• C# Solution - How many projects?

  - by Oskar Kjellin

  Hey, I googled this a little but couldn't find a good result. Right now I'm building a web site and I'm trying to make it as correct as possible from a design point of view from the beginning. The problem I'm now facing is that when deciding to start with logging I needed a project to place this code in. As I could not find a suitable place in my currect projects I thought: hey, why not a logging class library? Is there a general guideline on how many projects you should have? I know this would be a rather small project but it would be nice to entirely get it out of my way! Any hints are appreciated :)

• Eclipse complains android:scrollbars and android:fadingEdge do not allow Strings - includes code.

  - by emanuel

  Having a problem in Eclipse with regards to an XML file. Eclipse complains that android:scrollbars and android:fadingEdge do not allow Strings. I checked the Android developer site and they do in fact accept strings in the xml file. A related question posed had the problem where there was a missing :android after xmlns. As you can see from the code the line beginning with xmlns is correct I believe. Here is the complete file contents: <?xml version="1.0" encoding="UTF-8"?> <com.example.todolist.TodoListItemView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp" android:scrollbars="verticle" android:textColor="@color/notepad_text" android:fadingEdge="verticle" />

• Obtaining IP addresses in Bittorrent

  - by Legend

  I am trying to get a list of IP addresses serving or downloading a file. What I did was to contact a tracker like openbittorrent.com to get the following (as part of the scrape file): B%00%00%0C%5F%B1%B1l%CAGa%84S%CB%B0%9BG%84%3BE:0:1 Now, the long string in the beginning is the info hash. As a next step, I did this: http://tracker.sometracker.com/announce?info_hash=B%00%00%0C%5F%B1%B1l%CAGa%84S%CB%B0%9BG%84%3BE It gave me back the following. So far so good. The message contained this: d8:completei0e10:downloadedi0e10:incompletei2e8:intervali1931e12:min intervali965e5:peers12:U????????^@^@e Can someone tell me what should I be doing after this to get the IP addresses currently serving the file or downloading it?

• Eclipse Code Templates with Cobol

  - by Bruno Brant

  People, My team is just beginning to learn how to use COBOL on Eclipse (as part of the Rational Developer for System Z package) and one of our most desired features are code templates or code snippets. What we'd like to have is a code completion based on snippets just like we have on Java. For example, when I type try and hit ctrl-space Eclipse shows me a list of completion options, where one of those is create a try/catch block. Well, in COBOL one could leverage this when creating, for example, embedded SQL blocks, like EXEC SQL SELECT field, field, field, FROM table WHERE field = value, field = value END-EXEC. However, for some reason, it seems that Eclipse treats COBOL a little differently (no wonder why) from other languages. As such, when looking for the code templates in the preferences menu for COBOL, its appearance is very different from the Java one. The question is: how does one uses Eclipse's code templates with COBOL?

• How to reset iPhone simulator

  - by Stefan Mayr

  My app uses the location service. To test what is happening when the user presses 'Don't allow' when the simulator asks for the permission to access the location service (when the app is started for the first time) I need to reset the simulator. This because the question was answered at the beginning of the development process with allow. So no more questions are asked. Reseting the Simulator with "Reseting Content and Settings.." don't bring back the question at the start. What I am doing wrong? thx in advance

• Silverlight RIA Services. Query fails on large table but works with Where clause

  - by FauxReal

  I have a somewhat large table, maybe 2000 rows by 50 columns. When using the most basic imaginable RIA implementation. Create one-table Model Create DomainService Drop datagrid onto MainPage.xaml Drop datasource onto datagrid Ctrl-F5 I get this error: System.ServiceModel.DomainServices.Client.DomainOperationException: Load operation faild for query. Value cannot be null. Error is much larger, but thats the beginning of it. The weird thing is that if I narrow the results down with a where clause on the GetQuery, it works fine. In fact six different querys which together result in all of the rows being called works fine also. So basically, I'm sure its not some sort of rogue row. Why do I get this "Value cannot be null" error if I query the whole table? Thanks

• Experience using Yii framework for actual PHP project

  - by desireco

  I've been using Code Igniter for my PHP projects, when I start them from the beginning. It is very nice framework, saves me a lot of work and let me have low level access if I need to do something special. Code Igniter is also faster then similar frameworks by order of magnitude. I came across Yii framework which claims to be even faster and easier and prettier and whatever. I never heard of it and I was wondering if someone used it in some real life project and have practical experience that he is willing to share.

• Javacript in html - Using single quote inside another single quote

  - by Ashish Nair

  document.getElementById("img").innerHTML="< img src='/sitepath/"+imgg+".jpg' width='72' height='44' onclick='alert('hello');' />"; The above code is my javascript. Problem is printing hello or any other string. If I just type 123 in place of hello, it does give alert. But am not able to use a string like hello there. Normally a string in an alert function is kept inside quotes ' ' but the entire content is inside double quotes and I have already used single quote at the beginning of onclick function. I tried using Escape character ("\") but it didnt help. Any suggestions?

• How can I flush the output of disp in Octave?

  - by Nathan Fellman

  I have a program in Octave that has a loop - running a function with various parameters, not something that I can turn into matrices. At the beginning of each iteration I print the current parameters using disp. The first times I ran it I had a brazillion warnings, and then I also got these prints. Now that I cleaned them up, I no longer see them. My guess is that they're stuck in a buffer, and I'll see them when the program ends or the buffer fills. Is there any way to force a flush of the print buffer so that I can see my prints?

• Anobody succeeded in using ICEFaces with jQuery?

  - by hubertg

  Basically jquery is usable with IceFaces. Then only problem arises when partial updates of the page are used. For example you have a panelgroup where a jquery datepicker element (jquery UI datepicker plugin) is used. If the panelGroup is visible from the beginning it's no problem. The jquery call to jQuery(".datepicker").datepicker finds the input and jquery can do it's magic. But if the panelGroup is shown because of a partial update of the page (because the visible propery is changed) jquery is not called again. Does anybody has a solution to this problem? Basically the idea would be that jquery is run each time the dom has changed.

• g++ not linking header files properly

  - by cambr

  I am using cygwin libraries to run C and C++ programs on Windows. gcc runs fine, but with g++, I get a long list of errors. I think these erros are because of linking problems with C libraries.

• Pass by reference in Boost::Python

  - by Fabzter

  Hi everybody. Consider something like: struct Parameter { int a; Parameter(){a = 0} void setA(int newA){a = newA;} }; struct MyClass { void changeParameter(Parameter &p){ p.setA(-1);} }; Well, let's fast forward, and imagine I already wrapped those classes, exposing everything to python, and imagine also I instantiate an object of Parameter in the C++ code, which I pass to the python script, and that python script uses a MyClass object to modify the instance of Parameter I created at the beginning in the C++ code. After that code executes, in C++ Parameter instance is unchanged!!! This means it was passed by value (or something alike :S), not by reference. But I thought I declared it to be passed by reference... I can't seem to find Boost::Python documentation about passing by reference (although there seems to be enough doc about returning by reference...). Can anyone give some hint or pointer please?

• Code folding for LaTeX in Emacs

  - by ShreevatsaR

  Is there an Emacs minor-mode (or piece of elisp code) that lets you selectively hide/show environments while in LaTeX mode? For instance, I would like to move to the beginning of a long \begin{figure} block, hit a keystroke, and have the contents of that figure environment hidden from view. Similarly with \begin{proof} and so on, and ideally even with \subsections. Is this possible? I just tried hs-minor-mode, allout-mode, and outline-minor-mode, but most of them don't recognize LaTeX's environments, e.g. hs-minor-mode fails with "scan error: unbalanced parentheses". I would prefer not to have to enter explicit folding marks like {{{ as in folding-mode. [Ideally it would be great if the folding were persistent, but I see that that question doesn't have an accepted answer yet.]

• Recommendations for keeping a build server updated

  - by gareth_bowles

  As a guy who frequently switches between QA, build and operations, I keep running into the issue of what to do about operating system updates on the build server. The dichotomy is the same on Windows, Linux, MacOS or any other o/s that can update itself via the internet: The QA team wants to keep the build server exactly as it is from the beginning of the product release cycle to the end, since installing updates could destabilize the server and means that successive builds aren't made against the same baseline. The ops team wants the software to be deployed on a system with all the latest security patches; this can mean that the software isn't deployed on exactly the same version of the o/s that it was built on. I usually mitigate this by taking release candidate builds and installing them on a test server that has a completely up-to-date o/s, repeating the automated tests that are run on the build server and doing some additional system level testing to make sure everything looks good before deployment. However, this seems inefficient to me; does anyone have a better way ?

• Deploying Sinatra app on Dreamhost/Passenger with custom gems

  - by darkism

  I've got a Sinatra app that I'm trying to run on Dreamhost that makes use of pony to send email. In order to get the application up and running at the very beginning (before adding pony), I had to gem unpack rack and gem unpack sinatra into the vendor/ directory, so this was my config.ru: require 'vendor/rack/lib/rack' require 'vendor/sinatra/lib/sinatra' set :run, false set :environment, :production set :views, "views" require 'public/myapp.rb' run Sinatra::Application I have already done gem install pony and gem unpack pony (into vendor/). Afterwards, I tried adding require 'vendor/sinatra/lib/pony' to config.ru only to have Passenger complain about pony's dependencies (mime-types, tmail) not being found either! There has to be a better way to use other gems and tone down those long, ugly, redundant requires. Any thoughts?

• iphone settings disappear

  - by cagreen

  I have created an app which uses Application Settings and user defaults following the example in the book "Beginning iPhone Development". In some cases my settings seem to disappear. If I launch the simulator I can go into settings and see it, I can then open my app and my settings can be read from within the app. If I then leave my app and go back into the settings screen I can no longer see the settings for my app! I'm new to iPhone dev, is there something obvious that I'm overlooking? Thanks.

• Winforms ComboBox autocomplete search multiple parts of string

  - by studiothat

  Very similar question to this one... http://stackoverflow.com/questions/522521/autocomplete-for-combobox-in-wpf-anywhere-in-text-not-just-beginning but my issue is for windows-forms rather than WPF. I have a winforms databound combox working great with autocomplete list coming from the data items in the combobox. Of course the client wants it to work "better", and that means that they want the autocomplete to work by searching and showing autocomplete options for any matching (contains()) string not just the starting string (startswith()) I know it's probably not just a property that can be set in the combobox, but can anyone point me in the right direction?

• ASP.NET MVC vs. ASP.NET 4.0

  - by CodeMonkey

  I watched this webcast recently, and I got the sense that a lot of the "cool stuff" from ASP.NET MVC is getting pulled back into the ASP.NET framework. At the moment I'm setting the ground-work for a project at my company using ASP.NET MVC, but after watching this, I'm beginning to wonder if that's the right choice, and whether it would behoove me to wait for ASP.NET 4.0. I realize ASP.NET MVC 2.0 is getting close to an actual release. If High-Testability, loose coupling, and having Full control of our HTML are top priorities, which should I choose, ASP.NET 4.0 or ASP.NET MVC?

• Efficiency Question for an Ajax App

  - by Kubi

  Hi, Currently I am dealing with a web application which uses a txt file as a database for testing for now. But we will connect it to a server later on. My question is, if there is a more efficient way to get my objects than the way I am using now. During the page_init I am getting all my objects into a Collection as List, then I am populating the ajax toolkit accordion objects in the page with that. I have some client side buttons which fires callbacks for getting some other objects to populate the accordions in an update panel. And I am using .net Collections too much like dictionary and list, I am wondering if using arrays is more efficient. Could you advise me about how to make this site better and faster ? Is it better or possible to initialize those TravelP objects in javascript at the beginning and use it like that ? Any comments would be greatly appreciated, Thanks

• Split textarea content into two at maxlength and flow excedant content in another textarea

  - by user1057339

  Wondering if its possible to create a short simple and sweet cross-browser jQuery (1.6) function that would split #textarea1 content into two by preserving the characters that amount to less than its var maxlength limit and transfering the remaining characters that exceed its maxlength limit in #textarea2. #textarea1 can push excedant in #textarea2, but if #textarea1 contains less than the maxlength limit, by default it wont get filled up with #textarea2 content, but you would have the option programatically to override this. I am just beginning to scratch the surface of jQuery but I noticed that this simple javascript can nearly do the trick, minus the free-flowing character movement. Scratching my head on this one. Thx a heap for any help. DC

• Language Design: Combining Gotos and Functions

  - by sub

  I'm designing and currently rethinking a low-level interpreted programming language with similarities to assembler. I very soon came across the functions/loops/gotos decision problem and thought that while loops like while and for would be too high-level and unfitting, gotos would be too low level, unmaintainable and generally evil again. Functions like you know them from most languages that have return values and arguments aren't fitting in the language's concept either. So I tried to figure out something between a function and a goto which is capable of Recursion Efficient loops After some thinking I came up with the idea of subroutines: They have a beginning and an end like a function They have a name but no arguments like a goto You can go into one with jump and go out of it again before its end with return (doesn't give back any result, only stops the subroutine) Handled just like normal code - Global scope like goto So I wanted to know: Is the idea above good? What are the (dis)advantages? Would there be a better combination of function and goto or even a completely new idea?

• Nice name for `decorator' class?

  - by Lajos Nagy

  I would like to separate the API I'm working on into two sections: 'bare-bones' and 'cushy'. The idea is that all method calls in the 'cushy' section could be expressed in terms of the ones in the 'bare-bones' section, that is, they would only serve as convenience methods for the quick-and-dirty. The reason I would like to do this is that very often when people are beginning to use an API for the first time, they are not interested in details and performance: they just want to get it working. Anybody tried anything similar before? I'm particularly interested in naming conventions and organizing the code.

• Naming conventions and field naming question for CakePHP

  - by jphenow

  Okay so two questions very related: 1) Does following the naming convention for classes, controllers, database fields, etc. affect the framework's ability to work the way it was intended? (I'm a little new to working with a framework from the beginning of app development) 2) This question is more important if 1 is a yes. Say I have a table, A, that has 2 foreign keys pointing at the same table, B, but different entries (they're like edges of a graph that point at two vertices) how would I follow the naming convention of their database fields? All I can think to do is something like vertex_1_id and vertex_2_id but I don't know how the framework would handle that if the naming conventions are necessary for its functioning correctly.
