Translate. So, does anybody now of an adapter script for Zend_Translate so it can work with a mysql table? Or any arguments against using mysql and possible other solutions for this problem?

• Auto-Complete Suggestions in Source Code Editor

  - by Jim

  Hello, Most IDEs (Eclipse, Netbeans, Intelij) provide contextually smart suggestions about the current statement you're writing. We would like to do the same thing (In Java for Java). We considered tokenizing the input and building our own abstract syntax trees, but quickly realized that could be a month long project in and of its self. We also started digging through the source code for the above mentioned IDEs, but it appears (correct me if I'm wrong) that the auto-complete code is pretty tightly woven with the rest of the IDE. We're wondering if anyone knows of a relatively isolated package that we could pull into our project to provide this auto-complete functionality. Thanks!

• Why does Excel expose an 'Evaluate' method at all?

  - by jtolle

  A few questions have come up recently involving the Application.Evaluate method callable from Excel VBA. The old XLM macro language also exposes an EVALUATE() function. Both can be quite useful. Does anyone know why the general expression evaluator is exposed, though? My own hunch is that Excel needed to give people a way to get ranges from string addresses, and to get the value of named formulas, and just opening a portal to the expression evaluator was the easiest way. But of course you don't need the ability to evaluate arbitrary expressions just to do that. Application.Evaluate seems kind of...unfinished. It isn't very well documented, and there are quite a few quirks and limitations (as described by Charles Williams here: http://www.decisionmodels.com/calcsecretsh.htm) with what is exposed. I suppose the answer could be simply "why not expose it?", but I'd be interested to know what design decisions led to this feature. Failing that, I'd be interested to hear other hunches.

• Any Way to Further Customize Embedded Google Calendar?

  - by user117737

  I'd like to embed a few Google Calendars for my client's web site. The "Google Embeddable Calendar Helper" provides very few customization options. Updating the hex code for the background color in the generated source only works if you pick one of the ~70 standard Google Calendar bg colors. (I can tweak the "border" selector because at least it's in an actual statement.) A "view-source" on the rendered page shows a CSS file loaded from the iframe, but I obviously can't change anything in there. And I assume I can't force an override of selectors with my own CSS file because I have no way of "injecting" it into the iframe. Does anyone know of a (non-API) way of tweaking the colors, fonts, and other CSS thingies in an embedded Google Calendar? Thanks in advance...

• need identical string comparison function in php and java

  - by steelbytes

  I have sorted list of strings that I move between php and java. to be able to bsearch on this data, I need the same comparison function. any idea what string compare functions I can use that will always give the same result in both? eg php's strcmp() vs java's String.compareTo() yes I know I could make my own string compare that does char by char carefully, but I was hoping there's a simple answer. PS, don't care if case sensitive or not, as long as it is consistant.

• oracle plsql: retrieve runtime parameter values when you call a procedure

  - by Luca Vaccaro

  I need a generalized method to get list of runtime parameters (values) when I call a procedure. I need something similar to the $$PLSQL_UNIT that returns the name of the running procedure. (plsql Oracle 10g) E.g. look at this sample procedure: (it simply prints its own name and parameters ) CREATE OR REPLACE PROCEDURE MY_PROC(ow in varchar2, tn IN varchar2) IS BEGIN dbms_output.put_line('proc_name: '||$$PLSQL_UNIT||' parameters: '|| ow||' '||tn ); EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE('ERRORE: ' ||SQLERRM); END MY_PROC; / Running procedure produces the following output: SQL> 1 BEGIN 2 IBAD_OWN.MY_PROC('first_par', 'second_par'); 3 END; 4 / proc_name: MY_PROC parameters: first_par second_par PL/SQL procedure successfully completed. I'm not satisfy because I can't copy and paste in all my procedures because I have to hard code each procedure to set their right parameter variables. Thanks in advance for the help.

• Will the URL /nosuchpage get routed via my ASP.NET MVC application?

  - by Gary McGill

  [I'm trying to figure out the reason why I'm having another problem, and this question is part of the puzzle.] I have an MVC 2 website that has routing set up so that URLs such as /Customer/23/Order/47 get handled by various controllers. I do not have a rule that would match, for example, /nosuchpage and in my Cassini environment a request for that URL will trigger my Application_Error code, which lets me log the error and show a friendly response. However, when I deployed this website on IIS7 using integrated mode, my Application_Error is not triggered, and IIS shows its own 404 message. No matter what I've tried, I can't get Application_Error to fire. Now I'm thinking: is the reason it doesn't fire because the request is not getting routed via my application? Either because I didn't explicitly set up a catch-all route, or because the file-extension fools it into thinking it should use the "static file handler" (whatever that is)? Should I expect my Application_Error to be invoked?

• Setting current culture with threads in ASP.NET MVC

  - by mare

  Here's an example of SetCulture attribute which inside does something like this: public void OnActionExecuting(ActionExecutingContext filterContext) { string cultureCode = SetCurrentLanguage(filterContext); if (string.IsNullOrEmpty(cultureCode)) return; HttpContext.Current.Response.Cookies.Add( new HttpCookie("Culture", cultureCode) { HttpOnly = true, Expires = DateTime.Now.AddYears(100) } ); filterContext.HttpContext.Session["Culture"] = cultureCode; CultureInfo culture = new CultureInfo(cultureCode); System.Threading.Thread.CurrentThread.CurrentCulture = culture; System.Threading.Thread.CurrentThread.CurrentUICulture = culture; } I was wondering how does this affect a site with multiple users logged on and each one setting their own culture? What is the scope of a thread here with regards to the IIS worker process (w3wp) that the site is running in?

I would create the class car. Every car has his own color, position and so on. And I could create the road with an array. But how to tell the car where to go? Could I hear your ideas? EDIT: Is it forbidden to get new ideas from good programmers? Why do some people want to close this thread? Or were to ask such questions? I dont understand them. :(

• T SQL WHERE Clause

  - by johniom

  Hiya Guys, I'm trying to develop some code which pulls latest informtion only. What it is when a user goes into a form there a subtable and everytime they change something it creates a new row in the colum called type12_OriginalNoteID which puts its own unquie number in. Another feild called type12_OriginalNoteID keeps the same number - which keeps track of what the oringal number was before any changes were made. I do have some code which does pull the latest information but it does not pull anything if the user has not made any changes to the form - and thats because the type12_OriginalNoteID is null. The code is as follows ea.type12_NoteID IN (SELECT TOP 1 ea.type12_NoteID FROM UserAssessv1aidsadaptations ea1 WHERE ea.type12_NoteID = ea1.type12_OriginalNoteID ORDER BY ea.type12_UpdatedDate DESC) An example of the data is as follows :- type12_note ID - 12 type12_OriginalNoteID NULL type12_UpdatedDate - 11/03/2010 What would be the solution to show the ifnroamtion if no one has made any changes to the subtable? - adding an if statement to run if type12_OriginalNoteID is null??

• Forumotion profile customization using jQuery based on URL

  - by Harvengure

  The idea is have a jQuery snippet (I like Jquery...I can understand it better then regular javascript) that will detect that when it has been run on a profile with a url such as "http://customize.forum-motion.com/profile.forum?mode=viewprofile&u=1" (just as an example)...then upon detecting that it is a url of a profile...fetch data from a specific (and most likely hidden) element before wrapping that data in css tags and appending it to the heady of the current document. In short I'm trying to figure out how to make a sort of profile customization system where users can create their own css. The biggest problem I am having so far is figuring out how to make it so that the snippet can figure out what URL its being run on. Is there a function that can do this in jQuery at all?

• Home Pages in ASP.NET MVC

  - by Maxim Z.

  I'm trying out ASP.NET MVC, but, after reading a huge tutorial, I'm slightly confused. I understand how Controllers have Actions that URLs are routed to, but how do home pages work? Is the home page its own controller (e.g. "Home") that has no actions? This sounds correct, but how is it functionality implemented without Actions (no Actions means no methods that call the View Engine)? In other words, my question is this: how are home pages implemented (in terms of Controllers and Views)? Could you please provide sample code?
