  • Background worker not working right

    - by vbNewbie
    I have created a background worker to go and run a pretty long task that includes creating more threads which will read from a file of urls and crawl each. I tried following it through debugging and found that the background process ends prematurely for no apparent reason. Is there something wrong in the logic of my code that is causing this. I will try and paste as much as possible to make sense. While Not myreader.EndOfData Try currentRow = myreader.ReadFields() Dim currentField As String For Each currentField In currentRow itemCount = itemCount + 1 searchItem = currentField generateSearchFromFile(currentField) processQuerySearch() Next Catch ex As Microsoft.VisualBasic.FileIO.MalformedLineException Console.WriteLine(ex.Message.ToString) End Try End While This first bit of code is the loop to input from file and this is what the background worker does. The next bit of code is where the background worker creates threads to work all the 'landingPages'. After about 10 threads are created the background worker exits this sub and skips the file input loop and exits the program. Try For Each landingPage As String In landingPages pgbar.Timer1.Stop() If VisitedPages.Contains(landingPage) Then Continue For Else Dim thread = New Thread(AddressOf processQuery) count = count + 1 thread.Name = "Worm" & count thread.Start(landingPage) If numThread >= 10 Then For Each thread In ThreadList thread.Join() Next numThread = 0 Continue For Else numThread = numThread + 1 SyncLock ThreadList ThreadList.Add(thread) End SyncLock End If End If Next

  • UINavigationController Right button

    I am unable to set any property of parentController (which is always a UINavigationController in my case) from child views. e.g. I want to add a button on the navigation bar using following code: UINavigationController* parentController = (UINavigationController)self.parentViewController; UIBarButtonItem *addButton = [[[UIBarButtonItem alloc] initWithTitle:@"Something" style:UIBarButtonItemStyleBordered target:self action:@selector(doSomething)] autorelease]; [_parentController.navigationItem setRightBarButtonItem:addButton animated:YES]; This code runs perfectly without errors but I can't see any button added to the navigation bar. Thanks in advance.

  • Sqs vs SqsGen2 using RightScale right_aws GEM

    - by Fitter Man
    I'm trying to use the right_aws (1.10.0) GEM with Rails, and I've reduced my problem to a 3-line irb session. The following works require 'rubygems' require 'right_aws' sqs = RightAws::Sqs.new("xxxxxxxxxxxxxxx", "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx") while this fails require 'rubygems' require 'right_aws' sqs = RightAws::SqsGen2.new("xxxxxxxxxxxxxxx", "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx") with NameError: uninitialized constant RightAws::SqsGen2. I see the class definition in the GEM source, the documentation is old but seems accurate, but I can't figure out what I'm doing wrong. And while you're at it, is there any reason if I'm building something new, I'd want to use the older interface?

  • Tinyurl API Example - Am i doing it right :D

    - by Paul Weber
    Hi ... we use super-long Hashes for the Registration of new Users in our Application. The Problem is that these Hashes break in some Email Clients - making the Links unusable. I tried implementing the Tinyurl - API, with a simple Call, but i think it times out sometimes ... sometimes the mail does not reach the user. I updated the Code, but now the URL is never converted. Is Tinyurl really so slow or am i doing something wrong? (I mean hey, 5 Seconds is much in this Times) Can anybody recommend me a more reliable service? All my Fault, forgot a false in the fopen. But i will leave this sample of code here, because i often see this sample, wich i think does not work very reliable: return file_get_contents('http://tinyurl.com/api-create.php?url='.$u); This is the - i think fully working sample. I would like to hear about Improvements. static function gettinyurl( $url ) { $context = stream_context_create( array( 'http' => array( 'timeout' => 5 // 5 Seconds should be enough ) ) ); // get tiny url via api-create.php $fp = fopen( 'http://tinyurl.com/api-create.php?url='.$url, 'r', $context); // open (read) api-create.php with long url as get parameter if( $fp ) { // check if open was ok $tinyurl = fgets( $fp ); // read response if( $tinyurl && !empty($tinyurl) ) // check if response is ok $url = $tinyurl; // set response as url fclose( $fp ); // close connection } // return return $url; // return (tiny) url }

  • right usage of std::uncaught_exception in a destructor

    - by Vokuhila-Oliba
    There are some articles concluding "never throw an exception from a destructor", and "std::uncaught_exception() is not useful", for example: http://www.gotw.ca/gotw/047.htm (written by Herb Sutter) But it seems that I am not getting the point. So I wrote a small testing example (see below). Since everything is fine with the testing example I would very appreciate some comments regarding what might be wrong with it. testing results: ./main Foo::~Foo(): caught exception - but have pending exception - ignoring int main(int, char**): caught exception: from int Foo::bar(int) ./main 1 Foo::~Foo(): caught exception - but *no* exception is pending - rethrowing int main(int, char**): caught exception: from Foo::~Foo() // file main.cpp // build with e.g. "make main" // tested successfully on Ubuntu-Karmic with g++ v4.4.1 #include <iostream> class Foo { public: int bar(int i) { if (0 == i) throw(std::string("from ") + __PRETTY_FUNCTION__); else return i+1; } ~Foo() { bool exc_pending=std::uncaught_exception(); try { bar(0); } catch (const std::string &e) { // ensure that no new exception has been created in the meantime if (std::uncaught_exception()) exc_pending = true; if (exc_pending) { std::cerr << __PRETTY_FUNCTION__ << ": caught exception - but have pending exception - ignoring" << std::endl; } else { std::cerr << __PRETTY_FUNCTION__ << ": caught exception - but *no* exception is pending - rethrowing" << std::endl; throw(std::string("from ") + __PRETTY_FUNCTION__); } } } }; int main(int argc, char** argv) { try { Foo f; // will throw an exception in Foo::bar() if no arguments given. Otherwise // an exception from Foo::~Foo() is thrown. f.bar(argc-1); } catch (const std::string &e) { std::cerr << __PRETTY_FUNCTION__ << ": caught exception: " << e << std::endl; } return 0; }

  • What happens when you click a button using WebRat under cucumber

    - by Peter Tillemans
    I am trying to login to a Java web application.

I have no idea why the response.body is gone. I have no idea where I am. I speculated that I had to wait for the page request, but all documentation says that webrat nicely waits till all redirects, pageloads, etc are finished. (At least I think I read that). Besides I find no method to wait for the page in the webrat API. Can someone give some tips on how to proceed with debugging this?

  • Counting keystrokes and clicks in vb.net

    - by Cyclone
    I'm trying to create an application similar to the site WhatPulse, which will generate an image with my clicks and keystrokes. WhatPulse only updates the image once every 24 hours, so I am going to make an application to keep track of that for me, only with realtime stats. How can I count total keystrokes (outside of the application itself) as well as total clicks, in vb.net? This is for personal use. Thanks for your help!

  • Is Programming Right for me?

    - by L1th1um
    I'm interested in programming, but it seems to me that I can't get into it. Every time I've tried to learn a language and stuff by looking through tutorials or books I'd never get past the part where I use the syntax to make something. And by interest, I mean that I read stack overflow a lot, coding horror, and stuff but the actual coding part is hard for me to get into. Did anybody start this way? How did you get past this block?

  • help me pick the right iPhone audio class - MPMoviePlayer vs AVAudioPlayer vs MPMusicPlayer

    - by huevos de oro
    Does anyone know of a good tutorial on the distinction between the MPMoviePlayer vs AVAudioPlayer vs MPMusicPlayer? I want to play audio from an mp3 file available at an external URL. Ideally it is played in an iPod-like audio view. I toyed with MPMoviePlayer but it appears to be more suitable for video, as when audio starts a "movie playing" message displays, the controls disappear and a white quicktime splash page displays. I would like the standard ipod audio controls to display all the time, and to customize the image behind them.

  • Trigger jQueryUI datePicker on button click, send result to disabled input field

    - by Enrique
    Hi I've been searching for a way to do this, but could not find anything I want to have a: a disabled input text field, called #XX. This input will store the selected value from datepicker (as this input is disabled I won't be able to use this to trigger the datePicker) A button, besides #XX. When user clicks this button, datePicker will show. User will select the date, and this date will be assigned to disabled input #XX. I want this so user can't change manually -by typing crap- the selected date Also, should I validate if date was entered using #XX.val()? or is there a better way? Thanks

  • Right way to center a <div> in xhtml?

    - by Meredith
    Im working with a XHTML 1.0 Transitional doctype html file, and I want to have a main div with 800px width and make it appears centered (not the div content, but the div itself). I've used this on the past: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <style> <!-- html, body { margin:0; padding:0; } #main-container { background:black; width:800px; } --> </style> </head> <body> <center> <div id="main-container"> Content </div> </center> </body> </html> But I am not sure if this is cross-browser compatible, or if its valid xhtml.

  • Filter on button click D3.js?

    - by user1461701
    I'm working on a version of this bubble chart http://vallandingham.me/vis/gates/. As I'm using a different set of data - instead of the "All Grants" and "Grants by Year" buttons - I have one for 5 consecutive years - 2010, 2009 etc. My opening graph depicts the data for 2010 which is achieved by filtering the data from the .csv file , which contains the data for all 5 years. The problem I'm having is filtering and re-rendering the graph if another year is then chosen. I'd really appreciate it if anyone has any suggestions how I could simply achieve this? Thanks, Majella

    - by Mason Blier
    Hey all, I'm working on a project and I'm wondering how to get a type of window common in Windows's wireless controls, as shown in the screen shot below: http://cybernetnews.com/wp-content/uploads/2008/10/windows-7-wireless.jpg There's no close or maximize buttons, but the border is still present. My tools include Expression Blend 3 and Visual Studio 08. I was also wondering what the font used on these are, as it doesn't seem to be the normal Tahoma found in Office 7. Thanks, Mason

    - by Younes
    I have a class "Artikel" and there i write some Business Logic. I also have a class "tArtikel" which is a type. In my class "Artikel" I work with "tArtikel" and returns are of that type. Now when i instantiate an "Artikel" i want it to be of type "tArtikel", so what i tried in my code is: public tArtikel Artikel() { tArtikel artikel = new tArtikel(); } Which results in: "'Artikel' member names cannot be the same as their enclosing type". How would i set this up correctly?

  • Choosing the right template engine

    - by asrijaal
    Hi there, since today - I always used simple JSP Tags and JSTL which works but now I'm looking for a little bit more features and maybe more usability. With googling I've found Freemaker, Velocity and Tiles which seem to be very famous. Does someone of you has some further experiences with some of these and can give me a short brief about it. Or are there other frameworks which are worth to look into?

  • No middle-click scrolling in visual studio 2010?

    - by maxp
    Just as I started to assume this feature was ubiquitous(middle-clicking on a page, then scrolling speed/direction is relative to the distance of the pointer on the y-axis). I can't believe this hasn't been implemented into the text editor in vs2010, I used it all the time in 2005 and 2008. Has anyone managed to find a workaround or am I a minority user of this feature?

  • Choosing the right web service

    - by Ratan Sharma
    My website currently working in ASP.NET 1.1 Old Process In our database we have huge amount of data stored for a decoding purpose. We have to update this huge set of data table each week(Data is supplied from a vendor). In our website (in asp.net 1.1) we query our database to decode information. New process Now instead of storing data in our database and query them, we want to replace this through the web service, AS now the vendor is supplying us a DLL, which will give us the decoded information. Information on the DLL provided by the vendor The DLL provided, can only be added in 4.0 sites. SO that also impleies that i can not directly add the dll to my 1.1 site. This DLL is exposing certain methods, we simply have to add the DLL refernce in our web service and call the method and fetch the needed information. Thus we will not have to store those information in our database. So which type of web service I should go for (asmx OR WCF) that will use the DLLs provided by vendor to fetch the decoded information ?? Flexibility i am looking for in the web service are: It can be consumed from asp.net 1.1 site directly and also using jQuery ajax. It can be consumed from other web services running on the server. It can be consumed from some windows services running from the server. NOTE : Moreover we have a plan to migrate our website from asp.net 1.1 to 4.0 version in future.So it should be that much supportive for future upgrade.
