• How to plan mine web based project before starting code ?

  - by Arsheep

  Me and mine friend started working together as partners , we have decided to make Kick-as* website after website. We have the ideas written down like 100's of them (yes we are choosing best and easy among them first). Mine friend do the layout design and arranging things , and mine part is coding and server management. The little problem i am facing is lack of experience in planing a project .What i do is , i just start the code straight away and along with code I make DB , Like when i need a table i make it. I know this is very bad approach for a medium sized project. Here at stackoverflow i saw lots of experienced coders . Need to learn a lot from you guys :) . So can you plese help me on how to plan a project and what coding standard/structure/frameworks to be used (I do PHP code). Thanks in advance.

• Mysql transactions issue

  - by Stann

  In straight mysql script I'd do transactions like this: START TRANSACTION; SELECT @A:=SUM(salary) FROM table1 WHERE type=1; UPDATE table2 SET summary=@A WHERE type=1; COMMIT; i'm a little confused about how transactions work in PDO. It looks like there are beginTransaction() and commit() methods - so I'm not sure are these just convenience wrappers around staright SQL? or are they doing some more job behind the doors? In other words - are these examples below essentially the same? example 1: $dbh->exec( 'START TRANSACTION' ); //...do some db work here... $dbh->exec( "COMMIT" ); example 2: $dbh->beginTransaction(); //...do some db work here... $dbh->commit();

• ORMs and Constructors

  - by Harper Shelby

  I'm looking over .NET ORM implementations, and I have a major burning question - are there any .NET ORM implemenations that don't require public properties for every field in the database? When I see examples like this, a little bell goes off in my head. I firmly believe in encapsulation, and being forced to open the kimono of my objects just to make them work nicely with persistence frameworks gives me the heebie-jeebies. Is this sort of accessibility required in all ORMs out there? If not, please point me to examples of those that don't need it!

• Best solution for language documentation.

  - by Simone Margaritelli

  I'm developing a new object oriented scripting language and the project itself is quite ready for audience now, so i'm starting to think about a serious (not as "drafty" as it is right now) way of document its grammar, functions from standard library and standard library classes. I've looked a bit around and almost every language hash its own web application for the documentation, Python uses Sphinx for instance. Which is the best PHP (don't have the time/will to install mod_who_knows_what on my server) application to accomplish this? I've used mediawiki a bit but i found its tag system a little bit hard to use in this context. Thanks for your answers.

• C# animation - move object from A to B or by angle

  - by Nullstr1ng

  Hi am just doing a little animation which moves an object from point a to point b or by angle/radians. what I currently have is this Point CalcMove(Point pt, double angle, int speed) { Point ret = pt; ret.X = (int)(ret.X + speed * Math.Sin(DegToRad(angle))); ret.Y = (int)(ret.Y + speed * Math.Cos(DegToRad(angle))); return ret; } but it doesn't look what i expected. please help? update: oh and am using NETCF

• Is this class + constructor definition pattern overly redundant?

  - by Protector one

  I often come across a pattern similar to this: class Person { public string firstName, lastName; public Person(string firstName, string lastName) { this.firstName = firstName; this.lastName = lastName; } } This feels overly redundant (I imagine typing "firstName" once, instead of thrice could be enough…), but I can't think of a proper alternative. Any ideas? Maybe I just don't know about a certain design pattern I should be using here? Edit - I think I need to elaborate a little. I'm not asking how to make the example code "better", but rather, "shorter". In its current state, all member names appear 3 times (declaration, initialization, constructor arguments), and it feels rather redundant. So I'm wondering if there is a pattern (or semantic sugar) to get (roughly) the same behavior, but with less bloat. I apologize for being unclear initially.

• Ruby (on Rails) && PHP - two great things that work great together???

  - by pedalpete

  I've done very little work with Ruby, and have an app I've written in PHP. I would like to add some functionality which is available in open sourced Ruby code. I could either try to translate the Ruby to PHP, or try mixing the two. Though I think the mixing part would be somewhat silly. I believe my options are to either mix ruby with php, or translate the ruby code into php. Anybody have any suggestions on this, or other ideas? I am not really interested in converting my entire app into Ruby just so I can get this feature (I saw Derek Sivers post about that which convinced me. http://www.oreillynet.com/ruby/blog/2007/09/7%5Freasons%5Fi%5Fswitched%5Fback%5Fto%5Fp%5F1.html)

• Making a field unavailable to a user with javascript in MS CRM 4

  - by mwright

  I am trying to disable a field, i.e. grey it out and not allow the user to select it. To achieve this effect I am currently calling crmForm.all.new_attribute1.disabled = true; crmForm.all.new_attribute2.Disabled = true; The Disable, with a capital D, makes the field grayed out but the user can still put the cursor in that field or tab to it. The disable, with a little d, makes the field unavailable to the cursor and via tab, but gives no visual indication that it can't be interacted with. Is there a better way to do this, one call that will achieve similar results or am I stuck having both there?

• Why the macros in Objective-C / Cocoa?

  - by Joe

  I'm coming from a place without macros (Java/Python/C#/Scala) so perhaps my perspective is distorted but... Why are macros used in Cocoa? Two that spring to mind are NSLocalizedString and NSAssert (and STAssert). Would it be so hard / unsuitable to make them functions (which could be inlined)? I suppose I find them a little bizarre as an unnecessary throw-back to C (and yes, I am familiar with the pedigree of Obj-C). Is it just something that was done back in the day or is there a specific reason?

• does a switch idiom make sense in this case?

  - by the ungoverned

  I'm writing a parser/handler for a network protocol; the protocol is predefined and I am writing an adapter, in python. In the process of decoding the incoming messages, I've been considering using the idiom I've seen suggested elsewhere for "switch" in python: use a hash table whose keys are the field you want to match on (a string in this case) and whose values are callable expressions: self.switchTab = { 'N': self.handleN, 'M': self.handleM, ... } Where self.handleN, etc., are methods on the current class. The actual switch looks like this: self.switchTab[selector]() According to some profiling I've done with cProfile (and Python 2.5.2) this is actually a little bit faster than a chain of if..elif... statements. My question is, do folks think this is a reasonable choice? I can't imagine that re-framing this in terms of objects and polymorphism would be as fast, and I think the code looks reasonably clear to a reader.

• List replies in a winform

  - by andrew

  In my C# app I get an xml from a server that contains some replies like in a forum thread (with elements like author, time, body, title, whatever). When I get this xml, I create a new form in which i want to display these replies, and a little text box with an "add reply" button. I'd also like some edit buttons on perhaps my own replies in the reply list displayed in the form. The simplest way that came to my mind to display the replies is to put a web browser control in the form, generate a full html page in a string from the xml, and throw it in that web browser control. And under it i can put the text box with the add reply button. Everything is ok, except that i have no idea of how i could implement the edit function on my own replies (i mean i could add a link in there... but link to what) I would like to know if there is a way to get that edit event from the web browser control (my guess is i can't) or another (maybe simple/easy) idea of displaying the replies in a winform using other controls

• Emails, a different 'reply to' address then sender address.

  - by dcrodjer

  I have a contact form on a website (a general form: name, email, subject, message) in which mails are sent using google apps smtp to the admins. Currently if an administrator wants to reply to the mail directly selecting the reply option, the person's reply's To field will be filled by the sender's address automatically. What I wan't to ask is, Is there any standardized way to pass on some additional info with the mail which would define any reply to the mail should go to this address instead of the sender's? It does seems that there is a little chance for this option as it may lead to some problems due to spammers (They may define a custom reply field in their mail and a general user might not look where they are replying). So as an alternative what I thought is to find a way to create a filter with sender's account which figures out the reply email address from the format and forwards the mail (Doesn't seems like a good solution and I have no idea how to achieve this). I have tagged django, though this is not directly related with this, as I will finally implement this through django.

• core-plot and NSDate (iPhone)

  - by Urizen

  I wish to plot a line graph where the x-axis is defined as a number of days between two dates and the y-axis is a value that varies on each of the days. I can plot the y values as an NSNumber but I have no idea how to set the ranges and the markup on the x-axis. I have looked at the date example in the "examples" directory of the core-plot distribution but have found it a little confusing. Does anyone know of a tutorial, or code sample, which might asist me in this regard? Thank you in advance.

• Signal amplitude against time (java)

  - by wsr74ws84

  Hi everyone , I'm racking my brain in order to solve a knotty problem (at least for me) While playing an audio file (using java) I want the signal amplitude to be displayed against time. I mean I'd like to implement a small panel showing a sort of oscilloscope .(SPECTRUM ANALYZER) The audio signal should be viewed in the time domain (vertical axis is amplitude and the horizontal axis is time) Does anyone know how to do it? Is there a good tutorial I can rely on? Since I know vwry little about java , I wish someone could help me . Thanks in advance.

• Highlight polygon and tint rest of map using Google Maps

  - by Haes

  Hi, I'd like to display a highlighted polygon using Google Maps. The idea is that the polygon in question would be displayed normally and the rest of the map should be darkened a little bit. Here's an example image what I would like to accomplish with a polygon from Austria: Unfortunately, I'm a complete rookie when it comes to Google Maps API's and map stuff in general. So, is this even possible do this with Google Map API's? If yes, with what version (v2, v3)? Would it be easier to do it with other map toolkits, like openlayers? PS: One idea I had, was to build an inverse polygon (in this example, the whole world minus the shape of austria) and then display a black colored overlay with transparency using this inverted polygon. But that seems to be quite complicated to me.

• Subversion: setting up a remote repository and running my site off it?

  - by Matt Andrews

  Hi all. I'm new to SVN and have experimented with it locally on my Dreamhost test server (which has a Subversion "one-click-install" function). Having found my way around the functionality I'm definitely sold, but a little lost about using it to manage my work website (not hosted with Dreamhost, so not offering a one-click SVN installation). Am I correct in thinking that I can set up a repository on my website root (which contains all the files), and then when I develop new features and run a commit, this will update my site? Is this the proper workflow for this sort of thing? If so, is there a standard way to set this kind of thing up on my remote server? Thanks.

• Is *not* using the asp.net membership provider a bad idea?

  - by EJB

  Is it generally a really bad idea to not use the built-in asp.net membership provider? I've always rolled my own for my asp.net apps (public facing), and really have not had any problems in doing so. It works, and seems to avoid a layer of complexity. My needs are pretty basic: once setup, the user must use email address and password to login, if they forget it, it will be emailed back to them (a new one). After setup there is little that needs to be done to each user account, but I do need to store several extra fields with each user (full name, telephone and a few other fields etc). The number of users that required login credentials are small (usually just the administrator and a few backups), and everyone else uses the site unauthenticated. What are the big advantages that I might be missing out on by skipping the asp.net membership provider functionality?

• Adding dlls in VS 2008

  - by Bart

  Hello, i would like to add some external .dll libraries e.g. glut32.dll (but it's only example) in vs 2008 using C#. Can you please tell me what should i do step by step? i am a little bit confused cause i found a lot of solutions to add dll files but they significantly differ.. some of them add dll's only using code, some using properties in vs, add references and in other tutorials there is about registering dlls in system. But how to put it all together? Regards!

• Creating compound applications in Windows 7

  - by Mmarquee

  I need to port a suite of Windows applications (running under XP with little security turned on) to Windows 7 with various levels of security, depending on how our clients may configure it. Each functional area is a seperate executable or DLL that is downloaded and registered by a central 'compound' application. This means that the different parts are all joined together to form in effect a large single application. My problem is that the compound application knows about the other applications via COM registery, either as a typelibrary or as OCXs, where appropriate. I have tried several questions here to try and solve the problems I am getting, but I don't seem to be able to get around the problem of needing elevated access to register applications and access the registry. Our clients will be expecting the same (relatively) seemless download and activation process as current under XP. So does anyone have a solution for registering typelibraries and OCX controls without need to go through an elevation process. Thanks in advance

• Parsing and validating arbitrary date formats in ruby (on rails)

  - by Matt Briggs

  I have a requirement to handle custom date formats in an existing app. The idea is that the users have to do with multiple formats from outside sources they have very little control over. We will need to be able to take the format and both validate Dates against it, as well as parse strings specifically in that format. The other thing is that these can be completely arbitrary, like JA == January, FE == February, etc... to my understanding, chronic only handles parsing (and does it in a more magical way then I can use), and enter code here DateTime#strptime comes close, but doesn't really handle the whole two character month scenario, even with custom formatters. The 'nuclear' option is to write in custom support for edge cases like this, but I would prefer to use a library if something like this exists.

• asynchronous method executing

  - by alexeyndru

  I have a delegate method with the following tasks: get something from the internet (ex: some image from a web site); process that image in a certain way; display the result in a subview ; getting the image takes some time, depending on the network's speed so the result of its processing is displayed in the subview after that little while. my problem: during the time between getting the image and showing the result the device looks unresponsive. any attempt to put some spinner, or any other method which is called inside this main procedure has no effect until the result is processed. how should I change this behaviour? I would like to put a big spinner during that waiting time. thank you.

• Is there any framework for Windows Forms, DB driven application development/prototyping?

  - by dolzenko

  I'm writing simple database driven application, 80% of functionality is CRUD operations on about 15 tables. Coming from web development background I figured I can cover almost all of these CRUD cases with Rails scaffolding or say Django admins. So I started to look around for Rails/Django-like framework but for Windows Forms applications (ofcourse I understand that "rich client" application development significantly differs from a web development and I'm not expecting anything really similar). I was surprised that except for a variety of ORMs (let's call it Model-layer) it seems like I'm left with little choice when it comes to View-Controller layer. Maybe I'm missing something? PS. I evaluated Visual Studio DataSet Designer, but it seems to work only for the most simple cases, and requires additional code for any slightly nontrivial task. (added) so far I've found: TrueView for .NET (thanks to Vijay Patel) NConstruct

• setNeedsDisplayInRect: paints a white rectangle only

  - by Ion Tichy

  Hi, I'm still a little fresh to CoreGraphics programming, so please bear with me. I'm trying to write an application, which allows the user to rub stuff off an image with the finger. I have the basic functionality nailed down, but the result is sluggish since the screen is redrawn completely every time a touch is rendered. I did some research and found out that I can refresh only a portion of the screen using UIView's setNeedsDisplayInRect: method. This does call drawRect: as expected, however everything I draw in the drawRect: following the setNeedsDisplayInRect: is ignored. Instead, the area in the rect parameter is simply filled with white. No matter what I draw inside, all I end up with is a white rectangle. In essence, this is what I do: 1) when user touches screen, this touch is rendered into a mask 2) when the drawRect: is called, the image is masked with that mask There must be something simple I'm overlooking, surely?

• jQuery Ajax: Copy - Paste thingy

  - by tsiger

  Hi everyone, I have a form where a check an input field for its value and then i do an Ajax call using the typewatch plugin ( a small little thing which detects that the user has stopped typing after a predefined interval ). It works great. As this field is a "coupon discount" in an order form, the value could be entered by copy pasting the "coupon code" from an email or something. It also works with Ctrl+C - Ctrl+V for Copy and paste but not when a user selects the text with the mouse, clicks copy from the context menu and then paste from this menu. Is there a way in jQuery to check for this kind of behaviour in jQuery somehow?
