• Iterating changes using jQuery?

  - by HipHop-opatamus

  In the HTML below, I would like to copy the "submittedby" beside "message", within the H2 tag: <div class="comment"> <H2 class="threadtitle">Message 1</h2> <span class="submittedby">James</a> </div> <div class="comment"> <H2 class="threadtitle">Message 2</h2> <span class="submittedby">Bill</a> </div> <div class="comment"> <H2 class="threadtitle">Message 3</h2> <div class="submittedby">Phil</a> </div> My current jQuery code is as follows: $(document).ready(function() { $('.submittedby').copy().appendTo('.threadtitle'); }); The problem is this copies EVERY "submittedby" to EVERY "threadtitle". How do I code it so it only copies the "submittedby" from within the same "comment" div? Thanks!

• Cloud Agnostic Architecture?

  - by Dave

  Hi, I'm doing some architecture work on a new solution which will initially run in Windows Azure. However I'd like the solution (or at least the architecture/design) to be Cloud Agnostic (to whatever extent is realistic). Has anyone done any work on this front or seen any good white papers/blog posts? Our highlevel architecture will consist of a payload being sent to a web service (WCF for instance), this will be dumped on a queue (for arguments sake) and a worker process will grab messages off this queue and proccess them. There will be a database of customer information which we'd ideally like to keep out of the cloud however there are obvious performance considerations. Keen to hear other's thoughts. Cheers Dave

• How to remove animation glitch ?

  - by hib

  Hi all , I am downloading and then parsing some data on separate thread and then updating my ui on main thread with the following code but in this scenario I am getting animation "glitch" . I have read this word somewhere . - (void)didFinishParsing2:(NSArray *)appList { [self performSelectorOnMainThread:@selector(handleLoadedApps2:) withObject:appList waitUntilDone:NO]; self.queue = nil; // we are finished with the queue and our ParseOperation } - (void)handleLoadedApps2:(NSArray *)loadedApps{ [activityLabel removeFromSuperview]; self.controller.MyArray = (MyClass *)[arrMyArray objectAtIndex:0]; [[MySharedClass sharedSource].detailSource setObject:self.controller.MyArray forKey:someObject]; self.controller.hidesBottomBarWhenPushed = YES; isPushed = YES; [[self navigationController] pushViewController:self.controller animated:YES]; } Can anyone tell me what I am doing wrong so that I can remove the animation glitch .

• UIImage imageNamed not autoreleasing correctly

  - by MrHen

  For some reason, the retain/release behavior in the following code has me completely baffled. selectedImage = [UIImage imageNamed:@"icon_72.png"]; [selectedImage release]; This should break but does not. Why? I thought imageNamed autoreleased itself which means the release here is redundant and should break when the autorelease occurs. Here are snippets relevant to selectedImage from the .h and .m files: @property (nonatomic, readonly) UIImage *selectedImage; @synthesize delegate, selectedImage, spacerBottom, currentIndex; Other notes, this does break: selectedImage = [UIImage imageNamed:@"icon_72.png"]; [selectedImage release]; [selectedImage release]; //objc[55541]: FREED(id): message release sent to freed object=0x59245b0 //Program received signal: “EXC_BAD_INSTRUCTION”. As does this: selectedImage = [UIImage imageNamed:@"icon_72.png"]; [selectedImage release]; [selectedImage autorelease]; //objc[55403]: FREED(id): message autorelease sent to freed object=0x59b54c0 //Program received signal: “EXC_BAD_INSTRUCTION”. And so does the following: selectedImage = [UIImage imageNamed:@"icon_72.png"]; [selectedImage autorelease]; [selectedImage release]; //objc[55264]: FREED(id): message release sent to freed object=0x592c9a0 //Program received signal: “EXC_BAD_INSTRUCTION”. And so does this: selectedImage = [UIImage imageNamed:@"icon_72.png"]; [selectedImage autorelease]; [selectedImage autorelease]; //objc[55635]: FREED(id): message release sent to freed object=0x5b305d0 //Program received signal: “EXC_BAD_INSTRUCTION”.

As suggested in this question, I'm using the following Procmail config: :0: |$HOME/process_mail.py My process_mail.py script is receiving an email via stdin like this: From hostname Tue Jun 15 21:43:30 2010 Received: (qmail 8580 invoked from network); 15 Jun 2010 21:43:22 -0400 Received: from mail-fx0-f44.google.com (209.85.161.44) by ip-73-187-35-131.ip.secureserver.net with SMTP; 15 Jun 2010 21:43:22 -0400 Received: by fxm19 with SMTP id 19so170709fxm.3 for <[email protected]>; Tue, 15 Jun 2010 18:47:33 -0700 (PDT) MIME-Version: 1.0 Received: by 10.103.84.1 with SMTP id m1mr2774225mul.26.1276652853684; Tue, 15 Jun 2010 18:47:33 -0700 (PDT) Received: by 10.123.143.4 with HTTP; Tue, 15 Jun 2010 18:47:33 -0700 (PDT) Date: Tue, 15 Jun 2010 20:47:33 -0500 Message-ID: <[email protected]> Subject: TEST 12 From: Full Name <[email protected]> To: [email protected] Content-Type: text/plain; charset=ISO-8859-1 ONE TWO THREE I'm trying to parse the message in this way: >>> import email >>> msg = email.message_from_string(full_message) I want to get message fields like 'From', 'To' and 'Subject'.

• How to use wildcards and variable substitution in activemq camel routes

  - by sicotron

  I would like to set up a generic camel route that routes all messages to a set of queues to a queue with the same name and a suffix. I'm thinking it would look something like this: <camelContext id="camel" trace="false" xmlns="http://camel.apache.org/schema/spring"> <route id="genericRoute"> <from uri="activemq:queue:somequeues.*" /> <to uri="${getMyQueueName}.moo" /> </route> </camelContext> activemq talks about wildcards here: http://activemq.apache.org/wildcards.html but nothing more that I can find. This may not even be possible but would be very handy if it is! Thanks,

• Javascript error: Object required...tough time fixing this

  - by rtnav2301

  The situation is this: a friend of mine asked me to help her with a website she's working on called www.KeepsakePartyInvitations.com. Her original designer created this code but didn't finish the project. So here I am to help save the day. Now, once a photo has been added to the party template and the mouse is placed over the image, an alternate text message appears to the right. The message informs the visitor how to reposition and resize the image, if necessary. I'm testing the procedure in the invitation to reposition the image. I follow the directions about moving the picture, but the mouse does not let go of the photo. Where ever the mouse moves, so does the image. The same thing occurs if you want to resize the image, you follow the directions but the image does not resize. I check the error message in IE 8 and it states: Message: Object required Line: 873 Char: 3 Code: 0 URI: http://www.keepsakepartyinvitations.com/Includes/JCode.js When I checked the Javascript file, the Line 873 states: tempX = e.clientX + document.body.scrollLeft If you review the javascript file, the function where the line is located is called: function getMouseXY(e). Please help me, it has been a long while since I've worked with Javascript and I'm motivated to get this fixed. Thank you!

• Using Dijkstra's algorithm with negative edges?

  - by Riddler

  Most books explain the reason the algorithm doesn't work with negative edges as nodes are deleted from the priority queue after the node is arrived at since the algorithm assumes the shortest distance has been found. However since negative edges can reduce the distance, a future shorter distance might be found; but since the node is deleted it cannot be updated. Wouldn't an obvious solution to this be to not delete the node? Why not keep the node in the queue, so if a future shorter distance is found, it can be updated? If I am misunderstanding the problem, what is preventing the algorithm from being used with negative edges?

• MSMQ.MSMQQueueInfo PathName Not Accepted

  - by user357596

  I am using MSMQ.MSMQQueueInfo with jscript on Windows 7 (the latest MSMQ version). This is being run on a domain joined computer. For some reason unknown to me, it just will not accept the PathName I give it (which is in an acceptable format). Here is the code: var qi = new ActiveXObject ("MSMQ.MSMQQueueInfo"); qi.PathName = "FormatName:Direct=OS:mycomputer\\Private$\\myqueue"; I know this PathName works, because I use the exact same path in c#, and that works: queue = new MessageQueue("FormatName:DIRECT=OS:" + contollerName + "\\Private$\\" + queueName); When the code "qi.Open()" in the jscript code attempts to execute, it returns this error message: The queue path name specified is invalid. Has anyone else run into this? Ideas? Comments? Suggestions? Thank you in advance!

• Why is there unreachable code here?

  - by Richard

  I am writing a c# app and want to output error messages to either the console or a messagebox (Depending on the app type: enum AppTypeChoice { Console, Windows } ), and also control wether the app keeps running or not ( bool StopOnError ). I came up with this method that will check all the criteria, but I'm getting an "unreachable code detected" warning. I can't see why! Here is the whole method (Brace yourselves for some hobbyist code!) public void OutputError(string message) { string standardMessage = "Something went WRONG!. [ But I'm not telling you what! ]"; string defaultMsgBoxTitle = "Aaaaarrrggggggggggg!!!!!"; string dosBoxOutput = "\n\n*** " + defaultMsgBoxTitle + " *** \n\n Message was: '" + message + "'\n\n"; AppTypeChoice appType = DataDefs.AppType; DebugLevelChoice level = DataDefs.DebugLevel; // Decide how much info we should give out here... if (level != DebugLevelChoice.None) { // Give some info.... if (appType == AppTypeChoice.Windows) MessageBox.Show(message, defaultMsgBoxTitle, MessageBoxButtons.OK, MessageBoxIcon.Error); else Console.WriteLine(dosBoxOutput); } else { // Be very secretive... if (appType == AppTypeChoice.Windows) MessageBox.Show(standardMessage, defaultMsgBoxTitle, MessageBoxButtons.OK, MessageBoxIcon.Error); else Console.WriteLine(standardMessage); } // Decide if app falls over or not.. if (DataDefs.StopOnError == true) Environment.Exit(0); // UNREACHABLE CODE HERE } Also, while I have your attention, to get the app type, I'm just using a constant at the top of the file (ie. AppTypeChoice.Console in a Console app etc) - is there a better way of doing this (i mean finding out in code if it is a DOS or Windows app)? Also, I noticed that I can use a messagebox with a fully-qualified path in a Console app...How bad is is to do that ( I mean, will I get tarred and feathered when other developers see it?!) Thanks for your help

• Email not sent until application closes

  - by Tester101

  I have an application that uses SmtpClient to send E-Mail, but the E-Mails are not sent until the application closes. I have searched and searched to find a solution to the problem, but I am not able to find one. The system does have Symantec anti-virus installed, which could possibly be the problem. Does anybody have a solution to this problem? Here is the code I am using. public class EMail { private string server; public string Server {get{return this.server;}set{this.server = value;}} private string to; public string To {get{return this.to;}set{this.to = value;}} private string from; public string From {get{return this.from;}set{this.from = value;}} private string subject; public string Subject {get{return this.subject;}set{this.subject = value;}} private string body; public string Body {get{return this.body;}set{this.body = value;}} public EMail() {} public EMail(string _server, string _to, string _from, string _subject, string _body) { this.Server = _server; this.To = _to; this.From = _from; this.Subject = _subject; this.Body = _body; } public void Send() { System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(this.From, this.To, this.Subject, this.Body); message.IsBodyHtml = true; System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient(this.Server); client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; //I have tried this, but it still does not work. //client.ServicePoint.ConnectionLeaseTimeout = 0; try { client.Send(message); } catch(System.Exception ex) { System.Windows.Forms.MessageBox.Show(ex.ToString()); } message.Dispose(); } }

• How to add text to email sent from a php contact form

  - by JustStatic

  Hi all this is the PHP im using: <?php $name = $_POST['name']; $email = $_POST['email']; $phone = $_POST['phone']; $message = $_POST['message']; $formcontent=" From: $name \n Phone: $phone \n Message: $message"; $recipient = "[email protected]"; $subject = "Contact Form"; $mailheader = "From: $email \r\n"; mail($recipient, $subject, $formcontent, $mailheader) or die("Error!"); echo "Thank You!" . " -" . "<a href='contact.html' style='text-decoration:none; color:#ff0099;'> Return Home</a>"; ?> Its working perfectly fine but i would like there to be some text sent with this email that says "This is from your website" or something similar to tell the recipient that it isnt spam (my client isn't tech friendly and sees everything plain text as spam). I'm very new to PHP with nearly 0 knowledge and have no idea how to add something like that. I did have a go at making a new variable with the string inside and then include that in the: mail($recipient, $subject, $formcontent, $mailheader) or die("Error!"); line but with no success. Thanks for taking the time any help would be welcome.

• A Question about using jython when run a receving socket in python

  - by abusemind

  Hi, I have not a lot of knowledge of python and network programming. Currently I am trying to implement a simple application which can receive a text message sent by the user, fetch some information from the google search api, and return the results via text message to the user. This application will continue to listening to the users messages and reply immediately. How I get the text short message sent by the user? It's a program named fetion from the mobile supplier in China. The client side fetion, just like a instant communication tool, can send/receive messages to/from other people who are using mobile to receive/send SMS. I am using a open source python program that simulates the fetion program. So basically I can use this python program to communate with others who using cell phone via SMS. My core program is based on java, so I need to take this python program into java environment. I am using jython, and now I am available to send messages to users by some lines of java codes. But the real question is the process of receving from users via SMS. In python code, a new thread is created to continuously listen to the user. It should be OK in Python, but when I run the similar process in Jython, the following exception occurs: Exception in thread Thread:Traceback (most recent call last): File "D:\jython2.5.1\Lib\threading.py", line 178, in _Thread__bootstrap self.run() File "<iostream>", line 1389, in run File "<iostream>", line 1207, in receive File "<iostream>", line 1207, in receive File "<iostream>", line 150, in recv File "D:\jython2.5.1\Lib\select.py", line 223, in native_select pobj.register(fd, POLLIN) File "D:\jython2.5.1\Lib\select.py", line 104, in register raise _map_exception(jlx) error: (20000, 'socket must be in non-blocking mode') The line 150 in the python code is as follows: def recv(self,timeout=False): if self.login_type == "HTTP": time.sleep(10) return self.get_offline_msg() pass else: if timeout: infd,outfd,errfd = select([self.__sock,],[],[],timeout)//<---line 150 here else: infd,outfd,errfd = select([self.__sock,],[],[]) if len(infd) != 0: ret = self.__tcp_recv() num = len(ret) d_print(('num',),locals()) if num == 0: return ret if num == 1: return ret[0] for r in ret: self.queue.put(r) d_print(('r',),locals()) if not self.queue.empty(): return self.queue.get() else: return "TimeOut" Because of I am not very familiar with python, especially the socket part, and also new in Jython use, I really need your help or only advice or explanation. Thank you very much!

  Hello I have a Biztalk 2006 R2 project (used with ESB Guidance 1) I am calling from orchstration to a static method in c# code, this method uses a class to load a file data into xlang message body at part 0 When i pass filepath which doesnt exists the inside class catch the exception but dont throw it up (in the static method there is a catch block and in the orchstration there is the real handling of the exception) The static method is : public static XLANGMessage LoadFileIntoMessage(XLANGMessage message, string filePath,Encoding encoding) { try { IStreamFactory sf = new FileStreamFactory(filePath,encoding); message[0].LoadFrom(sf); return message; } catch (Exception ex) { throw ex; } } The Class which load the file stream is : private class FileStreamFactory : IStreamFactory { string _fname; Encoding _encoding; public FileStreamFactory(string fname,Encoding encoding) { _fname = fname; _encoding = encoding; } public Stream CreateStream() { try { StreamReader sr; sr = new StreamReader ( _fname, _encoding ); return sr.BaseStream; } catch (Exception ex) { throw ex; } } } I call the static method from the orchstration and expect to catch the exception in my orchstration after the class and the emthod gets it

• sizeof continues to return 4 instead of actual size

I type seven letters but only four integers are printed. The loop only occurs four times on my computer, not the number of characters in the string.

• C# Is it possible to interrupt a specific thread inside a ThreadPool?

  - by Lirik

  Suppose that I've queued a work item in a ThreadPool, but the work item blocks if there is no data to process (reading from a BlockingQueue). If the queue is empty and there will be no more work going into the queue, then I must call the Thread.Interrupt method if I want to interrupt the blocking task, but how does one do the same thing with a ThreadPool? The code might look like this: void Run() { try { while(true) { blockingQueue.Dequeue(); doSomething(); } } finally { countDownLatch.Signal(); } } I'm aware that the best thing to do in this situation is use a regular Thread, but I'm wondering if there is a ThreadPool equivalent way to interrupt a work item.

• How to get user input before saving a file in Sublime Text

  - by EddieJessup

  I'm making a plugin in Sublime Text that prompts the user for a password to encrypt a file before it's saved. There's a hook in the API that's executed before a save is executed, so my naïve implementation is: class TranscryptEventListener(sublime_plugin.EventListener): def on_pre_save(self, view): # If document is set to encode on save if view.settings().get('ON_SAVE'): self.view = view # Prompt user for password message = "Create a Password:" view.window().show_input_panel(message, "", self.on_done, None, None) def on_done(self, password): self.view.run_command("encode", {password": password}) The problem with this is, by the time the input panel appears for the user to enter their password, the document has already been saved (despite the trigger being 'on_pre_save'). Then once the user hits enter, the document is encrypted fine, but the situation is that there's a saved plaintext file, and a modified buffer filled with the encrypted text. So I need to make Sublime Text wait until the user's input the password before carrying out the save. Is there a way to do this? At the moment I'm just manually re-saving once the encryption has been done: def on_pre_save(self, view, encode=False): if view.settings().get('ON_SAVE') and not view.settings().get('ENCODED'): self.view = view message = "Create a Password:" view.window().show_input_panel(message, "", self.on_done, None, None) def on_done(self, password): self.view.run_command("encode", {password": password}) self.view.settings().set('ENCODED', True) self.view.run_command('save') self.view.settings().set('ENCODED', False) but this is messy and if the user cancels the encryption then the plaintext file gets saved, which isn't ideal. Any thoughts? Edit: I think I could do it cleanly by overriding the default save command. I hoped to do this by using the on_text_command or on_window_command triggers, but it seems that the save command doesn't trigger either of these (maybe it's an application command? But there's no on_application_command). Is there just no way to override the save function?

• Problem with Restlet on GAE

  - by Leaf

  I'm trying to implement a calculator web service on GAE using Java Restlets... it works perfectly fine on localhost but when I upload my project to the Google App Engine everytime I try the web service link it says the link is broken. Here's the code I used: public Restlet createInboundRoot() { // Create a router Restlet that routes each call to a // new instance of HelloWorldResource. Router router = new Router(getContext()); Restlet restlet = new Restlet() { public void handle(Request request, Response response) { // Print the requested URI path String parameters = request.getResourceRef().getRemainingPart(); String message; if(parameters.charAt(0)=='?'){ message = "" + Calculator.calculate(parameters.substring(1)); } else { message = ""; } response.setEntity(message, MediaType.TEXT_PLAIN); } }; // Defines only one route router.attachDefault(restlet); return router; } The Application it's on is mapped to the /calcservice but as I said when I upload to GAE it comes back with a broken link error. I'm developing on Eclipse 3.4 and I'm wondering if there are any parameters I have to change to include the Restlet classes.

  I have an Ajax contact form that links to a jquery file but for some reason I get the following error in Firebug: $("#contactform").submit is not a function Here is the link to the jquery file: <script type="text/javascript" src="scripts/jquery.jigowatt.js"></script> Here is the jquery code: jQuery(document).ready(function(){ $('#contactform').submit(function(){ var action = $(this).attr('action'); $("#message").slideUp(750,function() { $('#message').hide(); $('#submit') .after('<img src="assets/ajax-loader.gif" class="loader" />') .attr('disabled','disabled'); $.post(action, { name: $('#name').val(), company: $('#company').val(), email: $('#email').val(), phone: $('#phone').val(), subject: $('#purpose').val(), comments: $('#comments').val(), verify: $('#verify').val() }, function(data){ document.getElementById('message').innerHTML = data; $('#message').slideDown('slow'); $('#contactform img.loader').fadeOut('slow',function() {$(this).remove()}); $('#contactform #submit').attr('disabled',''); if(data.match('success') != null) $('#contactform').slideUp('slow'); } ); }); return false; }); }); And last but not least, here is the page where it is all supposed to come together: http://theideapeople.com.previewdns.com/contact_us.html I would appreciate some help getting the function to function properly. Thanks.

• XMPP4R Callbacks dont seem to work

  - by Sid

  Im using xmpp4r and trying to get the hang of a basic chat feature that I wish to implement later in my Rails app. My fundamentals on Ruby Threads is still a bit shaky so I would appreciate any help on this. Though I register the callback i dont get a response from my gmail account. I am able to send a message but my ruby program terminates. In order to prevent it from terminating I tried to stop on of the threads in the program but I cant seem to get it working. require 'rubygems' require "xmpp4r/client" require "xmpp4r/roster" include Jabber def connect client = Client.new(JID::new("[email protected]")) client.connect client.auth("test") client.send(Presence.new.set_type(:available)) client end def create_message(message, to_email) msg = Jabber::Message::new(to_email, message) msg.type = :chat msg end def subscribe(email_id) pres = Presence.new.set_type(:subscribe).set_to(email_id) pres end client = connect roster = Roster::Helper.new(client) roster.add_subscription_request_callback do |item,pres| roster.accept_subscription(pres.from) end def create_callback(client) $t4= Thread.new do client.add_message_callback do |m| puts m.body puts "................................Callback working" end end end puts "Client has connected" msg = create_message("Welcome to the winter of my discontent", "[email protected]") client.send(msg) create_callback(client) def check(client) $t3 = Thread.new do loop do puts "t3 still running........." Thread.current.stop $t4.join end end end check(client)

• RSA_sign and RSACryptoProvider.VerifySignature

  - by Miky D

  I'm trying to get up to speed on how to get some code that uses OpenSSL for cryptography, to play nice with another program that I'm writing in C#, using the Microsoft cryptography providers available in .NET. More to the point, I'm trying to have the C# program verify an RSA message signature generated by the OpenSSL code. The code that generates the signature looks something like this: // Code in C, using the OpenSSL RSA implementation char msgToSign[] = "Hello World"; // the message to be signed char signature[RSA_size(rsa)]; // buffer that will hold signature int slen = 0; // will contain signature size // rsa is an OpenSSL RSA context, that's loaded with the public/private key pair memset(signature, 0, sizeof(signature)); RSA_sign(NID_sha1 , (unsigned char*)msgToSign , strlen(msgToSign) , signature , &slen , rsa); // now signature contains the message signature // and can be verified using the RSA_verify counterpart // .. I would like to verify the signature in C# In C#, I would do the following: import the other side's public key into an RSACryptoServiceProvider object receive the message and it's signature try to verify the signature I've got the first two parts working (I've verified that the public key is loading properly because I managed to send an RSA encrypted text from the C# code to the OpenSSL code in C and successfully have it decrypted) In order to verify the signature in C#, I've tried using the: VerifySignature method of the RSACryptoServiceProvider but that didn't work. And digging around the internet I was only able to find some vague information pointing out that .NET uses a different method for generating the signature than OpenSSL does. So, does anybody know how to accomplish this?
