  • Converting button events etc to ASP.NET MVC

    - by Sophie88
    Given an asp.net webform page which does something like asp.net <asp:textbox id="txtA" runat="server" /> <asp:textbox id="txtB" runat="server" /> <asp:button id="btnAddTogether" runat="server" text="Go" onclick="btn_Click"/> <asp:textbox id="txtResult" runat="server" /> code behind protected void btn_Click(...) { txtResult.Text = txtA.Text + txtB.Text; } How would I convert this to ASP.NET MVC. It's a pretty trivial example, but I'm not sure about how to change my way of thinking.

  • Embarassing C++ question regarding const

    - by Neil Butterworth
    My comments on this answer got me thinking about the issues of constness and sorting. I played around a bit and reduced my issues to the fact that this code: #include <vector> int main() { std::vector <const int> v; } will not compile - you can't create a vector of const ints. I suppose I should have known this, but I've never needed to create such a thing before. However, it seems like a useful construct to me, and I wonder if there is any way round this problem - I want to add things to a vector (or whatever), but they should not be changed once added. There's probably some embarrassingly simple solution to this, but it's something I'd never considered before.

  • F# - Function with no arguments?

    - by Rubys
    When thinking in a functional mindset, given that functions are supposed to be pure, one can conclude any function with no arguments is basically just a value. However, reallity gets in the way, and with different inputs, I might not need a certain function, and if that function is computationally expensive, I'd like to not evaluate it if it's not needed. I found a workaround, using let func _ = ... and calling it with func 1 or whatever, but that feels very non-idiomatic and confusing to the reader. This boils down to one question: In F#, Is there a proper way to declare a function with zero arguments, without having it evaluated on declaration?

  • RabbitMQ as a proxy between a data store and a producer ?

    - by hyperboreean
    I have some code that produces lots of data that should be stored in the database. The problem is that the database can't keep with the data that it gets produced. So I am wondering whether some kind of queuing mechanism would help in this situation - I am thinking in particular at RabiitMQ and whether is feasible to have the data stored in its queues until some consumer gets the data out of it and pushes it to the database. Also, I am not particular interested whether that data made it to the database or not because pretty soon, the same data will be updated.

  • How do I create a no-javascript url hash handler for my website?

    - by Kenny Bones
    Ok, I'm not sure how this is normally done. But I've got a script that basically empties a div of content and then loads content from a div from a separate webpage, without reloading the current page. This works great. It's taken from this example actually, from net tuts (great site btw) http://nettuts.s3.amazonaws.com/011_jQuerySite/sample/index.html And the guy who wrote this even though about handling the url's since the url don't change when using his method. So he wrote a javascript snippet that looks up the url and loads the content accoringly. Which is not working btw. But I was thinking about people who don't have javascript enabled, or iPhone and iPad users ;) Copying URLs and sending to a friend won't work at all. So how is this typically done? And can it be done without javascript? Possibly by php?

  • Downloading game assests to SD card on Android

    - by hgpc
    I'm developing an Android game that has to download some assets to the SD card to keep the size of the app as small as possible. I was thinking of using an uncompressed zip file to bundle all the assets. A requirement from the client is to protect these assets as much as possible. Being part of the apk is considered enough protection, but if I do this the apk size will be enormous. If I just put a zip bundle in the SD card, then anyone can unzip it and explore its contents. Is there a simple way to do this without retorting to horrid DRM? Obviously if someone really wants to check the resources of an Android game, they can. I'm just looking for a simple solution to avoid making this very easy.

  • How to relate keywords to records - Many to Many

    - by webworm
    Hi All, I am looking for suggestions on database design for a sample jobs listing application. I have many jobs that I would like to associate various keywords with. Each job can have multiple keywords. I would like to store the keywords in a seperate table instead of in a field within the Job table so as to avoid mispellings in keywords. What is the best way to relate keywords to the jobs? I was thinking of using an intermediary table that would have a many to many relationship linking keywords to jobs. Is this the best way to go or should I just have a field in the Job table that contains multiple keywords? Thanks for any suggestions.

  • How to filter/sort/rank object model nodes?

    - by BCS
    I have some kind of object model and I need to filter and sort it's nodes for some kind of property. What kinds of automated systems exist to generate and select properties of the object model that correlate to what I want? (I'm intentionally being abstract and non-specific) I'm thinking of a system that works kind of like spam filters or supervised classification systems in that given an example data set it identifies rules that find nodes of interest. However I'm looking for a more general system in that it shouldn't require any design time information about the object model. It should work equality well as a spam filter on e-mail, a bug finder on a code base, an interest filter in a newsgroup or bot accounts finder on a social networking site. As long as it can explore the object model via reflection and be given a set of "interesting" nodes, it should be able to find rules that will find more nodes like them.

  • Set a session hash outside of RoR program?

    - by Sindri Guðmundsson
    Hi, I have had my new rails program up for a few days now. I'm running it on Ubuntu 10.4 with apache2 in another location than the website it's made for (it's a standalone database application for physiotherapists). The people I made it for now want me to deploy it to the public part of their website, only with one change. Those who open it via the link in the public-part should not be able to click one button! I was thinking of doing something like this in my view: <% if session[:inside]%> <%=button_to 'Sækja mælitæki', @link_to_mt%> <%end%> How could I set session[:inside] only to true if the program was started from within the private part of the webpage? I thought of creating two new actions, the other would set session[:inside] to true and the other to false, but that seems to me like a security risk, is it not? BR, Sindri

  • How to make a jquery lightbox open multiple images from one link?

    - by ritch0s
    Using a lightbox like ColorBox or jQuery Lightbox Plugin how can i make a single link which opens a gallery / array of images? For example i have 1 thumbnail and when a user clicks it i want it to open multiple pictures in the lightbox so the user can click next or previous to view all the pictures within that gallery. My thinking was that i just do it as normal 1 link to 1 picture then use jquery to hide all but the first link. There must be a better way? Thanks.

  • How to stop a MFC/win32 control re-painting

    - by John
    I have a CRichEditCtrl, and an algorithm works on its contents in-place, iterating through the contents and making changes. This seems to cause it to re-paaint every time, which causes flickering and a noticeable time to complete the operation, especially if the control starts scrolling. I wondered if there's a neat way for me to stop it repainting for a period. It's actually a custom subclass of CRichEditCtrl in use so I was thinking something like: void MyCustomEditCtrl::DoAlgorithm() { enableRepaint(false); ... //to the actual work ... enableRepaint(true); } What's the neatest approach? A custom on-paint handler which does nothing when an operation is in progress? Or can repainting actually be disabled?

  • PHP: "Footer function"?

    - by Ricket
    I have a project. It has a good number of PHP files. Each of these files includes a standard header. They don't include a standard footer. Now I want to do something just before the end of every page. I can go through each page and add the footer code, but I was wondering if there is an easier way (and I think I've seen something like it before, though I might be mistaken). Is there a way to set a "hook" or "trigger" function that will be executed at the end of a page, from the included header PHP script? I'm thinking of something like set_error_handler but to handle a page close event. Or like C's atexit function.

  • Returning an array from an activity

    - by Boardy
    I am currently working on an android project and I want to be able to startActivityForResult so that I can return an array of. The array is an ArrayList<Spanned> lets say its called myArray. From what I've read I can't return an array directly from the activty using the set result so I was thinking that once the array has added all the data to the array, I can then call the toString function on it, i.e. myArray.toString(). If I do this, I have no idea how I can then convert this back into the original ArrayList<Spanned>. Thanks for any help you can provide.

  • EntityFramework 4.0: can you return different types depending on data in the database?

    - by user200341
    I have a Media table in the database. I also have an IMedia interface. I have two different media types that implements the same interface: 1) AudioMedia 2) PictureMedia What I wonder here, is if I can use EntityFramework (I'm using an EDMX file but I have my models in a separate library, with automatic code generation turned off), and depending on the data in the database, select what type to get (AutioMedia or PictureMedia). Since they are both implementing the same interface (could be changed to an abstract class if needed I suppose), I'm thinking that somewhere along the way you could specify what class it should be. I should perhaps point out that I have a class that inherits from ObjectContext to access the objects. Perhaps there is something that that can be done?

  • In what package should a "Settings" class be placed?

    - by Tom
    I'm in the middle of building an application but found myself too easily creating new packages without keeping the project's structure in mind. Now, I'm trying to redo the whole project structure on paper first. I am using a Settings class with public properties, accessed as settings for several other classes around the project. Now, since this Settings class applies for the whole project, I am unsure if it should be packaged and if so, in what kind of package should it exist? Or should it be in the root (the default package) with the main application class? I've been thinking about putting it in my utils package, then again I don't think it really is an utlity. Any strategies on how to decide on such package structure for example for a Settings class?

  • rails eval code

    - by xpepermint
    Hey. I have to do a coll inside my model like this: import = Import.find(id) status = User.find(import.user_id).{XXX}.import(import.file.path) Notice a {XXX} which should be replaced by a dinamic variable of a submodel. Model User has_many groups, clients and products. In translation this would be status = User.find(import.user_id).groups.import(import.file.path) status = User.find(import.user_id).clients.import(import.file.path) status = User.find(import.user_id).products.import(import.file.path) I was thinking of import = Import.find(id) status = eval("User.find(#{import.user_id}).#{import.model}").import(import.file.path) but this gives me an error 'TypeError: can't convert nil into String'. Please tell me how would you fix that. Thx!

  • Layers with GDI+

    - by user146780
    I'm thinking of creating a drawing program with layers, and using GDI+ to display them. I want to use GDI+ because it supports transparency. The thing is, drawing lines to the DC is very fast, but drawing directly to a bitmap is very slow. It is only fast if you lock the bits and start setting pixels. Can I draw to multiple DC's in my WM_PAINT event, then just do DrawBitmap for each layer to the MemDC? What's the best way of going about this? Thanks

  • Call other activities in an activity?

    - by Mohit Deshpande
    Say I have 2 activities (ActivityOne and ActivityTwo). How would I call ActivityTwo from ActivityOne? Then how would I return to ActivityOne from ActivityTwo? For example, I have a listview with all the contacts on the host phone. When I tap on a contact, another activity shows information and allows editing of that contact. Then I could hit the back button, and I would go back to the exact state that ActivityOne was in before I called ActivityTwo. I was thinking an Intent object, but I am not sure. Could someone post some code?

  • Scraping with multiple IP, in java.

    - by Titi Wangsa bin Damhore
    Well basically I have a scraping application. It scrapes around n items per minute. currently i have only one IP. The site i'm scraping allows me 3 connections per IP. I'm thinking about getting another IP. so i'll be able to get 6 connections. in theory i should be able to get n items in 40 seconds, more or less. currently i'm using java (commons-httpcore) to get the job done. I'm not sure if this is java question or an OS question. my machine has IP 1 and IP 2 how do i connect to, say, www.microsoft.com, using IP 1 and using IP2? how can i specify, which ip i want to use to do a connection?

  • Reverse Search Best Practices?

    - by edub
    I'm making an app that has a need for reverse searches. By this, I mean that users of the app will enter search parameters and save them; then, when any new objects get entered onto the system, if they match the existing search parameters that a user has saved, a notification will be sent, etc. I am having a hard time finding solutions for this type of problem. I am using Django and thinking of building the searches and pickling them using Q objects as outlined here: http://www.djangozen.com/blog/the-power-of-q The way I see it, when a new object is entered into the database, I will have to load every single saved query from the db and somehow run it against this one new object to see if it would match that search query... This doesn't seem ideal - has anyone tackled such a problem before?

  • Feed char array into stdin

    - by Brian Lindsey
    I am writing a parser for a mini scripting language. Some of my grammar rules require jumping to a different location in the file to obtain information. There doesn't seem to be a straightforward way to accomplish this. So, I was thinking about loading my data files into a char array array and parsing line by line. This will allow me to jump all over the array with ease. My question is, is it possible to feed char arrays (i.e. char *) into stdin, so I can easily invoke the yyparse() function as needed.

  • In Python what's the best way to emulate Perl's __END__?

    - by FM
    Am I correct in thinking that that Python doesn't have a direct equivalent for Perl's __END__? print "Perl...\n"; __END__ End of code. I can put anything I want here. One thought that occurred to me was to use a triple-quoted string. Is there a better way to achieve this in Python? print "Python..." """ End of code. I can put anything I want here. """

  • Is there a method I can override on a JavaScript object to control what is displayed by console.log?

    - by agnoster
    I'm thinking in particular of Chrome, though Firebug would be interesting to. I've tried toString() and valueOf(), but neither of those seem to be used. Interestingly, if I take a function it'll display the function definition - but then if I add a toString() method it will show null! var a = function(){}; console.log(a); // output: function (){} a.toString = function(){ return 'a'; }; console.log(a); // output: null a.valueOf = function(){ return 'v'; }; console.log(a); // output: null Any ideas?

  • Why use third-party vector libraries at all?

    - by Patrick Powns
    So I'm thinking of using the Eigen matrix library for a project I'm doing (2D space simulator). I just went ahead and profiled some code with Eigen::Vector2d, and with bare arrays. I noticed a 10x improvement in assigning values to elements in the array, and a 40x improvement in calculating the dot products. Here is my profiling if you want to check it out, basically it's ~4.065s against ~0.110s. Obviously bare arrays are much more efficient at dot products and assigning stuff. So why use the Eigen library (or any other library, Eigen just seemed the fastest)? Is it stability? Complicated maths that would be hard to code by yourself efficiently?

  • Access DB with SQL Server Front End

    - by uyuni99
    I have an old Access application that has a lot of code in forms and reports. The database is getting too large and I am thinking of moving the back end to SQL Server. My requirements are as follows: The DB needs to be multiuser and the users (3-5) will need to log in over the web I would prefer not to re-write the forms and reports in ASP or some other web front end. When I think about my choices, I see them as: Have an Access ADP front end and allows remote log-in to the server where it is stored. Not sure if it is possible for 2 users to simultaneously log in Distribute an ADP front end to the users, but I am not sure if it is possible to connect to a SQL Server back end over the internet, and the network traffic may be an issue. Any other solution? I appreciate all help. u
