• asp.net global resources problem

  - by Bystrik Jurina

  Hello. I have a weird problem with global resources in my asp.net mvc web application. I have some resources in separate project(not a web app project). Those resources have following settings: Build action: Embedded Resource, Copy To Output Directory: Do not copy, Custom Tool: ResXFileCodeGenerator. When I change an existing value in resource file, build solution in release mode and upload neccesary dll files back to server, the previous values in resources are still shown. However, when I add a new key into resource file, the value of this key is shown properly. I do not have this problem during debugging on localhost. Thanks

• How to connect android application running on a device to a local web application?

  - by guna

  I have my droid device connected through USB and using Eclipse for debugging my application running on the device. Everything is fine, except my application needs to connect to a web application running on the same host computer (Windows XP, IE). The web address on the IE was "http://local:4566/MyApp/". I tried to set my android app to "http://10.0.2.2:4566/MyApp", but no luck. The android app's connection simply times out. The document under http://developer.android.com/guide/developing/tools/emulator.html says that the ip address may be different for devices (see Network Address Space section) but no further details on how to find that. Question is, how to I connect to a local web application running on my host computer (windows xp) from an Android application connected through USB running debug under Eclipse? Appreciate any help. thanks, Guna

• Hudson's FindBugs plugin reports line number "-1" for bugs. Ideas?

  - by John B.

  Greetings, I have a simple test project set up in Hudson and the project's build process (a batch file) generates a findbugs.xml file. This is processed by Hudson's FindBugs plugin but it shows the line number of the bugs as "-1" instead of their actual line number. A coworker suggested I enable debug info for the compiler. I used the -g "Generate all debugging info" option for javac but nothing seemed to change. My build command is: javac -g -classpath C:\testWebApp1\src -d C:\testWebApp1\build C:\testWebApp1\src\*.java The only other thing in the build.bat file is a call to the FindBug tool (text UI). Here is what the FindBugs Plugin says about the first bug: File: GenerateHellos.java, Line: -1, Type: UUF_UNUSED_FIELD, Priority: Normal, Category: PERFORMANCE Any ideas? Thanks a ton!

• Getting HTMLUnknownElement with jQuery.find() and an XML Document

  - by Tom

  I'm attempting to load up an XML document (specifically an RSS feed) via an Ajax request, parse it, and insert some information based on said feed into my page. The code works fine in Firefox, Opera, Chrome, and Safari, but not IE7. Go figure. After doing some initial debugging, I've found that the XML string is being retrieved via the request, and the specific node type I'm getting when trying to parse nodes out of the document is HTMLUnknownElement. Here's the relevant code: $.get('feed.php', function(oXmlDoc) { var titles = $(oXmlDoc).find('title'); var dates = $(oXmlDoc).find('pubDate'); for(var i = 0; i < 5; i++) { parseNodes(titles[i].firstChild.nodeValue, dates[i].firstChild.nodeValue)); } }); The parseNodes function is never actually being hit because IE cannot access firstChild and, consequently, nodeValue. Thanks in advance for any ideas and/or suggestions on how to address this.

• JavaScript - Multiple signals received after click

  - by Angelo A

  I'm creating a webapp using jQueryMobile. When I'm using the app and I click a button it runs the script multiple times. For example: I have a submit button: <input type="submit" id="login-normal" value="Login" /> And I have this JavaScript for debugging on which this error occurs: $("input#login-normal").live('click',function() { console.log("Test"); }); On the very first click it works (and it goes to another screen for example), but when I go back to that screen and I click again, it outputs multiple console.logs

• What could cause a returning function to crash? C++

  - by JeanOTF

  So I have been debugging this error for hours now. I writing a program using Ogre3d relevant only because it doesn't load symbols so it doesn't let me stack trace which made finding the location of the crash even harder. So, write before I call a specific function I print out "Starting" then I call the function and immediately after I print "Stopping". Throughout the function I print out letters A-F where F is printed right before the function returns (one line above the last '}') The weird thing is when the crash occurs it is after the 'F' is printed but there is no 'Stopping'. Does this mean that the crash is happening in between somewhere? The only thing I can think of is something going wrong during the deallocation of some of the memory allocated during the function. I've never had anything happen like this, I will keep checking to make sure it's going wrong where I think it is.

• ExpandEnvironmentStrings Not Expanding My Variables

  - by Adam Driscoll

  I have a process under the Run key in the registry. It is trying to access an environment variable that I have defined in a previous session. I'm using ExpandEnvironmentStrings to expand the variable within a path. The environment variable is a user profile variable. When I run my process on the command line it does not expand as well. If I call 'set' I can see the variable. Some code... CString strPath = "\\\\server\\%share%" TCHAR cOutputPath[32000]; DWORD result = ExpandEnvironmentStrings((LPSTR)&strPath, (LPSTR)&cOutputPath, _tcslen(strPath) + 1); if ( !result ) { int lastError = GetLastError(); pLog->Log(_T( "Failed to expand environment strings. GetLastError=%d"),1, lastError); } When debugging Output path is exactly the same as Path. No error code is returned. What is goin on?

• Reserved Memory Addresses?

  - by Nate

  Is there a list of reserved memory addresses out there - a list of addresses that the memory of a user-space program could never be allocated to? I realize this is most likely per-OS or per-architecture, but I was hoping someone might know some of the more common OSes and Arches. I could only dig one up for a few versions of windows: for windows NT,2k and XP that would be: 0x00000000 - 0x0000ffff - lowest page is protected to simplify debugging 0x00001000 - 0x7ffeffff - memory area for your application 0x7fff0000 - 0x7fffffff - protected area to keep memory-functions from damaging the following part 0x80000000 - 0xffffffff - memory where the system including drivers and so on is located Anyone know about for Linux, or BSD (or anything else, for that matter)?

• C++ Access variable value using string representing variable's name

  - by Paul Ridgway

  Hello everyone, If the title was not clear, I will try to clarify what I am asking: Imagine I have a variable called counter, I know I can see its current value by doing something like: std::cout << counter << std::endl; However, assume I have lots of variables and I don't know which I'm going to want to look at until runtime. Does anyone know a way I can fetch the value of a variable by using its name, for example: std::cout << valueOf("counter") << std::endl; I feel being able to do this might make debugging large complex projects easier. Thanks in advance for your time. PS: Please do not respond with 'Google it', I have, though maybe not with the best query to get the answer I'm looking for...

• Extracting fixture for one specific object

  - by emostar

  I want to extract the necessary code to recreate a set of Models from my production environment to my testing environment. There is something wrong in the data that causes an Exception, and I need the data in my local environment to do debugging. I looked at django-extensions and the dumpscript command is almost what I want. But I have many other objects connected to this one via foreign keys. Is there an easy way to extract the object by primary key, and all other objects that are related to it?

• Constantly getting ...DeviceMonitor] Failed to start monitoring

  - by makar

  I find that after running or debugging my application a few times using eclipse, that I get the above output in my console (in red) and I get no feedback from Dalvik as to the connection status to my phone is going. My application will still debug etc. I just get nothing useful in my Console. Any ideas how to fix this? It appears intermittent. It starts doing it after a few minutes, continues to do it for quite a while and occasionally goes away again. This has happened on my last laptop and now on my new laptop with a completely fresh install etc.

• Maintaining Logging and/or stdout/stderr in Python Daemon

  - by dave mankoff

  Every recipe that I've found for creating a daemon process in Python involves forking twice (for Unix) and then closing all open file descriptors. (See http://www.jejik.com/articles/2007/02/a_simple_unix_linux_daemon_in_python/ for an example). This is all simple enough but I seem to have an issue. On the production machine that I am setting up, my daemon is aborting - silently since all open file descriptors were closed. I am having a tricky time debugging the issue currently and am wondering what the proper way to catch and log these errors are. What is the right way to setup logging such that it continues to work after daemonizing? Do I just call logging.basicConfig() a second time after daemonizing? What's the right way to capture stdout and stderr? I am fuzzy on the details of why all the files are closed. Ideally, my main code could just call daemon_start(pid_file) and logging would continue to work.

• Why doesn't my viewmodel properties get populated

  - by Jakob

  Hi. I've looked all over and I can't figure out why my viewmodel doesn't get populated. I have this code: Followers = new ObservableCollection<aspnet_User>(_followersRepo.aspnet_Users); _followersRepo.Load(_followersRepo.GetUsersFollowingIDQuery(CurrentUserId)); Following = new ObservableCollection<aspnet_User>(_followingRepo.aspnet_Users); _followingRepo.Load(_followingRepo.GetUsersFollowedByIDQuery(CurrentUserId)); CurrentUser = _fullUserRepo.FullUsers.SingleOrDefault(); _fullUserRepo.Load(_fullUserRepo.GetFullUserByIDQuery(CurrentUserId)); But when I debug, there is no data loaded to the Followers, Following and CurrentUser objects. I know that data should be returned because I'm trying to implement the MVVM pattern in my app, and haven't changed the domainservice. Also I can se debugging the CurrentUserId has a value.

• How can I display more info in an error message when using NUnit Assert in a loop?

  - by Ian

  Consider the following code: [Test] public void WidgetTest() { foreach (Widget widget in widgets) { Assert.AreEqual(0, widget.SomeValue); } } If one of the asserts fails, I will get a very unhelpful error message like the one below: 1) Test Failure : WidgetTest.TestSomeValue Expected: 0 But was: 1 at WidgetTest.TestSomeValue() So, the question is, how can I get NUnit to display more useful info, such as the name of the widget, or the iteration of the loop, etc? Even a line number would be more helpful, since this is run in automated manner and I'd like to be able to spot the failing assert without debugging into the code.

• .NET web service call slower when performed asynchronously

  - by joelt

  I have an ASP.NET site, and some pages need to call a web service. I used Visual Studio's "Add Web Reference" to auto-generate classes and methods for the web service. When I call the service synchronously, i.e. objService.MethodName("param1"), a call might take a second or so. When I call it asynchronously, i.e., objService.BeginMethodName("param1", AddressOf MyCallback, Nothing), it typically takes about 6 seconds. When debugging, it appears that the bulk of the time is spent waiting between the completion of the BeginMethodName call and the beginning of MyCallback. Does the thread switching really incur that much overhead? Is there another reason for this?

• samsung galaxy tab 4 not recognized by eclipse

  - by michael

  the just released samsung galaxy tab 4 tablet does bring up the 'autoplay' box with device options when connected, but is not being recognized by eclipse, nothing shows in the device window. I have enabled debugging on the galaxy tab, including tapping the 'about' box 7 times to make the developer options magically appear. it runs kitkat and the Samsung site has a 'no data available' under the driver tab for this device. since it just came out at target last week it's unlikely there would be a new driver anyway, which has been the usual suggestion for this question on older models.

• /form making table go odd

  - by noryb009

  I have a table (3x3) that counts "< /form" as space in IE. The code for 1 td looks like: <style type="text/css"> table { border-width: 0px; border-collapse: collapse; padding: 0px; } td, th { padding: 0px; } </style> <table><tr><td><form name="form" action="index.php" method="post"><input type="hidden" name="from" value="a" /><input type="image" src="pic1.gif" alt="1" name="submit" value="submit" /></form></td> There is no spaces anywhere outside the tags. Inside the td, there is a form, with a hidden field and a picture. Firefox shows only the picture, but IE has spaces between the rows. I did a little debugging, and found it was from the /form. Does anyone know a fix to this?

• How to leave out some System.out/logging statements while executing java code?

  - by iamrohitbanga

  In C++ if we do not want some statements to compile into code that ships like assert function calls, we control their compilation through #ifndef preprocessor directives. How do we do this in Java? I have some System.out.println() statements for debugging which I would like to remove for the final code. one way is to make them execute conditionally under the affect of a boolean variable. Is there a better way of doing this? As I have a java swing application I can turn off the System.out.println statements without affecting the output. What is the method of doing this?

• Best practices to test protected methods with PHPUnit

  - by GrGr

  Hello, I found the discussion on Do you test private method informative. I have decided, that in some classes, I want to have protected methods, but test them. Some of these methods are static and short. Because most of the public methods make use of them, I will probably be able to safely remove the tests later. But for starting with a TDD approach and avoid debugging, I really want to test them. I thought of the following: Method Object as adviced in an answer seems to be overkill for this. Start with public methods and when code coverage is given by higher level tests, turn them protected and remove the tests. Inherit a class with a testable interface making protected methods public Which is best practice? Is there anything else? It seems, that JUnit automatically changes protected methods to be public, but I did not have a deeper look at it. PHP does not allow this via reflection.

• Windows service only gets called when Visual Studio is attached to process

  - by 64th

  I've created a simple windows service in C# using Visual Studio 2010. It uses a TcpListener and socket to listen for messages on a given port. This worked absolutely perfectly when my laptop had Windows Vista on it. However, since upgrading to Windows 7 and re-installing my service it only responds if I'm attached to the process and debugging in Visual Studio 2010 - at which time it behaves as expected. I've tried running the service under my (administrator) credentials and setting the exe to run as administrator. I've also checked "Allow service to interact with desktop" when it was running under the Local System account. I'm testing using both a test console app and an Adobe Air application - both with the same results. Are there some specific permissions that I need to allow the service to be called?

• C# Console Application - Odd behaviour - char '\a'

  - by KHT

  After extensive debugging of an application, I noticed the console window would hang when searching text for the char '\a'. The goal is to strip out characters from a file. The console window would always hang upon exiting the program, and it would make it to the last statement of main. I removed the '\a' from the switch statement and the console application does not hang anymore. Any idea why? I still need to strip out the char '\a', but cannot get the application to work without hanging. switch (c) { case '\t': //Horizontal Tab case '\v': //Vertical Tab case '\n': //Newline case '\f': //Form feed case '\r': //carriage return case '\b': //Backspace case '\x7f': //delete character case '\x99': //TM Trademark case '\a': //Bell Alert **REMOVED THIS** return true; }

• How do I build two different installers from the same script in inno?

  - by Tim

  I want to make a "standard" install for external use, but I also want to use the same script and tell it (with a command line param perhaps?) to include another set of files (PDB files for debugging) for our lab installations. How can I do this? Is it possible? I don't see how to set this in the [files] section. NOTE - this is not for having an option during the install. It is for static build time. I suppose it is just best to create a separate installer for the pdbs.

• Double # showing 0 on android

  - by Dave

  I'm embarrassed to ask this question, but after 45 minutes of not finding a solution I will resort to public humiliation. I have a number that is being divided by another number and I'm storing that number in a double variable. The numbers are randomly generated, but debugging the app shows that both numbers are in fact being generated. Lets just say the numbers are 476 & 733. I then take the numbers and divide them to get the percentage 476/733 = .64 I then print out the variable and it's always set to 0. I've tried using DecimalFormat and NumberFormat. No matter what I try though it always says the variable is 0. I know there is something simple that I'm missing, I just can't find it =/.

• How can I tell what is using the memory when there is a heap overflow in Java?

  - by Grae

  Hi all, I know a little about profiling, but what I am particularlly insterest in, is what has all the memory when I get these heap over flow exceptions. I will start getting them after about a hour of debugging. I am hoping there is some sort of dump or something, that I can use to get a list of what instances are around at the time the program starts. By the way, sorry if this is a lazy question. I really shoud put sometime in learning about profiling. Grae
