  • asp.net mvc route clashing with physical path in IIS7

    - by Andrew Bullock
    I'm messing about with controller organisation and I've hit a problem. If I have the following physical structure /Home/HomeController.cs /Home/Index.aspx /Home/About.aspx and I request the URI: /Home/Index I get a 403 Directory Listing Denied :( (im using a custom IControllerFactory and IViewEngine to look in this non-default path) Why is this happening? (I know the 403 is because its hitting the /Home folder, but why is it hitting the folder?) Why doesn't the UrlRoutingModule rewrite the route and let the controller pick up the request? Application_BeginRequest fires, but then it seems to pass control back to IIS to try and serve from the filesystem. Is it the UrlRoutingModule that defaults to a physical path if it exists before rewriting? Is there a way to make this work? N.B. Please don't suggest relocating my controllers etc. I know this is an obvious option, but that isn't the question ;) Using IIS7 In Integrated Mode Thanks

  • Printer Communication Capture

    - by D-S
    If I need to post this elsewhere let me know. We have some old software thats being re-written, that uses a printerdriver to a propriatery printer. I need to rewrite the software bypassing the print driver and go directly to the printer. I do have the specs for the printer communication, thats fine, but what Id like to do is monitor the communications to the printer to view its contents (from the existing software that Im re-writing) and compare it to the specs, and what I will be sending it for validation. I have to make sure Im not missing anything. Any ideas on how I might be able to accomplish this? Thanks

  • Multiple Foriegn Keys from One Table linking to single Primary Key in second Table

    - by croker10
    Hi all, I have a database with three tables, a household table, an adults table and a users table. The Household table contains two foreign keys, iAdult1ID and iAdult2ID. The Users table has a iUserID primary key and the Adult table has a corresponding iUserID foreign key. One of the columns in the Users table is strUsername, an e-mail address. I am trying to write a query that will allow me to search for an e-mail address for either adult that has a relation to the household. So I have two questions, assuming that all the values are not null, how can I do this? And two, in reality, iAdult2ID can be null, is it still possible to write a query to do this? Thanks for your help. Let me know if you need any more information.

  • dropping user to IRB after reading from pipe

    - by aurelian
    I have this script that drops the user to an IRB session when executed. All good, but when I use *nix pipes to get the input (e.g. with cat), the IRB session ends immediately. I could reduce the script (let's call it myscript.rb) to the following: require 'irb' if $stdin.stat.size 0 @text = $stdin.read else @text= "nothing" end ARGV.clear IRB.start When executed like: ruby myscript.rb, I end up in the IRB session (as expected). But (assuming foo.txt exists in the cwd): cat foo.txt | ruby myscript.rb will just print the IRB prompt and then the IRB session is closed (I'm being dropped to $bash). Any known workarounds or ideas? BTW: it has the same behavior on ruby 1.8.7 as well as on 1.9.2.

  • How can I reuse a base class function in a derived class

    - by Armen Ablak
    Let's say we have these four classes: BinaryTree, SplayTree (which is a sub-class of BinaryTree), BinaryNode and SplayNode (which is a sub-class of BinaryNode). In class BinaryTree I have 2 Find functions, like this bool Find(const T &) const; virtual Node<T> * Find(const T &, Node<T> *) const; and in SplayTree I would like to reuse the second one, because it works in the same way (for example) as in SplayTree, the only thing different is the return type, which is SplayNode. I thought it might be enough if I use this line in SplayTree.cpp using BinaryTree::Find; but it isn't. So, how can I do this?

  • What Can A 'TreeDict' (Or Treemap) Be Used For In Practice?

    - by Seun Osewa
    I'm developing a 'TreeDict' class in Python. This is a basically a dict that allows you to retrieve its key-value pairs in sorted order, just like the Treemap collection class in Java. I've implemented some functionality based on the way unique indexes in relational databases can be used, e.g. functions to let you retrieve values corresponding to a range of keys, keys greater than, less than or equal to a particular value in sorted order, strings or tuples that have a specific prefix in sorted order, etc. Unfortunately, I can't think of any real life problem that will require a class like this. I suspect that the reason we don't have sorted dicts in Python is that in practice they aren't required often enough to be worth it, but I want to be proved wrong. Can you think of any specific applications of a 'TreeDict'? Any real life problem that would be best solved by this data structure? I just want to know for sure whether this is worth it.

  • reading and writing QByteArrays

    - by synchronicity
    I'm having trouble reading and writing QByteArray data to a file. My goal is to save QPixmap data into a QByteArray and save that QByteArray to a file (with the ability to read this QByteArray back from the file and into a QPixmap). I want to use following code from the QPixmap documentation: QPixmap pixmap(<image path>); QByteArray bytes; QBuffer buffer(&bytes); buffer.open(QIODevice::WriteOnly); pixmap.save(&buffer, "PNG"); // writes pixmap into bytes in PNG format After writing the buffer to a file, I want to be able to retrieve the QByteArray and load it back into a QPixmap using the QPixmap::loadFromData() function. Please let me know if any further clarification is needed (I'm open to alternative approaches as well, I just need to be able to read and write the QPixmap to a file! :) );

  • How do I add a new ItemTemplate to a Guidance Automation Toolkit vs2010 .vsix package?

    - by Maslow
    I have a vs2008 GAT package that has been updated to work on vs2010 which walks a developer through creating a custom solution complete with a Service layer project, Domain, usercontrol, and unit test project. I'd like to add a new ItemTemplate to the package to create a user control or dialog that adheres to our current practices. So far it seems I need a Recipe, but I can not find any reference for the GuidancePackage.xml file and how to properly add things to it, let alone how to add a new Item Template or guidance steps and decisions. How can I add an item template to my add-in?

  • How to recover from a fatal error "Allowed memory size exhausted"

    - by Matthieu
    Hi everybody, Do you know any solution to recover from the PHP fatal error : "Allowed memory size ... exhausted" I have a shutdown function that is called when a fatal error appear. This function create an ErrorException from it, and logs it. The problem is : when there is no more memory available, it can't log the error (I log in Firebug, via FirePHP, with Zend Framework). So what i mean by "how to recover from it", is how to perform basic error log, and let Zend Framework send the Headers, so that the error is logged (in Firebug in my case) as any other error ? Thanks

  • Is there a way to query if array field contains a certain value in Doctrine2?

    - by dpimka
    Starting out with Symfony2 + Doctrine. I have a table with User objects (fos_user), for which my schema contains a roles column of an 'array' type. Doctrine saves fields of this type by serializing them from php 'array' to 'longtext' (in mysql's case). So let's say I have the following users saved into DB: **User1**: array(ROLE_ADMIN, ROLE_CUSTOM1) **User2**: array(ROLE_ADMIN, ROLE_CUSTOM2) **User3**: array(ROLE_CUSTOM2) Now in my controller I want to select all users with ROLE_ADMIN set. Is there a way to write a DQL query which would directly return me User1 and User2? Or do I need to fetch all users to have Doctrine to unserialize roles column and then for each of them do in_array('ROLE_ADMIN', $user-getRoles())? I have searched the DQL part of the manual, but so far did not find anything similar to my needs...

  • How do I create the Controller for a Single Table Inheritance in Rails?

    - by Angela
    I am setting up the Single Table Inheritance, using ContactEvent as the Model that ContactEmail, ContactLetter, and ContactCall will all inherit. But I'm stumped on how to create the routing and the controller. For example, let's say I want to create a new ContactEvent with type Email. I would like a way to do the following: new_contact_event_path(contact, email) This would take the instance from Contact model and from Email model. Inside, I would imagine the contact_event_controller would need to know... @contact_event.type = (params[:email]) # get the type based on what was passed in? @contact_event.event_id = (params[:email]) #get the id for the correct class, in this case Email.id Just not sure how this works....

  • Removing items from lists and all references to them.

    - by LiamV
    I'm facing a situation where I have dependent objects and I would like to be able to remove an object and all references to it. Say I have an object structure like the code below, with a Branch type which references two Nodes. public class Node { // Has Some Data! } public class Branch { // Contains references to Nodes public Node NodeA public Node NodeB } public class Graph { public List<Node> Nodes; public List<Branch> Branches; } If I remove a Node from the Nodes list in the Graph class, it is still possible that one or more Branch objects still contains a reference to the removed Node, thus retaining it in memory, whereas really what I would quite like would be to set any references to the removed Node to null and let the garbage collection kick in. Other than enumerating through each Branch and checking each Node reference sequentially, are there any smart ideas on how I remove references to the Node in each Branch instance AND indeed any other class which reference the removed Node?

I'd like to do this without writing code for each model. What would be the best way to do this?

  • How do I use functions from a DLL?

    - by Russel
    How do I use functions from a DLL? I'm a total newbie and I don't really understand how to use functions from a DLL file. I'm trying to use MS Visual Studio 2008 (C++). My understanding is that the DLL files will have corresponding header files and as long as I include the header files and call the functions normally in my code, it should work? Is that correct? Then I would just need to have the compiled exe file be able to find the DLL? Please let me know if that is a remotely correct understanding! Thanks! Russel

  • Would this constructor be acceptable practice?

    - by Robb
    Let's assume I have a c++ class that have properly implemented a copy constructor and an overloaded = operator. By properly implemented I mean they are working and perform a deep copy: Class1::Class1(const Class1 &class1) { // Perform copy } Class1& Class1::operator=(const Class1 *class1) { // perform copy return *this; } Now lets say I have this constructor as well: Class1::Class1(Class1 *class1) { *this = *class1; } My question is would the above constructor be acceptable practice? This is code that i've inherited and maintaining.

  • What is this Design Pattern?

    - by Can't Tell
    I read the Wikipedia articles on FactoryMethod and AbstractFactory but the following code doesn't seem to fit anywhere. Can someone explain to me what the following pattern is or if it is an anti-pattern? interace PaymentGateway{ void makePayment(); } class PaypalPaymentGateway implements PaymentGateway { public void makePayment() { //some implementation } } class AuthorizeNetPaymentGateway implements PaymentGateway { public void makePayment() { //some implementation } } class PaymentGatewayFacotry{ PaymentGateway createPaymentGateway(int gatewayId) { if(gatewayId == 1) return PaypalPaymentGateway(); else if(gatewayId == 2) return AuthorizeNetPaymentGateway(); } } Let's say the user selects the payment method using a radio button on an html page and the gatewayId is derived from the radio button value. I have seen code like this and thought it was the AbstractFactory pattern but after reading the Wikipedia article, I'm having doubts.

  • Cloud HUGE data storage options?

    - by ToughPal
    Hi, Does anyone have a good suggestion on how to do video recording? We have a camera that can record and then stream live video to a server. So this means we can have 1000's of cameras sending data 24X7 for recording. We will store data for over 7 / 14 / 30 days depending on the package. Per day if a camera is sending data to the server then it will store 1.5GB. So that means there is a traffic of 1.5GB / day / camera Total monthly 45GB / month / camera (Data + bandwidth for one camera) Please let me know the most cost effective way to get this data stored? Thanks!

  • SQL to get range of results in alphabetical order

    - by Tom Gullen
    I have a table, tblTags which works in much the same way as StackOverflows tagging system. When I view a tags page, let's say the tag Tutorial I want to display the 10 tags before and after it in alphabetical order. So if we are given the tag Tutorial of ID 30 how can we return a record set in the order resembling: Tap Tart > Tutorial Umbrellas Unicorns Xylaphones I have thought of ways of doing this, badly, in my opinion as they involve retrieving ugly amounts of data. I'm not sure if it's possible to do something along the lines of (pseudo): SELECT RANGE(0 - 30) FROM tblTags ORDER BY Name ASC But how do you know the position of the tutorial tag in the list in an efficient manner without traversing the entire list until you find it? I'm using SQL Server 2008 R2 Express with LINQ if it makes any difference, SQL queries or LINQ would be great answers, thanks!

  • QT4, paginated showing elements

    - by matiit
    I am going to write an application that uses QT4 (with C++ or python it isnt important in that moment). One of functionality is "Showing all items in database". One item has a Title, author, description and photo (constant size) And there could be very many items. Let's say 400. There won't be enough space to show'em all at once time. One row will have 200px, so i need at most 4 for once time. How to paginate them? I have no idea. I can use limit and offset in SQL queries, but how to tell window: "that's 5th page"? Any solutions?

  • Model of hql query firing at back end by hql engine?

    - by Maddy.Shik
    I want to understand how hibernate execute hql query internally or in other models how hql query engine works. Please suggest some good links for same? One of reason for reading is following problem. Class Branch { //lazy loaded @joincolumn(name="company_id") Company company; } Since company is heavy object so it is lazy loaded. now i have hql query "from Branch as branch where branch.Company.id=:companyId" my concern is that if for firing above query, hql engine has to retrieve company object then its a performance hit and i would prefer to add one more property in Branch class i.e. companyId. So in this case hql query would be "from Branch as branch where branch.companyId=:companyId" If hql engine first generate sql from hql followed by firing of sql query itself, then there should be no performance issue. Please let me know if problem is not understandable.
