  • JQuery Simplemodal and Tabs Help Needed

    - by Dave R
    Hi, I've got an asp.net page containing a Textbox with an Autocomplete extender on it. It's setup so the user can type a short reference code into the textbox and then choose from the list of matching codes returned by the autocomplete. On the "select", I then call the server using JQuery. I'm currently using $.get here.... The callback function from $.get checks for "success" and then displays a simple-modal dialog containing info about the item they've just selected. if (sStatus == "success") { $.modal(sText, { overlayClose: true, appendTo:'form', onShow: function(dialog) { $("#ccTargets_tabContainer").tabs(); }, onClose: function(dialog) { $("#<%=TextBox1.ClientID%>").val(""); $.modal.close(); } }); $.ready(); } One of the bits of info being loaded here is a JQuery TABS setup, so the onShow function of the simplemodal is used to initiate the tabs which are within the simplemodal. Now to the crux of my problem. If I do multiple consecutive "autocompletes" on the same page it all works fine Unless I have selected a different tab on the tabs in the simplemodal ....If I select a different tab, close the simplemodal and then do another autocomplete I get a JQuery error which seems to relate to a selector doing something with the "old" selected tab that was on the "closed" modal. I'm clearly missing some sort of cleardown / initialisation somewhere, but can't find what it is. Help? I've tried "tabs.destroy" before the modal call in the code above and I've tried a $.ready() call as indicated too.... UPDATE: Is it something to do with JQuery Tabs appending my addressbar URL with the selected tab's ID?

  • Which combing css technique?

    - by DotnetShadow
    Hi there, Which of the following would you say is the best way to go when combining files for CSS: Say I have a master.css file that is used across all pages on my website (page1.aspx, page2.aspx) Page1.aspx - A specific page that has some unique css that is only ever used on that page, so I create a page1.css and it also uses another css grids.css Page2.aspx - Another specific page that is different from all other pages on the site and is different to page1.aspx, I'll name this page2.aspx and make a page2.css this doesn't use grids.css So would you combine the scripts as: Option1: Combine scripts csshandler.axd?d=master.css,page1.css,grids.css when visiting page1 Combine scripts csshandler.axd?d=master.css,page2.css when visiting page2 Benefits: Page specific, rendering quicker since only selectors for that page need to be matched up no unused selectors Drawback: Multiple combinations of master.css + page specific hence master.css has to be downloaded for each page Option2: Combine all scripts whether a page needs them or not csshandler.axd?d=master.css,page1.css,page2.css,grids.css (master, page1 and page2) that way it gets cached as one. The problem is that rendering maybe slower since it will have to try and match EVERY selector in the css with selectors on the page even the missing ones, so in the case of page2.aspx that doesn't use grids.css the selectors in grids.css will need to be parsed to see if they are in page2 which means rendering will be slow Benefits: One file will ever be downloaded and cached doesn't matter what page you visit Drawback: Unused selectors will need to be parsed by the browser slower rendering Option3: Leave the master file on it's own and only combine other scripts (the benefit of this is because master is used across all pages there is a chance that this is cached so doesn't need to keep on downloading csshandler.axd?d=Master.css csshandler.axd?d=page1.css,grids.css Benefits: master.css file can be cached doesn't matter what page you visit. Not many unused selectors as page spefic is applied Drawback: Initially minimum of 2 HTTP request will have to be made What do you guys think? Cheers DotnetShadow

  • CSS - Inheriting layered background images

    - by NNN
    CSS3 supports multiple background images, for example: foo { background-image: url(/i/image1.jpg), url(/i/image2.jpg); } I'd like to be able to add a secondary image to an element with a class though. So for example, say you have a nav menu. And each item has a background image. When a nav item is selected you want to layer on another background image. I do not see a way to 'add' a background image instead of redeclaring the whole background property. This is a pain because in order to do this with multi-backgrounds, you would have to write the base bg image over and over for each item if the items have unique images. Ideally I'd be able to do something like this: li { background: url(baseImage.jpg); } li.selected { background: url(selectedIndicator.jpg); } And have li.selected's end result appear the same if I did: li.selected { background: url(baseImage.jpg), url(selectedIndicator.jpg); } Update: I also tried the following with no luck (I believe backgrounds are not inherited..) li { background: url(baseImage.jpg), none; } li.selected { background: inherit, url(selectedIndicator.jpg); }

  • CakePHP 1.3 and Uploadifive/Uploadify - Change Upload Filename to a random string

    - by CaboONE
    I have somehow implemented UPLOADIFIVE in my CakePHP application. Everything seems to work great including uploading multiple files and inserting the correct information in the Database. Based on the following code, I would like to UPLOAD AND SAVE EVERY FILE WITH A RANDOM NAME TAKING INTO ACCOUNT THE CURRENT DATE OR SOMETHING SIMILAR. How could I accomplish this? In my Photos Controller I have the following function: // This function is called at every file upload. It uploads the file onto the server // and save the corresponding image name, etc, to the database table `photos`. function upload() { $uploadDir = '/img/uploads/photos/'; if (!empty($_FILES)) { debug($_FILES); $tempFile = $_FILES['Filedata']['tmp_name'][0]; $uploadDir = $_SERVER['DOCUMENT_ROOT'] . $uploadDir; $targetFile = $uploadDir . $_FILES['Filedata']['name'][0]; // Validate the file type $fileTypes = array('jpg', 'jpeg', 'gif', 'png'); // Allowed file extensions $fileParts = pathinfo($_FILES['Filedata']['name'][0]); // Validate the filetype if (in_array($fileParts['extension'], $fileTypes)) { // Save the file move_uploaded_file($tempFile,$targetFile); $_POST['image'] = $_FILES['Filedata']['name'][0]; $this->Photo->create(); if ($this->Photo->save($_POST)) { $this->Session->setFlash($targetFile, 'default', array('class' => 'alert_success')); $this->redirect(array('action' => 'index')); } } else { // The file type wasn't allowed //echo 'Invalid file type.'; $this->Session->setFlash(__('The photo could not be saved. Please, try again.', true)); } } } In my View file - admin_add.ctp I have added the following function $('#file_upload').uploadifive({ 'auto' : false, 'uploadScript' : '/photos/upload', 'buttonText' : 'BROWSE FILES', 'method' : 'post', 'onAddQueueItem' : function(file) { this.data('uploadifive').settings.formData = { 'photocategory_id' : $('#PhotoPhotocategoryId').val() }; } }); <input type="file" name="file_upload" id="file_upload" />

  • Python beginner having trouble running code

    - by Protean
    For some reason this code will not seem to run in the interpreter. When I hit F5 nothing happens, not even the debugger seems to recognize it. I assume it has something to do with the class, as when removed the interpreter seems to recognize the rest of the code. Please tell me what I am doing wrong. Edit: I have restarted the interpreter multiple times, any other piece of code I try to load runs fine, just this one is having trouble. print ('Why won't this work?') class sorting_class: def __init__(self): self.order = ['a', 'b', 'c', 'd'] self.globali = 0 self.orderi = 0 self.sortedlist = [] def sort(self, array): carry, leave = [] for arrayi in array: print ('run', arrayi) if self.order[self.orderi] == arrayi[self.globali]: carry.append(arrayi) else: if self.globali != 0: leave.append(arrayi) return carry, leave def srt(self, array): globalii = 0 carry, leave = my.sort(array) while len(self.sortedlist) != len(array): if len(self.carry) == 1: self.sortedlist.append(carry) arrayt = leave self.globali = 1 self.orderi = 0 carry, leave = my.sort(arrayt) elif len(self.carry) == 0: if len(self.leave) != 0: arrayt = leave self.globali = 1 self.orderi += 1 my.sort(arrayt) else: self.arrayt globalii += 1 self.orderi = globalii self.globali = 0 my.sort(arrayt) self.orderi = 0 else: arrayt = carry carry = [] self.globali += 1 carry, leave += my.sort(arrayt) my = sorting_class() x = ['ac', 'bc' ,'ab', 'da'] my.srt(x)

  • LaTeX: bibliography per chapter.

    - by YuppieNetworking
    Hello all, I am helping a colleague with his PhD thesis and we need to present the bibliography at the end of each chapter. The question is: does anyone have a minimal working example for this case using latex+bibtex? The current document structure that we use is the following: main.tex chap1.tex chap2.tex ... chapn.tex biblio.bib Where main.tex contains packages, document declarations, macros and \includes for each chapter. biblio.bib is the only bibtex file (I think is easier to have all citations in one place). We have searched and tried with different latex packages, reading and following their documentation. Specifically, bibitems and chapterbib. bibitems successfully generates bu*.aux files, but when running bibtex for each one of them, an error occurs since there is no \bibdata element in the .aux file. chapterbib also generates a .aux file, but bibtex finishes with an error caused by using multiple \bibliography{file} in the .tex files (one per chapter). Some coworkers suggested using a separate bibtex file for each chapter, which could be a problem of maintenance in the future when citing the same publications in different chapters. We will like to continue having this document structure, if possible. So, if anyone could shed some light to this problem, we will appreciate it. Thanks.

  • Take screenshot with Selenium: WaitForPageToLoad does not wait long enough

    - by OregonGhost
    I'm trying to get screenshots from a web page with multiple browsers. Just experimenting with Selenium RC, I wrote code like this: var sel = new DefaultSelenium(server, 4444, target, url); sel.Start(); sel.Open(url); sel.WaitForPageToLoad("30000"); var imageString = sel.CaptureScreenshotToString(); This basically works, but in most cases the screenshot is of a blank browser window, because the page is not yet ready for display. It kind of works if I add a sleep just after the WaitForPageToLoad, but that slows down the fast browsers and/or may be to short for the slower browsers (or under load). A typical solution for this seems to be to wait for the presence of a certain element. However, this is meant as a simple generic solution to get a screenshot of a local web page with as many browsers as possible (to test the layout) and I don't want to have to enter certain element names or whatever. It's a simple tool where you just enter the Selenium Server URL and the URL you want to test, and get the screenshots back. Any advice?

  • Using hibernate criteria, is there a way to escape special characters?

    - by Kevin Crowell
    For this question, we want to avoid having to write a special query since the query would have to be different across multiple databases. Using only hibernate criteria, we want to be able to escape special characters. This situation is the reason for needing the ability to escape special characters: Assume that we have table 'foo' in the database. Table 'foo' contains only 1 field, called 'name'. The 'name' field can contain characters that may be considered special in a database. Two examples of such a name are 'name_1' and 'name%1'. Both the '_' and '%' are special characters, at least in Oracle. If a user wants to search for one of these examples after they are entered in the database, problems may occur. criterion = Restrictions.ilike("name", searchValue, MatchMode.ANYWHERE); return findByCriteria(null, criterion); In this code, 'searchValue' is the value that the user has given the application to use for its search. If the user wants to search for '%', the user is going to be returned with every 'foo' entry in the database. This is because the '%' character represents the "any number of characters" wildcard for string matching and the SQL code that hibernate produces will look like: select * from foo where name like '%' Is there a way to tell hibernate to escape certain characters, or to create a workaround that is not database type sepecific?

  • cleaning up noise in an edge detection algoritum

    - by Faken
    I recently wrote an extremely basic edge detection algorithm that works on an array of chars. The program was meant to detect the edges of blobs of a single particular value on the array and worked by simply looking left, right, up and down on the array element and checking if one of those values is not the same as the value it was currently looking at. The goal was not to produce a mathematical line but rather a set of ordered points that represented a descritized closed loop edge. The algorithm works perfectly fine, except that my data contained a bit of noise hence would randomly produce edges where there should be no edges. This in turn wreaked havoc on some of my other programs down the line. There is two types of noise that the data contains. The first type is fairly sparse and somewhat random. The second type is a semi continuous straight line on the x=y axis. I know the source of the first type of noise, its a feature of the data and there is nothing i can do about it. As for the second type, i know it's my program's fault for causing it...though i haven't a hot clue exactly what is causing it. My question is: How should I go about removing the noise completely? I know that the correct data has points that are always beside each other and is very compact and ordered (with no gaps) and is a closed loop or multiple loops. The first type of noise is usually sparse and random, that could be easily taken care of by checking if any edges is next that noise point is also counted as an edge. If not, then the point is most defiantly noise and should be removed. However, the second type of noise, where we have a semi continuous line about x=y poses more of a problem. The line is sometimes continuous for random lengths (the longest was it went half way across my entire array unbroken). It is even possible for it to intersect the actual edge. Any ideas on how to do this?

  • ASP.NET Ajax - Asynch request has separate session???

    - by Marcus King
    We are writing a search application that saves the search criteria to session state and executes the search inside of an asp.net updatepanel. Sometimes when we execute multiple searches successively the 2nd or 3rd search will sometimes return results from the first set of search criteria. Example: our first search we do a look up on "John Smith" - John Smith results are displayed. The second search we do a look up on "Bob Jones" - John Smith results are displayed. We save all of the search criteria in session state as I said, and read it from session state inside of the ajax request to format the DB query. When we put break points in VS everything behaves as normal, but without them we get the original search criteria and results. My guess is because they are saved in session, that the ajax request somehow gets its own session and saves the criteria to that, and then retrieves the criteria from that session every time, but the non-async stuff is able to see when the criteria is modified and saves the changes to state accordingly, but because they are from two different sessions there is a disparity in what is saved and read. EDIT::: To elaborate more, there was a suggestion of appending the search criteria to the query string which normally is good practice and I agree thats how it should be but following our requirements I don't see it as being viable. They want it so the user fills out the input controls hits search and there is no page reload, the only thing they see is a progress indicator on the page, and they still have the ability to navigate and use other features on the current page. If I were to add criteria to the query string I would have to do another request causing the whole page to load, which depending on the search criteria can take a really long time. This is why we are using an ajax call to perform the search and why we aren't causing another full page request..... I hope this clarifies the situation.

  • WinForms Application Form "Shakes" When Audio Playing

    - by ikurtz
    I have a C# game program that i'm developing. it uses sound samples and winsock. when i test run the game most of the audio works fine but from time to time if it is multiple samples being played sequentially the application form shakes a little bit and then goes back to its old position. how do i go about debugging this or present it to you folks in a manageable manner? i'm sure no one is going to want the whole app code in fear of virus attacks. please guide me.. EDIT: i have not been able to pin down any code section that produces this result. it just does and i cannot explain it. EDIT: no the x/y position are not changing. the window like shakes around a few pixels and then goes back to the position were it was before the shake. if (audio) { Stream stream; SoundPlayer player; stream = Properties.Resources.ResourceManager.GetStream("_home"); player = new System.Media.SoundPlayer(stream); player.PlaySync(); player.Dispose(); string ShipID = fireResult.DestroyedShipType.ToString(); stream = Properties.Resources.ResourceManager.GetStream("_" + ShipID); player = new System.Media.SoundPlayer(stream); player.PlaySync(); player.Dispose(); stream = Properties.Resources.ResourceManager.GetStream("_destroyed"); player = new System.Media.SoundPlayer(stream); player.PlaySync(); player.Dispose(); } can you see anything in the above code that would produce this shake?

  • Perl strings internals

    - by n0rd
    How does perl strings represented internally? What encoding is used? How do I handle different encodings properly? I've been using perl for quite a long time, but it didn't include a lot of string handling in different encodings, and when I encountered a minor problem that had something to do with encodings I usually resorted to some shamanic actions. Until this moment I thought about perl strings as sequences of bytes, which did fit pretty well for my tasks. Now I need to do some processing of UTF-8 encoded file and here starts trouble. First, I read file into string like this: open(my $in, '<', $ARGV[0]) or die "cannot open file $ARGV[0] for reading"; binmode($in, ':utf8'); my $contents; { local $/; $contents = <$in>; } close($in); then simply print it: print $contents; And I get two things: a warning Wide character in print at <scriptname> line <n> and a garbage in console. So I can conclude that perl strings have a concept of "character" that can be "wide" or not, but when printed these "wide" characters are represented in console as multiple bytes, not as single "character". (I wonder now why did all my previous experience with binary files worked quite how I expected it to work without any "character" issues). Why then I see garbage in console? If perl stores strings as character in some known encoding, I don't think there is a big problem to find out console encoding and print text properly. (I use Windows, BTW). If perl stores strings as multibyte sequences (e.g. using same UTF-8 encoding), why is it done this way? From my C experience handling multibyte strings is PAIN.

  • C++ help with getline function with ifstream

    - by John
    So I am writing a program that deals with reading in and writing out to a file. I use the getline() function because some of the lines in the text file may contain multiple elements. I've never had a problem with getline until now. Here's what I got. The text file looks like this: John Smith // Client name 1234 Hollow Lane, Chicago, IL // Address 123-45-6789 // SSN Walmart // Employer 58000 // Income 2 // Number of accounts the client has 1111 // Account Number 2222 // Account Number ifstream inFile("ClientInfo.txt"); if(inFile.fail()) { cout << "Problem opening file."; } else { string name, address, ssn, employer; double income; int numOfAccount; getline(inFile, name); getline(inFile, address); // I'll stop here because I know this is where it fails. When I debugged this code, I found that name == "John", instead of name == "John Smith", and Address == "Smith" and so on. Am I doing something wrong. Any help would be much appreciated.

  • Eclipse randomly exits after installation of Blackberry plugin/SDK

    - by canadiancreed
    Hello all Since adding the Blackberry Java classes from their website into eclipse, I've had it where eclipse will randomly close, with no discernible pattern, rhyme, error or reason. Here is the environment/software packages that I am using: Windows XP SP2 Eclipse v3.5.1 Blackberry Java Plugin v1.1.1.200911111641-15 Blackberry Java SDK 4.5.0.21 I've tried the usual steps of complete uninstall and reinstallation of Eclipse and the accompanying plugins on multiple systems with the same configuration, including one that had a fresh install of Windows XP SP2. Upgrading to Eclipse 3.6 didn't work (the plugin wont' install as it's the wrong version), nor the downgrade to 3.4 for the same reason. I also increased the heap size to 512 (system has two gigs of memory) as some research into Eclipse doing this type of thing with Groovy was resolved that way, but again, no dice. Eclipse works great when the blackberry plugins are not installed, and no entries of errors or issues in the event log are helping to show what the issue with these plug-ins might be. So if anyone has ran into this issue, and even better, has a solution, I'd love to hear about it. Thanks in advance. EDIT: An additional to my issue, autoComplete with the Blackberry SDK seems to make this extremely unstable, like almost a guaranteed crash. Is this fixable at all?

  • Asynchronously populate datagridview in Windows Forms application

    - by dcryptd
    howzit! I'm a web developer that has been recently requested to develop a Windows forms application, so please bear with me (or dont laugh!) if my question is a bit elementary. After many sessions with my client, we eventually decided on an interface that contains a tabcontrol with 5 tabs. Each tab has a datagridview that may eventually hold up to 25,000 rows of data (with about 6 columns each). I have successfully managed to bind the grids when the tab page is loaded and it works fine for a few records, but the UI freezes when I bound the grid with 20,000 dummy records. The "freeze" occurs when I click on the tab itself, and the UI only frees up (and the tab page is rendered) once the bind is complete. I communicated this to the client and mentioned the option of paging for each grid, but she is adament w.r.t. NOT wanting this. My only option then is to look for some asynchronous method of doing this in the background. I don't know much about threading in windows forms, but I know that I can use the BackgroundWorker control to achieve this. My only issue after reading up a bit on it is that it is ideally used for "long-running" tasks and I/O operations. My questions: How does one determine a long-running task? How does one NOT MISUSE the BackgroundWorker control, ie. is there a general guideline to follow when using this? (I understand that opening/spawning multiple threads may be undesirable in certain instances) Most importantly: How can I achieve (asychronously) binding of the datagridview after the tab page - and all its child controls - loads. Thank you for reading this (ahem) lengthy query, and I highly appreciate any responses/thoughts/directions on this matter! Cheers!

  • Doctrine stupid or me stupid?

    I want to use a single Doctrine install on our server and serve multiple websites. Naturally the models should be maintained in the websites' modelsfolder. I have everything up (and not running) like so: Doctrine @ /CustomFramework/Doctrine Websites @ /var/www/vhosts/custom1.com/ /var/www/vhosts/custom2.com/ Generating works fine, all models are delivered in /application_folder/models and /application_folder/models/generated for the correct website. I've added Doctrine::loadModels('path_to_models') in the bootstrap file for each website, and also registered the autoloaded. But.... This is the autoloader code: public static function autoload($className) { if (strpos($className, 'sfYaml') === 0) { require dirname(__FILE__) . '/Parser/sfYaml/' . $className . '.php'; return true; } if (0 !== stripos($className, 'Doctrine_') || class_exists($className, false) || interface_exists($className, false)) { return false; } $class = self::getPath() . DIRECTORY_SEPARATOR . str_replace('_', DIRECTORY_SEPARATOR, $className) . '.php'; if (file_exists($class)) { require $class; return true; } return false; } Am I stupid, or is the autoloader really doing this: $class = self::getPath() . DIRECTORY_SEPARATOR . str_replace('_', DIRECTORY_SEPARATOR, $className) . '.php'; or, in other words: Does it require me to have ALL my generated doctrine classes inside the Doctrine app directory? Or in other words, do I need a single Doctrine installation for each website? I'm getting an error that the BaseXXX class cannot be found. So the autoloading doesn't function correctly. I really hope i'm doing something wrong.. anyone?

  • How to express inter project dependencies in Eclipse PDE

    - by Roland Tepp
    I am looking for the best practice of handling inter project dependencies between mixed project types where some of the projects are eclipse plug-in/OSGI bundle projects (an RCP application) and others are just plain old java projects (web services modules). Few of the eclipse plug-ins have dependencies on Java projects. My problem is that at least as far as I've looked, there is no way of cleanly expressing such a dependency in Eclipse PDE environment. I can have plug-in projects depend on other plug-in projects (via Import-Package or Require-Bundle manifest headers), but not of the plain java projects. I seem to be able to have project declare a dependency on a jar from another project in a workspace, but these jar files do not get picked up by neither export nor launch configuration (although, java code editing sees the libraries just fine). The "Java projects" are used for building services to be deployed on an J2EE container (JBoss 4.2.2 for the moment) and produce in some cases multiple jar's - one for deploying to the JBoss ear and another for use by client code (an RCP application). The way we've "solved" this problem for now is that we have 2 more external tools launcher configurations - one for building all the jar's and another for copying these jar's to the plug-in projects. This works (sort of), but the "whole build" and "copy jars" targets incur quite a large build step, bypassing the whole eclipse incremental build feature and by copying the jars instead of just referencing the projects I am decoupling the dependency information and requesting quite a massive workspace refresh that eats up the development time like it was candy. What I would like to have is a much more "natural" workspace setup that would manage dependencies between projects and request incremental rebuilds only as they are needed, be able to use client code from service libraries in an RCP application plug-ins and be able to launch the RCP application with all the necessary classes where they are needed. So can I have my cake and eat it too ;) NOTE To be clear, this is not so much about dependency management and module management at the moment as it is about Eclipse PDE configuration. I am well aware of products like [Maven], [Ivy] and [Buckminster] and they solve a quite different problem (once I've solved the workspace configuration issue, these products can actually come in handy for materializing the workspace and building the product)

  • Loops on a Matlab program

    - by lebland-matlab
    I have 3 sets of 10 vectors each, and I want to take 2 vectors from the first set , 2 vectors from the second set and 3 vectors from the third set . My goal is to make a loop to implement the following program, knowing that after each calculation, the result shall be saved in a new file. My problem is that I can not handle the indices included in the strings. I try to use multiple loops to scan the 3 sets in the order of indices. loops should contain the following program clc; clear all; load('C:\Users\Documents\MATLAB\myFile\matrice_F.mat'); load('C:\Users\Documents\MATLAB\myFile\matrice_G.mat'); F = m_F; G = m_G; load('C:\Users\Documents\MATLAB\myFile\matrice_J.mat'); load('C:\Users\Documents\MATLAB\myFile\matrice_K.mat'); J = m_J; K = m_K; load('C:\Users\Documents\MATLAB\myFile\matrice_N.mat'); load('C:\Users\Documents\MATLAB\myFile\matrice_O.mat'); load('C:\Users\Documents\MATLAB\myFile\matrice_P.mat'); N = m_N ; O = m_O; P = m_P; [A,B,C,D,E] = myFun(F,G,J,K,N,O,P); file_name = 'matrice_final.mat'; save(file_name,'A','B','C','D','E');

  • iOS iPad UIActionSheet Issue

    - by hart1994
    I am currently developing an application which needs an option to 'share' using multiple services; such as email, twitter. To to this, I have a UIBarButtonItem coded in and when touched, it triggers this: UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; [sheet addButtonWithTitle:@"Email"]; [sheet addButtonWithTitle:@"Tweet"]; [sheet addButtonWithTitle:@"Cancel"]; sheet.cancelButtonIndex = sheet.numberOfButtons-1; [sheet showFromRect:self.view.bounds inView:self.view animated:YES]; [sheet release]; In conjunction with this to detect which button is selected: clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex == actionSheet.cancelButtonIndex) { return; } switch (buttonIndex) { case 0: { [self emailThis]; break; } case 1: { [self tweetThis]; break; } } This works a treat on the iPhone. But unfortunately it displays incorrectly on the iPad. It looks like it is trying to display the UIPopoverController, but it is positioned center of the navbar with practically no height. I have looked into using the UIPopoverController, but I cannot seem to find out how to use it with buttons. Is there anyway I can adapt the code above to properly display the buttons, as it's trying to already. Many thanks, Ryan PS: I'm new to objective-c/iOS coding, so please be specific. Thank you :)

  • ASP.NET MVC Ajax.BeginForm eats params of submit button clicked. Looks like bug.

    - by RonnBlack
    If you are using Ajax.BeginForm() with multiple submit buttons similar to this: // View.aspx <% using (Ajax.BeginForm("Action", "Controller", new AjaxOptions { UpdateTargetId = "MyControl", })) { %> <span id="MyControl"> <% Html.RenderPartial("MyControl"); %> </span> <% } %> //MyControl.ascx <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <input name="prev" type="submit" value="prev" /> <input name="next" type="submit" value="next" /> //... Everything is submitted to the controller fine but the params for the submit button that was clicked are absent from the Request. In otherwords Request["next"] and Request["prev"] are always null. I looked in to the JavaScript in Microsoft.MvcAjax.js and it looks like the function Sys_Mvc_MvcHelpers$_serializeForm completely skips over the inputs that are of type 'submit'. This doesn't seem logical at all. How else can you find out what button has been clicked? It looks like a bug to me. Is there any logical reason to skip these form parameters?

  • Class Structure w/ LINQ, Partial Classes, and Abstract Classes

    - by Jason
    I am following the Nerd Dinner tutorial as I'm learning ASP.NET MVC, and I am currently on Step 3: Building the Model. One part of this section discusses how to integrate validation and business rule logic with the model classes. All this makes perfect sense. However, in the case of this source code, the author only validates one class: Dinner. What I am wondering is, say I have multiple classes that need validation (Dinner, Guest, etc). It doesn't seem smart to me to repeatedly write these two methods in the partial class: public bool IsValid { get { return (GetRuleViolations().Count() == 0); } } partial void OnValidate(ChangeAction action) { if (!IsValid) { throw new ApplicationException("Rule violations prevent saving."); } } What I'm wondering is, can you create an abstract class (because "GetRuleViolations" needs to be implemented separately) and extend a partial class? I'm thinking something like this (based on his example): public partial class Dinner : Validation { public IEnumerable<RuleViolation> GetRuleViolations() { yield break; } } This doesn't "feel" right, but I wanted to check with SO to get opinions of individuals smarter than me on this. I also tested it out, and it seems that the partial keyword on the OnValidate method is causing problems (understandably so). This doesn't seem possible to fix (but I could very well be wrong). Thanks!
