• Configuration Log4j: ConsoleAppender to System.err?

  - by Gerard

  I saw that one of our tools uses a ConsoleAppender to System.err next to System.out in it's log4j configuration. Fragments of the configuration: <appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender"> <!-- Log to STDOUT. --> <param name="Target" value="System.out"/> .... <appender name="CONSOLE_ERR" class="org.apache.log4j.ConsoleAppender"> <!-- Log to STDERR. --> <param name="Target" value="System.err"/> In Eclipse this results in double messages to the console, so I believe that is of no use, right? On the Linux server I see only one message to the PuTTY console, so where would that System.err message go to?

• Finding the closest grid coordinate to the mouse onclick with javascript/jQuery

  - by Acorn

  What I'm trying to do is make a grid of invisible coordinates on the page equally spaced. I then want a <div> to be placed at whatever grid coordinate is closest to the pointer when onclick is triggered. Here's the rough idea: I have the tracking of the mouse coordinates and the placing of the <div> worked out fine. What I'm stuck with is how to approach the problem of the grid of coordinates. First of all, should I have all my coordinates in an array which I then compare my onclick coordinate to? Or seeing as my grid coordinates follow a rule, could I do something like finding out which coordinate that is a multiple of whatever my spacing is is closest to the onclick coordinate? And then, where do I start with working out which grid point coordinate is closest? What's the best way of going about it? Thanks!

• FormEditor receiving NULL IEditorInput object

  - by Gabriel Parenza

  Hi, I have extended IEditorInput class to define my own IEditorInput object. Furthermore, I have extended FormEditor class. I have view where I am displaying my application objects. Whenever user double clicks on items on view, I intend to display more details for this application object on the editor, which is a FormEditor. Problem I am facing is that I am receiving IEditorInput object as NULL inside extended FormEditor class. Can someone please tell me what I am doing wrong? Code: CustomFormEditor extends FormEditor CustomEditorInput extends IEditorInput In View class: PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().openEditor(new CustomEditorInput("test"),"editor.id"); Thanks, Gaurav.

• How to stop toggle event from being fired multiple times on mouseenter/mouseleave?

  - by Clean

  Hi, I'm using jQuery to toggle the visibility of a using the jQuery toggle method. The toggle is fired on the mouseenter and mouseleave event, thus creating the effect of the div to fold out on mouseenter and fold in on mouseleave. Problem is, if the user drags the mouse over the a few times and then leaves the , the div will toggle in and out several times. This can happen if the user accidentally moves around the mouse pointer in the are. Do anyone have any idea on how I can avoid this behavior? Thanx!

• identifying the type

  - by Gokul

  Hi, In my application, there is a inheritance hierarchy in which only the classes that are at the end of the inheritance chain are non-abstract classes. Also there is some usage of boost::variant. I want to write a function which takes a pointer and a Type and says whether the object belongs to that type. For example template< typename Type, bool TypeisAbstract, typename ptrType > bool checkType( ptrType* t) { return ( typeid(*t) == typeid(Type) ); } template< typename Type, typename ptrType > bool checkType<Type, true, ptrType>( ptrType* t) { return ( dynamic_cast<Type*>(t) != NULL ); } Now if there is a boost variant, i want to find out whether the boost variant stores that particular type. Can someone help me with that? Thanks, Gokul.

• Escaping ampersands in URLs for HttpClient requests

  - by jpatokal

  So I've got some Java code that uses Jakarta HttpClient like this: URI aURI = new URI( "http://host/index.php?title=" + title + "&action=edit" ); GetMethod aRequest = new GetMethod( aURI.getEscapedPathQuery()); The problem is that if title includes any ampersands (&), they're considered parameter delimiters and the request goes screwy... and if I replace them with the URL-escaped equivalent %26, then this gets double-escaped by getEscapedPathQuery() into %2526. I'm currently working around this by basically repairing the damage afterward: URI aURI = new URI( "http://host/index.php?title=" + title.replace("&", "%26") + "&action=edit" ); GetMethod aRequest = new GetMethod( aURI.getEscapedPathQuery().replace("%2526", "%26")); But there has to be a nicer way to do this, right? Note that the title can contain any number of unpredictable UTF-8 chars etc, so escaping everything else is a requirement.

• Overriding events of excel sheet using VBA

  - by Rashmi Pandit

  Hi, I need to programmatically override the following events of a worksheet: BeforeDoubleClick SelectionChange BeforeRightClick I have been able to override the OnActivate event using the following code: sheet.OnSheetActivate = "MyOwn_Activate" Private Sub MyOwn_Activate() myForm.Show End Sub I have implemented BeforeDoubleClick on similar lines: sheet.OnDoubleClick = "My_BeforeDoubleClick" Private Sub My_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean) ... End Sub However, an 'argument not optional' error is thrown at run-time when user double clicks a cell on the sheet. Can someone please suggest how should I pass the paramters? In addition, I am not able to find event names for SelectionChange & BeforeRightClick. I tried: sheet.BeforeRightClick = "My_BeforeRightClick" sheet.SelectionChange = "My_SelectionChange" But, both the above lines do not work. Any help/ suggestion is greatly appreciated. Thanks :)

• What's the fastest way to check the availability of a SQL Server server?

  - by mwolfe02

  I have an MS Access program in use in multiple locations. It connects to MS SQL Server tables, but the server name is different in each location. I am looking for the fastest way to test for the existence of a server. The code I am currently using looks like this: ShellWait "sc \\" & ServerName & " qdescription MSSQLSERVER > " & Qt(fn) FNum = FreeFile() Open fn For Input As #FNum Line Input #FNum, Result Close #FNum Kill fn If InStr(Result, "SUCCESS") Then ... ShellWait: executes a shell command and waits for it to finish Qt: wraps a string in double quotes fn: temporary filename variable I run the above code against a list of server names (of which only one is normally available). The code takes about one second if the server is available and takes about 8 seconds for each server that is unavailable. I'd like to get both of these lower, if possible, but especially the fail case as this one happens most often.

• How do I create a MessageBox in C# ?

  - by Nick Stinemates

  I have just installed C# for the first time, and at first glance it appears to be very similar to VB6. I decided to start off by trying to make a 'Hello, World!' UI Edition. I started in the Form Designer and made a button named "Click Me!" proceeded to double-click it and typed in MessageBox("Hello, World!"); I received the following error: MessageBox is a 'type' but used as a 'variable' Fair enough, it seems in C# MessageBox is an Object. I tried the following MessageBox a = new MessageBox("Hello, World!"); I received the following error: MessageBox does not contain a constructor that takes '1' arguments Now I am stumped. Please help.

• Storing member function pointers of derived classes in map

  - by Kiran Mohan

  Hello, I am trying to implement a factory for two classes Circle, Square both of which inherits from Shape. class Shape { public: virtual static Shape * getInstance() = 0; }; class Circle : public Shape { public: static const std::string type; Shape * getInstance() { return new Circle; } }; const std::string Circle::type = "Circle"; class Square : public Shape { public: static const std::string type; Shape * getInstance() { return new Square; } }; const std::string Square::type = "Square"; I want to now create a map with key as shape type (string) and value as a function pointer to getInstance() of the corresponding derived class. Is it possible? Thanks, Kiran

• asp.net compare validators to allow comma and dot (both!) as decimal separator

  - by DanC

  I am using a compare validator, which validates that the entered number is a valid double and also validates it against a given value (greater than zero). I am validating money amounts. Because of the location where the app is used, the locale sets the comma as the decimal separator. The problem is that when a user enters the value using the numeric keyboard, the number gets written with the dot as decimal separator, and is rejected by the validation. I'd like to have this validation done before triggering a postback (like a customvalidator would) and accepting both separators. Any ideas? Thanks

• WPF DependencyProperty event before content changed

  - by morsanu

  First I will explain the context of the problem, because you might be able to point me in a better direction. I need to implement a undo-redo like system on an object. The object has a series of dependency properties. Some are double, int, string but some are also of DependencyObject type. I need to save the value of the property before it is changed, and for this I added the CoerceValueCallback. public static readonly DependencyProperty MyBackgroundProperty = DependencyProperty.Register("MyBackground", typeof(MyCustomizableBackground), typeof(MyComponent), new UIPropertyMetadata(default(MyCustomizableBackground), null, new CoerceValueCallback(OnPropertyChanged))); In OnPropertyChanged I save the value before it's changed. MyCustomizableBackground is the DependencyObject that has also some dependency properties. The problem is that in this case, where I have a custom object as a property, the OnPropertyChanged method isn't triggered, but when I have a common type, it is triggered.

• How can I avoid floating the same content twice?

  - by Randall Bohn

  My Kynetx app uses float_html() to put up a box full of content. rule float_box { select when pageview ".*" pre { content = << <div id='messagebox'> <h3>Floating Message Box</h3> <ul id='my_list'></ul> </div> >>; } float_html("absolute","top:25px","right:20px",content); } rule fill_box { select when pageview ".*" foreach ["alpha","bravo","charlie"] setting (list_item) append("#my_list", "<li>#{list_item}</li>"); } The app (a421x27) is used from a bookmarklet. If you click the bookmarklet twice on the same page you get double content. Is there any way to detect that the box is already on the screen and reuse it?

• VB.NET function that takes other functions as a parameter, and executes them

  - by rob

  Hello, Is there a way in vb.net to create a sub/function that will take as an argument some kind of pointer to another function, and allow this new sub/function to execute the passed function? What I have are 10-12 xml-rpc functions I am calling against a remote server. Each of these functions has different argument lists (one takes 1 string, another might take 3 strings and one int, etc). All of them return an object. As I am calling these, it seems like it should be able to be factored better. For instance, everytime I call any of these functions, I want to test the return value for a session drop, and do something to try and reconnect to the remote system, etc. Using .net 3.5 Thanks! -R

• Strange Scala error.

  I tried to create abstract turn based Game and abstract AI: abstract class AGame { type Player type Move // Player inside def actPlayer : Player def moves (player : Player) : Iterator[Move] def play (move : Move) def undo () def isFinished : Boolean def result (player : Player) : Double } abstract class Ai[Game <: AGame] { def genMove (player : Game#Player) : Game#Move } class DummyGame extends AGame { type Player = Unit type Move = Unit def moves (player : Player) = new Iterator[Move] { def hasNext = false def next = throw new Exception ("asd") } def actPlayer = () def play (move : Move) { } def undo () { } def isFinished = true def result (player : Player) = 0 } class DummyAi[Game <: AGame] (game : Game) extends Ai[Game] { override def genMove (player : Game#Player) : Game#Move = { game.moves (player).next } } I thought that I have to use this strange type accessors like Game#Player.

• How to Access a Private Variable?

  - by SoulBeaver

  This question isn't meant to sound as blatantly insulting as it probably is right now. This is a homework assignment, and the spec sheet is scarce and poorly designed to say the least. We have a function: double refuel( int liter, GasStation *gs ) { // TODO: Access private variable MaxFuel of gs and decrement. } Sound simple enough? It should be, but the class GasStation comes with no function that accesses the private variable MaxFuel. So how can I access it anyway using the function refuel? I'm not considering creating a function setFuel( int liter ) because the teacher always complains rather energetically if I change his specification. So... I guess I have to do some sort of hack around it, but I'm not sure how to go about this without explicitely changing the only function in GasStation and giving it a parameter so that I can call it here. Any hints perhaps?

• Passing big multi-dimensional array to function in C

  - by kirbuchi

  Hi, I'm having trouble passing a big array to a function in C. I declare: int image[height][width][3]={}; where height and width can be as big as 1500. And when I call: foo((void *)image,height,width); which is declared as follows: int *foo(const int *inputImage, int h, int w); I get segmentation fault error. What's strange is that if my values are: height=1200; width=290; theres no problem, but when they're: height=1200; width=291; i get the mentioned error. At 4 bytes per integer with both height and width of 1500 (absolute worst case) the array size would be of 27MB which imo isn't that big and shouldn't really matter because I'm only passing a pointer to the first element of the array. Any advice?

• How do I include 2 tables in one LocalStorage item?

  - by Noor

  I've got a table that you can edit, and I've got a simple code saving that list when you're done with editing it. (the tables have the contenteditable on) The problem I've stumbled upon is that if I double click on enter, the table gets divided into two separate tables with the same ID. This causes the code I'm using to set the localStorage to only store one of the tables (I assume the first).. I've thought of different solutions and I wonder if someone could point out the pro's and con's (if the solutions even works that is). Make a loop that checks the page after tables and stores them into an array of localStorage-items.. I'd have to dynamically create a localStorage item for each table. Take the whole div that the tables are in, and store that in the localStorage, when a user revisits the page, the page checks after the items in storage and displays the whole divs. Any suggestions you have that can beat this :).. (but no cache, it has to be with the localStorage!) Thanks

• Accessing structure through pointers [c]

  - by Blackbinary

  I've got a structure which holds names and ages. I've made a linked-list of these structures, using this as a pointer: aNode *rootA; in my main. Now i send **rootA to a function like so addElement(5,"Drew",**rootA); Because i need to pass rootA by reference so that I can edit it in other functions (in my actual program i have two roots, so return will not work) The problem is, in my program, i can't say access the structure members. *rootA->age = 4; for example doesnt work. Hopefully you guys can help me out. Thanks!

• Why are my RSpec specs running twice?

  - by James A. Rosen

  I have the following RSpec (1.3.0) task defined in my Rakefile: require 'spec/rake/spectask' Spec::Rake::SpecTask.new(:spec) do |spec| spec.libs << 'lib' << 'spec' spec.spec_files = FileList['spec/**/*_spec.rb'] end I have the following in spec/spec_helper.rb: require 'rubygems' require 'spec' require 'spec/autorun' require 'rack/test' require 'webmock/rspec' include Rack::Test::Methods include WebMock require 'omniauth/core' I have a single spec declared in spec/foo/foo_spec.rb: require File.dirname(__FILE__) + '/../spec_helper' describe Foo do describe '#bar' do it 'be bar-like' do Foo.new.bar.should == 'bar' end end end When I run rake spec, the single example runs twice. I can check it by making the example fail, giving me two red "F"s. One thing I thought was that adding spec to the SpecTask's libs was causing them to be double-defined, but removing that doesn't seem to have any effect.

• [Objective-C] Primitive question, (void) init method.

  Hi, I have a question in Objective-C. I'm using init method Apple recommended style. - (id)initMyClass: (int)a { if (self = [super init]) { // a... } return self; } Init method returns own object pointer. Then, if the object will not be refered from any objects, can empty return method(void) be better? - (void)initMyClass: (int)a { if ([super init] != nil) { // a... } } I want to know about that, if init method doesn't return self, what problem will occur?
