  • Convert MSAccess Project Management Application to PHP/MySQL: Which Methodology?

    - by zzapper
    I've got to convert a not terribly complicated bespoke project management system from MsAccess Application to PHP/MySQL. I've been programming for donkey's years but embarrassingly know practically nothing about modern methodologies. So the old 'learning curve' versus 'improved efficiency' conundrum rears its ugly head once again. Although I've Googled up some stuff I don't want to prejudice your suggestions, where would you start, I'm at your mercy?

  • How can I compile a GUI executable with ghc?

    - by martingw
    I ported a little Haskell program I wrote from Mac to Windows. It's a GUI application (wxHaskell, compiled with ghc 6.12.1), so it does not need the command prompt window to open. It does so, anyway, so my question: What must I do so that the program starts without opening a prompt window first? Is there some ghc switch for this?

  • How to install gem from GitHub source?

    - by Vojto
    Hello, I know this is probably kind of noob question, but I never tried this before and I'm not sure how to do this. So when I installed my gem with gem utility it installed too old version. I want latest version, that is on GitHub. I could just download source, but I want to be able to load with gem in my Ruby code. Any ideas?

  • Bizarre WHERE col = NULL behavior

    - by Kenneth
    This is a problem one of our developers brought to me. He stumbled across an old stored procedure which used 'WHERE col = NULL' several times. When the stored procedure is executed it returns data. If the query inside the stored procedure is executed manually it will not return data unless the 'WHERE col = NULL' references are changed to 'WHERE col IS NULL'. Can anyone explain this behavior?

  • What is the proper way to do a Subversion merge in Eclipse?

    - by awied
    I'm pretty used to how to do CVS merges in Eclipse, and I'm otherwise happy with the way that both Subclipse and Subversive work with the SVN repository, but I'm not quite sure how to do merges properly. When I do a merge, it seems to want to stick the merged files in a seperate directory in my project rather than overwriting the old files that are to be replaced in the merge, as I am used to in CVS. The question is not particular to either Subclipse or Subversive. Thanks for the help!

  • IIS 7.5 receive emails?

    - by Cine
    In the good old days with IIS 6, it was possible to use the SEOLib to make a managed hook in the SMTP service that would run whenever a mail got delivered. In Vista and W7 they stopped shipping SEOLib, so we can no longer develop for it. What is the replacement for this functionality?

  • Simple 301 redirect; how do I get it to drop the query string?

    - by Throlkim
    Hopefully there's a simple solution to this. I'm setting up a redirect for old search listings, but I don't want any of the query string to carry over. The current rule is: redirect 301 /blog http://newdomain.com But this would redirect the following: http://www.olddomain.com/blog/2009/11/article-name-etc To this: http://newdomain.com/2009/11/article-name-etc When I just want: http://newdomain.com Can this be done in the simple 301 redirect, or will I have to write a mod_rewrite rule?

  • PHP Session Class and $_SESSION Array

    - by Gianluca Bargelli
    Hello, i've implemented this custom PHP Session Class for storing sessions into a MySQL database: class Session { private $_session; public $maxTime; private $database; public function __construct(mysqli $database) { $this->database=$database; $this->maxTime['access'] = time(); $this->maxTime['gc'] = get_cfg_var('session.gc_maxlifetime'); session_set_save_handler(array($this,'_open'), array($this,'_close'), array($this,'_read'), array($this,'_write'), array($this,'_destroy'), array($this,'_clean') ); register_shutdown_function('session_write_close'); session_start();//SESSION START } public function _open() { return true; } public function _close() { $this->_clean($this->maxTime['gc']); } public function _read($id) { $getData= $this->database->prepare("SELECT data FROM Sessions AS Session WHERE Session.id = ?"); $getData->bind_param('s',$id); $getData->execute(); $allData= $getData->fetch(); $totalData = count($allData); $hasData=(bool) $totalData >=1; return $hasData ? $allData['data'] : ''; } public function _write($id, $data) { $getData = $this->database->prepare("REPLACE INTO Sessions VALUES (?, ?, ?)"); $getData->bind_param('sss', $id, $this->maxTime['access'], $data); return $getData->execute(); } public function _destroy($id) { $getData=$this->database->prepare("DELETE FROM Sessions WHERE id = ?"); $getData->bind_param('S', $id); return $getData->execute(); } public function _clean($max) { $old=($this->maxTime['access'] - $max); $getData = $this->database->prepare("DELETE FROM Sessions WHERE access < ?"); $getData->bind_param('s', $old); return $getData->execute(); } } It works well but i don't really know how to properly access the $_SESSION array: For example: $db=new DBClass();//This is a custom database class $session=new Session($db->getConnection()); if (isset($_SESSION['user'])) { echo($_SESSION['user']);//THIS IS NEVER EXECUTED! } else { $_SESSION['user']="test"; Echo("Session created!"); } At every page refresh it seems that $_SESSION['user'] is somehow "resetted", what methods can i apply to prevent such behaviour?

  • TeamCity build number independent artifacts

    - by Stanislav Shevchenko
    Hello, My TeamCity's nightly build produces more than 130Mb java doc as Build Configuration artifact. I have to share these artifact for other teams(developers), but javadoc every time has another one URL(I know that it's possible to get it like .lastFinished), and get's new place on Build Machine. Is it possible on each build replace old artifact with new one because I don't need need previous versions? And have independent from build version URL for accessing.

  • Is it reasonable to use OpenGL for desktop applications?

    - by JamesK89
    I've been writing a small desktop gadget-type application that displays scrolling text along the bottom of the screen (Similar to the old CNN news ticker), however the performance of GDI is just unsatisfactory (As high as 8-12% on a quad core and 20% on a single core) even after I've attempted to clean out bottlenecks. I was considering using OpenGL instead to render everything, but I don't know if that is a reasonable option to require users to have hardware acceleration for a tiny app like this. Does anybody have any input on this?

  • Using Core Data Concurrently and Reliably

    - by John Topley
    I'm building my first iOS app, which in theory should be pretty straightforward but I'm having difficulty making it sufficiently bulletproof for me to feel confident submitting it to the App Store. Briefly, the main screen has a table view, upon selecting a row it segues to another table view that displays information relevant for the selected row in a master-detail fashion. The underlying data is retrieved as JSON data from a web service once a day and then cached in a Core Data store. The data previous to that day is deleted to stop the SQLite database file from growing indefinitely. All data persistence operations are performed using Core Data, with an NSFetchedResultsController underpinning the detail table view. The problem I am seeing is that if you switch quickly between the master and detail screens several times whilst fresh data is being retrieved, parsed and saved, the app freezes or crashes completely. There seems to be some sort of race condition, maybe due to Core Data importing data in the background whilst the main thread is trying to perform a fetch, but I'm speculating. I've had trouble capturing any meaningful crash information, usually it's a SIGSEGV deep in the Core Data stack. The table below shows the actual order of events that happen when the detail table view controller is loaded: Main Thread Background Thread viewDidLoad Get JSON data (using AFNetworking) Create child NSManagedObjectContext (MOC) Parse JSON data Insert managed objects in child MOC Save child MOC Post import completion notification Receive import completion notification Save parent MOC Perform fetch and reload table view Delete old managed objects in child MOC Save child MOC Post deletion completion notification Receive deletion completion notification Save parent MOC Once the AFNetworking completion block is triggered when the JSON data has arrived, a nested NSManagedObjectContext is created and passed to an "importer" object that parses the JSON data and saves the objects to the Core Data store. The importer executes using the new performBlock method introduced in iOS 5: NSManagedObjectContext *child = [[NSManagedObjectContext alloc] initWithConcurrencyType:NSPrivateQueueConcurrencyType]; [child setParentContext:self.managedObjectContext]; [child performBlock:^{ // Create importer instance, passing it the child MOC... }]; The importer object observes its own MOC's NSManagedObjectContextDidSaveNotification and then posts its own notification which is observed by the detail table view controller. When this notification is posted the table view controller performs a save on its own (parent) MOC. I use the same basic pattern with a "deleter" object for deleting the old data after the new data for the day has been imported. This occurs asynchronously after the new data has been fetched by the fetched results controller and the detail table view has been reloaded. One thing I am not doing is observing any merge notifications or locking any of the managed object contexts or the persistent store coordinator. Is this something I should be doing? I'm a bit unsure how to architect this all correctly so would appreciate any advice.

  • @ in p4 filename

    - by Denise
    I'd like to script p4 a little. Unfortunately, some of the filenames that we're tracking have "@" in the filename. The filenames are in the form [email protected]. If I try to do something like p4 sync a\@b.xml on a mac (or p4 sync [email protected] on windows) it gives the error: Invalid changelist/client/label/date '@b.xml' Is there another way to escape it that perforce will recognize?
