• Why is unit testing needed in iPhone / iPad ?

  - by Madhup

  Hi, I am developing an application for iPad application. I need to perform unit testing in the application. But I am not sure why I should do unit testing in this application. The applications in these environments are rather small for unit testing to be written. And since the iPhone sentestingkit is not well documented the implementation and wriiting test cases is so time consuming. So why should we waste time in this? And if we have to what should be the best approach to write test cases? Thanks, Madhup

• Getting 0x80131902 when calling COM+ component

  - by Kyle W

  I created a COM+ component in .Net. It needs to use a configuration file, so I've created a directory with an application.manifest and application.config file and set that as the Application Root Directory. Now when I try to create an instance of that object, I get the following HRESULT: 0x80131902. I can't seem to find exactly what this means, except that there is a problem loading the app-domain. If I don't set the Application Root Directory, it loads just fine (but doesn't have access to the config).

• How to initialize log4j properly?

  - by Janusz

  After adding log4j to my application I get the following output every time I execute my application: log4j:WARN No appenders could be found for logger (slideselector.facedata.FaceDataParser). log4j:WARN Please initialize the log4j system properly. It seems this means a configuration file is missing. Where should this config file be located and what is a good start content? I'm using plain java for developing a desktop application. So no webserver etc...

• Embedded Lua on iPhone. What's new and what does it mean?

  - by John Smith

  Apparently Apple has changed some term in the agreement again. From http://www.appleoutsider.com/2010/06/10/hello-lua/ section 3.3.2 is now Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application. instead of the original No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). I am more interested in embedding Lua, but other people have other embeddings they want to make. I am wondering how you ask for permission, and what they mean by the terms "minor features" and "consistent" and how will Apple interpret this section? It seems to have enough loopholes to drive a real firetruck through.

• is background audio playing enabled in iPhone?

  - by Nareshkumar

  I was able to play the audio in background of the application in iPhone. However I would like to know if there is any service that enables the playback of audio after the user exits the application? I know that SDK 4.0 promises multitasking and background processes of the application. But i would like to know if this is enabled for audio playback in the earlier versions?

• Winforms App Not Displaying Graphical Elements in Design Mode

  - by Sev

  I wrote a bunch of code in the .cs file in c# for a winforms application. The application runs fine, and everything is in it's place. Something like this: using.. namespace Temp { public class Temp : Form { Button b1; TextBox t1; Temp() { b1.Text = "Some Text"; b1.Size = new Size(50,20); ... } void function1() { // stuff } static void Main() { Application.Run(new Temp()); } } } How can I modify my code (or fix it somehow) so that the design view displays the elements in their correct positions and view so that I can visually edit them instead of having to trial/error everything. Edit for Clarification My application runs fine. The problem is, that I didn't use designer to create the application and so in the designer view, the app is empty. But not empty when I run it, since everything is positioned programmatically in the .cs file. My question is, how can I fix this, so that the designer shows the objects correctly. There is no quick fix other than to redesign everything?

• How to improve performance of opening Microsoft Word when automated from c#?

  - by Abdullah BaMusa

  I have Microsoft Word template that I automated filling it’s fields from my application, and when the user request print I open this template. but creating word application every time user request print after filling fields is very expensive and lead to some delay while opening the template, so I choose to cache the reference to Word then just open the new filled template. that solve the performance issue as opening file is less expensive than recreating Word each time, but this work while the user just close the document not the entire Word application which when happened my reference to Word become invalid and return with exception says: “The RPC server is unavailable” next time request opening template . I tried to subscribe to BeforClosing event but his trigger for Quitting Word as well as Closing documents. My question is how to know if the word is closing document or quit the entire application so I take the proper action, or any hint for another direction of thinking about improve performance of opening word template.

• How do I ensure GUI responsiveness when using OpenCL on the display GPU?

  - by pauldoo

  In my relatively short time learning OpenCL I frequently see my application cause the operating system UI to become significantly less responsive (several seconds for a window to respond to a drag for example). I have encountered this problem on Windows Vista and Mac OS X both with NVidia GPUs. What can I do when using OpenCL on the same GPU as the display to ensure that my application does not significantly degrade the UI responsiveness like this? Also, can this be done without taking needless performance losses within my application? (Ie, if the user is not doing some UI intensive task then I would not expect my application to run any slower than it does now.) I understand that any answers will be very platform specific (where platform includes OS/GPU/driver combo).

• Any way to add an observer to the head of the queue using Element#observe?

  - by Josh

  This might not be possible but before I rewrite part of my application I wanted to ask... I have a JavaScript app which creates a submit <input> and observes that input's click event using Prototype's Element#observe function. For a few particular pages on one particular site which uses this app, I need to apply some additional business logic before the code which executes normally when the button is clicked. Is there any way I can use Elemen#observe to add my new event handler before the existing event handler, so I can stop the event if these new conditions aren't met? If not I'll probably solve this the "proper" way by having the application fire a specific beforeTakingAction event and add a listener for that which prevents the application from taking it's action, but that's more complicated than this simple problem requires, and requires rewriting part of a shared application for just one user...

• any ways saving user information without db

  - by hguser

  Hi: I have a application which require login,but the number of user who use the application is no more than 40. And In the application,I get some data from the sql server database where I juse have read permission,also I can not create a table in the db for user validate. ALso I do not think it is a good idea to create a user table in other database on another machine.(for example,I can create a user table in the mysql another machine,but is it desireable just for user validating)? Now I just save the user info in a .properties file,any other good idea? BTW,the programe language used in my application is java.

• Money Transaction without using in-app purchase for iphone app

  - by Jaydevsinh Gohil

  I want to implement the payment gateway like functionality in my iphone application other than In-App Purchase feature provided by Apple. So, i have one Question regarding the application approval on Appstore that, if i will redirect user to the UIwebview for payment related functionality, then apple will reject this application for not following the human interface guideline or it will allow this. Other way i can do it by calling web-service for the transaction of money. So, again there is any chance of app rejection on AppStore. Please share your thought on this

• Reset Taskbar Flash in C#

  - by thefactor

  I have an application where the taskbar flashes if an event has occurred. This is working perfectly, and was relatively easy to implement using a Win32 API described below: http://blogs.x2line.com/al/archive/2008/04/19/3392.aspx However, when I stop the flashing, sometimes the application is stuck in the "highlighted" state in the taskbar. This only gets reset by clicking on the application in the taskbar, minimizing it, then re-maximizing it. Is there a way to clear this from being highlighted without any user interaction?

• How to set -Xbootclasspath for a JRE with a custom launcher?

  - by Tom

  I have a Java application which is using a certain Java Runtime Environment. The application uses it's own launcher to startup the java virtual machine. No use of the java.exe, javaw.exe, javaws.exe binaries is being made -- as the application seems to have it's own launcher which is a different executable. This custom launcher is using the rest of the JRE files, such as bin/client/jvm.dll and rt.jar package etc. Now, the problem is that I want to set a boot class path for this custom launcher. The custom launcher does not support the -Xbootclasspath command line parameter, like the default java.exe does. Is there any way for me to set the boot class path now for this java runtime environment? Thanks in advance. Some things to keep in mind: I do not have the source of this application This is meant for self and personal debugging use only, not for distribution

• How can I detect when the .NET Framework feature is "turned off" in Windows 7 / Vista?

  - by John Myczek

  My application requires the .NET Framework version 3.5. I recently ran into a customer that had the .NET Framework installed but turned off on Windows Vista (also applies to Windows 7). In this case, my installer (InstallShield 2009) does not prompt the user to install the Framework (because it is already installed) and when my application runs it crashes immediately. I tried another .NET application and it also crashes immediately. Is there any way to detect this situation and handle it more gracefully? Just detecting this during install is not ideal since the .NET Framework can be turned off at any time. Ideally, the application would be able to check and display a friendly message to the user telling them they need to turn on the .NET Framework. EDIT: "Turning off" the .NET Framework in Windows Vista or Windows 7 is not the same as uninstalling it. The Framework can be simply turned back on without reinstalling: http://windows.microsoft.com/en-US/windows-vista/Turn-Windows-features-on-or-off

• iPhone application build fails with "dyld: Library not loaded: /System/[...]" error? Why?

  - by Andrew J. Brehm

  For my own reasons and not for the app store I am referencing the Apple private framework Apple80211 in an iPhone app. I got the framework from an earlier version of the iPhone SDK. I added the "existing framework", verified that that absolute path to the framework is /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.0.sdk/System/Library/PrivateFrameworks/Apple80211.framework and tried to build the app. But the build (to device) fails with the error dyld: Library not loaded: /System/Library/PrivateFrameworks/Apple80211.framework/Apple80211 Referenced from: /var/mobile/Applications/3691587D-87AF-44EA-A505-F73D17F39B3B/iWire2.app/iWire2 Reason: image not found I cannot figure out why Xcode would look for the library in a /System path (instead of using the path given in the frameworks list) or how to change that behaviour. I tried the tricks I found here and elsewhere for similar (and identical) sitiations: Delete the myusername.* files in the xcodeproj bundle Delete the build directory Clean all targets Start new project Result is always the same. How can I add this (or a) framework to an iPhone project AND get Xcode to at least look at the library located where I point to rather than a location in /System?
