  • Extract item in a list if Contains returns true

    - by Matt
    I have two lists A and B, at the beginning of my program, they are both filled with information from a database (List A = List B). My program runs, List A is used and modified, List B is left alone. After a while I reload List B with new information from the database, and then do a check with that against List A. foreach (CPlayer player in ListA) if (ListB.Contains(player)) ----- Firstly, the object player is created from a class, its main identifier is player.Name. If the Name is the same, but the other variables are different, would the .Contains still return true? Class CPlayer( public CPlayer (string name) _Name = name At the ---- I need to use the item from ListB that causes the .Contains to return true, how do I do that?

  • SAX Parse Exception

    - by Anand
    Hi, I am using JMS Messaging in my java program. My messages are coming from IBM Main Frame and the messages are xml files. Mainframe pushwa messages that is xml files to the queue But when the java program reads the messages from the queue an additional character "?" gets added in front of the xml file. For example a file like this: <?xml version="1.0" encoding="UTF-8"?> becomes ?<?xml version="1.0" encoding="UTF-8"?> when I read the message from the queue. And when I try to parse this I catch the following exception SAX Exception org.xml.sax.SAXParseException: Content is not allowed in trailing section. Content is not allowed in trailing section What could be the reason for this additional character getting added ?

  • Robustly killing Windows programs stuck reporting 'problems'

    - by grrussel
    I am looking for a means to kill a Windows exe program that, when being tested from a python script, crashes and presents a dialog to the user; as this program is invoked many times, and may crash repeatedly, this is not suitable. The problem dialog is the standard reporting of a Windows error: "Foo.exe has encountered a problem and needs to close. We are sorry for the inconvenience" and offers a Debug, Send Error Report, and Don't Send buttons. I am able to kill other forms of dialog resulting from crashes (e.g. a Debug build's assert failure dialog is OK.) I have tried taskkill.exe, pskill, and the terminate() function on the Popen object from the subprocess module that was used to invoke the .exe Has anyone encountered this specific issue, and found a resolution? I expect automating user input to select the window, and press the "Don't Send" button is one possible solution, but I would like something far simpler if possible

  • How do I execute a shell-command in background?

    - by Adobe
    Here's a simple defun to run a shell script: (defun bk-konsoles () "Calls: bk-konsoles.bash" (interactive) (shell-command (concat (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") (if (buffer-file-name) (file-name-directory (buffer-file-name))) " &") nil nil)) If I start a program with no ampersand - it start the script, but blocks emacs until I close the program, if I don't put ampersand it gives error: /home/boris/its/plts/goodies/bk-konsoles.bash /home/boris/scl/geekgeek/: exited abnormally with code 1. Edit: So now I'm using: (defun bk-konsoles () "Calls: bk-konsoles.bash" (interactive) (shell-command (concat (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") (if (buffer-file-name) (file-name-directory (buffer-file-name))) " & disown") nil nil) (kill-buffer "*Shell Command Output*")) Edit 2: Nope - doesn't work: (defun bk-konsoles () "Calls: bk-konsoles.bash" (interactive) (let ((curDir default-directory)) ;; (shell-command (concat "nohup " (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") curDir) nil nil) (shell-command (concat (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") curDir "& disown") nil nil) (kill-buffer "*Shell Command Output*"))) keeps emacs busy - either with disown, or nohup. Here's a script I'm running if it might be of help: bk-konsoles.bash

  • Socket Communication in C#- IP-Port

    - by Ahmet Altun
    I am testing my socket programs at home, in local network. Server and client programs are running on seperate machines. Server program socket is binded as: serverSocket.Bind(new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8999)); Client program (on the other computer) is connected as: clientSocket.Connect(IPAddress.Parse("192.168.2.3"), 8999); Why can Client not communicate with server? Do I need to make some firewall configuration or something like that? Or am I writing Server Ip incorrectly to the Client? (I got it from cmd-ipconfig of server)

  • MATLAB for kids?

    - by yuk
    My seven-years old expresses large interest in computers (well, who doesn't? :). Since I'm mostly program in MATLAB, I'm thinking why not to teach him MATLAB. We did a small project with him (he had to solve as many simple arithmetic problems as possible in a limited time) and he get pretty excited. I coded, he watched and then tested. He also likes to do create interesting graphics and simple animations. So, what's next? I would appreciate any ideas for interesting projects, games, graphics? What math concepts he has to understand to program in MATLAB? Or may be you would say it's too early and we should start with something like Logo, Scratch or Alice?

  • Get user-inputed file name from JFileChooser Save dialog box

    - by Anya
    This answer to this question may seem obvious, but I'm actually struggling with it quite a bit. I've searched through JFileChooser methods in the API, and I've looked at some of the questions already asked and answered here on stackoverflow. My question is this. In my program, I am to allow the user to type in a file name which I will then use to create a brand new file that I will write on. How do you get the text the user has entered in the textfield next to the label "Save As:" on the Save dialog box provided by JFileChooser? Is there a JFileChooser method that would allow me to get that user-inputed text? Or would I have to go through another class, or do something else to get that text? Thank you so much, to anyone who answers. It's very late for me now, and this program is due in a few hours (meaning I'll be having another sleepless night). Desperate may be too strong a word, but I'm something close enough.

  • fgets and strcmp [C]

    - by Blackbinary
    I'm trying to compare two strings. One stored in a file, the other retrieved from the user (stdin). Here is a sample program: int main() { char targetName[50]; fgets(targetName,50,stdin); char aName[] = "bob"; printf("%d",strcmp(aName,targetName)); return 0; } In this program, strcmp returns a value of -1 when the input is 'bob'. Why is this? I thought they should be equal. How can i get it so that they are?

  • sql server 2008 express one row write problem

    - by bojanskr
    Hi everyone, I have the most bizarre problem(at least it is bizarre to me) with MSSQL Server Express 2008. The problem is the following: On the development machine I use MS SQL Server 2008 Enterprise....I get some data from a WCF service and write that data to the db (simple as it can be)....I should point out however that the writing, it is done in a separate thread. BUt, anyway no problems during development...all the data is there. Then I set everything up(connection strings .\SQLEXPRESS, other settings) build in Release and copy that to a test machine that has MS SQL Server Express installed(because my application is a client application and it should work with Express)...I run the program....the program retrieves the data from the service...and when I look at the database...I'm in for a big suprise...there's only one row written(the first row received from the WCF service). I would really appreciate any help...I'm in a deadlock here. Thanks in advance. Bojan

  • Setting up gcov in Xcode 3.1

    - by Algorithmic
    I'm trying to setup my Xcode project to be instrumented with gcov so I can determine the code coverage of my unit tests. All of the documentation I find online talks about settings that I don't find in Xcode 3.1, though. An example: To work with Coverstory, first you need to set up your target to work with gcov. This requires turning on "Instrument Program Flow", "Generate Test Coverage Files" and linking with the gcov library. (Using Coverstory) The closest thing I can find to "Instrument Program Flow" and "Generate Test Coverage Files" in my build settings is "Generate Profiling Code", which doesn't appear to do what I want it to do. Am I looking in the wrong place for these settings or are all of the examples I'm finding online stale?

  • How to demonstrate java multithreading visibility problems?

    - by Joe23
    If variables in Java are accessed from multiple threads, one must ensure that they are safely published. This usually means using synchronizedor volatile. I have got the impression, that some of my colleagues do not take this issue seriously, since they "never heard of volatile before and their programs have worked for years". So my question is: Can someone provide an example Java program/snippet, that reliably shows data visibility problems. I think running a program and seeing the unexpected NPE or stale variable value would help more, than just theoretic explanations, that cannot be demonstrated. Thanks a lot for your help!

  • Java replace slow?

    - by cpf
    Hi StackOverflow, I have a Java application that makes heavy use of a large file, to read, process and give through to SolrEmbeddedServer (http://lucene.apache.org/solr/). One of the functions does basic HTML escaping: private String htmlEscape(String input) { return input.replace("&", "&amp;").replace(">", "&gt;").replace("<", "&lt;") .replace("'", "&apos;").replaceAll("\"", "&quot;"); } While profiling the application, the program spends roughly 58% of the time in this function, a total of 47% in replace, and 11% in replaceAll. Now, is the Java replace that slow, or am I on the right path and should I consider the program efficient enough to have its bottleneck in Java and not in my code? (Or am I replacing wrong?) Thanks in advance!

  • Pre-generating GUIDs for use in python?

    - by rjuiaa1
    I have a python program that needs to generate several guids and hand them back with some other data to a client over the network. It may be hit with a lot of requests in a short time period and I would like the latency to be as low as reasonably possible. Ideally, rather than generating new guids on the fly as the client waits for a response, I would rather be bulk-generating a list of guids in the background that is continually replenished so that I always have pre-generated ones ready to hand out. I am using the uuid module in python on linux. I understand that this is using the uuidd daemon to get uuids. Does uuidd already take care of pre-genreating uuids so that it always has some ready? From the documentation it appears that it does not. Is there some setting in python or with uuidd to get it to do this automatically? Is there a more elegant approach then manually creating a background thread in my program that maintains a list of uuids?

  • Demystifying gcc under lpthreads

    - by Berkay
    in these i'm playing with thread library and trying to implement some functions. One of the tutorial says that to run the program use : gcc -lpthread -lrt -lc -lm project1.c scheduler.c -o out first of all i need deep understanding of what is gcc doing in each line, lpthread is used for what? what are the contributions of lrt -lc -lm ? project1.c and scheduler.c is compiled together so what should i understand? i checked the code and any of them not included in project1.c or scheduler.c. as an output clearly it gives "out". secondly the author states that to run the program you have to use ./out number filename (For example, ./out 2 sample.txt) To make these clear as far as i understand the main function gets number and sample.txt as an input.(?) thanks for your answers and making me clear.

  • How long should it take a senior developer to solve FizzBuzz during an interview?

    - by Jim McKeeth
    Assuming: Typical interview stress levels (I am watching) Using familiar IDE and program language (their choice on their PC!) Given adequate explanation and immediate answers to questions Able to compile code and check answers / progress Claims to be a senior level programmer How long should it take an interviewee to answer FizzBuzz correctly? Edit: FizzBuzz: Write a program that prints the numbers from 1 to 100. But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz". Edit: It isn't so much that if they take more then X minutes they are disqualified, but I am curious if I should just cut them loose after they work on it for half hour.

  • Is there a faster alternative to using textures in XNA?

    - by Matthew Bowen
    I am writing a map editing program for a 2D game using XNA. To create a Texture2D for all of the tiles that a map requires takes too long. Are there any alternatives to using textures for drawing with XNA? I attempted to create just one texture per tile set instead of a texture for every tile in a tile set, but there is a limit to the size of textures and I could not fit all the tiles of a tile set into one texture. Currently the program contains all the would-be textures in memory as Bitmap objects. Is there a way to simply draw a Bitmap object to the screen in XNA? I have searched but I cannot find any information on this. This approach would avoid having to create textures altogether, however any tinting or effects I would have to do to the bitmap directly. Any help would be very much appreciated. Thanks

  • wxPython: Sending a signal to several widgets

    - by cool-RR
    I am not even sure how to ask this question. I want something that is like the wxPython event system, but a bit different. I'll try to explain. When there is a certain change in my program (a "tree change", never mind what that is,) I want to send a signal to all the widgets in my program, notifying them that a "tree change" has occurred, and they should change their display in response. How do I do this? It sounds a little bit like wxPython events, but not really, since events don't spread to all widgets, as far as I know. What would be a good way to do this?

  • deciding between subprocess, multiprocesser and thread in Python?

    - by user248237
    I'd like to parallelize my Python program so that it can make use of multiple processors on the machine that it runs on. My parallelization is very simple, in that all the parallel "threads" of the program are independent and write their output to separate files. I don't need the threads to exchange information but it is imperative that I know when the threads finish since some steps of my pipeline depend on their output. Portability is important, in that I'd like this to run on any Python version on Mac, Linux and Windows. Given these constraints, which is the most appropriate Python module for implementing this? I am tryign to decide between thread, subprocess and multiprocessing, which all seem to provide related functionality. Any thoughts on this? I'd like the simplest solution that's portable. Thanks.
