  • selecting a row by means of a button ... using didSelectRowAtIndexPath

    - by John Smith
    hey people , I have a question concerning a button I would like to create which selects my previous selected row. This is what I came up so far but since I'm new with the functionality and such I could definately use some pointers I created a toolbar with a button and behind this button is the following action. -(void)clickRow { selectedRow = [self.tableView indexPathForSelectedRow]; [self.tableView:[self tableView] didSelectRowAtIndexPath:selectedRow]; } in my didSelectRowAtIndexPath there is a rootViewController being pushed rvController = [RootViewController alloc] ...etc So what I would like is my function clickRow to select the row and push the new rootviewcontroller (which has the right info since I'm using a tree ). I tried something like this as well -(void)clickRow { NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; NSArray *Children = [dictionary objectForKey:@"Children"]; rvController = [[RootViewController alloc] initWithNibName:@"RootViewController" bundle:[NSBundle mainBundle]]; rvController.CurrentLevel += 1; rvController.CurrentTitle = [dictionary objectForKey:@"Title"]; [self.navigationController pushViewController:rvController animated:YES]; rvController.tableDataSource = Children; [rvController release]; } The last function works a little but a little is not enough;) For instance if I press the middle row or any other it constantly selects the toprow. thnx all for those of you reading and trying to help

  • why MVC instead of good old asp.net? Still not grasping why I should go this route??

    - by RJ
    I know this question has been asked before and I read all the answers but they still don't give me the answers I am looking for. I need something concrete. I volunteered to give a presentation on MVC to other developers in our group which forces me to learn it. The big question everyone has is: "What can MVC bring to the table that we can't do in asp.net or MVC can do faster. I have just gone through Nerd Dinner and actually created a complete website that sort of mimics Nerd Dinner. But as great a job that Scott Guthrie did on it, there are big gaps that aren't answered such as, how do I throw a textbox on the listing page with a button and do a simple search. In asp.net, I would throw a textbox, button and grid on the page and bind it to a sproc and away I go. What is the equivalent in MVC. I guess I need a really good tutorial on how to use MVC without using Linq-to-Sql. I know I am sort of babbling on about this but it is a very serious question that still seems to go unanswered. On a side note, the View page of MVC brings back nightmares of classic asp with all the in-line code that we got away from way back when with code behind pages. Yes, MVC has Controller and Model classes which are great but I still don't like the classic asp tags in the html. Help me out here, I really like the concept of MVC and want it to be successful but I need more!

  • What is the PastryKit Framework?

    - by Kerrick
    I'm trying to find any information I can on the PastryKit Javascript Framework. It appears to be in use on the iPhone User Guide that is displayed on the iPhone itself in Mobile Safari, but I cannot find any documentation or API. If you want to see it in action, open Safari 4, set your user agent to iPhone 3 (In the Develop menu) and check out the guide. Overall, it seems to be a way to write an HTML/CSS/Javascript application that acts like a native iPhone app. When it comes to Javascript, I used the JS Beautifier on (what I assume to be) the framework file and it was over 3,400 lines! Beautified, (again what I assume to be) their implementation of it was over 1,200 lines. On the CSS side, I used Clean CSS on (again what I assume to be) the framework CSS, and it came out to over 700 lines. Their implementation was shy of 500. Does anybody have, or know where to find, any information, documentation, or APIs on PastryKit? Or, can anybody figure out how to implement it?

  • Is there a way to validates_presence_of only one time? (to skip that validation once the user's been

    - by GoodGets
    So, I'd like for a user to see an error message if he submits a comment and the :name is blank (typical error message, don't need help with that). However, I'd then like to allow the user to skip that validation once he's been notified that "we like all comments to have a name." So, he submits the comment once, sees the notification, then can submit the form again unchanged if he really doesn't want to add a name, and the validates_presences_of :name is skipped. But, I'm not sure how to go about doing this. I thought about checking to see where the request is coming from, but after a create, errors are handed off to the "new" action, which is the same as actual "new" comments. I then thought about checking to see if flash[errors] were present, but that won't work because there are other validations a comment has to pass. Finally, I thought about trying a validates_presences_of :name, :unless = :notified but wasn't sure how to define notified. I honestly hate asking such an open ended question, but wasn't sure where to get started. So, is there a way to just check a certain validation once?

  • Suggest the way to design several classes

    - by Oleg Tarasenko
    Hi, I'm building simple application on as3. Kind of starship game. What I want to do is to create several different star ships. Each one should have different images (different look), different sets of animation (e.g. when it's flying, burning, damaged), different kind of weapon and also different controllers (e.g. one can be managed by user, another one by computer, and I want to be able to reuse same ships for AI controller as well as for users controls). Each ship is created in the following way: Create entity Add spatial Add renderers Add other components.... ...... n. init the ship So what I am trying to do: 1) Create StarShip superclass, to store HP (as every ship has it), store spatial (same reason) 2) Create inherited class for any other ship... (It will contain renderer - (responsible for display part), weapon, set of animations), etc What do you think about such way of composition? Maybe it's better to place everything in super class, and then just create instances using long, long, long constructors like: StarShip(hp:HP, animations:DICT, weapon:Weapon, ....) Need advice

  • Android "first time" app user tutorial

    - by EGHDK
    I'm trying to create an opening tutorial that consists of four panes for my application, but since I'm new to Android, I want to make sure I'm considering all of my options before marking this task as "complete". I know of three ways, I can only really accomplish one. There are no requirements for this tutorial, but some "wanted features" would be a sliding action to each pane would be nice as well as the image and the bottom (navigation circles) not moving and the title on top not moving. One Way 4 separate activities and 4 separate layouts The red circled items are textViews that are centered horizontally and pushed off the top. The white circled items are imageViews that are centered horizontally and vertically. The purple circled are imageViews that are centered horizontally and pushed off the bottom. Second Way 4 fragments on one activity Fragments were difficult to learn, but the more I read about them/see tutorials on them, they seem to only really be used for tablets. Would it be a valid way to accomplish this? Third Way ViewPager? http://android-developers.blogspot.com/2011/08/horizontal-view-swiping-with-viewpager.html I've never used this before, but I know it's an option. Final Question Which way is used more often/what's the proper way to implement this? Is there any way to only have the middle part (the image) slide in, but the title (top) and the navigation images (bottom) just change once the image slides in?

  • JSF - Creating an overlay for popup panels.

    - by Ben
    Hi, I've created an overlay that will popup whenever someone wants to upload a file to the system. The Gui looks like this (when the overlay is up) I have two problems with this: I attached a a4j:support object that, onclick, makes the overlay disappear. The problem with this is that when I click the upload button on the upload component, support catches the click event and closes the overlay with the upload component before I have the chance to finish the operation. I chose two different style classes. One for the overlay and one for the upload panel. But the styling of the overlay takes over the upload component and it becomes transparent as well. The implementation looks something like this: <h:panelgroup layout="block" styleClass="overlayClass"> <rich:fileUpload styleClass="uploadStyleClass"... /> <a4j:support event="onclick" action="#{mrBean.switchOverlayState}" reRender="..."/> </h:panelGroup> The CSS: .overlayClass { Opacity: 0.5; position: fixed; left: 0; right: 0; top: 0; bottom: 0; background: #000; } .uploadStyleClass { opacity: 1.0; ... } Thanks for the help!

  • How to display a generic error page in Asp.Net MVC 2

    I have the following in my base controller: protected override void OnException(ExceptionContext filterContext) { if (filterContext == null) { throw new ArgumentNullException("filterContext"); } // If custom errors are disabled, we need to let the normal ASP.NET exception handler // execute so that the user can see useful debugging information. if (filterContext.ExceptionHandled || !filterContext.HttpContext.IsCustomErrorEnabled) { return; } Exception exception = filterContext.Exception; // If this is not an HTTP 500 (for example, if somebody throws an HTTP 404 from an action method), // ignore it. if (new HttpException(null, exception).GetHttpCode() != 500) { return; } // TODO: What is the namespace for ExceptionType? //if (!ExceptionType.IsInstanceOfType(exception)) //{ // return; //} // Send Email MailException(exception); // TODO: What does this line do? base.OnException(filterContext); filterContext.Result = new ViewResult { ViewName = "Error" }; filterContext.ExceptionHandled = true; filterContext.HttpContext.Response.Clear(); filterContext.HttpContext.Response.StatusCode = 500; } In my Shared folder, I have an Error.aspx View. Web.config <customErrors mode="On" /> I am still seeing the yellow screen when an exception occurs. What am I doing incorrectly?

  • Chrome not sending POST requests on localhost, Firefox works fine

    - by AP257
    I have copied the simple Django forms example exactly, running on localhost. The basic contact form example should submit a POST request when you click the Submit button. I'm running Chrome on Mac Snow Leopard, and whenever I submit the form, the page simply reloads with an empty form: I can see from the runserver output that it's not sending a POST - instead it's sending a GET request. If I open the same page in Firefox on Mac Snow Leopard, and submit the form, I can see it's sending a POST request (as it should be). Looking at the source in Chrome, the form definitely says method="post". <form action="/contact/" method="post"> <p><label for="id_subject">Subject:</label> <input id="id_subject" type="text" name="subject" maxlength="100" /></p> <p><label for="id_message">Message:</label> <input type="text" name="message" id="id_message" /></p> <p><label for="id_sender">Sender:</label> <input type="text" name="sender" id="id_sender" /></p> <p><label for="id_cc_myself">Cc myself:</label> <input type="checkbox" name="cc_myself" id="id_cc_myself" /></p> <input type="submit" value="Submit" /> </form> External sites with POST forms seem to work OK in Chrome. In addition, if I fill the form in incorrectly, in Chrome the page just reloads, with a GET request, as before; in Firefox the form gets validated, as it should. I've tried with other POST forms on localhost and got the same result. I know Chrome for Mac has its quirks, but what on earth is going on?

  • Validating Age field javascript beginner

    - by Marcelo
    Hi people, I'm trying to validate an age field in a form but I'm having some problem. First I tried to make sure that the field will not be send empty. I don't know javascript so I searched some scripts and adapted them to this: function isInteger (s) { var i; if (isEmpty(s)) if (isInteger.arguments.length == 1) return 0; else return (isInteger.arguments[1] == true); for (i = 0; i < s.length; i++) { var c = s.charAt(i); if (!isDigit(c)) return false; } return true; } function isEmpty(s) { return ((s == null) || (s.length == 0)) } function validate_required(field,alerttxt) { with (field) { if (value==null||value=="") { alert(alerttxt);return false; } else { return true; } } } function validate_form(thisform) { with (thisform) { if ((validate_required(age,"Age must be filled out!")==false) || isInteger(age,"Age must be and int number")==false)) {email.focus();return false;} } } //html part <form action="doador.php" onsubmit="return validate_form(this)" method="post"> It's working fine for empty fields, but if I type any letters or characters in age field, it'll be sent and saved a 0 in my database. Can any one help me ? Sorry for any mistake in English, and thanks in andvance for your help.

  • Validating Time & Date To Be At Least A Certain Amount Of Time In The Future

    - by MJH
    I've built a reservation form for a taxi company which works fine, but I'm having an issue with users making reservations that are due too soon in the future. Since the entire form is kind of long, I first want to make sure the user is not trying to make a reservation for less than an hour ahead of time, without them having to fill out the whole form. This is what I have come up with so far, but it's just not working: <?php //Set local time zone. date_default_timezone_set('America/New_York'); //Get current date and time. $current_time = date('Y-m-d H:i:s'); //Set reservation time variable $res_datetime = $_POST['res_datetime']; //Set event time. $event_time = strtotime($res_datetime); ?> <!doctype html> <html> <head> <meta charset="utf-8"> <title>Check Date and Time</title> </head> <?php //Check to be sure reservation time is at least one hour in the future. if (($current_time - $event_time) <= (3600)) { echo "You must make a reservation at least one hour ahead of time."; } ?> <form name="datetime" action="" method="post"> <input name="res_datetime" type="datetime-local" id="res_datetime"> <input type="submit"> </form> <body> </body> </html> How can I create a validation check to make sure the date and time of the reservation is at least one hour ahead of time?

  • Searching with a UISearchbar is slow and blocking the main thread.

    - by Robert
    I have a Table with over 3000 entries and searching is very slow. At the moment I am doing just like in the 'TableSearch' example code (but without scopes) - (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString { [self filterContentForSearchText: searchString]; // Return YES to cause the search result table view to be reloaded. return YES; } And the filterContentForSearchText method is as follows: - (void) filterContentForSearchText:(NSString*)searchText { // Update the filtered array based on the search text // First clear the filtered array. [filteredListContent removeAllObjects]; // Search the main list whose name matches searchText // add items that match to the filtered array. if (fetchedResultsController.fetchedObjects) { for (id object in fetchedResultsController.fetchedObjects) { NSString* searchTarget = [tableTypeDelegate getStringForSearchFilteringFromObject:object]; if ([searchTarget rangeOfString:searchText options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch)].location != NSNotFound) { [filteredListContent addObject:object]; } } } } My question is twofold: How do can I make the searching process faster? How can I stop the search from blocking the main thread? i.e. stop it preventing the user from typing more characters. For the second part, I tried "performSelector:withObject:afterDelay:" and "cancelPreviousPerformRequests..." without much success. I suspect that I will need to use threading instead, but I do not have much experience with it.

  • How to remove an object from the canvas?

    - by Marius Jonsson
    Hello there, I am making this script that will rotate a needle on a tachometer using canvas. I am a newbie to this canvas. This is my code: function startup() { var canvas = document.getElementById('canvas'); var context = canvas.getContext('2d'); var meter = new Image(); meter.src = 'background.png'; var pin = new Image(); pin.src = 'needle.png'; context.drawImage(meter,0,0); context.translate(275,297); for (var frm = 0; frm < 6000; frm++){ var r=frm/1000; //handle here var i=r*36-27; //angle of rotation from value of r and span var angleInRadians = 3.14159265 * i/180; //converting degree to radian context.rotate(angleInRadians); //rotating by angle context.drawImage(pin,-250,-3); //adjusting pin center at meter center } } Here is the script in action: http://www.kingoslo.com/instruments/ The problem is, as you can see, that the red needle is not removed beetween each for-loop. What I need to do is to clear the canvas for the pin object between each cycle of the loop. How do I do this? Thanks. Kind regards, Marius

  • UISlider won't display

  • Visual Studio identical token highlighting

    - by dsteinweg
    I coded a Mancala game in Java for a college class this past spring, and I used the Eclipse IDE to write it. One of the great (and fairly simple) visual aids in Eclipse is if you select a particular token, say a declared variable, then the IDE will automatically highlight all other references to that token on your screen. Notepad++, my preferred Notepad replacement, also does this. Another neat and similar feature in Eclipse was the vertical "error bar" to the right of your code (not sure what to call it). It display little red boxes for all of the syntax errors in your document, yellow boxes for warnings like "variable declared but not used", and if you select a word, boxes appear in the bar for each occurance of the word in the document. A screenshot of these features in action: After a half hour of searching, I've determined that Visual Studio cannot do this on its own, so my question is: does anyone know of any add-ins for 2005 or 2008 that can provide either one of the aforementioned features? Being able to highlight the current line your cursor is on would be nice too. I believe the add-in ReSharper can do this, but I'd prefer to use a free add-in rather than purchase one.

  • two controllers in one layout, rails 3

    - by Grizlord
    Okay, I have two models, a recipe model and a category model. In my layout(application.html.erb) I have a main container div that "yields" the recipes index action. I'm trying to list all the category names as links in a side bar(also a div) by iterating over them in an unordered list. When you click one of the links it will go to the category show page which will then list all the recipes in that category. Here is how I'm trying to list the links in - <div class="container" id="categories"> <% for category in @categories %> <ul> <li><%= link_to category.name, category %></li> </ul> <% end %> </div> The problem is I get a NoMethodError - You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.each It is not retrieving the records from the model. Any suggestions on how to get this done would be greatly appreciated. I tried to render a partial as some of the other similar posts have said but still get the same error. This is the exact error - NoMethodError in Recipes#index Showing /Users/grizlord/Rails/recipe2/app/views/layouts/application.html.erb where line #39 raised: You have a nil object when you didn't expect it!

  • UIButton only responds in a small area

    I'm trying to add a UIButton to a UIView, but am having some trouble with getting it to respond to touches. I have a method which returns UIButtons after I provide it with a tag: - (UIButton*)niceSizeButtonWithTag:(int)tag { UIButton * aButton = [UIButton buttonWithType:UIButtonTypeCustom]; [aButton setTag:tag]; [aButton addTarget:self action:@selector(buttonWasTapped:) forControlEvents:UIControlEventTouchUpInside]; CGRect newFrame = aButton.frame; newFrame.size.width = 44; newFrame.size.height = 44; [aButton setFrame:newFrame]; return aButton; } As you can see I'm creating a new button and increasing the size. I use this in the following way: UIButton * anotherButton = [self niceSizeButtonWithTag:1]; [anotherButton setImage:[UIImage imageNamed:@"image" withExtension:@"png"] forState:UIControlStateNormal]; [anotherButton setCenter:CGPointMake(middleOfView)]; [aView addSubview:anotherButton]; I create a lot of buttons like this, hence the reason for the method. The buttons are always created and added to the subview perfectly. I can see the image and they're in the correct position. The problem is that they only respond to touches in a tiny strip. In this attached image, The yellow shows the whole frame of the button, The red shows the area that will respond to touches. The grey shows a section of the view the button is added to. If anyone could shed some light on why this is happening, it would be really useful.

  • Redirecting users after destroy

    - by mathee
    I have 3 models: Questions, Answers, and Profiles (I know, it should be called "Users"). When you view a question Q, I query the database for the answers to Q. (They are linked by id.) In the view, the current user has the option to delete his answer by clicking on the destroy link displayed next to his answer: %table %tr %td Answers: - @answers.each do |a| %tr %td - @provider = Profile.find(a.provider) %i #{h @provider.username} said: %br #{h a.description} %td = link_to 'View full answer', a %td - if a.provider == @profile.id #{link_to 'Delete my answer', a, :confirm => 'Are you sure?', :method => :delete} The problem is that when the user clicks on the destroy link, it redirects to the /answers/index. I want it to redirect to /questions/Q. What's the best way to do this? I know that there's a redirect_to method, but I don't know how to implement it when I want to redirect to an action for a different controller. It also needs to remember the question from which the answer is being deleted. I tried passing something like :question_id in link_to as: #{link_to 'Delete my answer', a, :confirm => 'Are you sure?', :question_id => @question.id, :method => :delete} In AnswersController#destroy: def destroy @answer = Answer.find(params[:id]) @answer.destroy respond_to do |format| format.html { redirect_to(answers_url) } format.xml { head :ok } end @question = Question.find(params[:question_id]) redirect_to question_path(@question) end The :question_id information is not passed to the destroy method, so I get this error: Couldn't find Question without an ID To confirm, I added a puts call before Question.find, and it returned nil.

  • How do you parse the XDG/gnome/kde menu/desktop item structure in c++??

    - by Joe Soul-bringer
    I would like to parse the menu structure for Gnome Panels (the standard Gnome Desktop application launcher) and it's KDE equivalent using c/c++ function calls. That is, I'd like a list of what the base menu categories and submenu are installed in a given machine. I would like to do with using fairly simple c/c++ function calls (with NO shelling out please). I understand that these menus are in the standard xdg format. I understand that this menu structure is stored in xml files such as: /home/user/.config/menus/applications.menu I've look here: http://www.freedesktop.org/wiki/Specifications/menu-spec?action=show&redirect=Standards%2Fmenu-spec but all they offer is the standard and some shell files to insert item entries (I don't want shell scripts, I don't want installation, I definitely don't want to create a c-library from the XDG specification. I want to find the existing menu structure). I've looked here: http://library.gnome.org/admin/system-admin-guide/stable/menustructure-13.html.en for more notes on these structures. None of this gives me a good idea of how determine the menu structures using a c/c++ program. The actual gnome menu structures seem to be a horrifically hairy things - they don't seem to show the menu structure but to give an XML-coded description of all the changes that the menus have gone through since installation. I assume gnome panels parses these file so there's a function buried somewhere to do this but I've yet to find where that function is after scanning library.gnome.org for a couple of days. I've scanned the Nautilus source code as well but Panels seem to exist elsewhere or are burried well. Thanks in advance
