    I'm using xpath in Selenium RC via the Python api.

  • How to get Netty websocket client example working

    - by Paul Butcher
    I'm struggling to get the netty example websocket client working. I've compiled successfully with 4.0.0.Alpha8, but when I try to connect to a server (also a netty example) I get: Exception in thread "main" io.netty.handler.codec.http.websocketx.WebSocketHandshakeException: Invalid handshake response upgrade: websocket at io.netty.handler.codec.http.websocketx.WebSocketClientHandshaker13.finishHandshake(WebSocketClientHandshaker13.java:204) which makes no sense to me whatsoever, given that this piece of code reads: String upgrade = response.getHeader(Names.UPGRADE); if (!Values.WEBSOCKET.equalsIgnoreCase(upgrade)) { throw new WebSocketHandshakeException("Invalid handshake response upgrade: " + response.getHeader(Names.UPGRADE)); } And as the message in the exception demonstrates, the Upgrade header does contain websocket as expected. Any idea what's going on?

  • Retrieve Table Row Index of Current Row

    - by Jon
    Hi Everyone, I am trying to validate a text input when it loses focus. I would like to know which row of the table it is in. This is what I have so far and it keeps coming back as undefined. Any ideas? $("div#step-2 fieldset table tbody tr td input").blur(function() { var tableRow = $(this).parent().parent(); if ($.trim($(this).val()) == "") { $(this).addClass("invalid"); alert(tableRow.rowIndex); $(this).val(""); } else { $(this).removeClass("invalid"); checkTextChanges(); } });

  • adding model validation errors in rescue

    - by ash34
    I have the following model with a virtual attribute class Mytimeperiod < ActiveRecord::Base validates presence of :from_dt validates_format_of :from_dt, :with => /\A\d{2}\/\d{2}\/\d{4}\Z/, :message => "format is mm/dd/yyyy" def from_dt self.from_date.strftime("%m/%d/%Y") if !self.from_date.blank? end def from_dt=(from_dt) self.from_date = Date.parse(from_dt) rescue self.errors.add_to_base("invalid from dt") end end I am using <%= f.error_messages %> to display the error messages on the form. I am using from_dt as a virtual attribute (string). The 'presence of' and 'format of' validation errors show up on the form, but when the user enters an invalid date format on the form and Date.Parse raises an exception I have a 'errors.add_to_base' statement in the rescue clause. Can anyone tell me why this error does not show up in the form error messages when I disable the 'format of' validation. thanks.

  • Edit Distance in Python

    - by Alice
    I'm programming a spellcheck program in Python. I have a list of valid words (the dictionary) and I need to output a list of words from this dictionary that have an edit distance of 2 from a given invalid word. I know I need to start by generating a list with an edit distance of one from the invalid word(and then run that again on all the generated words). I have three methods, inserts(...), deletions(...) and changes(...) that should output a list of words with an edit distance of 1, where inserts outputs all valid words with one more letter than the given word, deletions outputs all valid words with one less letter, and changes outputs all valid words with one different letter. I've checked a bunch of places but I can't seem to find an algorithm that describes this process. All the ideas I've come up with involve looping through the dictionary list multiple times, which would be extremely time consuming. If anyone could offer some insight, I'd be extremely grateful. Thanks!

  • Error processing response in .net web service with WSE3 mutualCertificate10Security Assertion

    - by Maeloc
    I am securing a .net web service (framework 2.0) with WSE3 mutualCertificate10Security Assertion. When request are valid all is fine and the response is wellformed, but when the request is invalid (cause a invalid signature, failed check, or soapexception thrown), the web server isn't able to process the response to send to the client. The error in application event log is: An error occured processing an outgoing fault response. Details of the error causing the processing failure: System.InvalidOperationException: Send security filter on the server could not retrieve the operation protection requirements from the operation state. en Microsoft.Web.Services3.Security.SecureConversationServiceSendSecurityFilter.SecureMessage(SoapEnvelope envelope, Security security) en Microsoft.Web.Services3.Security.SendSecurityFilter.ProcessMessage(SoapEnvelope envelope) en Microsoft.Web.Services3.Pipeline.ProcessOutputMessage(SoapEnvelope envelope) en Microsoft.Web.Services3.WseProtocol.GetFilteredResponseEnvelope(SoapEnvelope outputEnvelope) All certificate permissions are OK (when request is OK the web service is able to sign the response). Error occurs only if a soapFault must be returned in the response. Any ideas?

  • Raw socket sendto() failure in OS X

    - by user37278
    When I open a raw socket is OS X, construct my own udp packet (headers and data), and call sendto(), I get the error "Invalid Argument". Here is a sample program "rawudp.c" from the web site http://www.tenouk.com/Module43a.html that demonstrates this problem. The program (after adding string and stdlib #includes) runs under Fedora 10 but fails with "Invalid Argument" under OS X. Can anyone suggest why this fails in OS X? I have looked and looked and looked at the sendto() call, but all the parameters look good. I'm running the code as root, etc. Is there perhaps a kernel setting that prevents even uid 0 executables from sending packets through raw sockets in OS X Snow Leopard? Thanks.

  • What are the rules for Javascript's automatic semicolon insertion?

    - by T.R.
    Well, first I should probably ask if this is browser dependent. I've read that if an invalid token is found, but the section of code is valid until that invalid token, a semicolon is inserted before the token if it is preceded by a line break. However, the common example cited for bugs caused by semicolon insertion is: return _a+b; which doesn't seem to follow this rule, since _a would be a valid token. On the other hand, breaking up call chains works as expected: $('#myButton') .click(function(){alert("Hello!")}); Does anyone have a more in-depth description of the rules?

  • Custom certificate as proof of transaction

    - by Andy
    I'm developing a site where a user conducts a given transaction and once completed, the user is issued with a 'secure certificate'. The certificate serves as proof of the transaction and the user is able to upload the certificate at a later stage, to view the details of the transaction. At the moment I'm using a custom XML document with encrypted fields. It works perfect, but I would like a standardized approach, such as an X.509 certificate. I'm no encryption expert, but from what I gather, X.509 is more geared towards SSL issued by a CA. Is it possible to create your own valid valid CRT file? As a test, I created a CRT file with the example provided on WikiPedia. However, when I open the file in Windows I get this warning: Invalid Public Key Security Object File - This file is invalid as the following: Security Certificate. Not having much luck here, so time to ask the experts. What direction should I be heading in? Any guidance would be greatly appreciated.

  • Some unclear PHP syntax

    - by serhio
    I am a PHP beginner and saw on the forum this PHP expression: $regex = <<<'END' / ( [\x00-\x7F] # single-byte sequences 0xxxxxxx | [\xC0-\xDF][\x80-\xBF] # double-byte sequences 110xxxxx 10xxxxxx | [\xE0-\xEF][\x80-\xBF]{2} # triple-byte sequences 1110xxxx 10xxxxxx * 2 | [\xF0-\xF7][\x80-\xBF]{3} # quadruple-byte sequence 11110xxx 10xxxxxx * 3 ) | ( [\x80-\xBF] ) # invalid byte in range 10000000 - 10111111 | ( [\xC0-\xFF] ) # invalid byte in range 11000000 - 11111111 /x END; Is this code correct? What do these strange (for me) constructions like <<<, 'END', /, /x, and END; mean? I recieve: Parse error: syntax error, unexpected T_SL in /home/vhosts/mysite.com/public_html/mypage.php on line X Thanks

  • Programmatically adding a trusted cert in Java

    - by directedition
    I use SSL to communicate between two components written in Java. I can't use a CA, so I have to self-sign everything. Unfortunately, this means that when I try to handshake, I get a SunCertPathBuilderException. I can create my own X509TrustManager that just trusts everything, but that sort of defeats the purpose of having a signed cert. I would like, when first making the connection, to prompt the user with "SSL handshake with invalid cert. Add cert to store?" or something so they could have it added for them to their certificate store, like web browsers do at sites with invalid certs. I can find plenty of examples online of adding a cert to the store through the commandline, but I can't figure out how to do it programmatically. Is there a way to do this?

  • Using HTTP status codes to reflect success/failure of Web service request?

    - by jgarbers
    I'm implementing a Web service that returns a JSON-encoded payload. If the service call fails -- say, due to invalid parameters -- a JSON-encoded error is returned. I'm unsure, however, what HTTP status code should be returned in that situation. On one hand, it seems like HTTP status codes are for HTTP: even though an application error is being returned, the HTTP transfer itself was successful, suggesting a 200 OK response. On the other hand, a RESTful approach would seem to suggest that if the caller is attempting to post to a resource, and the JSON parameters of the request are invalid somehow, that a 400 Bad Request is appropriate. I'm using Prototype on the client side, which has a nice mechanism for automatically dispatching to different callbacks based on HTTP status code (onSuccess and onFailure), so I'm tempted to use status codes to indicate service success or failure, but I'd be interested to hear if anyone has opinions or experience with common practice in this matter. Thanks!

  • Fluent NHibernate MappingException : could not instantiate id generator

    - by Mark Simpson
    I'm pottering around with Fluent NHibernate to try and get a simple app up and running. I'm running through this Fluent NHibernate Tutorial. Everything seems to be going fine and I've created the required classes etc. and it all builds, but when I run the test, I get an exception. Someone in the comments section of the tutorial has the same problem, but I can't find any good information on what's causing it. Any help appreciated. It's probably something trivial. Exception details: FluentNHTest.Tests.Mappings.CustomerMappingTests.ValidateMappings: FluentNHibernate.Cfg.FluentConfigurationException : An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail. ---- FluentNHibernate.Cfg.FluentConfigurationException : An invalid or incomplete configuration was used while creating a SessionFactory.

  • DataAnnotationsModelBinder with MVC2 RTM

    - by yang
    Trying to validate models with DataAnnotations but DefaulModelBinder overrides my Required property error messages and never uses my error messages for invalid data entry. Always show 'value' is invalid for 'property name'. In another question I saw that MVC 2 uses DefaultModelBinder but I couldn't find any class in MVC 2 binaries. I downloaded the source for MVC futures and changed some source to compile it for .Net 4.0 but although I had success to compile, it has compatability problems and doesn't work as expected. Any help is aprreciated.

  • Letting a new PHP page know a new POST value is an Array?

    - by Wintermute
    I have a page that creates an associative array, then passes it as a hidden value to a new PHP page. I have a foreach loop waiting to iterate through it but it coughs up an "invalid argument" error, as if the page doesn't know the value it's working with is an array (Despite "print" showing simply "Array"). This is essentially what I have: //Hidden input to be passed to the next page print "<input type=\"hidden\" name=\"price_list\" value=\"$item_list\"> //Code on the second page for the foreach loop extract($_POST); foreach($price_list as $name=>$price) { ... } But I am simply given "Warning: Invalid argument supplied for foreach() in /home/cut/mg299/public_html/PHP/invoice.php on line 17". The array works fine, as I can iterate on the previous page, and other values are parsed fine to this second page. Do I need to 'reinitialise' this array value?

  • Squeak - SUnit Testing for Errors

    - by Artium
    I have been suggested to use should:rise in my test case to test for errors that a method might raise. For some reason it does not work as axpected, so I want to verify that I'm doing it right. Here is the code in the test case: self should: [aMyClass compareTo: 'This is a string'] raise: 'invalid input'. My compareTo/1 method looks like this: (aMyClass isKindOf: MyClass) ifFalse: [self error: 'invalid input'.]. The test runner output is that there is "1 errors". Thank you.

  • Custom validation summary

    - by Robert Morgan
    I'm using the UpdateModel method for validation. How do I specify the text for the error messages as they appear in the validation summary? Sorry, I wasn't entirely clear. When I call UpdateModel(), if there is parsing error, for example if a string value is specified for a double field, a "SomeProperty is invalid" error message is automatically added to the ModelState. How do I specify the text for said automatically generated error message? If I implement IDataErrorInfo as suggested, it's error message property gets called for every column, regardless of whether the default binder deems it valid or not. I'd have to reimplement the parse error catching functionality that I get for free with the default binder. Incidentally, the default "SomeProperty is invalid" error messages seem to have mysteriously dissappeared in the RC. A validation summary appears and the relevant fields are highlighted but the text is missing! Any idea why this is? Thanks again and I hope all this waffle makes sense!

  • C# Lambda Problem

    - by Chris Klepeis
    Probably something simple, but as I'm new to lambda expressions, the problem evades me: m => m.contactID == contactID && m.primaryAddress == true && (m.addressTypeID == 2 || m.addressTypeID == 3) I tried to use that lambda expression but I receive an invalid operator. Is there a way to simplify this so that it would work? Edit: The equivolent sql query would be: SELECT * FROM Contact WHERE contactID = 3 AND primaryAddress = 1 AND (addressTypeID = 2 OR addressTypeID = 3) I have a repository function defined like so: public E Single(Expression<Func<E, bool>> where) { return objectSet.Single<E>(where); } I'm passing the lambda expression above into this function. Invalid operator error.

  • C# / Filter input of a textbox and display notification balloon

    - by asmo
    I'm wondering how to filter the input of a .NET textbox. I already know that I could listen for the KeyDown event and intercept the key, but that won't filter pasted strings by a right-click menu or a CTRL+V. I also don't wan't to completely disable the possibility of pasting of characters in the textbox. The paste action should be cancelled whenever it contains one or more invalid characters. Finally, I'd like to display a notification balloon whenever invalid characters are either entered or pasted. µTorrent already has this exact behavior: How can I achieve this functionality in C# ?
