  • foreach with an array of stdclass objects

    - by Jared Steffen
    So, what I want to do is quite simple in my mind. I have an array that consists solely of four objects. I want to create a loop that will echo an attribute of each object in the array. The only success I've had, however, is echoing every object and every property of the objects. I've never dealt with objects so this is probably the TRUE root of the problem. There's been a few revisions but the only thing I've really excelled at is creating error codes. Here is what I have: $categories = get_categories(array('child_of' => '8')); foreach ($categories as $cat) { echo $cat->name; };

  • Is there a way to cut and paste or clone CSS from one element to another using JQuery?

    - by Jared Christensen
    I have a situation where I'm wrapping an image with a span and I want to remove all the CSS from the image and apply it to the span. Is there a way to do this with JQuery? JQuery: $(img).wrap('<span />'); Style Sheet: img { border: 5px solid red; padding: 10px; … } I would like do to do this with out editing the HTML or CSS. For example adding a class to the image would not work very well in my situation. I need a way to truly remove the CSS from one element and place it on another.

  • improve my jquery validation plugin code

    - by Jared
    Hi All Just hoping soemone can help me to write better code than I can come up with on my own. I am using the jquery validation plugin. I have some fields that are mandatory ONLY if certain options are chosen. The below code works fine. But the thing is, is that that my list of 'OR's is much longer than I've put here. and it needs to be applied not just to 'directorsName' but a whole long list of inputs, selects etc. My question is.. how can I wrap up the code contained inside the RETURN? (so I dont have to keep repeating my 'OR's. I'm guessign I need a function but I'm unsure of the syntax) $("#myForm").validate({ rules: { directorsName : { required: function(element) { return ( $('#account_for').val() == "Joint" || $('#directors_number').val() == "2" || $('#directors_number').val() == "3" ); } } } }); Thanks in advance

  • Using groovy ws with enum types?

    - by Jared
    I'm trying to use groovy ws to call a webservice. One of the properties of the generated class is it's self a class with an enum type. Although the debug messages show that the com.test.FinalActionType is created at runtime when the WSDL is read I can't create an instance of it using code like proxy.create("com.test.FinalActionType") When I try and assign a string to my class uin place of an instance of FinalActionType groovy is not able to do the conversion. How can I get an instance of this class to use in a webservice call? I've pasted the important part of the WSDL below. <xsd:simpleType name="FinalActionType"> <xsd:restriction base="xsd:string"> <xsd:enumeration value="stop"/> <xsd:enumeration value="quit"/> <xsd:enumeration value="continue"/> <xsd:whiteSpace value="collapse"/> </xsd:restriction> </xsd:simpleType>

  • How to get ListView to grow to the size of content

    - by Jared
    So I have a fairly complex activity the parent being a linearlayout with a table with some basic info and buttons. Then a couple listviews that the user can add items to. So these listviews grow more and more as the user uses the app. The problem I'm running into is the Linearlayout is bigger then the resolution of the screen and so it needs to scroll. So the scrolling doesn't work on the Listviews. I've tried playing with changing the layout_height of the listview and its child element with no success. Is there a way to make these couple listviews expand out to the amount of children? Or am I going about this all wrong? If so what other controls can I use? I'm open to any ideas. I really just don't know how to go about this. Thanks

  • Detecting coincident subset of two coincident line segments

    - by Jared Updike
    This question is related to: How do I determine the intersection point of two lines in GDI+? (great explanation of algebra but no code) How do you detect where two line segments intersect? (accepted answer doesn't actually work) But note that an interesting sub-problem is completely glossed over in most solutions which just return null for the coincident case even though there are three sub-cases: coincident but do not overlap touching just points and coincident overlap/coincident line sub-segment For example we could design a C# function like this: public static PointF[] Intersection(PointF a1, PointF a2, PointF b1, PointF b2) where (a1,a2) is one line segment and (b1,b2) is another. This function would need to cover all the weird cases that most implementations or explanations gloss over. In order to account for the weirdness of coincident lines, the function could return an array of PointF's: zero result points (or null) if the lines are parallel or do not intersect (infinite lines intersect but line segments are disjoint, or lines are parallel) one result point (containing the intersection location) if they do intersect or if they are coincident at one point two result points (for the overlapping part of the line segments) if the two lines are coincident

  • Why wont extern link to a static variable?

    - by Jared P
    Why does extern int n not compile when n is declared (in a different file) static int n, but works when declared int n? (Both of these declarations were at file scope.) Basically, why is int n in file scope not the same as static int n in the same scope? Is it only in relation to extern? If so, what about extern am I missing?

  • Why isn't our c# graphics code working any more?

    - by Jared
    Here's the situation: We have some generic graphics code that we use for one of our projects. After doing some clean-up of the code, it seems like something isn't working anymore (The graphics output looks completely wrong). I ran a diff against the last version of the code that gave the correct output, and it looks like we changed one of our functions as follows: static public Rectangle FitRectangleOld(Rectangle rect, Size targetSize) { if (rect.Width <= 0 || rect.Height <= 0) { rect.Width = targetSize.Width; rect.Height = targetSize.Height; } else if (targetSize.Width * rect.Height > rect.Width * targetSize.Height) { rect.Width = rect.Width * targetSize.Height / rect.Height; rect.Height = targetSize.Height; } else { rect.Height = rect.Height * targetSize.Width / rect.Width; rect.Width = targetSize.Width; } return rect; } to static public Rectangle FitRectangle(Rectangle rect, Size targetSize) { if (rect.Width <= 0 || rect.Height <= 0) { rect.Width = targetSize.Width; rect.Height = targetSize.Height; } else if (targetSize.Width * rect.Height > rect.Width * targetSize.Height) { rect.Width *= targetSize.Height / rect.Height; rect.Height = targetSize.Height; } else { rect.Height *= targetSize.Width / rect.Width; rect.Width = targetSize.Width; } return rect; } All of our unit tests are all passing, and nothing in the code has changed except for some syntactic shortcuts. But like I said, the output is wrong. We'll probably just revert back to the old code, but I'm curious if anyone has any idea what's going on here. Thanks.

  • Replacing div html() by echoing PHP - how to?

    - by Jared
    Hello, I have a multiple product elements that get their class and ID from PHP: $product1["codename"] = "product-1"; $product1["short"] = "Great Product 1"; $product2["codename"] = "product-2"; $product2["short"] = "Great Product 2"; <div class="leftMenuProductButton" id="'. $product1["codename"].'" >'. $product1["short"].'</div> <div class="leftMenuProductButton" id="'. $product2["codename"].'" >'. $product2["short"].'</div> These display as: <div class="leftMenuProductButton" id="product-1" > Great Product 1</div> <div class="leftMenuProductButton" id="product-2" > Great Product 2</div> In the page, I have an element that I want to replace the HTML: <div id="productPopupTop"> //Replace this content </div> Using jquery, I have tried the following: $( '.leftMenuProductButton' ).hover ( function () { var swapNAME = $(this).attr("id"); //gets the ID, #product-1, #product-2 etc. This works. $("#productPopupTop").html(' <? echo $' + swapNAME + '["short"] ?>'); //This is supposed to get something like <? echo $product-1["short"] ?> This doesn't appear to work. }, function () { //this is just here for later }); If I try to do an alert('<? echo $' + swapNAME + '["short"] ?>'); it will literally display something like <? echo $product-1["short"] ?> Please note that both the Javascript and the PHP are externally linked in a PHP file (index.php <<< (js.js, products.php) QUESTION: How do I replace the HTML() of #productPopupTop with the ["short"] of a product? If I should use Ajax, how would I code this?

  • How to iterate properly across a const set?

    - by Jared
    I'm working on a program that's supposed to represent a graph. My issue is in my printAdjacencyList function. Basically, I have a Graph ADT that has a member variable "nodes", which is a map of the nodes of that graph. Each Node has a set of Edge* to the edges it is connected to. I'm trying to iterate across each node in the graph and each edge of a node. void MyGraph::printAdjacencyList() { std::map<std::string, MyNode*>::iterator mit; std::set<MyEdge*>::iterator sit; for (mit = nodes.begin(); mit != nodes.end(); mit++ ) { std::cout << mit->first << ": {"; const std::set<MyEdge*> edges = mit->second->getEdges(); for (sit = edges.begin(); sit != edges.end(); sit++) { std::pair<MyNode*, MyNode*> edgeNodes = *sit->getEndpoints(); } } std::cout << " }" << std::endl; } getEdges is declared as: const std::set<MyEdge*>& getEdges() { return edges; }; and get Endpoints is declared as: const std::pair<MyNode*, MyNode*>& getEndpoints() { return nodes; }; The compiler error I'm getting is: MyGraph.cpp:63: error: request for member `getEndpoints' in `*(&sit)->std::_Rb_tree_const_iterator<_Tp>::operator-> [with _Tp = MyEdge*]()', which is of non-class type `MyEdge* const' MyGraph.cpp:63: warning: unused variable 'edgeNodes' I have figured out that this probably means I'm misusing const somewhere, but I can't figure out where for the life of me. Any information would be appreciated. Thanks!

  • Saving a grails object with a composite id

    - by Jared
    The answer to this may be obvious but how do you save an object, in grails, that has a composite id. I have an object that has a composite id including a long and a date and I am trying to save an instance of the object from the update method of another classes controller, and using (object).save() isn't working. Any tips or suggestions?

  • Is there any way to retrieve a float from a varargs function's parameters?

    - by Jared P
    If the function was defined with a prototype which explicitly stated the types of the parameters, eg. void somefunc(int arg1, float arg2); but is implemented as void somefunc(int arg1, ...) { ... } is it possible to use va_arg to retrieve a float? It's normally prevented from doing this because varargs functions have implicit type promotions, like float to double, so trying to retrieve an unpromoted type is unsupported, even though the function is being called with the unpromoted type do to the more specific function prototype. The reason for this is to retrieve arguments of different types at runtime, as part of an obj-c interpreter, where one function will be reused for all different types of methods. This would be best as architecture independent (so that if nothing else the same code works on simulator and on device), although if there is no way to do this then device specific fixes will be accepted.

  • How do I mount a remote Linux folder in Windows through SSH?

    - by Jared
    I'm a blind student currently in a system admin/shell programming class. Although ssh works fine for executing commands like ls, pwd, etc editors do not work well with my screen reader and an ssh session. I was wondering if it is possible to mount a Linux folder over ssh so it appears as a windows drive? This way I could edit any files I needed to with accessible software and not have to constantly use SCP to send files back and fourth.

  • How do I change the class of an object to a subclass of its current class in C++?

    - by Jared P
    I have an array of pointers to a base class, so that I can make those pointers point to (different) subclasses of the base class, but still interact with them. (really only a couple of methods which I made virtual and overloaded) I'm wondering if I can avoid using the pointers, and instead just make an array of the base class, but have some way to set the class to the subclass of my choosing. I know there must be something there specifying the class, as it needs to use that to look up the function pointer for virtual methods. By the way, the subclasses all have the same ivars and layout. Note: the design is actually based on using a template argument instead of a variable, due to performance increases, so really the abstract base class is just the interface for the subclasses, which are all the same except for their compiled code. Thanks

  • Are the atomic builtins provided by gcc actually translated into the example code, or is that just f

    - by Jared P
    So I was reading http://gcc.gnu.org/onlinedocs/gcc-4.1.0/gcc/Atomic-Builtins.html, and came across this: type __sync_and_and_fetch (type *ptr, type value, ...) type __sync_xor_and_fetch (type *ptr, type value, ...) type __sync_nand_and_fetch (type *ptr, type value, ...) These builtins perform the operation suggested by the name, and return the new value. That is, { *ptr op= value; return *ptr; } { *ptr = ~*ptr & value; return *ptr; } // nand Is this code literal? or is it just to explain what gcc is doing atomically using c-like syntax? And if this is the direct translation, can someone explain how it is atomic?

  • local file access with javascript

    - by Jared
    is there any local file manipulation that's been done with javascript? i'm looking for a solution that can be accomplished with no install footprint like requiring AIR. specifically, i'd like to read the contents from a file and write those contents to another file. at this point i'm not worried about gaining permissions, just assuming i already have full permissions to these files.

  • C (or C++?) Syntax: STRUCTTYPE varname = {0};

    - by Jared Updike
    Normally one would declare/allocate a struct on the stack with?: STRUCTTYPE varname; What does this syntax mean in C (or is this C++ only, or perhaps specific to VC++)? STRUCTTYPE varname = {0}; where STRUCTTYPE is the name of a stuct type, like RECT or something. This code compiles and it seems to just zero out all the bytes of the struct but I'd like to know for sure if anyone has a reference. Also, is there a name for this construct?

  • jQuery - Using .one() with hover

    - by Jared
    Is there any way to get a hover function to only execute once? This is what I'm currently trying: $('#ask').live('hover', function() { $('#homesearch-after').hide(300); $.doTimeout( 300, function() { hideClosedSearchLink(); showHomeSearch(); }); }); But that's not working. How can I only get this hover to activate once? I've tried changing .live with .one and .bind... resulting in nothingness.

  • How do I use Ajax and Jquery to get an array from PHP and post it?

    - by Jared
    Hello, I am using a separate PHP file as a configuration file for everything else on a basic ecommerce site. $product1["short"] = "product one"; $product1["menuimgslideshowsrc"] = "image/product1.jpg"; When I hover over a button, I want to get $product1["menuimgslideshowsrc"] and swap it out with an IMG SRC. I can do the swapping no problem, I need to know how to get the information stored in $product1["menuimgslideshowsrc"]. I assume I would use Ajax, but I am open to other ideas. Thanks in advance.

  • Apache's AuthDigestDomain and Rails Distributed Asset Hosts

    - by Jared
    I've got a server I'm in the process of setting up and I'm running into an Apache configuration problem that I can not get around. I've got Apache 2.2 and Passenger serving a Rails app with distributed asset hosting. This is the feature of Rails that lets you serve your static assets from assets0.example.com, assets1, assets2, and so on. The site needs to be passworded until launch. I've set up HTTP authentication on the site using Apache's mod_auth_digest. In my configuration I'm attempting to use the AuthDigestDomain directive to allow access to each of the asset URLs. The problem is, it doesn't seem to be working. I get the initial prompt for the password when I load the page, but then the first time it loads an asset from one of the asset URLs, I get prompted a 2nd, 3rd, or 4th time. In some browsers, I get prompted for every single resource on the page. I'm hoping that this is only a problem of how I'm specifying my directives and not a limitation of authorization in Apache itself. See the edited auth section below: <Location /> AuthType Digest AuthName "Restricted Site" AuthUserFile /etc/httpd/passwd/passwords AuthGroupFile /dev/null AuthDigestDomain / http://assets0.example.com/ http://assets1.example.com/ http://assets2.example.com/ http://assets3.example.com/ require valid-user order deny,allow allow from all </Location>
