  • Should I put a try-finally block after every Object.Create?

    - by max
    I have a general question about best practice in OO Delphi. Currently, I put try-finally blocks anywhere I create an object to free that object after usage (to avoid memory leaks). E.g.: aObject := TObject.Create; try aOBject.AProcedure(); ... finally aObject.Free; end; instead of: aObject := TObject.Create; aObject.AProcedure(); .. aObject.Free; Do you think it is good practice, or too much overhead? And what about the performance?

  • Using NetBeans for multiple programming languages

    - by mawg
    I am looking for a cross platform RAD IDE with GUI building. NetBeans looks right (or am aI wrong?). However, I may want to code somethings in C++ and some in Python. It looks like both are supported, but I am not sure if I need to install two copies of NetBeans or if one can handle both programming languages. Sorry it's such a st00pid n00b question - can anyone tell me quickly? Thanks

  • Is it bad practice to initialize a variable to a dummy value?

    - by froadie
    This question is a result of the answers to this question that I just asked. It was claimed that this code is "ugly" because it initializes a variable to a value that will never be read: String tempName = null; try{ tempName = buildFileName(); } catch(Exception e){ ... System.exit(1); } FILE_NAME = tempName; Is this indeed bad practice? Should one avoid initializing variables to dummy values that will never actually be used? (EDIT - And what about initializing a String variable to "" before a loop that will concatenate values to the String...? Or is this in a separate category? e.g. String whatever = ""; for(String str : someCollection){ whatever += str; } )

  • Flexible array members in C - bad?

    - by Lionel
    I recently read that using flexible array members in C was poor software engineering practice. However, that statement was not backed by any argument. Is this an accepted fact? (Flexible array members are a C feature introduced in C99 whereby one can declare the last element to be an array of unspecified size. For example: ) struct header { size_t len; unsigned char data[]; };

  • What's the best practice in case something goes wrong in Perl code?

    - by Geo
    I saw code which works like this: do_something($param) || warn "something went wrong\n"; and I also saw code like this: eval { do_something_else($param); }; if($@) { warn "something went wrong\n"; } Should I use eval/die in all my subroutines? Should I write all my code based on stuff returned from subroutines? Isn't eval'ing the code ( over and over ) gonna slow me down?

  • list all files from directories and subdirectories in Java

    - by Adnan
    What would be the fastest way to list the names of files from 1000+ directories and sub-directories? EDIT; The current code I use is: import java.io.File; public class DirectoryReader { static int spc_count=-1; static void Process(File aFile) { spc_count++; String spcs = ""; for (int i = 0; i < spc_count; i++) spcs += " "; if(aFile.isFile()) System.out.println(spcs + "[FILE] " + aFile.getName()); else if (aFile.isDirectory()) { System.out.println(spcs + "[DIR] " + aFile.getName()); File[] listOfFiles = aFile.listFiles(); if(listOfFiles!=null) { for (int i = 0; i < listOfFiles.length; i++) Process(listOfFiles[i]); } else { System.out.println(spcs + " [ACCESS DENIED]"); } } spc_count--; } public static void main(String[] args) { String nam = "D:/"; File aFile = new File(nam); Process(aFile); } }

  • moving a website built on struts to a CMS

    - by fabiobeta
    Hi. Imagine having developed a classical website with java&struts. Now you customer is learning that redeploying the application to change an image or a text is a significant cost. And it asks to add a function to the site: cms-like handling of the contents (editing, versioning, approved publishing). How would you handle this request? Would you develop it in the webapp? Would you merge the webapp with a CMS? Would tou MOVE the webapp into a cms? Would you run away?

  • How to organize database access code in Android project?

    - by Mladen Jablanovic
    I have created a ContentProvider for my main Sqlite table, pretty much following NotePad example from SDK (although I am not sure whether I will ever be exposing my data to other apps). However, I need to create lots of other, non-trivial queries on that and other tables and views. A good example would be queries to extract some statistics from the base data, averages, totals etc. So what's the best place for this code in an Android project? How it should be related and connected to the Uri-based data access exposed by a Provider? Any good examples out there?

  • Handling missing data

    - by soppotare
    Say I have a simple helpdesk application which logs calls made by users. I would typically have such fields in a table relating to the call e.g. CallID, Description, CustomerID etc. I Would also have a table of customers including CustomerID, Username, Password, FullName etc. Now when a user is deleted from the customers table then the inner join between the calls table and the users table to find out historically which user logged a call would produce no results. How do people usually deal with this? Have seperate customer and useraccount tables Just disable the accounts so the data is still available Record the customers name in the calls table as a seperate field. or any other methods / suggestions?

  • detect a string contained by another discontinuously

    - by SpawnCxy
    Recently I'm working on bad content(such as advertise post) filter of a BBS.And I write a function to detect a string is in another string not continuously.Code as below: $str = 'helloguys'; $substr1 = 'hlu'; $substr2 = 'elf'; function detect($a,$b) //function that detect a in b { $c = ''; for($i=0;$i<=strlen($a);$i++) { for($j=0;$j<=strlen($b);$j++) { if($a[$i] == $b[$j]) { $b=substr($b,$j+1); $c .=$a[$i]; break; } } } if($c == $a) return true; else return false; } var_dump(detect($substr1,$str)); //true var_dump(detect($substr2,$str)); //false Since the filter works before the users do their posts so I think the efficiency here is important.And I wonder if there's any better solution? Thanks!

  • How do you like to define your module-wide variables in drupal 6?

    - by sprugman
    I'm in my module file. I want to define some complex variables for use throughout the module. For simple things, I'm doing this: function mymodule_init() { define('SOME_CONSTANT', 'foo bar'); } But that won't work for more complex structures. Here are some ideas that I've thought of: global: function mymodule_init() { $GLOBALS['mymodule_var'] = array('foo' => 'bar'); } variable_set: function mymodule_init() { variable_set('mymodule_var', array('foo' => 'bar')); } property of a module class: class MyModule { static $var = array('foo' => 'bar'); } Variable_set/_get seems like the most "drupal" way, but I'm drawn toward the class setup. Are there any drawbacks to that? Any other approaches out there?

  • Correct approach to validate attributes of an instance of class

    - by systempuntoout
    Having a simple Python class like this: class Spam(object): __init__(self, description, value): self.description = description self.value = value Which is the correct approach to check these constraints: "description cannot be empty" "value must be greater than zero" Should i: 1.validate data before creating spam object ? 2.check data on __init__ method ? 3.create an is_valid method on Spam class and call it with spam.isValid() ? 4.create an is_valid static method on Spam class and call it with Spam.isValid(description, value) ? 5.check data on setters declaration ? 6.... Could you recommend a well designed\Pythonic\not verbose (on class with many attributes)\elegant approach?

  • Exception handling pattern

    - by treefrog
    It is a common pattern I see where the error codes associated with an exception are stored as Static final ints. when the exception is created to be thrown, it is constructed with one of these codes along with an error message. This results in the method that is going to catch it having to look at the code and then decide on a course of action. The alternative seems to be- declare a class for EVERY exception error case Is there a middle ground ? what is the recommended method ?

  • Creating and Compiling a C++ project on Windows

    - by sc_ray
    I need to work on C++ project on my windows machine. My project will consist of various classes(.h and .cpp) as well as the startup file to start the application. The preliminary design is simple but the application has the potential to gain complexity as time goes by. What I need here is ideas to set up the C++ project compiler/IDE/Makefile etc..etc. as well as some standard tools besides Visual C++ to compile/build/link projects such as these on a Windows OS. Thanks

  • Using try vs if in python

    - by artdanil
    Is there a rationale to decide which one of try or if constructs to use, when testing variable to have a value? For example, there is a function that returns either a list or doesn't return a value. I want to check result before processing it. Which of the following would be more preferable and why? result = function(); if (result): for r in result: #process items or result = function(); try: for r in result: #process items except TypeError: pass; Related discussion: Checking for member existence in Python
