  • Adding a sortcomparefunction to Dynamic Data Grid in flex

    - by Tom
    Hi, I am trying to create a dynamic datagrid in Flex 3, I have a list of columns a list of objects which correspond to datapoints for those columns which I fetch from a url. While the grid works perfectly fine the problem is that sorting on the columns is done in lexical order. I am aware that this can be fixed by adding a sortcomparefunction to a column, which is not easy for this case. I have tried doing var dgc:DataGridColumn = new DataGridColumn(dtf); f1[dtf] = function(obj1:Object, obj2:Object):int { return Comparators.sortNumeric(obj1[dtf],obj2[dtf]); }; dgc.sortCompareFunction = f1[dtf];` But the problem is that the function object that I am creating here is being overwritten in every iteration (as I am adding columns) and eventually all the columns will have sorting done only on the last column added. Suggestions please.

  • UIView or UIViewController for custom View

    - by Daniel A. White
    What is the best way to create a custom UIView that I can consume in Interface Builder? Create a custom UIView in Interface Builder and inherit from UIView in a code file, then somehow use it in another UIView ala like a control. (How do I do this?) Create a custom UIView in Interface Builder and have a custom UIViewController wire it up. In my main ViewController, place the new view. Basically, I am trying to create a reusable display view and would like a quick way to change it across all my instances with minimal effort.

  • Python regular expression implementation details

    - by Tom
    A question that I answered got me wondering: How are regular expressions implemented in Python? What sort of efficiency guarantees are there? Is the implementation "standard", or is it subject to change? I thought that regular expressions would be implemented as DFAs, and therefore were very efficient (requiring at most one scan of the input string). Laurence Gonsalves raised an interesting point that not all Python regular expressions are regular. (His example is r"(a+)b\1", which matches some number of a's, a b, and then the same number of a's as before). This clearly cannot be implemented with a DFA. So, to reiterate: what are the implementation details and guarantees of Python regular expressions? It would also be nice if someone could give some sort of explanation (in light of the implementation) as to why the regular expressions "cat|catdog" and "catdog|cat" lead to different search results in the string "catdog", as mentioned in the question that I referenced before.

  • In NHIbernate, why does SaveOrUpdate() update the Version, but SaveOrUpdateCopy() doesn't?

    - by Daniel T.
    I have a versioned entity, and this is what happens when I use SaveOrUpdate() vs. SaveOrUpdateCopy(): // create new entity var entity = new Entity{ Id = Guid.Empty }); Console.WriteLine(entity.Version); // prints out 0 // save the new entity GetNewSession(); entity.SaveOrUpdate(); Console.WriteLine(entity.Version); // prints out 1 GetNewSession(); // loads the persistent entity into the session, so we have to use // SaveOrUpdateCopy() to merge the following transient entity var dbEntity = Database.GetAll<Entity>(); // new, transient entity used to update the persistent entity in the session var newEntity = new Entity{ Id = Guid.Empty }); newEntity.SaveOrUpdateCopy(); Console.WriteLine(entity.Version); // prints out 1, but should be 2 Why is the version number is not updated for SaveOrUpdateCopy()? As I understand it, the transient entity is merged with the persistent entity. The SQL calls confirm that the data is updated. At this point, shouldn't newEntity become persistent, and the version number incremented?

  • ArcObjects - enumerating feature classes and datasets within a geodatabase

    - by Tom
    I'm trying to enumerate the contents (feature classes and feature datasets, not interested in tables, etc) of a file geodatabase using vba/arcobjects. I have the file GDB set as an IGxDatabase object, but can't find a way of getting further in. I've had a look at the geodatabase object model and tried using IFeatureClass and IFeatureDataset but neither seem to return useful results. Thanks in advance for any assistance

    - by Tom
    Ok so i change some code, re-build it and then, say for arguments sake i had a print statement outputting 'test2', well if i change it to 'test3' its still re-producing the old code 'test2'. Ive deleted the debug folder and rebuilt but no good. Then randomly about 10 builds later it will catch up. Ive also closed VS2010 and then re-opened the project but that doesnt help. What can i do as i need to see the changes asap? ps it's definitely the correct file EDIT: I've done clean and rebuild but it hasnt done anything EDIT: This is a .dll file which im modifying

  • JSP or .ascx equivalent for Scala?

    - by Daniel Worthington
    I'm working on a small MVC "framework" (it's really very small) in Scala. I'd like to be able to write my view files as Scala code so I can get lots of help from the compiler. Pre-compiling is great, but what I really want is a way to have the servlet container automatically compile certain files (my view files) on request so I don't have to shut down Jetty and compile all my source files at once, then start it up again just to see small changes to my HTML. I do this a lot with .ascx files in .NET (the file will contain just one scriptlet tag with a bunch of C# code inside which writes out markup using an XmlWriter) and I love this workflow. You just make changes and then refresh your browser, but it's still getting compiled! I don't have a lot of experience with Java, but it seems possible to do this with JSP as well. I'm wondering if this sort of thing is possible in Scala. I have looked into building this myself (see more info here: http://www.nabble.com/Compiler-API-td12050645.html) but I would rather use something else if it's out there.

  • Is preg_match safe enaught in input satinization?

    - by DaNieL
    Im building a new web-app, LAMP environment... im wondering if preg_match can be trusted for user's input validation (+ prepared stmt, of course) for all the text-based fields (aka not html fields; phone, name, surname, etc..). For example, for a classic 'email field', if i check the input like: $email_pattern = "/^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)" . "|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}" . "|[0-9]{1,3})(\]?)$/"; $email = $_POST['email']; if(preg_match($email_pattern, $email)){ //go on, prepare stmt, execute, etc... }else{ //email not valid! do nothing except warn the user } can i sleep easy against the sql/xxs injection? I write the regexp to be the more restrictive as they can.

  • Nav Controller, UITableViewController, UITextField to become firstResponder?

    - by Daniel Granger
    I have a core data application which uses a navigation controller to drill down to a detail view and then if you edit one of the rows of data in the detail view you get taken to an Edit View for the that single line, like in Apples CoreDataBooks example! The edit view is a UITableviewController which creates its table with a single section single row and a UITextfield in the cell, programatically. What I want to happen is when you select a row to edit and the edit view is pushed onto the nav stack and the edit view is animated moving across the screen, I want the textfield to be selected as firstResponder so that the keyboard is already showing as the view moves across the screen to take position. Like in the Contacts app or in the CoreDataBooks App. I currently have the following code in my app which causes the view to load and then you see the keyboard appear (which isn't what I want, I want the keyboard to already be there) - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [theTextField becomeFirstResponder]; } You can't put this in -viewWillAppear as the textfield hasn't been created yet so theTextField is nil. In the CoreDataBooks App where they achieve what i want they load there tableview from a nib so they use the same code but in -viewWillAppear as the textfield has already been created! Is there anyway of getting around this without creating a nib, I want to keep the implementation programatic to enable greater flexibility. Many Thanks

  • Taking video from video camera and displaying it with MPMoviePlayerController IPhone SDK

    - by Daniel
    Has anyone tried taking a video from the camera and then using the video player provided to play it? When you take the video in portrait mode, sometimes the movie will play (when the player puts it in landscape mode) and when it puts it in portrait mode you cannot view the movie all you hear is sound,sometimes in landscape mode is flickers and does not play right, has anyone encountered this and found a way to fix it? My code to play the video looks like this: - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { NSURL *urls=[info objectForKey:@"UIImagePickerControllerMediaURL"] ; moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[info urls]]; if (moviePlayer) { [moviePlayer play]; } } I checked settings on the docs nothing seems like it would fix this...Thanks

  • http://java.sun.com/j2se/1.4.2/docs/api/org/w3c/dom/Document.html#getDoctype()

    - by Tom Brito
    The Document class have a getDoctype method but doesn't have a setDoctype. The documentation says: The DOM Level 2 does not support editing the Document Type Declaration. docType cannot be altered in any way, including through the use of methods inherited from the Node interface, such as insertNode or removeNode. and in my project I need to generate xml files with my specified doctypes. I've tryied to create my own DefaultNode, but it throws "DOMException: Method not supported" for the setters. Any idea?

  • Is there a detailed description of optimizations in the Android build process?

    - by Daniel Lew
    I've been curious as to all the optimizations that go into the building of an .apk. I'm curious because of two things I've tried in the past to bring down the size of my .apk: I have had a few large json assets in projects before, as well as a static sqlite database. I tried bringing down the size of the apk by gzipping them before the build process, but the resulting size is exactly the same. I just today tried pngcrush on my /drawable/ folders. The resulting build was exactly the same size as before. I would think that perhaps #1 could be explained by the zip process, but simply zipping the /drawable/ folders in #2 result in different-sized files. Perhaps the build process runs something akin to pngcrush? Regardless, I was wondering if anyone knew where to find a detailed description of all the optimizations in the Android build process. I don't want to waste my time trying to optimize what is already automated, and also I think it'd help my understanding of the resulting apk. Does anyone know if this is documented anywhere?

  • Where are Eclipse Bookmarks stored?

    - by Tom Tresansky
    Does anyone know where bookmarks are stored in the Eclipse IDE? I had to delete a Java project from my workspace, then use the Import Existing project option to reset some configuration settings, and now my bookmarks are gone. I'm trying to understand how this affected my bookmarks, since everything on the file system except for the Eclipse .project and .classpath files should have remained unchanged.

  • In ExtJS, how do I place two fieldsets side-by-side in a panel with a hbox layout?

    - by Daniel T.
    In ExtJS, I'm having a little trouble placing two fieldsets side-by-side in a panel with a hbox layout. The hbox layout seems to be unaware of the fieldset's height, and cuts it off, even if I explicitly set the panel's height to something large. Here's what it looks like: The blue border is the hbox panel, and there's 2 fieldsets inside, 'Client Info' and 'Owner Info'. The code is like so (simplified and runnable in Firebug): var clientInfo = { xtype: 'fieldset', defaultType: 'textfield', title: 'Client Info', items: [ { fieldLabel: 'First Name' }, { fieldLabel: 'Last Name' }, { fieldLabel: 'Cell Phone #' }, { fieldLabel: 'Work Phone #' } ] }; var ownerInfo = { xtype: 'fieldset', defaultType: 'textfield', title: 'Owner Info', items: [ { fieldLabel: 'First Name' }, { fieldLabel: 'Last Name' }, { fieldLabel: 'Cell Phone #' }, { fieldLabel: 'Work Phone #' } ] }; new Ext.Panel({ layout: 'hbox', frame: true, height: 400, width: 800, defaults: { flex: 1 }, items: [ clientInfo, ownerInfo ] }).render(document.body); P.S. If you remove defaults: { flex: 1 }, the fieldsets render correctly, but doesn't automatically resize to fit the container, which is something I need. Does anybody know how to fix this rendering issue? Thanks.

  • Specific checkboxes checked in symfony 1.4

    - by Tom
    Hi, I'm able to do the following for all checkboxes in a set (in an action): $this->form->getWidget('some_form_field')->setAttribute('checked', 'checked'); ... but I'm unable to set specific checkboxes to ticked on the basis of data returned from the db. I'm after something like: $this->form->getWidget('some_form_field')->setAttributes(array(....)); ... where I can refer to the specific checkboxes to be ticked somehow, or pass an array to it. There's nothing in the symfony documentation on this specifically and I've had enough of trying a dozen combinations to get it work. Any help would be appreciated. Thanks.

  • What is the coolest thing you can do in <10 lines of simple code? Help me inspire beginners!

    - by Tom Ritter
    I'm looking for the coolest thing you can do in a few lines of simple code. I'm sure you can write a Mandelbrot set in Haskell in 15 lines but it's difficult to follow. My goal is to inspire students that programming is cool. We know that programming is cool because you can create anything you imagine - it's the ultimate creative outlet. I want to inspire these beginners and get them over as many early-learning humps as I can. Now, my reasons are selfish. I'm teaching an Intro to Computing course to a group of 60 half-engineering, half business majors; all freshmen. They are the students who came from underprivileged High schools. From my past experience, the group is generally split as follows: a few rock-stars, some who try very hard and kind of get it, the few who try very hard and barely get it, and the few who don't care. I want to reach as many of these groups as effectively as I can. Here's an example of how I'd use a computer program to teach: Here's an example of what I'm looking for: a 1-line VBS script to get your computer to talk to you: CreateObject("sapi.spvoice").Speak InputBox("Enter your text","Talk it") I could use this to demonstrate order of operations. I'd show the code, let them play with it, then explain that There's a lot going on in that line, but the computer can make sense of it, because it knows the rules. Then I'd show them something like this: 4(5*5) / 10 + 9(.25 + .75) And you can see that first I need to do is (5*5). Then I can multiply for 4. And now I've created the Object. Dividing by 10 is the same as calling Speak - I can't Speak before I have an object, and I can't divide before I have 100. Then on the other side I first create an InputBox with some instructions for how to display it. When I hit enter on the input box it evaluates or "returns" whatever I entered. (Hint: 'oooooo' makes a funny sound) So when I say Speak, the right side is what to Speak. And I get that from the InputBox. So when you do several things on a line, like: x = 14 + y; You need to be aware of the order of things. First we add 14 and y. Then we put the result (what it evaluates to, or returns) into x. That's my goal, to have a bunch of these cool examples to demonstrate and teach the class while they have fun. I tried this example on my roommate and while I may not use this as the first lesson, she liked it and learned something. Some cool mathematica programs that make beautiful graphs or shapes that are easy to understand would be good ideas and I'm going to look into those. Here are some complicated actionscript examples but that's a bit too advanced and I can't teach flash. What other ideas do you have?

  • Why is 1px sometimes 2px when specified in Android XML?

    - by Daniel Lew
    I've got a desire for a one-pixel divider line, just for looks. I thought I could accomplish this using a View of height 1px, with a defined background. However, I'm getting some very odd behavior on different devices - sometimes the 1px ends up as 2px. Take this sample layout for example: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <View android:layout_width="fill_parent" android:layout_height="1px" android:background="@android:color/white" android:layout_marginBottom="4dp" /> <View android:layout_width="fill_parent" android:layout_height="1px" android:background="@android:color/white" android:layout_marginBottom="4dp" /> <View android:layout_width="fill_parent" android:layout_height="1px" android:background="@android:color/white" android:layout_marginBottom="4dp" /> <View android:layout_width="fill_parent" android:layout_height="1px" android:background="@android:color/white" android:layout_marginBottom="4dp" /> <View android:layout_width="fill_parent" android:layout_height="1px" android:background="@android:color/white" android:layout_marginBottom="4dp" /> <View android:layout_width="fill_parent" android:layout_height="1px" android:background="@android:color/white" android:layout_marginBottom="4dp" /> <View android:layout_width="fill_parent" android:layout_height="1px" android:background="@android:color/white" android:layout_marginBottom="4dp" /> </LinearLayout> When run on my G1, this comes out fine. But on the Nexus One, it alternates between 1px lines and 2px lines. Does anyone know where this is going awry? Why does Android sometimes make 1px into 2px?

  • Upper extension method in linq to NHibernate

    I would like to use the Upper extension method which is declared on the IDbMethods interface against Sql Server 2008. I understand that this will translate to UPPER() on sql server. However I can not figure out how to get an implementation of IDbMethods so that I can use the extension method.

  • Numbered list in Report Builder export to word

    - by Daniel
    I have created a SQL Server Reporting Services Report Builder 3 report that contains a list of several items from a SharePoint list. I would like the list on the report to be a numbered list, so that when exported to Word, if a user adds another item to the document, the numbering is updated automatically. I can simulate a numbered list by creating a table and using 'RowNumber' in one of the columns, however this does not get rendered as a true numbered list. Is there any way to create a true numbered list in Report Builder 3

    I am new to .NET, and don't have much experience in programming. What is the standard way of handling user authentication in .NET in the following situation? 1.In Process A, User inputs ID/Password 2.Process A sends the ID/Password to Process B over a nonsecure public channel. 3.Process B authenticates the user with the recieved ID/Password what are some of the standard cryptographic algorithms I can use in above model? The users(customers that bought my company's software) will be running the software(Process A) locally in their computer(connected to internet). I need to authenticate the users so that only registered users can run the program. Thank You!

  • Diff Algorithm

    - by Daniel Magliola
    I've been looking like crazy for an explanation of a diff algorithm that works and is efficient. The closest I got is this link to RFC 3284 (from several Eric Sink blog posts), which describes in perfectly understandable terms the data format in which the diff results are stored. However, it has no mention whatsoever as to how a program would reach these results while doing a diff. I'm trying to research this out of personal curiosity, because I'm sure there must be tradeoffs when implementing a diff algorithm, which are pretty clear sometimes when you look at diffs and wonder "why did the diff program chose this as a change instead of that?"... Does anyone know where I can find a description of an efficient algorithm that'd end up outputting VCDIFF? By the way, if you happen to find a description of the actual algorithm used by SourceGear's DiffMerge, that'd be even better. NOTE: longest common subsequence doesn't seem to be the algorithm used by VCDIFF, it looks like they're doing something smarter, given the data format they use. Thanks!

  • iPhone programming - problem with CoreFoundation forking, PLEASE for the love of god help! lol

    - by Tom
    Hello all, I've been working on an iPhone for several months. It's a 2d shooting game akin to the old Smash TV type games. I'm doing everything alone and it has come out well so far, but now I am getting unpredictable crashes which seem to be related to CoreFoundation forking and not exec()ing, as the message THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONA LITY_YOU_MUST_EXEC__ always shows up somewhere in the debugger. Usually it shows up around a CFRunLoopRunSpecific and is related to either a timer firing or _InitializeTouchTapCount. I cannot figure out exactly what is causing the fork to occur. My main game loop is running on a timer, first updating all the logic and then drawing everything with openGL. There is nothing highly complex or unusual. I understand you cannot make CF calls on the childside of a fork, or access shared memory and things like that. I am not explicitly trying to fork anything. My question is: can anyone tell me what type of activity might cause CoreFoundation to randomly fork like this? I'd really like to finish this game and I don't know how to solve this problem. Thanks for any help.
