  • if else-if making code look ugly any cleaner solution?

    - by Vishal
    I have around 20 functions (is_func1, is_fucn2, is_func3...) returning boolean I assume there is only one function which returns true and I want that! I am doing: if is_func1(param1, param2): # I pass 1 to following abc(1) # I pass 1 some_list.append(1) elif is_func2(param1, param2): # I pass 2 to following abc(2) # I pass 1 some_list.append(2) ... . . elif is_func20(param1, param2): ... Please note: param1 and param2 are different for each, abc and some_list take parameters depending on the function. The code looks big and there is repetition in calling abc and some_list, I can pull this login in a function! but is there any other cleaner solution? I can think of putting functions in a data structure and loop to call them.

  • Drupal Error After Logging In

    - by Kim
    Hello everyone. I'm kinda new to using drupal and i'm just wondering why I kind of get this error on my new site. See i have this website under WampServer running drupal6-16. Everytime I log in with my pre-created admin account 'admin01' pass: 'admin01' i get redirected to the WampServer localhost which appears to be unusual since the header does not have the WampServer logo. I already tried creating a new drupal website with the same database and the same thing happens. Also, I tried creating another website with a new database but I copied the other website's theme and other contents and the same thing happens. Help me please. I am losing my grip on this. :( Note: I have the same website running on one PC and i am just trying to run it on another PC by copying all its contents. The original copy is working perfectly but I can't seem to get the hook on my new copies to work on other PCs.

  • C# Array Maximum

    - by Betamoo
    I have 2 arrays named Arr1 and Arr2 in C#. They are of the exact same dimensions... I need to get the element of Arr1 corresponding to maximum of elements in Arr2 beginning with given indices ... e.g Get indices of the max of Arr2 [ 1 , 10 , 3 , i , j ] for all i,j Return Arr1 [ 1 , 10 , 3 , i , j ] Of course I need the elegant solution (not the "loop for them" one...) Please Note: I do not want to loop through the arrays, because it is 11 dimensional!!.. the code will be ugly and error prone.. and I may run out of variable names :)

  • One-to-many relationship related to many tables

    - by Andrey
    I have a scenario where: there are two (or more) tables that represent independent items. lets say Users and Companies Both of these tables need addresses stored. Each one can have one or more address In a normal 1 to many scenario Addresses table woudl just have a UserId or a CompanyId creating a normal 1 to many relationship. In this case i have a few approaches i can think of the Addresses table could have both a UserId and a CompanyId and only one would be used for each record. 2 keys could be used ObjectId and ObjectType So Object id would have a UserId or a CompanyId, and ObjectType woudl be User or Company Create an ObjectTable and add ObjectId to Users and Companies. Addresses would then have an OjbectId I do not really like any of these solutions. i am wondering what is the best approach here. On another note i will most likely user linqtosql for my data access layer.

  • Correct Path for Git Remote Add from Amazon EC2 Instance to OSX Client Machine

    - by filmnut
    I'm trying to do a git remote add from a repository that sits on a remote Amazon AMI back to a cloned copy of the SAME repository that is sitting on my local OSX machine. I'm confused about what file path to use. I assume it's something like: git remote add my_clone <OSX_User_Name>@<OSX_HOST_NAME>:<PATH_TO_CLONED_REPO> I obviously know what my <OSX_User_Name> is, and I can figure out my <PATH_TO_CLONED_REPO>, but I have no idea how to determine a <OSX_HOST_NAME> that would actually work. Can I just put in my external IP address, followed by my machine's internal IP address? (Note that I'm working behind a router.) Is ssh:// the correct protocol? Do I need to set up ssh access from the Amazon EC2 machine to the local OSX machine?

  • For what purposes have YOU used T4?

    - by Chris Melinn
    T4 has existed for several years in Visual Studio, but doesn't get a lot of attention. However, for those that know it, there seems to be some very creative and useful purposes. I am researching some different ways that T4 is used, and I would appreciate to hear how YOU may have used it for real life scenarios. I am primarily interested in non-standard and creative uses. Some interesting examples: Phil Haack uses T4 to create static CSS files from .less To Generate WPF and Silverlight Dependency Properties using T4 Templates Note: I realize this is a discussion-oriented question, but the answers could be helpful to others. I have tagged it as subjective and also marked as "community wiki", so please allow the question to remain open. Thanks!

  • No difference between nullable:true and nullable:false in Grails 1.3.6?

    - by knorv
    The following domain model definition .. class Test { String a String b static mapping = { version(false) table("test_table") a(nullable: false) b(nullable: true) } } .. yields the following MySQL schema .. CREATE TABLE test_table ( id bigint(20) NOT NULL AUTO_INCREMENT, a varchar(255) NOT NULL, b varchar(255) NOT NULL, PRIMARY KEY (id) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; Please note that a and b get identical MySQL column definitions despite the fact a is defined as non-nullable and b is nullable in the GORM mappings. What am I doing wrong? I'm running Grails 1.3.6.

  • Which is the best and appropriate way to write the code in Winforms ?

    - by Harikrishna
    What is the best way to write the code ? (1) Like directly writing the code in the button_click() event. or (2) Make the function of that code which I write in button_click() event and write this function in one class and then that function I should call in the button_Click() event.Like is it called three-tired approach to write the code ? Like in button_Click() event I write the code to save the records in csv file from datatable.So I should write that code in button_Click() event or I should make one new function and one new class and write that code in that function which is the new class and calling that function in button_Click() event. This is only one example but I am talking about all the code written in my application that which is the appropriate and best way to write the code and what are the benefits ? Note that I write the code in Winforms with c#.

  • How to find dynamically loaded modules (the static ones) programatically in windows

    - by Ryan Rohrer
    I'm trying to port the unix utility ldd to windows, because dependency walker and cygcheck don't quite give me the usage I'm looking for. (also for the learning experience) Ive been looking all over MSDN, for a windows API that lists dll dependencies of an executable, or even the storage format in the complied exe (just to filter it out), but I've been unable to find anything. If anyone knows what API call windows uses for listing modules to load, or what patterns I can search for in an executable to find modules to load, please help me out :) thanks! -note: I'm not looking to profile for dynamic modules, just list the ones that are required at runtime

  • Regex for template tag with attributes

    - by Funkmyer
    Hi, I haven't found my answer after reading through all of these posts, so I'm hoping one of you heavy hitter regex folks can help me out. I'm trying to isolate the tag name and any attributes from the following string format: {TAG:TYPE attr1="foo" attr2="bar" attr3="zing" attr4="zang" attr5="zoom" ...} NOTE: in the above example, TAG will always be the same and TYPE will be one of several preset strings (e.g. share,print,display etc...). TAG and TYPE are uppercased only for the example but will not be case sensitive for real.

  • How access Ajax generated source ?

    - by Rorchackh
    Hello everyone, I created a php file that return dynamically generated text. This text is returned with a div id. When I retrieve that text using Ajax as responseText. I would like to access the properties of that div using javascript, which is impossible since that new text is not added to the DOM. My question is, how can i access that div using either raw javascript or frameworks (am somewhat familiar with jQuery) ? It may be useful to note that the div can be accessed using CSS. Thank you.

  • Thread Jobs in Java

    - by Bragaadeesh
    Hi, I want to spawn 200 threads simultaneously in Java. What I'm doing right now is running into a loop and creating 200 threads and starting them. After these 200 gets completed, I want to spawn another 200 set of threads and so on. The gist here is that the first 200 threads I spawned need to be FINISHED before spawning the next set. I tried the code below, but its not working for(int i=0;i<200;i++){ Thread myThread = new Thread(runnableInstance); myThread.start(); } for(int i=0;i<200;i++){ Thread myThread = new Thread(runnableInstance); myThread.start(); } Note: I have intentionally put the for loop Twice, but the desired effect I intend is not happening simply because the second for loop is executed before the first set of threads end their execution. Please advise

  • What does "static" mean in the context of declaring global template functions?

    - by smf68
    I know what static means in the context of declaring global non-template functions (see e.g. What is a "static" function?), which is useful if you write a helper function in a header that is included from several different locations and want to avoid "duplicate definition" errors. So my question is: What does static mean in the context of declaring global template functions? Please note that I'm specifically asking about global, non-member template functions that do not belong to a class. In other words, what is the difference between the following two: template <typename T> void foo(T t) { /* implementation of foo here */ } template <typename T> static void bar(T t) { /* implementation of bar here */ }

  • Is it possible to access JSON properties with relative syntax when using JSON defined functions?

    - by Justin Vincent
    // JavaScript JSON var myCode = { message : "Hello World", helloWorld : function() { alert(this.message); } }; myCode.helloWorld(); The above JavaScript code will alert 'undefined'. To make it work for real the code would need to look like the following... (note the literal path to myCode.message) // JavaScript JSON var myCode = { message : "Hello World", helloWorld : function() { alert(myCode.message); } }; myCode.helloWorld(); My question is... if I declare functions using json in this way, is there some "relative" way to get access to myCode.message or is it only possible to do so using the literal namespace path myCode.message?

  • Determine version of dll linked against

    - by ron
    According to this article, the version of a referenced dll is embedded in the exe file. Using ProcExp, I can see that the runtime loaded dll is indeed the latest dll available on my machine, but I'm interested to know the linked version. As a side note, I built the project using the VS9 msbuild, and interested in the VC runtime (msvcr90.dll) version. In the VC9 redist folder it is 9.0.30729.1, runtime the .4926 is loaded. My questions are: Is there any tool with which I can extract the dll version linked to (from the dll/exe)? Which version does VS link to by default? The one found in its redist folder? Thank you.

  • Windows service thread not updating database until complete

    - by dfarney
    I have a windows service with a FileSystemWatcher. When a new file is dropped in my folder a new thread is created, started, and I begin processing the file. Throughout this process I am making updates to the database (Linq to SQL) to keep track of the file's processing progress. Problem is none of my database updates are reflected throughout the process, just an update after everything has been completed. Any ideas? Note: when doing dev/testing my code was in an aspx page and worked great, but when I put it in a windows service I no longer get the progress updates. Thanks!

  • Lightbox effect with Jquery

    - by Sarfraz
    Hello, I just wanted to know how to create lightbox effect with JQuery, I mean let's suppose I have div, and when i click some button it shows that div at the center of the browser window across all browsers with a transparent background behind. In this div i could show just about anything including a form, image, or some text so it becomes sort of stylish alert box. So how to: Center a div across all browsers and behind this div put a transparent background covering entire screen of browser. Note: I know there are a host such effects out there, i just want to know how do i create a simple centered div with transparent background behind. So please don't suggest any pre-made solution, would be great if you could write sample code for that. Thanks

  • Boost Shared Pointer: Simultaneous Read Access Across Multiple Threads

    - by Nikhil
    I have a thread A which allocates memory and assigns it to a shared pointer. Then this thread spawns 3 other threads X, Y and Z and passes a copy of the shared pointer to each. When X, Y and Z go out of scope, the memory is freed. But is there a possibility that 2 threads X, Y go out of scope at the exact same point in time and there is a race condition on reference count so instead of decrementing it by 2, it only gets decremented once. So, now the reference count newer drops to 0, so there is a memory leak. Note that, X, Y and Z are only reading the memory. Not writing or resetting the shared pointer. To cut a long story short, can there be a race condition on the reference count and can that lead to memory leaks?

  • Is an iPhone Call Recorder theoretically possible?

    - by Adam Dempsey
    NOTE: I know neither the iPhone SDK or Objective C, just wondering if possible. I know obviously it would have to be on a Jailbroken device anyway, but it is technically possible for a iPhone call recording application to be made, or is it not possible to hook into the calls or the audio input/output? I know obviously there would be no 'official' way of doing it and certainly not from an App Store application. And I know there are call recording apps which place outgoing calls through their own servers. Just wondering if the reason it doesn't exist yet is just because no-one has coded it or if it's not actually possible?

  • How to implement a set ?

    - by nomemory
    I want to implement a Set in C. Is it OK to use a linked list, when creating the SET, or should I use another approach ? How do you usually implement your own set (if needed). NOTE: If I use the Linked List approach, I will probably have the following complexities for my operations: init : O(1); destroy: O(n); insert: O(n); remove: O(n); union: O(n*m); intersection: O(n*m); difference: O(n*m); ismember: O(n); issubset: O(n*m); setisequal: O(n*m); O(n*m) seems may be a little to big especially for huge data... Is there a way to implement my Set more efficient ?

I have tried textread,fscanf and a few other matlab commands but the result is that they all read each row in decimal format and create a 840946*1 array.I want to create a 840946*125 array to compute a column wise sum. Kindly help, Thanks!

  • Why do we need a private constructor?

    if a class has a private constructor then it cant be instantiated. so, if i dont want my class to be instantiated and still use it, then i can make it static. what is the use of a private constructor ? Also its used in singleton class, except that, is there any othe use ? (Note : The reason i am excuding the singleton case above is because I dont understand why do we need a singleton at all ? when there is a static class availble. You may not answer for my this confusion in the question. )

  • What to use to write tests? [Rails]

    - by yuval
    I asked a question about different testing frameworks yesterday. This question can be found here. Now that I have a better understanding of the different frameworks, I have a very simple question: With a basic understanding, but very limited experience with writing tests with rails' built in testing framework (basic assertions), would it be okay for me to jump directly to testing with RSpec, Webrat, and Cucamber? Thank you! As a side note: yes, this is an opinion based question, but I feel that the input received to this question is valuable enough to the community to keep this question open. Thanks.

  • How can an SQL query return data from multiple tables

    - by Fluffeh
    I would like to know how to get data from multiple tables in my database, what types of methods are there to do this, what are joins and unions and how are they different from one another? When should I use each one compared to the others? I am planning to use this in my (for example - PHP) application, but don't want to run multiple queries against the database, what options do I have to get data from multiple tables in a single query? Note: I am writing this as I would like to be able to link to a well written guide on the numerous questions that I constantly come across in the PHP queue, so I can link to this for further detail when I post an answer. The answers cover off the following: Part 1 - Joins and Unions Part 2 - Subqueries Part 3 - Tricks and Efficient Code

  • Best place/area to store file for Trail period

    - by hotveryspicy
    I need to have a trial period (7 days) in my application. From this I came to know that you can do that by keeping permanent file, database or shared preference. Where do I keep that file so that the user isn't able to see/delete it. If I put that logic in Sharedpreference or a file with a path "data/data/packagename", when the application is uninstalled then all history will be lost. Any other workaround/ideas? Note: there is no server, application works locally with no Internet.
