  • Do I need to change the package name for the free version of my app?

    - by teedyay
    I have an application that I'm going to publish to the Android market. I'm planning on releasing a paid-for version and a free version with restricted feature set. During development I've ensured I can turn features on and off by setting a few constant values, so I only have one codebase. However, now I come to release I'm not clear if I need to make a copy of the app with a different package name for the free version. The documentation on how the market works say updates will only be recognised if they have the same package name and are signed with the same key. Does this mean it's OK to release two applications with the same package name but signed with different keys, or will this break something? Or is it just bad practice?

  • How can I enable auto-updates in a Qt cross-platform app?

    - by FX
    I love applications that are able to update themselves without any effort from the user (think: Sparkle framework for Mac). Is there any code/library I can leverage to do this in a Qt app, without having to worry about the OS details? At least for Windows/Mac/user-owned-linux-binaries. I could integrate Sparkle on the Mac version, code something for the linux case (only for a standalone, user-owned binary; I won't mess with distros packaging, if my program is ever packaged), and find someone to help me on the Windows side, but that's horribly painful. Surely I'm not the only one who wants to provide this to users?

  • How to do safely test Biztalk app by manipulating the Windows OS system time w/o breaking the Active Directory?

    - by melaos
    i have a biztalk - window service tied middleware application which talks to other system. recently we had a request to test for scenarios which relates to the date. as we have a lot of places in the application which uses the .net Datetime.Now value, we don't really want to go into the code level and change all these values. so we're looking at the simplest way to test which is to just change the OS time. but what we notice is that sometimes when we change the system date time, we will get account lock out due to Active Directory. So my question is what's a good and safe way that i can test for future dates, etc by changing the windows OS system date time but without causing any issues with the Active Directory. And where can i find out more about AD and how it issues token and what's the correlation with the system date time changes. Thanks! ~m

  • Is there a slick way to deploy my silverlight app and change settings programmatically?

    - by MIke S.
    I am fairly new to web development. I am at the point of deployment (for testing). I have a few places (maybe 4 places) where I had to add a URI that was non-relative into the appliation. So now, at deployment, those need to be changed. Is there a slick way of handling this? By slick I mean not manually going through the app and changing the URIs or a blanket find and replace (too risky). I only have 4 places to change now, but this could easily change and cause deployment issues. I am using a Microsoft technology stack. Silverlight, ASP.NET, RIA, etc. Development is done in Visual Studio 2010. I noticed that the web projects have a nifty transformation for the web.config...which is nice. Is there an equivalent mechanism for silverlight resources? Any other ways? Any thoughts?

  • File name containing more than 16 characters inside parentheses failing

    - by Tom anMoney
    I am generating file names that contain a timestamp in the following format: "base_name (yyyy-mm-dd hhmmss).ext" This seems to cause a problem on Android. Here's my log: /storage/sdcard0/anMoney/transfer/Net worth over time _ Forecast (2012-11-19 110550).pdf E/Gmail (11802): java.io.FileNotFoundException: /storage/sdcard0/myapp/transfer/Net worth over time _ Forecast (2012-11-19 110550).pdf: open failed: ENOENT (No such file or directory) E/Gmail (11802): at libcore.io.IoBridge.open(IoBridge.java:416) E/Gmail (11802): at java.io.FileInputStream.<init>(FileInputStream.java:78) E/Gmail (11802): at java.io.FileInputStream.<init>(FileInputStream.java:105) E/Gmail (11802): at android.content.ContentResolver.openInputStream(ContentResolver.java:445) E/Gmail (11802): at com.google.android.gm.provider.MailEngine.cacheAttachment(MailEngine.java:3054) E/Gmail (11802): at com.google.android.gm.provider.MailEngine.sendOrSaveDraft(MailEngine.java:2746) E/Gmail (11802): at com.google.android.gm.provider.MailProvider.sendOrSaveDraft(MailProvider.java:477) E/Gmail (11802): at com.google.android.gm.provider.MailProvider.insert(MailProvider.java:534) E/Gmail (11802): at android.content.ContentProvider$Transport.insert(ContentProvider.java:201) E/Gmail (11802): at android.content.ContentResolver.insert(ContentResolver.java:864) E/Gmail (11802): at com.google.android.gm.provider.Gmail$MessageModification.sendOrSaveNewMessage(Gmail.java:3576) E/Gmail (11802): at com.google.android.gm.ComposeActivity$SendOrSaveTask$1.onInitializationComplete(ComposeActivity.java:1765) E/Gmail (11802): at com.google.android.gm.provider.MailEngine$5.run(MailEngine.java:1006) E/Gmail (11802): at android.os.Handler.handleCallback(Handler.java:615) E/Gmail (11802): at android.os.Handler.dispatchMessage(Handler.java:92) E/Gmail (11802): at android.os.Looper.loop(Looper.java:137) E/Gmail (11802): at android.os.HandlerThread.run(HandlerThread.java:60) E/Gmail (11802): Caused by: libcore.io.ErrnoException: open failed: ENOENT (No such file or directory) Now, if I trim the file name to have only 16 characters within the parentheses, everything is working as expected. I am able to send the file as a GMail attachment. The following file name is working fine: /storage/sdcard0/myapp/transfer/Net worth over time _ Forecast (2012-11-19 11070).pdf I tried the following troubleshooting: It's not the overall length of the file name, as if I shorten the base name, the same behavior remains It's not GMail, uploading the file to Google Drive fails similarly 16 characters inside the parentheses work, but not 17 It's not the space character inside the parentheses that causes the issue, as I replaced it with a dash and it's the same problem. Anybody has any ideas on what's going on here?

  • What happens to a transaction when App Pool recycles or the worker process is terminated forcefully?

    - by ARS
    The architecture of the application is straight forward. There is a web application which maintain account holder data. This data is processed and the status of account holders is updated based on number of business rules. This process is initiated using a button on the page and is a long running process (say 15 mins). A component is developed to do this data processing which internally calls stored procedures. Most of the business rules are kept in stored procedure. To handle timeouts the processing is done asynchornously(using Thread Pool or custom thread or Async Callback Delegates). The entire process run under a transaction. I would like to know your view on what happens to the transaction if the app pool is recycled or the worker process is terminated forcefully?

  • Data format for content heavy iPhone app - Plist or XML?

    - by Toby
    Hello, I'm building an iPhone app that is essentially a book, it will be bundled with a lot of text-heavy content. I considered bundling the data as XML and load it when the application starts but the XML would contain a lot of nested structures and be a bit of a pain to parse. Would it be better to use a plist? I'm concerned about memory usage and plists are loaded entirely into memory - can they be parsed in chunks? Is there a maximum size to a plist and how efficient are they? I'm not sure how big the bundled content is going to be yet but I should imagine it could be anywhere from 500k to 4MB. Thanks in advance.

  • How to replicate Google "Hangouts On Air" stream combining functionality?

    - by Rob Olmos
    I've been researching this one for quite a bit but haven't found any solid leads. I have a Wowza/Flash app with video chatroom functionality and would like to combine the streams server-side into one video/audio stream in order to be sent to a live Youtube channel. I've found a couple projects such as jMixer and some helpful keywords such as "vision mixer" to help with my search but looking for any previous experience or new ideas. The other option is building something like it myself with a commercial video decoding/encoding library to raw frames, stitching the frames together, then encoding it. I was originally going down this route but put project on hold. What are some ideas, keywords, or existing software (open source preferred) to take those live streams and combine them into one in real-time? Or is coding it myself the required route? Thanks!

  • How to add "loading" screen for UIWebView app each time new page is being loaded?

    - by AragornSG
    I have an app that works with tabs and webview. I already have it setup to refresh the page assigned to a tab each time the item on tabbar is selected. My problem now is that it takes some time to load the page and it's impossible to say if the page being displayed is the old or refreshed one. What I want to do is add a "loading" screen (a simple image) which will be displayed until the refreshed page is loaded. Here is the function I run on each tab tap: - (void) goToPage:(NSString *)sid { NSString *newURL = [NSString stringWithFormat:@"%@/mykingdom.php?sid=%@", appURL, sid]; [secondView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:newURL]]]; } Thanks!

  • Run shell script on Linux box from a shortcut/app in Android?

    - by melat0nin
    I have an Ubuntu box which runs XBMC, which crashes occasionally. Since I have no keyboard connected,I have to SSH in, kill xinit, then restart it. I was wondering if there's an elegant way of doing this from my Android tablet, so I don't have to go to my desktop PC. I've used ConnectBot and can log in, but typing is laborious, even using the edit keys to scroll back up through the buffer. It seems as though it should be possible to script this so that I can execute a shortcut, or at least select a predefined script to be executed. This would seem to have plenty of applications, and there could be a site of scripts - restart webserver, reboot, email logs etc

  • Where does the data model go in a Prism app?

    - by HawkeyeJoeS
    I'm having trouble where to put our data model in our Prism app. Most, if not all or our data will be coming from web services and the web services are unique for each module. Unfortunately, there will be objects that need to be shared (such as a person/user object). I'm really torn about whether to add these services directly to the module, so that each is truly independent, or create a separate project to house the web service proxies and business entities. The modules are being built by different teams, but will all live in the same solution (and source control, of course).

  • How to make a swing app aware of screen size change?

    - by Marton Sigmond
    Hi, while my swing app is running I change the size of the screen (e.g. from 1024x768 to 800x600). Is there any event I can listen to to be notified about this? Alternatively I could check the screen size in every couple of second, but the Toolkit.getScreenSize() keeps telling me the old value. How could I get the real screen size after the change? Environment: Linux (tested on SuSE ES 11 and Ubuntu 9.04) I appreciate your help. Marton

  • I have a problem implementing states in my Flex app, please help!

    - by ben
    Hey guys, I'm trying to work out how to use states in my Flex app. I've created two states, State1 and Stage 2. Both are based off the base state. I've created a few visual elements for State1, and given each of them includeIn="State1". But when I'm in design mode and click on State2, these elements are still visible? Why is that? If I try to delete them while State2 is selected, all that happens is RemoveChild is added to the State2 tag. Is this how I'm supposed to do it? Thanks for reading!

  • Are vector assignments copied by value or by reference in Google's Go language?

    - by Brian T Hannan
    In the following code, I create one peg puzzle then do a move on it which adds a move to its movesAlreadyDone vector. Then I create another peg puzzle then do a move on it which adds a move to its movesAlreadyDone vector. When I print out the values in that vector for the second one, it has the move in it from the first one along with the move from the second one. Can anyone tell me why it seems to be assigning by reference and not value? Are vector assignments copied by value or by reference in Google's Go language? package main import "fmt" import "container/vector" type Move struct { x0, y0, x1, y1 int } type PegPuzzle struct { movesAlreadyDone * vector.Vector; } func (p *PegPuzzle) InitPegPuzzle(){ p.movesAlreadyDone = vector.New(0); } func NewChildPegPuzzle(parent *PegPuzzle) *PegPuzzle{ retVal := new(PegPuzzle); retVal.movesAlreadyDone = parent.movesAlreadyDone; return retVal } func (p *PegPuzzle) doMove(move Move){ p.movesAlreadyDone.Push(move); } func (p *PegPuzzle) printPuzzleInfo(){ fmt.Printf("-----------START----------------------\n"); fmt.Printf("moves already done: %v\n", p.movesAlreadyDone); fmt.Printf("------------END-----------------------\n"); } func main() { p := new(PegPuzzle); cp1 := new(PegPuzzle); cp2 := new(PegPuzzle); p.InitPegPuzzle(); cp1 = NewChildPegPuzzle(p); cp1.doMove(Move{1,1,2,3}); cp1.printPuzzleInfo(); cp2 = NewChildPegPuzzle(p); cp2.doMove(Move{3,2,5,1}); cp2.printPuzzleInfo(); } Any help will be greatly appreciated. Thanks!

  • Is there a good web-based project management app with scheduling?

    - by Andykiteman
    Ideally something as intuitive as basecamp, with good usability and accessibility. The best I've seen is huddle.net but it's still weak in several areas. Must have: Projects - ability to add people & tasks and schedule tasks to people Calendar - showing when people are busy or available Role based access - Admins and non-admins History - ability to look back at all history Anyone seen a product that's worth a look? Clarification: Must be hosted i.e. not require my own hardware or IT staff I'm looking for an app to schedule people with specific tasks at specific times and monitor the outcomes. I'm already using Mingle (for stories), Basecamp (to run the business) and Exceptional (to track bugs). I'm not looking for a bug-tracking system or a story management application (I already looked at VersionOne, but chose Mingle due to it's nicer UI) My response to the answer being auto-selected: I still don't feel the answer (chosen for me) is the correct one. It's a useful list but little more, and doesn't provide the solution I was seeking.

  • Pass structured data from C++ app to ASP.NET web service.

    - by Odrade
    I have Visual C++ application that needs to communicate with a ASP.NET web service. Specifically, the app needs to pass structured data (e.g. objects that contain lists of structures, etc) as a parameter to one of the service methods. The C++ application is already generating an xml document that contains this data. The document is generating using an xml library, so it should always well-formed. What is a good method for passing this data to the web service? I'm thinking about passing the document to the web service as a string parameter, then deserializing to a .NET object based on an xsd. But, I hear that passing an xml doc as a string parameter is not recommended. So, my questions: What are the pitfalls associated with sending the document as a string parameter, assuming that the document itself is always well-formed? Assuming the above is a bad idea, what are some good alternate approaches?

  • Should a company prevent employees from publishing an app in an appstore in their free time?

    - by Tommy
    My company is trying to pass a policy forbidding distribution of any application (even free) in any appstore for all developers. Their reasoning is that "outside work activities create a conflict of interest". They don't want that "you use your spare time to work on your app, and once it takes off you quit your job" (quoting the Head of Development). A few developers (myself included) have already said it was an abusive, pointless and most of all counter-productive policy (developers will actually be demotivated to work here under such control and to be denied of the freedom to distribute their project). Personally, I think it is actually in the interest of the company to promote side projects (even commercial activities, if there is no conflict). I'm also curious, is that common practice?

  • Secure xml messages being read from database into app.

    - by scope-creep
    I have an app that reads xml from a database using NHibernate Dal. The dal calls stored procedures to read and encapsulate the data from the schema into an xml message, wrap it up to a message and enqueue it on an internal queue for processing. I would to secure the channel from the database reads to the dequeue action. What would be the best way to do it. I was thinking of signing the xml using System.Security.Cryptography.Xml namespace, but is their any other techniques or approaches I need to know about? Any help would be appreciated. Bob.
