  • WCF Custom WSDL XmlSerializerOperationBehavior

    - by Jeff
    Hi, I have code that builds a custom WCF wsdl on the fly. In one particular scenario, the WSDL exported should use the XmlSerializerOperationBehavior as the IWsdlExportExtension as opposed to the default DataContractSerializerOperationBehavior IWsdlExportExtension. However, every time I try this from the WSDL generation code, I get a null reference exception from the ExportBody method of the XmlSerializerMessageContractExporter (which is used internally in System.ServiceModel by the XmlSerializerOperationBehavior ExportContract method). I've reflector'd it and I can't see anything obviously wrong. For some reason, .NET also doesn't want to work with source stepping in this scenario... Simply, the most basic way I can reproduce this is var c = ContractDescription.GetContract(typeof(IMyService)); foreach (var op in c.Operations) { op.Behaviors.Remove(typeof(DataContractSerializerOperationBehavior)); op.Behaviors.Insert(0, new XmlSerializerOperationBehavior(op)); } new WsdlExporter().ExportContract(c); // throws NullReferenceException Does anyone have any ideas on this? Thanks very much.

  • ActionMailer execution timeout

    - by user275729
    When trying to send an email to the user for reseting their password, I keep getting an execution timed out error. Other mailer functions work, so I know that the config settings are correct. The header reads: "Timeout::Error in Password resetsController#create" Here is the password_resets_controller: def create @user = User.find_by_email(params[:email]) if @user User.deliver_password_reset_instructions(@user.id) flash[:notice] = "Instructions to reset your password have been emailed to you. " + "Please check your email." redirect_to '/' else flash[:notice] = "No user was found with that email address" render :action => :new end end Here is the method inside of User.rb def self.deliver_password_reset_instructions(user_id) user = User.find(user_id) user.reset_perishable_token! Emailer.deliver_password_reset_instructions(user) end Finally, here is the actual method inside of emailer.rb: default_url_options[:host] = "http://0.0.0.0:3000" #development def password_reset_instructions(user) @subject = "FanGamb Password Reset" @from = '[email protected]' @recipients = user.email @sent_on = Time.now @body["edit_password_reset_url"] = edit_password_reset_url(user.perishable_token) @headers["X-SMTPAPI"] = "{\"category\" : \"Password Recovery\"}"#send grid category header end Why is "Password" in the error message referred to causing a timeout::error

  • Can i upload my apk to SD Card instead of internal storage?

    - by Ahmed Al Khashab
    My APK is big, 70 MB. I don't have any problems when I install it in external storage, but when I upload it to phone before installing, the APK goes to internal storage and my testing phone doesn't have enough space in internal storage and a lot of android phones don't have enough internal space for 70 MB... Can I upload my APK straight to the SD Card instead of internal storage first? upload mean "upload from my eclipse while runnig , or download from market, apk will go to internal storage but i want apk go to external and start install from external"

  • Add api key to every request in ActiveResource

    - by Jared
    I have 2 RESTful Rails apps I'm trying to make talk to each other. Both are written in Rails 3 (beta3 at the moment). The requests to the service will require the use an api key which is just a param that needs to be on every request. I can't seem to find any information on how to do this. You define the url the resource connects to via the site= method. There should be an equivalent query_params= method or similar. There is one good blog post I found related to this and it's from October 2008, so not exactly useful for Rails 3.

  • Why do socket.makefile objects fail after the first read for UDP sockets?

    - by Eli Courtwright
    I'm using the socket.makefile method to create a file-like object on a UDP socket for the purposes of reading. When I receive a UDP packet, I can read the entire contents of the packet all at once by using the read method, but if I try to split it up into multiple reads, my program hangs. Here's a program which demonstrates this problem: import socket from sys import argv SERVER_ADDR = ("localhost", 12345) sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) sock.bind(SERVER_ADDR) f = sock.makefile("rb") sock.sendto("HelloWorld", SERVER_ADDR) if "--all" in argv: print f.read(10) else: print f.read(5) print f.read(5) If I run the above program with the --all option, then it works perfectly and prints HelloWorld. If I run it without that option, it prints Hello and then hangs on the second read. I do not have this problem with socket.makefile objects when using TCP sockets. Why is this happening and what can I do to stop it?

  • Facebook calling Google App Engine code using GET instead of POST

    - by Nick Gotch
    I've been developing a Facebook app using Google App Engine in Python and the pyfacebook bindings. For weeks everything worked fine but suddenly it stopped. At first I thought it was a code change so I rolled back the entire dev directory to a version I knew worked, but still it failed. It's possible a change I made to the application's settings caused the issue but, if so, I can't figure out what. I've figured out that the problem is that instead of calling the post(self) method of my Main class, Facebook is calling using a GET. Does anyone know why Facebook would use a GET method instead of a POST? It's an IFrame app. Thanks,

  • C# int to byte[]

    - by Petoj
    If I need to convert an int to byte[] I could use Bitconvert.GetBytes(). But if I should follow this: An XDR signed integer is a 32-bit datum that encodes an integer in the range [-2147483648,2147483647]. The integer is represented in two's complement notation. The most and least significant bytes are 0 and 3, respectively. Integers are declared as follows: Taken from RFC1014 3.2. What method should I use then if there is no method to do this? How would it look like if you write your own? I don't understand the text 100% so I can't implement it on my own.

  • XPath find element based on ancestor element

    - by martymcfly
    Hi, again I have Java AST which is created from public class Test { String o = new String("hh"); public void wrong1() { synchronized(o) { // huhu } } } I try to create a XPath query which finds the synchronized block in which the defined String variable o is used. As the definition is above it is an ancestor of the SynchronizedStatement, but I dont get it working //SynchronizedStatement[Expression/PrimaryExpression/PrimaryPrefix/Name[@Image=ancestor::ClassOrInterfaceBody[ClassOrInterfaceBodyDeclaration/FieldVariableDeclaratorId/@Image]]] I know that /SynchronizedStatement[Expression/PrimaryExpression/PrimaryPrefix/Name[@Image= is correct, my problem is how to address the ancestor ClassOrInterfaceBody part. Hope its clear what i mean ;-) Thanks

  • By-Name-Parameters for Constructors

    - by hotzen
    Hello, coming from my other question is there a way to get by-name-parameters for constructors working? I need a way to provide a code-block which is executed on-demand/lazy/by-name inside an object and this code-block must be able to access the class-methods as if the code-block were part of the class. Following Testcase fails: package test class ByNameCons(code: => Unit) { def exec() = { println("pre-code") code println("post-code") } def meth() = println("method") def exec2(code2: => Unit) = { println("pre-code") code2 println("post-code") } } object ByNameCons { def main(args: Array[String]): Unit = { val tst = new ByNameCons { println("foo") meth() // knows meth() as code is part of ByNameCons } tst.exec() // ByName fails (executed right as constructor) println("--------") tst.exec2 { // ByName works println("foo") //meth() // does not know meth() as code is NOT part of ByNameCons } } } Output: foo method pre-code post-code -------- pre-code foo post-code

  • Change Laptop Wireless Card?

    - by Craig
    I have just bought a new Samsung RV511 Laptop (the i5 Version). Anyway it comes installed with a Broadcom Wifi Card, I have a Super Atheros Mini Wifi Card that I would like to swap for the Broadcom one. I use Atheros for security auditing purposes in Linux that the Broadcom one is not good for. Trouble is I have never got to the barebones of a laptop, although I am a Custom PC Builder, laptops i generally have no concern for. Take a look at this picture, I took one back panel off to reveal some of the components: I believe the Wireless Card is where I marked the arrow pointing too. That little white square thing appears to be a sticker of the Wifi card, it says WLAN. How can I access it to swap it with my Atheros one. Do I need to remove all the outermost screws? There are screws located to the right of where I scribbled in Yellow and next to the HDD, do I just remove those? I dont want to destroy the machine, only just got it today. Appreciate some help thanks.

  • Finding the second highest number in array

    - by Richard Jackson
    I'm having difficulty to understand the logic behind the method to find the second highest number in array. The method used is to find the highest in the array but less than the previous highest (which has already been found). The thing that I still can't figure it out is why || highest_score == second_highest is necessary. For example I input three numbers: 98, 56, 3. Without it, both highest and second highest would be 98. Please explain. int second highest = score[0]; if (score[i] > second_highest && score[i] < highest_score || highest_score == second_highest) second_highest = score[i];

  • ASP.NET MVC AJAX value not displaying

It is printing undefined there. Is there a problem in javascript method OnSuccess?

  • Why not use PHP's built-in session handling?

    - by Dougal
    Is there currently - or has there ever been - any serious or significant problem with PHP's built-in session handling? I mean, it's always worked for me and my projects. But I see some codebases and frameworks out there seem to use a custom handler. Is this reinventing the wheel? Or improving on some flaws? What flaws?

  • Are there macro facility for Java or C#?

    - by h2g2java
    Macros are useful. Therefore, I occasionally bemoan the absence of macros in Java and C#. Macros allow me to force in-line but allow me the code-manageability of non-macro code. Is there any Java- or C#-based project/product somewhere out there that effectively allow macros or specifying in-line expansion. I am thinking of something like @macro public void hello(int x){ ... } or when I call a method, an @inline annotation preceding the call would effect the called-method to be in-lined. or, should I need to know that I should just trust the compiler to make the best the decision for me that at the best of its analysis it might in-line a call. I hope this question will not lead to debating the pro/cons/usefulness of macros.
