    - by nRk
    Hi, I am consuming one webservice, while consuming there can different types expception might occur depeninding on various situation like.. network failur, invalid soap data or exception from serverside also might occur. How can I differntiate between these different excpetion? Because in my application, with these exceptions I need to update the various status Like: if network failure occurs Status will be "unable to connect webservice" so I can try after sometime later. If exception comes from Web server , no need to call/try again. Thanks nRk

  • Parameter becoming zero somewhere

    - by Nick
    Hey guys, Something really weird is happening: when I call foo(100*1.0f), somewhere along the line that becomes 0. To verify I put a breakpoint on foo(), and it indeed is zero and it indeed gets called with 100*1.0f. The code is in Obj-C++. Here is the calling function in XCode's GDB frontend, as you can see, score*scoreMultiplier is 100. And here is the called function in XCode's GDB frontend, here _score is 0.

  • Performance - FunctionCall vs Event vs Action vs Delegate

    - by hwcverwe
    Currently I am using Microsoft Sync Framework to synchronize databases. I need to gather information per record which is inserted/updated/deleted by Microsoft Sync Framework and do something with this information. The sync speed can go over 50.000 records per minute. So that means my additional code need to be very lightweight otherwise it will be a huge performance penalty. Microsoft Sync Framework raises an SyncProgress event for each record. I am subscribed to that code like this: // Assembly1 SyncProvider.SyncProgress += OnSyncProgress; // .... private void OnSyncProgress(object sender, DbSyncProgressEventArgs e) { switch (args.Stage) { case DbSyncStage.ApplyingInserts: // MethodCall/Delegate/Action<>/EventHandler<> => HandleInsertedRecordInformation // Do something with inserted record info break; case DbSyncStage.ApplyingUpdates: // MethodCall/Delegate/Action<>/EventHandler<> => HandleUpdatedRecordInformation // Do something with updated record info break; case DbSyncStage.ApplyingDeletes: // MethodCall/Delegate/Action<>/EventHandler<> => HandleDeletedRecordInformation // Do something with deleted record info break; } } Somewhere else in another assembly I have three methods: // Assembly2 public class SyncInformation { public void HandleInsertedRecordInformation(...) {...} public void HandleUpdatedRecordInformation(...) {...} public void HandleInsertedRecordInformation(...) {...} } Assembly2 has a reference to Assembly1. So Assembly1 does not know anything about the existence of the SyncInformation class which need to handle the gathered information. So I have the following options to trigger this code: use events and subscribe on it in Assembly2 1.1. EventHandler< 1.2. Action< 1.3. Delegates using dependency injection: public class Assembly2.SyncInformation : Assembly1.ISyncInformation Other? I know the performance depends on: OnSyncProgress switch using a method call, delegate, Action< or EventHandler< Implementation of SyncInformation class I currently don't care about the implementation of the SyncInformation class. I am mainly focused on the OnSyncProgress method and how to call the SyncInformation methods. So my questions are: What is the most efficient approach? What is the most in-efficient approach? Is there a better way than using a switch in OnSyncProgress?

  • In jQuery, is there any way to only bind a click once?

    - by Chris Henry
    I have an ajax app that will run functions on every interaction. I'd like to be able to run my setup function each time so all my setup code for that function remains encapsulated. However, binding elements more than once means that the handler will run more than once, which is obviously undesirable. Is there an elegant way in jQuery to call bind on an element more than once without the handler being called more than once?

  • How do i know in the detail view what cell in tableview was selected?

    - by Daniel Rotaru
    how can i know what tableview cell was selected?(being in the detail view) The problem is that. I have an table view controller. Here are parsed from the internet entries to the table. So it's a dynamic tabe view that loads from internet. I will not know how many entries will be in the table so i will not know what details view to call when i click a row. So i have maked one view. This view contains an calendar. On this calendar(wich is the detail iew) i will parse data from internet depending on the selected row. For exemple: i have table: entry 1, entry 2,entry 3,entry 4 When i click entry 2 i need to call a php with the argument entry 2. The php will know what entry on the table i have selected and will generate me the correct xml that i will parse. Here is my tableview didSelectRow function: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic -- create and push a new view controller if(bdvController == nil) bdvController = [[BookDetailViewController alloc] initWithNibName:@"BookDetailView" bundle:[NSBundle mainBundle]]; Villa *aVilla = [appDelegate.villas objectAtIndex:indexPath.row]; [self.navigationController pushViewController:bdvController animated:YES] And here is my self view function on detailviewcontroller: -(void)loadView { [super loadView]; self.title=@"Month" UIBarButtonItem *addButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"ListView" style:UIBarButtonItemStyleDone target:self action:@selector(add:)]; self.navigationItem.rightBarButtonItem = addButtonItem; calendarView = [[[KLCalendarView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 373.0f) delegate:self] autorelease]; appDelegate1 = (XMLAppDelegate *)[[UIApplication sharedApplication] delegate]; myTableView=[[UITableView alloc]initWithFrame:CGRectMake(0, 260, 320, 160)style:UITableViewStylePlain]; myTableView.dataSource=self; myTableView.delegate=self; UIView *myHeaderView=[[UIView alloc]initWithFrame:CGRectMake(0, 0, myTableView.frame.size.width,2)]; myHeaderView.backgroundColor=[UIColor grayColor]; [myTableView setTableHeaderView:myHeaderView]; [self.view addSubview:myTableView]; [self.view addSubview:calendarView]; [self.view bringSubviewToFront:myTableView]; } I think that here in self load i need to make the if procedure.. If indexPath.row=x parse fisier.php?variabila=title_of_rowx but the question is how i know the indexPath variable?

  • When would isSearchable return false for an Oracle JDBC column?

    - by Ian Varley
    In what cases would a call to java.sql.ResultSetMetaData.isSearchable(int col) return false for an Oracle database? The documentation for the method doesn't really answer the question: "Indicates whether the designated column can be used in a where clause." I can think of only one case - when the column is the result of an aggregate function (in which case it would have to be part of a HAVING filter, not a WHERE filter). Are there any other cases?

  • How to present a plot and then return to cmd prompt

    - by ldigas
    I have a data file, and a gnu file, in which my plotting commands are. How can I produce a plot in gnuplot, in a way that I call gnuplot giving it a name of the gnu file ... it gives me the window with a plot ... and after I close it, it returns me not to gnuplot command prompt, but to cmd (windows cmd.exe) command prompt ?

  • How to break out of a loop depending on a CheckBox Checked value while the loop is running?

    - by Rayner Vaz
    Lets say I want to call a function repeatedly if the user selects a CheckBox named "repeat" but the calls to the function should stop as soon as the user 'unchecks' the CheckBox. I tried using the 'Checked', 'Click' and 'Tap' event of the CheckBox but once the loop starts, it does not sense any changes in the checkbox's state. I even tried using a loop inside another button's _Click method, but then that creates a lock on the Button's 'pressed' state. Any ideas/alternate suggestions?

  • Android runs OpenGL ES 1.1 or 1.0?

    - by cjserio
    I'm developing a native app for Android and I'm trying to use functions such as glIsEnabled which appear to be only available in OpenGL ES 1.1. Google's docs claim that NDK 1.6R1 supports OpenGL ES v1.1 but the function call fails with "unimplemented Open GL ES API" and if i do a glGetString(GL_VERSION) it returns "OpenGL ES 1.0 CM" as the version. So if 1.1 is available, what do I have to link against to get it or what else do i need to change to get it?

  • Can an ActiveRecord before_save filter halt the save without halting the transaction?

    - by Michael Boutros
    Is there any way for a before_save filter to halt the entire save without halting the transaction? What I'm trying to do is have a "sample" version of my model that the user can interact with and save but the changes themselves are never actually saved. The following will halt the transaction and (naturally) return false when I call @model.update_attributes: before_filter :ignore_changes_if_sample def ignore_changes_if_sample if self.sample? return false end end Thanks!

  • c++/boost: use tuple ctors when subclassing

    - by bbb
    Hi there, is there some way to use a boost tuple's ctors as an addition to the subclass methods (and ctors) like here? // typedef boost::tuple<int, SomeId, SomeStatus> Conn; // Conn(1); // works and initializes using default ctors of Some* struct Conn : boost::tuple<int, AsynchId, AccDevRetStatus> {}; Conn(1); // "no matching function call" (but i want it so much) T.H.X.

  • Sound Complete Not Firing (AS3)

    - by JasonMc92
    I have a bit of a quandary. I need to call a function inside a MovieClip once a particular sound has finished playing. The sound is played via a sound channel in an external class which I have imported. Playback is working perfectly. Here is the relevent code from my external class, Sonus. public var SFXPRChannel:SoundChannel = new SoundChannel; var SFXPRfishbeg:Sound = new sfxpr_fishbeg(); var SFXPRfishmid:Sound = new sfxpr_fishmid(); var SFXPRfishend3:Sound = new sfxpr_fishend3(); var SFXPRfishend4:Sound = new sfxpr_fishend4() public function PlayPrompt(promptname:String):void { var sound:String = "SFXPR" + promptname; SFXPRChannel = this[sound].play(); } This is called via an import in the document class "osr", thus I access it in my project via "osr.Sonus.---" In my project, I have the following line of code. osr.Sonus.SFXPRChannel.addEventListener(Event.SOUND_COMPLETE, promptIsFinished); function prompt():void { var level = osr.Gradua.Fetch("fish", "arr_con_level"); Wait(true); switch(level) { case 1: osr.Sonus.PlayPrompt("fishbeg"); break; case 2: osr.Sonus.PlayPrompt("fishmid"); break; case 3: osr.Sonus.PlayPrompt("fishend3"); break; case 4: osr.Sonus.PlayPrompt("fishend4"); break; } } function Wait(yesno):void { gui.Wait(yesno); } function promptIsFinished(evt:Event):void { Wait(false); } osr.Sonus.PlayPrompt(...) and gui.Wait(...) both work perfectly, as I use them in other contexts in this part of the project without error. Basically, after the sound finishes playing, I need Wait(false); to be called, but the event listener does not appear to be "hearing" the SOUND_COMPLETE event. Did I make a mistake somewhere? For the record, due to my project structure, I cannot call the appropriate Wait(...) function from within Sonus. Help?
