  • Threading in client-server socket program - proxy sever

    - by crazyTechie
    I am trying to write a program that acts as a proxy server. Proxy server basically listens to a given port (7575) and sends the request to the server. As of now, I did not implement caching the response. The code looks like ServerSocket socket = new ServerSocket(7575); Socket clientSocket = socket.accept(); clientRequestHandler(clientSocket); I changed the above code as below: //calling the same clientRequestHandler method from inside another method. Socket clientSocket = socket.accept(); Thread serverThread = new Thread(new ConnectionHandler(client)); serverThread.start(); class ConnectionHandler implements Runnable { Socket clientSocket = null; ConnectionHandler(Socket client){ this.clientSocket = client; } @Override public void run () { try { PrxyServer.clientRequestHandler(clientSocket); } catch (Exception ex) { ex.printStackTrace(); } } } Using the code, I am able to open a webpage like google. However, if I open another web page even I completely receive the first response, I get connection reset by peer expection. 1. How can I handle this issue Can i use threading to handle different requests. Can someone give a reference where I look for example code that implements threading. Thanks. Thanks.

  • Writing a report

    - by wvd
    Hello all, Since some time I've been investigating more time into profiling things better, really think about how to do a thing and why. Now I'm going to start a new project, where I will be writing a report about. The report will be about anything what I wrote in the project, why, and I'll be investigating some things and do particular research about them. I've seen some reports, such as game programming in Haskell using FRP. However, after reading several reports they all seem to be build different. I have a few questions about writing a report: 1] What are the things I really should include, and what are the things I really shouldn't include? 2] Is it useful to include graphs about different methods/approaches to a several problem, where you only included one into your project, to show WHY you didn't include the other methods. Or should I just explain the method/approach used into the project. 3] Should I only be writing the report after I've completed the project, or should I also write pages about what I expect, how I'm going to build the software? Thanks, William van Doorn

  • I want a function to return a type of the subclass its invoked from

    - by Jay
    I want to have a function defined in a superclass that returns a value of the type of the subclass that is used to invoke the function. That is, say I have class A with a function plugh. Then I create subclasses B and C that extend A. I want B.plugh to return a B and C.plugh to return a C. Yes, they could return an A, but then the caller would have to either cast it to the right subtype, which is a pain when used a lot, or declare the receiving variable to be of the supertype, which loses type safety. So I was trying to do this with generics, writing something like this: class A<T extends A> { private T foo; public T getFoo() { return foo; } } class B extends A<B> { public void calcFoo() { foo=... whatever ... } } class C extends A<C> { public void calcFoo() { foo=... whatever ... } } This appears to work but it looks pretty ugly. For one thing, I get warnings on "class A". The compiler says that A is generic and I should specify the type. I guess it wants me to say "class A". But what would I put in for x? I think I could get stuck in an infinite loop here. It seems weird to write "class B extends A", but this causes no complaints, so maybe that's just fine. Is this the right way to do it? Is there a better way?

  • Custom progress bar label text via binding

    - by Alexander K
    I was playing with progress bar customization in Silverlight application. What I want to reach is to have progress bar label to show current its state in the following format: "Value / Maximum". So, user will see what is the current value, and what is the maximum possible value. Here is a style for progress bar I use: <Style x:Key="ProgressBarStyle" TargetType="ProgressBar"> <Setter Property="Width" Value="97.21" /> <Setter Property="Height" Value="19" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ProgressBar"> <Canvas x:Name="LevelField" Width="99" Height="21"> ... <TextBlock ... DataContext="{TemplateBinding Value}" Text="{Binding Converter={StaticResource DecNumberToStringConverter}}"/> </Canvas> </ControlTemplate> </Setter.Value> </Setter> </Style> The way I want to implement this, is to have a value converter, that will convert current value and maximum possible into the proper string. It does work properly, if it is written like above. However, I also need to provide ConverterParameter for Convertor, but not sure how to make it. When I write like this: , ConvertParameter={Binding Maximum}, it shows error on start, that Text attribute is not found in TextBlock. I was also trying to set DataContext as {RelativeSource Self}, but then it didn't displays error that DataContext attribute is not found. How to make the described progress bar label properly?

  • Exporting to CSV/Excel in Java

    - by WIOijwww
    I'm trying to export data into a CSV file through Java and I've got some code to do it but it doesn't seem to be outputting the CSV file. Could someone tell me what's wrong? What I would like to do is rather than saving the file somewhere, I would like it to be directly exported to the user. EDIT: Just in case it's not clear, I don't want the file to be saved anywhere but would like it to be outputted automatically to the user i.e. they click export and get the "Run/Save results.csv" window and they open the file. Currently the file is getting saved so I know that the method seems to work, just in the opposite way that I want it to. public static void writeToCSV(List<Map> objectList) { String CSV_SEPARATOR = ","; try { BufferedWriter bw = new BufferedWriter(new OutputStreamWriter( new FileOutputStream("results.csv"), "UTF-8")); for (Map objectDetails : objectList) { StringBuffer oneLine = new StringBuffer(); Iterator it = objectDetails.values().iterator(); while (it.hasNext()) { Object value = it.next(); if(value !=null){ oneLine.append(value.toString()); } if (it.hasNext()) { oneLine.append(CSV_SEPARATOR); } } bw.write(oneLine.toString()); bw.newLine(); } bw.flush(); bw.close(); } catch (UnsupportedEncodingException e) { } catch (FileNotFoundException e) { } catch (IOException e) { } }

  • How does an ASP.NET programmer go from working on/developing existing sites, to creating one from sc

    - by SLC
    I've been an ASP.NET developer for some time, always working on existing ASP.NET pages, modifying functionality, adding features, tweaking things etc. but have never built a site up from scratch. I've read books on ASP.NET, and they generally talk you through the various features of ASP.NET with a mock up site, but it's always very basic and they jump straight in. The time has come however, to write a site from scratch for a client. I've never done this before. There are design considerations, but like a lot of ASP.NET sites, the basic idea is, you have a site, where users can log in, and save some information like their name and password and address. The site has some functionality, but that's the basic design of a majority of (business-related) asp.net websites I would wager. I know how to program in ASP.NET already on an existing site, but I don't know how to design my own properly that meets the criteria above. I guess the main worry is security. I don't know the best way to handle a simple log-in system that stores user information like their name and password. I understand there are a few approaches to this, but the catch with this project is that it has to be absolutely bulletproof. Maximum security. All those good practices for security, it needs to have them all. I'm not asking what they are, but I am asking where to begin. What should be the first steps after I do File New Project ? Where can I look for information about setting up a secure ASP.NET website? I'll figure out the content and page layout later, it's the framework that is the big thing. Any and all advice would be welcome. I really want to get my first from-scratch project right from the beginning. Just to confuse things, it's possible I will be using MVC, I am not sure if this has any impact.

  • How to structure code with 2 methods, one after another, which throw the same two exceptions?

    - by dotnetdev
    Hi, I have two methods, one called straight after another, which both throw the exact same 2 exceptions (IF an erroneous condition occurs, not stating that I'm getting exceptions). For this, should I write seperate try and catch blocks with the one statement in each try block and catch both exceptions (Both of which I can handle as I checked MSDN class library reference and there is something I can do, eg, re-open SqlConnection or run a query and not a stored proc which does not exist). So code like this: try { obj.Open(); } catch (SqlException) { // Take action here. } catch (InvalidOperationException) { // Take action here. } And likewise for the other method I call straight after. This seems like a very messy way of coding. The other way is to code with the exception variable (that is ommited as I am using AOP to log the exception details, using a class-level attribute). Doing this, this could aid me in finding out which method caused an exception and then taking action accordingly. Is this the best approach or is there another best practise altogether? I also assume that, as only these two methods are thrown, I do not need to catch Exception as that would be for an exception I cannot handle (causes way out of my control). Thanks

  • SQL aggregate query question

    - by Phil
    Hi, Can anyone help me with a SQL query in Apache Derby SQL to get a "simple" count. Given a table ABC that looks like this... id a b c 1 1 1 1 2 1 1 2 3 2 1 3 4 2 1 1 ** 5 2 1 2 ** ** 6 2 2 1 ** 7 3 1 2 8 3 1 3 9 3 1 1 How can I write a query to get a count of how may distinct values of 'a' have both (b=1 and c=2) AND (b=2 and c=1) to get the correct result of 1. (the two rows marked match the criteria and both have a value of a=2, there is only 1 distinct value of a in this table that match the criteria) The tricky bit is that (b=1 and c=2) AND (b=2 and c=1) are obviously mutually exclusive when applied to a single row. .. so how do I apply that expression across multiple rows of distinct values for a? These queries are wrong but to illustrate what I'm trying to do... "SELECT DISTINCT COUNT(a) WHERE b=1 AND c=2 AND b=2 AND c=1 ..." .. (0) no go as mutually exclusive "SELECT DISTINCT COUNT(a) WHERE b=1 AND c=2 OR b=2 AND c=1 ..." .. (3) gets me the wrong result. SELECT COUNT(a) (CASE WHEN b=1 AND c=10 THEN 1 END) FROM ABC WHERE b=2 AND c=1 .. (0) no go as mutually exclusive Cheers, Phil.

  • Doing a virus check on a file from a build script

    - by the_mandrill
    I would like to be be able to invoke a virus check as the final stage of the build process (please don't question why a dev machine would get a virus, it's just a belt-and-braces approach to avoid the risk of getting sued by customers...). Also I'd like the option of having AV on a machine but switching the auto file system protection off (at least for the build directories). What I would like is a generic way of scanning a file using whatever AV system is in place. I'm assuming that there's an Windows API to do this, given that Windows detects the presence of an AV system, and browsers such as Firefox invoke a virus scan whenever a file is downloaded. So what's the API that they're using? There's the Microsoft AntiVirus API but that seems to be specific to Office documents. Does the approach involve using WMI? (and if you can detect the AV provider from there, how do you then invoke it to scan a file?) I know that I could write the script to manually call the AV scanner that I know to be installed, but as an intellectual exercise I'm more interested to know how apps like Firefox are doing this.

  • In this example where is the C++ assignment operator used rather than the copy constructor ?

    - by Bill Forster
    As part of an ongoing process of trying to upgrade my C++ skills, I am trying to break some old habits. My old school C programmer inclination is to write this; void func( Widget &ref ) { Widget w; // default constructor int i; for( i=0; i<10; i++ ) { w = ref; // assignment operator // do stuff that modifies w } } This works well. But I think the following is closer to best practice; void func( Widget &ref ) { for( int i=0; i<10; i++ ) { Widget w = ref; // ?? // do stuff that modifies w } } With my Widget class at least, this works fine. But I don't fully understand why. I have two theories; 1) The copy constructor runs 10 times. 2) The copy constructor runs once then the assignment operator runs 9 times. Both of these trouble me a little. 2) in particular seems artificial and wrong. Is there a third possibility that I am missing ?

  • Low Throughput on Windows Named Pipe Over WAN

    - by MichaelB76
    I'm having problems with low performance using a Windows named pipe. The throughput drops off rapidly as the network latency increases. There is a roughly linear relationship between messages sent per second and round trip time. It seems that the client must ack each message before the server will send the next one. This leads to very poor performance, I can only send 5 (~100 byte) messages per second over a link with an RTT of 200 ms. The pipe is asynchronous, using multiple overlapped write operations (and multiple overlapped reads at the client end), but this is not improving throughput. Is it possible to send messages in parallel over a named pipe? The pipe is created using PIPE_TYPE_MESSAGE, would PIPE_READMODE_BYTE work better? Is there any other way I can improve performance? This is a deployed solution, so I can't simply replace the pipe with a socket connection (I've read that Windows named pipe aren't recommended for use over a WAN, and I'm wondering if this is why). I'd be grateful for any help with this matter.

  • Problem with mathamatical calculation in JQUERY

    - by Param-Ganak
    Hello friends! I have two text boxes. I enter number in one textbox. I write following JQUERY for that textbox which get executed when the focus out from first text box. The JQUERY code takes the entered value from first text box and multiply it by a decimal number 34.95 and display the answer in second text box. The code is doing the calculation little bit ok because when I enter the value 1000 in first text box it gives answer 34950 in second textbox and when I enter the value 100 in first text box it gives answer 3495.0000000000005 in second text box. **Please any one tell me what is the problem. is problem is in my JQUERY code. I also want to show the answer always in decimal point. Answer should always dislply only two digits after decimal point. so How to achieve this too.** This is my JQUERY code. $("#id_pvalue").focusout(function() { q=$("#id_pvalue").val(); var ans=q*34.95; $("#id_tvalue").val(ans); }); Please guide me friends!

  • Can anyone provide a good "idiot's guide" to creating an installer in VS2008 (C#) Pro?

    - by paxdiablo
    I have Visual C# 2008 Professional and have developed the first half of a C# application (console mode) with the second half in progress now (GUI). I'm looking for an easy path to creating an installer for it. What are the steps that need to be taken to produce a professional installer? There's a similar question here regarding the Express edition but I have Pro, and I would like as much as possible to stick with just the standard VS stuff (if you think you can convince me that a third party installer creator is much better than a VS-only solution, give it a shot, by all means). Keep in mind that I have no interest in upgrading to VS2010 yet, even if it's a hundred times easier to create an installer. That can come later, when the revenue starts rolling in :-) Also be aware that the GUI component of this application is a totally separate executable from the console part. The console part is a simple "open file 1, do some work on it, write file 2" type and the GUI is a fairly standard "open file, do some stuff" beast so there's no tricky or wildly undocumented behaviour happening. Basically, I'm looking for (at least) the following: professional looking installer. ability to specify where the application files go. changes to the registry to allow double-clicks on my file extension to open the GUI app with the file as an argument. needs to install everything required (my stuff, .Net if required, and so on).

  • How do Oracle Forms compare to Microsoft Access as a "front-end"?

    - by webworm
    I recently started a project where I was set to build an ADP based application in Access 2003. The font end GUI was going to be in Access while all the data resided in MS SQL Server. I say "was", because the powers that be have decided that Oracle Forms might be a better choice than Access and SQL Server. The place where I am doing this work is an Oracle shop where they use Oracle 10g. They also use Oracle Forms quite a bit internally. As for me I am always up for learning anything new. I have always been a rather "eclectic" developer (I work with .NET WinForms, ASP.NET, Java, C#, Python, and Access) so I would not mind moving to Oracle Forms as long as it could do the same things as MS Access (hopefully even more as VBA is rather limited). So my question is this. How does Oracle Forms (10g) compare to MS Access for developing a GUI application? Access uses VBA for it's language, what does Oracle Forms use? I know the Forms app is a Java applet. Does that means you can write Oracle Forms using Java?

  • Generating HTML Programmatically in C#, Targeting Printed Reports

    - by John Passaniti
    I've taken over a C# (2.0) code base that has the ability to print information. The code to do this is insanely tedious. Elements are drawn onto each page, with magic constants representing positioning. I imagine the programmer sitting with a ruler, designing each page by measuring and typing in the positions. And yes, one could certainly come up with some nice abstractions to make this approach rational. But I am looking at a different method. The idea is that I'll replace the current code that prints with code that generates static HTML pages, saves them to a file, and then launches the web browser on that file. The most obvious benefit is that I don't have to deal with formatting-- I can let the web browser do that for me with tags and CSS. So what I am looking for is a very lightweight set of classes that I can use to help generate HTML. I don't need anything as heavyweight as HTMLTextWriter. What I'm looking for is something to avoid fragments like this: String.Format("<tr><td>{0}</td><td>{1}</td></tr>", foo, bar); And instead take have this kind of feel: ... table(). tr(). td(foo). td(bar) Or something like that. I've seen lightweight classes like that for other languages but can't find the equivalent (or better) for C#. I can certainly write it myself, but I'm a firm believer in not reinventing wheels. Know anything like this? Know anything better than this?

  • Using multiple Qt (SQL) Models

    - by radix07
    I have a near real-time application that I am using Qt and an SQLite database to run. I am curious if it is safe to have two separate models access a database at once. I know 2 separate views can access a model just fine, but I can't find any document addressing this. I also realize that SQLite is thread safe for reading, so I don't see a real issue to doing this from the SQLite part of things... Basically I want to use a QSqlTableModel to do the real-time read and write in the background and at the same time use a QSqlQueryModel to give the user desired data. Since I may be doing lots of filtering in the background using the table model I can't use it as the main view as well. I have gotten this to work for the most part, but am not sure if this is the best way to do this. If the models act like multiple SQL queries I don't believe this should be an issue, but I would like to know from someone I bit more knowledgeable about this stuff since this is pretty new to me. Thanks

    I have start and end dates which are stored in a database in this format: start date= 20121004 //4th October 2012 end date= 20121004 //16th November 2012 so I can use date format: $date = date("Ymd"); // returns: 20121004 to determine when to display and not display to repopulate my update input boxes I use: $start=(str_split($stdate,4));// START DATE: splits stored date into 2x4 ie: 20121209 = 2012 1209 $syr = $start[0];// re first half ie: 2012 which is the year $start2 = $start[1];//re second half ie: 1209 $start3=(str_split($start2,2));// splits second half date into 2x2 ie: 1209 = 12 09 $smth = $start3[0]; // first half = month ie: 12 $sday = $start3[1]; // second half = day ie: 09 $expiry=(str_split($exdate,4)); ///SAME AGAIN FOR EXPIRY DATE ... $xyr = $expiry[0]; $expiry2 = $expiry[1]; $expiry3=(str_split($expiry2,2)); $xmth = $expiry3[0]; $xday = $expiry3[1]; which works fine but I need to repopulate the input boxes for the month showing the date in the database like this <option value="01">January</option`> using if ($smth==01):$month='January'; endif; if ($xmth==01):$month='January'; endif; // if the start and/or expiry month number = 01 display $month as January if ($smth==02):$smonth='February'; endif; if ($xmth==02):$smonth='February'; endif; if ($smth==03):$month='March'; endif; <select name="stmonth" class="input"> <option value="<?=$smth?>"><?=$month?></option> ... </select> is there an easier way to display IF EITHER ONE EQUALS rather than having to write the same line twice once for each $smth AND $xmth ? re: if ($smth **and or** $xmth ==01):$month='January'; endif;

  • Is this use of PreparedStatements in a Thread in JAVA correct?

    - by Gormcito
    I'm still an undergrad just working part time and so I'm always trying to be aware of better ways to do things. Recently I had to write a program for work where the main thread of the program would spawn "task" threads (for each db "task" record) which would perform some operations and then update the record to say that it has finished. Therefore I needed a database connection object and PreparedStatement objects in or available to the ThreadedTask objects. This is roughly what I ended up writing, is creating a PreparedStatement object per thread a waste? I thought static PreparedStatments could create race conditions... Thread A stmt.setInt(); Thread B stmt.setInt(); Thread A stmt.execute(); Thread B stmt.execute(); A´s version never gets execed.. Is this thread safe? Is creating and destroying PreparedStatement objects that are always the same not a huge waste? public class ThreadedTask implements runnable { private final PreparedStatement taskCompleteStmt; public ThreadedTask() { //... taskCompleteStmt = Main.db.prepareStatement(...); } public run() { //... taskCompleteStmt.executeUpdate(); } } public class Main { public static final db = DriverManager.getConnection(...); }

  • Is there a free tool which can help visualize the logic of a stored procedure in SQL Server 2008 R2?

    - by Hamish Grubijan
    I would like to be able to plot a call graph of a stored procedure. I am not interested in every detail, and I am not concerned with dynamic SQL (although it would be cool to detect it and skip it maybe or mark it as such.) I would like the tool to generate a tree for me, given the server name, db name, stored proc name, a "call tree", which includes: Parent stored procedure. Every other stored procedure that is being called as a child of the caller. Every table that is being modified (updated or deleted from) as a child of the stored proc which does it. Hopefully it is clear what I am after; if not - please do ask. If there is not a tool that can do this, then I would like to try to write one myself. Python 2.6 is my language of choice, and I would like to use standard libraries as much as possible. Any suggestions? EDIT: For the purposes of bounty Warning: SQL syntax is COMPLEX. I need something that can parse all kinds of SQL 2008, even if it looks stupid. No corner cases barred :) EDIT2: I would be OK if all I am missing is graphics.
