• Adding a button bar at the bottom of ListView upon checkbox select (as in gmail app)??

  - by elto

  I have a ListView with custom adapter. In each row there is a checkbox and couple of textviews. I want user to give option to delete the check marked items, so as soon as soon clicks on one of the checkbox, I want a button bar to slide in from the bottom and stay at the bottom regardless of listview scroll. This is something like the email app behavior of Motorola Cliq and to some extent gmail app itself. I have tried adding a relativelayout (containing buttons) below the listview, which has visibility set to gone initially, but as soon as user checks a button, the visibility changes to "visible". I have added a slide-in animation to it too. It is working but problem is that it is overlapping the last element of the listview which user can not checkmark if the button bar has already become visible. So I tried to set the bottom margin of the listview equal to the height of the button bar when I'm changing the button bar visibility, which solves the problem of overlap, but now the checkbox behavior has gone weird. Clicking on one checkmark tries to checkmark another checkmark in the list for some weird reason. I noticed that this happens because as soon as I change the listview margin, list redraws itself, and during this new call to getView() method of adapter, things mess up. I wanted to ask if anyone has done something like this. What is the best method to add such button bar below list while keeping the slide-in animation intact. Also, What is the footer-view of listview and can that solve my problem?

• How to determine a text block of a file in one version come from which file in the previous version?

  - by Muhammad Asaduzzaman

  The problem is described below: Suppose I have a list of files in one version(say A,B,C,D). In the next version I have the following files(A,E,F,G). There are some similarities in their contents. The files in the later version comes from the previous version by file name renaming, content addition, deletion or partial modification or without any change( for example A is not changed). I take a block of text from a file(E, 2nd version) and check which files(in the 1st version) contain this text block. I found that B,C and D contain the text fragment. I want to determine from which file(B or c or d) this text block actually comes from.(I assume that E is a file whose name change in the second version). Since the contents may be changed, added or deleted in the later version, so in order to determine similarity I use LCS algorithm. But I cannot map the file with its previous version. I think one possible approach might be to use the location information of the match text blocks. But this heuristics not always work. Is there any research or algorithm exist to find so. Any direction will be helpful. Thanks in advance.

• How to handle building and parsing HTTP URL's / URI's / paths in Perl

  - by Robert S. Barnes

  I have a wget like script which downloads a page and then retrieves all the files linked in img tags on that page. Given the URL of the original page and the the link extracted from the img tag in that page I need to build the URL for the image file I want to retrieve. Currently I use a function I wrote: sub build_url { my ( $base, $path ) = @_; # if the path is absolute just prepend the domain to it if ($path =~ /^\//) { ($base) = $base =~ /^(?:http:\/\/)?(\w+(?:\.\w+)+)/; return "$base$path"; } my @base = split '/', $base; my @path = split '/', $path; # remove a trailing filename pop @base if $base =~ /[[:alnum:]]+\/[\w\d]+\.[\w]+$/; # check for relative paths my $relcount = $path =~ /(\.\.\/)/g; while ( $relcount-- ) { pop @base; shift @path; } return join '/', @base, @path; } The thing is, I'm surely not the first person solving this problem, and in fact it's such a general problem that I assume there must be some better, more standard way of dealing with it, using either a core module or something from CPAN - although via a core module is preferable. I was thinking about File::Spec but wasn't sure if it has all the functionality I would need.

• SQL Server error handling: exceptions and the database-client contract

  - by gbn

  We’re a team of SQL Servers database developers. Our clients are a mixed bag of C#/ASP.NET, C# and Java web services, Java/Unix services and some Excel. Our client developers only use stored procedures that we provide and we expect that (where sensible, of course) they treat them like web service methods. Some our client developers don’t like SQL exceptions. They understand them in their languages but they don’t appreciate that the SQL is limited in how we can communicate issues. I don’t just mean SQL errors, such as trying to insert “bob” into a int column. I also mean exceptions such as telling them that a reference value is wrong, or that data has already changed, or they can’t do this because his aggregate is not zero. They’d don’t really have any concrete alternatives: they’ve mentioned that we should output parameters, but we assume an exception means “processing stopped/rolled back. How do folks here handle the database-client contract? Either generally or where there is separation between the DB and client code monkeys. Edits: we use SQL Server 2005 TRY/CATCH exclusively we log all errors after the rollback to an exception table already we're concerned that some of our clients won't check output paramaters and assume everything is OK. We need errors flagged up for support to look at. everything is an exception... the clients are expected to do some message parsing to separate information vs errors. To separate our exceptions from DB engine and calling errors, they should use the error number (ours are all 50,000 of course)

• KnockoutJS - creating object doesn't work

  - by Kiwanax

  I'm doing a navigation list with menus and submenus. I have the following structure: function Menu(navigation) { this.NavigationUrl = ko.observable(navigation.NavigationUrl); this.NavigationTitle = ko.observable(navigation.NavigationTitle); this.NavigationDescription = ko.observable(navigation.NavigationDescription); var mappedChildren = ko.utils.arrayMap(navigation.Children, function (child) { return new Menu(child); }); this.Children = ko.observableArray(mappedChildren); } function DashboardViewModel() { var self = this; self.LoggedUser = ko.observable(""); self.Navigations = ko.observableArray([]); $.get('/Home/DashboardDependencies', {}, function (result) { self.LoggedUser(result.LoggedUser); var mappedNavigations = ko.utils.arrayMap(result.Navigations, function (item) { var menu = new Menu(item); // When I alert item, the result appears properly: // { "NavigationTitle": "blah", "NavigationDescription": "bleh" [...] } alert(JSON.stringify(item)); // But when I alert the new menu object, the result doesn't appear: // Just: "{}" alert(JSON.stringify(menu)); return menu; }); self.Navigations = mappedNavigations; }); } ko.applyBindings(new DashboardViewModel()); So, check it out. When I try to alert the item variable, the result appears properly. When I try to alert the new Menu object, the result just show {}. Why this' happening? Thank you all for the help!

• Stuck trying to get Log4Net to work with Dependency Injection

  - by Pure.Krome

  I've got a simple winform test app i'm using to try some Log4Net Dependency Injection stuff. I've made a simple interface in my Services project :- public interface ILogging { void Debug(string message); // snip the other's. } Then my concrete type will be using Log4Net... public class Log4NetLogging : ILogging { private static ILog Log4Net { get { return LogManager.GetLogger( MethodBase.GetCurrentMethod().DeclaringType); } } public void Debug(string message) { if (Log4Net.IsDebugEnabled) { Log4Net.Debug(message); } } } So far so good. Nothing too hard there. Now, in a different project (and therefore namesapce), I try and use this ... public partial class Form1 : Form { public Form1() { FileInfo fileInfo = new FileInfo("Log4Net.config"); log4net.Config.XmlConfigurator.Configure(fileInfo); } private void Foo() { // This would be handled with DI, but i've not set it up // (on the constructor, in this code example). ILogging logging = new Log4NetLogging(); logging.Debug("Test message"); } } Ok .. also pretty simple. I've hardcoded the ILogging instance but that is usually dependency injected via the constructor. Anyways, when i check this line of code... return LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType); the DeclaringType type value is of the Service namespace, not the type of the Form (ie. X.Y.Z.Form1) which actually called the method. Without passing the type INTO method as another argument, is there anyway using reflection to figure out the real method that called it?

• Multiple Facebook scripts?

  - by J Set

  This may be kind of a dumb question, but the script for the facebook button on the like button page is different from the script on the javascript sdk page, but similar. Did facebook just forget to update the documentation or do I need both scripts? The like button page gives: <div id="fb-root"></div> <script> (function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/en_US/all.js#xfbml=1"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script> But on the javascript sdk page: <div id="fb-root"></div> <script> window.fbAsyncInit = function() { FB.init({ appId : 'YOUR_APP_ID', // App ID channelUrl : '//WWW.YOUR_DOMAIN.COM/channel.html', // Channel File status : true, // check login status cookie : true, // enable cookies to allow the server to access the session xfbml : true // parse XFBML }); // Additional initialization code here }; // Load the SDK Asynchronously (function(d){ var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0]; if (d.getElementById(id)) {return;} js = d.createElement('script'); js.id = id; js.async = true; js.src = "//connect.facebook.net/en_US/all.js"; ref.parentNode.insertBefore(js, ref); }(document)); </script>

• Surely a foolish error, but I can't see it

  - by dnagirl

  I have a form (greatly simplified): <form action='http://example.com/' method='post' name='event_form'> <input type='text' name='foo' value='3'/> <input type='submit' name='event_submit' value='Edit'/> </form> And I have a class "EventForm" to process the form. The main method, process() looks like this: public function process($submitname=false){ $success=false; if ($submitname && isset($_POST[$submitname])){ //PROBLEM: isset($_POST[$submitname] is always FALSE for some reason if($success=$this->ruler->validate()){//check that dependancies are honoured and data types are correct if($success=$this->map_fields()){//divide input data into Event, Schedule_Element and Temporal_Expression(s) $success=$this->eventholder->save(); } } } else {//get the record from the db based on event_id or schedule_element_id foreach($this->gets as $var){//list of acceptable $_GET keys if(isset($_GET[$var])){ if($success= $this->__set($var,$_GET[$var])) break; } } } $this->action=(empty($this->eventholder->event_id))? ADD : EDIT; return $success; } When the form is submitted, this happens: $form->process('event_submit'); For some reason though, isset($_POST['event_submit']) always evaluates to FALSE. Can anyone see why?

• How to speed-up python nested loop?

  - by erich

  I'm performing a nested loop in python that is included below. This serves as a basic way of searching through existing financial time series and looking for periods in the time series that match certain characteristics. In this case there are two separate, equally sized, arrays representing the 'close' (i.e. the price of an asset) and the 'volume' (i.e. the amount of the asset that was exchanged over the period). For each period in time I would like to look forward at all future intervals with lengths between 1 and INTERVAL_LENGTH and see if any of those intervals have characteristics that match my search (in this case the ratio of the close values is greater than 1.0001 and less than 1.5 and the summed volume is greater than 100). My understanding is that one of the major reasons for the speedup when using NumPy is that the interpreter doesn't need to type-check the operands each time it evaluates something so long as you're operating on the array as a whole (e.g. numpy_array * 2), but obviously the code below is not taking advantage of that. Is there a way to replace the internal loop with some kind of window function which could result in a speedup, or any other way using numpy/scipy to speed this up substantially in native python? Alternatively, is there a better way to do this in general (e.g. will it be much faster to write this loop in C++ and use weave)? ARRAY_LENGTH = 500000 INTERVAL_LENGTH = 15 close = np.array( xrange(ARRAY_LENGTH) ) volume = np.array( xrange(ARRAY_LENGTH) ) close, volume = close.astype('float64'), volume.astype('float64') results = [] for i in xrange(len(close) - INTERVAL_LENGTH): for j in xrange(i+1, i+INTERVAL_LENGTH): ret = close[j] / close[i] vol = sum( volume[i+1:j+1] ) if ret > 1.0001 and ret < 1.5 and vol > 100: results.append( [i, j, ret, vol] ) print results

• Reload images in a UIWebView after they have been downloaded by a background thread

  - by dantastic

  I have an application that frequently checks in with a server and downloads a batch of articles to the iphone. The articles are in html and just stored using core data. An article has 0-n images on the page. Downloading all associated images at the same time as the text will be too slow and take too much bandwidth. Users are not likely to open every article. If they open an article once it is likely they will open it several times. So I want to download and store the images locally when they are needed. These articles are listed in a UITableView. When you tap an article you pop open a UIWebView that displays the article. I have a function that checks if I have downloaded the images associated with the article already. If I have I just pop open the the UIWebView - everything works fine. If I don't have the images downloaded I go off and download them and store them to my Documents directory. Although this i working, the app is hanging while the images are downloading. Not very tidy. I want the article to open in a snap and download the images with the article open. So what I've done is I check if the images are downloaded, if they aren't I go ahead and just "touch" the files I need and load the webview. The UIWebView opens up but the images referenced contain no data. Then in a background thread I download the images and overwrite the "dummy" ones. This will save the images and everything but it won't reload the images in my current UIWebView. I have to go back out of the article back back in again to see the images. Are there any ways around this? reloading just an image in a UIWebView?

• Initialize listitem with blanks?

  - by VBartilucci

  Say I have a list made up of a listitem which contains three strings. I add a new listitem, and try to assign the values of said strings from an outside source. If one of those items is unassigned, the value in the listitem remains as null (unassigned). As a result I get an error if I try to assign that value to a field on my page. I can do a check on isNullOrEmpty for each field on the page, but that seems inefficient. I'd rather initialize the values to "" (Empty string) in the codebehind and send valid data. I can do it manually: ClaimPwk emptyNode = new ClaimPwk(); emptyNode.cdeAttachmentControl = ""; emptyNode.cdeRptTransmission = ""; emptyNode.cdeRptType = ""; headerKeys.Add(emptyNode); But I have some BIG list items, and writing that for those will get tedious. So is there a command, or just plain an easier way to initialize a listitem to empty string as opposed to null? Or has anyone got a better idea?

• WPF - Extend ListView with checkable AND selectable ListViewItems

  - by Marks

  Hi there. I already read many examples on extending ListViews with checkboxes bound with IsSelected. But I want something more. I want a seperation between the checked and selected state, so i get a ListBox that has a single selected item, but can have multiple checked items. Unfortunately ListViewItem does not have a property for checked and I dont see a possibility to get the ListView to work with a custom CheckableListViewItem. Of course i could use a List of objects with a checked property as ItemSource, but I dont think thats a good way to go. Checked or not is a matter of the list or item-container, not of the object listed in it. Beside that I dont want all my classes like user, role, group to have counterparts like checkableUser, checkableRole and checkableGroup. The behaviour i want can be easyly accomblished for the UI with a <DataTemplate x:Key="CheckBoxCell"> <StackPanel Orientation="Horizontal"> <CheckBox /> </StackPanel> </DataTemplate> and a <GridViewColumn CellTemplate="{StaticResource CheckBoxCell}" Width="30"/> But without a binding on the checkbox i cant check if it is checked or not. Is there any way to accomplish something like that? The perfect solution for me would be to have listView1.SelectedItem, listView1.CheckedItems and maybe a listView1.UncheckedItems and of course listView1.CheckItem and listView1.UncheckItem. Thanks for any help.

• How to make categories and current page highlighting in PHP?

  - by Markus Ossi

  I am trying to find some example code or best practices about making CMS-type categories with PHP. This is a problem that has for sure been solved gazillion times but for some reason I am unable to find any example code using PHP about how to implement this. As far as I can tell, there are two parts to the problem. The first one has to with the styling side of things: outputting the link in the navigation so that the current page has a special style (class="active") and to not print out the link for the current page. The second part is handling categories, subcategories and the dynamic pages under the categories. The second part seems pretty straightforward. I am thinking of making it so that the name of the category in the navigation is a link to categories.php?id=x and on this page I just print out the pages with that category id. Then, if the user klicks on a page he will be taken to pages.php?id=y. However, I am not quite sure on how to make a navigation to check if we are now on the current page. Should I just use some case switch or what? Any ideas or links to some good example code are much appreciated.

• java url connection, wait for data being sent through the outputstream

  - by Mateu

  I'm writting a java class that tests uploading speed connection to a server. I want to check how many data can be send in 5 seconds. I've written a class which creates a URL, creates a connection, and sends data trough the outPutStream. There is a loop where I writte data to the stream for 5 seconds. However I'm not able to see when data has been send (I writte data to the output stream, but data is not send yet). How can I wait untill data is really sent to the server? Here goes my code (which does not work): URL u = new URL(url) HttpURLConnection uc = (HttpURLConnection) u.openConnection(); uc.setDoOutput(true); uc.setDoInput(true); uc.setUseCaches(false); uc.setDefaultUseCaches(false); uc.setRequestMethod("POST"); uc.setRequestProperty("Content-Type", "application/octet-stream"); uc.connect(); st.start(); // Send the request OutputStream os = uc.getOutputStream(); //This while is incorrect cause it does not wait for data beeing sent while (st.getElapsedTime() < miliSeconds) { os.write(buffer); os.flush(); st.addSize(buffer.length); } os.close(); Thanks

• PHP and MySQL echoing out a Table

  - by user1631702

  Okay, so I've done this before, and it worked. I am trying to echo out specific rows on my database in a table. Here is my code: <?php $connect = mysql_connect("localhost", "xxx", "xxx") or die ("Hey loser, check your server connection."); mysql_select_db("xxx"); $quey1="select * from `Ad Requests`"; $result=mysql_query($quey1) or die(mysql_error()); ?> <table border=1 style="background-color:#F0F8FF;" > <caption><EM>Student Record</EM></caption> <tr> <th>Student ID</th> <th>Student Name</th> <th>Class</th> </tr> <?php while($row=mysql_fetch_array($result)){ echo "</td><td>"; echo $row['id']; echo "</td><td>"; echo $row['twitter']; echo "</td><td>"; echo $row['why']; echo "</td></tr>"; } echo "</table>"; ?> It gives me no errors, but It just shows a blank table with none of these rows. My Question: How come this wont show any rows in the table, what am I doing wrong?

• what is a root directory in IIS 6 and How do I make one of my subfolder in ASP.NET website the root directory?

  - by R_Coder

  I need to integrate a third party plugin in my asp.net website. To install the plugin, they have mentioned this sentence, "Create an application through your IIS control panel with root directory at -(some path from my website folder)?". I am not much aware with IIS and rarely worked with it. Though I tried every possible way i could do in IIS, I am not able to work it out. After installation, there is a test page provided by plugin which i have to run to check but when I run it, it shows this error. "It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS." I searched this error too and found that it is because the two Web.Config file, one from the main project and another from plugin folder. The only way to work with this is to make the plugin folder they specified as root directory in IIS. Someone kindly tell me some easy steps to do this. What I was doing is, in IIS6, I added New website with the main folder of my asp.net website, then I right clickadd application and choosed the gievn path, thought it would become root directory but it ain't. Help would be appreciated. ALso note that, i have to put the plugin folder in my main website folder only. So, there are two web.config. I tried to rename one of them too, it solved the above error but gave another errors but I think main problem is of root directory. P.S they show me above error on web.config file of plugin folder on this sentence- "Line 51: < authentication mode="Windows" />"

• Passing a WHERE clause for a Linq-to-Sql query as a parameter

  - by Mantorok

  Hi all This is probably pushing the boundaries of Linq-to-Sql a bit but given how versatile it has been so far I thought I'd ask. I have 3 queries that are selecting identical information and only differ in the where clause, now I know I can pass a delegate in but this only allows me to filter the results already returned, but I want to build up the query via parameter to ensure efficiency. Here is the query: from row in DataContext.PublishedEvents join link in DataContext.PublishedEvent_EventDateTimes on row.guid equals link.container join time in DataContext.EventDateTimes on link.item equals time.guid where row.ApprovalStatus == "Approved" && row.EventType == "Event" && time.StartDate <= DateTime.Now.Date.AddDays(1) && (!time.EndDate.HasValue || time.EndDate.Value >= DateTime.Now.Date.AddDays(1)) orderby time.StartDate select new EventDetails { Title = row.EventName, Description = TrimDescription(row.Description) }; The code I want to apply via a parameter would be: time.StartDate <= DateTime.Now.Date.AddDays(1) && (!time.EndDate.HasValue || time.EndDate.Value >= DateTime.Now.Date.AddDays(1)) Is this possible? I don't think it is but thought I'd check out first. Thanks

• Internal loop only runs once, containing loop runs endlessly

  - by Mark

  noob question I'm afraid. I have a loop that runs and rotates the hand of a clock and an internal loop that checks the angle of the hand if it is 90, 180, 270 and 360. On these 4 angles the corresponding div is displayed and its siblings removed. The hand loops and loops eternally, which is what I want, but the angle check only runs the loop once through the whole 360. As the hand passes through the angles it is correctly displaying and removing divs but is doesn't continue after the first revolution of the clock. I've obviously messed up somewhere and there is bound to be a more efficient way of doing all this. I am using jQueryRotate.js for my rotations. Thanks for your time. jQuery(document).ready(function(){ var angle = 0; setInterval(function(){ jQuery("#hand").rotate(angle); function movehand(){ if (angle == 90) { jQuery("#intervention").fadeIn().css("display","block").siblings().css("display","none"); } else if (angle == 180) { jQuery("#management").fadeIn().css("display","block").siblings().css("display","none"); } else if (angle == 270) { jQuery("#prevention").fadeIn().css("display","block").siblings().css("display","none"); } else if (angle == 360) { jQuery("#reaction").fadeIn().css("display","block").siblings().css("display","none"); } else {movehand;} }; movehand(); angle+=1; },10); });

• [C#] how to do Exception Handling & Tracing

  - by shrimpy

  Hi all, i am reading some C# books, and got some exercise don't know how to do, or not sure what does the question mean. Problem: After working for a company for some time, your skills as a knowledgeable developer are recognized, and you are given the task of “policing” the implementation of exception handling and tracing in the source code (C#) for an enterprise application that is under constant incremental development. The two goals set by the product architect are: 100% of methods in the entire application must have at least a standard exception handler, using try/catch/finally blocks; more complex methods must also have additional exception handling for specific exceptions All control flow code can optionally write “tracing” information to assist in debugging and instrumentation of the application at run-time in situations where traditional debuggers are not available (eg. on staging and production servers). (i am not quite understand these criterias, i came from the java world, java has two kind of exception, check and unchecked exception. Developer must handle checked exception, and do logging. about unchecked exception, still do logging maybe, but most of the time we just throw it. however here comes to C#, what should i do????) Question for Problem: List rules you would create for the development team to follow, and the ways in which you would enforce rules, to achieve these goals. How would you go about ensuring that all existing code complies with the rules specified by the product architect; in particular, what considerations would impact your planning for the work to ensure all existing code complies?

• Webkit browsers rendering CSS different than Mozilla Firefox...Why??

  - by JAG2007

  I'm styling a form that was already marked up (made some markup changes), and I normally work in Firefox to style so I can use firebug and the web developer toolbar. On this project, I noticed that my styles are displaying quite differently for one particular area (several elements) in webkit based browsers Chrome and Safari, than in Firefox (we won't even get into Internet Explorer, although it is siding with the Firefox display). I can't figure out though why the styles are displaying so differently. Normally there is some rule that I'm neglecting that Firefox just takes for granted, and the others need it specified. But here I'm not getting why it's displaying this way. In particular I'm referring to the bottom area of the form where users can enter their contact info, then submit the form. I'll attach screen shots for reference as to the discrepancy. Here's the URL so feel free to check it out on your own. Although be advised that this is a production page (already released) so if you try out the form, you WILL BE added to CURE's contact database. http://www.helpcurenow.org/survey2010 Here's the screen shots: Firefox (the way I intend it to look) Chrome, and then Safari - strange change to submit button As a bonus, if anybody wants to help me with figuring out why on earth IE7 wants to not show the background behind the questions only, and how to fix that I would be much obliged! Thanks very much.

• Remove this URL string when login fails and simply show div error

  - by Anagio

  My developer built our registration page to display a div when logins failed based on a string in the URL. When logins fail this is added to the URL /login?msg=invalid The PHP in my login.phtml which displays the error messages based on the msg= parameter is <?php $msg = ""; $msg = $_GET['msg']; if($msg==""){ $showMsg = ""; } elseif($msg=="invalid"){ $showMsg = ' <div class="alert alert-error"> <a class="close" data-dismiss="alert">×</a> <strong>Error!</strong> Login or password is incorrect! </div>'; } elseif($msg=="disabled"){ $showMsg = "Your account has been disabled."; } elseif($msg==2){ $showMsg = "Your account is not activated. Please check your email."; } ?> In the controller the redirect to that URL is else //email id does not exist in our database { //redirecting back with invalid email(invalid) msg=invalid. $this->_redirect($url."?msg=invalid"); } I know there are a few other validation types for disabled accounts etc. I'm in the process of redesigning the entire interface and would like to get rid of this kind of validation so that the div tags display when logins fail but not show the URL strings. If it matters the new div I want to display is <div class="alert alert-error alert-login"> Email or password incorrect </div> I'd like to replace the php my self in my login.phtml and controller but not a good programmer. What can I replace $this->_redirect($url."?msg=invalid"); with so that no strings are added to the URL and display the appropriate div tags? Thanks

  - by solefald

  I've seen a million of these threads here already, and read through every single one already. Including some serious time Googling. Nothing complicated. All I have to do is check if a single character in a loop matches my alphabet array. print_r($alphabet); // all 26 letters Array ( [0] => a [1] => b [2] => c ... [23] => x [24] => y [25] => z ) print_r($emptyLetters); // dynamic array. Array ( [0] => b [1] => s ) foreach($alphabet as $letter): { echo $letter . '<br />' // Correctly prints out every letter from $alphabet. if(in_array($letter, $emptyLetters, true)): // $strict is set // do something endif; } What the hell is going on??? I do not understand what i am doing wrong.... I tried every combination and option possible, but for some reason even array_search() is bit working...

• Default entries on a first time creation for a serialized class

  - by MGSoto

  I have a class I am using for serializing various configuration options for an application I am working on. I'm adding a new property to the class that is a List, and I'd like it to fill this list if it does not exist already in a XML file. My first thought was to check if the list contained zero items, however this is not acceptable because there are times I want to have zero items in the list. In essence I want a file that has been serialized with an older version of the same class to be "upgraded" and have defaults automatically inserted for new properties. How can I do this? For a more visual example of what I'm trying to do, see below: When I deserialize an XML file that contains: <Item1>wtfe</Item1> <Item2>wtfe</Item2> and after I've added a list property it will serialze as: <Item1>wtfe</Item1> <Item2>wtfe</Item2> <Item3/> I want it to serialize as: <Item1>wtfe</Item1> <Item2>wtfe</Item2> <Item3> <DefaultSubItem/ Field="wtfe"> <DefaultSubItem/ Field="wtfe"> </Item3> But allow me to change it to: <Item1>wtfe</Item1> <Item2>wtfe</Item2> <Item3></Item3>

• How to reference SMF libraries when deploying on phone 7 (Release)

  - by aHaH

  Initially, at Visual Studio, I clicked debug instead of release to deploy my app on phone 7 device. No errors, works perfectly fine! Received multitude of errors that mention that some of the libraries don't seem to exist on the mobile phone. For example, extract from the entire list of errors include Warning 10 The referenced component 'Microsoft.SilverlightMediaFramework.Utilities' could not be found. Warning 3 Could not resolve this reference. Could not locate the assembly "Microsoft.SilverlightMediaFramework.Plugins". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors. SLARToolKitWinPhoneSample In addition, im also using Slartookit to power up the AR capabilities. Deploying (Release) on the mobile prompts the following errors too. Error 11 The type or namespace name 'SLARToolKit' could not be found (are you missing a using directive or an assembly reference?) What should I do? Will updating the mobile solve this? Do I have to manually install? Or? Thanks
