  - by user342391

  I am trying to get a variable on my page to equal the result of a switch I have. This is the code: $payment_method = switch ($cardtype) { case "visa" : echo "VSA"; break; case "mastercard" : echo "MSC"; break; case "maestro" : echo "MAE"; break; case "amex" : echo "AMX" ; break; default : echo "Please specify a payment method!"; break; }; How can I get $payment_method to equal the result of this????

• git status: how to ignore some changes

  - by Mr Fooz

  Is there a way to have git status ignore certain changes within a file? Background I have some files in my repository that are auto-generated (yes, I know that's typically not recommended, but I have no power to change this). Whenever I build my tree, these auto-generated files have status information updated in them (who generated them, a timestamp, etc.). When I say git status, I'd like it to run a filter on these generated files that strips out this transient status information. I only want it to show up in the "Changed but not updated:" section of git's output if there are other, real changes. Using the .gitattributes approach found at http://progit.org/book/ch7-2.html, I am able to get git diff to ignore these status line changes using a simple egrep filter. I'd like to get git status to also use textconv filters (or something equivalent). I'd prefer it if merges aren't affected by any of this filtering.

• Add Today's Date to SharePoint Master Page

  - by soniiic

  Surely there must be a simple way of putting a simple code block into a master page :( I've tried using the obvious <%= "Hello, World!" %> syntax but code blocks aren't allowed. Then tried a site column, but don't know how to use them. Then tried web zones but master pages can't use them. Tried putting a web part (which are super difficult to make and deploy btw) into the page layout, but it just doesn't render :/ All I want is something nice and simple at the top of my site which shows today's date and the format I want to use is DateTime.Today.ToString("ddd, d MMMM yyyy") (Otherwise I'm resorting to javascript document.write!) Thanks all,

• jqGrid - how to change title based on colModel sortable property

  - by Greg

  When the mouse hovers over each column I'd like the tooltip to indicate whether that column is sortable. I am able to change the title attribute with something like this: $("#List .ui-th-column").each(function(i) { var isSortable = i % 2; $(this).attr('title', isSortable ? "Not Sortable" : "Click header to sort."); }); I'd like to replace the demo expression 'i % 2' with a check of the colMode's sortable property, but I can't figure out how to get the value of the colModel's sortable property. colModel: [ { name: 'Name', index: 'Name', width: 100, sortable: true }, { name: 'Note', index: 'Note', width: 200, sortable: false } ] I've tried .getGridParam and .getColProp but I don't think the syntax I'm using is correct.

• How to use Django's filesizeformat

  - by Scott LaPlant

  I have a small app I'm working on where I'm trying to use Django's built in filesizeformat. Currently, the format looks like this: {{ value|filesizeformat }} I understand I need to define this in my view.py file but, I can't seem to figure out how to do that. I've tried to use the syntax below: def filesizeformat(bytes): """ Formats the value like a 'human-readable' file size (i.e. 13 KB, 4.1 MB, 102 bytes, etc). """ try: bytes = float(bytes) except (TypeError,ValueError,UnicodeDecodeError): return u"0 bytes" if bytes < 1024: return ungettext("%(size)d byte", "%(size)d bytes", bytes) % {'size': bytes} if bytes < 1024 * 1024: return ugettext("%.1f KB") % (bytes / 1024) if bytes < 1024 * 1024 * 1024: return ugettext("%.1f MB") % (bytes / (1024 * 1024)) return ugettext("%.1f GB") % (bytes / (1024 * 1024 * 1024)) filesizeformat.is_safe = True I've then replaced 'value' with 'bytes' in the template but, this does not seem to work. Any suggestions?

• OSLO, ANTLR or other parser grammar, for parsing QUERY EXPRESSION

  - by Jay Allard

  Greetings I'm working on a project that requires me to write queries in text form, then convert them to some easily processed nodes to be processed by some abiguous repository. Of everything there, the part I'm least interested is the part that converts the text to nodes. I'm hoping it's already done somewhere. Because I'm making stuff up as I go, I chose to use a LINQish expression syntax. from m in Movie select m.A, m.B I started parsing it manually and got the basics, but it's pretty cheesy. I'm looking for the better solution. I made some progress using MGrammar, but it would be nice if such a thing already existed. Does anyone know of anything that already does this? I looked for existing ANTLR templates, but no luck. Thanks for the help.

• How does Linq-to-Xml convert objects to strings?

  - by Eamon Nerbonne

  Linq-to-Xml contains lots of methods that allow you to add arbitrary objects to an xml tree. These objects are converted to strings by some means, but I can't seem to find the specification of how this occurs. The conversion I'm referring to is mentioned (but not specified) in MSDN. I happen to need this for javascript interop, but that doesn't much matter to the question. Linq to Xml isn't just calling .ToString(). Firstly, it'll accept null elements, and secondly, it's doing things no .ToString() implementation does: For example: new XElement("elem",true).ToString() == "<elem>true</elem>" //but... true.ToString() == "True" //IIRC, this is culture invariant, but in any case... true.ToString(CultureInfo.InvariantCulture) == "True" Other basic data types are similarly specially treated. So, does anybody know what it's doing and where that's described?

• SVM in OpenCV: Visual Studio 2008 reported error wrongly (or is it right?)

  - by Risa

  I'm using MS Visual Studio 2008, OpenCV, C++ and SVM for a OCR-related project. At least I can run the code until yesterday, when I open the project to continue working, VS reported this error: error C2664: 'bool CvSVM::train(const CvMat *,const CvMat *,const CvMat *,const CvMat *,CvSVMParams)' : cannot convert parameter 1 from 'cv::Mat' to 'const CvMat *' It didn't happen before and I haven't changed any code relating to it (I only changed the parameters for the kernel). The code got error is: Mat curTrainData, curTrainLabel; CvSVM svm; . . . svm.train(curTrainData, curTrainLabel, Mat(), Mat(), params); If I hover on the code, I still got this tip: image. Which means my syntax isn't wrong. So why do VS bother to report such an error?

• Perl: implementing a dispatch table in an OO module?

  - by Iain

  I want to put some subs that are within an OO package into an array - also within the package - to use as a dispatch table. Something like this package Blah::Blah; use fields 'tests'; sub new { my($class )= @_; my $self = fields::new($class); $self->{'tests'} = [ $self->_sub1 ,$self->_sub2 ]; return $self; } _sub1 { ... }; _sub2 { ... }; I'm not entirely sure on the syntax for this? $self->{'tests'} = [ $self->_sub1 ,$self->_sub2 ]; or $self->{'tests'} = [ \&{$self->_sub1} ,\&{$self->_sub2} ]; or $self->{'tests'} = [ \&{_sub1} ,\&{_sub2} ]; I don't seem to be able to get this to work within an OO package, whereas it's quite straightforward in a procedural fashion, and I haven't found any examples for OO. Any help is much appreciated, Iain

• Select on multiple criteria with XPath

  - by Matt Thrower

  I have an XML document which looks something like this: <meadinkent> <record> <comp_div>MENSWEAR</comp_div> <sty_ret_type>ACCESSORIES</sty_ret_type> <sty_pdt_type>BELTS</sty_pdt_type> <pdt_category>AWESOME_BELTS</pdt_category> </record> <medinkent> I want to useXPath to select nodes which match all four elements and I'm having trouble getting the boolean syntax right. I'm trying this to match the first two just as a test: "/meadinkent/record/comp_div[.='" & comp_div & "'] and /meadinkent/record/sty_ret_type[.='" & sty_ret_type & "']" Which is failing, saying no nodes are returned. Obviously I'm being very stupid - what am I doing wrong? Cheers, mAtt

• Wpf: Tips for better performance

  - by viky

  I am working on a wpf application. In which I am working with a TreeView, each node represents different datatypes, these datatypes are having properties defined and using data template to show their properties. My application reads from xml and create tree accordingly. My problem is that when I load it, it is too slow, I want to know about the tricks that will help me to improve performance of my(any) wpf application. Edit: Please provide me some tips for better performance in wpf!! I am using wpf Profiler but it is not much helpful for me.

• Flex: Get an item from a AdvancedDataGrid given an index

  - by David Wolever

  I've got a subclass of AdvancedDataGrid showing a tree-like data structure. How can I, given the index returned by calculateDropIndex, get the item at that index? After reading through reams of code, it seems like the least terrible way is: var oldSelectedIndex:int = this.selectedIndex; var mouseOverIndex:int = this.calculateDropIndex(event); this.selectedItem = mouseOverIndex; var item:* = this.selectedItem; this.selectedIndex = oldSelectedIndex; The other option seems to be tinkering around with the iterator property... But, judging by the way I've seen it used, that will get pretty harry pretty quickly too. So, how can I get the item at a particular index in an advanced datagrid without going insane?

• Overriding a function in Emacs Lisp

  - by scrapdog

  I would like to temporarily override the kill-new function. I have a way I want to reimplement kill-new that works in only in certain contexts, but I don't want to reimplement a special version of kill-region on top of that. (kill-new is called from kill-region) Since Emacs Lisp uses dynamic scoping, this should be possible, right? (On the other hand, it seems that this would be an unsafe thing to support, and it might make me a bit nervous knowing that it is possible...) I have experimented with using let and fset, but so far have found no way to get it to work as expected. So, hopefully someone can fill in the blank in the following pseudocode: (defun my-kill-new (string &optional replace yank-handler) (message "in my-kill-new!")) (defun foo () (some-form-that-binds-a-function (kill-new my-kill-new) (kill-region (point) (mark)))) What should some-form-that-binds-a-function be? Or am I barking up the wrong tree?

• 'Design By Contract' in C#

  - by IAmCodeMonkey

  I wanted to try a little design by contract in my latest C# application and wanted to have syntax akin to: public string Foo() { set { Assert.IsNotNull(value); Assert.IsTrue(value.Contains("bar")); _foo = value; } } I know I can get static methods like this from a unit test framework, but I wanted to know if something like this was already built-in to the language or if there was already some kind of framework floating around. I can write my own Assert functions, just don't want to reinvent the wheel.

• Finding the FORM that an element belongs to in JavaScript

  - by Magnus Smith

  How can I find out which FORM an HTML element is contained within, using a simple/small bit of JavaScript? In the example below, if I have already got hold of the SPAN called 'message', how can I easily get to the FORM element? <form name="whatever"> <div> <span id="message"></span> </div> </form> The SPAN might be nested within other tables or DIVs, but it seems too long-winded to iterate around .parentElement and work my way up the tree. Is there a simpler and shorter way? If it wasn't a SPAN, but an INPUT element, would that be easier? Do they have a property which points back to the containing FORM? Google says no...

• Why does a module compile by itself but fail when used from elsewhere?

• Actionscript 3: foreach drawing object in movieclip

  - by Mathias

  Hey, I got a europe map designed in flash (1 movieclip, 1 frame, really simple), which contains the map as drawing objects directly inside the scene and in addition some specific countries as clickable buttons. So far it's working fine. What I need now is to make all the other drawing objects clickable without having to edit and script each object. I'm thinking about something like this (pseudo code): foreach(obj in MovieClip) { if(obj !typeof(Button)) { obj.addEventListener(MouseEvent.MOUSE_DOWN, genericClickListener); } } I just don't know the syntax how to achieve that. Could anybody give me a hint? Thanks, Mathias

• Mouse interaction in ListBoxItem children (WPF)

  - by absence

  I have a ListBox with an ItemTemplate that contains a control that interacts with the mouse. This interfers with the selection functionality of the ListBox, i.e. clicking a control does not select the item. This is because ListBoxItem sets the Handled property of the mouse event to true in OnMouseLeftButtonDown. I tried the following protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e) { base.OnMouseLeftButtonDown(e); e.Handled = false; } but the ListBoxItem “takes over” the mouse and prevents the control from doing its own interaction. Then I had another idea protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e) { base.OnMouseLeftButtonDown(e); ((ListBoxItem)VisualTreeHelper.GetParent(VisualTreeHelper.GetParent(VisualTreeHelper.GetParent(this)))).IsSelected = true; } which actually works, but feels more like an ugly kludge than an elegant solution. Are there any better solutions that don't rely on the exact contents of the visual tree?

• How do I allow inline images with data urls on .NET 4 without triggering request validation?

  - by Johan Driessen

  I'm using the jQuery jstree plugin (http://jstree.com) in a ASP.NET MVC 2 project on .NET 4 RC. It comes with some stylesheets with inline images with data urls, like this: .tree-checkbox ul { background-image:url(data:image/gif;base64,R0lGODlhAgACAIAAAB4dGf///yH5BAEAAAEALAAAAAACAAIAAAICRF4AOw==); } Now, the url for the background image contains a colon, which .NET 4 thinks is an unsafe character, so I get this error message: A potentially dangerous Request.Path value was detected from the client (:). According to the documentation, I am supposed to be able to prevent this by adding <pages validateRequest="false" /> to my Web.config, but that doesn't seem to help. I have tried adding it to the main Web.config for the application, as well as to a special Web.config in the /config folder, but to no avail. Is there any way to get .NET to allow this?

• jQuery parent of a parent

  - by Bloudermilk

  Hello, I am currently trying to find the parent of a parent of an element. I have a link being clicked that is in a <td>, and I'd like to get the <tr> object. Why wont "$(this).parent().parent()" work? What will? Thanks, Brendan Edit: It appears an error in my syntax was throwing the whole thing off. "$(this).parent().parent()" does in fact work, but I wound up going with $(this).closest('tr')" because it seems like the most efficient solution.

• Strange PHP reference bug

  Hello, I have a really strange bug with my PHP code. I have a recursive code which build up a menu tree with object and one of my customers server can't make it work. Contructor: function Menu(&$menus, &$keys , &$parent, &$menu){ ... if($keys === NULL){ $keys = array_keys($menus); } ... for($x = 0; $x < count($keys); $x++) { var_dump($keys); $menu = $menus[$keys[$x]]; var_dump($keys); if($this->id == $menu->pid){ $keys[$x] = NULL; $this->submenus[] = new Menu($menus, $keys, $this, $menu); } } First var_dump give me back the array, the second give back the first element of $menus.

• Sharepoint - Navigation.QuickLaunch has missing items

  - by linqmonkey

  The following code generates an ASCII art tree view of a sharepoint site structure based on the items in the quick launch menu. But some are missing. From googling i've found suggestions that this may be because QuickLaunch only contains items that have been customised. Any idea how to fix this? I want to use the QuickLaunch items as many of the sites have subsites and pages that need to be displayed in a specific order. RecurseNavigation(SPWeb web) { depth++; foreach (SPNavigationNode node in web.Navigation.QuickLaunch) { Console.Write(new String('-', depth)); Console.WriteLine(node.Title + " ("+node.Url+")"); RecurseNavigation(root.OpenWeb(node.Url)); } depth--; }

• Implementing Brainf*ck loops in an interpreter

  - by sub

  I want to build a Brainf*ck (Damn that name) interpreter in my freshly created programming language to prove it's turing-completeness. Now, everything is clear so far (<+-,.) - except one thing: The loops ([]). I assume that you know the (extremely hard) BF syntax from here on: How do I implement the BF loops in my interpreter? How could the pseudocode look like? What should I do when the interpreter reaches a loop beginning ([) or a loop end (])? Checking if the loop should continue or stop is not the problem (current cell==0), but: When and where do I have to check? How to know where the loop beginning is located? How to handle nested loops? As loops can be nested I suppose that I can't just use a variable containing the starting position of the current loop. I've seen very small BF interpreters implemented in various languages, I wonder how they managed to get the loops working but can't figure it out.
