  • Force application to restart on first activity android

    - by Sephy
    Hi, For an unknown reason, I can't get my application leaving properly so that when I push the home button and the app icon again I resume where I was in the app.... But I would like to force the application to restart at the first activity... I suppose this has something to do with onDestroy() or maybe onPause() but I don't know what to do. thanks for any help.

  • Linq to SQL Repository ~theory~ - Generic but now uses Linq to Objects?

    - by Matt Tolliday
    The project I am currently working on used Linq to SQL as an ORM data access technology. Its an MVC3 Web app. The problem I faced was primarily due to the inability to mock (for testing) the DataContext which gets autogenerated by the DBML designer. So to solve this issue (after much reading) I refactored the repository system which was in place - single repository with seperate and duplicated access methods for each table which ended up with something like 300 methods only 10 of which were unique - into a single repository with generic methods taking the table and returning more generic types to the upper reaches of the application. My question revolves more around the design I've used to get thus far and the differences I'm noticing in the structure of the app. 1) Having refactored the code from the dark ages which used classic Linq to SQL queries: public Billing GetBilling(int id) { var result = ( from bil in _bicDc.Billings where bil.BillingId == id select bil).SingleOrDefault(); return (result); } it now looks like: public T GetRecordWhere<T>(Expression<Func<T, bool>> predicate) where T : class { T result; try { result = _dataContext.GetTable<T>().Where(predicate).SingleOrDefault(); } catch (Exception ex) { throw ex; } return result; } and is used by the controller with a query along the lines of: _repository.GetRecordWhere<Billing>(x => x.BillingId == 1); which is fine, and precisely what I wanted to achieve. ...however.... I'm also having to do the following to get precisely the result set i require in the controller class (the highest point of the app in essence)... viewModel.RecentRequests = _model.GetAllRecordsWhere<Billing>(x => x.BillingId == 1) .Where(x => x.BillingId == Convert.ToInt32(BillingType.Submitted)) .OrderByDescending(x => x.DateCreated). Take(5).ToList(); This - as far as my understanding is correct - is now using Linq to Objects rather than the Linq to SQL queries I was previously? Is this okay practise? It feels wrong to me but I dont know why. Probably because the logic of the queries is in the very highest tier of the app, rather than the lowest, but... I defer to you good people for advice. One of the issues I considered was bringing the entire table into memory but I understand that using the Iqeryable return type the where clause is taken to the database and evaluated there. Thus returning only the resultset i require... i may be wrong. And if you've made it this far, well done. Thank you, and if you have any advice it is very much appreciated!!

  • UIEvent for iPhone locking & unlocking?

    - by Jason
    I am building an iPhone app in which I want to time user activity. However, I don't want to count time when the iPhone was locked (or when the user received a phone call) when calculating the times. What is the best way to do this? Is there a UIEvent which my app can receive (and act upon) when the iPhone locks or unlocks?

  • ~saas license manager

    - by Steven
    Hi all, We're developing a saas app, which is almost finished. Being in the final stages we're wondering how we are going to charge customers for using our app, how we will enforce they will not pass on their logins and so on. Does anyone know a ready-made solution? We do have a budget for this. rough criteria: - enforcing multiple payment/licensing options (trial - license with grace periods, on demand, pay per use, etc) - integration with payment providers - tracking/preventing unauthorised usage - payment/license plans adjustable on a per customer(group) basis

  • UIView "suck" animation

    - by igul222
    I'd like to use the UIView "sucking" transition (view is "sucked" into a point) referenced here: http://iphonedevwiki.net/index.php/UIViewAnimationState#Using_suckEffect The method above, however, uses private APIs, which makes it next to useless for an App Store app. How can I recreate a similar effect without relying on private APIs? I'm guessing the answer has to do with OpenGL, although I have zero experience there.

  • Own framework on iPhone

    - by jaleel
    I created a framework for common tasks such as XML parsing, buttons and so on. Can I upload my application in App Store if it uses this framework? I saw somewhere that App Store did not support private frameworks. Is this a private framework, even though I created it using Apple's libraries, such as UIkit, Foundation, etc.?

  • How to check with program in other programming-language (C,C++, etc) whether JAVA is installed and w

    - by Andreas Hornig
    Hi, I would like to know whether or not JAVA is installed and where (path). Perhaps it sounds strange, but my aim is to let BOINC (coded in C++) check the JAVA installation and then start my JAVA app. But therefore I need to know if BOINC can start JAVA natively, or if I have to also send the JRE and then start my app with this not installed JRE. So is there a way to check the installation first? thank you in advance! Andreas

  • Are "EXC_BREAKPOINT (SIGTRAP)" exceptions caused by debugging breakpoints?

    - by Dennis
    I have a multithreaded app that is very stable on all my test machines and seems to be stable for almost every one of my users (based on no complaints of crashes). The app crashes frequently for one user, though, who was kind enough to send crash reports. All the crash reports (~10 consecutive reports) look essentially identical: Date/Time: 2010-04-06 11:44:56.106 -0700 OS Version: Mac OS X 10.6.3 (10D573) Report Version: 6 Exception Type: EXC_BREAKPOINT (SIGTRAP) Exception Codes: 0x0000000000000002, 0x0000000000000000 Crashed Thread: 0 Dispatch queue: com.apple.main-thread Thread 0 Crashed: Dispatch queue: com.apple.main-thread 0 com.apple.CoreFoundation 0x90ab98d4 __CFBasicHashRehash + 3348 1 com.apple.CoreFoundation 0x90adf610 CFBasicHashRemoveValue + 1264 2 com.apple.CoreText 0x94e0069c TCFMutableSet::Intersect(__CFSet const*) const + 126 3 com.apple.CoreText 0x94dfe465 TDescriptorSource::CopyMandatoryMatchableRequest(__CFDictionary const*, __CFSet const*) + 115 4 com.apple.CoreText 0x94dfdda6 TDescriptorSource::CopyDescriptorsForRequest(__CFDictionary const*, __CFSet const*, long (*)(void const*, void const*, void*), void*, unsigned long) const + 40 5 com.apple.CoreText 0x94e00377 TDescriptor::CreateMatchingDescriptors(__CFSet const*, unsigned long) const + 135 6 com.apple.AppKit 0x961f5952 __NSFontFactoryWithName + 904 7 com.apple.AppKit 0x961f54f0 +[NSFont fontWithName:size:] + 39 (....more text follows) First, I spent a long time investigating [NSFont fontWithName:size:]. I figured that maybe the user's fonts were screwed up somehow, so that [NSFont fontWithName:size:] was requesting something non-existent and failing for that reason. I added a bunch of code using [[NSFontManager sharedFontManager] availableFontNamesWithTraits:NSItalicFontMask] to check for font availability in advance. Sadly, these changes didn't fix the problem. I've now noticed that I forgot to remove some debugging breakpoints, including _NSLockError, [NSException raise], and objc_exception_throw. However, the app was definitely built using "Release" as the active build configuration. I assume that using the "Release" configuration prevents setting of any breakpoints--but then again I am not sure exactly how breakpoints work or whether the program needs to be run from within gdb for breakpoints to have any effect. My questions are: could my having left the breakpoints set be the cause of the crashes observed by the user? If so, why would the breakpoints cause a problem only for this one user? If not, has anybody else had similar problems with [NSFont fontWithName:size:]? I will probably just try removing the breakpoints and sending back to the user, but I'm not sure how much currency I have left with that user. And I'd like to understand more generally whether leaving the breakpoints set could possibly cause a problem (when the app is built using "Release" configuration).

  • javascript detect if being run in hta

    - by rjmunro
    We'd like to allow our users to download an hta file and run our web app inside it, and have certain pages detect that they are running in an hta file and offer additional features that a web app wouldn't normally have permission to do. How can I simply detect if the page is being browsed from an hta file container?

  • Javascript Sandbox

    - by Louis
    I want to have developers write some custom apps for a site in Javascript but I want to sandbox it so they can't do anything naughty like redirect the user, set the body display to none etc etc. I have a namespace in Javascript where all the functions they'll ever need exist in there so I was thinking to create a sandbox would be a matter of: with(Namespace) { //App code goes here where they can only access Namespace.* } How is easy is it to get around this and what other methods can be done? Would rather not have to moderate every submitted app.

  • Android - Playing Mp4

    - by Chris
    I am trying to play video files from http urls in my app. Why is that my app plays only certain mp4 files (I tried 512k mp4 and it worked), and doesn't play some others? Here's the snippet of my code: mVideoView.setVideoPath(myVideoURL); mVideoView.setMediaController(new MediaController(this)); mVideoView.seekTo(currentPosition); mVideoView.requestFocus(); Thanks Chris

  • WCF: 'Update Service Reference' hoses my files.

    - by mcoolbeth
    Every time that I make a change to the contract of my WCF service, I need to have Visual Studio update the service references in all of my client projects. This process regenerates my client's app.config file and, since I have hand-tuned the "bindings" section of the file, I need to back-up my file and then restore it each time I have VS do the update. Is there a way to avoid this necessity (eg: have VS update the service reference without rewriting anything in app.config)? Thanks

  • Strong name, Manifest, and Code Signing

    What order should these be done in? I'm doing this from the command prompt for a .Net app. I was able to do just strong name and code signing successfully, but when I tried all three, it doesn't look like it worked (== Vista still trying to run the app with elevated privileges resulting in a prompt, though I set the requestedexecutionlevel at asInvoker) Thanks in advance

  • json-framework error in iPhone static library

    - by David Beck
    I have an iPhone app that uses the json-framework. I moved some of the code, including the json-framework source, from the main project to a static library. When I did this, the json-framework stopped getting compiled into the binary (double checked with class dump). This causes a nasty error: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFString JSONValue]: unrecognized selector sent to instance 0x43897f0' Everything else in the static library continues to function properly.

  • Freetype2 failing under WoW64

    - by Necrolis
    I built a tff to D3D texture function using freetype2(2.3.9) to generate grayscale maps from the fonts. it works great under native win32, however, on WoW64 it just explodes (well, FT_Done and FT_Load_Glyph do). from some debugging, it seems to be a problem with HeapFree as called by free from FT_Free. I know it should work, as games like WCIII, which to the best of my knowledge use freetype2, run fine, this is my code, stripped of the D3D code(which causes no problems on its own): FT_Face pFace = NULL; FT_Error nError = 0; FT_Byte* pFont = static_cast<FT_Byte*>(ARCHIVE_LoadFile(pBuffer,&nSize)); if((nError = FT_New_Memory_Face(pLibrary,pFont,nSize,0,&pFace)) == 0) { FT_Set_Char_Size(pFace,nSize << 6,nSize << 6,96,96); for(unsigned char c = 0; c < 95; c++) { if(!FT_Load_Glyph(pFace,FT_Get_Char_Index(pFace,c + 32),FT_LOAD_RENDER)) { FT_Glyph pGlyph; if(!FT_Get_Glyph(pFace->glyph,&pGlyph)) { LOG("GET: %c",c + 32); FT_Glyph_To_Bitmap(&pGlyph,FT_RENDER_MODE_NORMAL,0,1); FT_BitmapGlyph pGlyphMap = reinterpret_cast<FT_BitmapGlyph>(pGlyph); FT_Bitmap* pBitmap = &pGlyphMap->bitmap; const size_t nWidth = pBitmap->width; const size_t nHeight = pBitmap->rows; //add to texture atlas } } } } else { FT_Done_Face(pFace); delete pFont; return FALSE; } FT_Done_Face(pFace); delete pFont; return TRUE; } ARCHIVE_LoadFile returns blocks allocated with new. As a secondary question, I would like to render a font using pixel sizes, I came across FT_Set_Pixel_Sizes, but I'm unsure as to whether this stretches the font to fit the size, or bounds it to a size. what I would like to do is render all the glyphs at say 24px (MS Word size here), then turn it into a signed distance field in a 32px area. Update After much fiddling, I got a test app to work, which leads me to think the problems are arising from threading, as my code is running in a secondary thread. I have compiled freetype into a static lib using the multithread DLL, my app uses the multithreaded libs. gonna see if i can set up a multithreaded test. Also updated to 2.4.4, to see if the problem was a known but fixed bug, didn't help however. Update 2 After some more fiddling, it turns out I wasn't using the correct lib for 2.4.4 -.- after fixing that, the test app works 100%, but the main app still crashes when FT_Done_Face is called, still seems to be a crash in the memory heap management of windows. is it possible that there is a bug in freetype2 that makes it blow up under user threads?
