• redoing object model construction to fit with asynchronous data fetching

  - by Andrew Patterson

  I have a modeled a set of objects that correspond with some real world concepts. TradeDrug, GenericDrug, TradePackage, DrugForm Underlying the simple object model I am trying to provide is a complex medical terminology that uses numeric codes to represent relationships and concepts, all accessible via a REST service - I am trying to hide away some of that complexity with an object wrapper. To give a concrete example I can call TradeDrug d = Searcher.FindTradeDrug("Zoloft") or TradeDrug d = new TradeDrug(34) where 34 might be the code for Zoloft. This will consult a remote server to find out some details about Zoloft. I might then call GenericDrug generic = d.EquivalentGeneric() System.Out.WriteLine(generic.ActiveIngredient().Name) in order to get back the generic drug sertraline as an object (again via a background REST call to the remote server that has all these drug details), and then perhaps find its ingredient. This model works fine and is being used in some applications that involve data processing. Recently however I wanted to do a silverlight application that used and displayed these objects. The silverlight environment only allows asynchronous REST/web service calls. I have no problems with how to make the asychhronous calls - but I am having trouble with what the design should be for my object construction. Currently the constructors for my objects do some REST calls sychronously. public TradeDrug(int code) { form = restclient.FetchForm(code) name = restclient.FetchName(code) etc.. } If I have to use async 'events' or 'actions' in order to use the Silverlight web client (I know silverlight can be forced to be a synchronous client but I am interested in asychronous approaches), does anyone have an guidance or best practice for how to structure my objects. I can pass in an action callback to the constructor public TradeDrug(int code, Action<TradeDrug> constructCompleted) { } but this then allows the user to have a TradeDrug object instance before what I want to construct is actually finished. It also doesn't support an 'event' async pattern because the object doesn't exist to add the event to until it is constructed. Extending that approach might be a factory object that itself has an asynchronous interface to objects factory.GetTradeDrugAsync(code, completedaction) or with a GetTradeDrugCompleted event? Does anyone have any recommendations?

• How to handle both the KeyDown and KeyUp events in a Silverlight 3 TextBox

  - by sako73

  I am attaching handlers to the KeyDown and KeyUp events of a Silverlight 3 TextBox as so: _masterTextBox.KeyDown += (s, args) => { CheckForUserEnteredText(MasterTextBox.Text); args.Handled = false; }; _masterTextBox.KeyUp += (s, args) => { UpdateText(MasterTextBox.Text); }; When I comment out the KeyDown handler, then the KeyUp will trap the event, otherwise, only the KeyDown handler is triggered. Can someone explain why the KeyUp event handler is not firing after the KeyDown handler does? Thanks.

• touchesBegan / Ended incorrectly identifying second, third, etc. touch

  - by Rob

  I have an issue where touchesBegan and touchesEnded are incorrectly identifying my second, third, etc touch if I continue to hold down my first touch. If I lift my finger up off the first touch, then it will recognize the next touch just fine. It's only when I hold my first touch down continuously and then try and touch a different area with a different finger at the same time. It will then incorrectly register that second touch as being from the first touch again. Any insights into how I can fix this? - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch* touch = [touches anyObject]; NSString* filename = [listOfStuff objectAtIndex:[touch view].tag]; // do something with the filename now } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { ITouch* touch = [touches anyObject]; NSString* buttonPressed = [listOfStuff objectAtIndex:[touch view].tag]; // do something with this info now }

• JQuery UI sortable: restore position based on some condition

  - by dafi

  I call sortable.stop() to make an ajax call to store some data after drag&drop operation. When the ajax call returns an error (application logic error or net problem) I want to move the dragged element to its original/start position, how can I achieve it? The scenario should be user drags A to B the sortable.stop() event is called, it triggers an ajax call the ajax call returns an error inside the stop() event we get the ajax error move A to its original position user again move A to B everything is ok A remains in its new position in B Steps 6-8 are shown to clarify a successive drag can be done and previous error must be forgotten

• Calling activateWindow on QDialog sends window to background

  - by Stan

  I am debugging certain application written with C++/Qt4. On Linux it has problems that with certain window managers (gnome-wm/metacity), the main window (based on QDialog) is created in the background (it's not raised). I managed to re-create the scenario using PyQt4 and following code: from PyQt4.QtCore import * from PyQt4.QtGui import * import sys class PinDialog(QDialog): def showEvent(self, event): QDialog.showEvent(self, event) self.raise_() self.activateWindow() if __name__ == "__main__": app = QApplication(sys.argv) widget = PinDialog() app.setActiveWindow(widget) widget.exec_() sys.exit(0) If I remove self.activateWindow() the application works as expected. This seems wrong, since documentation for activateWindow does not specify any conditions under which something like this could happen. My question is: Is there any reason to have activateWindow in showEvent in the first place? If there is some reason, what would be good workaround for focusing issues?

• Rails timezone differences between Time and DateTime

  - by kjs3

  I have the timezone set. config.time_zone = 'Mountain Time (US & Canada)' Creating a Christmas event from the console... c = Event.new(:title = "Christmas") using Time: c.start = Time.new(2012,12,25) = 2012-12-25 00:00:00 -0700 #has correct offset c.end = Time.new(2012,12,25).end_of_day = 2012-12-25 23:59:59 -0700 #same deal using DateTime: c.start = DateTime.new(2012,12,25) = Tue, 25 Dec 2012 00:00:00 +0000 # no offset c.end = DateTime.new(2012,12,25).end_of_day = Tue, 25 Dec 2012 23:59:59 +0000 # same I've carelessly been using DateTime thinking that input was assumed to be in the config.time_zone but there's no conversion when this gets saved to the db. It's stored just the same as the return values (formatted for the db). Using Time is really no big deal but do I need to manually offset anytime I'm using DateTime and want it to be in the correct zone?

• How do you tell what object is being touched in touchesBegan?

  - by Flafla2

  I know that this is a very commonly asked question, but all of the answers on every website don't work! If you still don't know what I mean, then maybe this line of code will help you understand. - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint location = [touch locationInView:self.view]; if (touch.view == nextbutton) [self performSelector:@selector(next)]; if (touch.view == prevbutton) [self performSelector:@selector(previous)]; if (touch.view == moreoptionsbutton) [self performSelector:@selector(moresettings)]; } It doesn't do anything when you touch nextbutton, prevbutton, and more optionsbutton, which are UIImageViews by the way. I have also tried using isEqual: instead of ==, but that hasn't worked out either. Any suggestions?

• bash tips needed for understanding how to escape characters in command-line

  - by Jesper Rønn-Jensen

  My knowledge of commandline bash is missing on a particular area: I constantly forget how to properly escape characters. Today I wanted to echo this string into a file: #!/bin/env bash python -m SimpleHTTPServer echo "#!/bin/env bash\npython -m SimpleHTTPServer" server.sh && chmod +x server.sh -bash: !/bin/env: event not found That's right: Remember to escape ! or bash will think it's a special bash event command. But I can't get the escaping right! \! yields \! in the echoed string, and so does \\!. Furthermore, \n will not translate to a line break. Do you have some general tips that makes it easier for me to understand escaping rules? To be very precise, I'll accept an answer which tells me which characters I should escape on the bash command line? Including how to correctly output newline and exclamation mark in my example.

• Turn off LogEnabled Filter at run time - Logging Enterprise Application Block

  - by Or A

  Hi, so the story go like this: i'm using the Logging Enterprise Application block that provided by microsoft to log events in our application. The goal is to enabled event viewer logging at loading and then turn it off. What i did is to add EventLog TraceListener which write all our logs into the event viewer. What i'm trying to do is to disable it after the application was done loading. The only way that i can thing about is to add a LogEnabled Filter and then turn it off. However, i don't know how to access this filter at run time and disable log on this listener. if you have an idea, please share. Thanks

• Calling AS3 function from html link - Javascript? php? swfaddress?

  - by wdense51

  I have an actionscript function that loads an external swf and is currently linked to a button in the same swf... function btnClick(event:MouseEvent):void{ SoundMixer.stopAll(); removeChild(loader); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onSWFLoaded); loader.load(movieSWF) loader.x=Xpos loader.y=Ypos addChild(loader) } button.addEventListener(MouseEvent.CLICK,btnClick); I'm wondering if there is a way to call this function from a link on the page that the swf is housed on. I'm guessing javascript, php or swfaddress would be the most likely way, but I'm unbelievably new to all this so I'm not sure where to start or how to go about it. Any help would be appreciated.

• Inter Widget Communication for iGoogle like portals

  - by bakore

  I was looking for a platform where widgets developed using various technologies like Java can communicate with each other. In other words When I add widgets to an interface I need them to talk to each other. For example A Click event in one widget should trigger an event in some other widget. I have been looking into the web for solutions and ways to do it, but couldnt find anything concrete. Any pointers or information on this would be great. Something like this http://blogs.sun.com/pdblog/entry/inter_widget_communication_in_cross Google also had a gadget to gadget communication API which was deprecated last year.

• Trouble cross-referencing two XML child nodes in AS3

  - by Dwayne

  I am building a mini language translator out of XML nodes and Actionscript 3. I have my XML ready. It contains a series of nodes with two children in them. Here is a sample: <translations> <entry> <english>man</english> <cockney>geeza</cockney> </entry> <entry> <english>woman</english> <cockney>lily</cockney> </entry> </translations> The AS3 part consist of one input box named "textfield_txt" where the English word will be typed in. An output text field for the translation called "cockney_txt". Finally, one button to execute the translation called "generate_mc". The idea is to have actionscript look through the XML for key English words after the user types it in the "textfield", cross-freferences the children then returns the Cockney translation as a value. The trouble is, when I test it I get no response or error messages- it's completely silent. I'm not sure what I'm doing wrong. At present, I have setup a conditional statement to tell me whether the function works or not. The result is, no it's not! Here's the code below. I hope someone can help. Cheers! generate_mc.buttonMode=true; var English:String; var myXML:XML; var myLoader:URLLoader = new URLLoader(); myLoader.load(new URLRequest("Language.xml")); myLoader.addEventListener(Event.COMPLETE, processXML); function processXML(e:Event):void { myXML = new XML(e.target.data); } generate_mc.addEventListener(MouseEvent.CLICK, onClick); function onClick(event:MouseEvent) { English = textfield.text; cockney_txt.text = myXML.translations.entry.cockney; if(textfield.text.toLowerCase() == myXML.translations.entry.english.toLowerCase){ //return myXML.translations.entry.cockney; trace("success"); }else{ trace("try again!"); // ***I get this as a result } }

• How to time-delay email deliveries?

  - by Michael D

  I'm currently learning about the Drupal email functions, such as drupal_mail and hook_mail, and hook_mail_alter, and I have a problem before me where I'll need to be able to queue emails for delayed delivery. For example, an event signup notification that needs to wait for an hour after the event was registered by a user. And that email has user specific data, so can't be just a generic template email... I'm using the MailQ module, mainly for it's logging capabilities, but I wonder if it (or something else) could be modified to add a configurable delay function? Any ideas?

• Multiple .obj Models in THREE.js and detecting clicked objects

  - by ZedBee

  I have been following along this example to load .obj Model using three.js. Since I needed more than one model to load so I tried this loader.addEventListener( 'load', function ( event ) { var object = event.content; object.position.y = - 80; scene.add( object ); }); loader.load( 'obj/model1.obj' ); loader.load( 'obj/model2.obj' ); First: I don't know whether this is the right approach or not since I searched but didn't find any tutorial loading more than one .obj models. Second: I want to be able to click different models on the screen. I tried this which doest not seem to work for me. Any suggestions on this?

• Setting a session variable in Global.asax causes AJAX errors

  - by Fly_Trap

  I'm getting a very peculiar problem with my asp.net application, it took me an age to track down but I still don't know what is causing this behaviour. If I set a session variable in the Application_PreRequestHandlerExecute event, then my external JavaScript files are ignored, and therfore causing a raft of errors. I have simplified the problem below. E.g. I have file called JScript.js containing the code: function myAlert() { alert("Hi World"); } And in my Default.aspx file I reference the js with the code: <script src="JScript.js" type="text/javascript"></script> And in the body onload event I call the myAlert() function: <body onload="myAlert()"> And finally in the Global.asax file: Private Sub Application_PreRequestHandlerExecute(ByVal sender As Object, ByVal e As EventArgs) HttpContext.Current.Session("myVar") = "MyValue" End Sub If you run the Default.aspx file you will see the js function isnt called, however, if you comment out the line of code Global.asax then the external js is called and the function executed when the page loads. Why is this?

• JQuery - Ajax saving sortables in connected lists when sortable item is moved

  - by Ben Sinclair

  I have multiple JQuery sortable lists that connect with each other... They allow you to assign users to certain roles. Basically what I want to do is when a user is dragged from one list to another, I want JQuery to pick up the first list that the user was moved from so that I can send an AJAX request to delete it from that list in my database. I tried the following but every time you move the user over a list and haven't even dropped it within a list, it sends this request which means I'll be sending multiple AJAX requests... Does that make sense? $( ".selector" ).sortable({ out: function(event, ui) { ... } }); From my testing, I can use the following code to just update the list that user has been moved to so I've got the second half covered: $( ".selector" ).sortable({ receive: function(event, ui) { ... } }); Hopefully I am making sense :)

• Is it possible to get an NSView to pass rightMouseDown: to the next responder without subclassing?

  - by Benedict Cohen

  I have a view which contains a few subviews: mainView subViewA subViewB SubViewC mainView is an NSView constructed from a nib and is controlled with an NSViewController subclass. The subviews are standard views such as NSTextField and NSImageView and are configured to be non-editable. I want mainView to receive rightMouseDown: even when the event is triggered in one of the subviews. The default implementation of rightMouseDown: in NSResponder passes the event to the next responder, but NSView changes the default behaviour and does not pass it to the next responder. I could subclass all of the subviews but this doesn't seem like a very elegant or maintainable solution. How can I get the subviews to pass rightMouseDown: messages to the next responder without subclassing all of the subviews?

• Why are events and commands in MVVM so unsupported by WPF / Visual Studio?

  - by Edward Tanguay

  When creating an WPF application with the MVVM pattern, it seems I have to gather the necessary tools myself to even begin the most rudimentary event handling, e.g. AttachedBehaviors I get from here DelegateCommands I get from here Now I'm looking for some way to handle the ItemSelected event in a ComboBox and am getting suggestions of tricks and workarounds to do this (using a XAML trigger or have other elements bound to the selected item, etc.). Ok, I can go down this road, but it seems to be reinventing the wheel. It would be nice to just have an ItemSelected command that I can handle in my ViewModel. Am I missing some set of standard tools or is everyone doing MVVM with WPF basically building and putting together their own collection of tools just so they can do the simplest plumbing tasks with events and commands, things that take only a couple lines in code-behind with a Click="eventHandler"?

• Boiler plate code replacement - is there anything bad about this code?

  - by Benjol

  I've recently created these two (unrelated) methods to replace lots of boiler-plate code in my winforms application. As far as I can tell, they work ok, but I need some reassurance/advice on whether there are some problems I might be missing. (from memory) static class SafeInvoker { //Utility to avoid boiler-plate InvokeRequired code //Usage: SafeInvoker.Invoke(myCtrl, () => myCtrl.Enabled = false); public static void Invoke(Control ctrl, Action cmd) { if (ctrl.InvokeRequired) ctrl.BeginInvoke(new MethodInvoker(cmd)); else cmd(); } //Replaces OnMyEventRaised boiler-plate code //Usage: SafeInvoker.RaiseEvent(this, MyEventRaised) public static void RaiseEvent(object sender, EventHandler evnt) { var handler = evnt; if (handler != null) handler(sender, EventArgs.Empty); } } EDIT: See related question here UPDATE Following on from deadlock problems (related in this question), I have switched from Invoke to BeginInvoke (see an explanation here). Another Update Regarding the second snippet, I am increasingly inclined to use the 'empty delegate' pattern, which fixes this problem 'at source' by declaring the event directly with an empty handler, like so: event EventHandler MyEventRaised = delegate {};
