  • Problem with Scrolling UITableView

    - by HiGuy Smith
    Hello, I have a navigation-based application that has a scrolling UITableView filled with the contents of a directory. Somehow, when I try to scroll a new cell into view, the application crashes. I have determined that it goes down to these lines of code in - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {: NSString *cellText = [contentArray objectAtIndex:indexPath.row]; cell.textLabel.text = cellText; Now why this is crashing, I don't know. contentArray is a NSArray with the table data. If you need a bit more code to tell: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [contentArray count]; } Please help me with this problem, HiGuy

  • Compare values for audit trail

    - by kagaku
    I'm attempting to develop an audit trail/tracking solution for an existing database written in PLSQL/PHP - however I'm still unsure as of yet on an easy (to implement and maintain) solution for tracking changes to fields/values. For instance, the project tracking portion of the DB APP tracks over 200 fields and ideally I'd like a nice way to show a history of changes, such as: 5/10/2010 - Project 435232 updated by John Doe Changed Project Name (Old: Test Project; New: Super Test Project) Changed Submission Date (Old: 5/10/2010; New: 5/11/2010) Changed Description (Old: This is an example!; New: This is a test example) Essentially for each field (db column) it would output a new line to show the old/new values. So far my current idea is saving the current version of the data to a temporary table, updating the primary table with the new data then loading each row into an array and doing an array compare to determine the differences. This seems a bit convoluted, and if there is an easier method I'd love to know it. Any ideas or suggestions are much appreciated!

  • Performance Counters in Server Development

    - by Mubashar Ahmad
    Dear Gurus All you be agree with the value and worth of Performance Counters while developing and maintaining a server kind application I would like to know what is the best way to implement those, Specifically using C#? Usually performance counters have the following attributes They are shared global Writing requires locks to ensure Synchronization Reading Some times requires locks too. Is it better to update them Asynchronously and what is the best way to make them so. (I am planning to use the ThreadPool.QueuWorketItem function, pls tell me you opinion on this too.) If my question seems a bit vague can you just take the example of a HelloWorld Wcf service and i wanted to know following how many times its being hit overall and within a certain period Average/min/max Response Times overall and within a certain period. Moreover if any one knows about the Specialized way provided by DotNet or WCF then please let me know as well.

  • Mercurial - revert back to old version and continue from there

    - by Paolo
    I'm using mercurial locally for a project (it's the only repo there's no pushing/pulling to/from anywhere else). To date it's got a linear history. However, the current thing I'm working on I've now realised is a terrible approach and I want to go back to the version before I started it and implement it a different way. I'm a bit confused with the branch / revert / update -C commands in Mercurial. Basically I want to revert to version 38 (currently on 45) and have my next commits have 38 as a parent and carry on from there. I don't care if revisions 39-45 are lost for ever or end up in a dead-end branch of their own. Which command / set of commands do I need?

  • How can I determine if jquery tab is shown because of user click or from tab rotation

    - by Richard Edwards
    I've been using the jQuery UI tabs for a bit now and an interesting request has come up. The current tab setup is using the rotation feature. I need to find a way to determine if the tab is shown because of the result of the rotation itself, or because a user physically clicked the tab. I've wired up all of the standard events, show and select and they fire regardless of the source of the tab change. Does anyone have any ideas? Basically I'd like to do something additional if the user clicked the tab, but not if the tab changes by itself via the rotation. If I wire up the click even to the tabs themselves it doesn't seem to get fired at all, I'm assuming because the tabs widget is using that event itself.

  • pasteHTML removes markup

    - by ullmark
    I am writing a plugin to an old IE-only WYSIWYG-editor which resides in an old CMS. I've created a plugin that opens an popup where the user kan enter the url of an youtube clip. The popup then creates the corrent <object..><param..> markup for the embed and uses Internet Explorers pasteHTML function; var range = plugin.editorDocument.selection.createRange(); var embedHtml = OpenDialog(dialogUrl, null, 400, 200); if (!embedHtml) { return; } range.pasteHTML(embedHtml); I know it's missing a bit of information about some of the variables but you get the picture. The problem is that the <param>-tags gets removed when i run the pasteHTML. I wonder if anyone have an idea of fixing this, and letting me keep my param-tags

  • Injecting an XML fragment into the current document from an external file

    - by makenai
    I'm currently parsing an XML file using REXML and trying to come up with a way of inserting an XML fragment from an internal file. Currently, I'm using some logic like the following: doc.elements.each('//include') do |element| handleInclude( element ) end def handleInclude( element ) if filename = element.attributes['file'] data = File.open( filename ).read doc = REXML::Document.new( data ) element.parent.replace_child( element, doc ) end end Where my XML looks like the following: <include file="test.xml" /> But this seems a little bit clunky, and I'm worried that REXML might not always parse XML fragments correctly due to absence of a proper root node in some cases. Is there a better way of doing this? Concern #2: REXML seems not to pick up my changes after I replace elements. For example, after making a change: doc.elements.each('rootNode/*') do |element| end ..picks up neither the original element I replaced, nor the one I replaced it with. Is there some trick to getting REXML to rescan its' tree?

  • Visual Studio 2010 Database Projects: Are there any videos/tutorials or comments about the new Datab

    - by Mark Redman
    I have recently upgraded to Visual Studio 2010. I have kept database projects separate to application projects. The database project was converted from and old DPR project and added a whole lot of additional folder. I deleted those, but now I suspect I need to recreate the project as these new projects work very differently. Now that I have need to update scripts, it seems I can even paste new SQL files into the project so am a bit stuck. Are there any tutorials / walkthrough that show the basics on starting and creating a database project? Or even better a video? Also if there are any tips and tricks or comments on this, I will be happy to hear them?

  • Jquery autocomplete for input form, using Textpattern category list as a source

    - by John Stephens
    I'm using the Textpattern CMS to build a discussion site-- I have a firm grasp of XHTML and CSS, as well as Textpattern's template language, but PHP and Javascript are a bit beyond my cunning. On the input form to begin a new topic, users need to select a category from a list of over 5,000 options. Using the HTML select-type input element is very unwieldy, but it works. I would like to use some kind of Javascript magic to display a text-type input element that will read user input and display matches or autocomplete from the available categories, passing the required option's value into the appropriate database field. I've seen several autocomplete plugins for jquery, but the instructions presuppose that you understand how Javascript works. As I mentioned above, it's easy for me to generate the category list as a select-type input element, and I can hide that element using CSS. Is it possible to control select-list input using an autocomplete mechanism in a text-type input element? How would I do that?

  • Need help with foreach and XML

    - by danit
    I have the following output (via link) which displays the var_dump of some XML im generating: http://bit.ly/aoA3qY At the very bottom of the page you will see some output, generated by this code: foreach ($xml->feed as $entry) { $title = $entry->title; $title2 = $entry->entry->title; } echo $title; echo $title2; For some reason $title2 only outputs once, where there are multiple entries? Im using $xml = simplexml_load_string($data); to create the xml.

  • DB Design Question

    - by hazimdikenli
    I am designing an Org Chart, model is almost ready and simplified a bit for clarity here. OrgUnit (OrgUnitId, Name, ReportsToOrgUnitId, ...) OrgUnitJobs (OrgUnitJobId, OrgUnitId, JobName, ReportsToOrgUnitJobId, ... ,IsJobGroup) Employee (EmployeeId, ........) OrgUnitJobEmployee (OrgUnitJobId, EmployeeId, AssignedDate, .....,) so I want to know every OrgUnit's ManagerEmployee (should have one), and Employees can have more than one job, but one of them has to be the main job, so I know whats his manager and other stuff. This is going to support a little workflow behind the scnese, so that is why it is not a very simple Org chart Model. so what would you do, would you add properties like (IsManager property to OrgUnitJobs model) or add ManagerOrgUnitJobId to OrgUnitModel. and why? Likewise, for employees would you add IsPrimaryJob property to OrgUnitJobEmployee model, or add PrimaryJobId to Employee Model.

  • Find what unknown function does in C using gdb

    - by Gary
    Hi, I have a function m(int i, char c) which takes and returns a char between "-abc...xyz" and also takes an integer i. Basically I have no way to see the source code of the function but can call it and get the return value. Using gdb/C, what's the best way to decipher what the function actually does? I've tried looking for patterns using consecutive chars and integer inputs but have come up with nothing yet. If it helps, here are some results of testing the return values, with the first two bits being the arguments and the last bit being the return value: 0 a i 0 b l 0 c t 0 d x 0 e f 0 f v 1 a q 1 b i 1 c y 1 d e 2 a a 2 b y 2 c f 2 d n

  • A Question About Embedding HTML In PHP

    - by Brian
    Hello all Some time ago I read a posting on a board where the person was talking poorly about people that have HTML embedded/within their PHP. I do quite a bit of PHP development but I still interleave HTML and PHP in the same document. Is there a better way to do this, am I doing it wrong? I know that in JSP/JSF they use an XML document with namespaces to insert their HTML code so I was wondering if there was a similar function that PHP uses that I should be taking advantage of. Thanks for taking the time to read. :-)

  • How to read a file byte by byte in Python and how to print a bytelist as a binary?

    - by zaplec
    Hi, I'm trying to read a file byte by byte, but I'm not sure how to do that. I'm trying to do it like that: file = open(filename, 'rb') while 1: byte = file.read(8) # Do something... So does that make the variable byte to contain 8 next bits at the beginning of every loop? It doesn't matter what those bytes really are. The only thing that matters is that I need to read a file in 8-bit stacks. EDIT: Also I collect those bytes in a list and I would like to print them so that they don't print out as ASCII characters, but as raw bytes i.e. when I print that bytelist it gives the result as ['10010101', '00011100', .... ]

  • Mac OS X: java.lang.ClassNotFoundException: com.sun.java.browser.plugin2.DOM

    - by Thilo
    I am trying to use the new LiveConnect features introduced in Java 6 Update 10. Code looks like this (copied from the applet tutorial): Class<?> c = Class.forName("com.sun.java.browser.plugin2.DOM"); Method m = c.getMethod("getDocument", java.applet.Applet.class); Document document = (Document) m.invoke(null, this); But all I am getting is a ClassNotFoundException for the entry-point class. This on the Mac, 10.6, with both Firefox and Safari. Java Plug-in 1.6.0_22 Using JRE version 1.6.0_22-b04-307-10M3261 Java HotSpot(TM) 64-Bit Server VM Is this not implemented on the Mac? Or do I need to configure something? All I need to do is get and set the value of form elements on the page, so I would be fine with an older (pre-6u10) API if that works better.

  • Understanding pattern matching with cons operator

    - by Mathias
    In "Programming F#" I came across a pattern-matching like this one (I simplified a bit): let rec len list = match list with | [] -> 0 | [_] -> 1 | head :: tail -> 1 + len tail;; Practically, I understand that the last match recognizes the head and tail of the list. Conceptually, I don't get why it works. As far as I understand, :: is the cons operator, which appends a value in head position of a list, but it doesn't look to me like it is being used as an operator here. Should I understand this as a "special syntax" for lists, where :: is interpreted as an operator or a "match pattern" depending on context? Or can the same idea be extended for types other than lists, with other operators?

  • Convert Hexadecimal String to Data

    - by AriX
    Hi Stack Overflow, I have found a whole lot of different solutions to this problem, but not all of them work, and a lot of them seem somewhat hacky and inefficient. Basically I have a string of hexadecimal data (i.e. "55 AA 41 2A 00 94 55 AA BB BB 00 FF") which I would like to convert to raw data. What is the best way to do this? UPDATE: Vicky's solution worked great for me, but I changed it to work with hexadecimal strings that don't have spaces in between and changed the style a bit. int i = 0; char *hexString = "55AA412A009455AABBBB00FF" char *hexPtr = hexString; unsigned int *result = calloc(strlen(hexString)/2 + 1, sizeof *result); while (sscanf(hexPtr, "%02x", &result[i++])) { hexPtr += 2; if (hexPtr >= hexString + strlen(hexString)) break; } return result;

  • C++ defines for a 'better' Release mode build in VS

    - by darid
    I currently use the following preprocessor defines, and various optimization settings: WIN32_LEAN_AND_MEAN VC_EXTRALEAN NOMINMAX _CRT_SECURE_NO_WARNINGS _SCL_SECURE_NO_WARNINGS _SECURE_SCL=0 _HAS_ITERATOR_DEBUGGING=0 My question is what other things do fellow SOers use, add, define, in order to get a Release Mode build from VS C++ (2008,2010) to be as performant as possible? btw, I've tried PGO etc, it does help a bit but nothing that comes to parity, also I'm not using streams, the C++ i'm talking about its more like C but making use of templates and STL algorithms. As it stands now very simple code segments flop when compared to what GCC produces on say an equivalent x86 machine running linux (2.6+ kernel) using 02. Side-Note: I believe a lot of the issues relate directly to the STL version (Dinkum) provided by MS. Could people please elaborate on experiences using STLPort etc with VS C++.

  • iPhone: Best Method for Passing Data to and from a Server

    - by SAPNA
    I am developing an iPhone application that downloads data from a website. The website database is implemented in SQL and the site itself uses the classic ASP interface. I am unsure as to which method would be best for transferring data to and from the server. Both JSON and SOAP require XML processing and I'm not sure how that affects performance or which of those two is best. What would be the best method in general for data transfer given the server configuration we currently have? I very new to this field and I'm a bit confused. Any help would be appreciated.

  • What is the best jQuery based window plug-in you have ever used?

    - by Emre Sevinç
    I tried a couple of jQuery based window plug-ins but unfortunately was not satisfied with any of them. Here's what I tried: http://hernan.amiune.com/labs/jQuery-Windows-Engine-Plugin/jQuery-Windows-Engine-Plugin.html http://fstoke.me/jquery/window/ http://www.soyos.net/aerowindow-jquery.html I need following features without any compromises: Maximize, minimize (to a reasonable location such as bottom-left corner, not in the middle of the screen), drag, resize, etc. Highly and easily configurable Actively developed (this can be relaxed a little bit) Comes with good documentation (and examples) works cross-browser (I had problems in IE when I tried to use fstoke.me's implementation). The three plug-ins I have tried failed in one or more respects. I'm not looking for very fancy, animated effects, just very basic but yet adequate functionality. Any suggestions?

  • Enhanced Podcasts and MPMoviePlayerViewController

    - by Ben Robinson
    Hi, This is a bit of an odd/specific one - possibly a bug? I'm using MPMoviePlayerViewController to play a variety of files, including Enhanced Podcasts - these are audio files, but with a slideshow of images, often created using GarageBand. Until (i think) iOS 3.2 they weren't supported at all, now they are and play fine in the iPod app, but in my app the slideshow doesn't start, the full screen movie player opens, and the audio begins, but all I see is the QuickTime logo. If I scrub the track the pictures appear - and will continue to play correctly - but I see nothing if I don't scrub! Any ideas?? On a related note, these files also include a small rectangluar button containing an (i) button on the right hand side - anybody know what it is or should do?! It does nothing for me!
