  • Migrating a simple application from Application Delegate to ViewController Class

    - by eco_bach
    Hi Frst of all wanted to send out a huge thanks for the great feedback and support. I have a simple application working, right now simply loads a sequence of images and alows the user to step thru the images by clicking a button. All of my logic is in my Application Delegate class, with the image loading, initialization of UIImage Views etc happening in my applicationDidFinishLaunching method. My next step is to migrate as much as possible all of the logic from this class to a ViewController, to take advantage of the extra functionality etc in viewcontrollers. All my images and imageViews are initialized like the following in my applicationDidFinishLaunching. img = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@image1.jpg" ofType:nil]]; imgView = [[UIImageView alloc] initWithImage:img]; How would I migrate this to a ViewController based application? Where would I put all of the logic currently in my applicationDidFinishLaunching method, or for loading of images, is it necessary to only load them here? Any feedback, tips, suggestions appreciated.

  • What is the easiest way to loop through a folder of files in C#?

    - by badpanda
    I am new to C# and am trying to write a program that navigates the local file system using a config file containing relevant filepaths. My question is this: What are the best practices to use when performing file I/O (this will be from the desktop app to a server and back) and file system navigation in C#? I know how to google, and I have found several solutions, but I would like to know which of the various functions is most robust and flexible. As well, if anyone has any tips regarding exception handling for C# file I/O that would also be very helpful. Thanks!!! badPanda

  • JAVA: 500 Worker Threads, what kind of thread pool?

    - by Submerged
    I am wondering if this is the best way to do this. I have about 500 threads that run indefinitely, but Thread.sleep for a minute when done one cycle of processing. ExecutorService es = Executors.newFixedThreadPool(list.size()+1); for (int i = 0; i < list.size(); i++) { es.execute(coreAppVector.elementAt(i)); //coreAppVector is a vector of extends thread objects } I do need a separate threads for each running task, so changing the architecture isn't an option. I tried making my threadPool size equal to Runtime.getRuntime().availableProcessors() which attempted to run all 500 threads, but only let 8 (4xhyperthreading) of them execute. The other threads wouldn't surrender and let other threads have their turn. I tried putting in a wait() and notify(), but still no luck. If anyone has a simple example or some tips, I would be grateful!

  • Optimizing tiled maps in cocos2d-iphone

    - by Omega
    My cocos2d-iphone game has tiled maps. The tilesets textures are rather big. I got around 5 tilesets and each one is 2048x2048 (retina). My maps are around 80x80. They have around 8 layers and each one is obviously using one tileset. The frame rate falls (it goes around 30 sometimes. I know 30 is rather aceptable, but still, I want 50+). So given that textures are huge I can't afford to make many layers (since each one loads a texture of these). So how about I divide my tileset textures into much smaller tilesets (like 1024x1024 each)? That will allow me to use many more layers for my maps, right? Are there any other tips for huge retina display tile maps?

  • SSIS Custom Control Task Debugging UI in BIDS and VS

    - by zeencat
    I've created a SSIS Custom Task in C# and I'm currently developing the UI. I was wondering if there is a better way of debugging the UI instead of compiling the project, copying the DLL's into the appropriate DTS folder and then opening the test Package within BIDS and then attaching the process to Visual Studio. This part I'm not bothered about but once you've tested the UI and made changes to UI within Visual Studio. I've got to recomplile the DLL's and then repeat the entire process. I've got to close BIDS and VS because they don't release the DLL's before I have to start the entire process over again. Does anyone have any tips to speed up this process. It's just so frustrating having to do this everytime.

  • I have the CSS & JS, how do I convert that to erb for my Rails app?

    - by marcamillion
    So I have the foundation of my Rails app, then I went ahead and did the JS and CSS. How do I then take the CSS and JS that I have, and apply it to the app in a 'Rails Way'. i.e. a dynamic way that works nicely. Can you give me some tutorials/articles/resources that I can read up to guide me, please? I have tried the Rails guides, but I find them a bit lacking. Any other good suggestions or tips that might help get me on the right track? Thanks.

  • I just don't know what it is, tried everything, IE 7 bug

    - by Emmy
    Has anyone seen this bug? I have a sidebar with a ul nav background image for the hover state, floated right, looks great in all browsers. Then...I added another div underneath it for ad space. inside, there's an anchored image. That image tucks underneath the background image of the nav, but only in IE7 (i abandoned trying to please ie6). So I took it out of the sidebar, played with float, display,height hacks, but nothing works I can declare a large top margin with some more top padding do get it to clear but it breaks the design. i even tried creating a div called clear and put a top margin there. so it displays with this huge gap in chrome, FF, safari but this tiny space between in IE. i even tried creating a div called clear and put a top margin there. I have spent hours trying to find someone with the same problem but to no avail. Any suggestions? Here's a code snippet: <div id="leftsidebar"> <div id="leftnav"> <ul class="slidenav" id="sidenav"> <li id="overview" class="inactive"> <a href="expat.html">expat lifestyle</a> </li> <li id="tips" class="inactive"> <a href="traveltips.html">travel tips</a> </li> <li id="bts" class="inactive"> <a href="bts-mrt.html">bts/mrt</a> </li> <li id="bus" class="inactive"> <a href="bus.html">bus system</a> </li> <li id="van" class="inactive"> <a href="taxi.html">vans/taxis</a> </li> <li id="boat" class="inactive"> <a href="klong.html">boats/klong</a> </li> <li id="boat" class="inactive"> <a href="klong.html">boats/klong</a> </li> <li id="tuk" class="inactive"> <a href="tuk.html">tuk-tuks</a> </li> <li id="train" class="inactive"> <a href="train.html">trains</a> </li> <li id="airport" class="inactive"> <a href="airport.html">int'l airport</a> </li> <li id="dangers" class="inactive"> <a href="dangers.html">dangers</a> </li> <li id="fun" class="inactive"> <a href="fun.html">fun places</a> </li> <li id="shopping" class="inactive"> <a href="shopping.html">shopping</a> </li> </ul> </div> </div> <div id="store"> <a href="astore.amazon.com/ten044-20"; title="Shop WIB store"> <img src="images/WIBstore.png" height="70" width="200" border="none"/> </a> </div> the corresponding CSS: #leftsidebar { float:right; width: 210px; margin: 40px 0 0 0; padding: 0; height:1%; } #store { margin: 20px 0px 0 0px; padding: 0 10px 0 0; float: right; height: 1%; display: inline; } And an image:

  • SQL help - find the table that has 'somefieldId' as the primary key?

    - by Kettenbach
    Hello All, How can I search my sql database for a table that contains a field 'tiEntityId'. This field is referenced in a stored procedure, but I am unable to identify which table this id is a primary key for? Any suggestions? I currently look through stored procedure definitions for references to text by using something like this Declare @Search varchar(255) SET @Search='[10.10.100.50]' SELECT DISTINCT o.name AS Object_Name,o.type_desc FROM sys.sql_modules m INNER JOIN sys.objects o ON m.object_id=o.object_id WHERE m.definition Like '%'+@Search+'%' ORDER BY 2,1 Any SQL guru's out there know what I need to use to find the table that contains the field, 'preferably the table where that field is the Primary Key. Thanks so much for any tips. Cheers, ~ck in San Diego

  • IE7 is messing up the z-index property with my subnav (although I've already fixed that!)

    - by JAG2007
    OK, so I had this issue with my jQuery subnav in IE7 where it was scrolling down behind the main content after the header. Did a fair bit of research and found a great fix involving simply applying a z-index value to the header, and one to the main content. All was well. Or so I thought. Turns out IE7 is still messing up the subnav z-index within the header itself. The subnav still drops down behind the tagline, which is also part of the header. Particularly when you hit the subnav on the "Help Now" tab. (again, IE7 only) http://betawww.helpcurenow.org I've applied z-index values to both the subnav and the tagline, but that did not resolve the issue as did adding z-index values for the header and maincontent divs. Any tips? Did I specify my z-index improperly with the subnav? (should I have applied to the parent element?)

  • help in security assignment

    - by scatman
    i have to write a program that sniffs network packets (part1-the simple part). and i have to update the program (part2) so that it will be able to terminate connections. the specific requirements are: construct raw packets by specifying data link layer and network layer information including appropriate source and destination MAC and IP addresses. These packets are intended to terminate the connection. To do so, you should used SOCK_RAW as the socket type to be able to set the header information by yourself. can anybody give me some ideas on the second part? should i hijack the session,apply a dos attack on one of the users?? all i need is some tips of how to terminate the connection. i am using c programming language. and this is a course assignment for the security course.

  • How to generate a report of IIS settings for easy perusal?

    - by Bryan
    Hello, I'm looking for a way to (hopefully) create a text file which lists all the settings in IIS for.. Virtual Directories Web sites Which framework is used on a certain website/directory directory of hosted files etc. Basically I want to do some investigation on some of our servers to figure out where certain projects are located, without digging through right clicking and looking for the directory name manually, etc, for every domain we host. The reasoning is that I often need to find access to files/projects I haven't worked on before, but historically, we don't have a strong naming scheme, so you can't just look where something "logically" would be - so, generating a list would be very helpful. Something like this would be awesome, but I'm looking for any tips at all Domainname1.com framework: ASP.NET 1.1 directory: c:\inetpub\wwwroot\domainname1.com Applications hosted at this domain: etc, etc. Plain text, XLS, XML.. anything other than right clicking through the whole list! Thanks!

  • Tableview with sections managed by fetched results controller

    - by Matthes
    Hi, I'm quite new to CoreData and need help with one issue. I have tableview which simply lists cities stored in SQLite db. City is defined by "cityId" and "name" attributes. Data are fetched using NSFetchedResultsController and everything works fine except that I can't figure out how to make FetchedResultsController to group cities by first letter of city names. When I supply "name" for sectionNameKeyPath argument of initWithFetchRequest:managedObjectContext:sectionNameKeyPath:cacheName: method, it creates section for each city, which is obviously something I don't want. I can't figure out how to create an expression which would make it work in way I need. thanks for any tips and/or advices on this Matthes

  • Extracting rightmost N bits of an integer

    - by srandpersonia
    In the yester Code Jam Qualification round http://code.google.com/codejam/contest/dashboard?c=433101#s=a&a=0 , there was a problem called Snapper Chain. From the contest analysis I came to know the problem requires bit twiddling stuff like extracting the rightmost N bits of an integer and checking if they all are 1. I saw a contestant's(Eireksten) code which performed the said operation like below: (((K&(1<<N)-1))==(1<<N)-1) I couldn't understand how this works. What is the use of -1 there in the comparison?. If somebody can explain this, it would be very much useful for us rookies. Also, Any tips on identifying this sort of problems would be much appreciated. I used a naive algorithm to solve this problem and ended up solving only the smaller data set.(It took heck of a time to compile the larger data set which is required to be submitted within 8 minutes.). Thanks in advance.

  • How to drag and scroll in a div with jQuery

    - by Don Munter
    Hey guys, I've been looking around for some time now, but I can't find a way to combine these elements: I want a 100% width div, with 1 row of elements. I need to scroll through this div, just like: http://jqueryfordesigners.com/demo/scrollable-timelines.html So with a hidden overflow and such. But now I want some sort of smooth ease when I let go of the mouseclick, so it'll be like a sort sweep. So when I drag the screen from left to right, and let go of the mouse, it'll move on for 1 sec and linearly slowing down. Hm, am I making sense? Does anyone know of any scripts or some tips to put me back on track? Don

  • Execute jQuery code when images have loaded from external resource

    - by Nick Swan
    Hi all, I'm getting users profile pictures from Facebook so their loading time varies quite a lot. When they have loaded I want to resize them. I have the resizing code working OK, but cannot get the actual code to execute reliably at the right time. According to the info I've found this should work: $('.userPic').load(function () { ... code to resize pictures }); But it doesn't seem 100% reliable. Any other hints or tips? Thanks Nick Swan

  • Programming language for fast calculations with big integers

    - by sub
    I'm doing Project Euler problems at the moment and I can solve most of them using my own programming language which uses direct C++ integers (so they are bound to 2^32 on my machine). However, at times there are problems which require me to work with very high numbers, I can't do that with native integers. So I implemented a BigInt library in my language which unfortunately gets extremely slow at times. Is there a programming language suitable for very efficient handling of big numbers? I mean that I want to do the things I could do in other programming languages with it (variables, loops, etc.), but in a faster way. If you have got tips for workarounds of the 2^32 limit in my language/C++/other languages, please tell me too!

  • Implementation code for GetDateFormat Win32 function

    - by morpheous
    I am porting some legacy code from windows to Linux (Ubuntu Karmic to be precise). I have come across a Win32 function GetDateFormat(). The statements I need to port over are called like this: GetDateFormat(LOCALE_USER_DEFAULT, 0, &datetime, "MMMM", 'January', 31); OR GetDateFormat(LOCALE_USER_DEFAULT, 0, &datetime, "MMMM", 'May', 30); Where datetime is a SYSTEMTIME struct. Does anyone know where I can get the code for the function - or failing that, tips on how to "roll my own" equivalent function?

  • Dojo: dijit.form.DropDownButton content not positioned correctly

    - by Staale
    I have the following setup: <div dojoType="dijit.form.DropDownButton"> <span>Modify</span> <div dojoType="dijit.Menu"> <div dojoType="dijit.MenuItem">...</div> </div> </div> There is of course more to the final setup. The problem I Have is that if I scroll in the page, the popup menu under the DropDownButton comes much higher in the page. I suspect that it's subtracting the scrollOffset for the position off the popup, while in reality that is not needed. Anyone got any tips about how to fix this? I would prefer to use declerative html syntax for using Dojo widgets. == Fixed == I updated to dojo 1.4.2 and this got fixed then.

  • Is there a more efficient way to retrieve tables from websites using wpf + webclient

    - by Jordan Brooker
    new to the community, but here is my first question that I am stuck on. I am new to WPF and WebClient using c# and I am attempting to make a program that access www.nba.com to populate a combobox I have with team names, and then when a user selects a team from the combobox, I wanted to populate a portion of the main window with the roster from the teams home site, same style and eveything. I was able to populate the combobox using the WebClient.OpenRead and reading in the markup to extract the team names. Now I am on the more difficult part. I was planning on using the same method to grab all the markup and then somehow display the table in a content panel, but I feel that this is a very tedious thing to do. Can anyone give me any tips for completing this action or is there a method in the webclient class that allows me to search a webpage for a table or object other than text? Thanks.

  • How do I programmatically nullify a File Attachment in InfoPath Forms

    - by Doctor Zinda
    Howdy all, I'm running into a problem with some InfoPath C# code while trying to remove an attachment from a form. Basically the process is: User opens form User clicks button File attachment is cleared I've tried adding a blank attachment to my schema that never becomes populated, then setting the original field's value equal to that value by the method below. When debugging the form I catch an error: Schema validation found non-data type errors. Any tips here would be appreciated. public void BTN_ClearAttachment_Clicked(object sender, ClickedEventArgs e) { try { _OriginalAttachment.SetValue(_BLANK_ATTACHMENT.Value); } catch (Exception ex) { _ErrorField.SetValue(ex.Message + " : " + ex.StackTrace); } } Thanks, Dr Z Edit - P.S. I should clear up that both _OriginalAttachment & _ErrorField are both XPathNavigators, pointing at different schema elements. I've verified that these XPathNavigators are both pointing at valid schema elements.
