• CSV parser in C++

  - by User1

  All I need is a good CSV file parser for C++. At this point it can really just be a comma-delimited parser (ie don't worry about escaping new lines and commas). The main need is a line-by-line parser that will return a vector for the next line each time the method is called. I found this article which looks quite promising: http://www.boost.org/doc/libs/1_35_0/libs/spirit/example/fundamental/list_parser.cpp I've never used Boost's Spirit, but am willing to try it. Is it overkill/bloated or is it fast and efficient? Does anyone have faster algorithms using STL or anything else? Thanks!

• How can I use Perl to scrape a website that reveals its content with JavaScript?

  - by AmbroseChapel

  I need to write a Perl script to scrape a website. The website can only be scraped with JavaScript, and the user is on Windows. I got some way with Win32::IE::Mechanize on my work machine, which has IE6, but then I moved to my netbook which has IE8, and can't even get as far as fetching a simple page. Is Win32::IE::Mechanize up to date with the latest versions of IE? But, more to the point, given a recent WinXP machine, what's the quickest, easiest way to scrape a site which only reveals its content via JavaScript?

• C++/g++: Concurrent programm

  - by phimuemue

  Hi, I got a C++ program (source) that is said to work in parallel. However, if I compile it (I am using Ubuntu 10.04 and g++ 4.4.3) with g++ and run it, one of my two CPU cores gets full load while the other is doing "nothing". So I spoke to the one who gave me the program. I was told that I had to set specific flags for g++ in order to get the program compiled for 2 CPU cores. However, if I look at the code I'm not able to find any lines that point to parallelism. So I have two questions: Are there any C++-intrinsics for multithreaded applications, i.e. is it possible to write parallel code without any extra libraries (because I did not find any non-standard libraries included)? Is it true that there are indeed flags for g++ that tell the compiler to compile the program for 2 CPU cores and to compile it so it runs in parallel (and if: what are they)?

• How can I use cURL to open multiple URLs simultaneously with PHP?

  - by Rob

  Here is my current code: $SQL = mysql_query("SELECT url FROM urls") or die(mysql_error()); //Query the urls table while($resultSet = mysql_fetch_array($SQL)){ //Put all the urls into one variable // Now for some cURL to run it. $ch = curl_init($resultSet['url']); //load the urls curl_setopt($ch, CURLOPT_TIMEOUT, 2); //No need to wait for it to load. Execute it and go. curl_exec($ch); //Execute curl_close($ch); //Close it off } //While loop I'm relatively new to cURL. By relatively new, I mean this is my first time using cURL. Currently it loads one for two seconds, then loads the next one for 2 seconds, then the next. however, I want to make it load ALL of them at the same time. I'm sure its possible, I'm just unsure as to how. If someone could point me in the right direction, I'd appreciate it.

• Grails Services / Transactions / RuntimeException / Testing

  - by Rob

  I'm testing come code in a service with transactional set to true , which talks to a customer supplied web service the main part of which looks like class BarcodeService { .. /// some stuff ... try{ cancelBarCodeResponse = cancelBarCode(cancelBarcodeRequest) } catch(myCommsException e) { throw new RuntimeException(e) } ... where myCommsException extends Exception .. I have a test which looks like // As no connection from my machine, it should fail .. shouldFailWithCause(RuntimeException){ barcodeServices.cancelBarcodeDetails() } The test fails cause it's catching a myCommsException rather than the RuntimeException i thought i'd converted it to .. Anyone care to point out what i'm doing wrong ? Also will the fact that it's not a RuntimeException mean any transaction related info done before my try/catch actually be written out rather than thrown away ?? Thanks

• Interview Programming Questions - In house Exam

  - by David McGraw

  I have a company that would like to bring me in to serve me an hour long exam. No resources other than a pencil and paper. I really couldn't get any sort of feedback on the type of exam (implementation or generic) beside that it would test a few specific areas. Have you done anything like this? What sort of questions did they ask? What's a good way to prepare? I'll probably go in a couple weeks before school starts back up. A time sensitive exam structure is a weak point for me, so what should I absolutely focus down on? If they like the exam, that's when I'll get a face-to-face meeting. An advance thanks goes to everybody who provide their time.

• WCF host address question

  - by Estelle

  when I setup the wcf service on a web server, I set the end point address as <endpoint address="http://www.mydomin.com/clientname/happy.svc" binding="basicHttpBinding" name="happysvcbasic" contract="happysvc.Ihappysvc"> </endpoint> but when type in above address on a browser, I get a different host name, which is the internal server name, such as, To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax: svcutil.exe http://internalservername.domain/clientname/happy.svc?wsdl I tried to add the host/baseaddress tag, but make no difference, what I missed? thanks for help.

• Inheritance: possible to change base reference to something else?

  - by fred

  For example I have two classes, Base and Derived as shown below: class Base { public string Name { get; set; } public Base() { } } class Derived : Base { public Derived(Base b) { base = b; // doesn't compile, but is there any way to do something similar? } } So that they behave like this: Base b = new Base(); b.Name = "Bob"; Derived d = new Derived(b); d.Name = "John"; // b.Name is now "John" also Is this possible? I guess one way would be to keep the Base b reference in Derived and override Derived.Name to point to b.Name? Is there an easier way though, for example if I have like 50 properties to override? class Derived : Base { Base b; public override string Name { get { return b.Name; } set { b.Name = value; } } public Derived(Base b) { this.b = b; } }

• PHP: find 2 or more numbers from a list of N numbers that can add up towards a given ammount

  - by Splash

  Hi Guys, I am trying to create a little php script that can make my life a bit easier. Basically, I am going to have 21 text fields on a page where I am going to input 20 different numbers. In the last field I will enter a number let's call it the TOTAL AMMOUNT. All I want the script to do is to point out which numbers from the 20 fields added up will come up to TOTAL AMMOUNT. Example: field1= 25.23 field2= 34.45 field3= 56.67 field4= 63.54 field5= 87.54 .... field20= 4.2 Total Ammount= 81.90 Output: field1+fields3=81.90 Some of the fields might have 0 as value because sometimes I only need to enter 5-15 fields and the maximum will be 20. If someone can help me out with the php code for this, will be greatly appreciated.

• How can I check with a regex that a string contains only certain allowed characters?

  - by Camran

  I need a special regular expression, have no experience in them whatsoever so I am turning to you guys on this one: I need to validate a classifieds title field so it doesn't have any special characters in it, almost. Only letters and numbers should be allowed, and also the swedish three letters å, ä, ö, and also not case sensitive. Besides the above, these should also be allowed: The "&" sign. Parenthesis sign "()" Mathematical signs "-", "+", "%", "/", "*" Dollar and Euro signs One accent signed letter: "é". //Only this one is required Double quote and singel quote signs. The comma "," and point "." signs Thanks

• Hudson + gitolite + virtual host on staging server

  - by takeshin

  I have a Ubuntu server which I want to be my continous integration server (for the Zend Application based projects) and the staging server as well. The team is pushing source files to the repository: /home/git/repositories/testing.git Then Hudson does the build, and the master branch is exported (maybe cloned is a better word) by git hudson plugin to: /var/lib/hudson/jobs/test/workspace/ The workspace contains .git folder as well, which is not necessary on my staging website. How do you set up virtual host to see the staging version of the content of the repository? Does the virtual host point to the workspace, or shall I export the files to another directory? What about the permissions and security? Hudson is the owner of all the workspace files. Do I have to do some post-build actions to set up access? P.S. If this question is more apropriate to serverfault, please migrate.

• Assorted list of what's new in Delphi [Language, RTL, VCL]?

  - by utku_karatas

  Hi gents, As someone who's been stuck at the older versions of Delphi and upgraded to D2010 lately, I figure I still use the language, RTL and VCL features from the D5 era and refrain from using these new features as the documents on those are somewhat decentralized around the blogosphere. So I'd like to ask if there was an assorted list like what's new docs of Python's - clear and concise to the point. Btw, please no screencasts. They seem to be quite abundant lately (probably because of CodeRages) but I find them very unintuitive to learn from. Let's leave that docs in video format thing to RoR community, shall we :).

• Oracle function always returning null

  - by JavaRocky

  I can't get this function to behave as i desire. Can anyone point out why it always returns null instead of CURRENT_TIMESTAMP? CREATE OR REPLACE FUNCTION nowts RETURN TIMESTAMP IS vTimestamp TIMESTAMP; BEGIN SELECT type_date INTO vTimestamp FROM param_table WHERE param_table = 3 AND exists ( SELECT * FROM param_table WHERE param_table = 2 ); IF vTimestamp IS NULL THEN vTimestamp := CURRENT_TIMESTAMP; END IF; return vTimestamp; END nowts; Right now there is nothing in the table named param_table.

• using APIs with oauth for single user

  - by Josh

  I'm trying to make use of various APIs including twitter, youtube, etc because we want to embed recent entries (tweets, videos) on our website. However, since I'm just retrieving my own data, I'm wondering how I can do this simpler than the multi-step process required by OAuth. Twitter provides me with my own access token I can use directly, so that kinda works, but I can't find any such token in the YouTube documentation. So how am I supposed to make use of the api if I just want to get a simple list of stuff? how exaclty am I supposed to authenticate my own website to use my own account? I think i might have things all wrong and if so please point me in the right direction. I tried using rss feeds but they don't give me as much control over what I retrieve as using the API directly... any insight or suggestions are appreciated!

• Why does the infobox in my MSN Map not close?

  - by meder

  I'm having a bit of trouble with this map, invoked by the "View our interactive map" button in the middle of the content area. If you double click a point such as 8 which causes a zoom and then afterwards it causes the info box to appear, the hide logic is wrong. If you try to close the x, it will fail. This is probably because the user clicked too fast and the map thinks its in zoom mode when infact it should be in info box mode. Has anyone ran into this issue before? Looks like I have to mess around with window.ero.hide and some other functions.. because map.HideInfoBox doesn't hide the map. EDIT: The script used is here. I did not code it, but the relevant bit has: onclick="EnableEroHide();map.HideInfoBox();changePin();return false;" The map.HideInfoBox() should hide the info box.

• Automatic people counting + twittering.

  - by c2h2

  Want to develop a system accurately counting people that go through a normal 1-2m wide door. and twitter whenever people goes in or out and tells how many people remain inside. Now, Twitter part is easy, but people counting is difficult. There is some semi existing counting solution, but they do not quite fit my needs. My idea/algorithm: Should I get some infra-red camera mounting on top of my door and constantly monitoring, and divide the camera image into several grid and calculating they entering and gone? can you give me some suggestion and starting point?

• IE sending through multiple unrequested requests for parent URL

  - by andyjeffries

  We have a rather large/complex web site (so it's not easy to extract portions of it). The problem we're having is that IE6/7/8 (but 6 is the worst) are sending through multiple requests for the parent of a URL (which fails, a different point). As an example, if you visited (dummy domain name obviously): http://www.example.com/view/event/123/456/78 We'd get 8-20 requests for: http://www.example.com/view/event/123/456/ appear in the Apache log. We've tried: Disabling all plugins (including toolbars, Flash, etc) Disabling scripting (e.g. Javascript) And it still sends through at least one erroneous request. We've viewed the requests through ieHttpHeaders so the browser is aware of them (i.e. it's not prefetching by the network's proxy). Any ideas? What can else could cause this?

• How to access the backing field of a base class using fluent nhibernate?

  - by Akk

  How do i set the Access Strategy in the mapping class to point to the base _photos field? public class Content { private IList<Photo> _photos; public Content() { _photos = new List<Photo>(); } public virtual IEnumerable<Photo> Photos { get { return _photos; } } public virtual void AddPhoto() {...} } public class Article : Content { public string Body {get; set;} } I am currently using the following to try and locate the backing field but an exception is thrown as it cannot be found. public class ArticleMap : ClassMap<Article> { HasManyToMany(x => x.Photos) .Access.CamelCaseField(Prefix.Underscore) //_photos //... } i tried moving the backing field _photos directly into the class and the access works. So how can i access the backing field of the base class?

• VB6 debugging- doesn't go to error handling code.

  - by Can Ho

  Hi, I'm maintaining a vb6 project(ActiveX DLL). When debugging, the app run into the following function: Public Function HasValue(ByVal vValue) As Boolean On Error GoTo Err If IsMissing(vValue) Then HasValue = False ElseIf IsNull(vValue) Or Len(vValue) = 0 Then HasValue = False ElseIf isEmpty(vValue) Then HasValue = False Else HasValue = True End If Exit Function Err: If IsArray(vValue) Or IsObject(vValue) Then HasValue = True Else HasValue = False End If End Function and it stops at the line ElseIf IsNull(vValue) Or Len(vValue) = 0 Then vValue is a custom object, contains some properties(obviously, not null). Although I didn't put any break point there, the app stopped there and alerted error dialog saying that "Run-time error '438': Object doesn't support this property or method". We had error handling code but the app didn't run to error handling code. It just stopped at the line causing the error and I had to stop the application. Do you have any idea about that? Thank you very much.

• Workaround for UnsupportedAudioFileException ?

  - by tschan

  I'm in a very early stage of writing a small music/rhythm game in Java (via Slick framework, which in turns uses OpenAL, but that's probably irrelevant here). The game needs to read (and playback) several sound files in WAV format, but some of the files are throwing [javax.sound.sampled.UnsupportedAudioFileException] exceptions. at javax.sound.sampled.AudioSystem.getAudioInputStream(AudioSystem.java:1102) at org.newdawn.slick.openal.WaveData.create(WaveData.java:123) at org.newdawn.slick.openal.SoundStore.getWAV(SoundStore.java:713) at org.newdawn.slick.openal.SoundStore.getWAV(SoundStore.java:683) at org.newdawn.slick.Sound.<init>(Sound.java:33) The files can be played back just fine in Winamp or Foobar2000, so this means Java just don't recognize some variants of the file format. What are my options at this point? Note: The files in question are user-supplied, so i cannot just convert them beforehand (using something like audacity). Any conversion steps must be done at runtime.

• How to "flick" a UIImageView?

  - by Meltemi

  I've got some UIViews that I'd like the user to be able to "flick" across the screen. They're not scroll views. They simply contain a raster image (png). Can anyone point me to some sample code, etc to help get me started? Something a little more heavyweight than "MoveMe" out there that helps detect a "flick" (vs a "nudge" or a drag and drop) and then carries the view off in the direction of the "flick"? OpenGL probably overkill. If possible I'd like to stay w/in the realm of Core Graphics/Animation.

• how to use a non standard tld with android

  - by CommentLuv

  I have rooted my android and am able to edit the hosts file to redirect .com and other standard tld's to my local server with no problems. non standard tld's do not work though. eg. my shop orders system is at http://fired.wok which works find on local machines when added to my windows and linux hosts files but is not resolvable from within my android device. I can use firedwok.co.uk) in the hosts file to point to my local machine but I'd much rather have fired.wok to work so I can use an android tablet to enter orders and deliveries. so, how to make android work with a tld like .wok ?

• database row/ record pointers

  - by David

  Hi I don't know the correct words for what I'm trying to find out about and as such having a hard time googling. I want to know whether its possible with databases (technology independent but would be interested to hear whether its possible with Oracle, MySQL and Postgres) to point to specific rows instead of executing my query again. So I might initially execute a query find some rows of interest and then wish to avoid searching for them again by having a list of pointers or some other metadata which indicates the location on a database which I can go to straight away the next time I want those results. I realise there is caching on databases, but I want to keep these "pointers" else where and as such caching doesn't ultimately solve this problem. Is this just an index and I store the index and look up by this? most of my current tables don't have indexes and I don't want the speed decrease that sometimes comes with indexes. So whats the magic term I've been trying to put into google? Cheers

• How to analyse Wikipedia article's data base with R?

  - by Tal Galili

  Hi all, This is a "big" question, that I don't know how to start, so I hope some of you can give me a direction. And if this is not a "good" question, I will close the thread with an apology. I wish to go through the database of Wikipedia (let's say the English one), and do statistics. For example, I am interested in how many active editors (which should be defined) Wikipedia had at each point of time (let's say in the last 2 years). I don't know how to build such a database, how to access it, how to know which types of data it has and so on. So my questions are: What tools do I need for this (besides basic R) ? MySQL on my computer? RODBC database connection? How do you start planning for such a project?

• Clicking Elements in Android Doesn't Display the Correct Values

  - by Devin

  I apologize if this code looks a bit like a mess (considering the length); I figured I'd just include everything that goes on in my program at the moment. I'm attempting to create a fairly simple Tic Tac Toe app for Android. I've set up my UI nicely so far so that there are a "grid" of TextViews. As a sort of "debug" right now, I have it so that when one clicks on a TextView, it should display the value of buttonId in a message box. Right now, it displays the correct assigned value for the first element I click, but no matter what I click afterwards, it always just displays the first value buttonID had. I attempted to debug it but couldn't exactly find a point where it would pull the old value (to the best of my knowledge, it reassigned the value). There's a good possibility I'm missing something small, because this is my first Android project (of any note). Can someone help get different values of buttonId to appear or point out the error in my logic? The code: package com.TicTacToe.app; import com.TicTacToe.app.R; //Other import statements public class TicTacToe extends Activity { public String player = "X"; public int ALERT_ID; public int buttonId; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //Sets up instances of UI elements final TextView playerText = (TextView)findViewById(R.id.CurrentPlayerDisp); final Button button = (Button) findViewById(R.id.SetPlayer); final TextView location1 = (TextView)findViewById(R.id.location1); final TextView location2 = (TextView)findViewById(R.id.location2); final TextView location3 = (TextView)findViewById(R.id.location3); final TextView location4 = (TextView)findViewById(R.id.location4); final TextView location5 = (TextView)findViewById(R.id.location5); final TextView location6 = (TextView)findViewById(R.id.location6); final TextView location7 = (TextView)findViewById(R.id.location7); final TextView location8 = (TextView)findViewById(R.id.location8); final TextView location9 = (TextView)findViewById(R.id.location9); playerText.setText(player); //Handlers for events button.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { // Perform action on click if (player.equals("X")){ player = "O"; playerText.setText(player); } else if(player.equals("O")){ player = "X"; playerText.setText(player); } //Sets up the dialog buttonId = 0; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 1; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 2; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location3.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 3; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location4.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 4; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location5.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 5; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location6.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 6; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location7.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 7; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location8.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 8; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); location9.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Sets up the dialog buttonId = 9; ALERT_ID = 0; onCreateDialog(ALERT_ID); showDialog(ALERT_ID); } }); } protected Dialog onCreateDialog(int id){ String msgString = "You are on spot " + buttonId; AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setMessage(msgString) .setCancelable(false) .setNeutralButton("Ok", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { dialog.cancel(); } }); AlertDialog alert = builder.create(); return alert; } }
