  • Space a valid delimiter for email addresses in email header?

    - by semanticalo
    Is it syntactically correct to delimit multiple email recipients in the "To" header of an email with spaces only or do I need to use another delimiter (a semicolon or the like)? Example (MIME data reads as follows): Date: Mon, 04 Oct 2010 06:14:16 +0200 From: [email protected] To: [email protected] [email protected] [email protected] Subject: Test Subject The above will be processed by many email processing applications, but I need to know whether it's correct according to standard (RFC). Unfortunately I didn't find anything useful on the internet so far. Thanks a million for your help!

  • Decode amf3 object using PHP

    - by Xuki
    My flash code: var request=new URLRequest('http://localhost/test.php'); request.method = URLRequestMethod.POST; var data = new URLVariables(); var bytes:ByteArray = new ByteArray(); bytes.objectEncoding = ObjectEncoding.AMF3; //write an object into the bytearray bytes.writeObject( { myString:"Hello World"} ); data.data = bytes; request.data = data; var urlLoader:URLLoader = new URLLoader(); urlLoader.dataFormat = URLLoaderDataFormat.BINARY; urlLoader.addEventListener(Event.COMPLETE, onCompleteHandler); urlLoader.load(request); function onCompleteHandler(evt:Event):void { trace(evt.target.data); } PHP code: define("AMF_AMF3",1); $data = $_POST['data']; echo amf_decode($data, AMF_AMF3); Basically I need to send an AMF3 object from Flash to PHP and unserialize it. I'm using AMFEXT extension but couldn't get it to work. Any idea?

  • Need Advice on designing ATL inproc Server (dll) that serves as both a soure and a sink of events.

    - by Andrew
    Hi, I need to design an ATL inproc server that besides exposing methods and properties, also can fire events (source) and serve as a sink for a third party COM control that fires events. I would assume that this is a fairly common requirement. I can also foresee several "gotchas" that I would like to read up on before commencing the design. My questions/concerns are: Can someone point me to an example? Which threading model to use? Should I have a seperate COM object for the sink? Should I, and how do I, protect certain memory. For example, my server will receive data from the third party control. It will save this, and in some cases, fire an event to interested clients. The interested clients will request the data through a standard method or property. I did try to research this myself. I can find many examples of COM servers that are soures, and some that are sinks, but never both. The only post I did find was this: http://www.generation-nt.com/us/atl-control-an-event-source-sink-help-9098542.html Which strongly advocates putting the sink on a seperate COM object. Any leads, tutorials or ideas would be much appreciated. Thanks, Andrew

  • YUI button onclick get value

    - by Simon
    I have a a set of yui buttons generated using the standard yui html. <span class="yui-button yui-checkbox-button" id="analystbutton1"> <span class="first-child"> <button type="button" class="facetbutton" tabindex="0" id="analystbutton1-button"> Joe Bloggs </button> </span> </span> I create the buttons like so, and I then have some javascript to create the button and the listener. var analystCButton1 = new YAHOO.widget.Button("analystbutton1", { type:"checkbox", value:"BLOGGS", checked:false }); analystCButton1.on("click", onFacetClick); Finally I have the onFacetClick function var onFacetClick = function (e) { // e is the event var target = YAHOO.util.Event.getTarget(e); var button = new YAHOO.widget.Button(target); alert(button.get('type')); alert(button.get('id')); alert(button.get('value')); }; When I click on any of my buttons the first two alerts display the type and id (although not what I would expect). I cannot get the value, the alert doesn't fire, but I see no error in FireBug or the error console. alert(button.get('type')); returns push - I would expect checkbox alert(button.get('id')); returns analystbutton1-button

  • Setting up 802.1X wireless connection on OSX

    - by hizki
    I am an OSX user, I have Snow Leopard 10.6.5 and an updated AirPort. I am trying to connect to my university's wireless network, but it has a complex security that I am having trouble defining... Here there are instructions for connecting with Windows XP, Windows 7 and Linux. Can someone please instruct me what should I do to set up this network on my MAC? Thank you. P.S. I have had previous success in setting up this network, but I have no idea what I did that made it work. Since I updated my AirPort it worked only seldomly and very slowly... Before the update, even when it worked it never remembered my password.

  • reading Twitter API with JSON framework

    - by iPixFolio
    Hi, I'm building a twitter reader into an app. I'm using this JSON library to parse the twitter API. I'm seeing some odd results on certain messages. I know that the Twitter API returns results in UTF8 format. I'm wondering if I'm doing something wrong when reading the JSON parsed fields. My code is spread out across multiple classes so it's hard to give a concise code drop with the symptoms, but here's what I've got: I am using ASIHTTP for async HTTP processing. Here is processing a response from ASIHTTP: ... NSMutableString* tempString = [[NSMutableString alloc] initWithString:[request responseString]]; NSError *error; SBJSON *json = [[SBJSON alloc] init]; id JSONresponse = [json objectWithString:tempString error:&error]; [tempString release]; [json release]; if (JSONresponse) { self.response = JSONresponse; ... self.response holds the JSON representation of the result from the Twitter call. Now, I will take the JSON response and write each tweet into a container object (Tweet). in the following code, the response from above is referenced as request.response: ... // save list of albums to local cache for (NSDictionary* response in request.response) { Tweet* tweet = [[Tweet alloc] init]; tweet.text = [response objectForKey:@"text"]; tweet.id = [response objectForKey:@"id"]; tweet.created = [response objectForKey:@"created_at"]; [Tweet addTweet:tweet]; [tweet release]; } ... at this point, I have a container holding the tweets. I'm only keeping 3 fields from the tweet: "id", "text", and "created_at". the "text" field is the problem field. To display the tweets, I build an HTML page from the container of tweets, like this: ... Tweet* tweet = nil; for (int i = 0; i < [Tweet tweetCount]; i++) { tweet = [Tweet tweetAtIndex:i]; [html appendString:@"<div class='tweet'>"]; [html appendFormat:@"<div class='tweet-date'>%@</div>", tweet.created ]; [html appendFormat:@"<div class='tweet-text'>%@</div>", tweet.text ]; [html appendString:@"</div>"]; } ... In another routine, I save the HTML page to a temp file. if (html && [html length] > 0 ) { NSString* uniqueString = [[NSProcessInfo processInfo] globallyUniqueString]; NSString* filename = [NSString stringWithFormat:@"%@.html", uniqueString ]; filename = [tempDir stringByAppendingPathComponent:filename]; NSError* error = nil; [html writeToFile:filename atomically:NO encoding:NSUTF8StringEncoding error:&error]; ... I then create a URLRequest from the file and load it into an UIWebview: NSURL* url = [NSURL fileURLWithPath:filename]; NSURLRequest* request = [NSURLRequest requestWithURL:url]; [self.webView loadRequest:request]; ... At this point, I can see the tweets in a browser window. some of the tweets will show invalid characters like this: iPhone 4 ad spoofed with Glee’s Jane Lynch ... Glee’s should be Glee's Can anybody shed any light on what I'm doing wrong and offer suggestions on how to fix? basically, to summarize: I'm reading a UTF8 feed with JSON I write the UTF8 strings into an HTML file I display the HTML file with UIWebview. some of the UTF8 strings are not properly decoded. I need to know where to decode them and how to do it. thanks! Mark

  • Objects in JavaScript defined and undefined at the same time (in a FireFox extension)

    - by Alexey Romanov
    I am chasing down a bug in a FireFox extension. I've finally managed to see it for myself (I've only had reports before) and I can't understand how what I saw is possible. One error message from my extension in the Error Console is "gBrowser is not defined". This by itself would be surprising enough, since the overlay is over browser.xul and navigator.xul, and I expect gBrowser to be available from both. Even worse is the actual place where it happens: line 101 of nextplease.js. That is, inside the function isTopLevelDocument, which is only called from onContentLoaded, which is only called from onLoad here: gBrowser.addEventListener(this.loadType, function (event) { nextplease.loadListener.onContentLoaded(event); }, true); So gBrowser is defined in onLoad, but somehow undefined in isTopLevelDocument. When I tried to actually use the extension, I got another error: "nextplease is not defined". The interesting thing is that it happened on lines 853 and 857. That is, inside the functions nextplease.getNextLink = function () { nextplease.getLink(window.content, nextplease.NextPhrasesMap, nextplease.NextImagesMap, nextplease.isNextRegExp, nextplease.NEXT_SEARCH_TYPE); } nextplease.getPrevLink = function () { nextplease.getLink(window.content, nextplease.PrevPhrasesMap, nextplease.PrevImagesMap, nextplease.isPrevRegExp, nextplease.PREV_SEARCH_TYPE); } So nextplease is somehow defined enough to call these functions, but isn't defined inside them. Finally, executing typeof(nextplease) in Execute JS returns "object". Same for gBrowser. How can this happen? Any ideas?

  • Dojo Widgets not rendering when returned in response to XhrPost

    - by lazynerd
    I am trying to capture the selected item in a Dijit Tree widget to render remaining part of the web page. Here is the code that captures the selected item and sends it to Django backend: <div dojoType="dijit.Tree" id="leftTree" store="leftTreeStore" childrenAttr="folders" query="{type:'folder'}" label="Explorer"> <script type="dojo/method" event="onClick" args="item"> alert("Execute of node " + termStore.getLabel(item)); var xhrArgs = { url: "/load-the-center-part-of-page", handleAs: "text", postData: dojo.toJson(leftTreeStore.getLabel(item), true), load: function(data) { dojo.byId("centerPane").innerHTML = data; //window.location = data; }, error: function(error) { dojo.byId("centerPane").innerHTML = "<p>Error in loading...</p>"; } } dojo.byId("centerPane").innerHTML = "<p>Loading...</p>"; var deferred = dojo.xhrPost(xhrArgs); </script> </div> The remaining part of the page contains HTML code with dojo widgets. This is the code sent back as 'response' to the select item event. Here is a snippet: <div dojoType="dijit.layout.TabContainer" id="tabs" jsId="tabs"> <div dojoType="dijit.layout.BorderContainer" title="Dashboard"> <div dojoType="dijit.layout.ContentPane" region="bottom"> first tab </div> </div> <div dojoType="dijit.layout.BorderContainer" title="Compare"> <div dojoType="dijit.layout.ContentPane" region="bottom"> Second Tab </div> </div> </div> It renders this html 'response' but without the dojo widgets. Is handleAs: "text" in XhrPost the culprit here?

  • Actionscript image download open custom viewer

    - by Vish
    Hi Gurus, i am downloading tiff images from WAMP server using our Flex AIR client. Using the following code for that. public static function requestDownload(id:int, defaultName:String):void { //POST params var urlVars:URLVariables = new URLVariables(); urlVars.action = "download"; urlVars.fid = id; var urlReq:URLRequest = new URLRequest(); urlReq.url = Config.getServerURL(); urlReq.data = urlVars; Config.fileReference.addEventListener(Event.,FileDownload.requestDownloadResultV); try { Config.fileReference.download(urlReq, defaultName); } catch (e:Error) { Alert.show("Error in downloading the file"); } } public static function requestDownloadResultV(e:Event):void { Alert.show("File downloaded"); } No issues with the download. It automatically prompts for a Save dialog. Works well. But i want to open the image being downloaded in a viewer(flash viewer or any) instead of the save dialog. Please help me. Thanks Vish.

  • Writing a code example

    - by Stefano Borini
    I would like to have your feedback regarding code examples. One of the most frustrating experiences I sometimes have when learning a new technology is finding useless examples. I think an example as the most precious thing that comes with a new library, language, or technology. It must be a starting point, a wise and unadulterated explanation on how to achieve a given result. A perfect example must have the following characteristics: Self contained: it should be small enough to be compiled or executed as a single program, without dependencies or complex makefiles. An example is also a strong functional test if you correctly installed the new technology. The more issues could arise, the more likely is that something goes wrong, and the more difficult is to debug and solve the situation. Pertinent: it should demonstrate one, and only one, specific feature of your software/library, involving the minimal additional behavior from external libraries. Helpful: the code should bring you forward, step by step, using comments or self-documenting code. Extensible: the example code should be a small “framework” or blueprint for additional tinkering. A learner can start by adding features to this blueprint. Recyclable: it should be possible to extract parts of the example to use in your own code Easy: An example code is not the place to show your code-fu skillz. Keep it easy. helpful acronym: SPHERE. Prototypical examples of violations of those rules are the following: Violation of self-containedness: an example spanning multiple files without any real need for it. If your example is a python program, keep everything into a single module file. Don’t sub-modularize it. In Java, try to keep everything into a single class, unless you really must partition some entity into a meaningful object you need to pass around (and java mandates one class per file, if I remember correctly). Violation of Pertinency: When showing how many different shapes you can draw, adding radio buttons and complex controls with all the possible choices for point shapes is a bad idea. You de-focalize your example code, introducing code for event handling, controls initialization etc., and this is not part the feature you want to demonstrate, they are unnecessary noise in the understanding of the crucial mechanisms providing the feature. Violation of Helpfulness: code containing dubious naming, wrong comments, hacks, and functions longer than one page of code. Violation of Extensibility: badly factored code that have everything into a single function, with potentially swappable entities embedded within the code. Example: if an example reads data from a file and displays it, create a method getData() returning a useful entity, instead of opening the file raw and plotting the stuff. This way, if the user of the library needs to read data from a HTTP server instead, he just has to modify the getData() module and use the example almost as-is. Another violation of Extensibility comes if the example code is not under a fully liberal (e.g. MIT or BSD) license. Violation of Recyclability: when the code layout is so intermingled that is difficult to easily copy and paste parts of it and recycle them into another program. Again, licensing is also a factor. Violation of Easiness: Yes, you are a functional-programming nerd and want to show how cool you are by doing everything on a single line of map, filter and so on, but that could not be helpful to someone else, who is already under pressure to understand your library, and now has to understand your code as well. And in general, the final rule: if it takes more than 10 minutes to do the following: compile the code, run it, read the source, and understand it fully, it means that the example is not a good one. Please let me know your opinion, either positive or negative, or experience on this regard.

  • jQuery: How can I animate to a taller height with the height being added to the top of the element?

    - by Jannis
    Hi, I have a simple problem but I am not sure how to solve it. Basically I have some hidden content that, once expanded, requires a height of 99px. While collapsed the element holding it section#newsletter is set to be 65px in height. LIVE EXAMPLE: http://dev.supply.net.nz/asap-finance-static/ On the click of a#signup_form the section#newsletter is expanded to 99px using the following jQuery: $('#newsletter_form').hide(); // hide the initial form fields $('#form_signup').click(function(event) { event.preventDefault(); // stop click // animate $('section#newsletter').animate({height: 99}, 400, function() { $('#newsletter_form').show(300); }) }); All this works great except for the fact that this element sits in a sticky footer so its initial height is used to position it. Animating the height of this element causes scrollbars on the browser, because the 34px added are added to the bottom of the element, so my question: How can I add these 34px to the top of the element so the height expands upwards into the body not downwards? Thanks for reading, I look forward to your help and suggestions. Jannis

  • How do I set default search conditions with Searchlogic?

    - by Danger Angell
    I've got a search form on this page: http://staging-checkpointtracker.aptanacloud.com/events If you select a State from the dropdown you get zero results because you didn't select one or more Event Division (checkboxes). What I want is to default the checkboxes to "checked" when the page first loads...to display Events in all Divisions...but I want changes made by the user to be reflected when they filter. Here's the index method in my Events controller: def index @search = Event.search(params[:search]) respond_to do |format| format.html # index.html.erb format.xml { render :xml => @events } end end Here's my search form: <% form_for @search do |f| %> <div> <%= f.label :state_is, "State" %> <%= f.select :state_is, ['AK','AL','AR','AZ','CA','CO','CT','DC','DE','FL','GA','HI','IA','ID','IL','IN','KS','KY','LA','MA','MD','ME','MI','MN','MO','MS','MT','NC','ND','NE','NH','NJ','NM','NV','NY','OH','OK','OR','PA','RI','SC','SD','TN','TX','UT','VA','VT','WA','WI','WV','WY'], :include_blank => true %> </div> <div> <%= f.check_box :division_like_any, {:name => "search[:division_like_any][]"}, "Sprint", :checked => true %> Sprint (2+ hours)<br/> <%= f.check_box :division_like_any, {:name => "search[:division_like_any][]"}, "Sport" %> Sport (12+ hours)<br/> <%= f.check_box :division_like_any, {:name => "search[:division_like_any][]"}, "Adventure" %> Adventure (18+ hours)<br/> <%= f.check_box :division_like_any, {:name => "search[:division_like_any][]"}, "Expedition" %> Expedition (48+ hours)<br/> </div> <%= f.submit "Find Events" %> <%= link_to 'Clear', '/events' %> <% end %>

  • Drawing to the canvas

    - by Mattl
    I'm writing an android application that draws directly to the canvas on the onDraw event of a View. I'm drawing something that involves drawing each pixel individually, for this I use something like: for (int x = 0; x < xMax; x++) { for (int y = 0; y < yMax; y++){ MyColour = CalculateMyPoint(x, y); canvas.drawPoint(x, y, MyColour); } } The problem here is that this takes a long time to paint as the CalculateMyPoint routine is quite an expensive method. Is there a more efficient way of painting to the canvas, for example should I draw to a bitmap and then paint the whole bitmap to the canvas on the onDraw event? Or maybe evaluate my colours and fill in an array that the onDraw method can use to paint the canvas? Users of my application will be able to change parameters that affect the drawing on the canvas. This is incredibly slow at the moment.

  • Windows Phone - OnNavigatingFrom - problem

    - by Martin Anderson
    I believe this is just a problem for me, due to my lack of programming ability. I am currently exploring transitions between page navigation with Windows Phone apps. I was originally using storyboards, and completed event handlers to have my pages animate on and off screen. These leads to the a problem when you want to navigate to many pages from one page, using the same transition. So I have started looking at OnNavigatedTo, and OnNavigatingFrom events and while it is working nicely for OnNavigatedTo, the later just wont work. It seems the Microsoft.Phone.Navigation assembly does not contain OnNavigatingFrom, and referencing System.Windows.Navigation, compiles ok, but I cant get pages to animate off upon navigation. I have a button on my Page2, which I want to go back to my MainPage (after I over-rided the back key with a message box for testing). I have transitions made on the page, and I have this as the event handler code... private void btnP2_BackToP1Clicked(object sender, System.Windows.RoutedEventArgs e) { NavigationService.Navigate(new Uri("/MainPage.xaml", UriKind.Relative)); } With this code for the OnNavigatedTo and OnNavigatingFrom events... protected override void OnNavigatedTo(PhoneNavigationEventArgs e) { PageTransition_In.Begin(); } // // protected override void OnNavigatingFrom(NavigatingCancelEventArgs e) { PageTransition_Out.Begin(); base.OnNavigatingFrom(e); } I have the feeling that OnNavigatingFrom may not(yet) be supported for Windows Phone Apps. OnNavigatedFrom is part of Microsoft.Phone.Navigation, but it only performs actions once the page is no longer active, which is too late to perform any animation effects.

  • How can I test this SQL Server performance Utility?

    - by Martin Smith
    As part of my MSc I need to do a three month project later this year. I have decided to do something which will likely be useful for me in the workplace and spend the time getting to understand SQL Server internals. The deliverable for this project will be a performance advisor looking at a variety of different rules. Some static such as finding redundant indexes, some more dynamic such as using XEvents to find outlying invocations of stored procedure execution times when certain parameters are passed. I am struggling to come up with a good way of testing this though. I can obviously design a "bad" database and a synthetic workload that my tool will pick up issues on but I also need to demonstrate that it has real world utility. Looking at the self tuning database literature it is common to use TPC benchmarks but I've had a look at the TPCC site and it looks very time consuming to implement and not that good a fit to my project's testing needs in any event (I would still be able to "rig" it by the decisions I made on indexing or physical architecture). Plan A would be to find willing beta tester(s) but in the event that isn't possible I will need a fallback plan. The best idea I have come up with so far is to use the various MS sample applications as examples of real world applications. e.g. http://msftdpprodsamples.codeplex.com/ http://www.asp.net/community/projects/ Does anyone have any better suggestions?

  • W3 Total Cache or WP Super Cache?

    - by javipas
    I'm just preparing the setup of a new VPS where I will migrate a WordPress blog with a good traffic (currently, around 40k pageviews a day), and I was thinking about the caching strategy. I've found different ideas and recommendations, but from previous experiences I will setup a Nginx+PHP-FPM+MySQL (LEMP) system on a Linode VPS. I've read also about setting Nginx as a reverse proxy with Apache, and even using Varnish too, but I don't know if all of this can benefit the speed/performance of the blog (that's the only thing that will be installed on the VPS). The question now is... would you recommend W3 Total Cache or WP Super Cache? I've used W3 on some blogs, but I haven't noticed great benefits and don't need all its options, so I think I could give the veteran WP Super Cache a try. Besides, some users have complained about W3 complex configuration and lack of performance (even consumig more CPU) on some cases.

  • jQuery Autocomplete & jTemplates - handling response

    - by Diegos Grace
    Has anyone had any experience with using jTemplates to display autocomplete results. I have the following $("#address-search").autocomplete({ source: "/Address/SearchAddress", minLength: 2, delay: 400, focus: function (event, ui) { $('#address-search').val(ui.item.name); return false; }, parse: function(data) { $("#autocomplete-results").setTemplate($("#templateHolder").html()); $("#autocomplete-results").processTemplate(data); }, select: function (event, ui) { $('#address-search').val(ui.item.name); $('#search-address-id').val(ui.item.id); $('#search-description').html(ui.item.address); }); and the simple jtemplate holder: <script type="text/html" id="templateHolder"> <ul class="autocomplete"> {#foreach $T as data} <li>{$T.name}</li> {#/for} </ul> </script> Above i'm using 'Parse' to format results, I've also tried the autocomplete result method but not having any luck so far. The only success I've had is by using the private method ._renderItem and formatting the data that way but we want to render the output using the jTemplate. Any advice appreciated.

  • Opengl Iphone SDK: How to tell if you're touching an object on screen?

    First is my touchesBegan function and then the struct that stores the values for my object. I have an array of these objects and I'm trying to figure out when I touch the screen if I'm touching an object on the screen.

  • How to move/drag multiple images with CALayer???

    - by gbf.sara
    I have more than 10 images in screen and i want to move each image using CALayer concept. While am trying to move first image,its working. Even when i drag my second image also, its working. But after that when i get back to first image and when i try to move , am struck up. its not working. I dono where it went wrong. Here's ma code //Assigning Layer to UIImage// layer = [CALayer layer]; UIImage *image1 = [UIImage imageNamed:[NSString stringWithFormat:@"%@_thumb.png",[tiv imageName]]]; layer.contents = (id)image1.CGImage; layer.position=CGPointMake(200,200); layer.frame = CGRectMake(110, 180, 100, 100); [self.view.layer addSublayer:layer]; [layer needsDisplay]; [self.view.layer needsDisplay]; [layer needsLayout]; //Here i try to move my image// - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesMoved:touches withEvent:event]; NSArray *allTouches = [touches allObjects]; int count = [allTouches count]; if (count == 1) { if (CGRectContainsPoint([layer frame], [[allTouches objectAtIndex:0] locationInView:self.view])) { layer.position = [[allTouches objectAtIndex:0] locationInView:self.view]; return; } } if (count > 1) { if (CGRectContainsPoint([layer frame], [[allTouches objectAtIndex:-1] locationInView:self.view])) { layer.position = [[allTouches objectAtIndex:0] locationInView:self.view]; return; } } } Also ive planned to use single CALayer for multiple images.. When i click an image, it should be placed in that CALayer and when i click another, the same CALayer should take the latter one. So tat whenever i drag an image it should move(no matter how many images r there) . Do u think this concept will work out or is there any other idea??? My concept may seems to be a basic one. Am new to this environment n so kindly help me..

  • MS Access form_current() firing multiple times

    - by Eric G
    I have a form with two subforms (on separate tab pages). It's an MDB project in Access 2003. When it initially opens, Form_Current on the active subform fires once, as it should. But when you move to another record (ie. from the main form), it fires Form_Current on the active subform 4 times. Then subsequent record-moves result in Form_Current firing 2 times. This is a pain, because the subforms have a lot of fields that get moved and/or hidden and so it jumps around for every Form_Current, not to mention being slow. I am opening the form with a filter via DoCmd.OpenForm (actually it sends the filter in via OpenArgs). FilterOn is only set once, in Form_Open on the main form, never in the subforms. Form_Current is not called explicitly anywhere else in the code. When I look at the call stack when Form_Current fires moving the first time, it looks like: my_subform.Form_Current [<Debug Window>] my_subform.Form_Current So it seems like something in Form_Current is triggering another Form_Current event. But only on the first record move. The code in Form_Current is somewhat complex, involving custom classes and event callbacks, but generally does not touch the table data. The only thing I can think might be triggering a Form_Current is that it checks OldValue on form controls - could this be causing it? Or anything else come to mind? Thanks. Eric

  • Intent.putExtras not consistent

    - by martinjd
    I have a weird situation with AlarmManager. I am scheduling an event with AlarmManager and passing in a string using intent.putExtra. The string is either silent or vibrate and when the receiver fires the phone should either turn of the ringer or set the phone to vibrate. The log statement correctly outputs the expected value each time. Intent intent; if (eventType.equals("start")) { intent = new Intent(context, SReceiver.class); } else { intent = new Intent(context, EReceiver.class); } intent.setAction(eventType+Long.toString(newId)); Log.v("EditQT",ringerModeType.toUpperCase()); intent.putExtra("ringerModeType", ringerModeType.toUpperCase()); PendingIntent appIntent = PendingIntent.getBroadcast(context, 0, intent, 0); AlarmManager alarmManager = (AlarmManager) getSystemService (Context.ALARM_SERVICE); alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), appIntent); The receiver that fires when the alarm executes also has a log statement and I can see the first time around that the statement outputs the expected string either SILENT or VIBRATE. The alarm executes and then I change the value for putExtra to opposite string and the receiver still displays the previous value event though the call from the code above shows that the new value was passed in. The value for setAction is the same each time. audioManager = (AudioManager) context.getSystemService(Activity.AUDIO_SERVICE); Log.v("Start",intent.getExtras().get("ringerModeType").toString()); if (intent.getExtras().get("ringerModeType").equals("SILENTMODE")) { audioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT); } else { audioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE); } Any thoughts?

  • QT: custom widget in QScrollArea

    - by slimscsi
    I am attempting to create a custom widget. My Widget renders itself unless it is inside a scroll area. The code below works. If I change the if(0) to an if(1) inside the MainWindow constructor, it will not render the "Hello World" string. I assume that I must (re)implement some additional methods, but so far I have not been able to find the correct ones with trial and error. // hellowidget.h #ifndef HELLOWIDGET_H #define HELLOWIDGET_H #include <QtGui> class HelloWidget : public QWidget { Q_OBJECT public: HelloWidget(QWidget *parent = 0); void paintEvent(QPaintEvent *event); }; #endif // HELLOWIDGET_H // hellowidget.cpp #include "hellowidget.h" HelloWidget::HelloWidget(QWidget *parent) : QWidget(parent) { } void HelloWidget::paintEvent(QPaintEvent *event) { QPainter painter(this); painter.drawText(rect(), Qt::AlignCenter, "Hello World"); } // mainwindow.h #ifndef MAINWINDOW_H #define MAINWINDOW_H #include <QtGui> class MainWindow : public QMainWindow { Q_OBJECT public: MainWindow(QWidget *parent = 0); ~MainWindow(); private: }; #endif // MAINWINDOW_H // mainwindow.cpp #include "mainwindow.h" #include "hellowidget.h" MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) { HelloWidget *hello = new HelloWidget; QWidget *central = hello; if( 0 ) { QScrollArea *scroll = new QScrollArea ; scroll->setWidget(hello); central = scroll; } setCentralWidget( central ); } MainWindow::~MainWindow() { } // main.cpp #include <QtGui/QApplication> #include "mainwindow.h" int main(int argc, char *argv[]) { QApplication a(argc, argv); MainWindow w; w.show(); return a.exec(); }
