  • problem with IBoutlet UITableView connection

    - by ideafactory
    Hi,I'm having a problem with IBoutlet UITableView connection. It seems that the IBOutlet isn't connected to the TaleView. I set the delgate and the datasource to the files owner and set the iboutlet to the tableview in the nib. The tableview is well initialized. I just want to do some reloadData and it's not working. I try to do some deselectRow just to see if it isn't reloadData problem but it doesn't deselect so i assume that the iboutlet isn't associated with my tableview. This table view is in a viewcontroller that is called as a modalViewController. Here is some code: My .h file: @interface AddEditProjectsViewController : UIViewController <UITableViewDelegate, UITableViewDataSource, UIActionSheetDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate, UITextViewDelegate, UIAlertViewDelegate>{ IBOutlet UITableView *addEditProjectTable; } @property (nonatomic, retain) IBOutlet UITableView *addEditProjectTable; @end My .m file: - (void)viewWillAppear:(BOOL)animated { (...) [addEditProjectTable reloadData]; [super viewWillAppear:animated]; Thanks for any help! :)

  • 3D World to Local transformation

    - by Bill Kotsias
    Hello. I am having a real headache trying to set a node's local position to match a given world position. I was given a solution but, AFAICS, it only takes into account orientation and position but NOT scaling : node_new_local_position = node_parent.derivedOrientation().Inverse() * ( world_position_to_match - node_parent.derivedPosition() ); The node in question is a child of node_parent; node_parent local and derived properties (orientation, position and scaling) are known, as well as its full matrix transform. All the positions are 3d vectors; the orientation is a quaternion; the full transform is a 4x4 matrix. Could someone please help me to modify the solution to support scaling in the node hierarchy? Many thanks in advance, Bill

  • How to add words to an already loaded grammar using System.Speech and SAPI 5.3

    - by Kim Major
    Given the following code, Choices choices = new Choices(); choices.Add(new GrammarBuilder(new SemanticResultValue("product", "<product/>"))); GrammarBuilder builder = new GrammarBuilder(); builder.Append(new SemanticResultKey("options", choices.ToGrammarBuilder())); Grammar grammar = new Grammar(builder) { Name = Constants.GrammarNameLanguage}; grammar.Priority = priority; _recognition.LoadGrammar(grammar); How can I add additional words to the loaded grammar? I know this can be achieved both in native code and using the SpeechLib interop, but I prefer to use the managed library. Update: What I want to achieve, is not having to load an entire grammar repeatedly because of individual changes. For small grammars I got good results by calling _recognition.RequestRecognizerUpdate() and then doing the unload of the old grammar and loading of a rebuilt grammar in the event: void Recognition_RecognizerUpdateReached(object sender, RecognizerUpdateReachedEventArgs e) For large grammars this becomes too expensive.

  • What should I learn after HTML and CSS?

    - by Ryan B
    I am 5 days into learning how to make my website, flying through my HTML & CSS book and having fun. I’m starting to consider what to order next. I’m not sure what to study next, so please give me some advice if you can. My end goal is to create a site that has a lot of the functionality that www.edufire.com and similar sites have, just for example. I think I’m learning well with the Head First Series, and the style will probably serve me well as an intro to programming. However, I don't think the books dive too deeply into any 1 subject. I could order: A: Head First Programming: A Learner’s Guide to Programming Using the Python Language B: Head First Javascript C: Head First PHP & MySQL D: a different programming book or E: another CSS or design book to solidify my basic HTML & CSS skills Any guidance would be appreciated. Thanks!

  • Create signed urls for CloudFront with Ruby

    - by wiseleyb
    History: I created a key and pem file on Amazon. I created a private bucket I created a public distribution and used origin id to connect to the private bucket: works I created a private distribution and connected it the same as #3 - now I get access denied: expected I'm having a really hard time generating a url that will work.

  • MessageBox if Recordset Update is Successful

    - by Paolo Bernasconi
    In Access 2007, I have a form to add a new contact to a table: RecSet.AddNew RecSet![Code_Personal] = Me.txtCodePersonal.Value RecSet![FName] = Me.TxtFName.Value RecSet![LName] = Me.txtLName.Value RecSet![Tel Natel] = Me.txtNatTel.Value RecSet![Tel Home] = Me.txtHomeTel.Value RecSet![Email] = Me.txtEmail.Value RecSet.Update This has worked so far, and the contact has successfully been aded. But I'm having two problems: I want to display a messagebox to tell the user the contact was successfully added If the contact was not successfully added because A contact with this name already exists A different issue Then display a message box "Contact already exists" or "error occured" respectively. My idea of doing this is: If recSet.Update = true Then MsgBox "Paolo Bernasconi was successfully added" Else if RecSet![FName] & RecSet![LName] 'already exist in table MsgBox "Contact already exists" Else MsgBox "An unknown error occured" I know this code is wrong, and obviously doesn't work, but it's just to give you an idea of what I'm trying to achieve. Thanks for all your help in advance.

  • What to look for in estimating a PowerBuilder Conversion Project?

    - by tekiegreg
    Hi there, I've been trying to do a spec for a PowerBuilder 9 to 11.5 migration of a relatively complex application. Granted PowerBuilder is not really my specialty I'm having issues trying to justify an estimate for this part of the project (and the PowerBuilder people I've been talking with have had some personal issues lately and are out of communication). These are some of the metrics that we have seen and can evaluate: -PBL Files -Main Windows -Data Windows -Functions (no we don't have the source available on this project) What metrics in particular are helpful and how long would any given "unit" such as a Data Window take?

  • TreeMap not properly returning values

    - by smessing
    I have the following TreeMap: TreeMap<String, Integer> distances = new TreeMap<String, Integer>(); and it contains both strings, "Face" and "Foo", with appropriate values, such that: System.out.println(distances); Yields: {Face=12, Foo=2} However, distances.get(Face) returns null, even though distances.get(Foo) properly returns 2. Previously, distances.get(Face) worked, but for some reason, it stopped working. Note I print out the map right before calling get() for both keys, so I haven't accidentally changed Face's value to null. Has anyone else every encountered this problem? Is there anything I can do? I'm having a terrible time simply trying to figure out how to debug this problem.

  • iPhone - how to store documents consisting of multiple images?

    - by Joe Strout
    My iPhone (actually, iPad) app creates documents that consist of several images, plus a bit of metadata. What's the best practice for storing these sorts of documents on disk? I see two main options: Create a folder for each document, and store my images as separate PNG files within the folder (plus another little file for the metadata). Create a single file which contains all images and metadata. But I'm not sure how to easily do option 2. I think I can convert my images in PNG format to/from NSData, but then what? I'm still a newbie at Cocoa, but I believe I saw something about stuffing mixed data into some NSSomethingOrOther and having this write itself out to disk, and read itself back in later. Does this ring a bell with anyone? And, will it work with large binary blobs of data like my images? Or would you recommend I simply go with option 1?

  • php encrypting an integer to get only alphanumeric characters?

    - by Matthew Steiner
    When I use some of php's encryption functions, I end up getting a few characters I don't want (+, /, =). The problem is that my application doesn't allow these in the url. I'm wondering if there's a good way of encrypting an integer and having only alphanumeric characters in the result? I'm trying to pass some data through the url. I know it's possible to do some workarounds (put data in database and pass the id to the row or something), but I really want to try it this way. Ideas?

  • Level of SVG SMIL (animation) support among the browsers

    - by user246114
    Hi, Does anyone know the current state of SVG SMIL animation support in the popular browsers? It looks like Safari, Chrome, and Opera support it. Firefox has confusing reports in their dev pages about SMIL support having been added, but I don't see it as of v3.6: https://bugzilla.mozilla.org/show_bug.cgi?id=216462 I am ignoring IE since they don't even support SVG at all, and probably never will, much less SMIL. The other thing - just comparing this test page between Safari, Chrome, and Opera: http://srufaculty.sru.edu/david.dailey/svg/ovaling.svg looks like Opera is the only one that renders it correctly. Should we not be using SMIL - kind of looks half-baked in all the browsers (sadly)? Blast. Thanks

  • AJAX call in a continuously loop?

    - by Mestika
    Hi, I want to create some kind of AJAX script or call that continuously will check a MySQL database if any new messages has arrived. When there is a new message in the database, the AJAX script should invoke a kind of alert box or message box. I’m not quite a AJAX expert (yet anyway) and have Googled around to find a solution but I’m having a hard time to figure out where to begin. I imagine that it is kind of the same method that an AJAX chat is using to see if any new chat-message has been send. I’ve also tried to search for AJAX (httpxmlrequest) call in a continuously and infinity loop but still haven’t got a solution yet. I hope there is someone, which can help me with such a AJAX script or maybe nudge me in the right direction. Thanks Sincerely Mestika

I'm not very far in and after having gotten past the C# Yield statement I'm stuck on Shared VB Array Initialisors. static IDictionary<string, Regex> countryRegex = new Dictionary<string, Regex>() { { "USA", new Regex("^[2-9]\\d{2}-\\d{3}-\\d{4}$")}, { "UK", new Regex("(^1300\\d{6}$)|(^1800|1900|1902\\d{6}$)|(^0[2|3|7|8]{1}[0- 9]{8}$)|(^13\\d{4}$)|(^04\\d{2,3}\\d{6}$)")}, { "Netherlands", new Regex("(^\\+[0-9]{2}|^\\+[0- 9]{2}\\(0\\)|^\\(\\+[0-9]{2}\\)\\(0\\)|^00[0-9]{2}|^0)([0-9]{9}$|[0-9\\- \\s]{10}$)")}, Can anyone please help me write this in VB?

  • In windbg, how do I get a heap header address from !heap -l results?

    - by Kevin
    I am playing around with windbg's !heap command, particular the "-l" switch which detects memory leaks. When -l does detect a leak, I am having problems navigating from its results to a stack trace for the source of the leak. Here is a snippet of the results from !heap -l 0:066 !heap -l Searching the memory for potential unreachable busy blocks. Entry User Heap Segment Size PrevSize Unused Flags 0324b500 0324b508 01580000 03230000 20 60 a busy 0324b520 0324b528 01580000 03230000 20 20 a busy 0324b5c8 0324b5d0 01580000 03230000 20 28 a busy Windbg's documentation for !heap tells me to use dt _DPH_BLOCK_INFORMATION with the header address, followed by dds with the blocks' StackTrace field. But the output for !heap -l doesn't specify a header address! It's only specififying Entry, User, Heap, and Segment. I've racked my brain looking over the other commands but can't figure out how to get the header address from any of these fields. Can someone help?

  • Junit vs TestNG

    - by Sam Merrell
    At work we are currently still using Junit3 to run our tests. We have been considering switching over to Junit4 for new tests being written but I have been keeping an eye on TestNG for a while now. What experiences have you all had with either Junit4 or TestNG and which seems to work better for very large numbers of tests. Having flexibility in writing tests is also important to us since our functional tests cover a wide aspect and need to be written in a variety of ways to get results. Old tests will not be re-written as they do their job just fine. What I would like to see in new tests though is flexibility in the way the test can be written, natural assertions, grouping, and easily distributed test executions.

  • Memory Profiling: How to detect which application/package is consuming too much memory

    - by malvim
    Hi, I have a situation here at work where we run a JEE server with several applications deployed on it. Lately, we've been having frequent OutOfMemoryException's. We suspect some of the apps might be behaving badly, maybe leaking, or something. The problem is, we can't really tell which one. We have run some memory profilers (like YourKit), and they're pretty good at telling what classes use the most memory. But they don't show relationships between classes, so that leaves us with a situation like this: We see that there are, say, lots of Strings and int arrays and HashMap entries, but we can't really tell which application or package they come from. Is there a way of knowing where these objects come from, so we can try to pinpoint the packages (or apps) that are allocating the most memory? Thank you in advance.

  • Asp.net 4.0 site fails because no handler mapped with Classic appPool

    - by AndyV
    When I create a Asp.net app and flip the appPool to "ASP.NET v4.0 Classic" it fails with the following error: HTTP Error 404.17 - Not Found The requested content appears to be script and will not be served by the static file handler. After some searching it seems to be the handler not mapping correctly for the Classic mode but I can't find out where or how to fix that. I have the full .Net 4.0 install with VS2010 and the app works fine if I flip the appPool to Integrated. Also, it's a Windows 7 machine (I'm having the same problem on a Vista box). Thanks in advance. Andy

  • Winforms web browser control not firing document complete with AJAX web site.

    - by ajl
    The VB.Net desktop app uses the IE browser control to navigate the web. When a normal page loads the document_complete event fires and I can read the resulting page and go from there. The issue I am having is that the page I am driving is written with AJAX, so the document complete event never fires. Furthermore, when you view the source of the page after it loaded a new portion via AJAX, it hasn't change. How are people handling this? What are my options?

  • Is it possible to use Regex through Hexadecimal to find email addresses

    - by LukeJenx
    Not sure if this is even possible but I have been looking at using Regex to get an email address that is in Hex. Basically this is to build up some of my automated forensic tools but I am having problems on making a suitable Regex algorithm. Regex for email: /^([a-z0-9_.-]+)@([\da-z.-]+).([a-z.]{2,6})$/ Hex values: @ = 40 . = 2E .com = 636f6d _ = 5f A/a = 41/61 [1] Z/z = 5a/7a - = 2d This is what I have got at the moment (it only takes into account lower case and .com). But it doesn't work! Have I messed something simple up? "/^([61-7a]+)40([61-7a]+)23(636f6d)$/" [1] I know email can only be lower case but I need to take uppercase into account too.
