• AutoScroll issues with custom layout on Windows Forms application

  - by Lurker Indeed

  I've implemented a basic custom layout engine in Windows Forms that does control sizing and positioning. I was hoping to allow the AutoScroll features to work untouched, but any time I have enough controls on the screen to require a scroll bar, some of the layout events that get fired (i.e, a rich text box that expands the height as it types) not only fire the layout events, but they force the scroll bar back at (0,0). Do I have any options besides looking at the scroll position and positioning the controls manually based on that?

• Arranging models, views, controllers in a Kohana 3 project

  - by Pekka

  I'm looking at how to set up a mid-sized web application with Kohana 3. I have implemented MVC patterns in the past but never worked against a "formalized" MVC framework so I'm still getting my head around the terminology - toying around with basic examples, building views and templates, and so on. I'm progressing fairly well but I want to set up a real-world web project (one of my own that I've been planning for quite some time now) as a learning object. I learn best by example, but example-based documentation is a bit sparse for Kohana 3 right now - they say so themselves on the site. While I'm not worried about getting into the framework soon enough, I'm a bit concerned about arranging a healthily structured code base from the start - i.e. how to split up controllers, how to name them, and how to separate the functionality into the appropriate models. My application could, in its core, be described as a business directory with a main businesses table. Businesses can be listed by category and by street name. Each business has a detail page. Business owners can log in and edit their business's entry. Businesses can post offers into an offers table. I know this is pretty vague, but I don't want to cram too much information into this question. I'll be more than happy to go into more detail if needed. Supposing I have all the basic functionality worked out and in place already - list all businesses, edit business, list businesses by street name, create offer, and so on, and I'm just looking for how to fit the functionality into a MVC pattern and into a Kohana application structure that can be easily extended: Do you know real-life, publicly accessible examples of "database-heavy" applications like directories, online communities... with a log-in area built on Kohana 3 where I could take a peek how they do it? Are there conventions or best practices on how to structure an extendable login area for end users in a Kohana project that is not only able to handle a business directory page, but further products on separate pages as well? Do you know application structuring HOWTOs or best practices for Kohana 3 not mentioned in the user guide and the inofficial Wiki? Have you built something similar and could give me some recommendations?

• SQLCMD Restore works in Management Studio but not from DOS prompt

  - by Gautam

  Any idea why my Restore command works fine when run in Management Studio 2008 but not when run from the dos prompt? Shown below is the error when running from the dos prompt.

Previous messages provide details. Msg 3013, Level 16, State 1, Server GAUTAM, Line 1 RESTORE DATABASE is terminating abnormally. However if I execute this directly in Management Studio 2008, it works fine: RESTORE DATABASE [Sample.Db] FROM DISK = N'C:\Sample.Db.bak' WITH FILE = 1, MOVE N'Sample.Db' TO N'C:\Program Files\Microsoft SQL Server\MSSQL10.SQL2008\MSSQL\DATA\Sample.Db.mdf', MOVE N'Sample.Db_log' TO N'C:\Program Files\Microsoft SQL Server\MSSQL10.SQL2008\MSSQL\DATA\Sample.Db_log.ldf', NOUNLOAD, REPLACE, STATS = 10 There is no lock or security issues, the data base doesn't exist on the server. I can't figure it out. Any ideas?

• WSS Web application and IIS Website differences

  - by chaitanya

  Can somebody explain briefly the differences between a "WSS Web Application" and a normal "IIS Website"? I have read that a WSS web application is a "special" IIS Website with WSS featured. I also know that the content of a web application is stored in an SQL Server Website(called the content database) whereas an IIS Website stores it on a hard disk on the server. A point-by-point difference would be appreciated.

• How can you animate a sprite in SFML (C++)

  - by Apoc

  Lets say I have 4 images and I want to use these 4 images to animate a character. The 4 images represent the character walking. I want the animation to repeat itself as long as I press the key to move but to stop right when I unpress it. It doesn't need to be SFML specific if you don't know it, just basic theory would really help me. Thank you.

• How to decouple trac from or align trac with apache authorization

  - by Laizer

  I've had a trac server running for about a year now - chugging along just as expected. Today, I implemented basic authorization on the apache server that trac runs under. Trac now picks up the user as authenticated by Apache, and doesn't allow either logout or a login. I tried to create an apache user with the same name and password as a trac user, but the behavior remained - I can't access trac. How do I align trac with Apache authorization?

• Ruby tutorial for experienced programmers

  - by Skillwired

  I'm looking for a Ruby tutorial which would be usable for Java programmers with 8+ years of experience. I don't need another tutorial which explains basic programing/OOP/OOD concepts (inheritance, polymorphism, encapsulation, classes, constructors, hashes, etc.), just a fast-track tutorial (or even a reference?) which could tell us how to do specific things in Ruby.

• Rails 2 support after Rails 3 has been released

  - by J. Pablo Fernández

  Is there some plan or estimate about how long will Rails 2 be supported after Rails 3 has been released? I wanted to ride the wave and move to Rails 3 right away, specially for projects that may take 4 or 6 months to finish (so that they would probably be released with Rails 3.0.0 final) but I've found many things still not working, many basic plugins and gems; so I believe I'm stuck with Rails 2 for now.

• Generate CSV file from rails

  - by Elliot

  I've been reading similar questions, but many of the answers are outdated or not clear enough for me. I'd like to be able to just do something like (in a controller action): respond_to do |format| format.html format.csv end I know I'd then need a view such as action.csv.erb So my questions are: 1) What do I need to configure in rails to allow this to happen in general. 2) How should I setup the CSV view to display some basic fields from a model?

• Decent simple SQL Server client

  - by John

  Hi, does anyone know of a very simple SQL Server client tool - that does the same basic functions as Management Studio (i.e. choose a database and run a query - doesn't need an Object Explorer, or anything fancy)? Ideally it would be great to have a single exe or zip file version that I could take around on a USB key - anything to avoid installing the full set of SQL Server client tools all the time! Thanks, John

• Online Flowchart Diagram Tool (run from private wiki)

  - by red.october

  Hi, Is there some flowchart diagram tool that would (or could be made to) integrate with a self-hosted wiki? Requirements: basic functionality (e.g., drawing some boxes and some arrows) would strongly prefer it to be visual (i.e., not written out in text that then gets converted) it is important that it can be integrated into the wiki (e.g., as an extra panel somewhere) can be run from a personal server free I've looked around at other threads here concerning a diagram tool, but they are either desktop applications, online ones which reside on third-party servers, or cost money.

• Is drawRect: called on multiple threads when using a CATiledlayer?

  - by Steve Weller

  I know that drawLayer: and drawlayer:inContext: are called on multiple threads when using a CATiledlayer, but what about drawRect:? Apple's PhotoScroller example code uses drawRect: to get its images from disk, and it has no special code for handling threads. I am trying to determine whether my model for a CATiledLayer must be thread-safe.

• Class model for a many-to-many relationship, where relationship has attributes

  - by Greg

  Hi, What would the basic C# code look like to model a many-to-many relationship, where the relationship itself has attributes? And also in this case the many-to-many was referential. So a possible database model for this might look like the following (just to give an example of what I'm talking about) Nodes ID Name Description Relationships Parent_ID Child_ID Relationships_Type

• Help organising controllers logically

  - by kenny99

  Hi guys, I'm working on a site which i'm developing using an MVC structure. My models will represent all of data in the site, but i'm struggling a bit to decide on a good controller structure. The site will allow users to login/register and see personal data on a number of pages, but also still have access to public pages, e.g FAQs, Contact page etc. This is what I have at the moment... A Template Controller which handles main template display. The basic template for the site will remain the same whether or not you are logged in. A main Website Controller which extends the Template Controller and handles basic authentication. If the user is logged in, a User::control_panel() method is called from the constructor and this builds the control panel which will be present throughout the authenticated session. If user is not logged in, then a different view is loaded instead of the control panel, e.g with a login form. All protected/public page related controllers will extend the website controller. The user homepage has a number of widgets I want to display, which I'm doing via a Home Controller which extends the Website Controller. This controller generates these widgets via the following static calls: $this->template->content->featured_pet = Pet::featured(); $this->template->content->popular_names = Pet::most_popular(); $this->template->content->owner_map = User::generate_map(); $this->template->content->news = News::snippet(); I suppose the first thing I'm unsure about is if the above static calls to controllers (e.g Pet and User) are ok to remain static - these static methods will return views which are loaded into the main template. This is the way I've done things in the past but I'm curious to find out if this is a sensible approach. Other protected pages for signed in users will be similar to the Home Controller. Static pages will be handled by a Page Controller which will also extend the Website Controller, so that it will know whether or not the user control panel or login form should be shown on the left hand side of the template. The protected member only pages will not be routed to the Page Controller, this controller will only handle publicly available pages. One problem I have at the moment, is that if both public and protected pages extend the Website Controller, how do I avoid an infinite loop - for example, the idea is that the website controller should handle authentication then redirect to the requested controller (URL), but this will cause an infinite redirect loop, so i need to come up with a better way of dealing with this. All in all, does this setup make any sense?! Grateful for any feedback.
