  • Parsing C#, finding methods and putting try/catch to all methods

    - by erdogany
    I know it sounds weird but I am required to put a wrapping try catch block to every method to catch all exceptions. We have thousands of methods and I need to do it in an automated way. What do you suggest? I am planning to parse all cs files and detect methods and insert a try catch block with an application. Can you suggest me any parser that I can easily use? or anything that will help me... every method has its unique number like 5006 public static LogEntry Authenticate(....) { LogEntry logEntry = null; try { .... return logEntry; } catch (CompanyException) { throw; } catch (Exception ex) { logEntry = new LogEntry( "5006", RC.GetString("5006"), EventLogEntryType.Error, LogEntryCategory.Foo); throw new CompanyException(logEntry, ex); } } I created this for this; http://thinkoutofthenet.com/index.php/2009/01/12/batch-code-method-manipulation/

  • Help with SQL query (add 5% to users with conditions)

    - by Mestika
    Hi everyone, I’m having some difficulties with a query which purpose is to give users with more than one thread (called CS) in current year a 5% point “raise”. My relational schema looks like this: Thread = (threadid, threadname, threadLocation) threadoffering = (threadid, season, year, user) user = (name, points) Then, what I need is to check: WHERE thread.threadid = threadoffering.threadid AND where threadoffering.year AND threadoffering.season = currentDate AND where threadoffering.User 1 GIVE 5 % raise TO user.points I hope it is explained thoroughly but otherwise here it is in short text: Give a 5 % “point raise” to all users who has more than 1 thread in threadLocation CS in the current year and season (always dynamic, so for example now is year = 2010 and season is = spring). I am looking forward to your answer Sincerely, Emil

  • ansi-c fscanf problem

    - by mongoose
    hi i read the file as follows fscanf(fp,"%f %f %f",&*(p1+i), &*(p2+i), &*(p3+i)); my file's lines consists of three floating point numbers... the problem i have is that in the file let's say i have some floating points with let's say maximum of two digits after the dot. but when i ask c to print those values using different formatting, for example %lf,%.2lf,%.4lf... it starts to play with the digits... my only concern is this, if i have let's say 1343.23 in the file, then will c use this value exactly as it is in computations or it will play with the digits after the dot. if it will play, then how is it possible to make it so that it uses floating point numbers exactly as they are? for example in last case even if i ask it to print that value using %.10lf i would expect it to print only 1343.2300000000.? thanks a lot!

  • Storing and comparing biometric information

    - by Chathuranga Chandrasekara
    I am not sure whether this is the best place to post this. But this is strongly related with programming so decided to put this here. In general we use biometrics in computer applications say for authentication. Lets get 2 examples finger prints and facial recognition. In those cases how we keep the information for comparison. As an example we can't keep a image and process it every time. So what are the methodologies we use to store/determine the similarity in such cases? Are there any special algorithms that designed for that purposes.? (Ex : To return a approximately equal value for a finger print of a certain person every time)

  • Installing Daemons

    - by Shahmir Javaid
    Dear Stackoverflowers, A simple link would be nice for me to understand how to install my C++ program as a deamon in UNIX, now i know some will say this should be on SERVERFAULT but as far as i understand it i need the init.d shell script to actually create the start and stop for the daemons. But if you guys can show me a simple shell script for the daemon and the file directories every thing required is associated with, that would be great. I was going to do this http://www.linux.com/archive/feed/46892 but if you read the comments every one is moaning x( . P.S. ive already done the required code for C++ to run as a daemon i just need to know how to actually install it as a daemon. At the moment im using crontab which is just not a good idea for the future of my problem. Thanks in advance

  • xcode build to iphone chooses old invalid provisioning profile

    - by sapatos
    I've just gone through some pain with iphone and xcode upgrades and keychain failures etc and decided to uninstall xcode completely and re-install. This fixed my keychain issues however the project I am working on appears to be linked to an old invalid provisioning profile. I've deleted the profile from "Provisioning Profiles" in organiser, and removed it from Provisioning on the Iphone section of Organiser. However when I build an go with the iphone sdk rather than simulator i get the pop up "codesign wants to sign using key "OldKey" in your keychain". It appears the actual app is associated with the old key and I can't seem to find how to point it to the new valid one. Crazy thing is at some point I managed to get it to work and install but the application crashed and won't open. I've not managed to get it to install again. Any ideas?

  • Removing the obstacle that yields the best path from a map after A* traversal

    - by David Titarenco
    I traverse a 16x16 maze using my own A* implementation. This is exactly what my program does: http://www.screenjelly.com/watch/fDQh98zMP0c?showTab=share All is well. However, after the traversal, I would like to find out what wall would give me the best alternative path. Apart from removing every block and re-running A* on the maze, what's a clever solution? I was thinking give every wall node (ignored by A*), a tentative F-value, and change the node structure to also have a n-sized list of node *tentative_parent where n is the number of walls in the maze. Could this be viable?

That i would just need to edit home.js to change what other js (jquery etc) are loaded for home.htm ... home.htm would just point to home.js Thanks

  • Why is AudioOutputUnitStart freezing my app in iOS 4?

    - by Luke
    Hi guys, I have an audio app which uses the RemoteIO AudioUnit. It works fine on iPhone, iPad, and any flavor of the simulator on 3.2, but when it hits AudioOutputUnitStart (), it freezes. I get the message "AddRunningClient starting device on non-zero client count" in the console, which I'm not sure how to resolve. I stop the unit and dispose of the AudioComponent every time the app closes. The app works fine the first time I run after restarting everything, but freezes every time after that. What's strange is there are no error messages - just an unresponsive interface and a frozen line of code. Thanks for your help. Luke

  • Rails & ActiveRecord: Appending methods to models that inherit from ActiveRecord::Base

    - by PlankTon
    I have a standard ActiveRecord model with the following: class MyModel < ActiveRecord::Base custom_method :first_field, :second_field end At the moment, that custom_method is picked up by a module sent to ActiveRecord::Base. The functionality basically works, but of course, it attaches itself to every model class, not just MyModel. So if I have MyModel and MyOtherModel in the same action, it'll assume MyOtherModel has custom_method :first_field, :second_field as well. So, my question is: How do I attach a method (eg: def custom_method(*args)) to every class that inherits from ActiveRecord::Base, but not by attaching it to ActiveRecord::Base itself? Any ideas appreciated.

  • Linq to SQL DataContext Windsor IoC memory leak problem

    - by Mr. Flibble
    I have an ASP.NET MVC app that creates a Linq2SQL datacontext on a per-web-request basis using Castler Windsor IoC. For some reason that I do not fully understand, every time a new datacontext is created (on every web request) about 8k of memory is taken up and not released - which inevitably causes an OutOfMemory exception. If I force garbage collection the memory is released OK. My datacontext class is very simple: public class DataContextAccessor : IDataContextAccessor { private readonly DataContext dataContext; public DataContextAccessor(string connectionString) { dataContext = new DataContext(connectionString); } public DataContext DataContext { get { return dataContext; } } } The Windsor IoC webconfig to instantiate this looks like so: <component id="DataContextAccessor" service="DomainModel.Repositories.IDataContextAccessor, DomainModel" type="DomainModel.Repositories.DataContextAccessor, DomainModel" lifestyle="PerWebRequest"> <parameters> <connectionString> ... </connectionString> </parameters> </component> Does anyone know what the problem is, and how to fix it?

  • Java: how to register a listener that listen to a JFrame movement

    - by cocotwo
    How can you track the movement of a JFrame itself? I'd like to register a listener that would be called back every single time JFrame.getLocation() is going to return a new value. Here's a skeleton that compiles and runs, what kind of listener should I add so that I can track every JFrame movement on screen? import javax.swing.*; public class SO { public static void main( String[] args ) throws Exception { SwingUtilities.invokeAndWait( new Runnable() { public void run() { final JFrame jf = new JFrame(); final JPanel jp = new JPanel(); final JLabel jl = new JLabel(); updateText( jf, jl ); jp.add( jl ); jf.add( jp ); jf.pack(); jf.setVisible( true ); } } ); } private static void updateText( final JFrame jf, final JLabel jl ) { jl.setText( "JFrame is located at: " + jf.getLocation() ); jl.repaint(); } }

  • Limiting landscape views in UITabBarController containing UINavigationController

    - by Spider-Paddy
    I have a tab bar application that contains navigation views in 2 of its tabs. I would like 1 view in the 1 navigation controller to allow landscape view but because of the nav bar in tab bar limitation I now have to allow landscape views for every single view in my app to make the tilt messages get passed to my app which I don't want. I thought perhaps, on the views which shouldn't go to landscape, that there might be ways to either: prevent the view change e.g. calling setOrientation:UIDeviceOrientationPortrait whenever the device goes landscape or giving the illusion that the view doesn't change e.g. presenting a modal portrait view over the rotated view Anybody have any ideas or experience that they care to share? What is the best approach here? (I don't want to now have to design a landscape view for every view just to so that I can display a portrait & landscape view for 1 view)

  • Filtering MySQL query result according to a interval of timestamp

    - by celalo
    Let's say I have a very large MySQL table with a timestamp field. So I want to filter out some of the results not to have too many rows because I am going to print them. Let's say the timestamps are increasing as the number of rows increase and they are like every one minute on average. (Does not necessarily to be exactly once every minute, ex: 2010-06-07 03:55:14, 2010-06-07 03:56:23, 2010-06-07 03:57:01, 2010-06-07 03:57:51, 2010-06-07 03:59:21 ...) As I mentioned earlier I want to filter out some of the records, I do not have specific rule to do that, but I was thinking to filter out the rows according to the timestamp interval. After I achieve filtering I want to have a result set which has a certain amount of minutes between timestamps on average (ex: 2010-06-07 03:20:14, 2010-06-07 03:29:23, 2010-06-07 03:38:01, 2010-06-07 03:49:51, 2010-06-07 03:59:21 ...) Last but not least, the operation should not take incredible amount of time, I need this functionality to be almost fast as a normal select operation. Do you have any suggestions?

  • Using ptrace to generate a stack dump

    - by Gomez
    Hello. I am compiling C++ on *nix and I would like to generate a stack dump a) at an arbitrary point in the program, b) during any signal, particularly during SIGSEGV. Google tells me that ptrace is probably the tool for the job, but I can't find any comprehensible examples of walking the stack. Getting the return address, yeah, but what about the NEXT return address? And what about extracting the symbolic name of the function at that point? Something to do with DWARF? Many thanks if you can tell me where to go from here.

  • Can compiler optimization introduce bugs ?

    - by ereOn
    Hi, Today I had a discussion with a friend of mine and we debated for a couple of hours about "compiler optimization". I defended the point that sometimes, a compiler optimization might introduce bugs or at least, undesired behavior. My friend totally disagreed, saying that "compiler are built by smart people and do smart things" and thus, can never go wrong. He didn't convinced my at all, but I have to admit I lack of real-life examples to strengthen my point. Who is right here ? If I am, do you have any real-life example where a compiler optimization produced a bug in the resulting software ? If I'm mistaking, should I stop programming and learn fishing instead ? Thank you !

When it is time to deploy the application i just run package on the war project and my war is created with all the dependencies. Now there is a problem. One of the my module have heavy changes. Now when i created war for my projects these changes was not reflected in the output war file(the jar in lib folder of war has still the old code). Can you please point the things i am missing from the release process? Why the old code is being packaged with the war? Can you please point some good resource for real file build process using maven? Regards, Vijay

  • VBA/SQL recordsets

    - by intruesiive
    The project I'm asking about is for sending an email to teachers asking what books they're using for the classes they're teaching next semester, so that the books can be ordered. I have a query that compares the course number of this upcoming semester's classes to the course numbers of historical textbook orders, pulling out only those classes that are being taught this semester. That's where I get lost. I have a table that contains the following: -Professor -Course Number -Year -Book -Title The data looks like this: professor year course number title smith 13 1111 Pride and Prejudice smith 13 1111 The Fountainhead smith 13 1222 The Alchemist smith 12 1111 Pride and Prejudice smith 11 1222 Infinite Jest smith 10 1333 The Bible smith 13 1333 The Bible smith 12 1222 The Alchemist smith 10 1111 Moby Dick johnson 12 1222 The Tipping Point johnson 11 1333 Anna Kerenina johnson 10 1333 Everything is Illuminated johnson 12 1222 The Savage Detectives johnson 11 1333 In Search of Lost Time johnson 10 1333 Great Expectations johnson 9 1222 Proust on the Shore Here's what I need the code to do "on paper": Group the records by professor. Determine every unique course number in that group, and group records by course number. For each unique course number, determine the highest year associated. Then spit out every record with that professor+course number+year combination. With the sample data, the results would be: professor year course number title smith 13 1111 Pride and Prejudice smith 13 1111 The Fountainhead smith 13 1222 The Alchemist smith 13 1333 The Bible johnson 12 1222 The Tipping Point johnson 11 1333 Anna Kerenina johnson 12 1222 The Savage Detectives johnson 11 1333 In Search of Lost Time I'm thinking I should make a record set for each teacher, and within that, another record set for each course number. Within the course number record set, I need the system to determine what the highest year number is - maybe store that in a variable? Then pull out every associated record so that if the teacher ordered 3 books the last time they taught that class (whether it was in 2013 or 2012 and so on) all three books display. I'm not sure I'm thinking of record sets in the right way, though. My SQL so far is basic and clearly doesn't work: SELECT [All].Professor, [All].Course, Max([All].Year) FROM [All] GROUP BY [All].Professor, [All].Course; Thanks for your help.

  • Scrolling when idle?

    - by Julie
    Can anyone point me to an example of code for a page that begins to automatically scroll when the user is idle for an amount of time? I think this is slightly beyond my skill set. I think JQuery or something similar might be appropriate but I just can't seem to figure it out. I'm designing a site for the nonprofit I work for and we don't have the money to hire a programmer. I wouldn't ask anyone to code anything for me, just to point me in the right direction. Thank you so much. Julie K.

  • How can I hot deploy using the glassfish adapter in Eclipse

    - by Greg
    Has anyone gotten the glassfish v3 adapter to work with Eclipse without restarting every time there's a code change? I tried to set this up but the adapter "republishes" every time I change any file, which is very annoying. It takes up to 3 minutes and locks up my machine for a second. I must remember to constantly stop the adapter before making any changes. I'd settle for just disabling this "feature", but even if I uncheck "publish change immediately" this behavior still happens. I'm using the latest version of the glassfish adapter and tried with eclipse 3.5 and the 3.6 milestone builds.... What setup is everyone using if you have glassfish v3 as your server? Is there any way to actually get the hot deploy feature to work correctly?

  • serving large file using select, epoll or kqueue

    Nginx uses epoll, or other multiplexing techniques(select) for its handling multiple clients, i.e it does not spawn a new thread for every request unlike apache. I tried to replicate the same in my own test program using select. I could accept connections from multiple client by creating a non-blocking socket and using select to decide which client to serve. My program would simply echo their data back to them .It works fine for small data transfers (some bytes per client) The problem occurs when I need to send a large file over a connection to the client. Since i have only one thread to serve all client till the time I am finished reading the file and writing it over to the socket i cannot resume serving other client. Is there a known solution to this problem, or is it best to create a thread for every such request ?
