• How to override event on a UserControl

  - by Vadim

  Hello! I have a WinForms application (OwnerForm) with some UserControl. When textbox of UserControl is changed, I want to filter content of a OwnerForm. But how can I make it? I don't want to specify OwnerForm inside the user control. I know a solution to add manually handlers for MyUserControl.tb.TextChanged to some functions on a owner form, but I think it's bad way. I'll prefer to have overridable functions, but I can't imagine how to do it. Any suggestions? Thanks in advance,

• Dynamic/Generic ViewModelBase?

  - by Shimmy

  I am learning MVVM now and I understand few things (more than but few are here..): Does every model potentially exposed (thru a VM) to the View is having a VM? For example, if I have a Contact and Address entity and each contact has an Addresses (many) property, does it mean I have to create a ContactViewModel and an AddressViewModel etc.? Do I have to redeclare all the properties of the Model again in the ViewModel (i.e. FirstName, LastName blah blah)? why not have a ViewModelBase and the ContactViewMode will be a subclass of ViewModelBase accessing the Entity's properties itself? and if this is a bad idea that the View has access to the entity (please explain why), then why not have the ViewModelBase be a DynamicObject (view the Dictionary example @ the link page), so I don't have to redeclare all the properties and validation over and over in the two tiers (M & VM) - because really, the View is anyway accessing the ViewModel's fields via reflection anyway. I think MVVM was the hardest technology I've ever learned. it doesn't have out-the-box support and there are to many frameworks and methods to achieve it, and in the other hand there is no arranged way to learn it (as MVC for instance), learning MVVM means browsing and surfing around trying to figure out what's better. Bottom line, what I mean by this section is please go and vote to MSFT to add MVVM support in the BCL and generators for VMs and Vs according to the Ms. Thanks

  im trying to create an image filter in OpenGL CE. currently I am trying to create a series of 4x4 matrices and multiply them together. then use glColorMask and glColor4f to adjust the image accordingly. I've been able to integrate hue rotation, saturation, and brightness. but i am having trouble adding contrast. thus far google hasn't been to helpful. I've found a few matrices but they don't seem to work. do you guys have any ideas?

• WinForms / .Net interactive world map - how?

  - by FerretallicA

  In a CD collection program, I have each artist's country of origin stored in the main database and want to display a map of the world which: Colour-codes each country depending on the number of CDs by artists in that country Allows clicking on each country to filter a list of CDs to only ones by artists in that country This is a heavily simplified version of what I'm trying to do, but if I can at least get this far the rest should be easy enough to figure out. So far the closest thing I've found to what I'm trying to do is here: http://www.synergetechsolutions.com/blog/analytics-world-map-control Ideally I don't want to be embedding Flash in my program though, and the only other solutions I've found all involve SVG which I haven't managed to get working in practice outside of a web browser control (and I DEFINITELY don't want to be embedding a browser in the forms). Something in pure managed code and either GDI+ or WPF would be preferable. Are there any existing components that would get me started, or can anyone suggest how to approach it from scratch?

  what is the next best thing to use when you want to select the next li item, but not the one that has someClassName.

• Design: How to declare a specialized memory handler class

  - by Michael Dorgan

  On an embedded type system, I have created a Small Object Allocator that piggy backs on top of a standard memory allocation system. This allocator is a Boost::simple_segregated_storage< class and it does exactly what I need - O(1) alloc/dealloc time on small objects at the cost of a touch of internal fragmentation. My question is how best to declare it. Right now, it's scope static declared in our mem code module, which is probably fine, but it feels a bit exposed there and is also now linked to that module forever. Normally, I declare it as a monostate or a singleton, but this uses the dynamic memory allocator (where this is located.) Furthermore, our dynamic memory allocator is being initialized and used before static object initialization occurs on our system (as again, the memory manager is pretty much the most fundamental component of an engine.) To get around this catch 22, I added an extra 'if the small memory allocator exists' to see if the small object allocator exists yet. That if that now must be run on every small object allocation. In the scheme of things, this is nearly negligable, but it still bothers me. So the question is, is there a better way to declare this portion of the memory manager that helps decouple it from the memory module and perhaps not costing that extra isinitialized() if statement? If this method uses dynamic memory, please explain how to get around lack of initialization of the small object portion of the manager.

• In SQL Server merge replication, how does reinitializing work?

  - by Craig Shearer

  I have set up a pull subscription to a merge publication in SQL Server. I use parameterized row filters on some tables. This works fine with the initial synchronization - just the rows using the filter arrive in the replicated (client) database. However, at some later point I'd like to be able to synchronize the replicated database again from the server and have new rows that match the parameterized row filters appear on the client database. The doucmentation seems to indicate that I can call Reinitialize() to do this. However, when I do try this and Synchronize again, I get an error saying that the script 'snapshot.pre' cannot be applied to the database. I've inspected the script and can see why - it's trying to drop some functions are used by the tables in the database. It would appear that for Reinitialize() to work it requires that the database be blank. Am I misunderstanding something here? Is there a way to make this work?

• Configuration for log4j to log ERROR level to a DB table

• Possible to capture the returned value from a Python list comprehension for use a condition?

  - by Joe

  I want to construct a value in a list comprehension, but also filter on that value. For example: [expensive_function(x) for x in generator where expensive_function(x) < 5] I want to avoid calling expensive_function twice per iteration. The generator may return an infinite series, and list comprehensions aren't lazily evaluated. So this wouldn't work: [y in [expensive_function(x) for x in generator where expensive_function(x)] where y < 5] I could write this another way, but it feels right for a list comprehension and I'm sure this is a common usage pattern (possible or not!).

• Getting Google Chrome to Ignore IE Javascript

  - by swajak

  I'm creating a slideshow using javascript that fades images. Awhile back, I discovered that to change the opacity of an image, I have to use a different API, depending on whether the page is viewed in Firefox or IE. Firefox: img.style.opacity = [value 0 to 1]; IE: img.style.filter="progid:DXImageTransform.Microsoft.Alpha(opacity= [value 0 to 100] )"; So, currently, I use <script LANGUAGE="JScript"> for code that is meant for IE. This was suggested in the Mozilla docs. The problem: Chrome thinks my <script LANGUAGE="JScript"> code is valid, when it is not. How to make Chrome ignore the code inside <script LANGUAGE="JScript"> ? Or how to make my opacity code cross-browser?

• How do I request a single random row from a force.com database in SOQL?

  - by Ollie C

  Total row-count is in the range 10k-100k rows. Can I use RAND() on force.com? Unfortunately although all the rows have a unique numeric identifier, there are many gaps, and I'd often want to select a random row from a filtered subset anyway. I suspect there's no particularly efficient way to do this, but is it possible at all? Ultimately all I want to do is to extract one row from a table (or a subset based on specific filter criteria) at random. If force.com doesn't let me select a random row, then can I query the rows to select from, and assign sequential IDs to all the rows, say 1-1,035, and then select a random number in that range locally, say 349, and then get row 349?

• Yet another Rails routing question

  - by danhere

  I can't seem to grasp the Rails routing just yet. I want to be able to link the site to, for example, ...com/store/xbox360/Mass Effect 2 (which is /store(my controller)/:system/:title). I have the database entries that include the :system and :title variables (?). How would I route these to show up and filter these entries? Or is this something I need to set up in the controller? I'm lost. Thanks so much for your help.

• Facelets charset problem

  - by Vladimir

  Hi! In my earlier post there was a problem with JSF charset handling, but also the other part of the problem was MySQL connection parameters for inserting data into db. The problem was solved. But, I migrated the same application from JSP to facelets and the same problem happened again. Characters from input fields are replaced when inserting to database (c is replaced with Ä), but data inserted into db from sql scripts with proper charset are displayed correctly. I'm still using registered filter and page templates are used with head meta tag as following: <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-2"> If I insert into h:form tag the following attribute: acceptcharset="iso-8859-2" I get correct characters in Firefox, but not in IE7. Is there anything else I should do to make it work? Thanks in advance.

• javascript and extJs - scope question

  - by ben

  Hi guys, I got a little scope related problem with some js code, maybe somebody can explain to me what I'm making wrong: I'm using extJs and got this snippet: Ext.onReady(function(){ // Form for filter selection var formFilter = new Ext.FormPanel({ // ... items: [ cbGroup = new Ext.form.ComboBox({ fieldLabel: 'Group', store: dsGroups, displayField: 'name', valueField: 'number', emptyText : '- Please choose a group -', listeners:{ 'select': function() { alert(cbGroup.selectedIndex +' '+this.selectedIndex); } } }) ] }); }); The problem: When I access the combobox over 'this' within the listener function, I get the correct result for the selectIndex property. When I access the combobox over it's var name, I allways get the result '-1'. Thank a lot for your help!

• How to create project specific respository post-commit actions

  - by Pacifika

  Presently, we've got several main projects each in their own repository. We will have to version-control up to a dozen additional projects. VisualSVN recommends to create 1 respository for our company and then vc all projects inside that. It's a good practice to create one repository for the entire company or department and store all your projects in this repository. Creating separate repository for each project is not a good idea because in that case you will not be able to perform Subversion operations like copy, diff and merge cross-project. VisualSvn.com Currently we're using post-commit hooks to update the testing server with the latest commit and do other project specific actions (such as emailing certain people for one project but not for others) depending on which project has been committed. As post-commit runs for the whole repository, is this still possible in such a situation? How would I go about decerning which project has changes? filter folder structure?

• c++ Design pattern for CoW, inherited classes, and variable shared data?

  - by krunk

  I've designed a copy-on-write base class. The class holds the default set of data needed by all children in a shared data model/CoW model. The derived classes also have data that only pertains to them, but should be CoW between other instances of that derived class. I'm looking for a clean way to implement this. If I had a base class FooInterface with shared data FooDataPrivate and a derived object FooDerived. I could create a FooDerivedDataPrivate. The underlying data structure would not effect the exposed getters/setters API, so it's not about how a user interfaces with the objects. I'm just wondering if this is a typical MO for such cases or if there's a better/cleaner way? What peeks my interest, is I see the potential of inheritance between the the private data classes. E.g. FooDerivedDataPrivate : public FooDataPrivate, but I'm not seeing a way to take advantage of that polymorphism in my derived classes. class FooDataPrivate { public: Ref ref; // atomic reference counting object int a; int b; int c; }; class FooInterface { public: // constructors and such // .... // methods are implemented to be copy on write. void setA(int val); void setB(int val); void setC(int val); // copy constructors, destructors, etc. all CoW friendly private: FooDataPrivate *data; }; class FooDerived : public FooInterface { public: FooDerived() : FooInterface() {} private: // need more shared data for FooDerived // this is the ???, how is this best done cleanly? };

• setting page access permissions in drupal

  - by Nikhil Patil

  I'm new to drupal. Its a very dumb question I guess. I have enabled PHP filter module so that I can create a new page with my own PHP code in it. This particular page I want to be accessible to only authenticated users, not visible to anonymous users. How can I achieve this? Can I set permissions for individual pages in drupal? Or is it possible to identify that an anonymous user is trying to access the current page through PHP code?

• how to deal with a static analyzer output

  - by Jim

  We have started using a static analyzer (Coverity) on our code base. We were promptly stupefied by the sheer amount of warnings we received (its in the hundreds of thousands) , it will take the entire team a few mounts to clear them all (obliviously impossible). the options we discussed so far are 1) hire a contractor to sort out the warning and fix them - he drawback: we will probably need very experiences people to do all these modifications, and no contractor will have required understanding of the code. 2) filter out the warning and deal only with the dangerous ones - the problem here is that our static analysis output will always be cluttered by warning making it difficult for us to isolate problems. also the filtering of the warning is also a major effort. either way, bringing our code to a state when the static analyzer can be a useful tool for us seems a monumental task. so how is it possible to work with the static analyzer without braining current development efforts into a complete stand still?

• Getting started with open source

  - by lola

  Hi all, I'm an undergraduate who has decided that he wants to join the open source community and contribute. However, I have come to think that, once you have chosen an open source project, a lot of time is spent in learning the nitty gritties of that project in addition to stuff like subversion,etc which a typical undergraduate isn't exposed to. So, you have to stick with that project for a long time, say a year or two, before moving on to other projects. In this case, choosing the right(for you) initial project is very important since if you choose one,and say, the development in your field of interest(in that project) is a low priority and not exciting enough, you'll lose interest and stop contributing to open source all together. So what I wanted to know was, since there are thousands of open source projects, is all this being documented somewhere with tags,etc so that a beginner can choose his projects. The GSoc 2010 ideas list is a great starting point, but it only covers a handful. Hence, I thought why not ask this at stackoverflow: if you have any pointers as to where to start, when choosing a FOSS project or any other tips related to starting with FOSS. P.S. I'm interested in projects involving mobile ad hoc networks(those using TinyOS, preferably), so pointers related to these will be great. I'm looking through Freifunk and OLPC as of now, needed more ideas.

• require_owner code to limit controller actions not recognizing current user as owner

  - by bgadoci

  I am trying to restrict access to certain actions using a before_filter which seems easy enough. Somehow the ApplicationController is not recognizing that the current_user is the owner of the user edit action. When I take the filter off the controller correctly routes the current_user to their edit view information. Here is the code. Link to call edit action from user controller (views/questions/index.html.erb): <%= link_to "Edit Profile", edit_user_path(:current) %> ApplicationController (I am only posting the code that I think is affecting this but can post the whole thing if needed). class ApplicationController < ActionController::Base def require_owner obj = instance_variable_get("@#{controller_name.singularize.camelize.underscore}") # LineItem becomes @line_item return true if current_user_is_owner?(obj) render_error_message("You must be the #{controller_name.singularize.camelize} owner to access this page", root_url) return false end end and the before_filter class UsersController < ApplicationController before_filter :require_owner, :only => [:edit, :update, :destroy] #... end I simply get the rendering of the error message from the ApplicationController#require_owner action.
