  • Inconsistent get_class_methods vs method_exists when using UTF8 characters in PHP code

    - by coma
    I have this class in a UTF-8 encoded file called EnUTF8.Class.php: class EnUTF8 { public function ñññ() { return 'ñññ()'; } } and in another UTF-8 encoded file: require_once('EnUTF8.Class.php'); require_once('OneBuggy.Class.php'); $utf8 = new EnUTF8(); //$buggy = new OneBuggy(); echo (method_exists($utf8, 'ñññ')) ? 'ñññ() exists!' : 'ñññ() does not exist...'; echo "\n\n----------------------------------\n\n" print_r(get_class_methods($utf8)); echo "\n----------------------------------\n\n" echo $utf8->ñññ(); that produces the expected result: ñññ() exists! ---------------------------------- Array ( [0] => ñññ ) ---------------------------------- ñññ() but if... require_once('EnUTF8.Class.php'); require_once('OneBuggy.Class.php'); $utf8 = new EnUTF8(); $buggy = new OneBuggy(); echo (method_exists($utf8, 'ñññ')) ? 'ñññ() exists!' : 'ñññ() does not exist...'; echo "\n\n----------------------------------\n\n" print_r(get_class_methods($utf8)); echo "\n----------------------------------\n\n" echo $utf8->ñññ(); then the weirdness appears!!!: ñññ() does not exist! ---------------------------------- Array ( [0] => ñññ ) ---------------------------------- Fatal error: Call to undefined method EnUTF8::ñññ() in /var/www/test.php on line 16 Well, the thing is that OneBuggy.Class.php is UTF-8 encoded too and shares absolutly nothing with EnUTF8.Class.php so... where is the bug? UPDATED: Well, after a long debugging time I found this in OneBuggy.Class.php constructor: setlocale (LC_ALL, "es_ES@euro", "es_ES", "esp"); so I did... //setlocale (LC_ALL, "es_ES@euro", "es_ES", "esp"); and now it works but why?.

  • Instantiating class with custom allocator in shared memory

    - by recipriversexclusion
    I'm pulling my hair due to the following problem: I am following the example given in boost.interprocess documentation to instantiate a fixed-size ring buffer buffer class that I wrote in shared memory. The skeleton constructor for my class is: template<typename ItemType, class Allocator > SharedMemoryBuffer<ItemType, Allocator>::SharedMemoryBuffer( unsigned long capacity ){ m_capacity = capacity; // Create the buffer nodes. m_start_ptr = this->allocator->allocate(); // allocate first buffer node BufferNode* ptr = m_start_ptr; for( int i = 0 ; i < this->capacity()-1; i++ ) { BufferNode* p = this->allocator->allocate(); // allocate a buffer node } } My first question: Does this sort of allocation guarantee that the buffer nodes are allocated in contiguous memory locations, i.e. when I try to access the n'th node from address m_start_ptr + n*sizeof(BufferNode) in my Read() method would it work? If not, what's a better way to keep the nodes, creating a linked list? My test harness is the following: // Define an STL compatible allocator of ints that allocates from the managed_shared_memory. // This allocator will allow placing containers in the segment typedef allocator<int, managed_shared_memory::segment_manager> ShmemAllocator; //Alias a vector that uses the previous STL-like allocator so that allocates //its values from the segment typedef SharedMemoryBuffer<int, ShmemAllocator> MyBuf; int main(int argc, char *argv[]) { shared_memory_object::remove("MySharedMemory"); //Create a new segment with given name and size managed_shared_memory segment(create_only, "MySharedMemory", 65536); //Initialize shared memory STL-compatible allocator const ShmemAllocator alloc_inst (segment.get_segment_manager()); //Construct a buffer named "MyBuffer" in shared memory with argument alloc_inst MyBuf *pBuf = segment.construct<MyBuf>("MyBuffer")(100, alloc_inst); } This gives me all kinds of compilation errors related to templates for the last statement. What am I doing wrong?

  • Menu items messed up while using MacVim with Vim Latex

    - by sixtyfootersdude
    I just installed macvim yesterday and I have been trying to install vim latex today. The one thing I am confused about is the menu items on the top bar: ------------------------------------------------------------------------------- <apple icon> File Edit Tools Syntax TeX-Suite TeX-Environments TeX-Elements ------------------------------------------------------------------------------- | Packages > |_____ | Templates > | 1: | | Macros > | 2: | |----------- | 3: | | Compile | 4: | | View |----- | ... | ------------- So in words if you go TeX-Suite -> Templates there is a sub menu with menu items: 1: 2: 3: 4:. Now I know that these templates live here: % pwd /Users/me/.vim/ftplugin/latex-suite/templates % ls IEEEtran.tex article.tex report.tex report_two_column.tex and they are named correctly. Also I know that the :TTemplate vim command should do the same thing. When I type that I get this result: Choose a template file: (1) IEEEtran (2) article (3) report (4) report_two_column Enter number or name of file : So I am thinking that this must be a bug in MacVim. Is this a reasonable assumption? Any fixes?

  • How do you create a non-Thread-based Guice custom Scope?

    - by Russ
    It seems that all Guice's out-of-the-box Scope implementations are inherently Thread-based (or ignore Threads entirely): Scopes.SINGLETON and Scopes.NO_SCOPE ignore Threads and are the edge cases: global scope and no scope. ServletScopes.REQUEST and ServletScopes.SESSION ultimately depend on retrieving scoped objects from a ThreadLocal<Context>. The retrieved Context holds a reference to the HttpServletRequest that holds a reference to the scoped objects stored as named attributes (where name is derived from com.google.inject.Key). Class SimpleScope from the custom scope Guice wiki also provides a per-Thread implementation using a ThreadLocal<Map<Key<?>, Object>> member variable. With that preamble, my question is this: how does one go about creating a non-Thread-based Scope? It seems that something that I can use to look up a Map<Key<?>, Object> is missing, as the only things passed in to Scope.scope() are a Key<T> and a Provider<T>. Thanks in advance for your time.

  • Creative ways to punish (or just curb) laziness in coworkers

    - by FerretallicA
    Like the subject suggests, what are some creative ways to curb laziness in co-workers? By laziness I'm talking about things like using variable names like "inttheemplrcd" instead of "intEmployerCode" or not keeping their projects synced with SVN, not just people who use the last of the sugar in the coffee room and don't refill the jar. So far the two most effective things I've done both involve the core library my company uses. Since most of our programs are in VB.net the lack of case sensitivity is abused a lot. I've got certain features of the library using Reflection to access data in the client apps, which has a negligible performance hit and introduces case sensitivity in a lot places where it is used. In instances where we have an agreed standard which is compromised by blatant laziness I take it a step further, like the DatabaseController class which will blatantly reject any DataTable passed to it which isn't named dtSomething (ie- must begin with dt and third letter must be capitalised). It's frustrating to have to resort to things like this but it has also gradually helped drill more attention to detail into their heads. Another is adding some code to the library's initialisation function to display a big and potentially embarrassing (only if seen by a client) message advising that the program is running in debug mode. We have had many instances where projects are sent to clients built in debug mode which has a lot of implications for us (especially with regard to error recovery) and doing that has made sure they always build to release before distributing. Any other creative (ie- not StyleCop etc) approaches like this?

  • PHP XML Strategy: Parsing DOM to fill "Bean"

    - by Mike
    I have a question concerning a good strategy on how to fill a data "bean" with data inside an xml file. The bean might look like this: class Person { var $id; var $forename = ""; var $surname = ""; var $bio = new Biography(); } class Biography { var $url = ""; var $id; } the xml subtree containing the info might look like this: <root> <!-- some more parent elements before node(s) of interest --> <person> <name pre="forename"> Foo </name> <name pre="surname"> Bar </name> <id> 1254 </id> <biography> <url> http://www.someurl.com </url> <id> 5488 </id> </biography> </person> </root> At the moment, I have one approach using DOMDocument. A method iterates over the entries and fills the bean by "remembering" the last node. I think thats not a good approach. What I have in mind is something like preconstructing some xpath expression(s) and then iterate over the subtrees/nodeLists. Return an array containing the beans as defined above eventually. However, it seems not to be possible reusing a subtree /DOMNode as DOMXPath constructor parameter. Has anyone of you encountered such a problem?

  • Android: how to tell if a view is scrolling

    - by Dave
    in iPhone, this would be simple---each view has a scrollViewDidScroll method. I am trying to find the equivalent in Android. My code works, but it isn't giving me what I want. I need to execute code the entire duration that a view is scrolling. So, even though I use OnGestureListener's onScroll method, it only fires when the finger is on the screen (it's not really named correctly---it should be called "onSlide" or "onSwipe", focusing on the gesture rather than the UI animation). It does not continue to fire if the user flicks the view and it is still scrolling for a few moments after the user lifts his finger. is there a method that is called at every step of the scroll? public class Scroll extends Activity implements OnGestureListener { public WebView webview; public GestureDetector gestureScanner; public int currentYPosition; public int lastYPosition; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); webview = new WebView(this); setContentView(webview); webview.loadUrl("file:///android_asset/Scroll.html"); gestureScanner = new GestureDetector(this); currentYPosition = 0; lastYPosition = 0; } public boolean onTouchEvent(final MotionEvent me) { return gestureScanner.onTouchEvent(me); } public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { // I do stuff here. return true; }

  • HttpModule.Init - safely add HttpApplication.BeginRequest handler in IIS7 integrated mode

    - by Paul Smith
    My question is similar but not identical to: http://stackoverflow.com/questions/1123741/why-cant-my-host-softsyshosting-com-support-beginrequest-and-endrequest-event (I've also read the mvolo blog referenced therein) The goal is to successfully hook HttpApplication.BeginRequest in the IHttpModule.Init event (or anywhere internal to the module), using a normal HttpModule integrated via the system.webServer config, i.e. one that doesn't: invade Global.asax or override the HttpApplication (the module is intended to be self-contained & reusable, so e.g. I have a config like this): <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <modules> <remove name="TheHttpModule" /> <add name="TheHttpModule" type="Company.HttpModules.TheHttpModule" preCondition="managedHandler" /> So far, any strategy I've tried to attach a listener to HttpApplication.BeginRequest results in one of two things, symptom 1 is that BeginRequest never fires, or symptom 2 is that the following exception gets thrown on all managed requests, and I cannot catch & handle it from user code: Stack Trace: [NullReferenceException: Object reference not set to an instance of an object.] System.Web.PipelineModuleStepContainer.GetEventCount(RequestNotification notification, Boolean isPostEvent) +30 System.Web.PipelineStepManager.ResumeSteps(Exception error) +1112 System.Web.HttpApplication.BeginProcessRequestNotification(HttpContext context, AsyncCallback cb) +113 System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +616 Commenting out app.BeginRequest += new EventHandler(this.OnBeginRequest) in Init stops the exception of course. Init does not reference the Context or Request objects at all. I have tried: Removed all references to HttpContext.Current anywhere in the project (still symptom 1) Tested removing all code from the body of my OnBeginRequest method, to ensure the problem wasn't internal to the method (= exception) Sniffing the stack trace and only calling app.BeginRequest+=... when if the stack isn't started by InitializeApplication (= BeginRequest not firing) Only calling app.BeginRequest+= on the second pass through Init (= BeginRequest not firing) Anyone know of a good approach? Is there some indirect strategy for hooking Application_Start within the module (seems unlikely)? Another event which a) one can hook from a module's constructor or Init method, and b) which is subsequently a safe place to attach BeginRequest event handlers? Thanks much

  • Differences between iPhone/iPod Simulator and Devices

    - by Allisone
    Hi, since I started iPhone/iPod Development I have come across some differences between how the simulator and how real device react. Maybe I will come across some other differences I will have to figure out as well, maybe other people haven't met these problems here (YET) and can profit from the knowledge, and maybe you know some problems/differences that you would have been happy to know about earlier before you spent several hours or days figuring out what the heck is going on. So here is what I came across. Simulator is not case sensitive, Devices are case sensitive. This means a default.png or Icon.png will work in simulator, but not on a device where they must be named Default.png and icon.png (if it's still not working read this answer) Simulator has different codecs to play audio and video If you use f.e. MPMoviePlayerController you might play certain video on the simulator while on the device it won't work (use Handbrake-presets-iPhone & iPod Touch to create playable videos for Simulator and Device). If you play audio with AudioServicesPlaySystemSound(&soundID) you might here the sound on simulator but not an a device. (use Audacity to open your soundfile, export as wav and run afconvert -f caff -d LEI16@44100 -c 1 audacity.wav output.caf in terminal) Also there is this flickering on second run problem which can be resolved with an playerViewCtrl.initialPlaybackTime = -1.0; either on the end of playing or before each beginning. Simulator is mostly much faster cause it doesn't simulate the hardware but uses Mac resources, therefore f.e. sio2 Apps (OpenGL,OpenAL,etc. framework) run much better on simulator, well everything that uses more resources will run visibly better in simulator than on device. I hope we can add some more to this.

  • SQL database problems with addressbook table design

    - by Sebastian Hoitz
    Hello! I am writing a addressbook module for my software right now. I have the database set up so far that it supports a very flexible address-book configuration. I can create n-entries for every type I want. Type means here data like 'email', 'address', 'telephone' etc. I have a table named 'contact_profiles'. This only has two columns: id Primary key date_created DATETIME And then there is a table called contact_attributes. This one is a little more complex: id PK #profile (Foreign key to contact_profiles.id) type VARCHAR describing the type of the entry (name, email, phone, fax, website, ...) I should probably change this to a SET later. value Text (containing the value for the attribute). I can now link to these profiles, for example from my user's table. But from here I run into problems. At the moment I would have to create a JOIN for each value that I want to retrieve. Is there a possibility to somehow create a View, that gives me a result with the type's as columns? So right now I would get something like #profile type value 1 email [email protected] 1 name Sebastian Hoitz 1 website domain.tld But it would be nice to get a result like this: #profile email name website 1 [email protected] Sebastian Hoitz domain.tld The reason I do not want to create the table layout like this initially is, that there might always be things to add and I want to be able to have multiple attributes of the same type. So do you know if there is any possibility to convert this dynamically? If you need a better description please let me know. Thank you!

  • General N-Tier Architecture Question

    - by whatispunk
    In an N-Tier app you're supposed to have a business logic layer and a data access layer. Is it bad to simply have two assemblies: BusinessLogicLayer.dll and DataAccessLayer.dll to handle all this logic? How do you actually represent these layers. It seems silly, the way I've seen it, to have a BusinessLogic class library containing classes like: CustomerBusinessLogic.cs, OrderBusinessLogic.cs, etc. each calling their appropriately named cousin in the DataAccessLayer class library, i.e. CustomerDataAccess.cs, OrderDataAccess.cs. I want to create a web app using MVP and it doesn't seem so cut and dry as this. There are lots of opinions about where the business logic is supposed to be put in MVP and I'm not sure I've found a really great answer yet. I want this project to be easily testable, and I am trying to adhere to TDD methodologies as best I can. I intend to use MSTest and Rhino Mocks for testing. I was thinking of something like the following for my architecture: I'd use LINQ-To-SQL to talk to the database. WCF services to define data contract interfaces for the business logic layer. Then use MVP with ASP.NET Forms for the UI/BLL. Now, this isn't the start of this project, most of the LINQ stuff is already done, so its stuck. The WCF service would replace the existing DataAccessLayer assembly and the UI/BLL would replace the BusinessLogicLayer assembly etc. This sort of makes sense in my head, but its getting really late. Anyone that's traveled down this path have any guidance? Good links? Warnings? Thanks!

  • Database migration pattern for Java?

    - by Eno
    Im working on some database migration code in Java. Im also using a factory pattern so I can use different kinds of databases. And each kind of database im using implements a common interface. What I would like to do is have a migration check that is internal to the class and runs some database schema update code automatically. The actual update is pretty straight forward (I check schema version in a table and compare against a constant in my app to decide whether to migrate or not and between which versions of schema). To make this automatic I was thinking the test should live inside (or be called from) the constructor. OK, fair enough, that's simple enough. My problem is that I dont want the test to run every single time I instantiate a database object (it runs a query so having it run on every construction is not efficient). So maybe this should be a class static method? I guess my question is, what is a good design pattern for this type of problem? There ought to be a clean way to ensure the migration test runs only once OR is super-efficient.

  • Firefox extension development firefox4

    - by Jesus Ramos
    So I've been working on updating old extensions for use with FF4 and Gecko 2 but I am having some issues where I am getting an error that says, classID missing or incorrect for component.... Has anyone else had a similar issue or know of how to get around this? function jsshellClient() { this.classDescription = "sdConnector JavaScript Shell Service"; this.classID = Components.ID("{54f7f162-35d9-524d-9021-965a3ba86366}"); this.contractID = "@activestate.com/SDService?type=jsshell;1" this._xpcom_categories = [{category: "sd-service", entry: "jsshell"}]; this.name = "jsshell"; this.prefs = Components.classes["@mozilla.org/preferences-service;1"] .getService(Components.interfaces.nsIPrefService) .getBranch("sdconnector.jsshell."); this.enabled = this.prefs.getBoolPref("enabled"); this.port = this.prefs.getIntPref("port"); this.loopbackOnly = this.prefs.getBoolPref("loopbackOnly"); this.backlog = this.prefs.getIntPref("backlog"); } jsshellClient.prototype = new session(); jsshellClient.prototype.constructor = jsshellClient; When calling generateNSGetFactory on the prototype for this it gives an error in the Error Console in FF4 complaining about the classID. I'm pretty sure that nothing else is using the same GUID so I don't see the problem.

  • No test coverage files generated for Unit Test bundle in Xcode

    - by John Gallagher
    The Problem I've got a Cocoa project on the desktop and I'm using Xcode 3.2.1 on Snow Leopard 10.6.2. I want to generate code coverage files for my Unit Test Target in Xcode. What I've Tried As articles like this one suggest, I've adjusted the build settings to: “Generate Test Coverage Files” checked “Instrument Program Flow” checked “-lgcov” added to “Other Linker Flags” I've also set the Run Script section of the test target to have the following: # Run the unit tests in this test bundle. "${SYSTEM_DEVELOPER_DIR}/Tools/RunUnitTests" # Run gcov on the framework getting tested if [ "${CONFIGURATION}" = 'Coverage' ]; then FRAMEWORK_NAME=LapsusInterpretationEngine FRAMEWORK_OBJ_DIR=${OBJROOT}/${FRAMEWORK_NAME}.build/${CONFIGURATION}/EngineTests.build/Objects-normal/${NATIVE_ARCH} mkdir -p coverage pushd coverage find ${OBJROOT} -name *.gcda -exec gcov -o ${FRAMEWORK_OBJ_DIR} {} \; popd fi Since my Framework name is LapsusInterpretationEngine but my target is named EngineTests, I put this directly into the FRAMEWORK_OBJ_DIR but this didn't seem to help. I've tried cleaning before building. I've made sure all the above build settings apply to both the Unit Test Target and the Application Target. What I Get No .gcda or .gcno files anywhere in the build directory I'm using. I point CoverStory to the Objects-normal directory in my builds folder and it complains that there's nothing there for it to read. I must be doing something really obvious wrong. Anyone any ideas? I have tried the "EngineTests.build" directory being ${FRAMEWORK_NAME} and this gives the same results.

  • JVM/CLR Source-compatible Language Options

    - by Nathan Voxland
    I have an open source Java database migration tool (http://www.liquibase.org) which I am considering porting to .Net. The majority of the tool (at least from a complexity side) is around logic like "if you are adding a primary key and the database is Oracle use this SQL. If database is MySQL use this SQL. If the primary key is named and the database is Postgres use this SQL". I could fork the Java codebase and covert it (manually and/or automatically), but as updates and bug fixes to the above logic come in I do not want to have to apply it to both versions. What I would like to do is move all that logic into a form that can be compiled and used by both Java and .Net versions naively. The code I am looking to convert does not contain any advanced library usage (JDBC, System.out, etc) that would vary significantly from Java to .Net, so I don't think that will be an issue (at worst it can be designed around). So what I am looking for is: A language in which I can code common parts of my app in and compile it into classes usable by the "standard" languages on the target platform Does not add any runtime requirements to the system Nothing so strange that it scares away potential contributors I know Python and Ruby both have implementations on for the JVM and CLR. How well do they fit my requirements? Has anyone been successful (or unsuccesful) using this technique for cross-platform applications? Are there any gotcha's I need to worry about?

  • Passing viewmodel to actionresult creates new viewmodel

    I am using a viewmodel, which i then when to send to an actionresult to use (the modified viewmodel) But in the controller, i lose the list and objects in my viewmodel.

  • Core Data 1-to-many relationship: List all related objects as section header in UITableView

    - by Snej
    Hi: I struggle with Core Data on the iPhone about the following: I have a 1-to-many relationship in Core Data. Assume the entities are called recipe and category. A category can have many recipes. I accomplished to get all recipes listed in a UITableView with section headers named after the category. What i want to achieve is to list all categories as section header, even those which have no recipe: category1 <--- this one should be displayed too category2 recipe_x recipe_y category3 recipe_z NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Recipe" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; [fetchRequest setFetchBatchSize:10]; NSSortDescriptor *sortDescriptor1 = [[NSSortDescriptor alloc] initWithKey:@"category.categoryName" ascending:YES]; NSSortDescriptor *sortDescriptor2 = [[NSSortDescriptor alloc] initWithKey:@"recipeName" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor1,sortDescriptor2, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"category.categoryName" cacheName:@"Recipes"]; What is the most elegant way to achieve this with core data?

  • iPhone: addAnnotation not working when called from another view

    - by Nic Hubbard
    I have two views, the first view has an MKMapView on it named ridesMap. The second view is just a view with a UITableView in it. When you click the save button in the second view, it calls a method from the first view: // Get my first views class MyRidesMapViewController *rideMapView = [[MyRidesMapViewController alloc] init]; // Call the method from my first views class that removes an annotation [rideMapView addAnno:newRidePlacemark.coordinate withTitle:rideTitle.text withSubTitle:address]; This correctly calls the addAnno method, which looks like: - (void)addAnno:(CLLocationCoordinate2D)anno withTitle:(NSString *)annoTitle withSubTitle:(NSString *)subTitle { Annotation *ano = [[[Annotation alloc] init] autorelease]; ano.coordinate = anno; ano.title = annoTitle; ano.subtitle = subTitle; if ([ano conformsToProtocol:@protocol(MKAnnotation)]) { NSLog(@"YES IT DOES!!!"); } [ridesMap addAnnotation:ano]; }//end addAnno This method creates an annotation which does conform to MKAnnotation, and it suppose to add that annotation to the map using the addAnnotation method. But, the annotation never gets added. I NEVER get any errors when the annotation does not get added. But it never appears when the method is called. Why would this be? It seems that I have done everything correctly, and that I am passing a correct MKAnnotation to the addAnnotation method. So, I don't get why it never drops a pin? Could it be because I am calling this method from another view? Why would that matter?

  • rename files with the same name

    - by snorpey
    Hi. I use the following function to rename thumbnails. For example, if I upload a file called "image.png" to an upload folder, and this folder already has a file named "image.png" in it, the new file automatically gets renamed to "image-copy-1.png". If there also is a file called "image-copy-1.png" it gets renamed to "image-copy-2.png" and so on. The following function returns the new filename. At least that's what it is supposed to do... The renaming doesn't seeem to work correctly, though. Sometimes it produces strange results, like: 1.png 1-copy-1.png 1-copy-2.png 1-copy-2-copy-1.png 1-copy-2-copy-3.png I hope you understand my problem, despite my description being somewhat complex... Can you tell me what went wrong here? (bonus question: Is regular expressions the right tool for doing this kind of stuff?) <?php function renameDuplicates($path, $file) { $fileName = pathinfo($path . $file, PATHINFO_FILENAME); $fileExtension = "." . pathinfo($path . $file, PATHINFO_EXTENSION); if(file_exists($path . $file)) { $fileCopy = $fileName . "-copy-1"; if(file_exists($path . $fileCopy . $fileExtension)) { if ($contains = preg_match_all ("/.*?(copy)(-)(\\d+)/is", $fileCopy, $matches)) { $copyIndex = $matches[3][0]; $fileName = substr($fileCopy, 0, -(strlen("-copy-" . $copyIndex))) . "-copy-" . ($copyIndex + 1); } } else { $fileName .= "-copy-1"; } } $returnValue = $fileName . $fileExtension; return $returnValue; }?>

  • Visual Studio 2005 - OleDbConnection throws "Invalid authorization specification" in Form Designer,

    - by Jason Dagit
    I have a form with an OleDbConnection object on it. This form fails to load in the Form Designer with the message: One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes. Invalid authorization specification at ADODB.ConnectionClass.Open(String ConnectionString, String UserID, String Password, Int32 Options) ... (stack trace continues into user code) I've tracked this down to the OleDbConnection string. If I hardcode in the server IP, username/password/dbinstance into the constructor of the GUI form then the form will load in the designer. At run-time it is not an issue because we require the user to provide the login details. The question: Is it possible to use the OleDbConnection and the Form designer without supplying the database credentials in the source code of the form? For example, is there a property of the OleDbConnection or Form that I can set so that it doesn't need to access the database during Form design? My concern is that if we ever move the database server or change the login that the code will stop working in the designer.

  • Trace PRISM / CAL events (best practice?)

    - by Christian
    Ok, this question is for people with either a deep knowledge of PRISM or some magic skills I just lack (yet). The Background is simple: Prism allows the declaration of events to which the user can subscribe or publish. In code this looks like this: _eventAggregator.GetEvent<LayoutChangedEvent>().Subscribe(UpdateUi, true); _eventAggregator.GetEvent<LayoutChangedEvent>().Publish("Some argument"); Now this is nice, especially because these events are strongly typed, and the declaration is a piece of cake: public class LayoutChangedEvent : CompositePresentationEvent<string> { } But now comes the hard part: I want to trace events in some way. I had the idea to subscribe using a lambda expression calling a simple log message. Worked perfectly in WPF, but in Silverlight there is some method access error (took me some time to figure out the reason).. If you want to see for yourself, try this in Silverlight: eA.GetEvent<VideoStartedEvent>().Subscribe(obj => TraceEvent(obj, "vSe", log)); If this would be possible, I would be happy, because I could easily trace all events using a single line to subscribe. But it does not... The alternative approach is writing a different functions for each event, and assign this function to the events. Why different functions? Well, I need to know WHICH event was published. If I use the same function for two different events I only get the payload as argument. I have now way to figure out which event caused the tracing message. I tried: using Reflection to get the causing event (not working) using a constructor in the event to enable each event to trace itself (not allowed) Any other ideas? Chris PS: Writing this text took me most likely longer than writing 20 functions for my 20 events, but I refuse to give up :-) I just had the idea to use postsharp, that would most likely work (although I am not sure, perhaps I end up having only information about the base class).. Tricky and so unimportant topic...

  • How do I add dynamic htmlAttributes to htmlhelper ActionLinks?

    - by camainc
    In my master page I have a top-level menu that is created using ActionLinks: <ul id="topNav"> <li><%=Html.ActionLink("Home", "Index", "Home")%></li> <li><%=Html.ActionLink("News", "Index", "News")%></li> <li><%=Html.ActionLink("Projects", "Index", "Projects")%></li> <li><%=Html.ActionLink("About", "About", "Home")%></li> <li><%=Html.ActionLink("Contact", "Contact", "Home")%></li> <li><%=Html.ActionLink("Photos", "Photos", "Photos")%></li> </ul> I want to dynamically add a class named "current" to the link that the site is currently pointing to. So, for example, when the site is sitting at the home page, the menu link would render like this: <li><a class="current" href="/">Home</a></li> Do I have to overload the ActionLink method to do this, or create an entirely new HtmlHelper, or is there a better way? I'm fairly new to MVC, so I'm not sure what is the correct way to go about this. Thanks in advance.
