  • Member Function Pointer not quite right

    - by BlackDuck
    I have a SpecialisedRedBlackTree class that is templated. My Month class is not. In my Month class I have a private member which is an instance of SpecialisedRedBlackTree: SpecialisedRedBlackTree<Day> m_windSpeedTree; As you can see it will take the Day class/object (please correct me on any terms I get wrong). In my Month class, I have a method passing a method function pointer to this method: bool Month::CompareWindSpeed(Day a, Day b) { return ( a.GetData(WIND_SPEED_CODE) < b.GetData(WIND_SPEED_CODE)? true : false); } bool (Month::*myFuncPtr)(Day, Day); myFuncPtr = &Month::CompareWindSpeed; m_windSpeedTree.Insert(dayReading, myFuncPtr); But because I am passing a bool (Day, Day) pointer to a templated class expecting bool (T, T) T being part of this .... template Error 1 error C2664: 'SpecialisedRedBlackTree<T>::Insert' : cannot convert parameter 2 from 'bool (__thiscall Month::* )(Day,Day)' to 'bool (__cdecl *)(T,T)' Any advice?

  • C++ function object terminology functor, deltor, comparitor, etc..

    - by Robert S. Barnes
    Is there a commonly accepted terminology for various types for common functors? For instance I found myself naturally using comparitor for comparison functors like this: struct ciLessLibC : public std::binary_function<std::string, std::string, bool> { bool operator()(const std::string &lhs, const std::string &rhs) const { return strcasecmp(lhs.c_str(), rhs.c_str()) < 0 ? 1 : 0; } }; Or using the term deltor for something like this: struct DeleteAddrInfo { void operator()(const addr_map_t::value_type &pr) const { freeaddrinfo(pr.second); } }; If using these kinds of shorthand terms is common, it there some dictionary of them all someplace?

  • What are parts of a PHP function named?

    - by MikeG
    I am having trouble figuring out a problem and it is because I don't know the correct terms to be searching for. Could someone please name all the parts of a PHP function and if I'm missing something please add it. function my_function( non_variable $variable_one, $variable_two = "", $variable_three ) { /* inside stuff (Statement?) */ } The answer I'm looking for would look something like this function: declaration my_function: name non_variable: Please Answer $variable_one: variable filled with non_variable The one I really need to know about are non_variable and $variable_one, Thanks! EDIT: more detail about the function function my_function(custom_name $company) { $website = $company->company_website; /* Additional stuff */ }

  • Client validate non-model bound checkbox while using MVC 2 jQuery Validation

    - by Justin Saraceno
    Have: Using ASP.NET MVC 2, DataAnnotationsModel based server validation, and client validation with jQuery. Anything in my model is validated perfectly on the client with jQuery based validation (jQuery.validate and MicrosoftMvcJQueryValidation.js). Need: Adding an additional HTML <input type="checkbox" id="terms" /> to my form. I need jQuery validation to require that this checkbox is checked AND somehow hook it in with whatever jQuery client script MVC is automagically controlling. Yes, I know it won't validate on the server side, but I don't need or want it to. Seems like it should be simple but I'm new to MVC, a total beginner at jQuery, and my searches have been coming up blank. Any help would be appreciated!

  • The importance of knowing c++ for web application development

    - by neitony
    I'm a php developer and I want to broaden my knowledge base by learning a higher language (java, c#, c++). My specialty is in building web applications (ria etc). I'm trying to think of the appropriate path to take (hedging my bets so to speak) in terms of which language I should be focusing on. I love open source technology but at the same time C# seems to be getting a lot of notoriety. Despite the newer technologies available there still remains c++ which is the staple for many popular vendors including google and facebook (hip hop) in building scalable and robust cross platform apps. Can anyone offer suggestions as to how I should be looking at this. Should I go Java, C# or C++). They all take time to master and I just want to choose a specialty. Thanks

  • Sharepoint Server 2010 Layout change

    - by user260824
    hi, I have 2 questions about sharepoint 2010. When will Sharepoint Server 2010 realeased ? Is Sharepoint Server 2010 easy customized in terms of layout aspect ? Description:We have a goverment client. They care UI more than other aspects such as fucntionality. So this B/S project will have a very customizble UI, and the client is highly likely to modify the UI at any time. I have reviewed Sharepoint Server 2010 that it is easy to make different themes, but I am wondering if it is still easy to modify website's layout. Thank u.

  • Twitter OAuth question

    - by Squall
    Hi there, I'm making a Twitter client in Java, and I've came to a problem I don't know how to solve it. How the hell I store open auth for twitter? I mean it doesn't make very sense for a person to allow an application every time he wants to use the client. I've been look at the Twitter documentation, but I must say, it's really poor in terms of Java. So do you guy have some idea to solve this? Thanks in advance!

  • fastest method for minimum of two numbers

    - by user85030
    I was going through mit's opencourseware related to performance engineering. The quickest method (requiring least number of clock cycles) for finding the minimum of two numbers(say x and y) is stated as: min= y^((x^y) & -(x<y)) The output of the expression x < y can be 0 or 1 (assuming C is being used) which then changes to -0 or -1. I understand that xor can be used to swap two numbers. Questions: 1. How is -0 different from 0 and -1 in terms of binary? 2. How is that result used with the and operator to get the minimum? Thanks in advance.

  • JQuery: Selecting Text in an Element (akin to highlighting with your mouse)

    - by Jason
    I would like to have users click a link that then selects the html text in another element (NOT an input). By "select" I mean the same way you would select text by dragging your mouse over it. This has been a bear to research because everyone talks about "select" or "highlight" in other terms. Is this possible? My code so far is thus: html: <a href="javascript:" onclick="SelectText('xhtml-code')">Select Code</a> <code id="xhtml-code">Some Code here </code> js (jquery): function SelectText(element) { $("#" + element).select(); } but it doesn't work. Am I missing something blatantly obvious? Thanks

  • Is there a way to create my own "push pins" for a image without using Google Maps API?

    - by Charlie
    I am interested in working with friends via the internet on a fantasy world map. One of the things I want to do is host an image of the map online and allow us to insert push pins into the image that would then be associated with infoboxes. I don't want to resort to using the Google Map APIs mainly because this is something I want to just share among friends and not publicly. Terms of usage for the APIs state we would need to make the implementation available for everyone. This seems simple enough yet I've no idea how to do this. I looked into image maps, but that requires constant updates to the html markup itself. I just want to insert/delete/edit pushpins and infoboxes on the image and through our site itself. Can someone help me get started?

  • In few words, what can be said about Func<>

    - by Richard77
    Hello, I've been seing Func< for sometime now, and I've manage to avoid it (for now). But, now it looks like I can't dodge it forever. For instance, I tried Dynamic Linq, but almost everything was in terms of Func<. I've tried one of my book (C# 2008/Deitel&Deitel) and also MSDN but I'm not getting it yet. They all jump straight in the subject. What can be said (in few words) about Func< Can I get some links on the web that can get me started on that matter? Thanks for helping

  • Svn: how to remove all deleted files from repository ?

    - by Patrick
    I have a script in which I add all new files before to commit my working copy to my repository with this line: svn status | grep ^\? | awk '{print $2}' | xargs svn add I now want to add a line that delete from repository all deleted files in my working copy. In other terms, I cannot specify them one by one, and I need to detect them with svn status and then automatically remove them. However the line doesn't work. svn status | grep ^\! | awk '{print $2}' | xargs svn --force delete As you can see I've replaced "?" with "!" and "add" with "--force delete" Could you tell me why it doesn't work ? ps. I know it is a risky procedure. I've already discussed all about it. thanks thanks

  • How to handle huge table ?

    - by misha-moroshko
    I would like to display to user a table which contains ~500,000 rows. The table should be calculated based on a file (i.e. the table is known at the beginning, and does not change). I guess that building the HTML text of this table is not a good idea in terms of memory performance. So how can I build such table ? I would like user to be able to scroll the table using a vertical scroll bar. Is it possible to build on the fly only the visible part of the table ? I'm afraid to see delays because of this. Is it a better idea to use server side programming rather than Javascript ? Any advise would be appreciated.

  • How to test obtaining a list of files within a directory using RSpec?

    - by John Topley
    I'm pretty new to the world of RSpec. I'm writing a RubyGem that deals with a list of files within a specified directory and any sub-directories. Specifically, it will use Find.find and append the files to an Array for later output. I'd like to write a spec to test this behaviour but don't really know where to start in terms of faking a directory of files and stubbing Find.find etc. This is what little I have so far: it "should return a list of files within the specified directory" do end Any help much appreciated!

  • How do I add items to the Finder context menu in Mac OS X?

    - by mystro
    I'm in the process of porting a Windows application to OS X (we wrote it in Java so most of the code is portable), but what I'm currently unsure of is how to add context menu items in the Finder window when the user right clicks on an item (i.e. I wish to add some items to the the menu that has "Open" "Open with" , "Get Info", etc... when the user right clicks). Most of the articles I've found deal specifically with Windows (I've searched for "context menus" and "shell extension", but I believe I may be searching the wrong terms), so I'm curious as to how to go about adding this in Mac or what literature I should be reading.

  • Is there a transformation matrix that can scale the x and/or y axis logarithmically?

    - by Dave M
    I'm using .net WPF geometry classes to graph waveforms. I've been using the matrix transformations to convert from the screen coordinate space to my coordinate space for the waveform. Everything works great and it's really simple to keep track of my window and scaling, etc. I can even use the inverse transform to calculate the mouse position in terms of the coordinate space. I use the built in Scaling and Translation classes and then a custom matrix to do the y-axis flipping (there's not a prefab matrix for flipping). I want to be able to graph these waveforms on a log scale as well (either x axis or y axis or both), but I'm not sure if this is even possible to do with a matrix transformation. Does anyone know if this is possible, and if it is, what is the matrix?

  • Are these 2 sql queries equivalent in all respects (e.g. estimated and actual execution plan)?

    - by Xerion
    Are query 1) == 2) in terms of estimated query plan AND actual plan? (can statistics affect the actual plan here, ever?) declare @cat int -- input param from prc ... 1) select * from A as a join B as b on b.id = a.id on b.cat = @cat join C as c on c.fid = b.fid on c.cat = @cat where a.cat = @cat 2) select * from A as a join B as b on b.id = a.id on b.cat = a.cat join C as c on c.fid = b.fid on c.cat = b.cat where a.cat = @cat It seems to me that these should logically be equivalent and the execution plan should always be the same regardless of actual difference in tables. And adding more conditions either in join, or where, or add more tables to join shouldn't change this. Are there cases this is not true?

  • PHP-friendly NoSQL solutions

    - by mattbasta
    I'm looking to use a NoSQL solution for my next project, which will be written in PHP. What choices do I have in terms of NoSQL solutions that can easily interfaced via PHP? I haven't done much thinking about the architecture yet, so I'm not sure what my needs will be; I'd simply like to know what my choices are so I don't build something I can't reasonably implement. For instance, I know Cassandra has Pandra, but that's just a PHP library. MongoDB has a native PECL extension.

  • Any good class diagram editors out there for Java (not UML)

    - by user85116
    I'm looking for an editor that can create class diagrams, similar to the typical UML class diagram, but specifically for java (so using java terminology; instead of terms like "generalization, realization etc", we use the java equivalents "interface, abstract class, extends etc"). I've looked into UML several times, but each time I've been turned off by the shear amount of "stuff" that comes with UML. I just want to be able to model my java classes quickly and intuitively, without getting bogged down by all the cruft that comes with UML. Preferably, it would come with a source reader that can keep the diagram up to date, and with a few nice features like "show only public methods in this class" etc. As well, it would automatically "know" about the classes in the standard java library, and possibly even be able to read classes from jars. Performance is also a big thing for me, I don't like having to wait 2 seconds for a popup menu to appear, or watch the diagram jerk crazily while resizing an element in the model. What do you think, am I asking too much?

  • iPhone SDK: Downloading large files from a server into the app's documents.

    - by Jessica
    Hi, I am building an app that plays multiple video files, But I would like to know How do you download a video file (100mb - 300mb) from a server into the application's documents so it can later be locally referred to in code? The reason I want this type of a set up in my app is that I don't want the app binary to be made unnecessarily large due to including videos some users may not want. Also does this violate any of apple's terms? Also would it be simple to implement a progress view with this kind of set up and if so how? Any help is appreciated.

  • C++ - Efficient container for large amounts of searchable data?

    - by Francisco P.
    Hello, everybody! I am implementing a text-based version of Scrabble for a College project. My dictionary is quite large, weighing in at around 400.000 words (std::string). Searching for a valid word will suck, big time, in terms of efficiency if I go for a vector<string> ( O(n) ). Are there any good alternatives? Keep in mind, I'm enrolled in freshman year. Nothing TOO complex! Thanks for your time! Francisco

  • Language restrictions on iPhone lifted?

    - by John Smith
    Apparently Apple has changed some term in the agreement again. From http://www.appleoutsider.com/2010/06/10/hello-lua/ section 3.3.2 is now Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application. instead of the original No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). I am more interested in embedding Lua, but other people have other embeddings they want to make. I am wondering how you ask for permission, and what they mean by the terms "minor features" and "consistent" and how will Apple interpret this section? It seems to have enough loopholes to drive a real firetruck through.

  • Looking for a good course/book/resource on modern databases

    - by spanky
    This is slightly embarrassing. I'm a professional developer working at one of the big tech companies and I've never used a database. I've got an idea for a website I want to build as a learning experience and possibly as a business, but I don't have the faintest idea what database to use, let alone how to fix/debug the database when I run into problems. I'm looking for a course, a website, a book, etc., that will give me an overview of modern database technology (SQL vs. NOSQL vs. relational vs. non-relational (I only have a vague idea what these even mean)). I'm starting by googling/wikipediaing all of these terms, but if there are better, comprehensive resources available that I should be aware of, I'd love to hear about them.
