  • Android vertical line xml

    - by Kaspa
    Hello, I'm trying to figure out how to define a verical line (1px thick) to be used as a drawable. to make a horizontal one, it's pretty straightforward: <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="line"> <stroke android:width="1dp" android:color="#0000FF"/> <size android:height="50dp" /> </shape> The question is, how to make this line vertical? Yes, there are workarounds, such as drawing a rectangle shape 1px thick, but that complicates the drawable xml, if it consists of multiple <item> elements. Anyone had any chance with this?

  • In Ada how do I initialise an array constant with a repeated number?

    - by mat_geek
    I need an array of 820 zeors for using with a mathematical function. In C I could just write the following and the compiler would fill the array: const float EMPTY_NUMBER_A[820] = { 0.0, }; However in Ada that isn't possible. I really don't want to hard code the 820 elements as 0.0. Is there a way to get the compiler to do it? type Number_A is array (1 .. 820) of Float; EMPTY_NUMBER_A : constant Number_A := something; Using Ada 95 and GNAT.

  • ContentEditable DIV - disabling drag and drop

    - by sonofdelphi
    Is it possible to disable the drag-and-drop functionality on elements which have the contentEditable attribute set to true. I have the following HTML page. <!DOCTYPE html> <html><meta charset="utf-8"><head><title>ContentEditable</title></head> <body> <div contenteditable="true">This is editable content</div> <span>This is not editable content</span> <img src="bookmark.png" title="Click to do foo" onclick= "foo()"> </span> </body> </html> The main problem I'm facing is that it is possible to drag and drop the image into the DIV and it gets copied (along with the title and the click handler)

  • Modal MessageBox for ASP.NET without jQuery

    - by Joe
    I have an assembly with custom ASP.NET server controls that is used in several, mostly in-house, ASP.NET 2.0 applications. The server controls use simple modal popup messageboxes, which are currently implemented using the javascript alert and confirm functions. I want to release a new version of this assembly that uses a better solution for messageboxes, including support for Yes/No buttons. The appearance would be something like a simplified version of the Ajax Control Toolkit ModalPopup extender (sample here). My constraints are that this should be as easy as possible to integrate into existing ASP.NET 2.0 applications without introducing new dependencies: ideally just drop in a new version of the assembly, that contains all the javascript it needs as an embedded resource, and possibly a CSS file. Because of this constraint, I am not considering solutions I've seen that use jquery, or the ASP.NET Ajax Control Toolkit, which appears to require adding elements to pages that use the extenders (ScriptManagers and the like). Any recommendations?

  • Why use wmode at all?

    - by Captain Phoenix
    What benefit does using wmode give if you're not needing transparency? I've look through this forum and found posts talking about the different wmode attributes here, but I want to know why I need to use it in the first place and if removing it will break anything else. My application uses wmode="opaque" at the moment but it seems to stop scrolling in Firefox. I use JavaScript focus() to allow the user to type directly into the flash ap. Otherwise I'm using the stock standard Flex Builder 3 HTML template. Edit: The ap uses the whole page, without any additional elements needing to be displayed over the flash part.

  • Iphone NSXMLParser NSCFString memory leak

    - by atticusalien
    I am building an app that parses an rss feed. In the app there are two different types of feeds with different names for the elements in the feed, so I have created an NSXMLParser NSObject that takes the name of the elements of each feed before parsing. Here is my code: NewsFeedParser.h #import @interface NewsFeedParser : NSObject { NSInteger NewsSelectedCategory; NSXMLParser *NSXMLNewsParser; NSMutableArray *newsCategories; NSMutableDictionary *NewsItem; NSMutableString *NewsCurrentElement, *NewsCurrentElement1, *NewsCurrentElement2, *NewsCurrentElement3; NSString *NewsItemType, *NewsElement1, *NewsElement2, *NewsElement3; NSInteger NewsNumElements; } - (void) parseXMLFileAtURL:(NSString *)URL; @property(nonatomic, retain) NSString *NewsItemType; @property(nonatomic, retain) NSString *NewsElement1; @property(nonatomic, retain) NSString *NewsElement2; @property(nonatomic, retain) NSString *NewsElement3; @property(nonatomic, retain) NSMutableArray *newsCategories; @property(assign, nonatomic) NSInteger NewsNumElements; @end NewsFeedParser.m #import "NewsFeedParser.h" @implementation NewsFeedParser @synthesize NewsItemType; @synthesize NewsElement1; @synthesize NewsElement2; @synthesize NewsElement3; @synthesize newsCategories; @synthesize NewsNumElements; - (void)parserDidStartDocument:(NSXMLParser *)parser{ } - (void)parseXMLFileAtURL:(NSString *)URL { newsCategories = [[NSMutableArray alloc] init]; URL = [URL stringByReplacingOccurrencesOfString:@" " withString:@""]; URL = [URL stringByReplacingOccurrencesOfString:@"\n" withString:@""]; URL = [URL stringByReplacingOccurrencesOfString:@" " withString:@""]; //you must then convert the path to a proper NSURL or it won't work NSURL *xmlURL = [NSURL URLWithString:URL]; // here, for some reason you have to use NSClassFromString when trying to alloc NSXMLParser, otherwise you will get an object not found error // this may be necessary only for the toolchain [[NSURLCache sharedURLCache] setMemoryCapacity:0]; [[NSURLCache sharedURLCache] setDiskCapacity:0]; NSXMLNewsParser = [[NSXMLParser alloc] initWithContentsOfURL:xmlURL]; // Set self as the delegate of the parser so that it will receive the parser delegate methods callbacks.

Here is a screen shot of the Leaks instrument with the NSCFStrings leaking: http://img139.imageshack.us/img139/3997/leaks.png For the life of me I can't figure out where these leaks are coming from. Any help would be greatly appreciated.

  • Flow diagram in html/css

    - by viraptor
    Hi, is there some good way to create a flow / swimline diagram without resorting to scripting or tables? I'm talking about showing different hosts sending packets (so hosts on the X axis, time on the Y and arrows to the destination host). It seems like too much elements for tables (especially the arrows spanning multiple columns either way), but on the other hand, divs would be hard to position in the right place horizontally (they'd have to be basically aligned to a specified "column"). Is there any good way out? Any helper frameworks? (I don't want to do canvas stuff unless really needed)

  • Change an input's HTML5 placeholder color with CSS

    - by David Murdoch
    Chrome supports the placeholder attribute on input[type=text] elements (others probably do too). But the following CSS doesn't do diddly squat: <style> input[placeholder], [placeholder], *[placeholder] { color:red !important; } </style> <input type="text" placeholder="Value" /> "Value" will still be grey (er, gray. whatever) instead of red. Is there are way to change the color of the placeholder text? p.s. I'm already using the jQuery placeholder plugin for the browsers that don't support the placeholder attribute natively.

  • How to give INSTALLDIR folder permission in WIX?

    - by tete
    I am designing a WIX 3.6 installer project, during the installation we need to grand the user create file permission to the install folder(INSTALLDIR, especially with the default install folder, the Program Files, the user normally can't create file in the installation. We've experienced some failures). I guess it can be achieved by setting a Permission element, with CreateFile property. However, the INSTALLDIR is a directory, and only such elements as CreateFolder, File, FileShare, Registry, ServiceInstall can have permission element. So could anyone tell me how to do that? My directory declaration is something like this: <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="ProgramFiles64Folder"> <Directory Id='MANUFACTUREFOLDER' Name='$(var.ManufacturerName)'> <Directory Id="INSTALLDIR" Name="$(var.ProductName)"> Thanks!

  • jquery set focus on dynamic content?

    - by Alan
    In jquery I've appended a <li> element to an unordered list. How do I focus on the newly created <li> ? If I do the following: $("ul").append('<li><input type="text">hi!</input></li>'); $("li:last").focus(); //doesn't work because new <li> isn't in dom yet the focus doesn't work, as noted above. I know jquery 1.4.2 has a live() event handler which allows you load event handlers to dynamically added elements, but I'm not sure what I'm doing wrong: $(document).ready(function () { $('li').live('load', function () { alert("hi!"); $("li:last").focus(); }); });

  • Webbrowser control: Get text value from html text

    - by Khou
    The web browser has the following displayed content, within a html table. [Element] [Value] Name John Smith Email [email protected] We know that the value of the elements are on to the right of the element and they are both on the same line (this is how it appears on the screen but in the html code it might not appear like this). How do you get the values of element name and element email? (first remove all html tag? then somehow use regular express to get the values? or figure out how to use html agility pack?)

  • Webrat says it can't find some text, but the text is actually there

    - by Jason
    I have a webpage that has a form button on it called "delete", and a cuke scenario that has the line: And I should see "delete" When I run the scenario, I get this error: expected the following element's content to include "delete" ...and it dumps the webrat page to stdout and the "delete" is, in fact, not there. So far so good. However, when I tell webrat to show me the page before the error happens: Then show me the page And I should see "delete" ...Safari fires up and shows me the page, and in Safari there's the "delete" button, totally there. Why is webrat not finding the form button? I've also had this same problem with form fields, such as text inputs that have a value in them when the page loads, but webrat says there's nothing there. Looking at it in Safari shows, again, that the field does have the right text in it. Is this a bug, or is webrat just not suitable for checking form elements? Is there a different way to do this? Thanks!

  • jquery animation callback - how to pass parameters to callback

    - by Hans
    I´m building a jquery animation from a multidimensional array, and in the callback of each iteration i would like to use an element of the array. However somehow I always end up with last element of the array instead of all different elements. html: <div id="square" style="background-color: #33ff33; width: 100px; height: 100px; position: absolute; left: 100px;"></div> javascript: $(document).ready(function () { // Array with Label, Left pixels and Animation Lenght (ms) LoopArr = new Array( new Array(['Dog', 50, 500]), new Array(['Cat', 150, 5000]), new Array(['Cow', 200, 1500]) ); $('#square').click(function() { for (x in LoopArr) { $("#square").animate({ left: LoopArr[x][0][1] }, LoopArr[x][0][2], function() { alert (LoopArr[x][0][0]); }); } }); }); ` Current result: Cow, Cow, Cow Desired result: Dog, Cat, Cow How can I make sure the relevant array element is returned in the callback?

  • prolog program to find equality of two lists in any order

    - by Happy Mittal
    I wanted to write a prolog program to find equality of two lists, the order of elements doesn't matter. So I wrote following: del( _ , [ ] , [ ] ) . del( X , [ X|T ] , T ). del( X , [ H|T ] , [ H|T1 ] ) :- X \= H , del( X , T , T1 ). member( X, [ X | _ ] ) . member( X, [ _ | T ] ) :- member( X, T ). equal( [ ], [ ] ). equal( [X], [X] ). equal( [H1|T], L2 ) :- member( H1, L2 ), del( H1, L2, L3), equal(T , L3 ). But when I give input like equal([1,2,3],X)., it doesn't show all possible values of X. instead the program hangs in the middle. What could be the reason?

  • How to redirect if javaScript is disabled?

    I have a site which relies heavily on javaScript. I created a mirror site, which has all the JS as well as all the elements that require JS removed. What is a good, easy way to redirect users to the mirror site if they don't have javaScript enabled? I tried this, but it doesn't seem very good: <noscript> <meta http-equiv="refresh" content="0; URL=nojs/index.php"> </noscript> I also tried to putting header-redirect into the meta tag, but that didn't work.

  • WPF listbox : problem with selection

    - by KiTe
    Hello. In my XAML file, I have a ListBox declared like this : <ListBox x:Name="lstDeck" Height="280" ItemsSource="{Binding Path=Deck}" > <ListBox.ItemTemplate> <DataTemplate> <ListBoxItem Content="{Binding}" /> </DataTemplate> </ListBox.ItemTemplate> </ListBox> In my view model, Deck is an ObservableCollection, so that binding directly displays the content of my collection. But when I have several value that hold the same value (for example "10" six times), the selection in the ListBox has a weird behaviour : it select 2-3 elements instead of the only the one on which I clicked. Moreover, when I click to another listBoxItem, it doesn't unfocus the previous selected one. Then it is impossible to see which item is actually selected, and impossible to get the SelectedIndex value. Has someone an idea?

  • Math problem: Determine the corner radius of an inner border based on outer corner radius/thickness

    - by chaiguy
    Here's a math/geometry problem for the math whizzes (not my strongest subject). This is for WPF, but should be general enough to solve regardless: I have two embedded Border elements, with the outer one having a certain corner radius, R and border thickness, T. Given these two values, what should the corner radius of the inner Border, R' be set to such that the two corner edges meet with no overlap or holes? So far I've just been eyeballing it, but if someone can give me a proper formula that would be great. Respect points if you can!! ;)

  • Create a Generic IEnumerable<T> given a IEnumerable and the member datatypes

    - by ilias
    Hi, I get an IEnumerable which I know is a object array. I also know the datatype of the elements. Now I need to cast this to an IEnumerable<T, where T is a supplied type. For instance IEnumerable results = GetUsers(); IEnumerable<T> users = ConvertToTypedIEnumerable(results, typeof(User)); I now want to cast/ convert this to IEnumerable<User. Also, I want to be able to do this for any type. I cannot use IEnumerable.Cast<, because for that I have to know the type to cast it to at compile time, which I don't have. I get the type and the IEnumerable at runtime. - Thanks

  • How to page while maintaining the querystring values in ASP.Net Mvc 2

    - by Picflight
    I am using the pager provided by Martijin Boland to implementing paging in my Asp.Net Mvc 2 application. My form uses the GET method to send all parameters to the querystring, it is a search form with several form elements. <% using (Html.BeginForm("SearchResults", "Search", FormMethod.Get)) {%> On the SearchResults View I am trying to implement paging: <div class="pager"> <%= Html.Pager(Model.PageSize, Model.PageNumber, Model.TotalItemCount, new { Request.QueryString })%> </div> The Html.Pager has some overloads which I am not too clear on how to use. The Request.QueryString makes the querystring look like this: http://localhost:1155/Search/SearchResults?QueryString=Distance%3D10%26txtZip%3D%26cb&page=2 Should it not be like this? http://localhost:1155/Search/SearchResults?Distance=20&txtZip=10021&page=2

  • What's viewport mean to the jQuery guys?

    - by justSteve
    I came here intent on asking a 'how do i' type question focused on a particular UI problem i have to solve and i started using the term 'viewport'. Seems there's lots of contexts that tag evokes. Before i outline mine i should ask - is there a generally recognized consensus as to what a 'viewport' is? Any gallery or object browser that focuses on a UI principle where multiple frames/panes show feeds of different graphs where each feed might be a complex grid/graph? I'm imagining something where my page may open with a half dozen different grids (tabular data) stay updated via ajax interactions with various servers. UI elements provide control scale up or down a given grid with a quasi accordion slide kinda thingie. For example, one click on a scale up-or-down control would rescale the other viewports in the opposite direction. More clicks - more pronounced effect. So my 'how do i' question morphs into a 'how have others...' thx

  • How to access the Principal from a Java service object without using FlexContext?

    - by Marplesoft
    We're building some Java objects that are exposed via BlazeDS to our flex client application. So basically the BlazeDS messagebroker servlet instantiates and invokes methods on these objects in response to client requests. Works great. We're using app server-based authentication and have set up a security constraint on the <destination> elements in the remoting-config.xml file element to prevent unauthenticated clients from being able to access these remote java objects. Again, works fine. However, there are several places within the implementation of these java objects where we want to get the currently logged on user's username. Right now we are doing this via FlexContext.getUserPrincipal(), which gives access to this but we have a nagging concern that we don't like the idea that the implementation of these objects (the service layer) has a hard dependency on a BlazeDS class. But we're not sure how else to get access to this. The same applies to accessing the ServletContext and such. Any ideas?
