• Java convert JSONObject to URL parameter

  - by Alex Ivasyuv

  What is the elegant way to convert JSONObject to URL parameters. For example, JSONObject: {stat: {123456: {x: 1, y: 2}, 123457: {z: 5, y: 2}}}} this should be like: stat[123456][x]=1&stat[123456][y]=2&stat[123457][z]=5&stat[123457][y]=2 of course with escaped symbols, and of course JSON object could be more complicated.. Maybe there already exist some mechanisms for that? Thanks,

• What's the best way to tell if a file exists in a directory?

  - by Nano HE

  I'm trying to move a file but I want to ensure that it exists before I do so. What's the simplest way to do this in Perl? My code is like this. I looked up the open command, but I am not sure it is the simplest way or not. if #Parser.exe exist in directory of Debug { move ("bin/Debug/Parser.exe","Parser.exe"); } elsif #Parser.exe exist in directory of Release { move ("bin/Release/Parser.exe","Parser.exe"); } else { die "Can't find the Parser.exe."; } Thank you.

• Where did my Visual Studio exception assistant go?

  - by Steven

  Since a couple of weeks the Visual Studio (2008 9.0.30729.1 SP) Exception Assistant has stopt appearing while debugging using the C# IDE. Instead the old ugly and useless debug dialog comes up: To make sure, I've checked the following: "Tools / Options / Debugging / General / Enable the exception assistant" is on. "Debug / Exceptions / Common Language Runtime Exceptions / Thrown" is on. I reset my Visual Studio Settings. I googled. I checked all relevant stackoverflow questions. How can I get the Exception Assistant back? Who gives me the golden tip?

• Print stacktrace from C code with embedded lua

  - by Matt H

  If I understand this correctly, Lua by default will call the debug library "debug.traceback" when an error occurs. However, when embedding Lua into C code like done in the example here: Simple Lua API Example We only have available the error message on the top of the stack. i.e. if (status) { /* If something went wrong, error message is at the top of */ /* the stack */ fprintf(stderr, "Couldn't load file: %s\n", lua_tostring(L, -1)); /* I want to print a stacktrace here. How do I do that? */ exit(1); } How do I print the stack trace from C after the initial error?

• CakePHP: Ajax view problem (nothing in the view showing)

  - by Adim

  I created a function in my controller called addToPlaylist($songName). I wanted to add these song names to an array and then a session variable using an Ajax call. The first time i did this i got an error saying i do not have a template file to display in the chosen div ("add_to_playlist.ctp was missing"). I created this file and everything seemed to be working correctly. Basically I went to bed woke up and it is broken (it is possible I changed something before I went to bed). The problem now is that it does not show anything when i click the ajax link. when i click on the ajax link it seems to call the function but nothing displays in the view (except debug info) even when i delete the view (add_to_playlist.ctp) i get no errors, I just see debug info now.

• Killing a script launched in a Process via os.system()

  - by L.J.

  I have a python script which launches several processes. Each process basically just calls a shell script: from multiprocessing import Process import os import logging def thread_method(n = 4): global logger command = "~/Scripts/run.sh " + str(n) + " >> /var/log/mylog.log" if (debug): logger.debug(command) os.system(command) I launch several of these threads, which are meant to run in the background. I want to have a timeout on these threads, such that if it exceeds the timeout, they are killed: t = [] for x in range(10): try: t.append(Process(target=thread_method, args=(x,) ) ) t[-1].start() except Exception as e: logger.error("Error: unable to start thread") logger.error("Error message: " + str(e)) logger.info("Waiting up to 60 seconds to allow threads to finish") t[0].join(60) for n in range(len(t)): if t[n].is_alive(): logger.info(str(n) + " is still alive after 60 seconds, forcibly terminating") t[n].terminate() The problem is that calling terminate() on the process threads isn't killing the launched run.sh script - it continues running in the background until I either force kill it from the command line, or it finishes internally. Is there a way to have terminate also kill the subshell created by os.system()?

• GCC compiling a dll with __stdcall

  - by Chad

  When we compile a dll using __stdcall inside visual studio 2008 the compiled function names inside the dll are. FunctionName Though when we compile the same dll using GCC using wx-dev-cpp GCC appends the number of paramers the function has, so the name of the function using Dependency walker looks like. FunctionName@numberOfParameters or == FunctionName@8 How do you tell GCC compiler to remove @nn from exported symbols in the dll?

• How to mark a method as "ignore all handled exception" + "step through"? Even when user has selected

  - by Wolf5

  I want to mark a method as "debug step through" even if an exception is thrown (and catched within) the function. This is because 99% of the times I know this function will throw an exception (Assembly.GetTypes), and since this function is in a library I wish to hide this normal exception. (Why did MS not add an exceptionless GetTypes() call?) I have tried this but it still breaks the code when debugging: [DebuggerStepThrough] [DebuggerStepperBoundary] private Type[] GetTypesIgnoreMissing(Assembly ass) { Type[] typs; try { typs = ass.GetTypes(); } catch (ReflectionTypeLoadException ex) { typs = ex.Types; } var newlist = new List<Type>(); foreach (var type in typs) { if (type != null) newlist.Add(type); } return newlist.ToArray(); } Anyone know of a way to make this method 100% stepthrough even if ass.GetTypes() throw an exception in debug mode? It has to step through even when "Break on Thrown exceptions" is on. (I do not need to know I can explicitly choose to ignore that exact type of exception in the IDE)

• Tracing or Logging Resource Governor classification function behavior in Sql Server 2008

  - by nganju

  I'm trying to use the Resource Governor in SQL Server 2008 but I find it hard to debug the classification function and figure out what the input variables will have, i.e. does SUSER_NAME() contain the domain name? What does the APP_NAME() string look like? It's also hard to verify that it's working correctly. What group did the function return? The only way I can see this is to fire up the performance monitor and watch unblinkingly for little blips in the right CPU counter. Is there some way I can either run it in Debug mode, where I can set a breakpoint and step through and look at variable values, or can I at least do the old-school method of writing trace statements to a file so I can see what's going on? Thanks...

• Auto wiring of Property does not work for me

  - by Xabatcha

  Hi All, In my Asp.Net project I wanna use Property Auto-wiring, e.g. for my ILogger. Basically I placed Property into my base classes. One for Page, one for UserControl. Like below. public class UserControlBase : UserControl { public ILogger CLogger { get; set; } .... } However when calling in inherited control, logger is null. I checked the container and it'a definitely set. Below is setting which is called from Global.asax. public static void SetupForIoC() { Debug.WriteLine("SetupForIoC"); ObjectFactory.Initialize(x => { x.FillAllPropertiesOfType<ILogger>().TheDefaultIsConcreteType<EntLibLogger>().AsSingletons(); x.FillAllPropertiesOfType<ISiteService>().TheDefaultIsConcreteType<SiteService>().AsSingletons(); }); Debug.WriteLine(ObjectFactory.WhatDoIHave()); } Thanks for any advice, tip?

• Reset UIKeyboard State

  - by kamziro

  I have a UITextView which the keyboard enters values into. However, if you clear the text value (i.e uitextview.text = @""), the keyboard's state does not reset to the lowercase alphabet keyboard. That is, if I was in the middle of typing "hello.." and the textview gets cleared, the keyboard still shows the symbols, rather than back to the alphabetical letters. Is there a way to get around this?

• Get variable name as string in Perl

  - by Jose Cuervo

  Hi, I am trying to get a text representation of a variable's name. For instance, this would be the function I am looking for: $abc = '123'; $var_name = &get_var_name($abc); #returns '$abc' I want this because I am trying to write a debug function that recursively outputs the contents of a passed variable, I want it to output the variable's name before hand so if I call this debug function 100 times in succession there will be no confusion as to which variable I am looking at in the output. I have heard of Data::Dumper and am not a fan. If someone can tell me how to if it's possible get a string of a variable's name, that would be great. Thanks!

• Drupal 6 devel module dd() function not writing to drupal_debug.txt file

  - by Mike Munroe

  I am running a local development Drupal site on a Windows machine. I am trying to use the dd($data, $label = NULL) function from the devel module to help debug. Using this function, should write debug info to a drupal_debug.txt file in the /tmp folder on the machine where the Drupal site is hosted. On my Windows machine, although I am using this function, the drupal_debug.txt file is not getting created anywhere, leading me to believe I am using the function incorrectly. Here is a snippet of how I am using it, <?php $test = "this is my test"; dd($test, $label = NULL); I am looking for an example of the correct syntax for the dd($data, $label = NULL) function. I have the Devel module enabled.

• Process.WaitForExit not triggering with __debugbreak

  - by Cypher2100

  I'm trying to write a program to test student code against a good implementation. I have a C++ console app that will run one test at a time determined by the command line args and a C# .net forms app that calls the c++ app once for each test. The goal is to be able to detect not just pass/fail for each test, but also "infinite" (5secs) loop and exceptions (their code dying for whatever reason). The problem is that not all errors kill the C++ app. If they corrupt the heap the system calls __debugbreak which pops up a window saying Debug Error! HEAP CORRUPTION DETECTED... My C# app is using Process.WaitForExit(5000) to wait, but this error doesn't count as an exit, so I see a timeout. So my question is, how can I either get the C# app to detect that this is an error OR how can I get the C++ app to die when this error occurs rather than giving a dialog box and asking if I want to debug?

• Why is visual studio not aware that an integer's value is changing? (debugging)

  - by incrediman

  I have a few simple lines of code (below). [bp] indicates a breakpoint. for(int i=0;i<300;i++){} int i=0; cout<<i; [bp] for (i=0;i<200;i++){} When I debug this in visual studio, it tells me that i is equal to 300 on the breakpoint. Annoyingly, 0 is printed to the console. Is there any way to make it realize that two variables in different scopes can actually have the same name? I also want to add some code to the second loop and then debug it - but when I try to do that, i is consistently shown as 300. Very annoying.
