  • Is it okay to use <input type="tel"/> now?

    - by Michael
    I'm working on a mobile phone web app and I have several text fields that could benefit from iPhone's will adjust the keyboard for the user but I'm worried about breaking backwards compatability. What I'm hoping is that browsers/phone that support this can assist the user and other browser will fall back to a standard text field? Is this an acceptable practice? Does it even work?

  • Perl : get substring which matches refex error

    - by Michael Mao
    Hi all: I am very new to Perl, so please bear with my simple question: Here is the sample output: Most successful agents in the Emarket climate are (in order of success): 1. agent10896761 ($-8008) 2. flightsandroomsonly ($-10102) 3. agent10479475hv ($-10663) Most successful agents in the Emarket climate are (in order of success): 1. agent10896761 ($-7142) 2. agent10479475hv ($-8982) 3. flightsandroomsonly ($-9124) I am interested only in agent names as well as their corresponding balances, so I am hoping to get the following output: agent10896761 -8008 flightsandroomsonly -10102 agent10479475hv -10663 agent10896761 -7142 agent10479475hv -8982 flightsandroomsonly -9124 For later processes. This is the code I've got so far: #!/usr/bin/perl -w open(MYINPUTFILE, $ARGV[0]); while(<MYINPUTFILE>) { my($line) = $_; chomp($line); # regex match test if($line =~ m/agent10479475/) { if($line =~ m/($-[0-9]+)/) { print "$1\n"; } } if($line =~ m/flightsandroomsonly/) { print "$line\n"; } } The second regex match has nothing wrong, 'cause that is printing out the whole line. However, for the first regex match, I've got some other output such like: $ ./compareResults.pl 3.txt 2. flightsandroomsonly ($-10102) 0479475 0479475 3. flightsandroomsonly ($-9124) 1. flightsandroomsonly ($-8053) 0479475 1. flightsandroomsonly ($-6126) 0479475 If I "escape" the braces like this if($line =~ m/\($-[0-9]+\)/) { print "$1\n"; } Then there is never a match for the first regex... So I stuck with a problem of making that particular regex work. Any hints for this? Many thanks in advance.

  • inserting new relationship data in core-data

    - by michael
    My app will allow users to create a personalised list of events from a large list of events. I have a table view which simply displays these events, tapping on one of them takes the user to the event details view, which has a button "add to my events". In this detailed view I own the original event object, retrieved via an NSFetchedResultsController and passed to the detailed view (via a table cell, the same as the core data recipes sample). I have no trouble retrieving/displaying information from this "event". I am then trying to add it to the list of MyEvents represented by a one to many (inverse) relationship: This code: NSManagedObjectContext *context = [event managedObjectContext]; MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; [myEvents addEventObject:event];//ERROR And this code (suggested below): //would this add to or overwrite the "list" i am attempting to maintain NSManagedObjectContext *context = [event managedObjectContext]; MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; NSMutableSet *myEvent = [myEvents mutableSetValueForKey:@"event"]; [myEvent addObject:event]; //ERROR Bot produce (at the line indicated by //ERROR): *** -[NSComparisonPredicate evaluateWithObject:]: message sent to deallocated instance Seems I may have missed something fundamental. I cant glean any more information through the use of debugging tools, with my knowledge of them. 1) Is this a valid way to compile and store an editable list like this? 2) Is there a better way? 3) What could possibly be the deallocated instance in error? -- I have now modified the Event entity to have a to-many relationship called "myEvents" which referrers to itself. I can add Events to this fine, and logging the object shows the correct memory addresses appearing for the relationship after a [event addMyEventObject:event];. The same failure happens right after this however. I am still at a loss to understand what is going wrong. This is the backtrace #0 0x01f753a7 in ___forwarding___ () #1 0x01f516c2 in __forwarding_prep_0___ () #2 0x01c5aa8f in -[NSFetchedResultsController(PrivateMethods) _preprocessUpdatedObjects:insertsInfo:deletesInfo:updatesInfo:sectionsWithDeletes:newSectionNames:treatAsRefreshes:] () #3 0x01c5d63b in -[NSFetchedResultsController(PrivateMethods) _managedObjectContextDidChange:] () #4 0x0002e63a in _nsnote_callback () #5 0x01f40005 in _CFXNotificationPostNotification () #6 0x0002bef0 in -[NSNotificationCenter postNotificationName:object:userInfo:] () #7 0x01bbe17d in -[NSManagedObjectContext(_NSInternalNotificationHandling) _postObjectsDidChangeNotificationWithUserInfo:] () #8 0x01c1d763 in -[NSManagedObjectContext(_NSInternalChangeProcessing) _createAndPostChangeNotification:withDeletions:withUpdates:withRefreshes:] () #9 0x01ba25ea in -[NSManagedObjectContext(_NSInternalChangeProcessing) _processRecentChanges:] () #10 0x01bdfb3a in -[NSManagedObjectContext processPendingChanges] () #11 0x01bd0957 in _performRunLoopAction () #12 0x01f4d252 in __CFRunLoopDoObservers () #13 0x01f4c65f in CFRunLoopRunSpecific () #14 0x01f4bc48 in CFRunLoopRunInMode () #15 0x0273878d in GSEventRunModal () #16 0x02738852 in GSEventRun () #17 0x002ba003 in UIApplicationMain () solution I managed to get to the bottom of this. I was fetching the event in question using a NSFetchedResultsController with a NSPredicate which I was releasing after I had the results. Retrieving values from the entities returned was no problem, but when I tried to update any of them it gave the error above. It should not have been released. oustanding part of my question What is a good way to create this sub list from a list of existing items in terms of a core data model. I don't believe its any of the ways I tried here. I need to show/edit it in another table view. Perhaps there is a better way than a boolean property on each event entity? The relationship idea above doesn't seem to work here (even though I can now create it). Cheers.

  • Best way to implement refusing a value change by the user in Swing?

    - by Michael Borgwardt
    I have a JCheckBox that should not be checked by the user when a certain other field is empty. So now I want to have an error popup and then reset the checkbox (I've considered disabling the checkbox, but the connection to the other field is non-obvious, and a tooltip text IMO not visible enough). What's the correct way to do that in Swing? Through a PropertyVetoException? Where do I throw it and where do I catch it? My first (probably ugly) idea would be to add a ChangeListener that itself shows the popup and resets the value.

  • Add blank cell at end of UITable

    - by Michael
    I'm trying to add an additional cell for custom content as the last cell in a tableView, without altering the dictionary that creates the other content of the table. I think the place to add it is in cellForRowAtIndexPath rather than adding one to the numberOfRowsInSection, which just crashes if I do. I get a cellCount from the dictionary that creates the data for the table, then in cellForRowAtIndexPath, I have: if (indexPath.row == cellCount) { ... stuff goes here return cell; } of course, this never gets called. If I do if (indexPath.row == cellCount -1) it overwrites the last cell with content. I can get this to work if I add a blank entry into the xml from which I am populating the dictionary, but that's ugly. Example code would be neat!

  • MVC Entity Framework: Cannot open user default database. Login failed.

    - by Michael
    This type of stuff drives me nuts. I'm having trouble finding the exact issue that I'm having, maybe I just don't know the terminology. Anyway, I had a working website using MVC and Entity Framework, but then I coded an error in a partial view page (ascx). Then all of a sudden I started to get this message. Cannot open user default database. Login failed. Login failed for user 'NT AUTHORITY\SYSTEM' I've found plenty of suggestions about opening SQL Server Management Studio, Double Click on Security, Double Click on Logins, Double click on NT AUTHORITY\SYSTEM and then double click on User Mapping. In this view I'm suppose to check the box for my database so that this user is mapped to this login. However, since I created my database in Visio Studio 2008 as part of my solution, it doesn't show up to allow me to click on it. So what do I do now? What drives me nuts is that everything was working fine. I was using my computer name to access the website and everything was working fine until the coding error. I've fix the error but still getting the error. I should also mention that this error started yesterday too around the same time but later cleared itself up. If I use localhost to access the site, it works just fine. IIS7 configuration for my website: Application Pool = DefaultAppPool Physical Path Credentials Logon = ClearText With in connection strings. I do see the one for my database in this solution. Entry Type is local metadata=res://*/Models.DataModel.csdl|res://*/Models.DataModel.ssdl|res://*/Models.DataModel.msl; provider=System.Data.SqlClient; provider connection string="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\FFBall.mdf;Integrated Security=True;User Instance=True;MultipleActiveResultSets=True" And somewhere I remember changing the identity from Network Service to LocalSystem. Because when I first stared I was getting this same message, but I changed this value and it started working. I saw that suggested somewhere too but I do not recall. Wait I remember now, I believe in IIS7, under Application Pools, DefaultAppPool identity is set to LocalSystem. Additional things I've tried. Restart the computer Recycle the application pool. Antivirus isn't running. Any help would be appreciated. Thank you in advance.

  • Is there a way to use the OSX cocoa NSApplication method activateIgnoringOtherApps: to activate an a

    - by Michael Minerva
    This may be a dumb question but it seems like activateIgnoringOtherApps: may be the only way to activate an app using Cocoa. I have a java app that loads up a Cocoa app and I want the Cocoa app to be activated when this happens. The problem is I do not want to have to launch an intermediate app (some sort of controller) and use this app to activateIgnoringOtherApps: my other Cocoa app. Is there some way to use activateIgnoringOtherApps: to force my Cocoa app to become active?

  • Using PHP session_id() to Make Sure iframe is Generated by Our Server Dynamically

    - by Michael Robinson
    We use iframes to show ads on our site. Iframes are used to allow us to keep the ad generation code and other site modules separate. As we track ad views on our site, and need to be able to keep an accurate count of which pagetype gets what views, I must ensure that users can't simply copy-paste the iframe in which the ad is loaded onto another site. This would cause ad count to become inflated for this page, and the count would not match the view count of the page the iframe "should" be displayed in. Before anyone says so: no I can't simply compare the page view count with the ad view count, or use the page view count * number of ads per page, as # of ads per page will not necessarily be static. I need to come up with a solution that will allow ads to be shown only for iframes that are generated dynamically and are shown on our pages. I am not familiar with PHP sessions, but from what little reading I have had time to do, the following seems to be to be an acceptable solution: Add "s = session_id()" to the src of the ad's iframe. In the code that receives and processes ad requests, only return (and count) and ad if s == session_id(). Please correct me if I'm wrong, but this would ensure: Ads would only be returned to iframes whose src was generated alongside the rest of the page's content, as is the case during normal use. We can return our logo to ad calls with an invalid session_id. So a simple example would be: One of our pages: <?php session_start(); ?> <div id="someElement"> <!-- EVERYONE LOVES ADS --> <iframe src="http//awesomesite.com/ad/can_has_ad.php?s=<?php echo session_id(); ?>></iframe> </div> ad/can_has_ad.php: <?php session_start(); ?> if($_GET['s'] == session_id()){ echo 'can has ad'; } else{ echo '<img src="http://awesomesite.com/images/canhaslogo.jpg"/>'; } And finally, copied code with static 's' parameter: <!-- HAHA LULZ I WILL SCREW WITH YOUR AD VIEW COUNTS LULZ HAHA --> <iframe src="http//awesomesite.com/ad/can_has_ad.php?s=77f2b5fcdab52f52607888746969b0ad></iframe> Which would give them an iframe showing our awesome site's logo, and not screw with our view counts. I made some basic test cases: two files, one that generates the iframe and echos it, and one that the iframe's src is pointed to, that checks the 's' parameter and shows an appropriate message depending on the result. I copied the iframe into a file and hosted it on a different server, and the correct message was displayed (cannot has ad). So, my question is: Would this work or am I being a PHP session noob, with the above test being a total fluke? Thanks for your time! Edit: I'm trying to solve this without touching the SQL server

  • Where is the taglib definition of PrimeFaces 4?

    - by Michael Wölm
    I am looking around how to define custom components in JSF. According to the Java EE tutorial, any custom component needs to be described in a taglib. When I take a look into the PrimeFaces source, I cannot find any taglib file or any hint where the namespace is bound and the available components are defined. I am adding primefaces jar to my dependencies, adding xmlns:p="http://primefaces.org/ui to the xml namespace, defining some primfaces components on my page and it works... Ok, but neither I can find the related taglib in the source or binary package nor my IDE (IntelliJ) is able to find where "xmlns:p="http://primefaces.org/ui" is pointing to. Therefore, code completion is also not possible. (all other mojarra taglibs are found.) Is it possible that PrimeFaces is defining the taglib via annotations directly in Java classes or is it generating it during runtime? I can easily find the UIComponents, primefaces defines in its source, but the configuration of the taglib seems to be missing. I am sure I just don't know how PrimeFaces is doing it, but the javaeetutorial is not describing any other opportunity than defining a ...-taglib.xml

  • How can I make a single WCF method ConcurrencyMode.Multiple when service is ConcurencyMode.Single

    I have a service which is defined as ConcurrencyMode.Single: [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Single, UseSynchronizationContext = false, InstanceContextMode = InstanceContextMode.PerSession, IncludeExceptionDetailInFaults = true)] public class MyService : IMyService This service provides a method to tell the client what it's currently working on: [OperationContract] string GetCurrentTaskDescription(); Is there a way to make this particular method allowable while another long-running task is running where all other methods still follow the single-threaded concurrency model?

  • what makes a Tomcat5.5 cannot be "aware" of new Java Web Applications?

    - by Michael Mao
    This is for uni homework, but I reckon it is more a generic problem to the Tomcat Server(version 5.5.27) on my uni. The problem is, I first did a skeleton Java Web Application (Just a simple Servlet and a welcome-file, nothing complicated, no lib included) using NetBeans 6.8 with the bundled Tomcat 6.0.20 (localhost:8084/WSD) Then, to test and prove it is "portable" and "auto-deploy-able", I cleaned and built a WSD.war file and dropped it onto my Xampp Tomcat (localhost:8080/WSD). The war extracted everything accordingly and I can see identical output from this Tomcat. So far, so good. However, after I tried to drop to war onto uni server, funny thing happens: uni server Even though I've changed the war permission to 755, it is simply not "responding". I then copied the extracted files to uni server, the MainServlet cannot be recognized from within its Context Path "/WSD", basically nothing works, expect the static index.jsp. I tried several times to stop and restart uni Tomcat, it doesn't help? I wonder what makes this happen? Is there anything I did wrong with my approach? To be frank I paid no attention to a server not under my control, and I am unfortunately not a real active day-to-day Java Programmer now. I understand the fundamentals of MVC, Servelets, JSPs, JavaBeans, but I really feel frustrated by this, as I cannot see why... Or, should I ask, a Java Web Application, after cleaned and built by NetBeans6.8, is self-contained and self-configured so ready to be deployed to any Java Web Container? I know, I can certainly program everything in plain old JSP, but this is soooo... unacceptable to myself... Update : I am now wondering if there is any free Tomcat Hosting so that I would like to see if my war file and/or my web app can go with them without any configuration at all?

  • Easy way to add multiple existing .csproj to a Visual Studio Solution?

    - by Michael J Swart
    I've checked out a branch of C# code from source control. It contains maybe 50 projects in various folders. There's no existing .sln file to be found. I intended to create a blank solution to add existing solutions. The UI only lets me do this one project at a time. Is there something I'm missing? I'd like to specify a list of *.csproj files and somehow come up with a .sln file that contains all the projects.

  • jQuery code in ajax loaded content only runs once

    - by Michael Howland
    I have been looking around SO for a while and haven't been able to find anything that matches my issue, which I'm not even sure I can explain that well, so take that for what it's worth. I have a page that loads content into a div via AJAX (using the .load() method). There are several links in the navigation, meaning the content will change while navigating the site without refreshing the entire page. (Actually, to be honest, I just cribbed the DocTemplate layout [http://css-tricks.com/examples/DocTemplate/] from css-tricks.com. Apparently while I'm not a re-invent the wheel type programmer, I am a bash my head against the wheel incessantly to get it to work programmer.) So, index.php loads up some DB content in a div. There is also a jQuery UI modal input form on index.php. Essentially, the only HTML on the page is an empty div and a form. This all works fine, until I call up another page, then go back to index.php. The DB content is not loaded, and my form is shown there in all its naked glory. I know why this is happening. The page was not refreshed, nothing kicked off the code to load the content and hide the form. My question is, how can I ensure that the AJAX .load() and the .dialog() will run when loading index.php again? Is it even possible? Thanks, and my apologies for the length. I get verbose when I'm confused.

  • Using javascript on an HTML table?

    Hi, few questions, just wondering if anyone can help? I have a table with 1 long row (1000 pixels) and one single column, how do i go about creating a method whereby when the mouse cursor is on the leftmost side of the cell, a variable, lets say X is set to 0, the further right the mouse cursor moves in the cell, the value of X increases. I know that sounds like a strange question but im working on a project where this type of functionality is desired. Is there a javascript method to create this feature? Thanks for any help.

  • CSS [custom?] attributes

    - by Michael
    radio[pane] { list-style-image: url("jar:resource:///chrome/classic.jar! /skin/classic/browser/preferences/Options.png"); } radio[pane="prefpane-appearance"] { -moz-image-region: rect(0px, 32px, 32px, 0px); } radio[pane="prefpane-appearance"]:hover, radio[pane="prefpane-appearance"][selected="true"] { -moz-image-region: rect(32px, 32px, 64px, 0px); } Can anyone explain a syntax of this css, particularly what is pane.. I couldn't find such attribute for radio element in context of XUL. So I guess it's some custom attribute? If it is, then how it is evolving through the lines, first declaration, then several assignments? It has also selected, which means can have multiple custom attributes? How can those attributes be used later?

  • php preg_match pattern to extract a specific information, regex

    - by Michael
    I need to extract a specific Id from a html document but the problem is that the id must not "be used". Here is the html content http://pastebin.com/wF2dx8JZ As you may see there are different html blocks . Some of them contain the "Used" word so I need to extract only the first id which is not used. Basically I can write a simple pattern like : $pattern = "/javascript:tw(.*))/"; preg_match_all($pattern, $content, $matches); $id = $matches[1][0]; However in this case I'm also getting the "ids" which are used so I don't know how to exclude them from the equation . Any idea would be highly appreciated.

  • Custom class object in Initialization list

    - by Michael
    I have a class Bar: class Bar { public: Bar(void); ~Bar(void); }; And a class Foo that gets a reference to Bar object as a constructor parameter and needs to save it in a private member bar_ : class Foo { private: Bar& bar_; public: Foo(Bar& bar) : bar_(bar) {} ~Foo(void) {} }; This doesn't compile : overloaded member function not found in 'Parser' missing type specifier - int assumed. Note: C++ does not support default-int Now i suspect couple of things that i need to assure, the second error is for Bar& bar_; declaration in Foo. Do i need to use an explicit constructor when declaring bar_ ? I am interested in learning how the compiler works regarding this matter, so a detailed explanation would be highly appreciated. Thanks.

  • Can you set a gradient brush for a listboxitem background in silverlight?

    - by Michael
    I am looking for a way to set a gradientbrush as the background for a listbox item. I have a DataTemplate defined and have specified a gradient brush but it always appears as the listbox background (i.e. it never shows as a gradient brush). I have been able to set the background of the listbox itself, and I can set the listboxitem's background to a standard color using the "setter" object....but none of these are what I am after. I really want the background on each list item to be a gradient brush. Below is the datatemplate that I have constructed. <ListBox Name="MyListBox" Margin="12,67,12,169"> <ListBox.ItemTemplate> <DataTemplate> <Grid Height="51" VerticalAlignment="Bottom"> <Grid.Background> <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"> <GradientStop Color="#FFC9F4D0"/> <GradientStop Color="#FF2AC12A" Offset="0.333"/> <GradientStop Color="#FF35DE35" Offset="1"/> </LinearGradientBrush> </Grid.Background> <Canvas > <dataInput:Label Width="227" Foreground="Yellow" Canvas.Left="158" Canvas.Top="8" Content="{Binding Place}"/> <dataInput:Label Width="146" Foreground="Yellow" Canvas.Left="8" Canvas.Top="8" Content="{Binding Date}"/> <dataInput:Label Content="{Binding People}" Width="346" FontSize="9.333" Foreground="Black" Canvas.Left="166" Canvas.Top="28"/> <!-- <dataInput:Label Width="45" Content="Accept" Foreground="White" Canvas.Left="8" Canvas.Top="28"/> <dataInput:Label Width="45" Content="Decline" Foreground="White" Canvas.Left="57" Canvas.Top="28"/> --> <dataInput:Label Content="SomeText" Width="101" FontSize="9.333" Foreground="White" Canvas.Left="389" Canvas.Top="10"/> <Image Height="21" Width="21" Canvas.Left="500" Canvas.Top="8" Source="Green Button.png"/> </Canvas> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox> Any Thoughts?

  • Why is Perl commonly used as CGI scripts?

    - by Michael Vasquez
    I plan to add a better search feature to my site, so I thought that I would write it in C and use the CGI as a means to access it. But it seems that Perl is the most popular language when it comes to CGI-based stuff. Why is that? Wouldn't it be faster programmed in C or machine code? What advantages, if any, are there to writing it in a scripting language? Thanks.

  • Can Visual Studio 2010 Test .net 3.5 SP1 Projects?

    - by Michael Stum
    I have some projects in a solution that are running on .net 3.5 SP1 (and can never ever be updated to 4.0 as they are SharePoint projects). When I try to create a new Visual C# Test Project in VS2010 Premium, I have to choose .net 4.0 which is apparently intended. Now I don't care about what my Unit Test project is (don't have to care about VS2008 users), but I do care if I can safely test 3.5 Projects in it due to the different CLRs and slight C# language differences?

  • How much do politics/office intrigue interfere with your day to day tasks at work?

    - by Michael Dorgan
    I'm currently blessed to be employed at a location where politics are pretty much non-existant and management overhead is nearly nil. As I've only worked at this one location for my entire, lengthy career, I have very little frame of reference outside of an occasional Dilbert comic or offhand comment from others about just how bad office politics and management interference get in the way of getting your code done elsewhere. While I'm not actively looking for a new job, this one point has made me quite reluctant to even look seriously elsewhere. My question is, just how much are politics a way of life in larger companies - in or out of the game industry and how much does it affect your day to day satisfaction?
