  • i integer does not +1 the 1st time

    - by Hwang
    I have a gallery where it will load an image after a previous image is loaded, so every time 'i' will +1 so that it could move to the next image. This code works fine on my other files, but I dunno why it doesn't work for the current file. Normally if I trace 'i' the correct will be 0,1,2,3,4,5,6... etc adding on till the limit, but this files its 'i' repeat the 1st number twice, only it continues to add 0,0,1,2,3,4,5,6...etc The code is completely the same with the other file I'm using, but I don't know why it just doesn't work here. The code does not seems to have any problem. Anyway i can work around this situation? private var i:uint=0; private function loadItem():void { if (i<myXMLList.length()) { loadedPic=myXMLList[i].thumbnails; galleryLoader = new Loader(); galleryLoader.load(new URLRequest(loadedPic)); galleryLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,picLoaded); } else { adjustImage(); } } private function picLoaded(event:Event):void { var bmp=new Bitmap(event.target.content.bitmapData); bmp.smoothing=true; bmpArray.push(bmp); imagesArray[i].addChild(bmp); i++; loadItem(); }

  • The right approach to loading dynamic content into a UITableView in iOS

    - by OS.
    ok, I've read tons of bits and pieces on the subject of loading dynamic content (from the web) into a UITableView and the problem with calculating cell height upfront. I've tried different simple implementations but the problem persists... Assuming I need to read a JSON file from the web, parse it into 'item' objects, each with variable size image and various text labels, here is what I believe would be the right approach to avoid long hang time of the app while everything is loading: on app load read JSON file and parse into items array provide only small part of the items array to the tableview (about 10 items) - since I need to load the images associated with each item to calculate cell height - I don't want the view to go through the whole items list and load all images - this hangs the app until every image is loaded display the tableview with the available cells (assuming I load a few 'spare' ones, user can even scroll to more items) in the background using Grand Central Dispatch download images for all/some of the remaining items and then reload the tableview with the new data (repeat step 4 if item list is very long) Step 2 above is necessary since I have no way to calculate the cell height without loading the images first, and since tableview first calculates height of all cells it may take a very long time to download all images for all items. Would you say this is the right approach? am I missing something?

  • Looping the layout that was set up in Interface Builder

    - by Slavenko
    I just need for someone to point me in the right direction of how I should be doing things. I wanted to make an iOS news like app that would have interface resembling Windows Phone. Large and small image tiles that represent one news item each. Now I was thinking to create some basic layout in storyboard, that would consist out of, for example, a title, and a 3 different sized tiles/images (the gray part on the attached image). Now, I would be getting the data as a JSON array that has holds different news categories so I was wondering if somehow the set up layout could be reused in a for loop since the layout will only repeat itself (the red part on the attached image) and oly the data would be different. Can this be done, should I even try doing something like this, or should I try to create an entire layout programmatically? I wouldn't mind doing it programatically, it's just that I don't have much experience in creating layouts that way, and wanted to make sure that I don't do something that I might regret later. Thank you for any help and advice.

  • how to achieve functionality of #def of c in PHP

    - by Sabya
    Well, I don't know if thats what I want. But here is my problem: In case of some error I am logging the FILE, CLASS, FUNCTION and LINE in a file. For that I am doing something like: myLog('['. __FILE__ . ']' . '[' . __CLASS__ . ']' . '[' . __FUNCTION__ . ']' . '[' . __LINE__ . ']'); The problem is everywhere I've to repeat that code in the parameter. and If I want to change the format, I've to change everywhere. How can I have something like: myLog(LOG_MSG_FORMAT); With PHP define it is not possible since it will give my the LINE number of the place where that definition is, not where the definition is getting used. Any solution to this is welcome. I am not bitchy about having C like functionality of #def.

  • Creating and parsing huge strings with javascript?

    - by user246114
    Hi, I have a simple piece of data that I'm storing on a server, as a plain string. It is kind of ridiculous, but it looks like this: name|date|grade|description|name|date|grade|description|repeat for a long time this string can be up to 1.4mb in size. The idea is that it's a bunch of student records, just strung together with a simple pipe delimeter. It's a very poor serialization method. Once this massive string is pushed to the client, it is split along the pipes into student records again, using javascript. I've been timing how long it takes to create, and split, these strings on the client side. The times are actually quite good, the slowest run I've seen on a few different machines is 0.2 seconds for 10,000 'student records', which has a final string size of ~1.4mb. I realize this is quite bizarre, just wondering if there are any inherent problems with creating and splitting such large strings using javascript? I don't know how different browsers implement their javascript engines. I've tried this on the 'major' browsers, but don't know how this would perform on earlier versions of each. Yeah looking for any comments on this, this is more for fun than anything else! Thanks

  • Unit testing a method with many possible outcomes

    - by Cthulhu
    I've built a simple~ish method that constructs an URL out of approximately 5 parts: base address, port, path, 'action', and a set of parameters. Out of these, only the address part is mandatory, the other parts are all optional. A valid URL has to come out of the method for each permutation of input parameters, such as: address address port address port path address path address action address path action address port action address port path action address action params address path action params address port action params address port path action params andsoforth. The basic approach for this is to write one unit test for each of these possible outcomes, each unit test passing the address and any of the optional parameters to the method, and testing the outcome against the expected output. However, I wonder, is there a Better (tm) way to handle a case like this? Are there any (good) unit test patterns for this? (rant) I only now realize that I've learned to write unit tests a few years ago, but never really (feel like) I've advanced in the area, and that every unit test is a repeat of building parameters, expected outcome, filling mock objects, calling a method and testing the outcome against the expected outcome. I'm pretty sure this is the way to go in unit testing, but it gets kinda tedious, yanno. Advice on that matter is always welcome. (/rant) (note) christmas weekend approaching, probably won't reply to suggestions until next week. (/note)

  • google app engine atomic section???

    - by bokertov
    hi, Say you retrieve a set of records from the datastore (something like: select * from MyClass where reserved='false'). how do i ensure that another user doesn't set the reserved is still false? I've looked in the Transaction documentation and got shocked from google's solution which is to catch the exception and retry in a loop. Any solution that I'm missing - it's hard to believe that there's no way to have an atomic operation in this environment. (btw - i could use 'syncronize' inside the servlet but i think it's not valid as there's no way to ensure that there's only one instance of the servlet object, isn't it? same applies to static variable solution) Any idea on how to solve??? (here's the google solution: http://code.google.com/appengine/docs/java/datastore/transactions.html#Entity_Groups look at: Key k = KeyFactory.createKey("Employee", "k12345"); Employee e = pm.getObjectById(Employee.class, k); e.counter += 1; pm.makePersistent(e); This requires a transaction because the value may be updated by another user after this code fetches the object, but before it saves the modified object. Without a transaction, the user's request will use the value of counter prior to the other user's update, and the save will overwrite the new value. With a transaction, the application is told about the other user's update. If the entity is updated during the transaction, then the transaction fails with an exception. The application can repeat the transaction to use the new data. THANKS!

  • Cost of logic in a query

    - by FrustratedWithFormsDesigner
    I have a query that looks something like this: select xmlelement("rootNode", (case when XH.ID is not null then xmlelement("xhID", XH.ID) else xmlelement("xhID", xmlattributes('true' AS "xsi:nil"), XH.ID) end), (case when XH.SER_NUM is not null then xmlelement("serialNumber", XH.SER_NUM) else xmlelement("serialNumber", xmlattributes('true' AS "xsi:nil"), XH.SER_NUM) end), /*repeat this pattern for many more columns from the same table...*/ FROM XH WHERE XH.ID = 'SOMETHINGOROTHER' It's ugly and I don't like it, and it is also the slowest executing query (there are others of similar form, but much smaller and they aren't causing any major problems - yet). Maintenance is relatively easy as this is mostly a generated query, but my concern now is for performance. I am wondering how much of an overhead there is for all of these case expressions. To see if there was any difference, I wrote another version of this query as: select xmlelement("rootNode", xmlforest(XH.ID, XH.SER_NUM,... (I know that this query does not produce exactly the same, thing, my plan was to move the logic to PL/SQL or XSL) I tried to get execution plans for both versions, but they are the same. I'm guessing that the logic does not get factored into the execution plan. My gut tells me the second version should execute faster, but I'd like some way to prove that (other than writing a PL/SQL test function with timing statements before and after the query and running that code over and over again to get a test sample). Is it possible to get a good idea of how much the case-when will cost? Also, I could write the case-when using the decode function instead. Would that perform better (than case-statements)?

  • Fix DB duplicate entries (MySQL bug)

    - by Silence
    I'm using MySQL 4.1. Some tables have duplicates entries that go against the constraints. When I try to group rows, MySQL doesn't recognise the rows as being similar. Example: Table A has a column "Name" with the Unique proprety. The table contains one row with the name 'Hach?' and one row with the same name but a square at the end instead of the '?' (which I can't reproduce in this textfield) A "Group by" on these 2 rows return 2 separate rows This cause several problems including the fact that I can't export and reimport the database. On reimporting an error mentions that a Insert has failed because it violates a constraint. In theory I could try to import, wait for the first error, fix the import script and the original DB, and repeat. In pratice, that would take forever. Is there a way to list all the anomalies or force the database to recheck constraints (and list all the values/rows that go against them) ? I can supply the .MYD file if it can be helpful.

  • WP7 - group of textboxes into some sort of template?

    - by Jeff V
    I'm still pretty new at Silverlight so there might be a way to do this, but I'm just unfamiliar with the terminology... I basically have this grouping of textboxes and textblocks and I would like to repeat this same grouping whenever the addNew button is clicked. Is there a way to do this by creating some sort of template? Or do I have to add each item individually. <Grid> <toolkit:ListPicker Height="70" HorizontalAlignment="Right" Name="listPicker1" VerticalAlignment="Top" Width="56" ItemTemplate="{StaticResource PickerItemTemplate}" FullModeItemTemplate="{StaticResource PickerFullModeItemTemplate}" Margin="0,97,167,0"></toolkit:ListPicker> <TextBlock Height="33" HorizontalAlignment="Left" Margin="10,7,0,0" Name="tbDate" Text="Date:" VerticalAlignment="Top" Width="266" /> <TextBlock Height="42" HorizontalAlignment="Left" Margin="9,55,0,0" Name="tbItem" Text="Item:" VerticalAlignment="Top" Width="90" /> <TextBox Height="75" HorizontalAlignment="Left" Margin="92,33,0,0" Name="tbItemName" Text="" VerticalAlignment="Top" Width="341" /> <TextBlock Height="42" HorizontalAlignment="Left" Margin="5,118,0,0" Name="tbServing" Text="Serving:" VerticalAlignment="Top" Width="99" /> <TextBox Height="70" HorizontalAlignment="Left" Margin="90,96,0,0" Name="tbServingValue" Text="" VerticalAlignment="Top" Width="75" /> <TextBlock Height="42" HorizontalAlignment="Left" Margin="156,120,0,0" Name="tbUOM" Text="UOM:" VerticalAlignment="Top" Width="60" /> <Button Content="" HorizontalAlignment="Right" Height="63" Margin="0,100,13,0" VerticalAlignment="Top" Width="132" RenderTransformOrigin="0.455,0.286" Style="{StaticResource wp7_buttonAddNew}" x:Name="btnAddNewItem" Click="btnAddNewItem_Click"/> </Grid> Thanks!

  • Display a summary of form element values before submit

    - by Dirty Bird Design
    Using jquery formtowizard.js with an ajax submit. I want the last step of the form to display a summary of all form fields that were filled out. I can get it to work in isolated test cases, but not in full use. Form <form id="Commission" method="post" action="PHP/CommissionsSubmit.php"> <fieldset id="Initial"> <legend>Enter Your Information</legend> <ul> <li> <label for="FName">First Name*</label><input type="text" name="FName" id="FName"> </li> //repeat many li's </ul> </fieldset> <fieldset> <legend>Second Step</legend> //more li's </fieldset> <fieldset> <legend>Confirmation</legend> <span id="CFName"></span> </fieldset> </form> the jquery to get "#CFName" value $('#FName').keyup(function() { $('#CFName').val($(this).val()); }); I can't get the value to appear in the span "#CFName"... Could this have to do with the "serialize" function or anything going on with my $ajax submit function? its happening before submit... Please help! I apologize, but I've gone back and forth with "#CFName" being a span and an input, using .val and .html respectively

  • Active State Image Display

    - by fmz
    I have some images that need to change, based not only on hover, but also on active state. If you look at the page here: http://site427.mysite4now.net/tazthedog/site1/ There are some tabs with Screen Printing Quick Links, etc. The tab image is associated with the link and displays properly. The icon in tabs defaults to the gray and turns blue on mouse over, however, I also need it to be blue on the "active" state. Here is the css: .quick-links em:hover { background: transparent url(../images/quick-links.png) 10px 9px no-repeat ; display: block ; float: left; } Here is the html: <ul class="tabs"> <li class="quick-links"> <a href="#quickLinks" id=""> <em> <span>Screen Printing Quick Links</span> </em> </a> </li> <li class="distributor-ql"> <a href="#distributorQL" id=""> <em> <span>Dealer &amp; Distributor Quick Links</span> </em> </a> </li> </ul> I tried adding a .quick-links em:active... but that doesn't maintain it. I know there is a way to keep the icon blue while in the active state, I just need a little help to understand what that is. Thanks!

  • Drop Down not even showing up in IE6

    - by blackessej
    I've got a drop down menu here that just plain won't show up in IE6. The site works perfectly in every other browser. Seems daft to lose sleep over IE6, I know, but the site is for a demographic who could very well still be using it. Here's the CSS: html { height:100%; } body, p, a, ul, li, ol, h1, h2, h3, h4, h5, h6 { margin:0; padding:0; } body { behavior:url("csshover3.htc"); font-size:14px; font-family:Arial, Helvetica, sans-serif; background-color:#d3d3d3; height:100%; } h1 { font-size:18px; color:#752eca; text-decoration:none; } h2 { font-size:14px; color:#909090; text-decoration:none!important; } p { text-indent:20px; color:#000; } p a { color:#000; text-decoration:underline; } p.foot { text-indent:0px; } p.link { font-size:18px; color:#30F; text-decoration:underline!important; } a { color:#4d2288; text-decoration:none; outline:none; } a:visited { color:#4d2288; } p a:hover { text-decoration:underline!important; } ul#nav { padding:5px; margin:0px auto; width:100%; } ul#nav li a { display:block; font-weight:bold; padding:2px 10px; background:#bacddb; } ul#nav li a:hover { background:#888; color:#fff; } li { list-style:none; float:left; position:relative; width:225px; text-align:center; margin:0px auto; margin-right:4px; border:1px solid #4d2288; } li ul { display:none; position:relative; width:auto; top:0; left:0; margin-left:-1px; } li>ul { top:auto; left:auto; border-top:none; } li:hover ul, li.over ul { display:block; } ul#nav li.current a { background:#b8ab28; } ul#nav li.current a:hover { background:#888; } img { margin:10px 0 5px; } *html img { margin:20px; } .coltextimg { position:relative; float:left; background-position:left bottom; padding:0px 20px 10px 0px; border:none; } #maincontent { width:940px; margin:0px auto; postition:absolute; } *html #maincontent { margin-left:42px; } #header { float:left; width:100%; height:auto!important; height:100%; min-height:100%; margin:0px auto; background-image:url(images/banner_test.jpg); background-repeat:no-repeat; border:2px solid #752eca; -webkit-border-top-left-radius:10px; -webkit-border-top-right-radius:10px; -moz-border-radius-topleft:10px; -moz-border-radius-topright:10px; border-top-left-radius:10px; border-top-right-radius:10px; } .colmask { position:relative; margin-top:160px; clear:both; float:left; width:100%; overflow:hidden; } .colright, .colmid { float:left; width:100%; position:relative; } .col1, .col2 { float:left; position:relative; padding:10px 0 1em 0; overflow:hidden; } .twocol { background:#fff; } .twocol .colmid { right:45%; background:#fff; } .twocol .col1 { width:51%; left:47%; text-align:justify; z-index:0; } .twocol .col2 { width:41%; left:51%; text-align:justify; z-index:0; } .twocol .colimg { border:2px solid #a0a0a0; } .twocol .colvid1 { width:360px; height:240px; } .twocol .colvid2 { width:360px; height:240px; } #footer { text-align:center; font-size:9px; padding:10px 0 1em 0; clear:both; width:100%; height:100%; } *html #footer { height:43px; } #footer p a { text-decoration:none; } #lyr_ddmenu { position:absolute; z-index:1; height:10px; top:120px; float:left; width:1000px; margin:0px auto; padding:5px; } #contact { position:absolute; float:right; font-size:10px; } A.Controls:link { color:#666666; text-decoration:none; font-weight:bold; } A.Controls:visited { color:#666666; text-decoration:none; font-weight:bold; } A.Controls:active { color:#666666; text-decoration:none; font-weight:bold; } A.Controls:hover { color:#be0000; text-decoration:none; font-weight:bold; } And here's the html I'm having the specific problem with: <div id="maincontent"> <div id="header"> <div id="lyr_ddmenu"> <ul id="nav"> <li class="current"><href here...</a> <ul class="sub"> <li><href here...</a></li> <li><href here...</a></li> <li><href here...</a></li> <li><href here...</a></li> <li><href here...</a></li> </ul></li> <li><href here...</a></li> <ul class="sub"> <li><href here...</a></li> <li><href here...</a></li> <li><href here...</a></li> <li><href here...</a></li> </ul></li> <li><href here...</a></li> <li><href here...</a></li> <ul class="sub"> <li><href here...</a></li> </ul></li> </ul> </div> Thanks!

  • jQuery toggle pushing other elements around... bullies!!

    - by tony noriega
    Ok, so in the left_col of my page, i have a list UL LI that incorporates a jQuery toggle to open a small box, which is "LoginBox". <ul> <li class="members"><a href="/members/signon.asp?userType=member">Members</a></li> <li class="employers"><a href="/employers/signon.asp?userType=employer">Employers</a></li> <li class="providers"><a href="#LoginBox" class="clicker">Providers</a></li> <div class="loginbox" id="LoginBox"> <p>Medical</p> <p>Dental</p> </div> <li class="brokers"><a href="/brokers/signon.asp?userType=broker">Brokers</a></li> </ul> when the jQuery is invoked, it pushes the elements below it down. As expected. What i dont get is that i have an H3 tag below this UL LI which has a background image. The text portion of the H3 gets pushed down, but the background image seems to stay put, and the UL LI that gets pushed down just covers up the background image of the H3. why would the text move, but not the background image itself? here is the H3 style: .sectionmenu h3{ background: url(/_images/h3-triangle.gif) left center no-repeat; color: #000; font-size: 12px; font-weight: bold; padding: 4px 0px 4px 10px; margin: 0; border-bottom:1px dotted #aeaeae;; } and the login box style: .loginbox{ display:none; width:100px; height:50px; margin:0 0 0 77px; }

  • Making a visual bar timer for iPhone

    - by Ohmnastrum
    I've looked up all results for progress bars and changing the width of an image but it only refers to scaling, and the progress bars aren't customizable so that they fit other functions or design schemes... unless I missed that part. I'm trying to make a bar timer that crops off of the right over a period of time. I tried using an NStimer so that it would subtract from a value each time its function is called. the Timerbar function gets called as a result of another timer invalidating and it works. What doesn't work is that the width isn't changing just the position. further more I keep getting values like Inf and 0 for power and pwrBarWidth I was sure that the changes would occur when Mult was plugged into the equation. it seems like casting mult as an int is causing problems but i'm not sure exactly how. int pwrBarMaxWidth = 137; int pwrBarWidth 0; int limit = 1; float mult; float power = 0; -(void) Timerbar:(NSTimer *)barTimer { if(!waitForPlayer) { [barTimer invalidate]; } if(mult > 0.0) { mult -= 0.001 * [colorChoices count]; if(mult < 0.0) { mult = 0.0; } } power = (mult * 10) / pwrBarMaxWidth; pwrBarWidth = (int)power % limit; // causes the bar to repeat after it reaches a certain point //At this point however the variable Power is always "inf" and PwrBarWidth is always 0. [powerBar setBounds:CGRectMake(powerBar.frame.origin.x, powerBar.frame.origin.y,pwrBarWidth,20)]; //supposed to change the crop of the bar } Any reason why I'm getting inf as a value for power, 0 as a value for pwrBarWidth, and the bar itself isn't cropping? if this question is a bit vague i'll provide more information as needed.

  • Quickest way to compare a buch of array or list of values.

    - by zapping
    Can you please let me know on the quickest and efficient way to compare a large set of values. Its like there are a list of parent codes(string) and each code has a series of child values(string). The child lists have to be compared with each other and find out duplicates and count how many times they repeat. code1(code1_value1, code1_value2, code3_value3, ..., code1_valueN); code2(code2_value1, code1_value2, code2_value3, ..., code2_valueN); code3(code2_value1, code3_value2, code3_value3, ..., code3_valueN); . . . codeN(codeN_value1, codeN_value2, codeN_value3, ..., codeN_valueN); The lists are huge say like there are 100 parent codes and each has about 250 values in them. There will not be duplicates within a code list. Doing it in java and the solution i could figure out is. Store the values of first set of code in as codeMap.put(codeValue, duplicateCount). The count initialized to 0. Then compare the rest of the values with this. If its in the map then increment the count otherwise append it to the map. The downfall of this is to get the duplicates. Another iteration needs to be performed on a very large list. An alternative is to maintain another hashmap for duplicates like duplicateCodeMap.put(codeValue, duplicateCount) and change the initial hashmap to codeMap.put(codeValue, codeValue). Speed is what is requirement. Hope one of you can help me with it.

    I am trying to understand the basic concepts of OpenGL. A week into it, I am still far from there. Once I am in glsl, I know what to do but I find getting there is the tricky bit. I am currently able to pass in video pixels which I manipulate and present. I have then been trying to add still image as an overlay. This is where I get lost. My end goal is to end up in the same fragment shader with pixel data from both my video and my still image. I imagine this means I need two textures and pass on two pixel buffers. I am currently passing the video pixels like this: glGenTextures(1, &textures[0]); //target, texture glBindTexture(GL_TEXTURE_2D, textures[0]); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE); glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE); glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_BGRA, GL_UNSIGNED_BYTE, buffer); Would I then repeat this process on textures[1] with the second buffer from the image? If so, do I then bind both GL_TEXTURE0 and GL_TEXTURE1? ...and would my shader look something like this? uniform sampler2D videoData; uniform sampler2D imageData; once I am in the shader? It seems no matter what combination I try, image and video always ends up being just video data in both these. Sorry for the many questions merged in here, just want to clear my many assumptions and move on. To clarify the question a bit, what do I need to do to add pixels from a still image in the process described? ("easy to understand" sample code or any types of hints would be appreciated).

  • Link failure with either abnormal memory consumption or LNK1106 in Visual Studio 2005.

    - by Corvin
    Hello, I am trying to build a solution for windows XP in Visual Studio 2005. This solution contains 81 projects (static libs, exe's, dlls) and is being successfully used by our partners. I copied the solution bundle from their repository and tried setting it up on 3 similar machines of people in our group. I was successful on two machines and the solution failed to build on my machine. The build on my machine encountered two problems: During a simple build creation of the biggest static library (about 522Mb in debug mode) would fail with the message "13libd\ui1d.lib : fatal error LNK1106: invalid file or disk full: cannot seek to 0x20101879" Full solution rebuild creates this library, however when it comes to linking the library to main .exe file, devenv.exe spawns link.exe which consumes about 80Mb of physical memory and 250MB of virtual and spawns another link.exe, which does the same. This goes on until the system runs out of memory. On PCs of my colleagues where successful build could be performed, there is only one link.exe process which uses all the memory required for linking (about 500Mb physical). There is a plenty of hard drive space on my machine and the file system is NTFS. All three of our systems are similar - Core2Quad processors, 4Gb of RAM, Windows XP SP3. We are using Visual studio installed from the same source. I tried using a different RAM and CPU, using dedicated graphics adapter to eliminate possibility of video memory sharing influencing the build, putting solution files to different location, using different versions of VS 2005 (Professional, Standard and Team Suite), changing the amount of available virtual memory, running memtest86 and building the project from scratch (i.e. a clean bundle). I have read what MSDN says about LNK1106, none of the cases apply to me except for maybe "out of heap space", however I am not sure how I should fight this. The only idea that I have left is reinstalling the OS, however I am not sure that it would help and I am not sure that my situation wouldn't repeat itself on a different machine. Would anyone have any sort of advice for me? Thanks

  • inconsistent setTexture behavior in cocos2d on iPhone after using CCAnimate/CCAnimation

    - by chillid
    Hi, I have a character that goes through multiple states. The state changes are reflected by means of a sprite image (texture) change. The state change is triggered by a user tapping on the sprite. This works consistently and quite well. I then added an animation during State0. Now, when the user taps - setTexture gets executed to change the texture to reflect State1, however some of the times (unpredictable) it does not change the texture. The code flows as below: // 1. // Create the animation sequence CGRect frame1Rect = CGRectMake(0,32,32,32); CGRect frame2Rect = CGRectMake(32,32,32,32); CCTexture2D* texWithAnimation = [[CCTextureCache sharedTextureCache] addImage:@"Frames0_1_thinkNthickoutline32x32.png"]; id anim = [[[CCAnimation alloc] initWithName:@"Sports" delay:1/25.0] autorelease]; [anim addFrame:[CCSpriteFrame frameWithTexture:texWithAnimation rect:frame1Rect offset:ccp(0,0)]]; [anim addFrame:[CCSpriteFrame frameWithTexture:texWithAnimation rect:frame2Rect offset:ccp(0,0)]]; // Make the animation sequence repeat forever id myAction = [CCAnimate actionWithAnimation: anim restoreOriginalFrame:NO]; // 2. // Run the animation: sports = [[CCRepeatForever alloc] init]; [sports initWithAction:myAction]; [self.sprite runAction:sports]; // 3. stop action on state change and change texture: NSLog(@"Stopping action"); [sprite stopAction:sports]; NSLog(@"Changing texture for kCJSports"); [self setTexture: [[CCTextureCache sharedTextureCache] addImage:@"SportsOpen.png"]]; [self setTextureRect:CGRectMake(0,0,32,64)]; NSLog(@"Changed texture for kCJSports"); Note that all the NSLog lines get logged - and the texture RECT changes - but the image/texture changes only some of the times - fails for around 10-30% of times. Locking/threading/timing issue somewhere? My app (game) is single threaded and I only use the addImage and not the Async version. Any help much appreciated.

  • Iterative Reduction to Null Matrix

    - by user1459032
    Here's the problem: I'm given a matrix like Input: 1 1 1 1 1 1 1 1 1 At each step, I need to find a "second" matrix of 1's and 0's with no two 1's on the same row or column. Then, I'll subtract the second matrix from the original matrix. I will repeat the process until I get a matrix with all 0's. Furthermore, I need to take the least possible number of steps. I need to print all the "second" matrices in O(n) time. In the above example I can get to the null matrix in 3 steps by subtracting these three matrices in order: Expected output: 1 0 0 0 1 0 0 0 1 0 0 1 1 0 0 0 1 0 0 1 0 0 0 1 1 0 0 I have coded an attempt, in which I am finding the first maximum value and creating the second matrices based on the index of that value. But for the above input I am getting 4 output matrices, which is wrong: My output: 1 0 0 0 1 0 0 0 1 0 1 0 1 0 0 0 0 0 0 0 1 0 0 0 1 0 0 0 0 0 0 0 1 0 1 0 My solution works for most of the test cases but fails for the one given above. Can someone give me some pointers on how to proceed, or find an algorithm that guarantees optimality? Test case that works: Input: 0 2 1 0 0 0 3 0 0 Output 0 1 0 0 0 0 1 0 0 0 1 0 0 0 0 1 0 0 0 0 1 0 0 0 1 0 0

  • jQuery how to set click on href in the div?

    - by faya
    Good day, I want to set click event on every anchor element in my div container. Here is an example what I want to do: ---HTML--- <div id="my-container"> <a href="page1.html">page1</a> <a href="page2.html">page2</a> <a href="page3.html">page3</a> </div> ---- jQuery ---- $("#my-container a").click(function() { var link = $(this).attr("href"); $("#my-container").load(link); }); What I want to do is to let me handle loading event of href clicks and load it to the same container. And this is must done without id, class attributes which aren't available for that hrefs. The problem is in this: $("#my-container a"). Any help would be appreciated! Thanks UPDATE People doesn't seem to get right what I wanted to ask. I repeat myself again. $("#my-container a") <---- doesn't add click events on href anchors. So how I can set click event?

I have a filter in filter.js who show just the fields in this category. <li data-ng-repeat="category in categoryList"> <a data-ng-click="setSelectedClient()" class="btn">{{category.name}}</a></li> I'm receving an error when i click on click on button. I'm looking posts like that but i can't find anything. ReferenceError: _ is not defined at h.$scope.setSelectedClient (http://localhost/Portofolio2/js/controllers.js:60:13)

  • Margin-Top push outer div down

    - by Daniel Hertz
    Hello, I have a header div as the first element in my wrapper div, but when I add a top margin to a h1 inside the header div it pushes the entire header div down. I realize this happens whenever I apply a top margin to the first visible element on a page. Here is a sample of the css. Thanks! div#header{ width: 100%; background-color: #000; position: relative; } div#header h1{ text-align: center; width: 375px; height: 50px; margin: 0 auto; font-size: 220%; text-indent: -5000px; background: url('../../images/name_logo.png') no-repeat; } html part <div id="header"> <h1><a href="/home.php">Title</a></h1> <ul id="navbar">
