• PHP Prepared Statement Returns -1

  - by pws5068

  I've been using prepared statements for a little while now and I've never had any problems. Now I'm trying to: $sql="SELECT PhotoID,Caption FROM Photos WHERE EntityID=? AND TypeID=? LIMIT ?,?"; $iDB = new mysqliDB(); // Extends mysqli $stmt = $iDB->prepare($sql); $stmt->bind_param('iiii',$entityID,$typeID,$minRange,$maxRange); $stmt->execute(); $stmt->bind_result($photoID,$caption); echo("Affected={$stmt->affected_rows}"); This prints -1. I have triple tested that all 4 values in bindParam are set, and that the sql query works when pasted into myAdmin with the respective values. Any idea what may be causing this?

• VB.NET function that takes other functions as a parameter, and executes them

  - by rob

  Hello, Is there a way in vb.net to create a sub/function that will take as an argument some kind of pointer to another function, and allow this new sub/function to execute the passed function? What I have are 10-12 xml-rpc functions I am calling against a remote server. Each of these functions has different argument lists (one takes 1 string, another might take 3 strings and one int, etc). All of them return an object. As I am calling these, it seems like it should be able to be factored better. For instance, everytime I call any of these functions, I want to test the return value for a session drop, and do something to try and reconnect to the remote system, etc. Using .net 3.5 Thanks! -R

• SELinux, Fedora, and Trusted Applet crashing?

  - by Stefan Kendall

  For some reason, if I run Firefox 3.5.x under Fedora 11 with SELinux enabled, my browser crashes when I attempt to embed the applet dynamically. Under Windows, Ubuntu, and Mac, the user is prompted to trust the signer and then trust the executing java applet, but under Fedora, I never see this prompt. If I disable SELinux, I get NO prompting, and the applet embeds without any notice whatsoever! Remembering that trusted applets can execute user programs and manipulate user data, this becomes quite a nightmare. Has anyone else had to deal with SELinux and Fedora/SuSE/Linux and trusted applets before? If so, how did you overcome this broken behavior?

• How to make Spring accept non-void setters?

  - by Chris

  Hi, I have an API which I am turning into an internal DSL. As such, most methods in my PoJos return a reference to this so that I can chain methods together declaratively as such (syntactic sugar). myComponent .setID("MyId") .setProperty("One","1") .setProperty("Two","2") .setAssociation(anotherComponent) .execute(); My API does not depend on Spring but I wish to make it 'Spring-Friendly' by being PoJo friendly with zero argument constructors, getters and setters. The problem is that Spring seems to not detect my setter methods when I have a non-void return type. The return type of this is very convenient when chaining together my commands so I don't want to destroy my programmatic API just be to compatible with Spring injection. Is there a setting in Spring to allow me to use non-void setters? Chris

• Strange php behaviour on a gd function

  - by mck89

  Hi, i met a very strange PHP behaviour, i don't understand why it behaves like this. I'm using the imagesetbrush function in this way: class foo { function setbrush($image) { //$this->_resource contains the main image resource imagesetbrush($this->_resource, $image); } } ... $res=imagecreatefrompng("image.png"); $class->setbrush($res); in this way it works, but if i change the code like this: class foo { function setbrush($image) { $res=imagecreatefrompng($image); imagesetbrush($this->_resource, $res); } } ... $class->setbrush("image.png"); it doesn't work anymore. Do you see some error? It doesn't show me any message it simply doesn't execute the function.

• jQuery plugin, return value from function

  - by Marius

  Hello there, Markup: <input type="text" name="email" /> Code: $(':text').focusout(function(){ $(this).validate(function(){ $(this).attr('name'); }); }); Plugin: (function($){ $.fn.validate = function(type) { return this.each(function(type) { if (type == 'email') { matches = this.val().match('/.+@.+\..{2,7}/'); (matches != null) ? alert('valid') : alert('invalid'); } /*else if (type == 'name') { } else if (type == 'age') { } else if (type == 'text') { }*/ else { alert('total failure'); } }); }; })(jQuery); The problem is that when I execute the code above, it runs the plugin as if type was a string: "function(){ $(this).attr('name'); });" instead of executing it as a function. How do I solve this? Thank you for your time. Kind regards, Marius

• unit test service layer - NUnit, NHibernate

  - by csetzkorn

  Hi, I would like to unit test a DEPENDENT service layer which allows me to perform CRUD operation without mocking using NUnit. I know this is probably bad practice but I want to give it a try anyway - even if the tests have to run over night. My data is persisted using NHibernate and I have implemented a little library that 'bootstraps' the database which I could use in a [Setup] method. I am just wondering if someone has done something similar and what the fastest method for bootstrapping the database is. I am using something like this: var cfg = new Configuration(); cfg.Configure(); cfg.AddAssembly("Bla"); new SchemaExport(cfg).Execute(false, true, false); to establish the db schema. After that I populate some lookup tables from some Excel tables. Any feedback would be very much appreciated. Thanks. Christian

• How to call webservice using same credentials as Sharepoint?

  - by Saab

  Is it possible to do a webservice call from within an Excel sheet that has been downloaded from a sharepoint server, using the same credentials as the ones that are used for accessing the Sharepoint server? We're currently developing an Excel solution, which does webservice request from within the Excel sheet. This works fine, but the user has to log in at least twice : one for downloading/opening the Excel sheet from Sharepoint, and one to be able to execute the webservice using the right credentials. The Sharepoint server and the client machine are not in the same Active Directory domain. So "System.Security.Principal.WindowsIdentity.GetCurrent()" is not an option, since this will return a user that doesn't exist on the server.

• How to force oracle to use index range scan?

  - by wsb3383

  Hi, all. I have a series of extremely similar queries that I run against a table of 1.4 billion records (with indexes), the only problem is that at least 10% of those queries take 100x more time to execute than others. I ran an explain plan and noticed that the for the fast queries (roughly 90%) Oracle is using an index range scan (on my created), while on the slow one, it's using a full index scan. Is there a way to force Oracle to do a an index range scan? Thanks!

• Difference between piping a file to sh and calling a shell file

  - by Peter Coulton

  This is what was trying to do: $ wget -qO- www.example.com/script.sh | sh which quietly downloads the script and prints it to stdout which is then piped to sh. This unfortunately doesn't quite work, failing to wait for user input a various points, aswell as a few syntax errors. This is what actually works: $ wget -qOscript www.example.com/script.sh && chmod +x ./script && ./script But what's the difference? I'm thinking maybe piping the file doesn't execute the file, but rather executes each line individually, but I'm new to this kind of thing so I don't know.

• Completing install of ruby 1.9.3 with Ruby for for Mac OS X 10.7.5 Leopard, Xcode 4.5.2 -- problems with rvm pkg install openssl

  - by user1848361

  First, many thanks in advance for any help. I'm a complete novice with programming and I'm trying to get started with this Ruby on Rails tutorial (http://ruby.railstutorial.org/ruby-on-rails-tutorial-book?version=3.2) I have been trying figure this out for about 7 hours now and since I don't have any hair left to pull out I'm turning to these hallowed pages. I have searched for solutions here again and again. System: Mac OS X 10.7.5 Leopard, Xcode 4.5.2 I installed homebrew and have updated it multiple times I used homebrew to install rvm and have updated it multiple times I installed git The standard ruby on the system (checking with $ ruby -v) is 1.8.7 My problem is that every time I try to use rvm to install a new version of Ruby ($ rvm install 1.9.3) I get the following error: Ruby (and needed base gems) for your selection will be installed shortly. Before it happens, please read and execute the instructions below. Please use a separate terminal to execute any additional commands. Notes for Mac OS X 10.7.5, Xcode 4.5.2. For JRuby: Install the JDK. See http://developer.apple.com/java/download/ # Current Java version "1.6.0_26" For IronRuby: Install Mono >= 2.6 For Ruby 1.9.3: Install libksba # If using Homebrew, 'brew install libksba' For Opal: Install Nodejs with NPM. See http://nodejs.org/download/ To use an RVM installed Ruby as default, instead of the system ruby: rvm install 1.8.7 # installs patch 357: closest supported version rvm system ; rvm gemset export system.gems ; rvm 1.8.7 ; rvm gemset import system.gems # migrate your gems rvm alias create default 1.8.7 And reopen your terminal windows. Xcode and gcc: : I have performed $ brew install libksba and when I try to do it again it tells me that libksba is installed already. When I type "$ rvm requirements" I get: Notes for Mac OS X 10.7.5, Xcode 4.5.2. For JRuby: Install the JDK. See http://developer.apple.com/java/download/ # Current Java version "1.6.0_26" For IronRuby: Install Mono >= 2.6 For Ruby 1.9.3: Install libksba # If using Homebrew, 'brew install libksba' For Opal: Install Nodejs with NPM.

Xcode and gcc: Right now Ruby requires gcc to compile, but Xcode 4.2 and later no longer ship with gcc. Instead they ship with llvm-gcc (to which gcc is a symlink) and clang, neither of which are supported for building Ruby. Xcode 4.1 was the last version to ship gcc, which was /usr/bin/gcc-4.2. Xcode 4.1 and earlier: - Ruby will build fine. Xcode 4.2 and later (including Command Line Tools for Xcode): - If you have gcc-4.2 (and friends) from an earlier Xcode version, Ruby will build fine. - If you don't have gcc-4.2, you have two options to get it: * Install apple-gcc42 from Homebrew * Install osx-gcc-installer Homebrew: If you are using Homebrew, you can install the apple-gcc42 and required libraries from homebrew/dupes: brew update brew tap homebrew/dupes brew install autoconf automake apple-gcc42 rvm pkg install openssl Xcode 4.2+ install or/and Command Line Tools for Xcode is required to provide make and other tools. osx-gcc-installer: If you don't use Homebrew, you can download and install osx-gcc-installer: https://github.com/kennethreitz/osx-gcc-installer. Warning: Installing osx-gcc-installer on top of a recent Xcode is known to cause problems, so you must uninstall Xcode before installing osx-gcc-installer. Afterwards you may install Xcode 4.2+ or Command Line Tools for Xcode if you desire. ** NOTE: Currently, Node.js is having issues building with osx-gcc-installer. The only fix is to install Xcode over osx-gcc-installer. So I assume I have to do something with brew update brew tap homebrew/dupes brew install autoconf automake apple-gcc42 rvm pkg install openssl Everything seemed to work fine until "$ rvm pkg install openssl", which returns: Fetching openssl-1.0.1c.tar.gz to /Users/thierinvestmentservices/.rvm/archives Extracting openssl to /Users/thierinvestmentservices/.rvm/src/openssl-1.0.1c Configuring openssl in /Users/thierinvestmentservices/.rvm/src/openssl-1.0.1c.

• Zend Framework - applying order by on a nested query

  - by Gublooo

  Hey guys This might be a very simple thing. Check out the normal sql query below (select * from shopping order by shopping_id desc limit 5) order by RAND() This query runs successfully in mysql - not sure if this is the right way of doing it - but it works. It gets the last 5 ids from shopping table and randomly orders them everytime I want to achieve this in Zend. I'm not sure how to execute the first part and then apply the RAND clause to the results - what I have below does not do that. $select = $this-select() -from(array('sh'='shopping')) -order('shopping_id desc') -limit(5) -order('RAND()');

• Executing shell commands from Java

  - by Lauren?iu Dascalu

  Hello, I'm trying to execute a shell command from a java application, on the GNU/Linux platform. The problem is that the script, that calls another java application, never ends, although it runs successfully from bash. I tried to debug it: (gdb) bt #0 0xb773d422 in __kernel_vsyscall () #1 0xb7709b5d in pthread_join (threadid=3063909232, thread_return=0xbf9cb678) at pthread_join.c:89 #2 0x0804dd78 in ContinueInNewThread () #3 0x080497f6 in main () I tried with: ProcessBuilder(); and Runtime.getRuntime().exec(cmd); Looks like it waits for something to finish. Any ideas? Thanks, Lauren?iu

• java.lang.Void in C#?

  - by user313661

  Hi, I am currently working with .Net 2.0 and have an interface whose generic type is used to define a method's return type. Something like interface IExecutor<T> { T Execute() { ... } } My problem is that some classes that implement this interface do not really need to return anything. In Java you can use java.lang.Void for this purpose, but after quite a bit of searching I found no equivalent in C#. More generically, I also did not find a good way around this problem. I tried to find how people would do this with delegates, but found nothing either - which makes me believe that the problem is that I suck at searching :) So what's the best way to solve this? How would you do it? Thanks!

• What might cause SQL error Cannot find the object "dbo.InspectionEvents" because it does not exist o

  Hi My ASP.Net app is periodically getting the error 'Cannot find the object dbo."XXXX" because it does not exist or you do not have permissions' when it tries to execute a specific stored procedure that writes to the database. I have seen a few forum posts about this issue but the strange thing is that the method works fine almost all of the time, just every now and then I see it in my error logs. Can anyone tell me why this might works Ok most of the time but occassionally fire the error? Application is C# using Enterprise Library 4.1 Data Access. Database is SQL Server 2005 Cheers

• Browser for cross-site-script testing (for testing Mozilla Add-On)

  - by Anthony

  I am working on a Firefox extension that will involve ajax calls to domains that would normally fail due to the same-origin policy set by Firefox (and most modern browsers). I was wondering if there is a way to either turn off the same-origin restriction (in about:config, perhaps) or if there was a standard lite-browser that developers turn to for this. I really would like to avoid using any blackhat tools, if possible. Not because I'm against them, I just don't want to add another learning curve to the process. I can use curl in PHP to confirm that the requests work, but I want to get started on writing the js that the addon will actually use, so I need a client that will execute js. I also tried spidermonkey, but since I'm doing the ajax with jquery, it threw a fit at all of the browser-based default variables. So, short version: is there a reliable browser/client for cross site scripting that isn't primarily a hacker app? Or can I just turn off same-domain policy in Firefox?

• how to use a tree data structure in C#

  - by matti

  I found an implementation for a tree at this SO question. Unfortunately I don't know how to use it. Also I made a change to it since LinkedList does not have Add method: delegate void TreeVisitor<T>(T nodeData); class NTree<T> { T data; List<NTree<T>> children; public NTree(T data) { this.data = data; children = new List<NTree<T>>(); } public void AddChild(T data) { children.Add(new NTree<T>(data)); } public NTree<T> GetChild(int i) { return children[i]; } public void Traverse(NTree<T> node, TreeVisitor<T> visitor) { visitor(node.data); foreach (NTree<T> kid in node.children) Traverse(kid, visitor); } } I have class named tTable and I want to store it's children and their grandchildren (...) in this tree. My need is to find immediate children and not traverse entire tree. I also might need to find children with some criteria. Let's say tTable has only name and I want to find children with names matching some criteria. tTables constructor gives name a value according to int-value (somehow). How do I use Traverse (write delegate) if I have code like this; int i = 0; Dictionary<string, NTree<tTable>> tableTreeByRootTableName = new Dictionary<string, NTree<tTable>>(); tTable aTable = new tTable(i++); tableTreeByRootTableName[aTable.Name] = new NTree(aTable); tableTreeByRootTableName[aTable.Name].AddChild(new tTable(i++)); tableTreeByRootTableName[aTable.Name].AddChild(new tTable(i++)); tableTreeByRootTableName[aTable.Name].GetChild(1).AddChild(new tTable(i++));

• Unable to catch exception from Activator.CreateInstance.

  OK, I admit it this code will just look weird to you, and that's because it is weird. This is just code to reproduce the behavior, not code I want to use. class Program { static void Main(string[] args) { try { Activator.CreateInstance(typeof(Func<int>), new object[] { new object(), IntPtr.Zero }); } catch { Console.WriteLine("This won't print!"); } Console.Write("Actually this will not print either!"); Console.ReadLine(); } } No matter what exception type I try to catch (the actual exception thrown is an ArgumentException as far as I can tell) the code inside the catch block will not execute. Actually execution will just stop at the Activator.CreateInstance-line.

• Launching Vim via Lua

  - by Keith Pimmel

  I'm writing a simple little Lua commandline app that will build a static website. I'm storing my fragments in a sqlite database. Retrieving the data from the db is straightforward as is saving it; my question comes from editing the data. Is there an elegant way to pipe the data from Lua to vim? Can vim edit a memory buffer and return it? I was planning on launching the editor via os.execute('vim') but only after grabbing a temporary file handle and dumping the database output into that. I would like to have to avoid touching the filesystem that way but that is my contingency plan.
