• How to call Cocoa Methods from Applescript under Mac OS X 10.6

  - by Nico

  In former Mac OS x versions it was possible to call Cocoa methods via the "call method" command in applescript ("Applescript Studio"). E.g. this way: set theURL to "http://www.apple.com" set URLWithString to (call method "stringByAddingPercentEscapesUsingEncoding:" of theURL with parameter 30) The script interpreter in the "Applescript Editor" (10.6) does not understand the command "call method". - Is there an equivalent for "Applescript Editor" (10.6)?

• Adding nodes to drupal from remote site using ajax and post

  - by andersandersson666

  I'm trying to add nodes to my drupal site, from a campaignsite using AJAX request. I have set up a menu_callback item in my hook_menu, that checks if any $_POSTs are coming in, and it works if i make a form that has the action='http://mysite.com/menucallback/url', but i get nothing in response if i make the same request with ajax. I have access arguments set to 'access content'. If anyone knows what might be the problem, that would be very helpful. Thank you. /Anders

• What are some of the best answer file settings for a WDS Deployment?

  - by drpcken

  I've had my head buried in answer files for days now and have gotten quite comfortable setting them up, test, etc... I use a handful of Components to help my migrations, for my unattend.xml I like: Windows-International-Core-WinPE -- this is good for setting Locales the preboot environment (en-us for us english US speakers). Keeps me from having to set these on the initial image boot. Windows-Setup_neutral -- I like the WindowsDeploymentServices -> ImageSelection, especially if I'm only pushing a single image. This keeps me from having to select it each time. My OOBE_Unattend.xml is really useful and I barely have to touch anything during this part of the installation: Windows-Shell-Setup_neutral -- This lets me put a ProductKey in for my MAK volume license (very useful and time saving). I can also set the TimeZone for the installation. Windows UnattendedJoin_neutral -- I couldn't live without this component. It joins the machine on my domain before logging in as a domain administrator. I would hate to not have this ability. Windows-International-Core -- Again this component really speeds up the OOBE process. I configure my locals and time zone so I don't have to do it by hand when the machine enteres OOBE. Windows-Shell-Setup -- Allows you to configure an autologon when the new machine is finished. I like to logon as a domain admin automatically for customizing and troubleshooting the new machine immediately after it is imaged. Also the OOBE component under here lets me skip the EULA, Hide Wireless Setup, and set my default NetworkLocation. All of this makes the entire OOBE totally automated. What are some other good components I am missing as far as helping me get these images pushed and configured as quickly as possible?

• Codeigniter how to access class variables

  - by Obay

  I thought this was going to be a no-brainer but I can't seem to access member variables: class MyObject extends Controller { private $START_OF_WEEK = 1; /* constructor here */ function index() { echo $this->$START_OF_WEEK; } } echo $this->$START_OF_WEEK; says Cannot access empty property How do I access member variables? Or... how do I declare them correctly?

• Turn Function or Stored Procedure Result into "live" Result for LINQ

  - by Alex

  Is it possible to turn result sets obtained in LINQ through a stored procedure or function call into a "live" set of objects of which I can retrieve Foreign Key related objects? If, for example, my stored procedure returns a set of rows (= LINQ objects) of type "Contact", then I can't seem to obtain Contact.BillingAddress (which is related by Foreign Key). Any idea how to make this work?

• I get 2014 Cannot execute queries while other unbuffered queries are active when doing exec with PDO

  - by Itay Moav

  I am doing a PDO::exec command on multiple updates: $MyPdo->setAttribute(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY,true); $MyPdo->exec("update t1 set f1=1;update t2 set f1=2"); I am doing it inside a transaction, and I keep getting: SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute. those are the only query/ies

• How to remove not required Elements from generated XML via jaxb

  - by Dangling Piyush

  I want to know if there is anyway for removing not required elements from generated xml using jaxb.I have my xsd element definition as follows. <xsd:element name="Title" maxOccurs="1" minOccurs="0"> <xsd:annotation> <xsd:documentation> A name given to the digital record. </xsd:documentation> </xsd:annotation> <xsd:simpleType> <xsd:restriction base="xsd:string"> <xsd:minLength value="1"></xsd:minLength> </xsd:restriction> </xsd:simpleType> </xsd:element> As you can see it is not a mandatory element because minOccurs="0" But if it is not empty the length should be 1. <xsd:minLength value="1"></xsd:minLength> At the time of marshalling if I left the Title field blank it is throwing the SAXException because of min-length restriction. So what I want to do is to remove the whole occurrence of <Title/> from generated XML.Right now i have removed the min-length restriction so it is adding the <Title> element as EMPTY <Title></Title> But I do not want it like this.Any help is appreciated.I am using jaxb 2.0 for Marshalling. UPDATE: Following is my variable definiton : private JAXBContext jaxbContext; private Unmarshaller unmarshaller; private SchemaFactory factory; private Schema schema; private Marshaller marshaller; Marshalling code. jaxbContext = JAXBContext.newInstance(ERecordType.class); marshaller = jaxbContext.createMarshaller(); factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI); schema = factory.newSchema((new File(xsdLocation))); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); ERecordType e = new ERecordType(); e.setCataloging(rc); /** * Validate Against Schema. */ marshaller.setSchema(schema); /** * Marshal will throw an exception if XML not validated against * schema. */ marshaller.marshal(e, System.out);

• Connect Chrome to TOR

  - by Jack M

  I'm having difficulty connecting Chrome to TOR. I started trying yesterday. I started Vidalia and the TOR Browser and then followed the advice at http://lifehacker.com/5614732/create-a-tor-button-in-chrome-for-on+demand-anonymous-browsing - downloading Proxy Switchy and setting it up as stated. This resulted in Error 130 (net::ERR_PROXY_CONNECTION_FAILED) (in Chrome, when I tried to load a webpage). So I looked into Vidalia's settings and noticed that it appeared to be using port 9051, so I set that instead of 8118 as everyone on the internet seems to be suggesting. Then I got a new error: Error 111 (net::ERR_TUNNEL_CONNECTION_FAILED). Digging a bit, I found that Tor should be set as a SOCKS proxy, not an HTTP proxy, so I unticked "use same settings for all protocols" in Proxy Switchy and just set localhost:9051 for SOCKS. That got me Error 7 (net::ERR_TIMED_OUT). And that's when I came here for help. I typed up the above question, but then at the last minute decided to do a bit more reading and found someone here suggested using some command line arguments via a Windows shortcut: "C:\snip\chrome.exe" --proxy-server=";socks=127.0.0.1:9051;sock4=127.0.0.1:9051;sock5=127.0.0.1:9051" --incognito check.torproject.org And that worked perfectly. Yesterday. Today it doesn't, so I'm having to post this question after all. check.torproject.org gives me a "no" with Chrome, but a "yes" with the default Tor Browser. I tried closing Chrome and restarting it (yes, with the correct shortcut) after Vidalia started, but still nothing. The port number hasn't changed or anything. What gives? EDIT: I realized I had a "non tor" instance of Chrome running and that possibly the was causing the command line args t be ignored when I started the new instance. Closed all instances of chrome and ran my Chrome Tor shortcut, and it did get rid of the "not using Tor" message -- because I got another Time Out error instead. Vidalia's bandwidth graph didn't even blink.

• os.environ() giving errors while setting for Hudson

  - by Arnab Sen Gupta

  I want a small python script to set the HUDSON_HOME environment variable. When using the shell, I can easily do this using set HUDSON_HOME=http://localhost:8080 But how can I do the same directly through python?? I don't want to do it by passing the command line to os.system().. can os.environ() be of any help?? I had in my script: import os os.environ('HUDSON_HOME')='http://localhost:8080' but it's probably setting it for the subprocss and not the parent shell..any way around this??

• Vista Screen resolution Changes when Switching Users

  - by Benjol

  I regularly have a problem when switching between users in Vista - the screen resolution drops down to 800x600. If I try to set the resolution back to the maximum, it says nothing, but just keeps it at 800x600. I can set it back to an intermediate value. Otherwise I have to either restart the PC, or sometimes if I log off one of the users, I can then set the resolution back to max. Might it also have something to do with using sleep mode instead of performing regular shutdowns? I thought it might be related to the desktop background image taking up too much space, but even with plain colours, the problem still occurs. There is an enormous thread on this here, but not really any answers. From what I can gather from that thread, it isn't related to any particular applications, nor limited to a particular make of graphics card or monitor, so I don't think that including hardware details is useful. This is a very annoying problem, as it screws up my desktop and screen layout every single time. Has anyone here experienced this problem or found a solution? I've noticed that Windows Update has tried to install nVidia updates and apparently they've failed on several occasions. Not sure if that is of any relevance or not. UPDATE The last post on the thread: FWIW - I had this problem for about 2 years and wrote a number of posts in this thread in the past. It survived OS reinstallation, change of practically all of my hardware piece by piece (mobo, cpu, monitor, graphics card, memory, power supply...) I used to be affected by this annoying problem at least once every 24-48 hours. About 1.5 months ago I wiped out my 32 bit vista ultimate installation and installed Windows7 ultimate 64 bit from scratch and never saw this problem again. GOOD RIDDANCE. Vista was a pathetic piece of __ that felt like a flashback to the old [horrible] NT4/Windows95 days. I was seriously considering switching over to Apple/Mac OSX if this problem persisted.

• Tomcat session stickiness in session replication

  Hi, I am having a 2 instance load balanced and session replicated tomcat 6.0.20 cluster. Should sticky_session be set to true or false for in memory session replication. http://tomcat.apache.org/connectors-doc/reference/workers.html mentions : Set sticky_session to False when Tomcat is using a Session Manager which can persist session data across multiple instances of Tomcat. where as /tomcat-6.0-doc/cluster-howto.html (Cluster Basics) mentions : Make sure that your loadbalancer is configured for sticky session mode.

• How do I run my application as superuser from Eclipse?

  - by Ronald

  I'm running in to an error when I try to run my server application from Eclipse. The error is java.net.BindException: Permission denied. I think this is because I am using port 443 to set up an SSL connection. I can get around this problem if I run my code on the command line using javac and sudo. Is there a way to set up Eclipse so that when I hit the run button, my application is executed with sudo?

• How can I pass managed objects from one AppDomain to another?

  - by Dennis P

  I have two assemblies that I'm trying to link together. One is a sort of background process that's built with WinForms and will be designed to run as a Windows Service. I have a second project that will act as a UI for the background process whenever a user launches it. I've never tried attempting something like this with managed code before, so I've started trying to use windows messages to communicate between the two processes. I'm struggling when it comes to passing more than just IntPtrs back and forth, however. Here's the code from a control in my UI project that registers itself with the background process: public void Init() { IntPtr hwnd = IntPtr.Zero; Process[] ps = Process.GetProcessesByName("BGServiceApp"); Process mainProcess = null; if(ps == null || ps.GetLength(0) == 0) { mainProcess = LaunchApp(); } else { mainProcess = ps[0]; } SendMessage(mainProcess.MainWindowHandle, INIT_CONNECTION, this.Handle, IntPtr.Zero); } protected override void WndProc(ref Message m) { if(m.Msg == INIT_CONFIRMED && InitComplete != null) { string message = Marshal.PtrToStringAuto(m.WParam); Marshal.FreeHGlobal(m.WParam); InitComplete(message, EventArgs.Empty); } base.WndProc(ref m); } This is the code from the background process that's supposed to receive a request from the UI process to register for status updates and send a confirmation message. protected override void WndProc(ref Message m) { if(m.Msg == INIT_CONNECTION) { RegisterUIDispatcher(m.WParam); Respond(m.WParam); } if(m.Msg == UNINIT_CONNECTION) { UnregisterUIDispatcher(m.WParam); if(m_RegisteredDispatchers.Count == 0) { this.Close(); } } base.WndProc(ref m); } private void Respond(IntPtr caller) { string test = "Registration confirmed!"; IntPtr ptr = Marshal.StringToHGlobalAuto(test); SendMessage(caller, INIT_CONFIRMED, ptr, IntPtr.Zero); } } The UI process receives the INIT_CONFIRMED message from my background process, but when I try to marshal the IntPtr back into a string, I get an empty string. Is the area of heap I'm using out of scope to the other process or am I missing some security attribute maybe? Is there a better and cleaner way to go about something like this using an event driven model?

• How to update a table using a select group by in a second one as the data source in MySQL?

  - by Jader Dias

  I can't do this in MySQL UPDATE tableA, tableB SET tableA.column1 = SUM(tableB.column2) WHERE tableA.column3 = tableB.column4 GROUP BY tableB.column4 ; Neither can I UPDATE tableA, ( SELECT SUM(tableB.column2) sumB, tableB.column4 FROM tableB GROUP BY tableB.column4 ) t1 SET tableA.column1 = sumB WHERE tableA.column3 = column4 ; Besides it being illegal code, I think you can understand what I tried to do with the queries above. Both of them had the same intent. How can I do that in MySQL?

• Ctrl-Backspace Visual Studio 2010

  I recently upgraded to Visual Studio 2010 and found out that when i press Ctrl-Backspace on a empty line it will delete the line, which is what it did in 2008, but then it will also delete the last character on the line above. I have tried to see if there is any settings anywhere but i cant seem to find any. Does anyone know if you can change this or did they make it default in 2010 Im using C#, if that makes a difference.

• Too many concurrent connections Exchange 2010. What else is there to check?

  - by hydroparadise

  I thought that I had this under control before. But for some reason during our last email marketing promo, I start receiving from our mass email client (built in house).. The message could not be sent to the SMTP server. The transport error code is 0x800ccc67. The server repsonse was 421 4.3.2 The maximum number of concurrent connections has exceeded a limit, closing transmission channel again. There's several places I've checked to make sure that wouldn't be an issue. First I checked that receive connector was set to receive an adequate number of connections on our relay connector (1000 connections). Then, I would later find out about Throttling Policies. I created one and set all the properties I knew to set in terms of the policy following properties to 1000; EWSMaxConcurrency, OWAMaxConcurrency, CPAMaxConcurrency, and CPAMaxConcurrency. Still, the email client starts receiving the error shortly after 100 has been sent and takes about 15-30 seconds. The process is then repeatable, but still the error gets received at the same spot everytime. Is there a rate setting that I am missing? Was there a windows update that I missed looking at? Should the software have it's own throttling feature?

• Autocomplete server-side implementation

  - by toluju

  What is a fast and efficient way to implement the server-side component for an autocomplete feature in an html input box? I am writing a service to autocomplete user queries in our web interface's main search box, and the completions are displayed in an ajax-powered dropdown. The data we are running queries against is simply a large table of concepts our system knows about, which matches roughly with the set of wikipedia page titles. For this service obviously speed is of utmost importance, as responsiveness of the web page is important to the user experience. The current implementation simply loads all concepts into memory in a sorted set, and performs a simple log(n) lookup on a user keystroke. The tailset is then used to provide additional matches beyond the closest match. The problem with this solution is that it does not scale. It currently is running up against the VM heap space limit (I've set -Xmx2g, which is about the most we can push on our 32 bit machines), and this prevents us from expanding our concept table or adding more functionality. Switching to 64-bit VMs on machines with more memory isn't an immediate option. I've been hesitant to start working on a disk-based solution as I am concerned that disk seek time will kill performance. Are there possible solutions that will let me scale better, either entirely in memory or with some fast disk-backed implementations? Edits: @Gandalf: For our use case it is important the the autocompletion is comprehensive and isn't just extra help for the user. As for what we are completing, it is a list of concept-type pairs. For example, possible entries are [("Microsoft", "Software Company"), ("Jeff Atwood", "Programmer"), ("StackOverflow.com", "Website")]. We are using Lucene for the full search once a user selects an item from the autocomplete list, but I am not yet sure Lucene would work well for the autocomplete itself. @Glen: No databases are being used here. When I'm talking about a table I just mean the structured representation of my data. @Jason Day: My original implementation to this problem was to use a Trie, but the memory bloat with that was actually worse than the sorted set due to needing a large number of object references. I'll read on the ternary search trees to see if it could be of use.
