• Finding which files were "FIXED"and how many times between two specific date by using Trac?

  - by mkafkas

  I need to find out that how many times and which files are fixed or changed due to a bug between two specific dates in an open source project which uses Trac. I selected Webkit project for that purpose. (https://trac.webkit.org/) However, it can be any open source project. What can I do for that? How do I start? Do i have to use version control systems like svn or git for intergration? I am kinda newbie for these bug-tracking and issue-tracking systems.

  I have products : offer_id in javascript and am getting value of offer_id dynamically. Let say I get products : 12345 but now instead of that I want it to be as products : ;12345, than how can this be achieved in javascript.

• C++ for games

  - by Bi

  Hi I am a relatively newbie in C++ and worked in the game industry for a few months. I am looking to get back to the industry and understand that one needs to be a very good C++ programmer (mainly bcos of how competitive it is to get into making games). I was wondering if there are really good websites online that would help with that. Basically I am looking for something that would help me MASTER C++ concepts as well as help me be a good coder through programming examples that I can code. Thanks Bi

• C# How to place a comma after each word but the last in the list

  - by user576712

  I totally new to C# and learning as I go. I am stuck on issue which I'm hoping an experienced programmer can help. I have added a CheckedListBox to my form and added a collection of 6 items to it.

• Using TDD: "top down" vs. "bottom up"

  - by Christian Mustica

  Since I'm a TDD newbie, I'm currently developing a tiny C# console application in order to practice (because practice makes perfect, right?). I started by making a simple sketchup of how the application could be organized (class-wise) and started developing all domain classes that I could identify, one by one (test first, of course). In the end, the classes have to be integrated together in order to make the application runnable, i.e. placing necessary code in the Main method which calls the necessary logic. However, I don't see how I can do this last integration step in a "test first" manner. I suppose I wouldn't be having these issues had I used a "top down" approach. The question is: how would I do that? Should I have started by testing the Main() method? If anyone could give me some pointers, it will be much appreciated.

• YUI Image Loader Images Above Fold Not Loading Until Scroll event.

  - by Mike

  I have a function that is called on the window.onload event to create a group of images and render via the scroll event. function LoadImages(){ var foldGroup = new YAHOO.util.ImageLoader.group(window, 'scroll'); for(var i=0; i<someCounter; i++){ var locationId = locationsArr[i]; foldGroup.registerSrcImage('Location_' + locationId, GetImageDomain()+'/templates/Includes/imagehandler.ashx?locationId=' + locationid); } foldGroup.foldConditional = true; foldGroup.addTrigger(window, 'resize'); } The problem I'm having is that when the page loads, the images "above the fold" are not rendered until I scroll. Is there any tips on troubleshooting this? I'm totally not a js/frontend guy :) Thanks in advance!

• View / ViewModel - what is the sense (in a WPF control)?

  - by TomTom

  Not as funny as it sounds. Normally the View / ViewModel should decouple the presentation from the business logic. Good. Now, a Control in WPF is basically invisible unless made different (with the exceptions of UserControl and Window that have XAML directly attached). The Style is putting in the "visual presentation" - which basically means a Control does not need a view mechanism as WPF already has one? In addition. the ViewModel is actually part of the Control, or? Just fighting with that stuff. I know in ASP.NET, WinForms the separation makes a lot of sense - but there, basically, controls HAVE an intrinsic look. In WPF, I have some where it makes sense (derived from UserControl), but for the majority of the controls I write, the View & ViewModel look like pretty much totally superflous thanks to the already presenting view mechanism.

• Conditionally setting the font color of an item in a drop down box in JSF

  - by Greg

  I'm a newbie to web programming, so please bear with me. I am using JSF 1.2 and I want to conditionally set the color of the items in my drop down list. In other words, I have a collection of items that, along with a key and a value, also have a boolean property, warning, that is dynamically set by user action. I want the drop down to show all of the items, but those whose warning property is set to true should be displayed in red. I assume I have to extend the SelectItem class to add in the boolean property. How do I then conditionally set the color of the font of those items whose warning property is set to true in my JSP pages? Thanks in advance

• Started with a local git repo now I want to push my changes to a remote server

  - by Eliseo Soto

  Hi, I started a new project and created a local git repo with "git init" and now I have a few branches and everything works great. However since my webhosting company offers git hosting (if you're curious https://support.eapps.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=203) I'd like to push my entire repo to their servers to have a backup in the cloud in case something bad happens to my local repo. How can I make the remote repo the "origin" since the repo was started locally? Hope my question makes sense. Thanks, a Git newbie.

• which MVC for coldfusion?

  - by mrjayviper

  newbie to MVC here. so please be gentle. I want to move one of our existing apps (currently located in http://www.companywebsitegoeshere.com/myapp1) to MVC. As can be seen in the URL, there are many apps running in the website which I intend to move at some stage. I don't have write access to the wwwroot (/var/www/html in my case) and the webserver is used by multiple developers across the company. I'm hoping I can have the MVC framework core files/folders + my app all located in in 1 subfolder. In the case of myapp1, all the filers and folders will be inside /var/www/html/myapp1 subfolder. Can you please point me to the right direction (links/guides/docs/videos/etc)? I've looked at several like cfwheels/mach-ii/fw1 but they seemed requires wwwroot access. Thanks! :)

• Ability to Choose From Multiple SQLite DBs for Iphone Application

  - by Mark

  I am working on the design and implementation of an iPhone application ( a newbie, but I am getting the hang of it) where a person can download specific contact information about teachers based on their majors. The information is currently on different edu websites. And I have exported the information into SQLite databases. Is it possible to develop the application that when it is first initiated, it can give the user the option of which particular SQLite database they want for their application? Or if not, would it be better to merge all the DBs into one DB, and allow the user the option of downloading specific information from the SQLite db. I see that the db's can be downloaded into an app, but have yet to find a solution where there can be an option to download from different SQLite dbs. Thanks!

• Need help on how to setup my packages and projects in eclipse

  - by jax

  I am new to Java and am making a license generator. This is my current setup. com.example.licensegenerator.client (used by the client application) :LicenseLoader (no Main method) :LicenseDownloader (no Main method) com.example.licensegenerator.server.keys (used by the server) :ProductKeyGenerator(Main method) com.example.licensegenerator.server.license (used on the server also) :LicenseGenerator(Main method) com.example.licensegenerator.lib (Shared classes between client and server) :Contants (no main) Now I have a few questions. Is it OK to have multiple Main() methods in a single project? Will I be able to compile them to different .jar files? (In this case I need two different jars for the server) Is there a better way to setup the packages? And a totally unrelated question, with exceptions, is it better to handle them right then and there or throw them and let the main method catch them all (the program cannot recover if an error occurs)

• Haskell, list of natural number

  - by Hellnar

  Hello, I am an absolute newbie in Haskell yet trying to understand how it works. I want to write my own lazy list of integers such as [1,2,3,4,5...]. For list of ones I have written ones = 1 : ones and when tried, works fine: *Main> take 10 ones [1,1,1,1,1,1,1,1,1,1] How can I do the same for increasing integers ? I have tried this but it indeed fails: int = 1 : head[ int + 1] And after that how can I make a method that multiplies two streams? such as: mulstream s1 s2 = head[s1] * head[s2] : mulstream [tail s1] [tail s2]

• Preventing entire JOINed MYSQL query from failing when one field is missing within a WHERE clause

  - by filip o

  I am doing a couple of joins with a variable in the WHERE clause. I'm not sure if I am doing everything as efficiently as I could, or even using the best practices but my issue is that half my tables have data for when tableC.type=500, and the other half don't resulting in the entire query failing. SELECT tableA.value1 , tableB.value2, tableC.value3 FROM tableA JOIN tableB ON tableB.id=tableA.id JOIN tableC ON tableC.id=tableB.id WHERE tableA.category=$var && tableC.type=500; What I would like to happen is to still get tableA.value1 and tableB.value2 even if there is no field in tableC with a type=500. any thoughts? i'm totally stumped as how to approach this...

• Syncronise Server Seconds with JS Clients

  - by imperium2335

  I would like to drive a setTimeout loop based on the time of the server, seconds only. So when the seconds on the server is 30, some function is run on all clients. It is vital that they do not become totally out of sync with the server, as there will be a CRON job running on the server every, say, 45 seconds which is important to the system functioning correctly. It is ok if a client is out by a few seconds with the server, client do not need to be synced to each other. I am using Jquery library. Hope this makes sense!

• Can't find .js file in my mainBundle?!

  - by Nic Hubbard

  This is driving me crazy as I cannot figure out what in the world is going on. I load up files form you main bundle all the time, xml files, html files, etc. But, now I am trying to get the contents of a javascript file but it can never find it. I am using: NSData *jsData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"global" ofType:@"js"]]; if (jsData) { NSLog(@"%@", jsData); } else { NSLog(@"Can't find file"); return; } Even checking the [[NSBundle mainBundle] pathForResource:@"global" ofType:@"js"] string returns null. My globaly.js file is in my Resources folder, the exact location where my other files are location that work totally fine using the above method. Why can't it find my js file?

• Validating parameters to a bash script

  - by nickf

  I'm a total newbie to doing any bash scripting, but I came up with a basic one to help automate the process of removing a number of folders as they become unneeded. #!/bin/bash rm -rf ~/myfolder1/$1/anotherfolder rm -rf ~/myfolder2/$1/yetanotherfolder rm -rf ~/myfolder3/$1/thisisafolder This is evoked like so: ./myscript.sh <{id-number}> The problem is that if you forget to type in the id-number (as I did just then), then it could potentially delete a lot of things that you really don't want deleted. Is there a way you can add any form of validation to the command line parameters? In my case, it'd be good to check that a) there is one parameter, b) it's numerical, and c) that folder exists; before continuing with the script.

• What causes VB6 "Run-Time Error '5': Invalid Procedure Call or Argument"

  - by cundh2o

  In VB6, users occasionally receive this error and I am unable to reproduce it. Run-Time Error '5': Invalid Procedure Call or Argument I am referencing the "MSWord 10 Object Library" and sometimes this error occurs at some point after the application has opened MSWord 2002. However, this app has referenced the MSWord 10 Object Library for years, and this error just started occurring in the last few months. I am assuming I have introduced a bug somewhere, but no idea what might be causing it. The error does not occur very often and cannot be reproduced by a user when I am standing there. The error forces the app to totally shut down. Users are running Windows XP

• About first-,second- and third-class value

  - by forest58

  First-class value can be passed as an argument returned from a subroutine assigned into a variable. Second-class value just can be passed as an argument. Third-class value even can't be passed as an argument. Why should these things defined like that? As I understand, "can be passed as an argument" means it can be pushed into the runtime stack;"can be assigned into a variable" means it can be moved into a different location of the memory; "can be returned from a subroutine" almost has the same meaning of "can be assigned into a variable" since the returned value always be put into a known address, so first class value is totally "movable" or "dynamic",second class value is half "movable" , and third class value is just "static", such as labels in C/C++ which just can be addressed by goto statement, and you can't do nothing with that address except "goto" .Does My understanding make any sense? or what do these three kinds of values mean exactly?
