  • Ruby mailer is coming up with an EOFError

    - by Deadder
    I am getting an EOFError (End Of File Error) on this code in my controller. The block where the error appears is at the end of the line that says UserMailer.deliver_message( I am unaware as to how to fix this, I have been stuck for about 2 months and this site was suggested. Please help. def contact @title= "Contact Us" if request.post? @message= Message.new(params[:contact]) if @message.valid? UserMailer.deliver_message( :message => @message ) flash[:notice] = "Thank you for contacting us" redirect_to contact_url end end end Here is the message file: <%= @mail.name %> has sent feedback or a question: Message: <%= @mail.body %> From: <%= @mail.email %> And here is the UserMailer class UserMailer < ActionMailer::Base def message(mail) subject 'Feedback/Questions' recipients 'Email@email' from 'webmaster' body mail end end

  • How to create a Appointment in a Shared Calendar (Sharepoint) with VBA (Macro)?

    - by Diogo K.
    I am actually trying to make an appointment from an excel spreadsheet. I have all the information of the appointment, like subject, body, start and end dates, I actually can create an appointment but only with my personal calendar in outlook. How do I copy/move/create an appointment in a shared calendar in a sharepoint server? I've tried: Dim apOL As Object Dim objFolder As Folder Dim cro As String Set apOL = CreateObject("Outlook.Application") Set oItem = apOL.CreateItem(olApItem) Set MAPISession = apOL.Session ... cro = "stssync://sts/?ver=1.0&type=calendar&cmd=add-folder&base-url=(MY SP SERVER)&list-url=%2FLists%2FCronograma%20%20%2Fcalendar%2Easpx&guid=%7B02717CEF%2D404F%2D482F%2DA131%2D5C3C245CD268%7D&site-name=Testes&list-name=Cronograma%20-" ... Set objFolder = MAPISession.OpenSharedFolder(cro, Null,Null,Null) It gives me the error "Type Mismatch" I'd try to get the objFolder as the Sharepoint Folder then later create an local appointment and then try an Item.Move objFolder Is it the correct way?

  • Servicestack CorsFeature Global Options Handler Not Firing on Certain Routes;

    - by gizmoboy
    I've got a service setup using the CorsFeature, and am using the approach that mythz suggested in other answers, collected in a function used in the appHost file: private void ConfigureCors(Funq.Container container) { Plugins.Add(new CorsFeature(allowedOrigins: "*", allowedMethods: "GET, POST, PUT, DELETE, OPTIONS", allowedHeaders: "Content-Type, Authorization, Accept", allowCredentials: true)); PreRequestFilters.Add((httpReq, httpRes) => { //Handles Request and closes Responses after emitting global HTTP Headers if (httpReq.HttpMethod == "OPTIONS") { httpRes.EndRequest(); } }); } However, the pre-request filter is only firing on some of the service requests. One of the base entities we have in the service is a question entity, and there are custom routes defined as follows: [Route("/question")] [Route("/question/{ReviewQuestionId}", "GET,DELETE")] [Route("/question/{ReviewQuestionId}/{ReviewSectionId}", "GET")] Using POSTMAN to fire test queries (all using the OPTIONS verb), we can see that this will fire the pre-request filter: http://localhost/myservice/api/question/ But this will not: http://localhost/myservice/api/question/66 Presumably, this is because the second and third routes explicitly defined the verbs they accept, and OPTIONS isn't one of them. Is it really necessary to spell out OPTIONS in every defined route that restricts the verbs supported?

  • Zend_Form and Liskov Substitution Principle

    - by blockhead
    A very common pattern I see (I'm picking on Zend Framework, only because I was dealing with it at the moment of this question), is something like this: class My_Form extends Zend_Form { public function init() { $this->addElement(); } } Zend_Form is not an abstract class, but is perfectly usable on its own. This seems to be "recommended" as place to "encapsulate" your forms into a nice class. Does this violate the Liskov Substitution Principle? Each subclass of Zend_Form will have a wildy different behavior than the base class. Would it be better to use composition for this, or am I totally misunderstanding this principle?

  • "Personal" method in ruby

    - by steve gooberman-hill
    I'm looking for a way of making a method "personal" - note NOT PRIVATE to a class here is an example - by "personal" I mean the behaviour of method "foo" class A def foo "foo" end end class B < A def foo "bar" end end class C < B end a=A.new; b=B.new;c=C.new I'm looking for a way of producing the following behaviour a.foo #=> "foo" b.foo #=> "bar" c.foo #=> "foo" (ultimate base class method called) Any ideas?

  • How do I trigger specific parts of a storyboard in WPF?

    - by George
    I have several grids in my window. I have created a storyboard that moves them left by x pixels when a button is clicked. I want to make it so that when the button is clicked again those grids move another x pixels, however I'm unable to find out how to do this as it's not a common task on tutorials. I have tried creating a second storyboard to do this, however that won't work as then the grids will be back at their starting positions. One solution might be to create a third set of keyframes after the first two sets, and somehow pause the animation when it gets there, and resumes it again when the button is clicked, however I'm not sure how to pause a storyboard when it reaches a keyframe. This would also make reversing the grids difficult (using this approach http://social.msdn.microsoft.com/forums/en-US/wpf/thread/ac54de71-f750-4940-91a2-231810308727/), as I'd like to make another button make the grids go the other way.

  • bitshift large strings for encoding QR Codes

    - by icekreaman
    As an example, suppose a QR Code data stream contains 55 data words (each one byte in length) and 15 error correction words (again one byte). The data stream begins with a 12 bit header and ends with four 0 bits. So, 12 + 4 bits of header/footer and 15 bytes of error correction, leaves me 53 bytes to hold 53 alphanumeric characters. The 53 bytes of data and 15 bytes of ec are supplied in a string of length 68 (str68). The problem seems simple enough - concatenate 2 bytes of (right-shifted) header data with str68 and then left shift the entire 70 bytes by 4 bits. This is the first time in many years of programming that I have ever needed to do something like this, I am a c and bit shifting noob, so please be gentle... I have done a little investigation and so far have not been able to figure out how to bitshift 70 bytes of data; any help would be greatly appreciated. Larger QR codes can hold 2000 bytes of data...

  • Can I turn off implicit Python unicode conversions to find my mixed-strings bugs?

    - by Tal Weiss
    When profiling our code I was surprised to find millions of calls to C:\Python26\lib\encodings\utf_8.py:15(decode) I started debugging and found that across our code base there are many small bugs, usually comparing a string to a unicode or adding a sting and a unicode. Python graciously decodes the strings and performs the following operations in unicode. How kind. But expensive! I am fluent in unicode, having read Joel Spolsky and Dive Into Python... I try to keep our code internals in unicode only. My question - can I turn off this pythonic nice-guy behavior? At least until I find all these bugs and fix them (usually by adding a u'u')? Some of them are extremely hard to find (a variable that is sometimes a string...). Python 2.6.5 (and I can't switch to 3.x).

  • No parameterless constructor defined for this object when simply copying site

    - by jaffa
    I'm getting the above error. All I have done is copied an existing site and set-up debugging to use a different port using IISExpress in Visual Studio. Any ideas why I would suddenly get this error? Normally I get this error when StructureMap cannot for some reason resolve a dependency to inject into a controller. But this has me stumped. The code-base is the same. All I've done is copied the code into another folder!?!

  • Using a proxy for NSURLConnection

    - by SideSwipe
    Is there any way to get the content of a webfile (namely a .html Document) using a proxy, which is not defined in the system settings? I know that NSURLConnection is the right way to download a web file into a variable and not into a file (for which we should use NSURLDownload), but I don't find a way to use a proxy for it. Are there some unofficial APIs, Libraries or Classes or such I could use for what I want to do? I'm not that pro in Mac Programming, so I'm searching for something more or less simple. SideSwipe

  • Python grab class in class definition.

    - by epochwolf
    I don't even know how to explain this, so here is the code I'm trying. class Test: type = self.__name__ #self doesn't work, how do I get a reference to Test? class Test2(Test): pass #Test2.type should return "Test2" The reason I'm even trying this is I'm working on creating a base class for an orm I'm using. I want to avoid defining the table name for every model I have. Also knowing what the limits of python is will help me avoid wasting time trying impossible things.

  • How do I get all data from a mysql table via php, and print out the contents of every cell ?

    - by roberto
    Hi. I've got a database table with at least three rows in it. From php, I have successfully connected to my db and extracted all table information with 'SELECT * from mytable' . Now I want to loop through first each row, and then each cell, printing out the contents of each cell. I know this might be a simple task for a more experienced programmer, but I can't figure it out, and I can't find any examples online and it's driving me stark raving bonkers. How can I do this ?

  • alias some columns names as one field in oracle's join select query

    - by Marecky
    Hi We are developing something like a social networking website. I've got task to do 'follow me' functionality. In our website objects are users, teams, companies, channels and groups (please don't ask why there are groups and teams - it is complicated for me too, but teams are releated to user's talent) Users, teams, channels, companies and groups have all their own tables. I have a query which gets me all the follower's leaders like this select --fo.leader_id, --fo.leader_type, us.name as user_name, co.name as company_name, ch.title as channel_name, gr.name as group_name, tt.name as team_name from follow_up fo left join users us on (fo.leader_id = us.id and fo.leader_type = 'user') left join companies co on (fo.leader_id = co.user_id and fo.leader_type = 'company') left join channels ch on (fo.leader_id = ch.id and fo.leader_type = 'channel') left join groups gr on (fo.leader_id = gr.id and fo.leader_type = 'group') left join talent_teams tt on (fo.leader_id = tt.id and fo.leader_type = 'team') where follower_id = 83 I need to get all fields like: user_name, company_name, channel_name, group_name, team_name as one field in SELECT's product. I have tried to alias them all the same 'name' but Oracle numbered it. Please help :)

  • What is Ruby's double-colon (::) all about?

    - by Meltemi
    I'd probably be able to answer this for myself if "::" wasn't so hard to Google. Didn't see anything on SO so thought I'd try my luck. What is this double-colon :: all about? I see it everywhere in Rails: class User < ActiveRecord::Base or… ActionController::Routing::Routes.draw do |map| I found a definition from this guy: The :: is a unary operator that allows: constants, instance methods and class methods defined within a class or module, to be accessed from anywhere outside the class or module. but that just leads to more questions. What good is scope (private, protected) if you can just use :: to expose anything?

  • Can't access my files in ASP.NET web site

    - by jumbojs
    I'm having a very difficult time. I am running windows 2008 server, I have an Able Commerce site using ASP.NET with C#. I'm writing an automated task that will ftp some xml files down into a local directory on our web server and then the program parses the xml file and saves information to our database. The problem, once I save the files to our local directory, my program has no access to the files. The NETWORK SERVICE user permissions isn't being inherited by the xml files so my program can't do anything with them. I can manually change the permissions, but this wouldn't be automated and won't work. How can I get this to work? help please, it's very frustrating.

  • Bash variable kills script execusion

    - by Kyle Terry
    Sorry if this is better suited at serverfault, but I think it learns more towards the programming side of things. I have some code that's going into /etc/rc.local to detect what type of touch screen monitor is plugged in and changes out the xorg.conf before launching X. Here is a small snippet: CURRENT_MONITOR=`ls /dev/usb | grep 'egalax_touch\|quanta_touch'` case $CURRENT_MONITOR in '') CURRENT_MONITOR='none' ;; esac If one of those two touch screens is plugged in, it works just fine. If any other monitor is plugged in, it stops at the "CURRENT_MONITOR=ls /dev/usb | grep 'egalax_touch\|quanta_touch'." For testing I touched two files. One before creating CURRENT_MONITOR and one after CURRENT_MONITOR and only file touched before is created. I'm not a bash programmer so this might be something very obvious.

  • Making OR/M loosely coupled and abstracted away from other layers.

    - by Genuine
    Hi all. In an n-tier architecture, the best place to put an object-relational mapping (OR/M) code is in the data access layer. For example, database queries and updates can be delegated to a tool like NHibernate. Yet, I'd like to keep all references to NHibernate within the data access layer and abstract dependencies away from the layers below or above it. That way, I can swap or plug in another OR/M tool (e.g. Entity Framework) or some approach (e.g. plain vanilla stored procedure calls, mock objects) without causing compile-time errors or a major overhaul of the entire application. Testability is an added bonus. Could someone please suggest a wrapper (i.e. an interface or base class) or approach that would keep OR/M loosely coupled and contained in 1 layer? Or point me to resources that would help? Thanks.

  • Java CRTP: Works for container but not for methods?

    - by Daniel
    I have a baseclass with a protected static ArrayList. I want to have a seperate ArrayList for each kind of subclass that extends this baseclass. This is when I applied CRTP: public class BaseExample<T> { protected static ArrayList<Integer> data = new ArrayList<Integer>(); } This works just fine. However, when I try to implement the following static method in the same base class, it doesn't adhere to CRTP: public static void clear() { data.clear(); } For example: class SubExample extends BaseExample<SubExample> { // insertion methods accessing 'data' field // these work fine :) } SubExample.clear(); // does not seem to clear data container Do I need to somehow explicitly specify T in my baseclass clear method? Note: These are all pure static classes.

  • Grab triangles within a lower triangle

    - by Tyler Rinker
    I have the need to grab all the thee element triangles that make up the lower triangle of a symmetric matrix. I can not think of how to grab all these pieces in the order of far left column working down and then next column to the right and so on. I know that the numbe rof mini triangles inside of the lower triangle is: n = x(x - 1)/2 where: x = nrow(mats[[i]]) Here I've created three matrices with letters (it's easier for me to conceptualize this way) and the elements in the order I'm looking for: FUN <- function(n) { matrix(LETTERS[1:(n*n)], n) } mats <- lapply(3:5, FUN) So this is the output I'd like to get (I put it in code rather than output format) for each of the matrices created above: list(c("B", "C", "F")) list(c("B", "C", "G"), c("C", "D", "H"), c("G", "H", "L")) list(c("B", "C", "H"), c("C", "D", "I"), c("D", "E", "J"), c("H", "I", "N"), c("I", "J", "O"), c("N", "O", "T")) How can I do this task in the fastest manner possible while staying in base R? Not sure if this visual of what I'm after is helpful but it may be:

  • Javascript clarity of purpose

    - by JesDaw
    Javascript usage has gotten remarkably more sophisticated and powerful in the past five years. One aspect of this sort of functional programming I struggle with, esp with Javascript’s peculiarities, is how to make clear either through comments or code just what is happening. Often this sort of code takes a while to decipher, even if you understand the prototypal, first-class functional Javascript way. Any thoughts or techniques for making perfectly clear what your code does and how in Javascript? I've asked this question elsewhere, but haven't gotten much response.

  • Python IDLE freezes

    - by ooboo
    This is absolutely frustrating, but I am not sure if the following is an issue only on my machine or with IDLE in general. When attempting to print a long list in the shell, and that could happen by accident while debugging, the program crushes and you have to restart it manually. Even worse, if you have a few editor windows open, it always spawns a few sub-processes, and each of these has to be manually shut down from the task manager. Is there any way to avoid that? I am using Python 3, by the way.

  • Build Google App Engine Java source from Eclipse

    - by Robottinosino
    I would like to try to build Google App Engine for Java from source. I have tried this: I don't know how to solve the javac Ant task. I am on Mac OS X 10.6.8. The reason why I am trying to to create a Java Project from the source is that when I try to debug/step-into the sources downloaded from SVN, something is wrong in Eclipse and it does not track execution at the right code line. It seems to be executing "comment lines"? So I don't get an accurate tracking of the code path. I think what I would ideally need is: 1) svn checkout command with matching REV number of latest SDK 2) wget command downloading matching jar

  • help in security assignment

    - by scatman
    i have to write a program that sniffs network packets (part1-the simple part). and i have to update the program (part2) so that it will be able to terminate connections. the specific requirements are: construct raw packets by specifying data link layer and network layer information including appropriate source and destination MAC and IP addresses. These packets are intended to terminate the connection. To do so, you should used SOCK_RAW as the socket type to be able to set the header information by yourself. can anybody give me some ideas on the second part? should i hijack the session,apply a dos attack on one of the users?? all i need is some tips of how to terminate the connection. i am using c programming language. and this is a course assignment for the security course.
