  • iPhone: UITextField inside TableView cell?

    - by Nic Hubbard
    I am trying to programatically add a UITextFiled inside one of my tableview cells. How would I do this? Assuming it is in the following method, what code would I use? - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:CellIdentifier] autorelease]; cell.editingAccessoryType = UITableViewCellAccessoryDisclosureIndicator; // Don't let the user click when not in editing mode cell.selectionStyle = UITableViewCellSelectionStyleNone; } switch (indexPath.row) { case 0: cell.textLabel.text = @"Title"; // This is where I want to add a text field cell.detailTextLabel.text = @"test"; cell.editing = YES; break; } return cell; }

  • MVC2: "File not found" after view is painted

    - by Dave Hanna
    This is wierd. First, I'm building a site based on someone else's framework (Piers Lawson: Creating a RESTful Web Service using MVC ), so I'm not entirely sure what's going on under the covers. But when I run it in VS 2010 by pressing F5, it brings up the Home page, and THEN traps an error in Application_Error. The error is "File does not exist" exception. But I have no idea what file it's looking for. Where does flow control go after the View is finished displaying? How can I break to find out what it's looking for?

  • Using 2 JQuery Autocomplete

    - by Trike
    Hi All! I am using the JQuery Autocomplete Plugin 1.1. When I try to add autocomplete to 2 inputs in this way: $("#object_ac").autocomplete("autocomplete_search.php", { extraParams: {object:1}, width: 160, selectFirst: false, minChars: 2 }); $("#id_norm_doc_ac").autocomplete("autocomplete_search.php", { width: 460, selectFirst: false, mustMatch: true }); $("#id_norm_doc_ac").result(function(event, data, formatted) { $("#id_norm_doc_add").val(data[1]); }); When #object_ac selected before #id_norm_doc_ac I get error after selecting one of suggestions in #id_norm_doc_ac: data is undefined [Break on this error] data = elementToString(data.documentElement, true); If I select #id_norm_doc_ac before other inputs, everything goes normal. Thanks in advance for any assistance!

  • Safest way to copy a file

    - by aron
    Hello, I need to merg two PDF files. However sometimes a file might be locked up I wrote this code, but I'm wondering if it's not the smartest solution: private static int FILE_LOCKED_WAIT_PERIOD = 1000; while (true) { // If the file is in use, IOException will be thrown. // If file is not permitted to be opened because of Permission // Restrictions, UnauthorizedAccessException will be thrown. // For all other, Use normal Exception. try { inputDocument1 = PdfReader.Open(fileToMerge, PdfDocumentOpenMode.Import); break; } catch (IOException) { Thread.Sleep(FILE_LOCKED_WAIT_PERIOD); } catch (UnauthorizedAccessException) { Thread.Sleep(FILE_LOCKED_WAIT_PERIOD); } catch (Exception) { Thread.Sleep(FILE_LOCKED_WAIT_PERIOD); } }

  • Can Cython compile to an EXE?

    - by ThantiK
    I know what Cythons purpose is. It's to write compilable C extensions in a Python-like language in order to produce speedups in your code. What I would like to know (and can't seem to find using my google-fu) is if Cython can somehow compile into an executable format since it already seems to break python code down into C. I already use Py2Exe, which is just a packager, but am interested in using this to compile down to something that is a little harder to unpack (Anything packed using Py2EXE can basically just be extracted using 7zip which I do not want) It seems if this is not possible my next alternative would just be to compile all my code and load it as a module and then package that using py2exe at least getting most of my code into compiled form, right?

  • [C#] how do I get the height of a rich text content after word wrap?

    - by Led
    Question A. Given 1. A string in rich text format that may have paragraph, tabs, space, line break, indentation, (or even image?) 2. A width for the word wrapping rich text control/editor How do I know the height of the content after it have performed all the word wrapping? Is there something like int MeasureRichTextHeightAfterWordWrap(string aRichTextContent, int aWidth)? Otherwise how does those rich text control know how much to autosize? Do I have to actually place the content on a dummy rich text control and get its height afterwards? Question B. Similar to question A but in plain text onto a plain text memo/control/editor. And manually draw string with manually calculated indentations, breaks, word wrappings. Is it easier or harder?

  • Null object that is not null

    - by Guillaume
    Hello, I use 2 threads to act like a produce/consumer using double queue (http://www.codeproject.com/KB/threads/DoubleQueue.aspx). Sometimes in my 2nd thread, I get an object that is NULL but it should not be as I filled it in the first thread. I tried this: if(myObject.Data == null) { Console.WriteLine("Null Object") // <-- Breakpoint here } When I my break point hits, I can watch myObject.Data and indeed it's NULL, but when I hit F10 and then go to the next line (which is } ) myObject.Data is not NULL. I also added a lock on myObject before if .... to be sure that no one whould use this object. How is that possible and what can I do ?

  • Advanced Array Sorting in Ruby

    - by Ruby Beginner
    I'm currently working on a project in ruby, and I hit a wall on how I should proceed. In the project I'm using Dir.glob to search a directory and all of its subdirectories for certain file types and placing them into an arrays. The type of files I'm working with all have the same file name and are differentiated by their extensions. For example, txt_files = Dir.glob("**/*.txt") doc_files = Dir.glob("**/*.doc") rtf_files = Dir.glob("**/*.rtf") Would return something similar to, FILECON.txt ASSORTED.txt FIRST.txt FILECON.doc ASSORTED.doc FIRST.doc FILECON.rtf ASSORTED.rtf FIRST.rtf So, the question I have is how I could break down these arrays efficiently (dealing with thousands of files) and placing all files with the same filename into an array. The new array would look like, FILECON.txt FILECON.doc FILECON.rtf ASSORTED.txt ASSORTED.doc ASSORTED.rtf etc. etc. I'm not even sure if glob would be the correct way to do this (all the files with the same file name are in the same folders). Any help would be greatly appreciated!

  • How to get hold of the current NHibernate.Cfg.Configuration instance.

    - by Sandor Drieënhuizen
    My C# project has repositories that are instantiated using dependency injection. One of the repository methods needs access to the NHibernate.Cfg.Configuration instance (to generate the database schema) that was returned when initializing NHibernate. I cannot pass the configuration to the repository however, because that would break the persistence ignorance principle -- I really don't want to expose any implementation details through the repository interface. So what I'm looking for is a way of getting hold of the current NHibernate.Cfg.Configuration instance from within my repository. I have no trouble getting hold of the current session, it's just the configuration that I cannot get hold of.

  • How do you find time for improving your programming skills?

    - by Snehal
    I'm a Java/J2ee programmer working in India. I'm very passionate about programming and I constantly strive to hone my programming skills by reading blogs, solving Project euler questions, learning new technologies, developing small apps etc;. But I find it very difficult to manage my time. Working for 12 hrs a day in office leaves me stressed out and spend my weekends with my family. So i hardly have like 5-6 hrs per week to actually work on something of my interest which will help me improve. How do you manage time so that you find time to improve your current standing? EDIT: 12 hours includes 1hour of travel & 1 hr of break(lunch/coffee). Effectively I work for 10 hours per day in office which is mandated by my organization. -Snehal

    - by Buffernet
    I'm in xcode debugging my iphone application. when i get to a break point and I roll over my object and properties of that object say "out of scope" instead of their respective values.

  • FileNotFound exception when trying to write to a file

    - by Chris Knight
    OK, I'm feeling like this should be easy but am obviously missing something fundamental to file writing in Java. I have this: File someFile = new File("someDirA/someDirB/someDirC/filename.txt"); and I just want to write to the file. However, while someDirA exists, someDirB (and therefore someDirC and filename.txt) do not exist. Doing this: BufferedWriter writer = new BufferedWriter(new FileWriter(someFile)); throws a FileNotFoundException. Well, er, no kidding. I'm trying to create it after all. Do I need to break up the file path into components, create the directories and then create the file before instantiating the FileWriter object?

  • What HTML is permitted within Flash text fields.

    - by JasonS
    Hi, Could someone clarify for me what input Flash accepts for its text fields? I am tasked with managing a content management system, this then generates XML which power's flash sites. I have nothing to do with Flash. I work with PHP. Currently we use a rather temperamental Flash Text Editor which is prone to all sorts of troubles. I tried to plug-in tinyMce but it broke the Flash templates. I then recently spoke to someone who said that flash should take any HTML. Now I am confused as this would point to a dodgy template. Can someone clarify. Do Flash text fields handle all HTML or just a limited subset of HTML. If it is the latter, what happens if it comes across a tag it doesn't recognise? Does it display the tag or break? Thanks, Jason

  • Undocumented Mac Calls

    - by Brian Postow
    I'm working on a couple of mac products, and in order to do what I need to do, I'm using some calls to undocumented methods on Mac Classes. Like IKImageView's doRotate:(id) and PDFDocument's (NSPrintOperation *)getPrintOperationForPrintInfo:(NSPrintInfo *)printInfo autoRotate:(BOOL)doRotate; How common is it for Objective C programmers to use methods like this? How do you find out about them (other than Google)? How dangerous is it to use them? Is there a danger other than that Apple will make them no-longer available in some future rev, and so your program will break?

  • Using string[] as a Dictionary key e.g. Dictionary<string[], StringBuilder>

    - by Nick Allen - Tungle139
    The structure I am trying to achieve is a composite Dictionary key which is item name and item displayname and the Dictionary value being the combination of n strings So I came up with var pages = new Dictionary<string[], StringBuilder>() { { new string[] { "food-and-drink", "Food & Drink" }, new StringBuilder() }, { new string[] { "activities-and-entertainment", "Activities & Entertainment" }, new StringBuilder() } }; foreach (var obj in my collection) { switch (obj.Page) { case "Food": case "Drink": pages["KEY"].Append("obj.PageValue"); break; ... } } The part I am having trouble with is accessing the Dictionary Key pages["KEY"] How do I target the Dictionary Key whose value at [0] == some value? Hope that makes sense

  • Perl references not returning correct values

    - by martincarlin87
    Hi, this is my first time asking a question here so apologies if I am not following any conventions correctly. I encountered a bug in some Perl code that basically lost any parameters in the URL after the first name-value pair and the solution was to use the URI::Escape function on the URL. After this change I decided to move code that does this to a Perl module (Utils.pm) so that any future changes only need to be made once in this file, rather than have to update every file that uses it. The problem I seem to have is that the user, passwd and priv variables don't seem to return the correct values - the system still allows you to sign in but it can't identify your name or the privileges that you have. Below is a link to a pastebin of the code I believe to be relevant to the problem. I believe it is to do with the references but any changes I make just break the page! If anyone has any ideas I would greatly appreciate the help. http://pastebin.com/tqGfGutW

  • bash tips needed for understanding how to escape characters in command-line

    - by Jesper Rønn-Jensen
    My knowledge of commandline bash is missing on a particular area: I constantly forget how to properly escape characters. Today I wanted to echo this string into a file: #!/bin/env bash python -m SimpleHTTPServer echo "#!/bin/env bash\npython -m SimpleHTTPServer" server.sh && chmod +x server.sh -bash: !/bin/env: event not found That's right: Remember to escape ! or bash will think it's a special bash event command. But I can't get the escaping right! \! yields \! in the echoed string, and so does \\!. Furthermore, \n will not translate to a line break. Do you have some general tips that makes it easier for me to understand escaping rules? To be very precise, I'll accept an answer which tells me which characters I should escape on the bash command line? Including how to correctly output newline and exclamation mark in my example.

  • TFS Database Edition doesn't seem to Script Logins

    - by Jaco Pretorius
    I'm trying to put all our databases in TFS. For this purpose we're using TFS Database edition - I've seen some of the other Dev teams use it and it seems pretty good. Problem is that it doesn't seem to script the logins - the users are linked to logins which now break due to the logins not being scripted. As far as I can tell I can't get around this - the Schemas need the users which in turn need the logins. How do you handle logins in TFS Database Projects? This is SQL Server 2008.

  • iPhone: Grouped Table Confusion

    - by senfo
    I'm trying to follow along with this UITableView tutorial and I'm afraid I'm getting confused. What I hope to accomplish is to create a grouped table, which resembles the look and feel of the following image (image source): For each "break" in the table, I assume that I need another section. I understand there is a global NSMutableArray, which acts as the data source to the UITableView. Inside this global array, there are dictionaries for sections and for data, but this is where I start getting confused. Should I create a unique table to store each section in addition to a new table for the rows that are part of that section? In other words, if I have five sections, will I end up with ten unique collections of data (one for each section and one to store the rows related to the section), which all eventually get stored in the global array?

  • Is it naughty to have a large utility file?

    - by banister
    In my C project I have quite a large utils.c file. It is really full of many utilities of different sorts. I feel a bit naughty just stuffing different miscellaneous functions in there. For example it has some utilities related to low level stuff such as a lowercase() function, and it also has some quite sophisticated utilities such as converting to/from different colour formats. My question is, is it very naughty to have such a large utils.c with many different types of utilities in it? Should I break it up into many different kinds of utility files? Such as graphics_utils.c and so on What do you think?

  • ASP.NET: Enumerating header elements from codebehind

    - by JamesBrownIsDead
    On Page_Load() in the codebehind, I'd like to enumerate all the <link> tags. The purpose being I want want to add a <link> to a CSS file if it isn't specified in the Page's markup. How can I do this? I'm thinking I should be able to use LINQ on the collection of elements in the header, no? Here's my pseudocode: var pageAlreadyContainsCssLink = false; foreach(var control in this.Header.Controls) { if (control.TagName == "link" && control.Attributes["href"] == "my_css_file.css") { pageAlreadyContainsCssLink = true; break; } } if (pageAlreadyContainsCssLink) { // Don't add <link> element return; } // Add the <link> to the CSS this.AddCssLink(...);

    Say I have a string like this: 07-MAY-07 Hello World 07-MAY-07 Hello Again So the pattern is, DD-MMM-YY, where MMM is the three letter format for a month. What Regular Expression will break up this string into: 07-MAY-07 Hello World 07-MAY-07 Hello Again Using Jason's code below modified for C#, string input = @"07-MAY-07 Hello World 07-MAY-07 Hello Again"; string pattern = @"(\d{2}-[A-Z]{3}-\d{2}\s)(\D*|\s)"; string[] results = Regex.Split(input, pattern); results.Dump(); Console.WriteLine("Length = {0}", results.Count()); foreach (string split in results) { Console.WriteLine("'{0}'", split); Console.WriteLine(); } I get embedded blank lines? Length = 7 '' '07-MAY-07 ' 'Hello World ' '' '07-MAY-07 ' 'Hello Again' '' I don't even understand why I am getting the blank lines...?

  • How big can a user agent string get?

    - by Josh
    If you were going to store a user agent in a database, how large would you accomdate for? I found this technet article which recommends keeping UA under 200. It doesn't look like this is defined in the HTTP specification at least not that I found. My UA is already 149 characters, and it seems like each version of .net will be adding to it. I know I can parse the string out and break it down but I'd rather not. EDIT Based on this Blog IE9 will be changing to send the short UA string. This is a good change.

  • OpenCL: does it play well with OpenMP, can I connect other languages to it, etc.

    - by Cem Karan
    The 1.0 spec for OpenCL just came out a few days ago (Spec is here) and I've just started to read through it. I want to know if it plays well with other high performance multiprocessing APIs like OpenMP (spec) and I want to know what I should learn. So, here are my basic questions: If I am already using OpenMP, will that break OpenCL or vice-versa? Is OpenCL more powerful than OpenMP? Or are they intended to be complementary? Is there a standard way of connecting an OpenCL program to a standard C99 program (or any other language)? What is it? Does anyone know if anyone is writing an OpenCL book? I'm reading the spec, but I've found books to be more helpful.
