• Sharing logic across different platforms

  - by Pranz

  Hello all, We have a business logic that works with the file systems on OS that we want to implement on both Linux and Windows platforms. The language we have selected is Python for Linux and C# for Windows. GUI is not a priority for now. We were looking for ways to abstract the business logic in a way that we dont have to repeat the business logic (ofcourse I understand since it is related to file system, some code will differ from platform to platform). Any ideas on how to implement it? Is C/C++ the only option. We dont want to use Java. Thanks, Pranz

• Converting table based layout into a div/css based one.

  - by nimo9367

  I'm supposed to rewrite the UI for a rather large web application. The thing is that the layout is completely based on tables and if I could somehow, semi automatically, convert the tables into divs it would save me a huge amount of time. What are the best practices when doing something like this? Is this a good idea at all? The application use layout files (containing something similar to helpers) that are parsed into html at runtime and the application itself also output html at specific places. So the work will consist of converting these helpers and the htmloutput code within the application.

• Using 'ref code' related to the spinner option chosen

  - by user1508541

  I am trying to add a spinner function in a trial app which compares the frequency charts of earphones. I am trying to extract the info from " http://www.headphone.com/learning-center/build-a-graph.php " website. what I want to do is make the spinner work like the drop down list in the mentioned website. On further inspection what I found was that every dropdown element is provided with a unique code that is called when the particular element is selected. I need help in replicating the same in an android spinner.

• change label text from a VB6 binary (not source code)

  - by Jun

  Hi, we have a VB6 binary executable that comes with no source code. And we need to change the label text for that VB6 application from "AAA" to "BBB". Is there any way or tools that can do that? The closest tool I can find right now is microsoft UISpy, it can read all the other elements but not the label. I hope there is a tool that can change the resource in the .exe so that the label "AAA" will read "BBB". Or is it possible to write a wrapper application, it will launch the .exe, examine the application screen for "AAA" and change that to "BBB"? Thank you for your help!

• Is there any way to view PHP code (the actual code not the compiled result) from a client machine?

  - by Columbo

  This may be a really stupid question...I started worrying last night that there might be someway to view PHP files on a server via a browser or someother means on a client machine. My worry is, I have an include file that contains the database username and password. If there were a way to put the address of this file in to a browser or some other system and see the code itself then it would be an issue for obvious reasons. Is this a legitimate concern? If so how do people go about preventing this?

• [multiple issues] Customizing Xcode [fonts, code sense, and more]

  - by wwrob

  How can I make code completion case-sensitive? How can I make Ctrl-k kill the content of the line and the new line character? How can I make backspace always delete only one character, no matter what it is? Right now, it deletes spaces in chunks equal to my indent level. How to change the indentation style in file templates? I like to have the opening brace on its own line. How can I make the font aliased? EDIT: Issues 4 and 5 are solved. 1 through 3 are still open.

• Why did this code still work?

  - by bstullkid

  Some old code that I just came across: MLIST * new_mlist_link() { MLIST *new_link = (MLIST * ) malloc(sizeof(MLIST)); new_link->next = NULL; new_link->mapi = NULL; new_link->result = 0; } This was being called to build a linked list, however I noticed there is no statement: return new_link; Even without the return statement there, the list still got built properly. Why did this happen? EDT: Platform: Mandriva 2009 64bit Linux 2.6.24.7-server GCC 4.2.3-6mnb1

Okay, what I wanna ask you is that is there a way to start a sample as a project in the Eclipse? I mean like clicking a project file in c# or a solution file. Here is my folder which I unzipped the code, \android-sdk-windows\samples\android-8\NotePad There are three folders and one file in the folder, \res, \src, \tests, and AndroidManifest.xml Or, do I need to make a new android project and import (or add files? maybe) them?

• Game Objects Talking To Each Other

  - by PhilCK

  What is a good way of dealing with objects and having them talk to each other? Up until now all my games hobby/student have been small so this problem was generally solved in a rather ugly way, which lead to tight integration and circular dependencies. Which was fine for the size of projects I was doing. However my projects have been getting bigger in size and complexity and now I want to start re-using code, and making my head a simpler place. The main problem I have is generally along the lines of Player needs to know about the Map and so does the Enemy, this has usually descended into setting lots of pointers and having lots of dependencies, and this becomes a mess quickly. I have thought along the lines of a message style system. but I cant really see how this reduces the dependencies, as I would still be sending the pointers everywhere. Thanks. PS: I guess this has been discussed before, but I don't know what its called just the need I have.

• Format MySQL code inside PHP string

  - by JohnA

  Is there any program IDE or not that can format MySQL code inside PHP string e.g. I use PHPStorm IDE and it cannot do it. It does that for PHP and MYSQL but not for MYSQL inside php string. I am ready to use new IDE because now i have to manually format hundreds of database requests that are one line and not readable. Only criteria for my choice is that ide can do that automatically. <?php ... $request1 = "select * from tbl_admin where admin_id= {$_SESSION['admin_id']} and active= 1 order By admin_id Asc"; ... ?> should become <?php ... $request1 = "SELECT * FROM tbl_admin WHERE admin_id = {$_SESSION['admin_id']} AND active = 1 ORDER BY admin_id ASC"; ... ?>

• Angularjs code/naming conventions

  - by Dalorzo

  Does anyone know if exists any official or most accepted reference for Angular naming conventions to use when we build our applications? Angular has a lot of different type of components such as filters, directives, services and so on. Wouldn't you agree that having a reference naming convention when we implement them in our applications will make sense? For example: If we need to create new filters how should we name them like [Something]Filter or filter[Something] or something else? And same applies for Controllers, Services, Directives and so on. Other things I wonder about is if variables/functions that belongs to the scope should have an special prefix or suffix. In some situations it may be useful to have a way to differentiate them from functions and other (none angular code).

• Basic View Switch Code Crashes iPhone simulator

  - by Ouija

  I've been trying to switch two views from two separate view controllers for a while and it never works, the simulator always crashes to the home screen. I'm using Xcode 3.2.5 and this is my code - SwitchViewsViewController.h #import <UIKit/UIKit.h> #import "SecondViewController.h" @interface SwitchViewsViewController : UIViewController { } -(IBAction)pushButton; @end SwitchViewsViewController.m #import "SwitchViewsViewController.h" #import "SecondViewController.h" @implementation SwitchViewsViewController -(IBAction)pushButton { SecondViewController *screen = [[SecondViewController alloc] initWithNibName:nil bundle:nil screen.modalTransitionStyle = UIModalTransitionStyleCoverVertical; [self presentModalViewController:screen animated:YES] [screen release]; } SecondViewController.h #import <UIKit/UIKit.h> @interface SecondViewController : UIViewController { } -(IBAction)pushBack; @end SecondViewController.m #import "SecondViewController.h" @implementation SecondViewController -(IBAction)pushBack{ [self dismissModalViewControllerAnimated:YES]; } In interface builder, all i've done is linked the file's owner classes and the buttons. Also made the SwitchViewsViewController load first, and not MainWindow. Everything builds but when I try to run the app it crashes and sends it to the home screen. Can anyone help me with this?

• Problem while compiling the code

  - by Atul

  Can someone points me the problem in the code when compiled with gcc 4.1.0. #define X 10 int main() { double a = 1e-X; return 0; } I am getting error:Exponent has no digits. When i replace X with 10, it works fine. Also i checked with g++ -E command to see the file with preprocessors applied, it has not replaced X with 10. I was under the impression that preprocessor replaces every macro defined in the file with the replacement text with applying any intelligence. Am I wrong? I know this is a really silly question but I am confused and I would rather be silly than confused :). Any comments/suggestions.

• Add Method to Built In Class

  - by Evorlor

  I am pretty sure this is not doable, but I will go ahead and cross my fingers and ask. I am trying to add a method to a built in class. I want this method to be callable by all of the built in class's subclasses. Specifically: I have a JButton, a JTextPane, and other JComponents. I want to be able to pass in a JDom Element instead of a Rectangle to setBounds(). My current solution is to extend each JComponent subclass with the desired methods, but that is a LOT of duplicate code. Is there a way I can write the following method just one time, and have it callable on all JComponent objects? Or is it required that I extend each subclass individually, and copy and paste the method below? public void setBounds(Element element) { this.setBounds(Integer.parseInt(element.getAttribute( "x").toString()), Integer.parseInt(element .getAttribute("y").toString()), Integer .parseInt(element.getAttribute("width").toString()), Integer.parseInt(element.getAttribute("height") .toString())); }

• super-space-optimized code

  - by Will

  There are key self-contained algorithms - particularly cryptography-related such as AES, RSA, SHA1 etc - which you can find many implementations of for free on the internet. Some are written to be nice and portable clean C. Some are written to be fast - often with macros, and explicit unrolling. As far as I can tell, none are trying to be especially super-small - so I'm resigned to writing my own - explicitly AES128 decryption and SHA1 for ARM THUMB2. What patterns and tricks can I use to do so? Are there compilers/tools that can roll-up code?

• C++ code visualization

  - by bobobobo

  A sort of follow up/related question to this. I'm trying to get a grip on a large code base that has hundreds and hundreds of classes and a large inheritance hierarchy. I want to be able to see the "main veins" of the inheritance hierarchy at a glance - not all the "peripheral" classes that only do some very specific / specialized thing. Visual Studio's "View Class Diagram" makes something that looks like a train and its sprawled horizontally across the screen and isn't very organized. You can't grok it easily. I've just tried doxygen and graphviz but the results are .. somewhat similar to Visual Studio. I'm getting sweet looking call graphs but again too much detail for what I'm trying to get. I need a quick way to generate the inheritance hierarchy, in some kind of collapsible view.

• Disabling identity (auto-incrementing) on integer primary key using code first

  - by gw0

  I am using code first approach in a ASP.NET MVC 3 application and all integer primary keys in models (public int Id { get; set; }) are by default configured as an identity with auto-incrementing. How to disable this and enable a way to manually enter the integer for the primary key? The actual situation is that the Id integers have a special meaning and I would therefore like to have them choosable at creation and later editable. It would be ideal if in case the integer is not given at creation time it is auto-incremented, else the specified value is used. But editable primary fields is my primary need. Is there any way to do this elegantly in ASP.NET MVC 3?

• Problem with sending "SetCookie" first in php code

  - by Camran

  According to this manual: http://us2.php.net/setcookie I have to set the cookie before anything else. Here is my cookie code: if (isset($_COOKIE['watched_ads'])){ $expir = time()+1728000; //20 days $ad_arr = unserialize($_COOKIE['watched_ads']); $arr_elem = count($ad_arr); if (in_array($ad_id, $ad_arr) == FALSE){ if ($arr_elem>10){ array_shift($ad_arr); } $ad_arr[]=$ad_id; setcookie('watched_ads', serialize($ad_arr), $expir, '/'); } } else { $expir = time()+1728000; //20 days $ad_arr[] = $ad_id; setcookie('watched_ads', serialize($ad_arr), $expir, '/'); } As you can see I am using variables in setting the cookie. The variables comes from a mysql_query and I have to do the query first. But then, if I do, I will get an error message: Cannot modify header information - headers already sent by ... The error points to the line where I set the cookie above. What should I do?a

• Best practices to keep up a diverging branch of code

  - by JS_is_bad

  I'm in a situation where some minor patches I've submitted to an open-source project were ignored or explicitly not accepted. I consider them useful, but more important is that I need the functionality they implement. I don't want to push my ideas and suggestions anymore to the main contributors, because I don't want to turn this into an ego issue. I've decided that my best bet would be just to use what I wrote for my own purposes. I don't want to fork the whole source code tree because I like how things are generally working, I'm just not happy with details. But I do realize that the project will evolve and I would like to use the new features that will eventually appear. I understand that I'll have to merge all new things into my own source tree. Are there any best practices for this scenario?
