  • MacOSX + Eclipse: Rename variable function not working

    - by MIsha
    Good day. I have Eclipse PHP Galileo for Mac OSX, 32bit Cocoa version. The problem is the rename function doesn't work properly. While editing PHP file I choose Refactor-Rename menu or a rename hotkey and Eclipse doesn't offer me to rename a variable, instead a rename file dialog appears. Tried to configure hotkeys but no luck. If you do know the solution – please tell. Thank you.

  • Setting variables in shell script by running commands

    - by rajya vardhan
    >cat /tmp/list1 john jack >cat /tmp/list2 smith taylor It is guaranteed that list1 and list2 will have equal number of lines. f(){ i=1 while read line do var1 = `sed -n '$ip' /tmp/list1` var2 = `sed -n '$ip' /tmp/list2` echo $i,$var1,$var2 i=`expr $i+1` echo $i,$var1,$var2 done < $INFILE } So output of f() should be: 1,john,smith 2,jack,taylor But getting 1,p,p 1+1,p,p If i replace following: var1 = `sed -n '$ip' /tmp/list1` var2 = `sed -n '$ip' /tmp/list2` with this: var1=`head -$i /tmp/vip_list|tail -1` var2=`head -$i /tmp/lb_list|tail -1` Then output: 1,john,smith 1,john,smith Not an expert of shell, so please excuse if sounds childish :)

  • Removing $_SESSION['layout']['action'] globally from all users!

    - by sologhost
    Ok, I am storing a session variable like so to load up users layouts faster if it's set instead of calling the database. But since the layout can be changed via the Administrator, I'd like to be able to globally remove all sessions where $_SESSION['layout']['action'] is set for all users. $_SESSION['layout']['action'] = array(a ton of indexes and mulit-dimensional arrays); Now, I know it's being stored into my database sessions table, there's a column for session_id, last_update, and data. So, question I have is how to remove that session array key ['action'] from all users. Using $_SESSION = array(); session_destroy(); Does not work. Basically, session_start() is being loaded on every page load, so I just want to remove all ['action'] keys from ['layout']. Is this possible to do? Thanks

  • set variables in an MVC application?

    - by Melissa
    I am trying to learn about the Orchard MVC application. I see the following code but cannot understand what it is doing. Can someone explain what this: User.As<UserPart>().Record.UserName = value; means? public class UserEditViewModel { [Required] public string UserName { get { return User.As<UserPart>().Record.UserName; } set { User.As<UserPart>().Record.UserName = value; } } [Required] public string Email { get { return User.As<UserPart>().Record.Email; } set { User.As<UserPart>().Record.Email = value; } } public IContent User { get; set; } }

  • iPhone slide view passing variables

    - by sebastyuiop
    Right, I'm trying to make an app that has a calculation that involves a stopwatch. When a button on the calculation view is clicked a stopwatch slides in from the bottom. This all works fine, the problem I can't get my head around is how to send the recorded time back to the previous controller to update a textfield. I've simplified the code and stripped out most irrelevant stuff. Many thanks. CalculationViewController.h #import <UIKit/UIKit.h> @interface CalculationViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> { IBOutlet UITextField *inputTxt; } @property (nonatomic, retain) UITextField *inputTxt; - (IBAction)showTimer:(id)sender; @end CalculationViewController.m #import "CalculationViewController.h" #import "TimerViewController.h" @implementation CalculationViewController - (IBAction)showTimer:(id)sender { TimerViewController *timerView = [[TimerViewController alloc] init]; [self.navigationController presentModalViewController:timerView animated:YES]; } TimerViewController.h #import <UIKit/UIKit.h> @interface TimerViewController : UIViewController { IBOutlet UILabel *time; NSTimer *myTicker; } - (IBAction)start; - (IBAction)stop; - (IBAction)reset; - (void)showActivity; @end TimerViewController.m #import "TimerViewController.h" #import "CalculationViewController.h" @implementation TimerViewController - (IBAction)start { myTicker = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector:@selector(showActivity) userInfo:nil repeats:YES]; } - (IBAction)stop { [myTicker invalidate]; #Update inputTxt on calculation view here [self dismissModalViewControllerAnimated:YES]; } - (IBAction)reset { time.text = @"0"; } - (void)showActivity { int currentTime = [time.text intValue]; int newTime = currentTime + 1; time.text = [NSString stringWithFormat:@"%d", newTime]; } @end

  • Cross-reference js-object variables when creating object

    - by Ivar Bonsaksen
    Summary: I want to know if it is possible to do something like this: {a: 'A',b: this.a} ...by using some other pointer like {a: 'A',b: self.a} or {a: 'A',b: own.a} or anything else... Full question: I'm trying to extend MyBaseModule using Ext.extend, and need to cross-reference values in the extension object passed to Ext.extend(). Since I'm not yet in context of MyModule, I'm not able to use this to reference the object (See example below line 12). Is there any other way to reference values like this without creating the object first? 1 MyModule = Ext.extend(MyBaseModule, { 2 dataStores: { 3 myDataStore: new Ext.data.Store({...}) 4 }, 5 6 myGridDefinition: { 7 id: 'myGridDefinitionPanel', 8 bodyBorder: false, 9 items: [{ 10 xtype: 'grid', 11 id: 'myGridDefinitionGrid', 12 store: this.dataStores.myDataStore 13 }] 14 } 15 }); Or is the following the only solution? I would like to avoid this if possible, as I find it less readable for large extension definitions. 1 var extensionObject = { 2 dataStores: { 3 myDataStore: new Ext.data.Store({...}) 4 }, 5 6 myGridDefinition: { 7 id: 'myGridDefinitionPanel', 8 bodyBorder: false, 9 items: [{ 10 xtype: 'grid', 11 id: 'myGridDefinitionGrid' 12 }] 13 } 14 }; 15 16 extensionObject.locationsGrid.items[0].store = extensionObject.dataStores.locations; 17 18 MyModule = Ext.extend(MyBaseModule, extensionObject);

  • Math with interpolated variables?

    - by Idan Gazit
    Consider the following sass: $font-size: 18; $em: $font-size; $column: $font-size * 3; // The column-width of my grid in pixels $gutter: $font-size * 1; // The gutter-width of my grid in pixels $gutter-em: #{$gutter / $em}em; // The gutter-width in ems. $column-em: #{$column / $em}em; // The column-width in ems; $foo = $gutter-em / 2; // This results in a value like "1em/2". :( $bar = ($gutter-em / 2); // this doesn't work either, same as above. How can I generate a $foo that works, and that I can reuse further in other expressions?

  • Why do I get this error when trying to set up a class variable

    - by Jennifer
    I'm new to PHP so maybe I am overlooking something here but the following: class someClass { var $id = $_GET['id']; function sayHello() { echo "Hello"; } } gives the following error: Parse error: syntax error, unexpected T_VARIABLE in C:\xampp\htdocs\files\classes.php on line 13 If instead of $_GET['id'] I set the variable $id to a string, everything is fine though.

  • JQuery UI question, how do you add variables into the dialog box

    $('.openDialog').click(function(event){ var width=$(this).attr('width'); var height=$(this).attr('height'); alert(width + ' ' + height); event.preventDefault(); $("#dialog").dialog({autoOpen: false, modal: true}); $('#dialog').dialog('option', 'width', width); $('#dialog').dialog('open'); $('#dialog p').load('http://pagetoload.com/page.html .content'); }); As you can see above i'm trying to open a dialog box with a passed in parameter of width and height, however when I try and pass in the value of width on this line: $('#dialog').dialog('option', 'width', width); it doesn't work, any ideas why or how to get around that? Thanks

  • Passing variables to callback functions

    - by mickyjtwin
    I am trying to write a jQuery plugin, that can be applied to a selector. Within this plugin, there are multiple calls to webservices, where callback methods are required. The problem I am having is maintaining the current context item in the each loop of the selector. (function($){ $.fn.myMethod = function(){ return this.each(function(){ var c = $(this); $.api.methodToCall("", CallbackFunction); }); }; function CallbackFunction(data, result){ // do stuff based on c } })(jQuery); Normally, you would provide the callback function straight away, which allows me to access c, however within the callback function, there potentially is another api call, so it would start to get messy. Is there any way to do this?

  • jQuery .get appends an unknown variable to URL

    - by ILMV
    I'm using this code as the starting point to an overhaul of our JavaScript framework: $("#get").click(function(){ $("#result").html(ajax_load); $.get( "http://www.google.com", {}, function(responseText){ $("#result").html(responseText); }, "html" ); }); But when the request is made it includes a variable within the URL that I am unfarmiliar with, here is what Firebug says it's requesting: http://www.google.com/?_=1268993359215 How do I get rid of this, when we target our internal scripts it's firing a 404 error :-( Cheers!

  • C# class design - expose variables for reading but not setting

    - by James Brauman
    I have a a polygon class which stores a list of Microsoft.Xna.Framework.Vector2 as the vertices of the polygon. Once the polygon is created, I'd like other classes to be able to read the position of the vertices, but not change them. I am currently exposing the vertices through this field: /// <summary> /// Gets the vertices stored for this polygon. /// </summary> public List<Vector2> Vertices { get { return _vertices; } } List<Vector2> _vertices; However you can change any vertex using code like: Polygon1.Vertices[0] = new Vector2(0, 0); or Polygon1.Vertices[0].X = 0; How can I limit other classes to be able to only read the properties of these vertices, and not be able to set a new one to my List? The only thing I can think of is to pass a copy to classes that request it. Note that Vector2 is a struct that is part of the XNA framework and I cannot change it. Thanks.

  • Variable lenght arguments in log4cxx LOG4CXX_ macros

    - by Horacio
    I am using log4cxx in a big C++ project but I really don't like how log4cxx handles multiple variables when logging: LOG4CXX_DEBUG(logger, "test " << var1 << " and " << var3 " and .....) I prefer using printf like variable length arguments: LOG4CXX_DEBUG(logger, "test %d and %d", var1, var3) So I implemented this small wrapper on top of log4cxx #include <string.h> #include <stdio.h> #include <stdarg.h> #include <log4cxx/logger.h> #include "log4cxx/basicconfigurator.h" const char * log_format(const char *fmt, ...); #define MYLOG_TRACE(logger, fmt, ...) LOG4CXX_TRACE(logger, log_format(fmt, ## __VA_ARGS__)) #define MYLOG_DEBUG(logger, fmt, ...) LOG4CXX_DEBUG(logger, log_format(fmt, ## __VA_ARGS__)) #define MYLOG_INFO(logger, fmt, ...) LOG4CXX_INFO(logger, log_format(fmt, ## __VA_ARGS__)) #define MYLOG_WARN(logger, fmt, ...) LOG4CXX_WARN(logger, log_format(fmt, ## __VA_ARGS__)) #define MYLOG_ERROR(logger, fmt, ...) LOG4CXX_ERROR(logger, log_format(fmt, ## __VA_ARGS__)) #define MYLOG_FATAL(logger, fmt, ...) LOG4CXX_FATAL(logger, log_format(fmt, ## __VA_ARGS__)) static log4cxx::LoggerPtr logger(log4cxx::Logger::getRootLogger()); int main(int argc, char **argv) { log4cxx::BasicConfigurator::configure(); MYLOG_INFO(logger, "Start "); MYLOG_WARN(logger, log_format("In running this in %d threads safe?", 1000)); MYLOG_INFO(logger, "End "); return 0; } const char *log_format(const char *fmt, ...) { va_list va; static char formatted[1024]; va_start(va, fmt); vsprintf(formatted, 1024, fmt, va); va_end(va); return formatted; } And this works perfectly but I know using that static variable (formatted) can become problematic if I start using threads and each thread logging to the same place. I am no expert in log4cxx so I was wondering if the LOG4CXX macros are handling concurrent thread access automatically? or do I have to implement some sort of locking around the log_format method? something that I wan't to avoid due to performance implications. Also I would like to ask why if I replace the vsprintf inside the log_format method with vsnprintf (that is more secure) then I get nothing printed? To compile and test this program (in Ubuntu) use : g++ -o loggertest loggertest.cpp -llog4cxx

  • Subclass not seeing superclass' instance variable

    - by hyn
    I have a situation where my subclass is not seeing the superclass' instance variable x. The ivar is obviously @protected by default, so why do I get a compiler error "x undeclared"? If I make this ivar a property then I can access it by self.x. What's worse is sometimes the error disappears, so something in my code is obviously causing this error but I cannot figure it out.

  • Using match variable $1 for a substitution in Perl

    - by justintime
    What is the cleanest way of picking up a match variable form a subsitution in Perl I sometimes find myself writing s/(something)// ; my $x = $1 ; then I realise that if the s/ / / fails $1 might be carrying over a value from a previous match. So I try my $x = 'defaultvalue' ; if ( s/(something)// ) { $x = $1 ; } Is this be cleanest way of doing it.

  • jquery noob problem with variables (scope?)

    - by aharon
    I'm trying to retrieve data from a php file named return that just contains <?php echo 'here is a string'; ?> I'm doing this through an html file containing <!DOCTYPE html> <html> <head> <script src="http://code.jquery.com/jquery-latest.min.js"></script> <script> var x; $.get("return.php", function(data){ x = data; }) function showAlert() {alert(x);} $(document).ready(function(){ alert(x); }); </script> </head> <body> <input type = "button" value = "Click here" onClick="showAlert();"> </body> </html> When the button is clicked it retrieves and displays the code fine, but on the $(document).ready thing, it displays "undefined" instead of the data in return.php. Any solutions? Thanks.
