  • jQuery dialog width resizing problem

    - by ktMen
    I try to load some HTML code into a jQueryUI dialog by AJAX. The code itself is a list, where rightmost elements should be absolutely positioned so that the list looks like a table with two columns, but only in some rows. The problem is that jQueryUI plugin does not seem to be correctly resizing the dialog's width, which I think is due to the absolute positioning of some li's. I have read some answers to other similar questions, but none helped me out with this. This is the code I load: <style type="text/css"> ul {list-style-type:none;margin:0px;padding:0px;} ul ul {margin:0px;padding:0px;} ul>li.fila {margin-bottom:5px;padding-bottom:5px;} ul li.fila ul li { display:inline; padding-left:20px; position:relative; margin-bottom:10px; } ul li.fila ul li.O { background:url(bullet.gif) 5px 8px no-repeat; list-style-position:inside; } </style> <ul id="raiz" > <li class="fila"> <ul > <li style="position:absolute;left:0px;" class="O"> <label for="col1">Col1:</label> <input type="text" name="col1" id="col1" value="vCol1" class="text ui-widget-content ui-corner-all" /> </li> <li style="left:250px;" class="O" > <label for="col2">Col2:</label> <input type="text" name="col2" id="col2" value="vCol2" class="text ui-widget-content ui-corner-all" /> </li> </ul> </li> <li class="fila"> <ul > <li> <label for="col3">Col3:</label> <input type="text" name="col3" id="col3" value="vCol3" class="text ui-widget-content ui-corner-all" /> </li> </ul> </li> </ul> And the Dialog constructor: $("#dialog").dialog({ bgiframe: true, autoOpen: false, height: 'auto', width: 'auto', modal: true, buttons:{ 'Cancel': function() { $(this).dialog('close'); } }, open: function(event,ui){ $("#dialog").load("dialogCode.html"); } }); Thanks in advance for any suggestions.

  • Any way to speed up this hierarchical query?

    - by RenderIn
    I've got a serious performance problem with a hierarchical query that I can't seem to fix. I am modeling several organization charts in my database, each representing a virtual organization within our company. For example, we have several temporary committees that are created from time to time and there may be a Committee Organizer role at the top of this virtual hierarchy, with several people assigned to the Committee Member role beneath the organizer. Some of our virtual organizations have many levels and several branches at each level. I have a single table in which I represent all the role assignments. i.e. a ROLE_ID column and a PARENT_ROLE_ID column which is a foreign key to the ROLE_ID column. For each assignment we also store as a column the location in the company where this person has the assignment. For example, the Committee Organizer would have a company-level/ CEO assignment, while the committee members would have department-level assignments such as ACCOUNTING, MARKETING, etc. So to model the organizer/member relationship for two individuals we would have: ROLE_ID = 4 PARENT_ROLE_ID = NULL EMPLOYEE_NUMBER = 213423 COMPANY_LOCATION = CEO ROLE_ID = 5 PARENT_ROLE_ID = 4 EMPLOYEE_NUMBER = 838221 COMPANY_LOCATION = ACCOUNTING Here's where things get tricky. I have an application that every person in the organization can log in to. When they log in they should be able to view all the virtual organizations in our company. e.g. the committee members should be able to see the committee organizer and vice-versa. However, only the committee organizer should be able to edit the committee members. The difficulty is in determining whether an individual (who can have multiple role assignments) has edit access for each other assignment. While this seems simple in the example, consider a virtual organization in which we have President at the top, 5 departments directly beneath him, 2 subdepartments below each department. We only want people in the Accounting department to be able to edit individuals in the subdepartments belonging to the Accounting department. They should not have edit access to anybody in the Marketing department or its subdepartments. To determine edit access when a user views a virtual organization in our company I run a query that executes two inline views: A) Hierarchically query for all assignments in this virtual organization and using SYS_CONNECT_BY_PATH to store the entire path to each user/role/company_location and B) Hierarchically retrieve all the assignments the individual logged in has and using the SYS_CONNECT_BY_PATH to store the entire path to each of these assignments. The result of the query is all the records from A) plus a boolean determined by joining with B) which flags whether the logged in user has edit access for each record. Indexes don't seem to be helping... it simply appears that there is too much processing going on to separate all the records and then determine edit access. One issue is that I can't store the SYS_CONNECT_BY_PATH and index it... determining whether an individual record has edit access consists of comparing if: test_record_sys_path LIKE individual_record_sys_path || '%' Is a materialized view the answer?

  • How are you using IronPython?

    - by Will Dean
    I'm keen to drink some modern dynamic language koolaid, so I've believed all the stuff on Michael Foord's blog and podcasts, I've bought his book (and read some of it), and I added an embedded IPy runtime to a large existing app a year or so ago (though that was for someone else and I didn't really use it myself). Now I need to do some fairly simple code generation stuff, where I'm going to call a few methods on a few .net objects (custom, C#-authored objects), create a few strings, write some files, etc. The experience of trying this leaves me feeling like the little boy who thinks he's the only one who can see that The Emperor has no clothes on. If you're using IronPython, I'd really appreciate knowing how you deal with the following aspects of it: Code editing - do you use the .NET framework without Intellisense? Refactoring - I know a load of 'refactoring' is about working around language-related busywork, so if Python is sufficiently lightweight then we won't need that, But things like renames seem to me to be essential to iteratively developing quality code regardless of language. Crippling startup time - One of the things which is supposed to be good about interpreted languages is the lack of compile time leading to fast interactive development. Unfortunately I can compile a C# application and launch it quicker than IPy can start up. Interactive hacking - the IPy console/repl is supposed to be good for this, but I haven't found a good way to take the code you've interactively arrived at and persist it into a file - cut and paste from the console is fairly miserable. And the console seems to hold references to .NET assemblies you've imported, so you have to quit it and restart it if you're working on the C# stuff as well. Hacking on C# in something like LinqPad seems a much faster and easier way to try things out (and has proper Intellisense). Do you use the console? Debugging - what's the story here? I know someone on the IPy team is working on a command-line hobby-project, but let's just say I'm not immediately attracted to a command line debugger. I don't really need a debugger from little Python scripts, but I would if I were to use IPy for scripting unit tests, for example. Unit testing - I can see that dynamic languages could be great for this, but is there any IDE test-runner integration (like for Resharper, etc). The Foord book has a chapter about this, which I'll admit I have not yet read properly, but it does seem to involve driving a console-mode test-runner from the command prompt, which feels to be an enormous step back from using an integrated test runner like TestDriven.net or Resharper. I really want to believe in this stuff, so I am still working on the assumption that I've missed something. I would really like to know how other people are dealing with IPy, particularly if they're doing it in a way which doesn't feel like we've just lost 15 years'-worth of tool development.

  • overloading friend operator<< for template class

    - by starcorn
    Hello, I have read couple of the question regarding my problem on stackoverflow now, and none of it seems to solve my problem. Or I maybe have done it wrong... The overloaded << if I make it into an inline function. But how do I make it work in my case? warning: friend declaration std::ostream& operator<<(std::ostream&, const D<classT>&)' declares a non-template function warning: (if this is not what you intended, make sure the function template has already been declared and add <> after the function name here) -Wno-non-template-friend disables this warning /tmp/cc6VTWdv.o:uppgift4.cc:(.text+0x180): undefined reference to operator<<(std::basic_ostream<char, std::char_traits<char> >&, D<int> const&)' collect2: ld returned 1 exit status template <class T> T my_max(T a, T b) { if(a > b) return a; else return b; } template <class classT> class D { public: D(classT in) : d(in) {}; bool operator>(const D& rhs) const; classT operator=(const D<classT>& rhs); friend ostream& operator<< (ostream & os, const D<classT>& rhs); private: classT d; }; int main() { int i1 = 1; int i2 = 2; D<int> d1(i1); D<int> d2(i2); cout << my_max(d1,d2) << endl; return 0; } template <class classT> ostream& operator<<(ostream &os, const D<classT>& rhs) { os << rhs.d; return os; }

  • Entity Framework Update Entity along with child entities (add/update as necessary)

    - by Jorin
    I have a many-to-many relationship between Issues and Scopes in my EF Context. In ASP.NET MVC, I bring up an Edit form that allows the user to edit a particular Issue. At the bottom of the form, is a list of checkboxes that allow them to select which scopes apply to this issue. When editing an issue, it likely will always have some Scopes associated with it already--these boxes will be checked already. However, the user has the opportunity to check more scopes or remove some of the currently checked scopes. My code looked something like this to save just the Issue: using (var edmx = new MayflyEntities()) { Issue issue = new Issue { IssueID = id, TSColumn = formIssue.TSColumn }; edmx.Issues.Attach(issue); UpdateModel(issue); if (ModelState.IsValid) { //if (edmx.SaveChanges() != 1) throw new Exception("Unknown error. Please try again."); edmx.SaveChanges(); TempData["message"] = string.Format("Issue #{0} successfully modified.", id); } } So, when I try to add in the logic to save the associated scopes, I tried several things, but ultimately, this is what made the most sense to me: using (var edmx = new MayflyEntities()) { Issue issue = new Issue { IssueID = id, TSColumn = formIssue.TSColumn }; edmx.Issues.Attach(issue); UpdateModel(issue); foreach (int scopeID in formIssue.ScopeIDs) { var thisScope = new Scope { ID = scopeID }; edmx.Scopes.Attach(thisScope); thisScope.ProjectID = formIssue.ProjectID; if (issue.Scopes.Contains(thisScope)) { issue.Scopes.Attach(thisScope); //the scope already exists } else { issue.Scopes.Add(thisScope); // the scope needs to be added } } if (ModelState.IsValid) { //if (edmx.SaveChanges() != 1) throw new Exception("Unknown error. Please try again."); edmx.SaveChanges(); TempData["message"] = string.Format("Issue #{0} successfully modified.", id); } } But, unfortunately, that just throws the following exception: An object with the same key already exists in the ObjectStateManager. The ObjectStateManager cannot track multiple objects with the same key. What am I doing wrong?

  • Why does SFINAE not apply to this?

    - by Simon Buchan
    I'm writing some simple point code while trying out Visual Studio 10 (Beta 2), and I've hit this code where I would expect SFINAE to kick in, but it seems not to: template<typename T> struct point { T x, y; point(T x, T y) : x(x), y(y) {} }; template<typename T, typename U> struct op_div { typedef decltype(T() / U()) type; }; template<typename T, typename U> point<typename op_div<T, U>::type> operator/(point<T> const& l, point<U> const& r) { return point<typename op_div<T, U>::type>(l.x / r.x, l.y / r.y); } template<typename T, typename U> point<typename op_div<T, U>::type> operator/(point<T> const& l, U const& r) { return point<typename op_div<T, U>::type>(l.x / r, l.y / r); } int main() { point<int>(0, 1) / point<float>(2, 3); } This gives error C2512: 'point<T>::point' : no appropriate default constructor available Given that it is a beta, I did a quick sanity check with the online comeau compiler, and it agrees with an identical error, so it seems this behavior is correct, but I can't see why. In this case some workarounds are to simply inline the decltype(T() / U()), to give the point class a default constructor, or to use decltype on the full result expression, but I got this error while trying to simplify an error I was getting with a version of op_div that did not require a default constructor*, so I would rather fix my understanding of C++ rather than to just do what works. Thanks! *: the original: template<typename T, typename U> struct op_div { static T t(); static U u(); typedef decltype(t() / u()) type; }; Which gives error C2784: 'point<op_div<T,U>::type> operator /(const point<T> &,const U &)' : could not deduce template argument for 'const point<T> &' from 'int', and also for the point<T> / point<U> overload.

  • How can I capture the keystroke that triggers "CellEndEdit" on a DataGridView in C#?

    - by Andy Stampor
    I have a DataGridView that is set to EditOnF2. I do some special processing of data in the CellEndEdit eventhandler that sets the value of the cell. I still want the functionality of the EditOnKeystrokeOrF2 of reverting to the original value when the Esc key is pressed. Unfortunately, at the CellEndEdit eventhandler, I don't see a way to tell what caused the CellEndEdit event to be fired. I only want to change the value of the cell if the Esc key is not pressed. How can I tell if it was or not? Edit: It is worth noting that the KeyDown event does not get fired when the cell is being edited, nor for the final ending keystroke. Edit2: I have tried the KeyPreview suggestion, but the form still does not capture the Escape key being pressed. Edit3: I've been experimenting with trying to get this working. I originally posted some of the following as a separate post, but feel it might be more relevant to include it here. I have a cell in a DataGridView that is now set to EditProgrammatically. To capture the keystroke that starts an edit, I am setting the cell.Value equal to the keystroke. However, this ruins the "Escape" functionality of the cell - when you press escape, instead of reverting to the original value, it reverts to the keystroke that I programmatically inserted into the cell. I believe that if I could set the "EditedFormattedValue" on a cell, this would be where I want to put my keystroke value, however this appears to be read only. How can I accomplish what I am attempting? An example to clarify: If the cell has a value of "54.3" in it, and I press the "9" key, it begins editing the cell and places a "9" there. If I hit Escape, instead of reverting to "54.3" it reverts to "9". What I want is for it to return to its original value of "54.3". So, I am trying to tackle this issue from both the beginning and the end. I think the real problem is that I am overwriting the original value and have no way to determine if I should revert it or not. Edit4: It looks like CellValidating might be worth using, but I am seeing strange behavior when I experiment with it. In a new project, I create the DataGridView and register for the various events and see that CellValidating is fired before the CellEndEdit. However, in my project where I am trying to get this to work, CellEndEdit is firing BEFORE CellValidating. Any ideas on what the difference might be?

  • JavaScript Resource Management Design Pattern

    - by Adam
    As a web developer, a common problem I find myself tackling is waiting for something to load before doing something else. In particular, I often hide (using either display: none; or visibility: hidden; depending on the situation) elements while waiting for a background image or a CSS file to load. Consider this example from Last.FM. They overlay a semi-transparant PNG over each album art image so that it looks like it's inside a jewel-case. They let it load when it loads, so depending on your internet speed, you may see the art image by itself (without the overlay) temporarily. In this case, the album art looks fine without the jewel-case effect. But in similar situations, I have found that I don't want the user to see the site's design mangled as resources incrementally load. So, in rare cases I have hidden everything from the user until the whole kit and kaboodle has loaded. But this is often a pain to write out, and may force the user to wait for a pretty long time to see anything (besides "loading..." text). I can think of (and have used on occasion) some obvious solutions/compromises: Use some inline CSS so that as certain parts of the DOM load and render, they will immediately have the correct size/position/etc. Immediately render the navigation part of the site, so that if the user wanted to use the current page purely to get somewhere else, they don't have to wait for the rest to load. Load pixelated images first as placeholders for layout while lazy-loading higher quality images as replacements. Something quirky like using a cute animated gif to distract the user during a "loading..." phase. Show useful information as a reference while loading the full UI. (Something akin to Gmail Inbox Preview, etc.) (Sorry if my question was basically just asked and answered...) Despite all of these ideas, I still find myself hoping there are better ways of doing some of these things. So I guess what I'm looking for is some inspiration and/or any creative ways of dealing with this problem that you guys may have seen out in the wild.

  • Which MarkDown (WMD) javascript editor should I use?

    - by Edan Maor
    Background I'm working on an application which requires user-entered content, and I've decided to use a StackOverflow-style MarkDown editor. After researching this topic for the last few days, I realize there are numerous forks of the base WMD editor, some with a few basic enhancements and some with serious differences from the StackOverflow one. Since this will be the heart of the application, I'd like to start with the best code base I can. I'd be happy if anyone can recommend which one of the many solutions out there best fits my needs. Below is requirements, plus what I've managed to find already. I'm hoping this question will help me decide which version to go with, and maybe help me discover a port out there that's an even better fit for my needs. The requirements for my project Live Preview Multiple editors on the same page (not know how many in advance, since the user can dynamically add another editing box). Ability to extend with extra buttons (I'd like a button to upload a picture, instead of just adding an img url). Ability to dynamically show/hide the edit box (and only see the preview box). Not an absolute must, but I'd prefer to stick as close to StackOverflow's look and feel, since it's well known. Don't know if this matters, but the backend is written in Django. Editors I've looked at Here are a few of the code bases I've looked at, with thoughts. Obviously, I might be missing another solution out there. The derobins version. From what I can tell, this is the official StackOverflow version. Seems like it doesn't support multiple editors on one page. JQuery.MarkEdit. Looks very good, but is pretty different from the StackOverflow version. MooWMD. Looks like the winner right now, but I'm a little concerned since it looks less active/hackable than MarkEdit. The wmd-new version. Not sure, looks like an old codebase without much use. The SocialSite branch. Seems like it's not for public use.

  • Help making this code run faster for spoj.

    hy, i have a little, big problem here :) after i upload some images i get a list with all the images. I have some jQuery function for rotate, duplicate, delete, shuffle images! when i select a image and hit delete i send a post to php with the alt="" value of the image,i identify the picture and edit. I want to make a save button, Instead of sending a post every time i rotate a image, better send a post after editing the list of images with an array that contains all data? my php array after upload looks like this: [files] => Array ( [lcxkijgr] => lcxkijgr.jpg [xcewxpfv] => xcewxpfv.jpg [rtiurwxf] => rtiurwxf.jpg [gsbxdsdc] => gsbxdsdc.jpg ) say that I uploaded 4 pictures, firs picture i rotate 90 degrees second i want to duplicate third i rotate 270 degrees and the fourth image i delete i can do all this only with jQuery, but on the server the images are the same, after a refresh the images are the same this is the list with the images: <div class="upimage"> <ul id="upimagesQueue"> <li id="upimagesHPVEJM"> <a href="javascript:jQuery('#upimagesHPVEJM').showlargeimage('HPVEJM')"> <img alt="lcxkijgr" src="uploads/s6id9r9icnp8q9102h8md9kfd7/lcxkijgr.jpg?1272087830477" id="HPVEJM" style="display: block;" > </a> </li> <li id="upimagesSTCSAV"> <a href="javascript:jQuery('#upimagesSTCSAV').showlargeimage('STCSAV')"> <img alt="xcewxpfv" src="uploads/s6id9r9icnp8q9102h8md9kfd7/xcewxpfv.jpg?1272087831360" id="STCSAV" style="display: block;" > </a> </li> <li id="upimagesBFPUEQ"> <a href="javascript:jQuery('#upimagesBFPUEQ').showlargeimage('BFPUEQ')"> <img alt="rtiurwxf" src="uploads/s6id9r9icnp8q9102h8md9kfd7/rtiurwxf.jpg?1272087832162" id="BFPUEQ" style="display: block;" > </a> </li> <li id="upimagesRKXNSV"> <a href="javascript:jQuery('#upimagesRKXNSV').showlargeimage('RKXNSV')"> <img alt="gsbxdsdc" src="uploads/s6id9r9icnp8q9102h8md9kfd7/gsbxdsdc.jpg?1272087832957" id="RKXNSV" style="display: block;"> </a> </li> <ul> </div> is ok if i make one array like this: array{ imgFromLi = array(img1,img2,img3,img4,img5,img6) rotate = array{img1=90, img2=270, img3=90} delete = array{img4,img5,img6} duplicate = array{img2, img3} } how i can send/cache this array?? sorry for my very bad english

  • Question SpeechSynthesizer.SetOutputToAudioStream audio format problem

    - by Chris Kugler
    Hi, I'm currently working on an application which requires transmission of speech encoded to a specific audio format. System.Speech.AudioFormat.SpeechAudioFormatInfo synthFormat = new System.Speech.AudioFormat.SpeechAudioFormatInfo(System.Speech.AudioFormat.EncodingFormat.Pcm, 8000, 16, 1, 16000, 2, null); This states that the audio is in PCM format, 8000 samples per second, 16 bits per sample, mono, 16000 average bytes per second, block alignment of 2. When I attempt to execute the following code there is nothing written to my MemoryStream instance; however when I change from 8000 samples per second up to 11025 the audio data is written successfully. SpeechSynthesizer synthesizer = new SpeechSynthesizer(); waveStream = new MemoryStream(); PromptBuilder pbuilder = new PromptBuilder(); PromptStyle pStyle = new PromptStyle(); pStyle.Emphasis = PromptEmphasis.None; pStyle.Rate = PromptRate.Fast; pStyle.Volume = PromptVolume.ExtraLoud; pbuilder.StartStyle(pStyle); pbuilder.StartParagraph(); pbuilder.StartVoice(VoiceGender.Male, VoiceAge.Teen, 2); pbuilder.StartSentence(); pbuilder.AppendText("This is some text."); pbuilder.EndSentence(); pbuilder.EndVoice(); pbuilder.EndParagraph(); pbuilder.EndStyle(); synthesizer.SetOutputToAudioStream(waveStream, synthFormat); synthesizer.Speak(pbuilder); synthesizer.SetOutputToNull(); There are no exceptions or errors recorded when using a sample rate of 8000 and I couldn't find anything useful in the documentation regarding SetOutputToAudioStream and why it succeeds at 11025 samples per second and not 8000. I have a workaround involving a wav file that I generated and converted to the correct sample rate using some sound editing tools, but I would like to generate the audio from within the application if I can. One particular point of interest was that the SpeechRecognitionEngine accepts that audio format and successfully recognized the speech in my synthesized wave file... Update: Recently discovered that this audio format succeeds for certain installed voices, but fails for others. It fails specifically for LH Michael and LH Michelle, and failure varies for certain voice settings defined in the PromptBuilder.

  • Issue while trying to give a floating effect to a footer bar in IE

    - by Shailesh
    Hi, I'm trying to put a footer bar at the bottom of the browser no matter what the length of the content is. The footer bar should always be visible to the user and should be on the top layer. Following is my code: <html> <head> <style type="text/css"> #wrapper { width: 910px; margin: 0 auto; padding: 0px 20px 50px 20px; text-align: left; } #footer-wrapper { -moz-background-clip:border; -moz-background-inline-policy:continuous; -moz-background-origin:padding; bottom:0; clear:both; font-size:11px !important; left:0; position:fixed; white-space:nowrap; width:100%; z-index:8000; } </style> <script> var counter = 0; function addContent(ctr) { document.getElementById(ctr).innerHTML=document.getElementById (ctr).innerHTML+" dynaContent"+counter; counter++; } </script> </head> <body> <div> <div><input type="button" onclick="addContent('wrapper')" value="Add dynaContent" /></div> <div id="wrapper" style="color:#FFFFFF; background-color: #111111;"> STATIC TEXT - HEADER-WRAPPER </div> <div style="color:#FFFFFF;background-color: #555555;">STATIC TEXT - FOOTER-WRAPPER</div> </div> </body> </html> It's working fine in Mozilla Firefox and giving the intended results, but, in IE, the footer bar always sticks just under the header. Please help. Thanks in advance, Shailesh.

  • Stop images from wrapping when div width is to small.

    - by razass
    I have a div that contains a ul and in each li there is a picture. I have floated the pictures left to get them to line up in a straight line however once it reaches the end of the div, it wraps. I would like the pictures to continue on to the right, hidden, so that I am able to create a carousel. My code is below. The HTML <div id="container"> <div class="lfbtn"></div> <ul id="image_container"> <li class="the_image"> <img src="" /> </li> </ul> <div class="rtbtn"></div> </div> The CSS #container { width: 900px; height: 150px; margin: 10px auto; } #image_container { position: relative; left: 50px; list-style-type: none; width: 700px; height: 110px; overflow: hidden; } #image_container li { display: inline-block; padding: 7px 5px 7px 5px; float: left; } .lfbtn { background-image: url(../../img/left.gif); background-repeat: no-repeat; margin: 10px; position: relative; float: left; top: -12px; left: 50px; height: 90px; width: 25px; } .rtbtn { background-image: url(../../img/right.gif); background-repeat: no-repeat; height: 90px; width: 25px; margin: 10px; position: relative; top: -101px; left: 795px; } Thanks in advance!

    This is my html code : <div id="tabbase"> <ul> <li>a</li> <li>b</li> </ul> <div id="tabs-0"></div> <div id="tabs-1"> <div class="width50"> <h5>title1</h5> <div class="da-desc">a</div> <button>continue</button> </div> <div class="width50"> <h5>title2</h5> <div class="da-desc">b</div> <button>continue</button> </div> </div> </div> and this is CSS code : #tabbase { margin:16px; } #tabbase ul li { display:inline-block; margin:5px 0px 5px 0; background:rgb(224,224,224); padding:5px; border:1px solid rgb(153,153,153); cursor:pointer; } #tabs-0, #tabs-1 { border:1px solid rgb(153,153,153); background:rgb(255,255,255); padding:5px; margin:-5px 0 0 0; } #tabbase ul li.active { background:rgb(255,255,255) !important; } and this is jquery code : $(document).ready(function(e) { $("#tabs-1").hide(0); $("#tabbase ul li:first").addClass("active"); $("#tabbase ul li").click(function(e) { $(this).addClass("active"); $(this).siblings(this).removeClass("active"); count = $("#tabbase ul li").index(this); $('#tabs-'+count).slideDown(500).siblings(this).slideUp(500); }); }); so you can see that when you click on a tab , all tabs are gone and how can I fix this?

  • Adding a mini admin to a webpage.

    - by DADU
    Hello Picture this: you are creating a little module that people can incorporate into their website easily, for example, a little contact form. It would consist of a PHP file that outputs some HTML, a Javascript file (ajax etc.), a CSS file and a CSS skin. Now the person who doesn't know much about coding wants to integrate it on a webpage (website/index.php). We could do this with three rules of code: <link rel="stylesheet" href="module/css/module.css" /> <script src="module/js/module.js"></script> <?php require_once 'module/module.php'; ?> There's no doubt this part is questionable, right? Now when we want to add an admin for this little module, there are two options: Accessing the admin via an extra URL like website/module/admin.php and after authentication, displaying a page where the person can do all the settings. The person then goes back to index.php to see the results. Enabling the admin via an extra URL like website/module/admin.php and after authentication, redirecting back to index.php. The person can now edit the module directly (HTML5 contenteditable) and see changes live, on the webpage where everybody else will see it when the person saves the changes. Option 2 has a couple of advantages: The person doesn't have to toggle between admin and index.php. The person can see directly how it's looking at the webpage it's integrated in. The person probably feels like the module is more part of the webpage/website. Of course option 2 has some disadvantages too: Not everything works well editing it inline. The person would need to have an HTML5 compliant browser. Probably some more I can't think of right now. Now I have a few concerns that's I can't seem to see a clear answer to. How would we let the person integrate the admin on their webpage? The admin files only need to be included in index.php if the person has choosen to edit the module via the url (website/module/admin.php). But how can we do this if we have a admin.css file that belongs in the head section, an admin.php file that goes into the body, and another admin.js file that's included at the end of the body? How would we know the file that admin.php needs to redirect back to, after authentication? index.php could be any webpage with any name. Any real life website/web apps examples using this principle are welcome too. If there's something unclear, I am glad to add additional info.

  • adding a class when link is clicked from Wordpress loop

    - by Carey Estes
    I am trying to isolate and add a class to a clicked anchor tag. The tags are getting pulled from a Wordpress loop. I can write JQuery to remove the "static" class, but it is removing the class from all tags in the div rather than just the one clicked and not adding the "active" class. Here is the WP loop <div class="more"> <a class="static" href="<?php bloginfo('template_url'); ?>/work/">ALL</a> <?php foreach ($tax_terms as $tax_term) { echo '<a class="static" href="' . esc_attr(get_term_link($tax_term, $taxonomy)) . '" title="' . sprintf( __( "View all posts in %s" ), $tax_term->name ) . '" ' . '>' . $tax_term->name.'</a>'; } ?> </div> Generates this html: <div class="more"> <a class="static" href="#">ALL</a> <a class="static" href="#">Things</a> <a class="static" href="#"> More Things</a> <a class="static" href="#">Objects</a> <a class="static" href="#">Goals</a> <a class="static" href="#">Books</a> <a class="static" href="#">Drawings</a> <a class="static" href="#">Thoughts</a> </div> JQuery: $("div.more a").on("click", function () { $("a.static").removeClass("static"); $(this).addClass("active"); }); I have reviwed the other similar questions here and here, but neither solution is working for me. Can this be done with JQuery or should I put a click event in the html inline anchor? It looks like it is working just for a second until the page reloads.

  • WPF performance for large number of elements on the screen

    - by Mark
    Im currently trying to create a Scene in WPF where I have around 250 controls on my screen and the user can Pan and Zoom in and out of these controls using the mouse. I have run the WPF Performance Suite tools on the application when there are a large number of these controls on the screen (i.e. when the user has zoomed right out) the FPS drops down to around 15 which is not very good. Here is the basic outline of the XAML: <Window> <Window.Resources> <ControlTemplate x:Key="LandTemplate" TargetType="{x:Type local:LandControl}"> <Canvas> <Path Fill="White" Stretch="Fill" Stroke="Black" StrokeThickness="1" Width="55.5" Height="74.687" Data="M0.5,0.5 L55,0.5 L55,74.187 L0.5,74.187 z"/> <Canvas x:Name="DetailLevelCanvas" Width="24.5" Height="21" Canvas.Left="15.306" Canvas.Top="23.972"> <TextBlock Width="21" Height="14" Text="712" TextWrapping="Wrap" Foreground="Black"/> <TextBlock Width="17.5" Height="7" Canvas.Left="7" Canvas.Top="14" Text="614m2" TextWrapping="Wrap" FontSize="5.333" Foreground="Black"/> </Canvas> </Canvas> </ControlTemplate> </Window.Resources> ... <local:LandControl Width="55.5" Height="74.552" Canvas.Top="xxx" Template=" {StaticResource LandTemplate}" RenderTransformOrigin="0.5,0.5" Canvas.Left="xxx"> <local:LandControl Width="55.5" Height="74.552" Canvas.Top="xxx" Template=" {StaticResource LandTemplate}" RenderTransformOrigin="0.5,0.5" Canvas.Left="xxx"> <local:LandControl Width="55.5" Height="74.552" Canvas.Top="xxx" Template=" {StaticResource LandTemplate}" RenderTransformOrigin="0.5,0.5" Canvas.Left="xxx"> <local:LandControl Width="55.5" Height="74.552" Canvas.Top="xxx" Template=" {StaticResource LandTemplate}" RenderTransformOrigin="0.5,0.5" Canvas.Left="xxx"> ... and so on... </Window> Ive tried to minimise the details in the control template and I even did a massive find and replace of the controls to just put their raw elements inline instead of using a template, but with no noticeable performance improvements. I have seen other SO questions about this and people say to do custom drawing, but I dont really see how that make sense when you have to zoom and pan like I do. If anyone can help out here, that would be great! Mark

  • QValidator for hex input

    - by Evan Teran
    I have a Qt widget which should only accept a hex string as input. It is very simple to restrict the input characters to [0-9A-Fa-f], but I would like to have it display with a delimiter between "bytes" so for example if the delimiter is a space, and the user types 0011223344 I would like the line edit to display 00 11 22 33 44 Now if the user presses the backspace key 3 times, then I want it to display 00 11 22 3. I almost have what i want, so far there is only one subtle bug involving using the delete key to remove a delimiter. Does anyone have a better way to implement this validator? Here's my code so far: class HexStringValidator : public QValidator { public: HexStringValidator(QObject * parent) : QValidator(parent) {} public: virtual void fixup(QString &input) const { QString temp; int index = 0; // every 2 digits insert a space if they didn't explicitly type one Q_FOREACH(QChar ch, input) { if(std::isxdigit(ch.toAscii())) { if(index != 0 && (index & 1) == 0) { temp += ' '; } temp += ch.toUpper(); ++index; } } input = temp; } virtual State validate(QString &input, int &pos) const { if(!input.isEmpty()) { // TODO: can we detect if the char which was JUST deleted // (if any was deleted) was a space? and special case this? // as to not have the bug in this case? const int char_pos = pos - input.left(pos).count(' '); int chars = 0; fixup(input); pos = 0; while(chars != char_pos) { if(input[pos] != ' ') { ++chars; } ++pos; } // favor the right side of a space if(input[pos] == ' ') { ++pos; } } return QValidator::Acceptable; } }; For now this code is functional enough, but I'd love to have it work 100% as expected. Obviously the ideal would be the just separate the display of the hex string from the actual characters stored in the QLineEdit's internal buffer but I have no idea where to start with that and I imagine is a non-trivial undertaking. In essence, I would like to have a Validator which conforms to this regex: "[0-9A-Fa-f]( [0-9A-Fa-f])*" but I don't want the user to ever have to type a space as delimiter. Likewise, when editing what they types, the spaces should be managed implicitly.

  • How can I have a Makefile automatically rebuild source files that include a modified header file? (I

    - by Nicholas Flynt
    I have the following makefile that I use to build a program (a kernel, actually) that I'm working on. Its from scratch and I'm learning about the process, so its not perfect, but I think its powerful enough at this point for my level of experience writing makefiles. AS = nasm CC = gcc LD = ld TARGET = core BUILD = build SOURCES = source INCLUDE = include ASM = assembly VPATH = $(SOURCES) CFLAGS = -Wall -O -fstrength-reduce -fomit-frame-pointer -finline-functions \ -nostdinc -fno-builtin -I $(INCLUDE) ASFLAGS = -f elf #CFILES = core.c consoleio.c system.c CFILES = $(foreach dir,$(SOURCES),$(notdir $(wildcard $(dir)/*.c))) SFILES = assembly/start.asm SOBJS = $(SFILES:.asm=.o) COBJS = $(CFILES:.c=.o) OBJS = $(SOBJS) $(COBJS) build : $(TARGET).img $(TARGET).img : $(TARGET).elf c:/python26/python.exe concat.py stage1 stage2 pad.bin core.elf floppy.img $(TARGET).elf : $(OBJS) $(LD) -T link.ld -o $@ $^ $(SOBJS) : $(SFILES) $(AS) $(ASFLAGS) $< -o $@ %.o: %.c @echo Compiling $<... $(CC) $(CFLAGS) -c -o $@ $< #Clean Script - Should clear out all .o files everywhere and all that. clean: -del *.img -del *.o -del assembly\*.o -del core.elf My main issue with this makefile is that when I modify a header file that one or more C files include, the C files aren't rebuilt. I can fix this quite easily by having all of my header files be dependencies for all of my C files, but that would effectively cause a complete rebuild of the project any time I changed/added a header file, which would not be very graceful. What I want is for only the C files that include the header file I change to be rebuilt, and for the entire project to be linked again. I can do the linking by causing all header files to be dependencies of the target, but I cannot figure out how to make the C files be invalidated when their included header files are newer. I've heard that GCC has some commands to make this possible (so the makefile can somehow figure out which files need to be rebuilt) but I can't for the life of me find an actual implementation example to look at. Can someone post a solution that will enable this behavior in a makefile? EDIT: I should clarify, I'm familiar with the concept of putting the individual targets in and having each target.o require the header files. That requires me to be editing the makefile every time I include a header file somewhere, which is a bit of a pain. I'm looking for a solution that can derive the header file dependencies on its own, which I'm fairly certain I've seen in other projects.

  • Unique_ptr compiler errors

    - by Godric Seer
    I am designing and entity-component system for a project, and C++ memory management is giving me a few issues. I just want to make sure my design is legitimate. So to start I have an Entity class which stores a vector of Components: class Entity { private: std::vector<std::unique_ptr<Component> > components; public: Entity() { }; void AddComponent(Component* component) { this -> components.push_back(std::unique_ptr<Component>(component)); } ~Entity(); }; Which if I am not mistaken means that when the destructor is called (even the default, compiler created one), the destructor for the Entity, will call ~components, which will call ~std::unique_ptr for each element in the vector, and lead to the destruction of each Component, which is what I want. The component class has virtual methods, but the important part is its constructor: Component::Component(Entity parent) { parent.addComponent(this) // I am not sure if this would work like I expect // Other things here } As long as passing this to the method works, this also does what I want. My confusion is in the factory. What I want to do is something along the lines of: std::shared_ptr<Entity> createEntity() { std::shared_ptr<Entity> entityPtr(new Entity()); new Component(*parent); // Initialize more, and other types of Components return entityPtr; } Now, I believe that this setup will leave the ownership of the Component in the hands of its Parent Entity, which is what I want. First a small question, do I need to pass the entity into the Component constructor by reference or pointer or something? If I understand C++, it would pass by value, which means it gets copied, and the copied entity would die at the end of the constructor. The second, and main question is that code based on this sample will not compile. The complete error is too large to print here, however I think I know somewhat of what is going on. The compiler's error says I can't delete an incomplete type. My Component class has a purely virtual destructor with an implementation: inline Component::~Component() { }; at the end of the header. However since the whole point is that Component is actually an interface. I know from here that a complete type is required for unique_ptr destruction. The question is, how do I work around this? For reference I am using gcc 4.4.6.
