  • some problem with iOS 4.2.1

    - by bicbac
    Hi, I've been developing an app with MacBook Pro (MBP) so far. Last week one of my friends gave me new macbook air 11"(MBA). so Now I can test my code with more than one machine with the same version of developing tools - Both machine has Xcode (3.2.5) and iOS SDK 4.2.1). After some point my app starts get terminated suddenly(iPhone sumulator), and I was using MBP. I got no error message whatsoever. it just stops. I reckon the crash comes from dealing with memory, like 'release'/ 'double-release'. (I'm not 100% sure though). Anyway I thought there must be some mistake within my code for sure. -Confusion starts from this part.- With my MBA, on the other hand, I don'y see any crash. It just works fine. There is nothing different between MBA & MBP except the h/w specifications. Same code, same versions of XCode and iOS SDK. Is the fact that no crash at MBA suggesting that I have to look somewhere else than the code itself? I red some article and Q&As on iOS4.2.1 and XCode 3.2.5 that the most recent version of XCode doesn't recognize the iOS 4.2.1 since the 4.2.1 came out later the 3.2.5. Is it the reason? I have no idea at this moment what should be the next move. thanks

  • BufferedImage & ColorModel in Java

    - by spol
    I am using a image processing library in java to manipulate images.The first step I do is I read an image and create a java.awt.Image.BufferedImage object. I do it in this way, BufferedImage sourceImage = ImageIO.read( new File( filePath ) ); The above code creates a BufferedImage ojbect with a DirectColorModel: rmask=ff0000 gmask=ff00 bmask=ff amask=0. This is what happens when I run the above code on my macbook. But when I run this same code on a linux machine (hosted server), this creates a BufferedImage object with ColorModel: #pixelBits = 24 numComponents = 3 color space = java.awt.color.ICC_ColorSpace@c39a20 transparency = 1 has alpha = false isAlphaPre = false. And I use the same jpg image in both the cases. I don't know why the color model on the same image is different when run on mac and linux. The colormodel for mac has 4 components and the colormodel for linux has 3 components.There is a problem arising because of this, the image processing library that I use always assumes that there are always 4 components in the colormodel of the image passed, and it throws array out of bounds exception when run on linux box. But on macbook, it runs fine. I am not sure if I am doing something wrong or there is a problem with the library. Please let me know your thoughts. Also ask me any questions if I am not making sense!

  • creating a Grails application in IntelliJ IDEA 9.0.x fails to prompt for "create-app"

    - by dave
    When I create a Grails application in IntelliJ 9 on Snow Leopard I am not prompted to create an application. IntelliJ finished the wizard and creates an empty project that is not a Grails application. I have tried two different Apple computers (MacBook Pro and Mac Pro) it does not work on either. The same steps on a Linux system results in a prompt to "create-app" and a Grails application. I have already tried the steps in http://stackoverflow.com/questions/470882/intellij-idea-setup-on-os-x Is there a specific place that Grails needs to be installed? Has anyone else seen this behavior? Thanks

  • Configuring gcc compiler switches in Qt / QtCreator / QMake

    - by andand
    I recently tried to use Qt Creator 1.3.2 / Qt 4.6.2 / gcc 4.4.0 (32-bit version) on Windows 7 (64-bit) to compile an application using some of the experimental C++0x extensions and encountered the following (fatal) error: This file requires compiler and library support for the upcoming ISO C++ standard, C++0x. This support is currently experimental, and must be enabled with the -std=c++0x or -std=gnu++0x compiler options. In my search for a solution, I came across this thread, and added the following to the .pro file: CXXFLAGS += -std=c++0x but that didn't seem to make a difference. So, I expect there's some tag I need to add to the .pro (project) file, but I've never messed with the gcc compiler switches in Qt / QMake / QtCreator before, and am uncertain about the proper invokation / incantation. So, my question is how do you set gcc compiler switches when using QtCreator / QMake / Qt?

  • iPhone SDK 3/4 App will not run on a iPhone 2.x device even with deployment target set to 2.0!

    - by MarqueIV
    Ok... I know about the difference between the base/active SDKs and the deployment target. I have my base SDK set at 4.0 and the deployment target set at 2.0. I am not using any APIs post 2.x, conditional or otherwise. Since I can't debug on a 2.x device, after building it, I use the iPhone Configuration Utility to install the app on the device, which it does just fine. Problem is, it doesn't run! I just get a blank screen. The main window never comes up! Now before you ask... I had this same problem with the iPhone SDK 3.x. I upgraded to the 4.x hoping it would be solved. It wasn't. Yes the provisioning profile is installed. (Couldn't install the app if it wasn't.) This same compiled app works fine on 3.x devices. Same with 4.x devices. Just not 2.x devices. Again, no I am not using any post-2.x SDKs. To prove this I created a brand-new, window-based app from the 'New Project' dialog and the only changes I made was the background color of the window (to prove the XIB loaded) and I set the deployment target to 2.0 (It's still compiled against the 4.x SDK though.) Again, it runs fine on 3.x or 4.x devices, but just a black, blank screen on 2.x devices. I've tried this on three separate 2.x devices included one freshly restored. I've used three separate dev machines (MacBook Pro with the 3.x SDK, MacBook Pro with the 4.x SDK and a Mac Pro with the 3.x SDK.) Same result every time. I am stumped. The fact that even an unmodified project doesn't run really has me confused. Could it be the XIB file? Did they change the format from 2.x to something newer in the 3.x SDK? If so, how do I set it back to 2.x. (Again, this is just a complete guess.) But I'm really stumped! Mark

  • Getting started developing an Adobe Premiere plugin?

    - by Moshe
    How do I get started developing a Premiere Pro plugin? I have Premiere Pro CS3 and a working knowledge of VB.NET. (I have experience with a number of other languages that I can use to get around if need be.) Is there an SDK that I'm looking for? Do I need to contact Adobe to join a developer program of sorts? EDIT: Silly me, I've found an SDK on Adobe's site. Where can I find an API or reference?

  • Client side thumb creation OR Server side?

    - by Totty
    Hy, I have two options to choose from: Client side: pro: image manipulations occurs on the client side, so no load on the server cons: more uploaded data Server side: pro: less uploaded data cons: image manipulations occurs on the server side, so there are some load and will be queried... For example, when you upload an image, you will get 4 images: a large image, medium, thumb1, thumb2, so in the case of the client side will be needed to upload the 4 optimized images. For the server side, will be only uploaded 1 optimized image and then manipulated. What is better and less consuming way?

  • HowTo set Icon to Qt Application, created with Qt Visual Studio Add-in?

    - by mosg
    Hello. Here is what I have: Visual Studio 2008 (on 32-bit Windows XP) Qt libraries 4.6.2 for Windows (VS 2008, 194 MB) Visual Studio Add-in (44 MB) After I installed all the software, I created simple Qt Application project, with Visual Studio: menu File | New | Project... and Qt4 Projects | Qt Application.

  • Flash CS5 and dynamic textfields

    - by hood
    I have a "shell" that started life in Flash CS3 (Flash 9, AS3) that has been since used with CS4 and now CS5. It creates TextFields in ActionScript for display (reading the content of those fields from XML). The text fields are either Myriad Pro Regular or Myriad Pro Semibold, both are embedded in the SWF from the Library (any given text field will only use one of those fonts) and using Advanced anti-aliasing. Once a FLA goes into CS5 is still has the same problem when saved back into CS4. The problem is the spacing between letters are now quite random, and the width of each text field is too wide (by about 10%). Changing the letterSpacing property (to something negative) makes this more noticeable. I read on here about Font.registerFont(MyriadPro) but that doesn't seem to be doing anything. Does anyone know how to make CS5 behave like previous versions of Flash? I'm using Flash Professional on Snow Leopard (as part of CS5 Web Premium).

  • The CHOICE : Firebird or H2

    Hi, i have to choice a database to use in server-mode for a java desktop application. I think both are great java database. In my opinion (im NOT well-informed): H2 PRO Is java based Develeopment say it is very very fast Easy to install, configure and use with java application H2 CONS Is a young project Reliability doubt for commercial porpouse FireBird PRO Rock solid project Well documented Should be fast and well optimized for large data Has a java driver... FireBird CONS It is not java based ... ? So, i can't choice between this great db, can i have a suggestion? Thank.

  • XAMPP or MAMP on Mac OS X 10.6.2 (Snow Leopard)

    - by Steve
    I just bought a new MacBook Pro which comes with Snow Leopard 10.6.2 (Mac OS X 10.6.2). I am used to using XAMPP as my local development server on XP. Since Mac OS X is based on Unix, I was thinking on activating/installing all the necessary stuff as I would normally do on Linux. However, I am not quite ready to be playing around with the system at this point so having an external package would be a nice temporary solution I think. The question is whether I should go with MAMP or XAMPP. Does anybody have any suggestions? The Pro and Cons I suppose. As far as I know, Mac OS X comes with Apache2 and PHP5. Would MAMP or XAMPP modify the existing Apache and PHP installation? Any comments on how I should proceed? PS: Eventually I would use the default installation of Apache and PHP, and install a binary package of MySQL but time for development is an essence and I don't have time to familiarize myself with Mac OS X.

  • Why use Oracle Application Express for web app?

    - by Jack
    Hi all. I believe we're moving to Oracle Apex for future development. I've read about Oracle Apex on wikipedia and it's pro and con. It seem to me the con outweigh the pro but maybe I'm wrong. I get the sense that Oracle Apex is for DBA with little or no programing knowledge to setup a web app quickly sort like MS Access for none programmer. If you have Oracle Apex working experience, can you share your though? From wikipedia's entry, it doesn't seem like you need to know any programming language at all but just the PL/SQL? edit: Is Oracle Apex scalable? Can it handle traffic like Facebook's size? Thank. Jack

  • Can't install Acquia Drupal Commons locally

    Working on a MacbookPro OS 10.6.6 , using MAMP Pro 1.9.4. I'm attempting to install Acquia's Drupal Commons locally. The installation progress bar goes all the way, I can check in phpMyadmin that the database has been populated, but before the site configuration screen , I get a 500 Server Error! Standard Drupal 6 or 7 install without any problem & I was able to install Drupal Commons on my web server. So it seems that some form of conflicts happens between my server configuration ( Mamp Pro ) and Drupal Commons. Thanks in advance for any suggestions!

    - by webworm
    When looking to improve Virtual Machine performance what would be better ... Increasing the available RAM or increasing the processor power? Here is my choice ... Core 2 Duo @ 2.4 GHz with 8 GB RAM and integrated graphics (Mac Book Pro 13") Core i7 @ 2.6 GHz with 4 GB RAM and 512 MB dedicated graphics (Mac Book Pro 15") I plan to run Windows x64 in the VM with SQL Server 2008, Visual Studio 2010, and SharePoint 2010. I am planning to run VMWare Fusion v3. I also didn't know if a dedicated graphics card makes a difference when using a Virtual Machine. Thank you.
