  • Delphi Mock Wizard

    - by Todd
    Let me preface this by saying I'm fairly new to Unit Testing, Mocks, Stubs, Etc... I've installed Delphi-Mock-Wizard. When I select a unit and "Generate Mock", a new unit is created but it's very basic and not anything what I understand Mocks to be. unit Unit1; (** WARNING - AUTO-GENERATED MOCK! Change this unit if you want to, but be aware that any changes you make will be lost if you regenerate the mock object (for instance, if the interface changes). My advice is to create a descendent class of your auto-generated mock - in a different unit - and override things there. That way you get to keep them. Also, the auto-generate code is not yet smart enough to generate stubs for inherited interfaces. In that case, change your mock declaration to inherit from a mock implementation that implements the missing interface. This, unfortunately, is a violation of the directive above. I'm working on it. You may also need to manually change the unit name, above. Another thing I am working on. **) interface uses PascalMock, TestInterfaces; type IThingy = interface; implementation end. Looking at the source there seems to be quite a bit commented out. I'm wondering, has anyone gotten this to work? My IDE is D2010. Thanks.

  • What objects would get defined in a Bridge scoring app (Javascript)

    - by Alex Mcp
    I'm writing a Bridge (card game) scoring application as practice in javascript, and am looking for suggestions on how to set up my objects. I'm pretty new to OO in general, and would love a survey of how and why people would structure a program to do this (the "survey" begets the CW mark. Additionally, I'll happily close this if it's out of range of typical SO discussion). The platform is going to be a web-app for webkit on the iPhone, so local storage is an option. My basic structure is like this: var Team = { player1: , player2: , vulnerable: , //this is a flag for whether or //not you've lost a game yet, affects scoring scoreAboveLine: , scoreBelowLine: gamesWon: }; var Game = { init: ,//function to get old scores and teams from DB currentBid: , score: , //function to accept whether bid was made and apply to Teams{} save: //auto-run that is called after each game to commit to DB }; So basically I'll instantiate two teams, and then run loops of game.currentBid() and game.score. Functionally the scoring is working fine, but I'm wondering if this is how someone else would choose to break down the scoring of Bridge, and if there are any oversights I've made with regards to OO-ness and how I've abstracted the game. Thanks!

  • How to arrange business logic in a Kohana 3 project

    - by Pekka
    I'm looking for advice, tutorials and links at how to set up a mid-sized web application with Kohana 3. I have implemented MVC patterns in the past but never worked against a "formalized" MVC framework so I'm still getting my head around the terminology - toying around with basic examples, building views and templates, and so on. I'm progressing fairly well but I want to set up a real-world web project (one of my own that I've been planning for quite some time now) as a learning object. I learn best by example, but example-based documentation is a bit sparse for Kohana 3 right now - they say so themselves on the site. While I'm not worried about learning the framework as I go along, I want to make sure the code base is healthily structured from the start - i.e. controllers are split nicely, named well and according to standards, and most importantly the business logic is separated into appropriately sized models. My application could, in its core, be described as a business directory with a range of search and listing functions, and a login area for each entry owner. The actual administrative database backend is already taken care of. Supposing I have all the API worked out and in place already - list all businesses, edit business, list businesses by street name, create offer logged in as business, and so on, and I'm just looking for how to fit the functionality into a MVC pattern and into a Kohana application structure that can be easily extended. Do you know real-life examples of "database-heavy" applications like directories, online communities... with a log-in area built on Kohana 3, preferably Open Source so I could take a peek how they do it? Are there conventions or best practices on how to structure an extendable login area for end users in a Kohana project that is not only able to handle a business directory page, but further products on separate pages as well? Do you know any good resources on building complex applications with Kohana? Have you built something similar and could give me recommendations on a project structure?

  • Floating point precision in Visual C++

    - by Luigi Giaccari
    HI, I am trying to use the robust predicates for computational geometry from Jonathan Richard Shewchuk. I am not a programmer, so I am not even sure of what I am saying, I may be doing some basic mistake. The point is the predicates should allow for precise aritmthetic with adaptive floating point precision. On my computer: Asus pro31/S (Core Due Centrino Processor) they do not work. The problem may stay in the fact the my computer may use some improvements in the floating point precision taht conflicts with the one used by Shewchuk. The author says: /* On some machines, the exact arithmetic routines might be defeated by the / / use of internal extended precision floating-point registers. Sometimes / / this problem can be fixed by defining certain values to be volatile, / / thus forcing them to be stored to memory and rounded off. This isn't / / a great solution, though, as it slows the arithmetic down. */ Now what I would like to know is that there is a way, maybe some compiler option, to turn off the internal extended precision floating-point registers. I really appriaciate your help

  • ASP.NET Event delegation between user controls

    - by Ishan
    Give the following control hierarchy on a ASP.NET page: Page HeaderControl       (User Control) TitleControl       (Server Control) TabsControl       (User Control) other controls I'm trying to raise an event (or some notification) in the TitleControl that bubbles to the Page level. Then, I'd like to (optionally) register an event handler at the Page codebehind that will take the EventArgs and modify the TabsControl in the example above. The important thing to note is that this design will allow me to drop these controls into any Page and make the entire system work seamlessly if the event handler is wired up. The solution should not involve a call to FindControl() since that becomes a strong association. If no handler is defined in the containing Page, the event is still raised by TitleControl but is not handled. My basic goal is to use event-based programming so that I can decouple the user controls from each other. The event from TitleControl is only raised in some instances, and this seemed to be (in my head) the preferred approach. However, I can't seem to find a way to cleanly achieve this. Here are my (poor) attempts: Using HttpContext.Current.Items Add the EventArgs to the Items collection on TitleControl and pick it up on the TabsControl. This works but it's fundamentally hard to decipher since the connection between the two controls is not obvious. Using Reflection Instead of passing events, look for a function on the container Page directly within TitleControl as in: Page.GetType().GetMethod("TabControlHandler").Invoke(Page, EventArgs); This will work, but the method name will have to be a constant that all Page instances will have to defined verbatim. I'm sure that I'm over-thinking this and there must be a prettier solution using delegation, but I can't seem to think of it. Any thoughts?

  • Form values in a list item

    - by Tri
    Here is the site mock-up I'm working on for my job: http://dev.arm.gov/~noensie/dqhands/cgi-bin/explorer. I'm still a novice in web developing and I need help with placing form values in a list item to pass on to another page. I'd rather not go in great detail the purpose of this website, but in terms of its basic use, select the parameters in the middle column for a request and add it to the list on the right column by pressing on "add request" button when it appears. After the list have been populated, a user would submit the selected requests, which will direct them to another page based on the requests selected (or added to the list, same thing). That last sentence is where I'm having a problem. Right now, each of request in the list in the right column are <li> elements and I assign them attribute values that needed to be passed on to the next page. I tried inserting a hidden input with same values, but I'm still not sure how to utilize that; I'm not even sure using the hidden input is the correct way. Also the "submit request" button is located outside the <form> block. I was going to utilize javascript and jQuery to enable the button to serialize the values in the <form> block, but I don't know quite how to do that. Go ahead and take a look at my javascript code (index.js) and slay me, or, I mean, my code. It's still pretty elementary and short (~260 lines, that's short right?). I will take any help for this problem (as the matter of fact, if you see any other problems or a better way of implementation of something, go ahead and mention that too); tips, advice, code samples, or whatever else you can contribute, it will be greatly appreciated.

  • Dependency Injection and decoupling of software layers

    - by cs31415
    I am trying to implement Dependency Injection to make my app tester friendly. I have a rather basic doubt. Data layer uses SqlConnection object to connect to a SQL server database. SqlConnection object is a dependency for data access layer. In accordance with the laws of dependency injection, we must not new() dependent objects, but rather accept them through constructor arguments. Not wanting to upset the DI gods, I dutifully create a constructor in my DAL that takes in SqlConnection. Business layer calls DAL. Business layer must therefore, pass in SqlConnection. Presentation layer calls Business layer. Hence it too, must pass in SqlConnection to business layer. This is great for class isolation and testability. But didn't we just couple the UI and Business layers to a specific implementation of the data layer which happens to use a relational database? Why do the Presentation and Business layers need to know that the underlying data store is SQL? What if the app needs to support multiple data sources other than SQL server (such as XML files, Comma delimited files etc.) Furthermore, what if I add another object upon which my data layer is dependent on (say, a second database). Now, I have to modify the upper layers to pass in this new object. How can I avoid this merry-go-round and reap all the benefits of DI without the pain?

  • [C#] How can we differentiate between SDK class objects and custom class objects?

    - by Nayan
    To give an idea of my requirement, consider these classes - class A { } class B { string m_sName; public string Name { get { return m_sName; } set { m_sName = value; } } int m_iVal; public int Val { get { return m_iVal; } set { m_iVal = value; } } A m_objA; public A AObject { get { return m_objA; } set { m_objA = value; } } } Now, I need to identify the classes of the objects passed to a function void MyFunc(object obj) { Type type = obj.GetType(); foreach (PropertyInfo pi in type.GetProperties()) { if (pi.PropertyType.IsClass) { //I need objects only if (!type.IsGenericType && type.FullName.ToLower() == "system.string") { object _obj = pi.GetValue(obj, null); //do something } } } } I don't like this piece of code - if (!type.IsGenericType && type.FullName.ToLower() == "system.string") { because then i have to filter out classes like, System.Int16, System.Int32, System.Boolean and so on. Is there an elegant way through which I can find out if the object is of a class defined by me and not of system provided basic classes?

  • Will IntelliTrace(tm) (historical debugging) be available for unmanaged c++ in future versions of Vi

    - by Tim
    I love the idea of historical debugging in VS 2010. However, I am really disappointed that unmanaged C++ is left out. IntelliTrace supports debugging Visual Basic and C# applications that use .NET version 2.0, 3.0, 3.5, or 4. You can debug most applications, including applications that were created by using ASP.NET, Windows Forms, WPF, Windows Workflow, and WCF. IntelliTrace does not support debugging C++, script, or other languages. Debugging of F# applications is supported on an experimental basis. (editorial) [This is really poor support in my opinion. .NET is less in need of this assistance than unmanaged c++. I an getting a little tired of the status of plain old C++ and its second-class status in the MS tools world. Yes, I realize it is probably WAAY easier to implement this with .NET and MS are pushing .NET as the future, and yes, I know that C++ is an "old" language, but that does not diminish the fact that there are lots of C++ apps out there and there will continue to be more apps built with C++. I sincerely hope MS has not dropped C++ as a supported developer tool/language- that would be a shame.] Does anyone know if there are plans for it to support C++?

  • SubViewTwoController undeclared (first use in this function) (obj-c)

    - by benny
    Ahoy hoy everyone :) Here is a list of links. You will need it when reading the post. I am a newbie to Objective-C and try to learn it for iPhone-App-Development. I used the tutorial linked in the link list to create a standard app with a simple basic Navigation. This app contains a "RootView" that is displayed at startup. The startup screen itself contains three elements wich all link to SubViewOne. I have got it to work this far. So what i want to change is to make the second element link to SubViewTwo. When i "Build and Go" it, i get the following errors: RootViewController.m: SubViewTwoController *subViewTwoController = [[SubViewTwoController alloc] init]; // SubViewTwoController undeclared (first use in this function) and in SubViewTwoController.m [super didReceiveMemoryWarning]; // Releases the view if it doesn't have a superview no superclass declared in @interface for ´SubViewTwoController´ and the same thing after - (void)dealloc { [super dealloc]; I think you will also need the header files, so here they are! RootViewController.h #import <UIKit/UIKit.h> @interface RootViewController : UITableViewController { IBOutlet NSMutableArray *views; } @property (nonatomic, retain) IBOutlet NSMutableArray *views; @end SubViewOneController.h #import <UIKit/UIKit.h> @interface SubViewOneController : UIViewController { IBOutlet UILabel *label; IBOutlet UIButton *button; } @property (retain,nonatomic) IBOutlet UILabel *label; @property (retain,nonatomic) IBOutlet UIButton *button; - (IBAction) OnButtonClick:(id) sender; @end and SubViewTwoController.h #import <UIKit/UIKit.h> @interface SubViewTwo : UIViewController { IBOutlet NSMutableArray *views; } @end I would be really great if you would leave your ideas with a short explanation. Thanks a lot in advance! benny

  • Is ASP.NET MVC is really MVC? Or how to separate model from controller?

    - by Andrey
    Hi all, This question is a bit rhetorical. At some point i got a feeling that ASP.NET MVC is not that authentic implementation of MVC pattern. Or i didn't understood it. Consider following domain: electric bulb, switch and motion detector. They are connected together and when you enter the room motion detector switches on the bulb. If i want to represent them as MVC: switch is model, because it holds the state and contains logic bulb is view, because it presents the state of model to human motion detector is controller, because it converts user actions to generic model commands Switch has one private field (On/Off) as a State and two methods (PressOn, PressOff). If you call PressOn when it is Off it goes to On, if you call it again state doesn't change. Bulb can be replaced with buzzer, motion detector with timer or button, but the model still represent the same logic. Eventually system will have same behavior. This is how i understand classical MVC decomposition, please correct me if i am wrong. Now let's decompose it in ASP.Net MVC way. Bulb is still a view Controller will be switch + motion detector Model is some object that will just pass state to bulb. So the logic that defines behavior moves to controller. Question 1: Is my understanding of MVC and ASP.NET MVC correct? Question 2: If yes, do you agree that ASP.NET MVC is not 100% accurate implementation? And back to life. The final question is how to separate model from controller in case of ASP.NET MVC. There can be two extremes. Controller does basic stuff and call model to do all the logic. Another is controller does all the logic and model is just something like class with properties that is mapped to DB. Question 3: Where should i draw the line between this extremes? How to balance? Thanks, Andrey

  • Restrict access to connection pool in Weblogic?

    - by Andrew White
    In short, how can I restrict access to connection pool X based on application name or JAR name? A simple use case might help... A business web-app (call it WEB_APP_A) uses pool Y to do basic look-up SQL. Some users of this web-app have access to also update some sensitive data in the database. This code is provided by a JAR file (call it HR_JAR) that can be dropped in where needed. This JAR uses pool X for all of it's connections. We don't want developers of WEB_APP_A using pool X. We only want HR_JAR using pool X. This is to keep devs of WEB_APP_A from accidentally or intentionally abusing the access pool X provides. Some considerations: This is legacy code so HR_JAR is here to stay We are running on Weblogic 9.2 We can not keep passwords in any from in the source code We have researched weblogic user level authn/authz for JDBC resources but then this begs the question; how do we secure the user creds we use to become a user per app/jar? Ideas? Thoughts? I can elaborate more on what I have tried, but I wanted fresh ideas.

  • How do I print an HTML document from a web service?

    - by Chris Marasti-Georg
    I want to print HTML from a C# web service. The Web Browser control is overkill, and does not function well in a service-environment, nor does it function well on a system with very tight security constraints. Is there any sort of free .NET library that will support the printing of a basic HTML page? Here is the code I have so far, that is not running properly. public void PrintThing(string document) { if (Thread.CurrentThread.GetApartmentState() != ApartmentState.STA) { Thread thread = new Thread((ThreadStart) delegate { PrintDocument(document); }); thread.SetApartmentState(ApartmentState.STA); thread.Start(); } else { PrintDocument(document); } } protected void PrintDocument(string document) { WebBrowser browser = new WebBrowser(); browser.DocumentText = document; while (browser.ReadyState != WebBrowserReadyState.Complete) { Application.DoEvents(); } browser.Print(); } This works fine when called from UI-type threads, but nothing happens when called from a service-type thread. Changing Print() to ShowPrintPreviewDialog() yields the following IE script error: Error: 'dialogArguments.___IE_PrintType' is null or not an object URL: res://ieframe.dll/preview.dlg And a small empty print preview dialog appears.

  • .NET RegEx - First N chars of First M lines

    - by George
    Hello! I want 4 general RegEx expressions for the following 4 basic cases: Up to A chars starting after B chars from start of line on up to C lines starting after D lines from start of file Up to A chars starting after B chars from start of line on up to C lines occurring before D lines from end of file Up to A chars starting before B chars from end of line on up to C lines starting after D lines from start of file Up to A chars starting before B chars from end of line on up to C lines starting before D lines from end of file These would allow to select arbitrary text blocks anywhere in the file. So far I have managed to come up with cases that only work for lines and chars separately: (?<=(?m:^[^\r]{N}))[^\r]{1,M} = UP TO M chars OF EVERY LINE, AFTER FIRST N chars [^\r]{1,M}(?=(?m:.{N}\r$)) = UP TO M chars OF EVERY LINE, BEFORE LAST N chars The above 2 expressions are for chars, and they return MANY matches (one for each line). (?<=(\A([^\r]*\r\n){N}))(?m:\n*[^\r]*\r$){1,M} = UP TO M lines AFTER FIRST N lines (((?=\r?)\n[^\r]*\r)|((?=\r?)\n[^\r]+\r?)){1,M}(?=((\n[^\r]*\r)|(\n[^\r]+\r?)){N}\Z) = UP TO M lines BEFORE LAST N lines from end These 2 expressions are equivalents for the lines, but they always return just ONE match. The task is to combine these expressions to allow for scenarios 1-4. Anyone can help? Note that the case in the title of the question, is just a subclass of scenario #1, where both B = 0 and D = 0. EXAMPLE: SOURCE: line1 blah 1 line2 blah 2 line3 blah 3 line4 blah 4 line5 blah 5 line6 blah 6 DESIRED RESULT: Characters 3-6 of lines 3-5: A total of 3 matches: <match>ne3 </match> <match>ne4 </match> <match>ne5 </match>

  • Replacing .NET WebBrowser control with a better browser, like Chrome?

    - by Sylverdrag
    Is there any relatively easy way to insert a modern browser into a .NET application? As far as I understand, the WebBrowser control is a wrapper for IE, which wouldn't be a problem except that it looks like it is a very old version of IE, with all that entails in terms of CSS screw-ups, potential security risks (if the rendering engine wasn't patched, can I really expect the zillion buffer overflow problems to be fixed?), and other issues. I am using Visual Studio C# (express edition - does it make any difference here?) I would like to integrate a good web browser in my applications. In some, I just use it to handle the user registration process, interface with some of my website's features and other things of that order, but I have another application in mind that will require more err... control. I need: A browser that can integrate inside a window of my application (not a separate window) A good support for CSS, js and other web technologies, on par with any modern browser Basic browser functions like "navigate", "back", "reload"... Liberal access to the page code and output. I was thinking about Chrome, since it comes under the BSD license, but I would be just as happy with a recent version of IE. As much as possible, I would like to keep things simple. The best would be if one could patch the existing WebBrowser control, which does already about 70% of what I need, but I don't think that's possible. I have found an activeX control for Mozilla (http://www.iol.ie/~locka/mozilla/control.htm) but it looks like it's an old version, so it's not necessarily an improvement. I am open to suggestions

  • Measuring execution time of selected loops

    - by user95281
    I want to measure the running times of selected loops in a C program so as to see what percentage of the total time for executing the program (on linux) is spent in these loops. I should be able to specify the loops for which the performance should be measured. I have tried out several tools (vtune, hpctoolkit, oprofile) in the last few days and none of them seem to do this. They all find the performance bottlenecks and just show the time for those. Thats because these tools only store the time taken that is above a threshold (~1ms). So if one loop takes lesser time than that then its execution time won't be reported. The basic block counting feature of gprof depends on a feature in older compilers thats not supported now. I could manually write a simple timer using gettimeofday or something like that but for some cases it won't give accurate results. For ex: for (i = 0; i < 1000; ++i) { for (j = 0; j < N; ++j) { //do some work here } } Now here I want to measure the total time spent in the inner loop and I will have to put a call to gettimeofday inside the first loop. So gettimeofday itself will get called a 1000 times which introduces its own overhead and the result will be inaccurate.

  • How to move/drag multiple images with CALayer???

    - by gbf.sara
    I have more than 10 images in screen and i want to move each image using CALayer concept. While am trying to move first image,its working. Even when i drag my second image also, its working. But after that when i get back to first image and when i try to move , am struck up. its not working. I dono where it went wrong. Here's ma code //Assigning Layer to UIImage// layer = [CALayer layer]; UIImage *image1 = [UIImage imageNamed:[NSString stringWithFormat:@"%@_thumb.png",[tiv imageName]]]; layer.contents = (id)image1.CGImage; layer.position=CGPointMake(200,200); layer.frame = CGRectMake(110, 180, 100, 100); [self.view.layer addSublayer:layer]; [layer needsDisplay]; [self.view.layer needsDisplay]; [layer needsLayout]; //Here i try to move my image// - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesMoved:touches withEvent:event]; NSArray *allTouches = [touches allObjects]; int count = [allTouches count]; if (count == 1) { if (CGRectContainsPoint([layer frame], [[allTouches objectAtIndex:0] locationInView:self.view])) { layer.position = [[allTouches objectAtIndex:0] locationInView:self.view]; return; } } if (count > 1) { if (CGRectContainsPoint([layer frame], [[allTouches objectAtIndex:-1] locationInView:self.view])) { layer.position = [[allTouches objectAtIndex:0] locationInView:self.view]; return; } } } Also ive planned to use single CALayer for multiple images.. When i click an image, it should be placed in that CALayer and when i click another, the same CALayer should take the latter one. So tat whenever i drag an image it should move(no matter how many images r there) . Do u think this concept will work out or is there any other idea??? My concept may seems to be a basic one. Am new to this environment n so kindly help me..

  • Go: using a pointer to array

    - by Sean
    I'm having a little play with google's Go language, and I've run into something which is fairly basic in C but doesn't seem to be covered in the documentation I've seen so far When I pass a pointer to an array to a function, I presumed we'd have some way to access it as follows: func conv(x []int, xlen int, h []int, hlen int, y *[]int) for i := 0; i<xlen; i++ { for j := 0; j<hlen; j++ { *y[i+j] += x[i]*h[j] } } } But the Go compiler doesn't like this: sean@spray:~/dev$ 8g broke.go broke.go:8: invalid operation: y[i + j] (index of type *[]int) Fair enough - it was just a guess. I have got a fairly straightforward workaround: func conv(x []int, xlen int, h []int, hlen int, y_ *[]int) { y := *y_ for i := 0; i<xlen; i++ { for j := 0; j<hlen; j++ { y[i+j] += x[i]*h[j] } } } But surely there's a better way. The annoying thing is that googling for info on Go isn't very useful as all sorts of C\C++\unrelated results appear for most search terms.

  • Spring factory beans not always initialised before being used.

    Hi, I am using spring to initialise my beans. I have configured a bean which I intend to use as a factory bean. <bean id="jsServicesFactory" class="x.y.z.JSServicesFactory" /> It is a very basic class - which has 4 getter methods. One example is public final PortletRegistry getPortletRegistry() { PortletRegistry registry = (PortletRegistry) JetspeedPortletServices .getSingleton().getService("PortletRegistryComponent"); return registry; } I have a 2nd bean which uses this factory beans to set one of its properties <bean id="batchManagerService" class="x.y.z.BatchManagerService"> ... <property name="portletRegistry"> <bean factory-bean="jsServicesFactory" factory-method="getPortletRegistry" /> </property> ... When I start my server in RAD, this all works perfectly. However when I deploy to Linux I sometimes get the following error ERROR org.springframework.web.context.ContextLoader - Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'batchManagerService' defined in ServletContext resource [/WEB-INF/context/root/batchManagerContext.xml]: Cannot create inner bean 'jsServicesFactory$created#70be70be' while setting bean property 'portletRegistry'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jsServicesFactory$created#70be70be' defined in ServletContext resource [/WEB-INF/context/root/batchManagerContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public final org.apache.jetspeed.components.portletregistry.PortletRegistry x.y.z.JSServicesFactory.getPortletRegistry()] threw exception; nested exception is java.lang.NullPointerException I have tried adding depends-on="jsServicesFactory" to my bean batchManagerService but it didn't work. Any ideas? Thanks

  • emacs: x-popup-menu max size constraints?

    - by Cheeso
    I'm working on an intellisense or code-completion capability for C#. So far, so good. Right now I have basic completion working. There are 2 ways to request completion. The first cycles through all the potential matches. The second presents a popup menu of the matches. It works for types: And also for local variables: I'm confronting two problems with x-popup-menu: the popup menu can expand to consume all available screen space, when the number of choices is large. Literally it can obscure the entire screen. The silly thing is, it's scrollable. First it expands to consume all available space, then it also becomes scrollable. Is there a way I can limit the maximum size of x-popup-menu? To specify the position of the popup menu, I pass in a position, and x-popup-menu uses that as the *middle*, not the left, of the top line of the menu. Why middle? who knows. What this means is, if I specify (40 . 60) for the location of the menu, and the menu happens to be 100 pixels wide, the menu will extend beyond the left border of the emacs window. You can see this in the 2nd image above. If I knew how wide the popup would be before specifying the position, I could compensate. But I don't. Is there a workaround? Is there a way to get x-popup-menu to take its position as the LEFT rather than the middle.

  • Looking for advice on importing large dataset in sqlite and Cocoa/Objective-C

    - by jluckyiv
    I have a fairly large hierarchical dataset I'm importing. The total size of the database after import is about 270MB in sqlite. My current method works, but I know I'm hogging memory as I do it. For instance, if I run with Zombies, my system freezes up (although it will execute just fine if I don't use that Instrument). I was hoping for some algorithm advice. I have three hierarchical tables comprising about 400,000 records. The highest level has about 30 records, the next has about 20,000, the last has the balance. Right now, I'm using nested for loops to import. I know I'm creating an unreasonably large object graph, but I'm also looking to serialize to JSON or XML because I want to break up the records into downloadable chunks for the end user to import a la carte. I have the code written to do the serialization, but I'm wondering if I can serialize the object graph if I only have pieces in memory. Here's pseudocode showing the basic process for sqlite import. I left out the unnecessary detail. [database open]; [database beginTransaction]; NSArray *firstLevels = [[FirstLevel fetchFromURL:url retain]; for (FirstLevel *firstLevel in firstLevels) { [firstLevel save]; int id1 = [firstLevel primaryKey]; NSArray *secondLevels = [[SecondLevel fetchFromURL:url] retain]; for (SecondLevel *secondLevel in secondLevels) { [secondLevel saveWithForeignKey:id1]; int id2 = [secondLevel primaryKey]; NSArray *thirdLevels = [[ThirdLevel fetchFromURL:url] retain]; for (ThirdLevel *thirdLevel in thirdLevels) { [thirdLevel saveWithForeignKey:id2]; } [database commit]; [database beginTransaction]; [thirdLevels release]; } [secondLevels release]; } [database commit]; [database release]; [firstLevels release];

  • Javascript for loop with variable

    - by Jascination
    I'm doing some simple javascript learning at the moment and I'm stuck on how to solve this problem. (the basic form comes from Code Academy). The task is to create 3 rabbit objects, each with a different adjective as an attribute. Then, print describeMyself() for each rabbit. Instead of repeating myself 3 times, I'd like to find a way to solve the problem with a for loop to make it more streamlined/challenging for myself. Here's what I tried: function Rabbit(adjective) { this.adjective = adjective; this.describeMyself = function() { console.log("I am a " + this.adjective + " rabbit"); }; } var rabbit1 = new Rabbit(fluffy); var rabbit2 = new Rabbit(happy); var rabbit3 = new Rabbit(sleepy); for (i=1; i<=3; i++){ ("rabbit"+i).describeMyself(); } Obviously, the ("rabbit"+i).describeMyself() is wrong. I want the loop to create "rabbit1", "rabbit2" and "rabbit3". What's the proper syntax here?

  • ASP.NET MVC on GoDaddy Not Working (Not Primary Domain Deployment)

    - by JPrescottSanders
    I am trying to get ASP.NET MVC working on GoDaddy and I'm not having much luck. I have read the post on SO that covers the subject, but I must have a slightly different configuration or must be missing somehting along the way because the main MVC page comes up, but all links seem to fail and no amount of tweaking the URLs seems to get it to work. A little back ground. I have a single hosting plan with many domains pointed to sub folders of the main domain. Basic ASP.NET web forms pages work just fine, but of course I wanted to try and host a sample MVC site in one of these non-primary domains. You can go to the URL here. As you can see this first page comes up, but if you click on Home or About it doesn't work. Clicking on Home creates this link "http://www.jprescottsanders.com/jps/" and clicking on about creates this link "http://www.jprescottsanders.com/jps/Home/About". As you can see JPS sneaks in there, this of course is the sub folder that i place my web app files in. I would like to know if this is a MVC related issue or a GoDaddy issue. I suspect that MVC may want to sit in the root directory of the site, and when it puts the "jps" into the URLs it breaks the routing mechanisms (but this is conjecture). I know Dan said this was possible so I'm hoping he sees this and helps me get to the bottom of this deployment strategy for MVC.
