• 2 AudioQueue questions

  - by iter

  I am learning to use AudioQueue. I wish to generate an audio stream programmatically. I have 2 issues that I cannot account for. I am getting audio when I run in the simulator, but not on an iPhone. (Other apps do produce sound on the phone). I get about 20ms-long gaps of silence between buffers. In my testing, I generate an audio buffer on startup and repeatedly enqueue it without modification. I don't spend any processing on filling audio buffers at runtime, not even copying them. Ari.

• "Microsoft DNS Client" vs. getaddrinfo?

  - by Josh K

  Right now, my application is using the c-ares asynchronous DNS resolver library on Windows below cURL, and I have users complaining that it behaves differently from other windows apps. One particular user said that "other applications are using the Microsoft DNS client" and experiences no problems. cURL itself has an asynchronous DNS implementation that uses getaddrinfo() in a thread. My guess is that would be equivalent behavior to using the "DNS Client" and its host of functions (e.g. DnsQuery?) So, dear Lazyweb, I ask if there is a tangible difference between the behavior of getaddrinfo() vs. using the actual Dns* APIs from the Win32 API.

• Getting RPXNow and Facebook Open Graph to Play Nicely

  - by ramon.tayag

  A requirement to use the RPXNow is to set your Facebook application's connect url to http://mydomain.rpxnow.com. I was just trying to implement Facebook's Open Graph and I see that it tells you to set the Base Domain to the domain that will contain the app_id. However, Facebook does not allow these two domains to look different. When I try to set the base url to mydomain.com, I get this error: Validation failed. Base Domain is not valid. Connect URL must be derived from your Base Domain. Should I create two apps - one for use with RPXNow, and another for use with Open Graph? If not, what should I do? Thanks

• Load balancing, connection loop

  - by Iapilgrim

  Hi all, I've set up load balancing using Apache, Tomcat through ajp connector. Here the config Apache/httpd.conf BalancerMember ajp://10.0.10.13:8009 route=osmoz-tomcat-1 retry=5 BalancerMember ajp://10.0.10.14:8009 route=osmoz-tomcat-2 retry=5 < Location / Allow From All ProxyPass balancer://tomcatservers/ stickysession=JSESSIONID nofailover=off ProxyPassReverse / < /Location When I try to access https://mycms.net/apps/bo/signin I see the connection loop forever ( redirection forever). I don't know why. This happens sometimes. So my question are: Is there any way Apache make connection loop? Is there a tool help me to monitor the connection? My question may not clear but I don't have any glue right now. Thanks

• Low noise sites to keep track of news related to computers & programming?

  - by Sridhar Ratnakumar

  I am aware of sites like Slashdot and Ars Technica. Unfortunately they publish way too many articles per day. Ars Technical: 100 posts per week Slashdot: 179 posts per week And I prefer not to waste my attention over reading about 180 posts (even if I were to skim) every week. Is there a site that provides only important news - excluding not-so-important news items like top 6 iPad apps that someone is dying to try out (but haven't done yet; still thinks their readers/advertisers care about it)?

• VS 2008 SP1 text editor flickering over remote desktop connection

  - by AltairDusk

  I am connecting from a Windows 7 x64 machine to my dev machine running Windows XP SP3 using the built in remote desktop client. For most apps it works fine with no problems, for Visual Studio whenever I am typing the entire text editor keeps redrawing. I stumbled across this question: http://stackoverflow.com/questions/873849/vs-2008-sp1-over-remote-desktop-constant-repainting and I have tried all of the suggestions in it to no effect, including resetting all VS settings back to default then disabling the suggested settings. Has anyone found a reliable solution to this? I feel like I'm going insane with the screen constantly refreshing when I'm working from home. Some additional information: Remote Desktop is set to run at 1680x1050, 15bit color, Low-speed broadband for the experience setting with all but Visual styles and Persistent bitmap caching unchecked. Visual Studio 2008 Team System is running on the dev machine with Service Pack 1 and Power Commands installed.

• Internationalize HelloWorld program .NET

  - by RockStarInTraining

  I have small test app which has 2 resource files (Resources.resx & Resources.de-DE.resx) with the same exact string names, but one has the strings converted to German. For my form I set the Localize property to ture. In my application I am getting the strings as such: this.Text = Properties.Resources.frmCaption; In my release folder I get a de-DE folder with a dll named International_test.resources.dll. I try to distribute this to a machine which is set to German and all of the strings pulled are still english. I tried keeping the International_test.resources.dll in the de-DE folder or just put in in my apps directory. What am I doing wrong or what do I need to do to get the German resource file to be used?

• What is ltmain.sh, and why does automake say it is missing? What is a good auto (make/conf/etc) gene

  - by gersh

  I just want to develop a C app in linux with the auto(make/conf/...) stuff automatically generated. I tried generating it with ede and anjuta, but it doesn't seem to generate Makefile.am. So, I tried running automake, and it says "ltmain.sh" isn't found. Is there some easy to generate the basic build files for linux C/C++ apps. What is the standard practice? Do most people write these files themselves?

• Measuring code coverage for selenium tests that reside in separate project

  - by ilu

  I have two separate java maven projects: one is my web app itself and other one is tellurium+selenium automation tests for my web(I moved these tests to separate projects as their code doesnt really belong to the web app project code and doesnt use java classes of my web app, also I want to reuse some parts of those tests for testing my other web apps). Therefore, project where my tests reside doesnt know anything about my web app, except tellurium/selenium conf files(host name, credentials, browser). So the question: is there any way to measure code coverage of my webb app backend that is invoked by my tellurium/sellenium tests that reside in separate project? Thanks in advance. Any help is highly appreciated.

• Tutorials for C# database app

  - by ChrisC

  My question and comments here http://stackoverflow.com/questions/2471198/what-is-ado-net shows my level of knowledge about c# database apps. Can someone point me to tutorials and/or primers that can help me proceed from where I am (also stated in other question)? I've looked and all I've found are tutorials that talk about general db basics (ie, not helping with VS/C#), or talk about connecting to existing SQL db's. I need help setting one up and configuring it, as well as help on how to create and use queries to test the db schema.

• How to keep an old VB6 application running in Windows Vista and Windows 7?

  - by MusiGenesis

  I have an old VB6 app which I'm still trying to support. A few users have reported weird crashes when running the app in Vista or Windows 7. The log files don't show anything after one of these crashes, but the customers report that the error message said "OLE something ...", if they saw anything at all. I've never been able to reproduce these crashes while running the program on my own Vista or Windows 7 boxes, so I have essentially no information on what the problem is. My suspicion is that it's a problem with their versions of one or more of the umpteen billion DLLs that a VB6 application is dependent on. The app also uses lame_enc.dll, which introduces a few more dependencies. I'm guessing this is a common problem with VB6 apps (although it's possible that I just sucked as a programmer 10 years ago). Is there some magical installer/updater out there that makes sure all the VB6 dependencies are what they need to be for a VB6 app to function properly?

• Ipad Magazines App How do they work?

  - by Terente Ionut Alexandru

  How are built the magazines apps? For example Popular Science, Auto Trends and PARIS MATCH I want to build an app like this. But how do these app render the content? How the app knows where is an video, an photo, scroll views and so on? Is there any library to use, and do this easy way or do I need my own engine that renders the content? Is just an webView that loads html5, css and java script or is much more than that?

• My first .net web app - should I go straight to MVC framework (c.f. ASP.net)

  - by Greg

  Hi, I'm done some WinForms work in C# but now moving to have to develop a web application front end in .NET (C#). I have experience developing web apps in Ruby on Rails (& a little with Java with JSP pages & struts mvc). Should I jump straight to MVC framework? (as opposed to going ASP.net) That is from the point of view of future direction for Microsoft & as well ease in ramping up from myself. Or if you like, given my experience to date, what would the pros/cons for me re MVC versus ASP.net? thanks

• Best way to reuse a footer menu in Android

  - by Gunnar Lium

  I'm trying to implement a menu in the footer of an app, similar to i.e. the Engadget app. As I understand, getting a standard TabLayout to work in this way is not trivial (if at all possible?). As I see quite a few apps using this interface paradigm, I would assume there is a clever way of doing it. Currently, I'm defining the layout by adding an include line at the end of every layout. This works fine as far as rendering is concerned, but I have to add the onClickListeners to each activity. can we define clickListener through XML? To sum up my question: What is the best way to implement a shared footer navigation accross several Activities?

• How to convert a plist file from mac os project to iphone project?

  - by Tom Pace

  I am developing an app for the iPhone OS devices, and am using a third-party engine which is not well documented but I've made great progress with it anyway. The problem: The engine's developer strongly urges extending from the existing template projects bundled with the engine, but the engine's plist files are Mac OSX project plist files. This is an iPhone engine, and so I cannot understand why the plist file is structured to take keys for Mac OS apps, but that's how it is. I did a FileMerge comparison to ensure there was nothing within the file itself that defined its use for one OS or the other, so I guess it's defined somewhere in the project settings.

• Dashcode and firefox compatibility

  - by nacho4d

  Hi all, I started to use Dashcode with a Safari Custom Project, my apps work fine, but StackLayout Object does not work in Firefox. I know Dashcode use many wekbit-specific things but is there any way I can get StackLayout object o work in Firefox? I would not mind losing some fancy stuff like transition-animations as long as my Views change. StackLayout also does not work in IE, but I think that is too much to expect from IE. lol. Any suggestions, ideas? Maybe jQuery or Dojo libraries can be used with DashCode in case webkit is not available?. in this case how can I do this? Thanks.

• Selling an app to a company - How much to charge?

  - by Moshe

  I wrote an app targeting a particular clientele. A software company with a reputation among my target audience is willing to negotiate a price to either license or buy it. As a newcomer to the app store, I am not sure that I will successfully market it myself. What would be appropriate terms of a sale or license and what about pricing? I am looking for answers that draw from personal experience with software, although not necessarily apps. I've seen this post on SO, but it's a few years old and I assume that the app market has changed and stabilized somewhat. Thanks.

• Database of common translated phrases for localization?

  - by richardtallent

  I'd like to localize my app into a few other languages, all of which I can barely order a drink in. Does anyone know of an online resource for translations of common software menu options, messages, etc. into other languages? Given the number of developers (both OSS and closed-source) that deal with localization, and the overlap of resource strings between, it seems like a pretty obvious fit for a wiki or open source package, but I can't seem to find anything like this. I could try to mine the Windows resource files or dig around in resource strings in robust OSS apps like Firefox, but I suspect I'm not the first person to think of this and surely there is a site that I'm just not finding yet. Update: since nothing exists like this that I could find, I started a feeble attempt at an open-source string library. It's just a boilerplate Google spreadsheet now, so if you want to contribute, please go here: http://www.xark.org/

• WPF: isolated storage file path too long

  - by user342961

  Hi, I'm deploying my WPF app with ClickOnce. When developing locally in Visual Studio, I store files in the isolated storage by calling IsolatedStorageFile.GetUserStoreForDomain(). This works just fine and the generated path is C:\Users\Frederik\AppData\Local\IsolatedStorage\phqduaro.crw\hux3pljr.cnx\StrongName.kkulk3wafjkvclxpwvxmpvslqqwckuh0\Publisher.ui0lr4tpq53mz2v2c0uqx21xze0w22gq\Files\FilerefData\-581750116 (189 chars) But when I deploy my app with ClickOnce, the generated path becomes too long, resulting in a DirectoryNotFoundException when creating the isolated storage directory. The generated path with ClickOnce is: C:\Users\Frederik\AppData\Local\Apps\2.0\Data\OQ0LNXJT.R5V\8539ABHC.ODN\exqu..tion_e07264ceafd7486e_0001.0000_b8f01b38216164a0\Data\StrongName.wy0cojdd3mpvq45404l3gxdklugoanvi\Publisher.ui0lr4tpq53mz2v2c0uqx21xze0w22gq\Files\FilerefData\-581750116 (247 chars) When I browse the folders all but the last directory of the path exists. Then when trying to create a folder at this location windows tells me I can't create a directory because the resulting path name will be too long. How can I shorten the path generated by the IsolatedStorage?

It supports a number of internet capable widgets and web video streaming apps for sites like youtube, twitter & various yahoo! offerings. I'd like to hack on the SDK, but the only version I can find is Japanese. Is there an English version of the SDK? Where can I find some tutorials/examples?

• Data sync solution?

  - by user321088

  For some security issues I'm in an envorinment where third party apps can't access my DB. For this reason I should have some service/tool/script (dunno what yet... i'm open to the best option, still reading to see what I'm gonna do...) which enables me to generate on a regular basis(daily, weekly, monthly) some csv file with all new/modified records for a certain application. I should be able to automate this process and also export at any time a new file. So it should keep track for each application which records he still needs. Each application will need some data in some other format (csv/xls/sql), also some fields will be needed for some application and some aren't... It should be fairly flexible... What is the best option for me? Creating some custom tables for each application? Based on that extracting modified data?

• WinForm Text Control that displays current character/character limit

  - by Refracted Paladin

  I need a way to display, like you see in some web apps, the current characters/character limit for a Text Control(i.e. 3/500). I usually see this as a label residing directly above or below the Text Control. How is this 'normally' accomplished? Should I override my Text Control somehow? Do I just manually add labels by every Text Control and 'bind' them to properties of the Text Control? Do I need to create a composite control that has the Text Control & Label Controls together to accomplish what I need? Any direction or help will be greatly appreciated.

• can I override/redefine "global" Javascript functions, like confirm() and alert()?

  - by EndangeringSpecies

  I want to do some browser automation, and those pesky confirm/alert boxes are a real pain. Disabling javascript completely in this case is not an option, unfortunately. Well, so I was wondering, can I just change the definition of those methods as seen by my browser's javascript interpreter to basically do nothing and return true? Note that I do know about redefining them in the Javascript code directly, e.g. putting in function alert(message) { return true; } but AFAIK this is not a viable approach for this situation because when doing browser automation I have to work with other people's Javascript. Moreover, my program actually begins manipulating these websites already after the page has fully loaded into the browser, so I cannot just first automatically rewrite the javascript and then load the page. Well, so I was wondering if I could instead just "permanently" modify the way alert/confirm are implemented and executed in my browser. Sort of like the equivalent of dll injection and so forth in the realm of windows apps.

• How should jruby-jars and jruby-rack be added to the classpath using warbler?

  - by Ben Hogan

  Hi again, I've been reading through the warbler source code, and I can't figure out how the jruby-jars and jruby-rack jars are meant to end up on the servlet classpath? It seems warbler is copying them into web-inf/gems/gems/<gemname>/lib/<jarname>.jar but they are not on the classpath. I'm guessing that if I put them in my ruby apps lib/ folder they would be copied to web-inf/lib and all would be well, however, it seems odd to have 2 copies of the jar in the war file, is that what I am meant to do?

• What is TombstonedTaskError from App Engine's Task Queue?

  That does the TombstonedTaskError mean? It is being raised while trying to add a task to the queue, from a cron-job: Traceback (most recent call last): File "/base/python_lib/versions/1/google/appengine/ext/webapp/__init__.py", line 501, in __call__ handler.get(*groups) File "/base/data/home/apps/.../tasks.py", line 132, in get ).add(queue_name = 'userfeedcheck') File "/base/python_lib/versions/1/google/appengine/api/labs/taskqueue/taskqueue.py", line 495, in add return Queue(queue_name).add(self) File "/base/python_lib/versions/1/google/appengine/api/labs/taskqueue/taskqueue.py", line 563, in add self.__TranslateError(e) File "/base/python_lib/versions/1/google/appengine/api/labs/taskqueue/taskqueue.py", line 619, in __TranslateError raise TombstonedTaskError(error.error_detail) TombstonedTaskError Searching the documentation only has the following to say: exception TombstonedTaskError(InvalidTaskError) Task has been tombstoned. ..which isn't particularly helpful.
