• C++/CLI .ToString() returning error

  - by George Johnston

  I am a beginner to C++/CLI as I come from a C# background. I am currently writing a wrapper for some native C++ code. I have the following methods: void AddToBlockList(System::String^ address) { char* cAddress = (char*)(void*)Marshal::StringToHGlobalAnsi(address); _packetFilter->AddToBlockList(cAddress); } void AddToBlockList(IPAddress^ address) { char* cAddress = (char*)(void*)Marshal::StringToHGlobalAnsi(address.ToString()); _packetFilter->AddToBlockList(cAddress); } ...The first method works fine and converts my string into the character array. However, the second function with the IPAddress object as the signiture gives me the following error: error C2228: left of '.ToString' must have class/struct/union ...When I type ? address.ToString() ...in the command window, the IP Address prints. Not sure where I'm going wrong. Any ideas?

• Java or php tree structure problem

  - by agazerboy

  Hi All, I have all my data in my database. It has following 4 columns id source_clust target_clust result_clust 1 7 72 649 2 9 572 650 3 649 454 651 4 32 650 435 This data is like tree structure. source_clust and target_clust generate target_clust. target_clust can be source_clust or target_clust to make a new target_clust. Is there any php function or class that I can use to generate tree structure for my data???? I see this MySql site they are doing exactly what I need but I couldn't find how to implement that query in my data. Thanks ! Edited Is there any way in java to do it? if we have same data in array ??

• Stuck at "Hello World" with IntelliJ IDEA 9.0.1 for Scala

  - by Alex R

  I've been using Eclipse since 2.x and and IDEs in general for over 20 years (since Turbo Pascal and Turbo C in the late '80s!). (that preamble is supposed to imply, "I'm not an idiot" ... LOL :-] ) I'm trying to use the debugger in IntelliJ 9.0.1. I've resigned myself to an old standby: class hello { def main(a: Array[String]) = println("got args: " + a) } Alas, I'm unable to get even this simple Scala example to run. I'd like to eventually put a breakpoint in it, but for now just running it would be great. I have Java 1.6u20 and the Scala plug-in 0.3.473 (January 2010). The error below summarizes my experience: What possibly could I be doing wrong? Thanks

Here's my test.sh: #!/bin/bash LIB=${0/%cli/} exec php -q ${LIB}test.php one two three exit; When I doubleclick on the test.sh file then it returns the argv array like it suppost to. But why can't I run it from terminal?

• Looping through JSON arrays

  - by George

  I'm trying to pull the field names in the header of some JSON output. The following is a sample of the JSON header info: {"HEADER":{"company":{"label":"Company Name"},"streetaddress":{"label":"Street Address"},"ceo":{"label":"CEO Name","fields":{"firstname":{"label":"First Name"},"lastname":{"label":"Last Name"}}} I'm able to loop through the header and output the field and label (i.e. company and Company Name) using the following code: obj = JSON.parse(jsonResponse); for (var key in obj.HEADER) { response.write ( obj.HEADER[key].label ); response.write ( key ); } but can't figure out how to loop through and output the sub array of fields (i.e. firstname and First Name). Any ideas?

• Suggestion for chkstk.asm stackoverflow exception in C++ with Visual Studio 2010

  - by Gulshan

  I am working with an implementation of merge sort. I am doing C++ Visual Studio 2010. But when I took a array of 300000 integers for timing, it is showing an unhandled stackoverflow exception and taking me to a readonly file named "chkstk.asm". I reduced the size to 200000 and it worked. Again the same code worked with C-free 4 editor (mingw 2.95) without any problem while the size was 400000. Do you have any suggestion to get the code working in Visual Studio? May be the recursion in the mergesort is causing the problem.

• InnoDB "Column count doesn't match value count at row 1"

  - by Webnet

  I'm having issues with a table. I'm using the following to create my insert query... $validatedData = array(); foreach ($post as $key => $value) { if ($key != 'submit' && $key != 'dz_tos' && $key != 'dz_billShip') { $validatedData[$key] = filter_var($value, FILTER_SANITIZE_STRING); } } mysql_query("INSERT INTO dz_users(".implode(array_keys($validatedData), ',').", dz_access_level) VALUES(\"".implode($validatedData, '\",\"')."\", 1)"); So every column has a value to match it. The problem is that I'm getting the SQL error: Column count doesn’t match value count at row 1 The database is an innoDB and all columns are varChar/Char except for the ID field which is an auto increment primary key.

• Computing unique index for every poker starting hand

  - by Aly

  As there are 52 cards in a deck we know there are 52 choose 2 = 1326 distinct matchups, however in preflop poker this can be bucketed into 169 different hands such as AK offsuit and AK suited as whether it is A hearts K hearts or A spade K spades it makes no difference preflop. My question is, is there a nice mathematical property in which I can uniquely index each of these 169 hands (from 0 to 168 preferably). I am trying to create a look up table as a double[][] = new double [169][169] but have no way of changing a hand representation such as AKs (an Ace and a King of the same suit) to a unique index in this array.

• NSDictionary with specific property of plist

  - by Leonardo

  Hi, I have a plist with key values. Each key represent a language, let's say 'it' 'en' ....ecc The value of each key is another key/value(=array) set. At startup I would like to create a dictionary by reading only a specific key. Let's say the locale of my iphone is 'it', then the init method would only parse it key, because the only way I found by now is to make a dictionary from the whole plist file and then another dictionary. But I can imagine this can become quite cpu consuming if I add more language in the future. thanks Leonardo

  Hello everyone, I have defined the following rule in the router.php file of my cakephp 1.3 based application Router::connect('/tags/*',array('plugin' => 'tags', 'controller' => 'Tags', 'action' => 'index', 'admin' => false)); I have used the tags plugin.

• Why does this code fail in D2010, but not D7?

  - by Tom1952

  Why does this code get an access error on the Result := Buffer line in D2010, but not D7? Something, I'd guess, involving UniCode, but the compiler doesn't generate any warnings. Any suggestions on an elegant workaround? function GetTempPathAndFileName( const aExtension: string): string; var Buffer: array[0..MAX_PATH] of Char; begin repeat GetTempPath(SizeOf(Buffer) - 1, Buffer); GetTempFileName(Buffer, '~', 0, Buffer); Result := Buffer; // <--- crashes on this line, Result := ChangeFileExt(Result, aExtension); until not FileExists(Result); end; { GetTempPathAndFileName }

• Cakephp: Correct way to resolve hasMany - hasMany relation

  - by Chris

  I have three models: Company, Car, Passenger Company hasMany Cars Car hasMany Passenger These relations seem to work independetly: Car shows all Passengers and Company shows all Cars. But I cannot resolve the Company - Passenger (Show all Passengers of a Company). My controller for Company: function index(){ //grab all companies and pass it to the view: $companies = $this->Company->find('all'); $this->set('companies', $companies); } This displays all companies with all their respective cars. However the array does not contain an entry for passenger. What do I have to do to completely resovle the Company - Car - Passenger relation?

• Can't get my head arround background workers in c#

  - by Connel

  I have wrote an application that syncs two folders together. The problem with the program is that it stops responding whilst copying files. A quick search of stack-overflow told me I need to use something called a background worker. I have read a few pages on the net about this but find it really hard to understand as I'm pretty new to programming. Below is the code for my application - how can I simply put all of the File.Copy(....) commands into their own background worker (if that's even how it works)? Below is the code for the button click event that runs the sub procedure and the sub procedure I wish to use a background worker on all the File.Copy lines. Button event: protected virtual void OnBtnSyncClicked (object sender, System.EventArgs e) { //sets running boolean to true booRunning=true; //sets progress bar to 0 prgProgressBar.Fraction = 0; //resets values used by progressbar dblCurrentStatus = 0; dblFolderSize = 0; //tests if user has entered the same folder for both target and destination if (fchDestination.CurrentFolder == fchTarget.CurrentFolder) { //creates message box MessageDialog msdSame = new MessageDialog(this, DialogFlags.Modal, MessageType.Error, ButtonsType.Close, "You cannot sync two folders that are the same"); //sets message box title msdSame.Title="Error"; //sets respone type ResponseType response = (ResponseType) msdSame.Run(); //if user clicks on close button or closes window then close message box if (response == ResponseType.Close || response == ResponseType.DeleteEvent) { msdSame.Destroy(); } return; } //tests if user has entered a target folder that is an extension of the destination folder // or if user has entered a desatination folder that is an extension of the target folder if (fchTarget.CurrentFolder.StartsWith(fchDestination.CurrentFolder) || fchDestination.CurrentFolder.StartsWith(fchTarget.CurrentFolder)) { //creates message box MessageDialog msdContains = new MessageDialog(this, DialogFlags.Modal, MessageType.Error, ButtonsType.Close, "You cannot sync a folder with one of its parent folders"); //sets message box title msdContains.Title="Error"; //sets respone type and runs message box ResponseType response = (ResponseType) msdContains.Run(); //if user clicks on close button or closes window then close message box if (response == ResponseType.Close || response == ResponseType.DeleteEvent) { msdContains.Destroy();

• Uncompressing zlib data using boost::iostreams::filtering_streambuf trouble

  - by GuitaringEgg

  I'm trying to write a small class that will load the chunk data from part of a minecraft world file. I'm to the point where I have stored some data in a char array which was compressed with zlib and need to decompress it. I'm trying to use the boost filtering_streambuf to do this. char * rawChunk = new char[length - 1]; // Load chunk data stringstream ssRawChunk(rawChunk); boost::iostreams::filtering_istream in; in.push(boost::iostreams::zlib_decompressor()); in.push(ssRawChunk); stringstream ssOut; boost::iostreams::copy(in, ssOut); My problem is that rawChunk contains null data, so when coping data from (char*) rawChunk to (stringstream) ssRawChunk, it terminates at ~257 instead of the expected length 2154. Is there any way to use filtering_streambuf without stringstream to allow for null data or is there a way to stop stringstream to not terminate on null data?

• Zend Framework REST service HTTP status code problem

The only way I can think of to remove the appended error document is to add the following in my httpd.conf file: ErrorDocument 201 " " But what's the "corrent" way of doing this?

• Zend Framework - POP3 - retrieving message source

  - by pako

  Is it possible to retrieve the complete message source (similar tu Unix Mbox format) using Zend_Mail_Storage_Pop3 from the Zend Framework? I'm using the following code to retrieve messages: $mail = new Zend_Mail_Storage_Pop3(array('host' => 'localhost', 'user' => 'test', 'password' => 'test')); echo $mail->countMessages() . " messages found\n"; foreach ($mail as $message) { echo "Mail from '{$message->from}': {$message->subject}\n"; } It looks like the $mail object contains the message already split up into fields (ie. headers, contents, etc.). Is there any way to retrieve the original message source? I would like to be able to store it so if I need to parse the message again using a different tool, I will have the necessary information.

• VC7.1 C1204 internal compiler error

  - by Nathan Ernst

  I'm working on modifying Firaxis' Civilization 4 core game DLL. The host application is built using VC7, hence the constraint (source not provided for the host EXE). I've been working on rewriting a large chunk of the code (focusing on low-hanging performance issues & memory leaks). I recently ran into an internal compiler error when trying to mod the code to use an array class instead of dynamically allocated 2-d arrays, I was going to use matrices from the boost lib (Civ4 is already using boost, so why not?). Basically, the issue comes down to: if I include "boost/numeric/ublas/matrix.hpp", I run into an internal compiler error C1204. MSDN has this to say: MSDN C1204 KB has this to say: KB 883655 So, I'm curious, is it possible to solve this error without a KB/SP being applied and dramatically reducing the complexity of the code? Additionally, as VC7 is no longer "supported", does anyone have a valid (supported) link for a VC7 service pack?

• Automatic counter in Ruby for each?

  - by yar

  I know you Ruby people will laugh at my bad Ruby code: i=0 for blah in blahs puts i.to_s + " " + blah i+=1 end I want to use a for-each and a counter... is there a better way to do it? Note: I don't know if blahs is an array or a hash, but having to do blahs[i] wouldn't make it much sexier. Also I'd like to know how to write i++ in Ruby. Edit: Technically, Matt's and Squeegy's answer came in first, but I'm giving best answer to paradoja so spread around the points a bit on SO. Also his answer had the note about versions, which is still relevant (as long as my Ubuntu 8.04 is using Ruby 1.8.6). Edit: Should've used puts "#{i} #{blah}" which is a lot more succinct.

• php question regarding arrays

  - by Martin

  Hi there, I'm a (complete) php noob and need a little help with something. I'm working on a project whereby a user can select up to 6 categories via a form (I'm using ExpressionEngine). The output is like this: "Cat1","Cat2","Cat3" ...and so on. The user can select up to 6 categories on that form. What I need: even if my result is 3 categories I need to have 6 'cells' - for want of a better word - even if they're empty: "Cat1","Cat2","Cat3","","","" I've tried this: <?php $str = '(output goes here)'; print_r(explode(',', $str, 6)); ?> ...but the output give me: Array ( [0] => Cat1 [1] => Cat2 [2] => Cat3 [3] => [4] => [5] => ) How do I get from that to this: "Cat1","Cat2","Cat3","","","" Does this make sense? Thanks Martin

• Regular Expressions: RegEx for determining valid PHP class property names?

  - by Brian Lacy

  I am using PHP's magic __set and __get methods to access a private array in a class. I want to make sure the property names requested (i.e. $myObj->FakeProperty) are valid according to PHP property name rules before accessing them. My current RegEx isn't doing the trick; with my test values, _12 always falls through the cracks. I'm not actually sure that my test values even represent a realistic representation of what is and isn't allowed for PHP class property names, but I'm not really too concerned about it, just that I have some sort of rudimentary check in place. Test Fields: albert12 12Albert _12 _Albert12 _12Albert _____a_1 RegEx: ^(?=_*[A-z]+)[A-z0-9_]+$
