  • Refactored App Engine project - now Eclipse is infinitely building the project without end

    - by Yog
    I renamed some files in my App Engine project and refactored code, changing references to variables. Everything seemed fine until I changed the references in the web.xml for the project. Then I got a complaint about some error with the DataNucleus enhancer and now the project build process is stuck at 22%. I tried stopping Eclipse and restarting but the build process keeps hanging. Any tips on how to clean out whatever it's getting stuck on?

  • VB6's private static in C# ?

    - by blez
    In VB6 there are local static variables that keep their values after the exit of procedure. It's like using public vars but on local block. For example: sub count() static x as integer x = x + 1 end sub After 10 calls, x will be 10. I tried to search the same thing in .NET (and even Java) but there was none. Why? Does it break the OOP model in some way, and is there a way to emulate that.

  • Need an app config file opinion here.....

    - by Chris
    I know that app config is used to provide environmental type of values for process variables. And it is very much key/value oriented. But I have a process (windows service) that uses a skeleton xml template file to produce a fuller version of that file after processesing. What about the idea of including that 'skeleton xml' in the app config file? I am trying to aviod having a standalone xml skeleton file, since it is 'configuration' related, in a way.

  • When I really need to use [NSThread sleepForTimeInterval:1];

    - by Timbo
    Hi there, I have a program that needs to use sleep. Like really needs to. In lieu of spending ages explaining why, suffice to say that it needs it. Now I'm told to split off my code into a separate thread if it requires sleep so I don't lose interface responsiveness, so I've started learning how to use NSThread. I've created a brand new program that is conceptual so to solve the issue for this example will help me in my real program. Short story is I have a class, it has instance variables and I need a loop with a sleep to be depended on the value of that instance variable. Here's what I've put together anyway, your help is very much appreciated :) Cheers Tim /// Start Test1ViewController.h /// #import <UIKit/UIKit.h> @interface Test1ViewController : UIViewController { UILabel* label; } @property (assign) IBOutlet UILabel *label; @end /// End Test1ViewController.h /// /// Start Test1ViewController.m /// #import "Test1ViewController.h" #import "MyClass.h" @implementation Test1ViewController @synthesize label; - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; label.text = @"1"; [NSThread detachNewThreadSelector:@selector(backgroundProcess) toTarget:self withObject:nil]; } - (void)backgroundProcess { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; // Create an instance of a class that will eventually store a whole load of variables MyClass *aMyClassInstance = [MyClass new]; [aMyClassInstance createMyClassInstance:(@"Timbo")]; while (aMyClassInstance.myVariable--) { NSLog(@"blah = %i",aMyClassInstance.myVariable); label.text = [NSString stringWithFormat:@"blah = %d", aMyClassInstance.myVariable]; //how do I pass the new value out to the updateLabel method, or reference aMyClassInstance.myVariable? [self performSelectorOnMainThread:@selector(updateLabel) withObject:nil waitUntilDone:NO]; //the sleeping of the thread is absolutely mandatory and must be worked around. The whole point of using NSThread is so I can have sleeps [NSThread sleepForTimeInterval:1]; } [pool release]; } - (void)updateLabel {label.text = [NSString stringWithFormat:@"blah = %d", aMyClassInstance.myVariable]; // be nice if i could } - (void)didReceiveMemoryWarning {[super didReceiveMemoryWarning];} - (void)viewDidUnload {} - (void)dealloc {[super dealloc];} @end /// End Test1ViewController.m /// /// Start MyClass.h /// #import <Foundation/Foundation.h> @interface MyClass : NSObject { NSString* name; int myVariable; } @property int myVariable; @property (assign) NSString *name; - (void) createMyClassInstance: (NSString*)withName; - (int) changeVariable: (int)toAmount; @end /// End MyClass.h /// /// Start MyClass.h /// #import "MyClass.h" @implementation MyClass @synthesize name, myVariable; - (void) createMyClassInstance: (NSString*)withName{ name = withName; myVariable = 10; } - (int) changeVariable: (int)toAmount{ myVariable = toAmount; return toAmount; } @end /// End MyClass.h ///

  • Interaction between C++ and Rails applications

    - by FancyDancy
    I have two applications: c++ service and a RoR web server (they are both running at same VPS) I need to "send" some variables (and then do something with them) from each other. For exaple, i'm looking for something like this: // my C++ sample void SendMessage(string message) { SendTo("127.0.0.1", message); } void GetMessage(string message) { if (message == "stop") SendMessage("success"); } # Ruby sample # application_controller.rb def stop @m = Messager.new @m.send("stop") end I have never used it before, and i even don't know which technology should i search and learn.

  • Scaffolding Extensions: NoMethodError

    - by marienbad
    Not sure if many people are familiar with Scaffolding Extensions for Ruby, but I've looked through their docs, forums, and even the source code of the Heroku test site, and not found an answer. I made a basic Sinatra app and followed right from the RDoc's instructions: require 'scaffolding_extensions' require 'sinatra/base' class Thingy < Sinatra::Base scaffold_all_models end gives undefined method 'scaffold_all_models' for Thingy:Class (NoMethodError) and I know Scaffolding Extensions is loadable because I can successfully set some config variables in its classes.

  • code style for private methods in c#

    - by illdev
    I just found out, that it seems a common pattern to user UpperFirstLetterPascalCase() for private methods. I for myself, find this completely inconsistent with naming rules of private instance fields and variables and I find it difficult to read/debug, too. I would want to ask, why using a first upper letter for methods could be a better choice than a first lower (doThis())? Just out of curiosity...

  • Using the standard Flash AS3 scrollbar class

    - by WebDevHobo
    Flash has a scrollbar class, documented here: http://help.adobe.com/en_US/AS3LCR/Flash_10.0/fl/controls/ScrollBar.html However, besides listing functions and variables, there's no real explanation of how to hook an instance of this class to a textfield. Everything I've tried either ends up in errors or the scrollbar not showing. The documentation lacks a clear way of how you should bind the textfield and the scrollbar toghether, and CS4 isn't providing any help either. Can someone explain, or link to an example of how scrollbars work with textfield?

  • JavaScript Encapsulation / JQuery

    - by Chris
    I am trying to figure out how to keep my page variables in my application from being defined globally. I've come up with a few methods but am wondering if there is a general standard approach people use. I've got my plugin design pattern down using this approach: http://www.virgentech.com/blog/2009/10/building-object-oriented-jquery-plugin.html. But I'm just not sure how to handle my page level encapsulation.

  • Pros and cons of escaping strategies in symfony

    - by zergu
    I am still not sure in that matter. While turned on we're quite safe but some other problems appear (with passing template variables or counting characters). On the other hand we have magic turned off, everything is clear, but we have to manually escape every variable (that come from untrusted source) in templates. By the way, non-magic solution is used in Ruby-on-Rails. So the question is: when starting a new project in symfony do you disable escaping_strategy and why?

  • C: Random Number Generation - What (If Anything) Is Wrong With This

    - by raoulcousins
    For a simple simulation in C, I need to generate exponential random variables. I remember reading somewhere (but I can't find it now, and I don't remember why) that using the rand() function to generate random integers in a fixed range would generate non-uniformly distributed integers. Because of this, I'm wondering if this code might have a similar problem: //generate u ~ U[0,1] u = ( (double)rand() / ((double)(RAND_MAX)); //inverse of exponential CDF to get exponential random variable expon = -log(1-u) * mean; Thank you!

  • Reading POST data from html form sent to serversocket.

    - by user32167
    i try to write simplest possible server app in Java, displaying html form with textarea input, which after submitting gives me possibility to parse xml typed in that textarea. For now i build simple serversocket based server like that: import java.io.BufferedReader; import java.io.InputStreamReader; import java.io.PrintWriter; import java.net.ServerSocket; import java.net.Socket; public class WebServer { protected void start() { ServerSocket s; String gets = ""; System.out.println("Start on port 80"); try { // create the main server socket s = new ServerSocket(80); } catch (Exception e) { System.out.println("Error: " + e); return; } System.out.println("Waiting for connection"); for (;;) { try { // wait for a connection Socket remote = s.accept(); // remote is now the connected socket System.out.println("Connection, sending data."); BufferedReader in = new BufferedReader(new InputStreamReader( remote.getInputStream())); PrintWriter out = new PrintWriter(remote.getOutputStream()); String str = "."; while (!str.equals("")) { str = in.readLine(); if (str.contains("GET")){ gets = str; break; } } out.println("HTTP/1.0 200 OK"); out.println("Content-Type: text/html"); out.println(""); // Send the HTML page String method = "get"; out.print("<html><form method="+method+">"); out.print("<textarea name=we></textarea></br>"); out.print("<input type=text name=a><input type=submit></form></html>"); out.println(gets); out.flush(); remote.close(); } catch (Exception e) { System.out.println("Error: " + e); } } } public static void main(String args[]) { WebServer ws = new WebServer(); ws.start(); } } After form (textarea with xml and one additional text input) is submitted in 'gets' String-type variable I have Urlencoded values of my variables (also displayed on the screen, it looks like that: gets = GET /?we=%3Cnetwork+ip_addr%3D%2210.0.0.0%2F8%22+save_ip%3D%22true%22%3E%0D%0A%3Csubnet+interf_used%3D%22200%22+name%3D%22lan1%22+%2F%3E%0D%0A%3Csubnet+interf_used%3D%22254%22+name%3D%22lan2%22+%2F%3E%0D%0A%3C%2Fnetwork%3E&a=fooBar HTTP/1.1 What can i do to change GET to POST method (if i simply change it in form and than put " if (str.contains("POST")){" it gives me string like gets = POST / HTTP/1.1 with no variables. And after that, how i can use xml from my textarea field (called 'we')?

  • Check user language selection in NSIS MUI2

    I have multiple language packs in my NSIS installer, using the MUI2 interface. Now I try to select the language pack, which is installed by the "Typical" installation type according to the user's chosen setup language. My problem is, that I can't figure out, how to get the user's language selection. I already tried to access the variables $LANGUAGE and $mui.LangDLL.RegistryLanguage, as well as trying to compare a defined language string to a specific translation string, but without success.

  • LinkedList parameters in Java

    Hi there, I created a program that contains linked lists that are passed various methods. While this works just fine in Java... a style checker program we have to use doesn't like it It says: Declaring variables, return values or parameters of type 'LinkedList' is not allowed. If I declare them as simply List then I don't have access to the methods I want. What should I do?

Right now I have hard coded these values,which apparently I should not be doing.
