  • Is it possible from Spring to inject the result of calling a method on a ref bean?

    - by Alex Worden
    Hi, Is it possible from Spring to inject the result of calling a method on a ref bean? I'm trying to refactor some cut/pasted code from two separate projects into a common class. In one of the projects, the code lives in a class I'll call "MyClient" that is being instantiated from Spring. It is injected with another spring-instantiated class "MyRegistry", then the MyClient class uses that class to look up an endpoint. All I really need is the endpoint String in my refactored class, which can be initialized via a Setter. I really cannot have a dependency on MyRegistry from MyClient in the refactored code. So, my question is this... is there a way I can inject the endpoint String from spring that was looked up in the MyRegistry class. So, I currently have: <bean id="registryService" class="foo.MyRegistry"> ...properties set etc... </bean> <bean id="MyClient" class="foo.MyClient"> <property name="registry" ref="registryService"/> </bean> But I'd like to have (and I know this is imaginary Spring syntax) <bean id="MyClient" class="foo.MyClient"> <property name="endPoint" value="registryService.getEndPoint('bar')"/> </bean> where MyRegistry will have a method getEndPoint(Stirng endPointName) Hope that makes sense from a the standpoint of what I'm trying to achieve. Please let me know if something like this is possible in Spring!

  • Need a SQL statement focus on combination of tables but entries always with uinque ID

    - by Registered User KC
    Hi All, I need SQL code to solve the tables combination problem, described on below: Table old data: name version status lastupdate ID A 0.1 on 6/8/2010 1 B 0.1 on 6/8/2010 2 C 0.1 on 6/8/2010 3 D 0.1 on 6/8/2010 4 E 0.1 on 6/8/2010 5 F 0.1 on 6/8/2010 6 G 0.1 on 6/8/2010 7 Table new data: name version status lastupdate ID A 0.1 on 6/18/2010 #B entry deleted C 0.3 on 6/18/2010 #version_updated C1 0.1 on 6/18/2010 D 0.1 on 6/18/2010 E 0.1 off 6/18/2010 #status_updated F 0.1 on 6/18/2010 G 0.1 on 6/18/2010 H 0.1 on 6/18/2010 #new_added H1 0.1 on 6/18/2010 #new_added the difference of new data and old date: B entry deleted C entry version updated E entry status updated C1/H/H1 entry new added What I want is always keeping the ID - name mapping relationship in old data table no matter how data changed later, a.k.a the name always has a unique ID number bind with it. If entry has update, then update the data, if entry is new added, insert to the table then give a new assigned unique ID. However, I can only use SQL with simple select or update statement then it may too hard for me to write such code, then I hope someone with expertise can give direction, no details needed on the different of SQL variant, a standard sql code as sample is enough. Thanks in advance! Rgs KC

  • How to convert source code to a xml based representation of the ast?

    - by autobiographer
    i wanna get a xml representation of the ast of java and c code. 3 months ago, i asked this question yet but the solutions weren't comfortable for me srcml seems to be a good solution for this problem but it does not support line numbers and columns but i need that feature. about elsa: cite: "There is ongoing effort to export the Elsa AST as an XML document; we expect to be able to advertise this in the next public release." dms... didn't understand that. especially for java, there is javaml which supports line numbers. but the sourceforge page doesn't list any files. question: there's software available which supports conversion of ast into xml which supports line numbers (and columns) [especially for java and c/c++]? is there an alternative to javaml and srcml? ps: i don't wanne have parser generators. i hope to find a tool which can be used on the console typing: ./my-xml-generator Test.java [or something like that]... or a java implementation would be great too.

  • How can I speed up Subversion checkins? (Using ANKH, latest, Visual Studio 2010)

    - by Timothy Khouri
    I've started working on a new web project with some friends... we are using the latest Subversion server (installed last week), the latest version of ANKH. My web project is a whapping 1.5 megabytes (that's with all images, css files, dll's after compiling, pdb files... etc). Checking in even super small changes (literally adding the letter "x" to a few files for testing)... takes FOREVER! (about 10 seconds - I almost killed myself). The ANKH client is measuring in BYTES PER SECOND ... BYTES? per second... I must be doing something wrong. Does anyone what config file has a joke totallyMessWithPeople=true so that I can turn that off or something? Oh, also, changing one "big" file of a super 10k gains speed up to nearly the speed of light (which is apparently 857 bytes per second). Help me obi wan kenobi, your my only hope! EDIT: As a note... my real work project that uses Visual Source Safe 2005 (I know, ouch) uploads files at about 200-500kbps from this very same computer/internet connection.

  • Stuck on Object scope in Java

    - by ivor
    Hello, I'm working my way through an exercise to understand Java, and basically I need to merge the functionality of two classes into one app. I'm stuck on one area though - the referencing of objects across classes. What I have done is set up a gui in one class (test1), and this has a textfield in ie. chatLine = new JTextField(); in another class(test2), I was planning on leaving all the functionality in there and referencing the various gui elements set up in test1 - like this test1.chatLine I understand this level of referencing, I tested this by setting up a test method in the test2 class public static void testpass() { test1.testfield.setText("hello"); } I'm trying to understand how to implement the more complex functionality in test2 class though, specifically this existing code; test1.chatLine.addActionListener(new ActionAdapter() { public void actionPerformed(ActionEvent e) { String s = Game.chatLine.getText(); if (!s.equals("")) { appendToChatBox("OUTGOING: " + s + "\n"); Game.chatLine.selectAll(); // Send the string sendString(s); } } }); This is the bit I'm stuck on, if I should be able to do this - as it's failing on the compile, can I add the actionadapter stuff to the gui element thats sat in test1, but do this from test2 - I'm wondering if I'm trying to do something that's not possible. Hope this makes sense, I'm pretty confused over this - I'm trying to understand how the scope and referencing works. Ideally what i'm trying to achieve is one class that has all the main stuff in, the gui etc, then all the related functionality in the other class, and target the first class's gui elements with the results etc. Any thoughts greatly appreciated.

  • Why did instruments report a leak while its ref count did become zero

    - by bromj
    Hello guys, green hand i am. I'm using instruments, and it did a great help to me so far, but I'm confused now 'cause it report a memory leak to me while its leaked block history shows me that the ref count of that memory had finally become 0. What does it mean? It's really embarrassing that I couldn't post a image here... so I have to describe it in text. Hope it would be clear enough for you: Event Type || RefCt || Responsible Library || Responsible Caller Malloc         || 1        || MyWeather              || +[ForecastData parseSingleForecastWithXMLElement:] Autorelease||           || MyWeather              || +[ForecastData parseSingleForecastWithXMLElement:] Retain         || 2        || MyWeather              || +[ForecastData parseWithData:] Release      || 1        || Foundation              || +[NSAutoreleasePool drain:] Retain         || 2        || Foundation              || +[NSThread initWithTarget:selector:object:] Release      || 1        || Foundation              || +[NSString compare:options:] Release      || 0        || MyWeather              || +[RootViewController dealloc] Any help will be appreciated~

  • Best and simple way to handle JSON in Django

    - by primal
    Hi, As part of the application we are developing (with android client and Django server) a json object which contains user name and pass word is sent to server from android client as follows HttpPost post = new HttpPost(URL); /*Adding key value pairs */ json.put("username", un); json.put("password", pwd); StringEntity se = new StringEntity(json.toString()); post.setEntity(se); response = client.execute(post); The response is parsed like this result = responsetoString(response.getEntity().getContent()); //Converts response to String jObject = new JSONObject(result); JSONObject post = jObject.getJSONObject("post"); username = post.getString("username"); message = post.getString("message"); Hope upto this everything is fine. The problem comes when parsing or sending JSON responses in Django server. Whats the best way to do this? We tried using SimpleJSON and it turned out not to be so simple as we didn't find any good tutorials or sample code for the same? Are there any python functions similiar to get,put and opt in java for JSON? Any help would be much appreciated..

  • How to specify a parameter as part of every web service call?

    - by LES2
    Currently, each web service for our application has a user parameter that is added for every method. For example: @WebService public interface FooWebService { @WebMethod public Foo getFoo(@WebParam(name="alwaysHere",header=true,partName="alwaysHere") String user, @WebParam(name="fooId") Long fooId); @WebMethod public Result deletetFoo(@WebParam(name="alwaysHere",header=true,partName="alwaysHere") String user, @WebParam(name="fooId") Long fooId); // ... } There could be twenty methods in a service, each with the first parameter as user. And there could be twenty web services. We don't actually use the 'user' argument in the implementations - in fact, I don't know why it's there - but I wasn't involved in the design, and the person that put it there had a reason (I hope). Anyway, I'm trying to straighten out this Big Ball of Mud. I have already come a long way by wrapping the web services by a Spring proxy, which allows me to do some before-and-after processing in an interceptor (before there were at least 20 lines of copy-pasted boiler plate per method). I'm wondering if there's some kind of "message header" I can apply to the method or package and that can be accessed by some type of handler or something outside of each web service method. Thanks in advance for the advice, LES

  • PHP programmer wanting to learn Flash game development

    - by grokker
    Hi! I'm currently a PHP programmer and one of my childhood dreams is to create a game. A game to show my friends or my children when the time comes :) The problem is I don't know Flash. I'm not great at drawing stuff or even artistic. I could program a little with Javascript and I could consider myself intermediate with jQuery. So my question is, how do I get started? What books do I read first? What's the steps that I should take on this journey? Thank you SO friends. I hope you all could help me create something I could be proud of :) P.S. I'm just assuming that Flash is the easiest way to create and show to other people my game. Anyway I'm very open for other suggestions! My game in mind is a side scroller about an indiana jones type of character and the setting is on the jungle with trees and snakes and a lot of animals!

  • if/else statement in a function: using onclick as a switch

    - by Aurora Schmidt
    I have looked for solutions to this on google for what seems like an eternity, but I can't seem to formulate my search correctly, or nobody has posted the code I'm looking for earlier. I am currently trying to make a function that will modify one or several margins of a div element. I want to use an if/else statement within the function, so that the onclick event will switch between the two conditions. This is what I have been working on so far; function facebookToggle() { if($('#facebooktab').style.margin-left == "-250px";) { document.getElementById("facebooktab").style.marginLeft="0px"; } else { document.getElementById("facebooktab").style.marginLeft="-250px"; } } I have tried twisting it around a little, like switching between "marginLeft" and "margin-left", to see if I was just using the wrong terms.. I'm starting to wonder if it might not be possible to combine jQuery and regular javascript? I don't know.. It's all just guesses on my part at this point. Anyway, I have a div, which is now positioned (fixed) so almost all of it is hidden outside the borders of the browser. I want the margin to change onclick so that it will be fully shown on the page. And when it is shown, I want to be able to hide it again by clicking it. I might be approaching this in the wrong way, but I really hope someone can help me out, or even tell me another way to get the same results. Thank you for any help you can give me. You can see it in action at: http://www.torucon.no/test/ (EDIT: By the way, I am a complete javascript novice, I have no experience with javascript prior to this experiment. Please don't be too harsh, as I am aware I probably made some really stupid mistakes in this short code.) EDITED CODE: function facebookToggle() { if($('#facebooktab').css('margin-left', '-250px') { $('#facebooktab').css('margin-left', '0px'); } else { $('#facebooktab').css('margin-left', '-250px'); } }

  • Using JavaCC to infer semantics from a Composite tree

    - by Skice
    Hi all, I am programming (in Java) a very limited symbolic calculus library that manages polynomials, exponentials and expolinomials (sums of elements like "x^n * e^(c x)"). I want the library to be extensible in the sense of new analytic forms (trigonometric, etc.) or new kinds of operations (logarithm, domain transformations, etc.), so a Composite pattern that represent the syntactic structure of an expression, together with a bunch of Visitors for the operations, does the job quite well. My problem arise when I try to implement operations that depends on the semantics more than on the syntax of the Expression (like integrals, for instance: there are a lot of resolution methods for specific classes of functions, but these same classes can be represented with more than a single syntax). So I thought I need something to "parse" the Composite tree to infer its semantics in order to invoke the right integration method (if any). Someone pointed me to JavaCC, but all the examples I've seen deal only with string parsing; so, I don't know if I'm digging in the right direction. Some suggestions? (I hope to have been clear enough!)

  • UML Modelling in C++Builder 2010 Professional

    - by Gordon Brandly
    I'd like to do some basic class diagram UML models in the Pro version of C++Builder 2010. Embarcadero has a C++Builder Features Matrix document, one line of which says "UML Code Visualization – at any time, get a UML model view of your source code" and has a check in the "Professional" column of that table -- I assume this means it should be available to me. Yet, when I open an existing project and do a View | Model View, there's nothing in the Model View window. The only diagram I can find is on the Graph tab of the C++ Class Explorer. I wouldn't call that a UML diagram myself -- is that what Embarcadero is referring to? Embarcadero's table shows that many UML diagrams are not available in Pro, but it looks to me like Class Diagrams should be available. Other lines in that same table indicate that both "Full two-way class diagrams with synchronization between code and diagrams" and "Diagram hyper-linking and annotations" are also supposed to be available in Pro. The Class Explorer graph is one-way only as far as I can tell, so I hope they're referring to something else I haven't been able to find so far. Thanks for any insight into this.

  • Why does gcc generate verbose assembly code?

    - by Jared Nash
    I have a question about assembly code generated by GCC (-S option). Since, I am new to assembly language and know very little about it, the question will be very primitive. Still, I hope somebody will answer: Suppose, I have this C code: main(){ int x = 15; int y = 6; int z = x - y; return 0; } If we look at the assembly code (especially the part corresponding to int z = x - y ), we see: main: ... subl $16, %esp movl $15, -4(%ebp) movl $6, -8(%ebp) movl -8(%ebp), %eax movl -4(%ebp), %edx movl %edx, %ecx subl %eax, %ecx movl %ecx, %eax movl %eax, -12(%ebp) ... Why doesn't GCC generate something like this, which is less copying things around. main: ... movl $15, -4(%ebp) movl $6, -8(%ebp) movl -8(%ebp), %edx movl -4(%ebp), %eax subl %edx, %eax movl %eax, -12(%ebp) ... P.S. Linux zion-5 2.6.32-21-generic #32-Ubuntu SMP Fri Apr 16 08:10:02 UTC 2010 i686 GNU/Linux gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5)

  • Project euler problem 45

    - by Peter
    Hi, I'm not yet a skilled programmer but I thought this was an interesting problem and I thought I'd give it a go. Triangle, pentagonal, and hexagonal numbers are generated by the following formulae: Triangle T_(n)=n(n+1)/2 1, 3, 6, 10, 15, ... Pentagonal P_(n)=n(3n-1)/2 1, 5, 12, 22, 35, ... Hexagonal H_(n)=n(2n-1) 1, 6, 15, 28, 45, ... It can be verified that T_(285) = P_(165) = H_(143) = 40755. Find the next triangle number that is also pentagonal and hexagonal. Is the task description. I know that Hexagonal numbers are a subset of triangle numbers which means that you only have to find a number where Hn=Pn. But I can't seem to get my code to work. I only know java language which is why I'm having trouble finding a solution on the net womewhere. Anyway hope someone can help. Here's my code public class NextNumber { public NextNumber() { next(); } public void next() { int n = 144; int i = 165; int p = i * (3 * i - 1) / 2; int h = n * (2 * n - 1); while(p!=h) { n++; h = n * (2 * n - 1); if (h == p) { System.out.println("the next triangular number is" + h); } else { while (h > p) { i++; p = i * (3 * i - 1) / 2; } if (h == p) { System.out.println("the next triangular number is" + h); break; } else if (p > h) { System.out.println("bummer"); } } } } } I realize it's probably a very slow and ineffecient code but that doesn't concern me much at this point I only care about finding the next number even if it would take my computer years :) .

  • Scriptaculous problem in IE

    - by Django Reinhardt
    Hi there. We've got this very annoying problem with Scriptaculous and Internet Explorer 7/8. We have two Effect.toggles on the same page, but only one of them is ever working (the first one). I hope it's some simple mistake in my implementation, but I can't seem to find any decent documentation. Hopefully somebody here can help. The HTML/JS looks like this: <ul> <li id="LinkA" class="icon"> <a onclick="new Effect.toggle('divA', 'slide', { duration: 0.6 }); return false;" href="#">Show List A</a> </li> </ul> <div id="divA" style="display:none"> <div> -- Things to display -- </div> </div> <ul> <li id="LinkB" class="icon"> <a onclick="new Effect.toggle('divB', 'slide', { duration: 0.6 }); return false;" href="#">Show List B</a> </li> </ul> <div id="divB" style="display:none"> <div> -- Things to display -- </div> </div> It works perfectly in Chrome and Firefox, but the second one never works in IE 7 or 8, no matter what I do. Any help would be greatly appreciated!

  • Exec problem in SQL Server 2005

    - by IordanTanev
    Hi, I have the situation where i have two databases with same structure. The first have some data in its data tables. I need to create a script that will transfer the data from the first database to the second. I have created this script. DECLARE @table_name nvarchar(MAX), @query nvarchar(MAX) DECLARE @table_cursor CURSOR SET @table_cursor = CURSOR FAST_FORWARD FOR SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES OPEN @table_cursor FETCH NEXT FROM @table_cursor INTO @table_name WHILE @@FETCH_STATUS = 0 BEGIN SET @query = 'INSERT INTO ' + @table_name + ' SELECT * FROM MyDataBase.dbo.' + @table_name print @query exec @query FETCH NEXT FROM @table_cursor INTO @table_name END CLOSE @table_cursor DEALLOCATE @table_cursor The problem is that when I run the script the "print @query" statement prints statement like this INSERT INTO table SELECT * FROM MyDataBase.dbo.table When I copy this and run it from Management studio it works fine. But when the script tries to run it with exec I get this error Msg 911, Level 16, State 1, Line 21 Could not locate entry in sysdatabases for database 'INSERT INTO table SELECT * FROM MPDEV090314'. No entry found with that name. Make sure that the name is entered correctly. Hope someone can tell me whot is wront with this. Best Regards, Iordan Tanev

  • How Can I Create Reports in a Custom C#.NET Windows Application? - General Question

    - by user311509
    Assume i have a custom Windows application written in C#. This application has only the following functionalists, add, edit, delete and view. For example, a user can add a sale, change sales record, delete a sale record or view the whole sales record. I need to add some reporting functionalists e.g. i want a user to print the sales of a certain customer from 2008 to 2009 into pdf, what all products a certain customer has purchased from us and so on. I will only include the basic common report requests that are usually needed in the office. Any other kind of reports that are requested inconsistently, i would do it manually from my side at the back end and send the results manually to the requester. What i would do is: If a user wants more info of a certain customer, a special window box appears for that customer. This window box will have different controls that allows user to request more info such as, print customer purchases from ..... to ..... (user chooses the dates) and user will view results in pdf or so. Of course, at the back scene i will write an appropriate SQL Query with parameters that meets a certain function. Is this how it should be done? I have heard about SQL Reporting, i don't know anything about it yet. I will check it out. Anyhow, your suggestions won't harm. I'm still a student, so i don't have practical experience yet. I hope my question is clear enough. Thank you.

  • Case Insensitive Ternary Search Tree

    - by Yan Cheng CHEOK
    I had been using Ternary Search Tree for a while, as the data structure to implement a auto complete drop down combo box. Which means, when user type "fo", the drop down combo box will display foo food football The problem is, my current used of Ternary Search Tree is case sensitive. My implementation is as follow. It had been used by real world for around 1++ yeas. Hence, I consider it as quite reliable. My Ternary Search Tree code However, I am looking for a case insensitive Ternary Search Tree, which means, when I type "fo", the drop down combo box will show me foO Food fooTBall Here are some key interface for TST, where I hope the new case insentive TST may have similar interface too. /** * Stores value in the TernarySearchTree. The value may be retrieved using key. * @param key A string that indexes the object to be stored. * @param value The object to be stored in the tree. */ public void put(String key, E value) { getOrCreateNode(key).data = value; } /** * Retrieve the object indexed by key. * @param key A String index. * @return Object The object retrieved from the TernarySearchTree. */ public E get(String key) { TSTNode<E> node = getNode(key); if(node==null) return null; return node.data; } An example of usage is as follow. TSTSearchEngine is using TernarySearchTree as the core backbone. Example usage of Ternary Search Tree // There is stock named microsoft and MICROChip inside stocks ArrayList.

  • Search and replace with sed

    - by Binoy Babu
    Last week I accidently externalized all my strings of my eclipse project. I need to revert this and my only hope is sed. I tried to create scripts but failed pathetically because I'm new with sed and this would be a very complicated operation. What I need to do is this: Strings in class.java file is currently in the following format(method) Messages.getString(<key>). Example : if (new File(DataSource.DEFAULT_VS_PATH).exists()) { for (int i = 1; i <= c; i++) { if (!new File(DataSource.DEFAULT_VS_PATH + Messages.getString("VSDataSource.89") + i).exists()) { //$NON-NLS-1$ getnewvfspath = DataSource.DEFAULT_VS_PATH + Messages.getString("VSDataSource.90") + i; //$NON-NLS-1$ break; } } } The key and matching Strings are in messages.properties file in the following format. VSDataSource.92=No of rows in db = VSDataSource.93=Verifying db entry : VSDataSource.94=DB is open VSDataSource.95=DB is closed VSDataSource.96=Invalid db entry for VSDataSource.97=\ removed. So I need the java file back in this format: if (new File(DataSource.DEFAULT_VS_PATH).exists()) { for (int i = 1; i <= c; i++) { if (!new File(DataSource.DEFAULT_VS_PATH + "String 2" + i).exists()) { //$NON-NLS-1$ getnewvfspath = DataSource.DEFAULT_VS_PATH + "String 1" + i; //$NON-NLS-1$ break; } } } How can I accomplish this with sed? Or is there an easier way?

  • how to make an import library

    - by user295030
    a requirement was sent to me below: API should be in the form of static library. company xxx will link the library into a third party application to prevent any possible exposure of the code(dll) could they mean an import library? An import library is a library that automates the process of loading and using a dynamic library. On Windows, this is typically done via a small static library (.lib) of the same name as the dynamic library (.dll). The static library is linked into the program at compile time, and then the functionality of the dynamic library can effectively be used as if it were a static library. this might be what they might be eluding to.....I am not sure how to make this in vs2008 . Additional facts: I have a static lib that i use in my current application. Now, I have to convert my app that uses that static lib into an import lib so that they can use a third party prog to access the API's they providede me which in turn will use that static lib i am using. I hope I am clearly explaining this. I am just not sure how to go about it in vs2008. I am looking for specific steps to do this. I already have the coding done. Just need to convert it into the form they are asking and I have to provide the API they want. Other than that then I need to create a test prog which will act as that third party prog so I can make sure my import library works.

  • Pass an Event as parameter

    - by dkson
    I have a class which bundles events and registers controls to easily register/unregister them, it's basically used this way: Private Sub MyFocusHandler(ByVal sender As Object, ...) ... End Sub ... Dim b1 = new MyTextBox() Dim b2 = new MyTextBox() .... 'Lot of Controls' Dim cr = new ControlRegistration() cr.RegisterControl(b1) cr.RegisterControl(b2) .... 'Register a lot of controls' cr.RegisterEvent("Focus",New EventHandler(AddressOf MyFocusHandler)) cr.RegisterEvent("Validate",New EventHandler(AddressOf MyValidateHandler)) So I don't have to add the handlers manually for each control. The ControlRegistration-Class will cycle through the list of registered controls and check if a control has a registered event and then attach the eventhandler, something like: ... For Each control in contols Dim ev_info As Reflection.EventInfo = _ control.GetType().GetEvent(.GetType().GetEvent(event_name)) If Not (ev_info Is Nothing) Then ev_info.AddEventHandler ... ... My problem is that i am identifying the event by a string Public Sub RegisterEvent(ByVal eventName As String, ByVal handler As [Delegate]) ... ... cr.RegisterEvent("Focus",New EventHandler(AddressOf MyFocusHandler)) I don't want to depend on the name of the event, since it is possibly that the name changes, and then things will break up. Is there a way I can do this like: Public Sub RegisterEvent(ByVal theEvent As ???, ByVal handler As [Delegate]) ... ... cr.RegisterEvent(IMyControl.MyEvent,New EventHandler(AddressOf MyEventHandler)) I hope it is clear what I want to archive. Anybody any ideas? Thanks

  • Who architected / designed C++'s IOStreams, and would it still be considered well-designed by today'

    - by stakx
    First off, it may seem that I'm asking for subjective opinions, but that's not what I'm after. I'd love to hear some well-grounded arguments on this topic. In the hope of getting some insight into how a modern streams / serialization framework ought to be designed, I recently got myself a copy of the book Standard C++ IOStreams and Locales by Angelika Langer and Klaus Kreft. I figured that if IOStreams wasn't well-designed, it wouldn't have made it into the C++ standard library in the first place. After having read various parts of this book, I am starting to have doubts if IOStreams can compare to e.g. the STL from an overall architectural point-of-view. Read e.g. this interview with Alexander Stepanov (the STL's "inventor") to learn about some design decisions that went into the STL. What surprises me in particular: It seems to be unknown who was responsible for IOStreams' overall design (I'd love to read some background information about this — does anyone know good resources?); Once you delve beneath the immediate surface of IOStreams, e.g. if you want to extend IOStreams with your own classes, you get to an interface with fairly cryptic and confusing member function names, e.g. getloc/imbue, uflow/underflow, snextc/sbumpc/sgetc/sgetn, pbase/pptr/epptr (and there's probably even worse examples). This makes it so much harder to understand the overall design and how the single parts co-operate. Even the book I mentioned above doesn't help that much (IMHO). Thus my question: If you had to judge by today's software engineering standards (if there actually is any general agreement on these), would C++'s IOStreams still be considered well-designed? (I wouldn't want to improve my software design skills from something that's generally considered outdated.)

  • Making a sqlite file stay existent between runs of the program

    - by Cocorico
    Hi! I'm having a problem with some sqlite code for an iPhone program in Xcode. I was opening my database like this: int result = sqlite3_open("stealtown.db", &database); Which is how they had it in a book I was looking at while I type the program. But then, that way of opening a database it only works when you run in simulator, not on device. So I finally figure out I need to do this: NSString *file = [[NSBundle mainBundle] pathForResource:@"stealtown" ofType:@"db"]; int result = sqlite3_open([file UTF8String], &database); And that works on device, EXCEPT one thing: Each time you launch the program, it starts as if you had never created the database, and when you stick an entry in the table, it's the ONLY entry in that table. When I used the first code on the simulator, I could open my program 6 times, each time adding 1 entry to a table, and at the end, I had 6 entries in that table. With the second code, I do exact same thing but each time there is only 1 entry in that table. Am I explaining this okay, I hope so, it's hard sometimes for me. Anyone maybe know why this would be?

  • User preferences using SQL and JavaScript

    - by Shyam
    Hi, I am using Server Side JavaScript - yes, I am actually using Server Side JavaScript. To complexify things even more, I use Oracle as a backend database (10g). With some crazy XSLT and mutant-like HTML generation, I can build really fancy web forms - yes, I am aware of Rails and other likewise frameworks and I choose the path of horror instead. I have no JQuery or other fancy framework at my disposal, just plain ol' JavaScript that should be supported by the underlying engine called Mozilla Rhino. Yes, it is insane and I love it. So, I have a bunch of tables at my disposal and some of them are filled with associative keys that link to values. As I am a people pleaser, I want to add some nifty user-preference driven solutions. My users have all an unique user_id and this user_id is available during the entire session. My initial idea is to have a user preference table, where I have "three" columns: user_id, feature and pref_string. Using a delimiter, such as : or - (haven't thought about a suitable one yet), I could like store a bunch of preferences as a list and store its elements inside an array using the .split-method (similar like the PHP-explode function). The feature column could be like the table name or some identifier for the "feature" i want to link preferences too. I hate hardcoding objects, especially as I want to be able to back these up and reuse this functionality application-wide. Of course I would love better ideas, just keep in mind I cannot just add a library that easily. These preferences could be like "joined" to the table, so I can query it and use its values. I hope it doesn't sounds too complex, because well.. its basically something really simple I need. Thanks!
