• How to add http headers in suds 0.3.6?

  - by Esabe

  Hi everyone, I have an application in python 2.5 which sends data through suds 0.3.6. The problem is that the data contains non-ascii characters, so I need the following header to exist in the soap message: Content-Type="text/html; charset="utf-8" and the header that exists in the SOAP message is just: Content-Type="text/html" I know that it is fixed in suds 0.4, but it requires Python2.6 and I NEED Python2.5 because I use CentOS and it needs that version. So the question is: How could I change or add new HTTP headers to a SOAP message?

• Inheritance vs specific types in Financial Modelling for cashflows

  - by BlueTrin

  Hello, I have to program some financial applications where I have to represent a schedule of flows. The flows can be of 3 types: - fee flow (just a lump payment at some date) - floating rate flow (the flow is dependant of an interest rate to be determined at a later date) - fixed rate flow (the flow is dependant of an interest rate determined when the deal is done) I need to keep the whole information and I need to represent a schedule of these flows. Originally I wanted to use inheritance and create three classes FeeFlow, FloatingFlow, FixedFlow all inheriting from ICashFlow and implement some method GetFlowType() returning an enum then I could dynamic_cast the object to the correct type. That would allow me to have only one vector to represent my schedule. What do you think of this design, should I rather use three vectors vector, vector and vector to avoid the dynamic casts ?

• Overloading Controller Actions

  - by DaveDev

  Hi Guys I was a bit surprised a few minutes ago when I tried to overload an Action in one of my Controllers I had public ActionResult Get() { return PartialView(/*return all things*/); } I added public ActionResult Get(int id) { return PartialView(/*return 1 thing*/); } .... and all of a sudden neither were working I fixed the issue by making 'id' nullable and getting rid of the other two methods public ActionResult Get(int? id) { if (id.HasValue) return PartialView(/*return 1 thing*/); else return PartialView(/*return everything*/); } and it worked, but my code just got a little bit ugly! Any comments or suggestions? Do I have to live with this blemish on my Controllers? Thanks Dave

• boost::enable_if class template method

  - by aaa

  I got class with template methods that looks at this: struct undefined {}; template<typename T> struct is_undefined : mpl::false_ {}; template<> struct is_undefined<undefined> : mpl::true_ {}; template<class C> struct foo { template<class F, class V> typename boost::disable_if<is_undefined<C> >::type apply(const F &f, const V &variables) { } template<class F, class V> typename boost::enable_if<is_undefined<C> >::type apply(const F &f, const V &variables) { } }; apparently, both templates are instantiated, resulting in compile time error. is instantiation of template methods different from instantiation of free functions? I have fixed this differently, but I would like to know what is up. Thank you

• How to partition a plane

  - by puls200

  Let's say I have a fixed number (X) of points, e.g. coordinates within a given plane (I think you can call it a 2-D point cloud). These points should be partitioned into Y polygons where Y < X. The polygons should not overlap. It would be wonderful if the polygons were konvex (like a Voronoi diagram). Imagine it like locations forming countries. For example, I have 12 points and want to create 3 polygons with 4 points each. I thought about creating a grid which covers the points. Then iterate across the points, assigning them to the closest grid cells. Maybe I miss the obvious? I am sure there are better solutions. Thanks, Daniel I just found an optimization (kmeans++) .Maybe this will yield better results..

• Posting to tumblr in PHP

  - by Sherif

  I am trying to make a test post to my tumblr blog with a php script (that will eventually be ran as a cron job) I have been browsing google and read many answers on here and the closest I found is explained in this post: Tumblr OAuth using PHP's OAuth class I am using the code in his tutorial here: http://vigrond.com/blog/2012/02/04/oauth-extension-php-and-the-tumblr-api/ Pretty much as is, replacing the blogurl with mine and of course the consumer and secret key. When I run the .php script via my browser however, nothing happens. Any ideas? EDIT: The only error I found in cPanel's error log is this: [Wed Oct 31 00:29:25 2012] [error] [client xx.xx.xx.xx ] PHP Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /path on line 14 But I fixed this and the error does not appear anymore.

• mobile device - different background - media query not working

  - by AMC

  Live site. This is my first attempt at utilizing a different CSS for mobile devices vs. regular screens. To do this, I'm using- @media only screen and (min-device-width : 320px) and (max-device-width : 480px) { background: url('img/background.jpg') no-repeat center center fixed; background-size: cover; height: 100%; } However, it doesn't seem to be working (I can only test on iPhones). Any ideas as to why that may be? I've also tried @media all to no avail.

• Vim and clang_complete, how to explicitly compile my code

  - by puller

  I use Vim with clang_complete for omnicompletion. The plugin is automatically triggered when I need completion, e.g., after I type . or -> to access an object members or methods (see attached screenshot). The plugin works really nice, however I would need a way to trigger it manually (i.e. to compile my code for syntax checking). This is useful for two reasons: Static syntax checking Clear previous errors which have been fixed (which otherwise will remain in their buffer). See the two screenshots below for a better understanding. Any help is appreciated. Thanks. Screenshot 1 Screenshot 2

• Drag and drop objects onto a DIV.. relative vs absolute position and size of target DIV

  - by Scott

  Hi, I have a question about drag and drop and hoping one of you already solved it. I have an online web app where I can drag and drop annotations (arrows, stars) on top of an image that sits on a DIV. Here's some things to know. 1) The image can be any size (sometimes big sometimes small) 2) The DIV of wrapper can be left aligned or centered 3) The DIV of wrapper can be fixed or auto So is there any possible solution to make it so positions of annotations are always relative to the top left corner of the image? So I am using jQuery. How would I get an annotation's position always relative to the top left corner of an image once I drop object? Thanks!

• Navigation properties not set when using ADO.NET Mocking Context Generator

  - by olenak

  I am using ADO.NET Mocking Context Generator plugin for my Entity Framework model. I have not started on using mocks yet, just trying to fix generated entity and context classes to make application run as before without exceptions. I've already fixed T4 template to support SaveChanges method. Now I've got another problem: when I try to access any navigation property it is set to null. All the primitive fields inherited from DB table are set and correct. So what I am doing is the following using (var context = MyContext()) { var order = context.Orders.Where(p => p.Id == 7); var product = order.Products; } in this case product is set to null. But that was not a case while using default code generator, it used to return real product object. Thanks ahead for any suggestions!

• How do I sort feeds returned from Google Reader?

  - by Ed Marty

  When I query Google Reader for the list of subscriptions for a user, it seems to be returned in a fixed order, no matter what the order is as shown at google.com/reader. (see http://www.google.com/reader/api/0/subscription/list for the list I'm talking about) Each subscription returns a 'sortid', which Google Reader uses when the user rearranges subscriptions, by sending back a concatenation of all sortids in the new order after rearranging is finished. However, that sortid never changes. So my question is this: How do I actually get the order the subscriptions are supposed to be in? I've been using http://code.google.com/p/pyrfeed/wiki/GoogleReaderAPI as a reference, but it is lacking in this department, and I haven't found anything anywhere else either.

• Print new line in the source-code with jQuery.

  - by Kucebe

  I have a simple function in jQuery that creates new elements in the DOM. the problem is in the html source code, it append every element in the same line, and it's very bad to read. function _loadNewElements(elements){ for(var i=0; i<elements.length; i++){ var fixedElement = $('<img />') var position = elements[i].position; var cssMap = { 'position': 'fixed', 'top': position.top + "px", 'left': position.left + "px" }; fixedElement.css(cssMap); fixedElement.addClass("fixedTag"); fixedElement.attr('alt', elements[i].text); fixedElement.attr('src', "elements/" + elements[i].id + ".png"); fixedElement.appendTo($('#board')); //i'd like to print something here like ("\n"); } } I tried document.write("\n") but in this context it doesn't work. Any solution?

• How to find image width and height dynamically and specify height, width attibutes if over certain d

  - by Wbdvlpr

  Hi, I display some data on my website and one of the data feed elements is an image. [title] => Product title [description] => some description [image] => www.some-domain.com/product-image/p12345.jpg I then display this image using <img alt="product" src="<?=$data['image']?>" /> Most of the images are 80x80, 120x100 or other less than 150 in width, which perfectly fit in the website template, but some of them are quite large such as 800x600 which distort the layout. I want a control on these types. I tried to set WIDTH="150", but as the width vary they dont look good. I was thinking If I could set a fixed width to images, say, larger than 250px then I can live with it for now. Any ideas how to achieve this? Thanks

• Anchors within the document and their position.

  - by Jose Vega

  On the following website, www.josecvega.com, I have a navigation bar with years that link to sections on that same page. Unfortunately it is not working they way I hoped, when the user selects a year it moves to the section of the page, but puts that section on the top of the page. I have a fixed div on the top of the page that covers the sections and prevents it from properly displaying. What can I do for this to work? It hard to explain my situation, but it can be seen by going to www.josecvega.com and clicking one of the years.

• Bookmarkabale ajax calls with MVC routing

  - by devzero

  I have a page with a menu that uses JQuery AJAX calls to populate the page with. To reflect any changes I update the URL with a #... instead of ?... or /... So an URL that originally reads : htpp://localhost/pages/index/id=1 would look like : http://localhost/#pages/index/id=1. If a user bookmarks this, and later comes back to the page, I wonder if it's possible to use the second URL in my route decoding, or if I have to load it blank, then use the same JS/Ajax to populate the page? In my mind it is problematic to use Ajax in these cases if a user copies the link and mails it to a friend with JavaScript disabled. edit#1: Fixed some spelling.

• Rails 3 beta 1 - Nested layouts - LocalJumpError

  - by Art Shayderov

  Hi Nested layouts do not work in Rails 3. After I hit this I tried Rails Guides Example on a blank project (both ruby 1.9.1 and 1.8.7). LocalJumpError no block given on line <%= yield :stylesheets %. If you remove this line you will get the same error on the next yield statement. Could someone fix(patch) this? It's probably just a matter of calling block_given? in the right place. That would be great. Thanks Added on 4/3: Rails 3 beta 2 released. Problem fixed.

• Right floated div within a liquid-width div. How do I get this to work?

  - by DavidR

  I have a div, within the div is a name in an <h4> tag (it's semantically correct with the layout) and a div with some values describing that <h4> value. I want the nested div to be on the right side, and the only way I can get this to work is a fixed-width container and float: right;. As you can guess, the object breaks when the value of the <h4> causes the nested div to overflow. I've tried min-width, but it ends up stretching to the maximum size of the div containing the container div.

• Java - Unknown characters passing as [a-zA-z0-9]*?

  - by Twodordan

  Hello, I'm no expert in regex but I need to parse some input I have no control over, and make sure I filter away any strings that don't have A-z and/or 0-9. When I run this, Pattern p = Pattern.compile("^[a-zA-Z0-9]*$"); //fixed typo if(!p.matcher(gottenData).matches()) System.out.println(someData); //someData contains gottenData certain spaces + an unknown symbol somehow slip through the filter (gottenData is the red rectangle): In case you're wondering, it DOES also display Text, it's not all like that. For now, I don't mind the [?] as long as it also contains some string along with it. Please help. [EDIT] as far as I can tell from the (very large) input, the [?]'s are either white spaces either nothing at all; maybe there's some sort of encoding issue, also perhaps something to do with #text nodes (input is xml)

• CUDA & VS2010 problem

  - by Kristian D'Amato

  I have scoured the internets looking for an answer to this one, but couldn't find any. I've installed the CUDA 3.2 SDK (and, just now, CUDA 4.0 RC) and everything seems to work fine after long hours of fooling around with include directories, NSight, and all the rest. Well, except this one thing: it keeps highlighting the <<< >>> operator as a mistake. Only on VS2010--not on VS2008. On VS2010 I also get several warnings of the following sort: C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include\xdebug(109): warning C4251: 'std::_String_val<_Ty,_Alloc>::_Alval' : class 'std::_DebugHeapAllocator<_Ty>' needs to have dll-interface to be used by clients of class 'std::_String_val<_Ty,_Alloc>' Anyone know how this can be fixed?

• Create Outlines around line.

  - by Eric Muller

  Hi SO community! I am drawing graphs into a WinForms Picturebox. Now I am searching for a possibility to 'duplicate' a line (an array of points), so that the two resulting lines are positioned a fixed distance away from the original one. Like in this picture, I have the red line and want to get the black ones: I thought about just moving the line a few pixels up/right/up-right, but that leads to strange overlapping lines. Is there any other approach that does what I want? Any ideas would be greatly appreciated. Thanks!

• How to set variable size for List control item in Flex?

  - by joejax

  The following code display a list of comments using List control. The item height set to a fixed value (150), so it seems working: if the content is too long, the scrollbar shows... However, what I really want is not to set the height but let it to change according to the content size. Is there any way to accomplish this? <mx:List id="commentList" width="100%" dataProvider="{commentSet.commentArrayColl}" rowCount="{commentSet.commentArrayColl.length}" > <mx:itemRenderer> <mx:Component> <mx:VBox width="100%" height="150" > <mx:Text text="{data.commentContent}" /> <mx:Text text="{data.username} ({data.modified})"/> </mx:VBox> </mx:Component> </mx:itemRenderer> </mx:List>

• Conceptually, how does replay work in a game?

  - by SnOrfus

  I was kind of curious as to how replay might be implemented in a game. Initially, I thought that there would be just a command list of every player/ai action that was taken in the game, and it then 're-plays' the game and lets the engine render as usual. However, I have looked at replays in FPS/RTS games, and upon careful inspection even things like the particles and graphical/audible glitches are consistent (and those glitches are generally *in*consistent). So How does this happen. In fixed camera angle games I though it might just write every frame of the whole scene to a stream that gets stored and then just replays the stream back, but that doesn't seem like enough for games that allow you to pause and move the camera around. You'd have to store the locations of everything in the scene at all points in time (No?). So for things like particles, that's a lot of data to push which seems like a significant draw on the game's performance whilst playing.

• find a duplicate entry in an array in constant space and O(n) time [closed]

  - by Anubhav Agarwal

  Possible Duplicate: Algorithm to find a duplicate entry in constant space and O(n) time Given an array of N integer such that only one integer is repeated. Find the repeated integer in O(n) time and constant space. There is no range for the value of integers or the value of N For example given an array of 6 integers as 23 45 67 87 23 47. The answer is 23 (I hope this covers ambiguous and vague part) I searched on the net but was unable to find any such question in which range of integers was not fixed. Also here is an example that answers a similar question to mine but here he created a hash table with the highest integer value in C++.But the cpp does not allow such to create an array with 2^64 element(on a 64-bit computer).

• multi row header on Google Visualizations

The years headers can be fixed as I don't want to do sorting by that. Is there a way to do that in Google Visualizations? Update Attaching it with JS does NOT work, and it will disappear when sorting is done. $(".google-visualization-table-table").prepend("<tr class='google-visualization-table-tr-head'><td colspan='4'>something</tr>");

• What wiki tools exist to generate shippable user doc from a wiki?

  - by tletnes

  I am looking into using a wiki (prefer mediawiki, but not a req.) as the repository for developer generated documentation (User Guides, Release Notes, Application Notes, Errata, etc.) from a collaborative/easy-to-update point of view a wiki seems like a good match, however since this documentation will ultimately ship to customers we want to be able to export the documents in their final state (e.g. during the release cycle) to static versions that no longer include histories. Ideally the export would leave the document n a form where errors could be easily fixed by a non-programmer It would be good if niceties like section ordering and table of contents were available, or easy to add after the fact. Are any tools with features like these avalible?
