• How do I reduce the height of a TableView when it is constructed in IB?

  - by erotsppa

  I wanted to add a view to the bottom of my screen. The controller is a UITableViewController, how do I shrink the tableView and add a extra view at the bottom of the tableview? I've tried setting the frame of self.tableView in different places (viewDidLoad, viewWillAppear etc) but nothing happens. The tableView is created by IB and not programtically. I've tried added a footer to my table view but that's not what I want, because the footer actually scrolls up, I want a static non moving View at the bottom of the screen.

• UIImageView rotation (NOT the image, but the view)

  - by Kuko

  Hi. How do I rotate the ImageView ... i'm trying to use landscape mode, and have a problem with accelerometer moving the image ... Because when I work in portrait mode the x of accelerometer is the same as the x of the image ... But when I work landscape, the x of accelerometer is the y of the image, because the ImageView autorotates with the parent View. When I rotate the image with CGAffineTransformMakeRotation(M_PI/2), it rotates only the image in it's ImageView... and the x,y sides stays untouched ... Is there any way to make own class which will extend UIImageView where I will swap the x,y sides of a UIImageView ? Or is there some way to rotate the UIImageView, and not only the image in it?

• form update too expensive to be executed in Winform.Timer.Tick

  - by Abruzzo Forte e Gentile

  Hi all I have a WinForm drawing a chart from available data. I programmed it so that every 1 secong the Winform.Timer.Tick event calls a function that: will dequeue all data available will add new points on the chart Right now data to be plotted is really huge and it takes a lot of time to be executed so to update my form. Also Winform.Timer.Tick relies on WM_TIMER , so it executes in the same thread of the Form. Theses 2 things are making my form very UNresponsive. What can I do to solve this issue? I thought the following: moving away from usage of Winform.Timer and start using a System.Threading.Timer use the IsInvokeRequired pattern so I will rely on the .NET ThreadPool. Since I have lots of data, is this a good idea? I have fear that at some point also the ThreadPool will be too long or too big. Can you give me your suggestion about my issue? Thank you very much!

• Trying to extend ActionView::Helpers::FormBuilder

  - by nibbo

  Hello I am trying to DRY up some code by moving some logic into the FormBuilder. After reading the documentation about how to select and alternative form builder the logical solution for me seemed to be something like this. In the view <% form_for @event, :builder => TestFormBuilder do |f| %> <%= f.test %> <%= f.submit 'Update' %> <% end %> and then in app/helpers/application_helper.rb module ApplicationHelper class TestFormBuilder < ActionView::Helpers::FormBuilder def test puts 'apa' end end end This, however, gives me an error at the "form_for" uninitialized constant ActionView::Base::CompiledTemplates::TestFormBuilder Where am I doing it wrong?

• setProperty must be overridden by all subclasses of SOAPMessage

  - by Pablo

  I'm trying to deploy some web services in a WAR application on JBoss 5.1.0. I have created the source files from an existing wsdl using JAX-WS tool wsgen. This created the Service files and @XmlType annotated clases that would act as request and response wrappers. This classes worked well on JBoss 4.2.3, but when moving to JBoss 5.1.0, I get this exception. java.lang.UnsupportedOperationException: setProperty must be overridden by all subclasses of SOAPMessage My configuration: Windows XP SP3 (but getting the same on Vista, as well as on Linux) Sun JDK 1.6.0_17 JBoss 5.1.0 GA for jdk6 Thanks in advance!

• Tortoise SVN tree conflict with myself

  - by Jesse Pepper

  Has anyone had the experience of moving a file in tortoise and committing successfully, only to later commit a different change and be told of a tree conflict where: the file in its original location has been deleted, but in tortoise is marked as missing the file in its new location is there, but marked as already added. (I use tortoise SVN, and we have client and server 1.60) Nobody else changed either the directory or the file (according to svn log). Why is this happening? Is there a way to avoid it happening? If it does happen, is there a more elegant way of fixing the problem than by deleting the whole folder and updating again?

• Parsing HTML with Python 2.7 - HTMLParser, SGMLParser, or Beautiful Soup?

  - by Eric Wilson

  I want to do some screen-scraping with Python 2.7, and I have no context for the differences between HTMLParser, SGMLParser, or Beautiful Soup. Are these all trying to solve the same problem, or do they exist for different reasons? Which is simplest, which is most robust, and which (if any) is the default choice? Also, please let me know if I have overlooked a significant option. Edit: I should mention that I'm not particularly experienced in HTML parsing, and I'm particularly interested in which will get me moving the quickest, with the goal of parsing HTML on one particular site.

• SubWebFolder and mutliple bin folders with Website model?

  - by OutOFTouch

  Hi, I am looking for some advice on how what is the best approach to subweb folders and having mutliple bin folders in the WebSite Project model. For adding new pages at a later stage without recompiling the core files of a website and without building a full fledged Plug-in framework api. I am aware of being able to drop in the compiled dlls into the main bin folder and to just copy over the new page files to a sub folder but I am looking for a more organized file/folder approach. Here is the how it was done with WAP: Moving the Code-Behind Assemblies/DLLs to a different folder than /BIN with ASP.NET 1.1 Multiple /bin folders in ASP.NET I should also mention that I see that I can still do it the old way with the website project model by making the adjustment to the config section mentioned here but I was wondering if that has any side affects. AssemblyBinding in Web Config and XMLNS

• What causes the error "Can't execute code from a freed script"

  - by tjrobinson

  I thought I'd found the solution a while ago (see my blog): If you ever get the JavaScript (or should that be JScript) error "Can't execute code from a freed script" - try moving any meta tags in the head so that they're before your script tags. ...but based on one of the most recent blog comments, the fix I suggested may not work for everyone. I thought this would be a good one to open up to the StackOverflow community.... What causes the error "Can't execute code from a freed script" and what are the solutions/workarounds?

• Redirecting from ASP.NET WebForms to MVC

  - by Paul Gordon

  Hi there, We have a large existing ASP.NET WebForms application, but we are now moving over to MVC. Rather than go through a painful process of trying to integrate MVC into the existing app, we're looking at creating a brand new VS project to completely isolate the new code. As a first step, we are wanting to use the existing login process of the WebForms app, then redirect over to the MVC app. Does anyone know of an easy way to do this (i.e. redirect from a WebForms project to the MVC project, in the same VS solution)? All the information I've found so far suggests either starting from scratch in MVC, or combing MVC into the existing Webforms project - neither of which is very feasible. Many thanks, Paul

• How to determine if a file will be logically moved or physically moved.

  - by Frederic Morin

  The facts: When a file is moved, there's two possibilities: The source and destination file are on the same partition and only the file system index is updated The source and destination are on two different file system and the file need to be moved byte per byte. (aka copy on move) The question: How can I determine if a file will be either logically or physically moved ? I'm transferring large files (700+ megs) and would adopt a different behaviors for each situation. Edit: I've already coded a moving file dialog with a worker thread that perform the blocking io call to copy the file a meg at a time. It provide information to the user like rough estimate of the remaining time and transfer rate. The problem is: how do I know if the file can be moved logically before trying to move it physically ?

• iPhone modalView unwanted offset

  - by Chonch

  Hey, I have a UITabBarController with three view controllers (from three different types). On one of the view controllers, I want to display a modalViewController. Once a UIButton on the screen is pressed, I perform this action: AboutViewController *modalViewController = [[AboutViewController alloc] initWithNibName:@"AboutScreen" bundle:nil]; [self presentModalViewController:modalViewController animated:YES]; like I always do in order to display a modal view... The problem is, that while the modal view is being displayed (while it is moving from the bottom of the screen), a 20 pixels grey strip is showing on the bottom of the screen (the same size as the status bar on the top). Once the modal view reaches its final location, the strip disappears. Needless to say this doesn't look good (to say the least). Does anybody know why this may happen? Thanks,

• Error with Dolphin Boonex Community Framework

  - by Yanki Twizzy

  I just finished moving files from my system to my web host and I am getting this error. I have manually changed the permissions of the tmp folder they are referring to but I keep getting the errror.

• How do I trap the ENTER key in WM 6.1 using C++

  - by Rob King

  Hi,Our barcode scanner application is written in C++ eMbedded V 4.00 and works well on the Motorola MC50 WM5 where the ENTER key is interpreted as an IDOK. We are moving the app to the MC55 with WM6.1 and the ENTER key does not translate to an IDOK. I'm of the impression we will have to programatically trap the key entry (or the value passed on via DataWedge). I have made several attempts to implement either a HOTKEY or something via an Accelerator Table but have been unable to interpret the Microsoft on-line descriptions. If there is a simpler answer that would be good news. If not, a more specific example than the MS samples would be greatly appreciated. Thanks in advance.

• Search algorithm for a sorted double linked list

  - by SalamiArmi

  As a learning excercise, I've just had an attempt at implementing my own 'merge sort' algorithm. I did this on an std::list, which apparently already had the functions sort() and merge() built in. However, I'm planning on moving this over to a linked list of my own making, so the implementation is not particuarly important. The problem lies with the fact that a std::list doesnt have facilities for accessing random nodes, only accessing the front/back and stepping through. I was originally planning on somehow performing a simple binary search through this list, and finding my answer in a few steps. The fact that there are already built in functions in an std::list for performing these kinds of ordering leads me to believe that there is an equally easy way to access the list in the way I want. Anyway, thanks for your help in advance!

• Can everything be done programmatically in WCF or are configuration files for certain features?

  - by CuriousCoder

  I have a strong preference for working in code, leverage IntelliSense and opening up all of the power of the C# language to work with WCF but I want to make sure that I'm not moving in a direction that ultimately will limit the WCF feature set I can access. My experience is so limited with WCF that I don't understand the benefits of using the configuration files, especially if you can do everything in code (?). Note: I'm using .NET 3.5. Can you do 'everything' with WCF programmatically or are configuration files required for the full WCF feature set?

• What technologies should I focus on to work as a developer in Japan?

  - by Atomiton

  I'm thinking of one day moving to Japan and I was wondering if anyone here has any experience working there. I'm curious as to what languages/technology are popular there for web development and software development. I have heard Ruby is/was strong there due to its founder being Japanese. What would you recommend someone focus on if they wanted to work as a developer in Japan? I have heard Microsoft has a strong base in Japan, but my guess is that whatever platform has supported unicode or Shift-JIS the best would be the strongest.

• Can't use FAXCOMEXLib in VS 2010 anymore?

  - by Sam

  I'm just in the process of moving from Visual Studio 2008 to Visual Studio 2010. One of my projects use the Microsoft Fax Service Extended COM Type Library. After converting the project to VS 2010 I get the following compiler error: C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.Targets(1558,9): error MSB3648: The Keycontainer-path "VS_KEY_812A0248FF872DEC" ist invalid. KeyContainer must point to an existing file. C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.Targets(1558,9): warning MSB3283: Wrapperassembly for type library "FAXCOMEXLib" not found. I tried to remove FAXCOMEXLib from the project and adding it again, but it did not help. I got a similar problem with other COM references. How do I resolve this?

• Configure JBOss cache to run on JBoss server 4.2.3.GA

  - by Spiderman

  Our commercial application used to run on different application server and letely we started adjust it to run on JBoss server. The problem is that that application runs JBoss cache and as part of the integration with this framework, the web-inf\lib contains the follwing jars: jboss-aop.jar, jbosscache-core.jar, jboss-common.jar, jboss-common-core.jar, jboss-j2ee.jar, jboss-jmx.jar, jboss-logging-spi.jar This causes a problem to use JNDI through the application because the jboss-common-core.jar contain naming package that cause JBoss JNDI to work incorrect. So I need to find a way to organise my jars that on one hand jboss cache will keep working and on the other hand not to interfere to the work of JNDI Perhaps it include moving the some or all those jars from the web-inf\lib to the /server/default/lib Looking for someone who is familiar in this subject (continue of this thread: http://stackoverflow.com/questions/2847375/problem-configure-jboss-to-work-with-jndi3 )

• Problems with cos and sin in Android

  - by bajen micke

  I have a problem with my code in Android. I am using this to moving a ball. If the degree is 90 it should move to the right, if the degree is 180 it should move down etc. This is the code I have done. int degrees=180; int bollspeed=4; bollX += bollspeed*Math.cos(Math.toRadians(degrees)); bollY += bollspeed*Math.sin(Math.toRadians(degrees)); The problem is that when the ball should move 90 degrees it moves 180, and when it should move 180 degrees it moves 270. I have tested all I could come to think... Can anyone see any error in my code or have a expanation I would be really glad. Thanks

• Accelerometer API for Laptops

  - by FreshCode

  Most IBM (and some Dell) laptops have built-in accelerometers to stop any moving parts during a sudden fall, but I was unable to find a standardised Windows API to access this data. I assume that each manufacturer would provide a driver to interface with the sensor. Which popular laptop brands come standard with accelerometers accessible from an API and which libraries should I use to access the data? Does an API* exist to abstract away the differences between different manufacturers? I am aware of the Windows 7 Sensor API, but I would like support for XP and earlier.

• Paypal adaptive payment API call with C# .NET? Preferably with WebServices

  - by Phil

  Okay I might be entirely off track now but here goes: Our "webshop" offers two functions, buying a specific product and selling it back to us. Back-end handles if the user can sell or not. I've decided to use Paypal's adaptive payments for this one as it seems the way to go doing these kinds of transactions. I've never implemented any kind of shop so I'm totally green with this one. I only recently learned ASP.NET and have mainly developed games before moving to this kind of development. HTTP is still some level of magic to me hehe.. I might be confused but I think paypal offers a webservice with their adaptive payment API. My humble request: A nice soul who wants to share an example of implementing an adaptive payment API call with C# .NET. If they don't offer it as a webservice I'll probably find it as a custom .dll or something. Any tips and examples are highly appreciated! Thanks for reading

• Scala 2.8 Actors

  - by Dave

  Hi, We're looking at using actors in our Scala code quite soon. We're also thinking of moving to Scala 2.8 in the next few weeks. We've been keeping an eye on Akka but it doesn't currently support 2.8 and plans for it have slipped from the 0.7 release to 0.8 We would like distributed, supervised actors. Is there an alternative to Akka? Or does anyone know if Akka 0.8 will definitely have 2.8 support (and when it's scheduled for)? Perhaps it's possible to just use Scala actors for the time being and switch to Akka at a later stage? Thanks, Dave

• MonoDevelop/GTK OS X Usability Issues?

  - by Tylo

  Does anyone else have infuriating usability issues while trying to work with MonoDevelop in OS X Snow Leopard? The ones that interrupt my flow the most are associated with button clicks not responding until I move the window around a little bit. Afterwards, I can get maybe one or two button presses in before I have to repeat moving the window around. I've heard this is a GTK problem that has nothing to do with MonoDevelop in the past and would like to know if anyone else experiences this or has found a way to fix it?

• Question about WinForms TrackBar control in .Net

  - by Jules

  Does anyone know the millisecond interval, used by the framework trackbar, between calling the ValueChanged event when moving the grip with a mouse? I've implemented my own trackbar and I'd like the behaviour to be consistent with what the user expects. I've had a look in reflector but it's one of those controls where most of the implementation is not viewable. ETA: Actually, thinking about it, it's not as simple as that. For small changes, the TrackBar is raising the event for every change. However, if you make a large fast change with the grip, it will not raise the event for every step. Just wondering exactly how the framework does this? Thanks
