  • Using authsmtp from a Grails server

    - by Simon
    This is quite a specific question, and I have had no luck on the grails nabble forum, so I thought I would post here. I am using the grails mail plug-in, but I think my question is a general one about using authsmtp as an email gateway from my server. I am having trouble sending mail from my app using authsmtp. I have installed and configured the mail plugin and was originally using my ISP's SMTP server to send mails. However when I deployed to AWS EC2 this failed because my elastic IP was blocked by the SMTP host. So I bought myself an authsmtp account and set up my server email address as an accepted one at authsmtp. I then changed my configuration in SecurityConfig.groovy to point to the authsmtp server that I had been designated... mailHost = "mail.authsmtp.com" mailUsername = "myusername" mailPassword = "mypassword" mailProtocol = "smtp" mailFrom = "[email protected]" mailPort = 2525 ...and I'm just trying to get this to work locally before I deploy back up to AWS. Sending mail fails and in my log I have this exception: 2010-02-13 10:59:44,218 [http-8080-1] ERROR service.EmailerService - Failed to send emails: Failed messages: com.sun.mail.smtp.SMTPSendFailedException: 513 5.0.0 Your email system must authenticate before sending mail. org.springframework.mail.MailSendException; nested exception details (1) are: Failed message 1: com.sun.mail.smtp.SMTPSendFailedException: 513 5.0.0 Your email system must authenticate before sending mail. at com.sun.mail.smtp.SMTPTransport.issueSendCommand(SMTPTransport.java:1388) at com.sun.mail.smtp.SMTPTransport.mailFrom(SMTPTransport.java:959) at com.sun.mail.smtp.SMTPTransport.sendMessage(SMTPTransport.java:583) I'm a bit lost since the username and password I provide in the configuration are definitely correct. A terse and not very helpful conversation with authsmtp support suggests that I need to MD5 and/or base64 encode my credentials before sending, so my question is in three parts... 1) any idea what's going on with the failure and why that message is appearing? 2) how would I encode the credentials to pass to authsmtp and how would I configure that for the mail plugin 3) has anyone successfully connected and sent mail through authsmtp from the mail plugin and specifically from AWS EC2?

  • .NET Hashtable - "Same" key, different hashes

    - by Simon Lindgren
    Is it possible for two .net strings to have different hashes? I have a Hashtable with amongst others the key "path". When I loop through the elements in the table to print it, i can see that the key exists. When trying to looking it up however, there is no matching element. Debugging suggests that the string I'm looking for has a different hash than the one I'm supplying as the key. This code is in a Castle Monorail project, using brail as a view engine. The key I'm looking for is inserted by a brail line like this: UrlHelper.Link(node.CurrentPage.LinkText, {@params: {@path: "/Page1"}}) Then, in this method (in a custom IRoutingRule): public string CreateUrl(System.Collections.IDictionary parameters) { PrintDictionaryToLog(parameters); string url; if (parameters.Contains("path")) { url = (string)parameters["path"]; } else { return null; } } The key is printed to the log, but the function returns null. I didn't know this could even be a problem with .net strings, but I guess this is some kind of encoding issue? Oh, and this is running mono.

  • IIS7 Modules - managed or native?

    - by Simon Linder
    Hi all, as the old ISAPI filters are going to die sooner or later, I want to rewrite an old ISAPI filter that was used in IIS 6 into a module for use in IIS 7. The module will be used globally, meaning it will be used within each site, on a Windows Server 2008 R2 with IIS 7.5 installed, that will host several thousand web sites and managing about 50 application pools. My question now is if I should write that module in managed or unmanaged code? One of my concerns regarding managed code is the massive memory consumption due to the .NET framework overhead. I don't know how this would effect the server's performance. I already wrote modules in managed as well as in unmanaged code. So this is not the bothering my decision. But I would prefer to write the module in C# if there are no huge drawbacks. Any suggestions about that issue?

  • Unit test complex classes with many private methods

    - by Simon G
    Hi, I've got a class with one public method and many private methods which are run depending on what parameter are passed to the public method so my code looks something like: public class SomeComplexClass { IRepository _repository; public SomeComplexClass() this(new Repository()) { } public SomeComplexClass(IRepository repository) { _repository = repository; } public List<int> SomeComplexCalcualation(int option) { var list = new List<int>(); if (option == 1) list = CalculateOptionOne(); else if (option == 2) list = CalculateOptionTwo(); else if (option == 3) list = CalculateOptionThree(); else if (option == 4) list = CalculateOptionFour(); else if (option == 5) list = CalculateOptionFive(); return list; } private List<int> CalculateOptionOne() { // Some calculation } private List<int> CalculateOptionTwo() { // Some calculation } private List<int> CalculateOptionThree() { // Some calculation } private List<int> CalculateOptionFour() { // Some calculation } private List<int> CalculateOptionFive() { // Some calculation } } I've thought of a few ways to test this class but all of them seem overly complex or expose the methods more than I would like. The options so far are: Set all the private methods to internal and use [assembly: InternalsVisibleTo()] Separate out all the private methods into a separate class and create an interface. Make all the methods virtual and in my tests create a new class that inherits from this class and override the methods. Are there any other options for testing the above class that would be better that what I've listed? If you would pick one of the ones I've listed can you explain why? Thanks

  • Mapping two tables 0..n in Hibernate

    - by simon
    I have a table Users CREATE TABLE "USERS" ( "ID" NUMBER NOT NULL , "LOGINNAME" VARCHAR2 (150) NOT NULL ) and I have a second table SpecialUsers. No UserId can occur twice in the SpecialUsers table, and only a small subset of the ids of users in the Users table are contained in the SpecialUsers table. CREATE TABLE "SPECIALUSERS" ( "USERID" NUMBER NOT NULL, CONSTRAINT "PK_SPECIALUSERS" PRIMARY KEY ("USERID") ) ALTER TABLE "SPECIALUSERS" ADD CONSTRAINT "FK_SPECIALUSERS_USERID" FOREIGN KEY ("USERID") REFERENCES "USERS" ("ID") / Mapping the Users table in Hibernate works ok <hibernate-mapping package="com.initech.domain"> <class name="com.initech.User" table="USERS"> <id name="id" column="ID" type="java.lang.Long"> <meta attribute="use-in-tostring">true</meta> <generator class="sequence"> <param name="sequence">SEQ_USERS_ID</param> </generator> </id> <property name="loginName" column="LOGINNAME" type="java.lang.String" not-null="true"> <meta attribute="use-in-tostring">true</meta> </property> </class> </hibernate-mapping> But I'm struggling in creating the mapping for the SpecialUsers table. All the examples (e.g. in Hibernate documentation) in Internet I found don't have this type of self-reference. I tried a mapping like this: <hibernate-mapping package="com.initech.domain"> <class name="com.initech.User" table="SPECIALUSERS"> <id name="id" column="USERID"> <meta attribute="use-in-tostring">true</meta> <generator class="foreign"> <param name="property">user</param> </generator> </id> <one-to-one name="user" class="User"/> </class> </hibernate-mapping> but got the error Invocation of init method failed; nested exception is org.hibernate.DuplicateMappingException: Duplicate class/entity mapping com.initech.User How should I map the SpecialUsers table? What I need on the application level is a list of the User objects contained in the SpecialUsers table.

  • Get all window handles for a process

    - by Jeremy
    Using Microsoft Spy++, I can see that the following windows that belong to a process: Process XYZ window handles, displayed in tree form just like Spy++ gives me: A B C D E F G H I J K I can get the process, and the MainWindowHandle property points to the handle for window F. If I enumerate the child windows using I can get a list of window handles for G through K, but I can't figure out how to find the window handles for A through D. How can I enumerate windows that are not children of the handle specified by MainWindowHandle of the Process object? To enumerate I'm using the win32 call: [System.Runtime.InteropServices.DllImport(strUSER32DLL)] public static extern int EnumChildWindows(IntPtr hWnd, WindowCallBack pEnumWindowCallback, int iLParam);

  • mEncrypt/Decrypt binary mp3 with mcrypt, missing mimetype

    - by Jeremy Dicaire
    I have a script that read a mp3 file and encrypt it, I want to be able to decrypt this file and convert it to base64 so it can play in html5. Key 1 will be stored on the page and static, key2 will be unique for each file, for testing I used: $key1 = md5(time()); $key2 = md5($key1.time()); Here is my encode php code : //Get file content $file = file_get_contents('test.mp3'); //Encrypt file $Encrypt = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key1, $file, MCRYPT_MODE_CBC, $key2); $Encrypt = trim(base64_encode($Encrypt)); //Create new file $fileE = "test.mp3e"; $fileE = fopen($file64, 'w') or die("can't open file"); //Put crypted content fwrite($fileE, $Encrypt); //Close file fclose($fileE); Here is the code that doesnt work (decoded file is same size, but no mimetype): //Get file content $fileE = file_get_contents('test.mp3e'); //Decode $fileDecoded = base64_decode($fileE); //Decrypt file $Decrypt = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key1, $fileDecoded, MCRYPT_MODE_CBC, $key2); $Decrypt = trim($Decrypt); //Create new file $file = "test.mp3"; $file = fopen($file, 'w') or die("can't open file"); //Put crypted content fwrite($file, $Decrypt); //Close file fclose($file);

  • Does code in the constructor add to code in subclass constructors?

    - by Jeremy Rudd
    Does code in the constructor add to code in subclass constructors? Or does the subclass's constructor override the superclass? Given this example superclass constructor: class Car{ function Car(){ trace("CAR") } } ...and this subclass constructor: class FordCar extends Car{ function FordCar(){ trace("FORD") } } When an instance of FordCar is created, will this trace "Car" and "Ford" ??

  • Using Linq to group a list of objects into a new grouped list of list of objects

    - by Simon G
    Hi, I don't know if this is possible in Linq but here goes... I have an object: public class User { public int UserID { get; set; } public string UserName { get; set; } public int GroupID { get; set; } } I return a list that may look like the following: List<User> userList = new List<User>(); userList.Add( new User { UserID = 1, UserName = "UserOne", GroupID = 1 } ); userList.Add( new User { UserID = 2, UserName = "UserTwo", GroupID = 1 } ); userList.Add( new User { UserID = 3, UserName = "UserThree", GroupID = 2 } ); userList.Add( new User { UserID = 4, UserName = "UserFour", GroupID = 1 } ); userList.Add( new User { UserID = 5, UserName = "UserFive", GroupID = 3 } ); userList.Add( new User { UserID = 6, UserName = "UserSix", GroupID = 3 } ); I want to be able to run a Linq query on the above list that groups all the users by GroupID. So the out pub will be a list of user lists that contains user (if that makes sense?). So the out put would be something like: GroupedUserList UserList UserID = 1, UserName = "UserOne", GroupID = 1 UserID = 2, UserName = "UserTwo", GroupID = 1 UserID = 4, UserName = "UserFour", GroupID = 1 UserList UserID = 3, UserName = "UserThree", GroupID = 2 UserList UserID = 5, UserName = "UserFive", GroupID = 3 UserID = 6, UserName = "UserSix", GroupID = 3 I've tried using the groupby linq clause but this seems to return a list of keys and its not grouped by correctly: var groupedCustomerList = userList.GroupBy( u => u.GroupID ).ToList(); Any help would be much appreciated. Thanks

  • Can't Reorder a UITableViewCell into _some_ empty sections of a UITableView

    - by Jeremy Lightsmith
    If I have a UITableView in edit mode, w/ reordering turned on, it seems I can't move some (but not all) cells into some (but not all) empty sections. For example, if I have this layout : Section 1 apple banana Section 2 doberman Section 3 Section 4 Then I can move 'doberman' into any slot in section 1 (except after 'banana'), but I can't move it into section 3 or 4 at all. On the other hand, I can move 'apple' & 'banana' into section section 2 (except after 'doberman'), and I CAN move it into section 3, but NOT into section 4. What gives? this seems like buggy behavior. How do people work around it? Is apple aware of this bug?

Any ideas if I can strip/replace these using PHP when they get displayed out of my mySQL table. Here is the link to the page that spits out the dodgy characters, you can see the 'black diamonds of doom' which are causing the headaches. http://linq.milkbarstudios.com/news_detail.php?id=3 Any suggestions would be greatly accepted!

  • NHibernate Projections to retrieve a Collection?

    - by Simon Söderman
    I´m having some trouble retrieving a collection of strings in a projection: say that I have the following classes public class WorkSet { public Guid Id { get; set; } public string Title { get; set; } public ISet<string> PartTitles { get; protected set; } } public class Work { public Guid Id { get; set; } public WorkSet WorkSet { get; set; } //a bunch of other properties } I then have a list of Work ids I want to retrieve WorkSet.Title, WorkSet.PartTitles and Id for. My tought was to do something like this: var works = Session.CreateCriteria<Work>() .Add(Restrictions.In("Id", hitIds)) .CreateAlias("WorkSet", "WorkSet") .SetProjection( Projections.ProjectionList() .Add(Projections.Id()) .Add(Projections.Property("WorkSet.Title")) .Add(Projections.Property("WorkSet.PartTitles"))) .List(); The Id and Title loads up just fine, but the PartTitles returns null. Suggestions please!

  • Objectdatasource and Gridview : Sorting, paging, filtering

    - by Simon
    Hi there, Im using entity framework 1.0 and trying to feed out a Gridview with a objectdatasource that have access to my facade. The problem is, that it seems to be particulary difficult and haven't seen anything that realy do what i want it to do on the internet. For those who know, a gridview feeded with an objectdatasource, it can't sort automaticaly then you must do it manually. It's not that bad. Where it becomes a nightmare, its when we add paging and filter settings to a gridview's datasource. After many hours searching on the internet, i'm asking you, guys, if anyone knows a link that can explain me how to mix Pagging, Sorting and filtering for a gridview and an objectdatasource! Thanks in advance and sorry for my english.

  • How to formulate a SQL Server indexed view that aggregates distinct values?

    - by Jeremy Lew
    I have a schema that includes tables like the following (pseudo schema): TABLE ItemCollection { ItemCollectionId ...etc... } TABLE Item { ItemId, ItemCollectionId, ContributorId } I need to aggregate the number of distinct contributors per ItemCollectionId. This is possible with a query like: SELECT ItemCollectionId, COUNT(DISTINCT ContributorId) FROM Item GROUP BY ItemCollectionId I further want to pre-calculate this aggregation using an indexed (materialized) view. The DISTINCT prevents an index being placed on this view. Is there any way to reformulate this which will not violate SQL Server's indexed view constraints?

  • Why does SFINAE not apply to this?

    - by Simon Buchan
    I'm writing some simple point code while trying out Visual Studio 10 (Beta 2), and I've hit this code where I would expect SFINAE to kick in, but it seems not to: template<typename T> struct point { T x, y; point(T x, T y) : x(x), y(y) {} }; template<typename T, typename U> struct op_div { typedef decltype(T() / U()) type; }; template<typename T, typename U> point<typename op_div<T, U>::type> operator/(point<T> const& l, point<U> const& r) { return point<typename op_div<T, U>::type>(l.x / r.x, l.y / r.y); } template<typename T, typename U> point<typename op_div<T, U>::type> operator/(point<T> const& l, U const& r) { return point<typename op_div<T, U>::type>(l.x / r, l.y / r); } int main() { point<int>(0, 1) / point<float>(2, 3); } This gives error C2512: 'point<T>::point' : no appropriate default constructor available Given that it is a beta, I did a quick sanity check with the online comeau compiler, and it agrees with an identical error, so it seems this behavior is correct, but I can't see why. In this case some workarounds are to simply inline the decltype(T() / U()), to give the point class a default constructor, or to use decltype on the full result expression, but I got this error while trying to simplify an error I was getting with a version of op_div that did not require a default constructor*, so I would rather fix my understanding of C++ rather than to just do what works. Thanks! *: the original: template<typename T, typename U> struct op_div { static T t(); static U u(); typedef decltype(t() / u()) type; }; Which gives error C2784: 'point<op_div<T,U>::type> operator /(const point<T> &,const U &)' : could not deduce template argument for 'const point<T> &' from 'int', and also for the point<T> / point<U> overload.

  • Zend_Validate_Abstract custom validator not displaying correct error messages.

    - by Jeremy Dowell
    I have two text fields in a form that I need to make sure neither have empty values nor contain the same string. The custom validator that I wrote extends Zend_Validate_Abstract and works correctly in that it passes back the correct error messages. In this case either: isEmpty or isMatch. However, the documentation says to use addErrorMessages to define the correct error messages to be displayed. in this case, i have attached ->addErrorMessages(array("isEmpty"=>"foo", "isMatch"=>"bar")); to the form field. According to everything I've read, if I return "isEmpty" from isValid(), my error message should read "foo" and if i return "isMatch" then it should read "bar". This is not the case I'm running into though. If I return false from is valid, no matter what i set $this-_error() to be, my error message displays "foo", or whatever I have at index[0] of the error messages array. If I don't define errorMessages, then I just get the error code I passed back for the display and I get the proper one, depending on what I passed back. How do I catch the error code and display the correct error message in my form? The fix I have implemented, until I figure it out properly, is to pass back the full message as the errorcode from the custom validator. This will work in this instance, but the error message is specific to this page and doesn't really allow for re-use of code. Things I have already tried: I have already tried validator chaining so that my custom validator only checks for matches: ->setRequired("true") ->addValidator("NotEmpty") ->addErrorMessage("URL May Not Be Empty") ->addValidator([*customValidator]*) ->addErrorMessage("X and Y urls may not be the same") But again, if either throws an error, the last error message to be set displays, regardless of what the error truly is. I'm not entirely sure where to go from here. Any suggestions?

  • Is there a dictionary about common programming vocabulary?

    - by _simon_
    When I need a name for a new class that extends behaviour of an existing class, I usually have hard time to come up with a name for it. For example, if I have a class MyClass, then the new class could be named something like MyClassAdapter, MyClassCalculator, MyClassDispatcher, MyClassParser,... This new name should of course represent the behaviour of the class and would ideally be same as the design pattern in which it is used (Adapter, Decorator, Factory,...). But since we don't overuse design patterns, this is not always the solution :) So, do you know for a dictionary or a list of common words, that we can use to represent the behaviour of the class, containing a short description of the expected behaviour? Some examples: replicator, shadow, token, acceptor, worker, mapper, driver, bucket, socket, validator, wrapper, parser, verifier,... You could also look at this list as a cheat sheet for metaphors, with which you can better understand your problem domain.

  • How can I tell if AUCTeX is available?

  • Sharing view logic in Django

    - by Jeremy B.
    I've begun diving into Django again and I'm having trouble finding the parallel to some common concepts from my life in C#. While using .NET MVC I very often find myself creating a base controller which will provide a base action implementation to take care of the type of stuff I want to do on every request, like retrieving user information, getting localization values. Where I'm finding myself confused is how to do this in Django. I am getting more familiar with the MVT concept but I can't seem to find how to solve this scenario. I've looked at class based views and the generic views yet they didn't seem to work how I expected. What am I missing? How can i create default logic that each view will be instructed to run but not have to write it in each view method?

  • Checked status not updated in CheckBox template

    - by Simon
    Hey there. I'm trying to create an hyperlink that changes its text depending on a boolean value. I thought I could leverage the IsChecked method of a CheckBox. So I wrote this ControlTemplate for a CheckBox: <CheckBox Checked="CheckBox_Checked" IsChecked="{Binding Path=SomeBool, Mode=TwoWay}"> <CheckBox.Template> <ControlTemplate TargetType="{x:Type CheckBox}"> <BulletDecorator> <BulletDecorator.Bullet> <TextBlock> <Hyperlink> <TextBlock x:Name="TextBoxHyperlink">Unchecked</TextBlock> </Hyperlink> </TextBlock> </BulletDecorator.Bullet> <ContentPresenter /> </BulletDecorator> <ControlTemplate.Triggers> <Trigger Property="IsChecked" Value="True"> <Setter TargetName="TextBoxHyperlink" Property="Text" Value="Checked" /> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </CheckBox.Template> </CheckBox> But when I click on the hyperlink, nothing happens. The checked status is not changed and the Text property of the TextBlock is not updated. Any ideas?

  • How can I create a new email account in Java?

    - by Jeremy Goodell
    I am able to send and receive emails from my JSPs and associated Java code using the Java Mail API (javax.mail.*). Now I would like to create a new POP3 email account programmatically when a user registers for my site. I've found surprisingly little information about this with web searches. I would think it would be a somewhat common problem. It appears that the Java Mail API does not provide any assistance in this area. I have many email accounts available under my godaddy account, and to manually create an account, I just go to the godaddy email control panel, click Add, and specify the email address and password. This is exactly what I would like to do via a Java program. Any ideas?

  • Issue with translating a delegate function from c# to vb.net for use with Google OAuth 2
