  • Flex: Change line height of Label component

    - by ChrisInCambo
    Hi guys, Maybe I'm googling for the wrong thing but I can't find anything on this. How can I change the line height of a Label element in Flex? I have two labels in a VBox and there is quite a lot of white space between them which I would like to reduce. There's no line height property and setting the height property causes overlap. Thanks in advance for any help! Cheers, Chris

  • Why is my django bulk database population so slow and frequently failing?

    - by bryn
    I decided I'd like to use django's model system rather than coding raw SQL to interface with my database, but I am having a problem that surely is avoidable. My models.py contains: class Student(models.Model): student_id = models.IntegerField(unique = True) form = models.CharField(max_length = 10) preferred = models.CharField(max_length = 70) surname = models.CharField(max_length = 70) and I'm populating it by looping through a list as follows: from models import Student for id, frm, pref, sname in large_list_of_data: s = Student(student_id = id, form = frm, preferred = pref, surname = sname) s.save() I don't really want to be saving this to the database each time but I don't know another way to get django to not forget about it (I'd rather add all the rows and then do a single commit). There are two problems with the code as it stands. It's slow -- about 20 students get updated each second. It doesn't even make it through large_list_of_data, instead throwing a DatabaseError saying "unable to open database file". (Possibly because I'm using sqlite3.) My question is: How can I stop these two things from happening? I'm guessing that the root of both problems is that I've got the s.save() but I don't see a way of easily batching the students up and then saving them in one commit to the database.

  • Class not overwriting with addClass

    - by scatteredbomb
    I'm using jQuery's addClass to add a class to an tab so when clicked it'll change the class so it's obvious the tab is highlighted. My HTML <div id="mainNav"> <ul> <li id="LinktheBand" onclick="nav('theBand')">The Band</li> <li id="linkTheMusic" onclick="nav('theMusic')">The Music</li> My CSS #mainNav li { float:left; margin-right:5px; color:white; font-family:Tahoma; font-weight:bold; padding: 10px 8px 0px 8px; background:url('../images/transparent-65.png'); height:40px; height: 25px !important; border:1px solid #000; } #mainNav li:hover { float:left; margin-right:5px; color:white; font-family:Tahoma; font-weight:bold; padding: 10px 8px 0px 8px; background: #660000; height:40px; height: 25px !important; border:1px solid #660000; } .mainNavSelected { float:left; margin-right:5px; color:white; font-family:Tahoma; font-weight:bold; padding: 10px 8px 0px 8px; background: #660000; height:40px; height: 25px !important; border:1px solid #660000; } My Javascript function nav(a) { $('#'+a).show(); $('#Link'+a).addClass('mainNavSelected'); } This works properly, I check firebug and can see the class="mainNavSelected" is added, but the list element doesn't take any properties of the new class. Firebug lists all the class items for mainNavSelected, but has them all crossed out. What am i missing to replace the class of this element?

  • Detect click events outside div inside usercontrol

    - by toraan
    I have a div inside a user control that is displayed by the user after some event. I want to hide this div when user clicks anywhere elese on the page but not on the div (or not on any element that is inside the div). If it wasn't a user control I could use body's clieck event to check the target, but because this is usercontrol that is hosted by other page I can't just "play" with it's elements. How can I achieve that without using body of the hosting page?

  • iPhone RSS thumbnail

    I have a simple RSS reader. Stories are downloaded, put into a UITableView, and when you click it, each story loads in a UIWebView. It works great. Now though, I'd like to incorporate an image on the left side (like you'd see in the YouTube app). However, since my app pulls from an RSS feed, I can't simply specify image X to appear in row X because row X will be row Y tomorrow, and things will get out of order, you know? I am currently pulling from a YouTube RSS feed, and can get the video title, description, publication date, but I'm stuck as to how to pull the little thumbnail besides each entry in the feed. As you can probably tell, I'm a coding newbie (this being my first application other than a Hello World app) and I'm getting so frustrated by my own lack of knowledge. Thanks! BTW, here's some sample code: - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{ //NSLog(@"found this element: %@", elementName); if (currentElement) { [currentElement release]; currentElement = nil; } currentElement = [elementName copy]; if ([elementName isEqualToString:@"item"]) { // clear out our story item caches... item = [[NSMutableDictionary alloc] init]; currentTitle = [[NSMutableString alloc] init]; currentDate = [[NSMutableString alloc] init]; currentSummary = [[NSMutableString alloc] init]; currentLink = [[NSMutableString alloc] init]; } } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{ //NSLog(@"ended element: %@", elementName); if ([elementName isEqualToString:@"item"]) { // save values to an item, then store that item into the array... [item setObject:currentTitle forKey:@"title"]; [item setObject:currentLink forKey:@"link"]; [item setObject:currentSummary forKey:@"summary"]; [item setObject:currentDate forKey:@"date"]; [stories addObject:[item copy]]; NSLog(@"adding story: %@", currentTitle); } } - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{ //NSLog(@"found characters: %@", string); // save the characters for the current item... if ([currentElement isEqualToString:@"title"]) { [currentTitle appendString:string]; } else if ([currentElement isEqualToString:@"link"]) { [currentLink appendString:string]; } else if ([currentElement isEqualToString:@"description"]) { [currentSummary appendString:string]; } else if ([currentElement isEqualToString:@"pubDate"]) { [currentDate appendString:string]; } }

Or at least, how could i modify the javascript code to make it work in both internet browsers?

  • Updating ToolStripProgressBar and ToolStripStatusLabel along with with an action

    - by TChristian
    In a Windows Form, I have a search box that fires an event to search a remote database and display some results. The query is pretty fast, usually just a fraction of a second, but in case the delay is noticeable there is a progress bar and label in the form's status bar. When the user clicks "Search" the status label should appear and the progress bar show some progress. Then when the result comes back the label should disappear and the progress bar should be full. Pretty basic response. The problem is, I can't get those actions to happen in that order. Using the code below, I click "Search", nothing happens until the results are displayed, and then the progress bar fills up from 0 to 100. The label never appears. I even threw in a sleep command immediately after the event to be sure I wasn't just missing it, but it's as if the first 2 statements are not being executed. What am I doing wrong here? private void searchButton_Click(object sender, EventArgs e) { toolStripStatusLabel1.Visible = true; toolStripProgressBar1.Value = 20; m_changeRequestedEvents.Fire<String>("SearchTerm", searchTextBox.Text); toolStripProgressBar1.Value = 100; toolStripStatusLabel1.Visible = false; }

  • Soften a colour border, maybe with a gradient, programmatically.

    - by ProfK
    I have a narrow header in corporate colour, bright red, with the content below on a just-off-white background. Ive tried softening the long line where these colours meet using border type divs with intermediate backgrounds, but I think I need the original type curved gradient 'area transitions'. I could copy the 1024px wide, and too narrow (vertically), header gif from their web site, and chop it up for eight border images, but that seems clumsy, and I'm looking for something I can apply anywhere, without needing images. I am able to do round borders in the x-y plane, but I'm curious as to how I can apply a gradient to any chosen colour transition. The extra divs I'm using as border elements above and below '#top-section' arose when I was toying with making many divs for one bordered element. This seemed the ultimate in border manipulation, sans code, but very tedious to spec in CSS and lay out a new border for each bordered element. <div id="topsection"> <div style="float: right; width: 300px; padding-right: 5px;"> <div style="font-size: small; text-align: right;"> Provantage Media Management System</div> <div style="font-size: x-small; text-align: right;"> <asp:LoginStatus ID="loginStatus" runat="server" LoginText="Log in" LogoutText="Log out" /> </div> </div> <span style="padding-left: 15px;">Main Menu</span><span id="content-title"> <asp:ContentPlaceHolder ID="titlePlaceHolder" runat="server"> </asp:ContentPlaceHolder> </span> <div style="background-color: white; height: 2px;"> </div> <div style="background-color: white; height: 3px;"></div> And the CSS: #topsection { background-color: #EB2728; color: white; height: 35px; font-size: large; font-weight: bold; }

  • SVG Parser in Javascript

    - by jsight
    I believe that at one point, I saw a TinySVG implementation that worked in the browser, using the canvas element as the backend. I found a few sites that appeared to indicate it was at http://fuchsia-design.com/CanvaSVG/, however, that site appears to no longer exist. Is this project (or a similar one) still on the web anywhere?

  • Temporary Onmouseover

    - by 2x2p1p
    Hi guys :) Css "over" selector applys a temporary style to an element, it isn't definitive: div:hover { background-color: red; } I can use the same thing with javascript but it is a bit complicate and impossible for several elements: var elem = document.getElementByTagName ("div")[0]; elem.onmouseover = function () { this.style.backgroundColor = "red"; } elem.onmouseout = function () { this.style.backgroundColor = "transparent"; } There is a better way ? Something like this: document.getElementByTagName ("div")[0].ontemporarymouseover = function () { // LoL this.style.backgroundColor = "red"; } Thanks

  • How to do HABTM management with auto completion in Rails?

    - by Andrei
    I am looking for a good solution for a probably typical problem of managing models with HABTM association in Rails. Let's assume that we have two models -- products and categories: Products has_many :categorizations has_many :categories, :through => :categorizations Categories has_many :categorizations has_many :products, :through => :categorizations Categorization belongs_to :product belongs_to :category Pat Shaughnessy is developing modified auto_complete plugin which can allow to manage one-to-many (and many-to-many) association: For someone that would be enough, but I don't really like so many text fields. I guess it is possible to combine the Ryan Bates' screencasts used by Pat in a slightly different way, namely, using one text field with autocomplete: Also it would be better to remove from the list of suggested tasks (one-to-many), or products|categories (many-to-many) those which have been already added. In the case of products-categories relationship, such auto completion would be used both in the form for product, and in the form for category. I hope that there is an existing plugin for that. I am not very experienced in Ruby, and don't really know how to implement such logic by myself. Any help is appreciated!

  • Why can't I get the value of this text input?

    - by Spilot
    It seems simple enough, but nothing I try is working. I have a jquery ui datepicker, I use val() to get the value of that input on button click(), then log it. The click event is working. I can log a string I write myself, but when I pass console.log() the variable that stores the datepicker value...nothing. I've tried using html() and text() instead of val(), still nothing //JS $(function(){ $("button").button(); $("#date").datepicker(); var date = $("#date").val(); $("button").click(function(){ // this logs console.log("event working"); // but this logs nothing console.log(date); });//close click });//closes function //HTML <!DOCTYPE html> <html> <head> <script src="http://www.parsecdn.com/js/parse-1.2.8.min.js"></script> <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script> <script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script> <link rel="stylesheet" href="http://myDomain/bn/lbStyle.css"/> <script src="http://myDomain/index.js"></script> <title> Welcome to The Bringer Network </title> </head> <body> <form id="dialog"> <p>Date <input type="text" id="date"/></p> <button>Submit</button> </form> </body> </html>

  • formtastic weird month name display

    - by Alexey Poimtsev
    Hi, i'm using formtastic, all is ok, but strange thing - on = form.input :birthdate, :as => :date it renders to something like <li><label for="profile_birthdate_2i">Month</label><select id="profile_birthdate_2i" name="profile[birthdate(2i)]"> <option value="1">114</option> <option value="2">97</option> <option value="3">110</option> <option value="4">115</option> <option value="5">108</option> <option value="6">97</option> <option value="7">116</option> <option value="8">105</option> <option value="9">111</option> <option value="10">110</option> <option value="11">32</option> <option value="12">109</option> </select> but if i'm using in semantic_form something like = form.datetime_select :birthdate it renders correctly. I've found information, that it may be caused by locale file with no translations for month names, but its so strange - why rails helpers renders month names ok, but formtastic - not :( any ideas?

  • How to share the credentials between Webform and Winform?

    - by Daniel
    Hi! Question: I want to make a login form at the Clickonce deployment webpage, and only allow the authenticated users to download the application. and I want the downloaded application to use the same credentials entered at the webpage, without prompting the users to enter the credentials again. Details: I have an application(Windows Client) which needs customized settings for different users. the application is deployed through ClickOnce. Currently, the users are given the ClickOnce webpage URL, then download the application from there. after download and running the application, the application prompts users with a login form. If their credentials are authenticated, the application loads the customized settings from the server's database according to the credentials given. The problem is, any unauthenticated users can download the application if they just know the ClickOnce deployement webpage's URL. Unauthenticated users won't be able to run the application anyways, because the application asks for credentials when started, but I want to prevent the unauthenticated users from downloading the application at all. Am I asking the wrong question maybe? Your help is much appreciated!

  • advanced winform framework

    - by alfredo dobrekk
    Hi, i m starting a new project that would basically take input from user and save them to database among about 30 screens, and i would like to find a framework that will allow the maximum number of these features out of the box : .net c#. windows form. unit testing continuous integration screens with lists, combo boxes, text boxes, add, delete, save, cancel that are easy to update when you add a property to your classes or a field to your database. auto completion on controls to help user find its way use of an orm like nhibernate easy multithreading and display of wait screens for user easy undo redo tabbed child windows search forms ability to grant access to some functionnalities according to user profiles mvp/mvvm or whatever design patterns either some code generation from database to c# classe or generation of database schema from c# classes some kind of database versioning / upgrade to easily update database when i release patches to application once in production code metrics analysis some code generator i can use against my entities that would generate some rough form i can rearrange after code documentation generator ... Any ideas ? I know its lot but i really would like to use existing code to build upon so i can focus on business rules. Do u have any suggestion to add to the list before starting ? What open source tools would u use to achieve these ?
