  • jquery show hidden div

    - by Fahad
    Firstly, I'm sort of embarrassed asking about this, so many people have already asked this question but even after having gone through so many posts, I'm unable to achieve what I want. Basically, a div, initially hidden, has to be displayed on a button click. I tried hiding the div using display:none and hide() and then displaying it using show(), toggle(), and css("display","block"). Using all sorts of combinations of the above, I was still unable to get the result. Code: <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> <link href="css/smoothness/jquery-ui-1.9.2.custom.min.css" rel="stylesheet" type="text/css" /> <script src="jQuery/jquery-1.8.3.min.js" type="text/javascript"></script> <script src="jQuery/jquery-ui-1.9.2.custom.min.js" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function () { $('#one').hide(); $('#Button1').click(function () { $('#one').toggle(500); }); }); </script> </head> <body> <form id="form1" runat="server"> <div id="one" style="height: 20px;width:200px; background-color: Red; "> </div> <asp:Button ID="Button1" runat="server" Text="Show" /> </form> </body> </html> On button click, the div is shown for a brief second before it disappears again. The same thing happens if I use show() instead of toggle() in the above code. Again the same thing if I set style="display:none" to the div instead of using hide() and then use show() or toggle(). I also tried using $('#one').css("display","block"); but again, the same result. Can anyone please tell me where I'm going wrong. Just started learning jQuery and it is really frustrating when something apparently so simple will not work. Thanks in advance. :)

  • linking c++ sources in iPhone project

    - by Steve918
    I have a single cpp file added to my iPhone project with a .cpp extension, but I'm seeing errors when linking like: operator new[](unsigned long)", referenced from: ___gxx_personality_sj0", referenced from: I thought as long as I named the cpp files with .cpp or .mm it would do the right thing, do I need to add some linker flags? Update: Complete Build log: http://dpaste.org/tXAy/ The C++ code: unzip.h unzip.cpp

  • How do I get TextMate style quotes in Emacs?

    - by pdcawley
    In textmate, when there's a current selection, I hit the " key and the selection gets surrounded by quotes. The same thing happens with other balanced characters like (, {, [ and '. Am I missing something obvious in Emacs configuration that would enable similar behaviour when using transient mark mode, or do I need to break out elisp and write something?

  • Scalable Database Tagging Schema

    - by Longpoke
    EDIT: To people building tagging systems. Don't read this. It is not what you are looking for. I asked this when I wasn't aware that RDBMS all have their own optimization methods, just use a simple many to many scheme. I have a posting system that has millions of posts. Each post can have an infinite number of tags associated with it. Users can create tags which have notes, date created, owner, etc. A tag is almost like a post itself, because people can post notes about the tag. Each tag association has an owner and date, so we can see who added the tag and when. My question is how can I implement this? It has to be fast searching posts by tag, or tags by post. Also, users can add tags to posts by typing the name into a field, kind of like the google search bar, it has to fill in the rest of the tag name for you. I have 3 solutions at the moment, but not sure which is the best, or if there is a better way. Note that I'm not showing the layout of notes since it will be trivial once I get a proper solution for tags. Method 1. Linked list tagId in post points to a linked list in tag_assoc, the application must traverse the list until flink=0 post: id, content, ownerId, date, tagId, notesId tag_assoc: id, tagId, ownerId, flink tag: id, name, notesId Method 2. Denormalization tags is simply a VARCHAR or TEXT field containing a tab delimited array of tagId:ownerId. It cannot be a fixed size. post: id, content, ownerId, date, tags, notesId tag: id, name, notesId Method 3. Toxi (from: http://www.pui.ch/phred/archives/2005/04/tags-database-schemas.html, also same thing here: http://stackoverflow.com/questions/20856/how-do-you-recommend-implementing-tags-or-tagging) post: id, content, ownerId, date, notesId tag_assoc: ownerId, tagId, postId tag: id, name, notesId Method 3 raises the question, how fast will it be to iterate through every single row in tag_assoc? Methods 1 and 2 should be fast for returning tags by post, but for posts by tag, another lookup table must be made. The last thing I have to worry about is optimizing searching tags by name, I have not worked that out yet. I made an ASCII diagram here: http://pastebin.com/f1c4e0e53

  • Dynamic dropdown search box

    - by glebm
    Are there any gems that would help me make a search box like the one for tags on stackoverflow? (Rails 2.3.5, required IE7 support and graceful no-script fall-back) P.S.: Do these boxes annoy you or do you think it's a good thing to have one?

  • Mysql count columns

  • Poor man's "lexer" for C#

    - by Paul Hollingsworth
    I'm trying to write a very simple parser in C#. I need a lexer -- something that lets me associate regular expressions with tokens, so it reads in regexs and gives me back symbols. It seems like I ought to be able to use Regex to do the actual heavy lifting, but I can't see an easy way to do it. For one thing, Regex only seems to work on strings, not streams (why is that!?!?). Basically, I want an implementation of the following interface: interface ILexer : IDisposable { /// <summary> /// Return true if there are more tokens to read /// </summary> bool HasMoreTokens { get; } /// <summary> /// The actual contents that matched the token /// </summary> string TokenContents { get; } /// <summary> /// The particular token in "tokenDefinitions" that was matched (e.g. "STRING", "NUMBER", "OPEN PARENS", "CLOSE PARENS" /// </summary> object Token { get; } /// <summary> /// Move to the next token /// </summary> void Next(); } interface ILexerFactory { /// <summary> /// Create a Lexer for converting a stream of characters into tokens /// </summary> /// <param name="reader">TextReader that supplies the underlying stream</param> /// <param name="tokenDefinitions">A dictionary from regular expressions to their "token identifers"</param> /// <returns>The lexer</returns> ILexer CreateLexer(TextReader reader, IDictionary<string, object> tokenDefinitions); } So, pluz send the codz... No, seriously, I am about to start writing an implementation of the above interface yet I find it hard to believe that there isn't some simple way of doing this in .NET (2.0) already. So, any suggestions for a simple way to do the above? (Also, I don't want any "code generators". Performance is not important for this thing and I don't want to introduce any complexity into the build process.)

  • Is there an Emacs-analog for the VI '.' command to repeat-last-typed-text

    - by Don
    I've used emacs for decades and always wondered, but kept on coding, if there was a way to type in something, them move the cursor and insert the same text, like the VI . command. Instead what I do is to type the text, set the mark, backup, copy the region, go to the next spot (often just C-n, down one line) and then pre-arg yank, C-u C-y. It's the overhead of set mark, backup and copy region that makes me just go ahead and retype the thing.

  • How to replicate PS multiply layer mode

    - by Andrew Philpott
    Does anybody know of a good way to replicate Photoshop's multiply layer mode using either an image or CSS? I'm working on a project that has thumbnails that get a color overlay when you hover over them, but the designer used a layer set to multiply and I can't figure out how to produce it on the web. The best thing I've come up with is either using rgba or a transparent png, but even then it doesn't look right.

  • How to ANSI-C cast from unisigned int * to char *?

    - by user314290
    I want these two print functions to do the same thing: unsigned int Arraye[] = {0xffff,0xefef,65,66,67,68,69,0}; char Arrage[] = {0xffff,0xefef,65,66,67,68,69,0}; printf("%s", (char*)(2+ Arraye)); printf("%s", (char*)(2+ Arrage)); where Array is an unsigned int. Normally, I would change the type but, the problem is that most of the array is numbers, although the particular section should be printed as ASCII.

  • Finding a simple object in a low-quality image

    - by Ramon Snir
    Hi, I want to do this thing in C# (or any other .NET language), not sure how: I have an image I captured from webcam and I want to find a specific simple object in it (let's say a red circle with a black square in it). The red circle can be a bit different from time to time (because of shadows) and the square might be also a bit brighter sometimes and even rotated a bit. Please help me!

  • What can map database tables like LINQ to SQL did?

    - by trnTash
    A good thing in LINQ to SQL was a fast and reliable way to map database tables and convert them into classes accessible from c# project. However it is no longer recommended to create projects using LINQ to SQL. What is its substitute? What kind of tool should I use in VS 2010 today if I want to have the same functionality as I had with LINQ to SQL?

  • PHPUnit not working with netbeans 7.2.1

    - by user1578653
    I have just upgraded to netbeans 7.2.1 and phpunit is not working. I get the error:- Cannot run program C:\wamp\bin\php\php5.3.5\PEAR\phpunit-skelgen": CreateProcess error=193, %1 is not a valid Win32 application" when I try to generate PHPUnit tests. The only thing I can think of is that I seem to have a 64 bit version of netbeans installed - could this be the problem? If so, can anyone point me to a 32 bit version, because I couldn't see one on the website?

  • iphone: unrecognized selector sent to instance

    - by eshalev
    I am new to objective C, So maybe there is some basic thing that I am missing about selectors. I would like to understand the basic concept behind this error as I have not found an general error reference. I am getting this error when using: [CloseButton addTarget:PageContents action:@selector(CloseButtonPressed) forControlEvents:UIControlEventTouchUpInside]; and then later: - (void)CloseButtonPressed:(id)sender{ UIAlertView *someError = [[UIAlertView alloc] initWithTitle: @"Comment" message: @"hello" delegate: self cancelButtonTitle: @"Ok" otherButtonTitles: nil]; [someError show]; [someError release]; }

  • Control statements in Haskell?

    - by Nathan
    I am just beginning Haskell, but from all the online tutorials I've found I can't seem to find if there is one accepted way to do a conditional control statement. I have seen if-else, guards, and pattern matching, but they all seem to accomplish the same thing. Is there one generally accepted/faster/more efficient way than the rest?

    - by Xinxua
    I have an application which runs another application (mine) using the WinAPI "ShellExecuteEx" with the verb "RunAs" so that the other application should start with "Administrator" credentials. My OS is Windows XP. (Do not bother about other operating system, as I have specific code in place) The only problem with this thing is that the "Current User" comes preselected. I want it to be the "Following User" with Administrator selected. How to do this?
