  • Handle CSliderCtl messages placed on a CDialogBar

    - by user173438
    VS2008, 32 Bit Win XP In a class derived from CFrameWnd, I have an object of CDialogBar that needs to have certain controls on it. Among these controls would be 2 sliders, whose event handling is to be done in CFrameWnd derived class. How shall I go about this? class CFrameWndCustom : public CFrameWnd { CDialogBar m_wndDialogBar; // the CDialogBar object. } In CFrameWnd derived class's OnCreateClient, I have created the DialogBar using the above object like: //Create the DialogBar if (!m_wndDialogBar.Create(this, IDD_DIALOGBAR_CONTROL, CBRS_BOTTOM, IDD_DIALOGBAR_CONTROL)) { TRACE("Warning: Couldn't create DialogBar Control!\n"); return FALSE; } Here, IDD_DIALOGBAR_CONTROL is a dialog resource with Style as Child. After this, I drag-dropped a CSliderCtrl on the IDD_DIALOGBAR_CONTROL in Resource View. Now, how/where should I handle the CSliderCtrl's events? There would be 2 such slider controls. I finally need the values of the sliders in CFrameWndCustom class. best regards, Divya

  • Can I delete a differential backup from SQL Server 2005?

    - by BlueMonkMN
    I often like to create backups when testing the software I work on, and will sometimes create a differential backup if I want to be able to get back to multiple previous states. However, sometimes I realize that I forgot one thing I wanted to include in a differential backup, or I no longer need a previous differential backup. Sometimes I simply want to create a new scenario from the original base image and start working with a new series of differential backups. So I'd like to be able to delete some older differential backups so I don't get confused about which ones I'm using. But I can't find any way to delete just the differential backups, selectively or all at once.

  • Rails associations of user/post/comment

    - by garthcn
    Hi, I'm trying to create an app like a blog, with 3 models: user, post and comment. As expected, a comment belongs to both a user and a post. I used the following associations: User.rb has_many :comments has_many :posts Post.rb has_many :comments belongs_to :user Comment.rb belongs_to :user belongs_to :post And I tried to create comments using: @user.comments.create However, this will relate the comment with user, but not with post. I want the comment to be associated wit BOTH user and post. Is there a way to do so? Or did I use the wrong associations? I think it might be a bad practice to set the user_id or post_id by hand, so both ids are not in attr_accessible. I'm not sure if it is correct. Thank you!

  • creating events in my classes, and allowing others to hook into them in my django app

    - by Blankman
    I want to create events for my classes. Say I create a CMS application that has a Article object. I create events like: OnEdit OnCreate OnDelete PreCreate PreDelete Now I want someone to be able to hook into these events, and add their custom functionality at each event they wish. I don't want them touching the core source code, so they would have to wire these custom methods to fire somewhere else. I'm new to both python and django so please be as detailed as possible if you can.

  • Sharing base object with inheritance

    - by max
    I have class Base. I'd like to extend its functionality in a class Derived. I was planning to write: class Derived(Base): def __init__(self, base_arg1, base_arg2, derived_arg1, derived_arg2): super().__init__(base_arg1, base_arg2) # ... def derived_method1(self): # ... Sometimes I already have a Base instance, and I want to create a Derived instance based on it, i.e., a Derived instance that shares the Base object (doesn't re-create it from scratch). I thought I could write a static method to do that: b = Base(arg1, arg2) # very large object, expensive to create or copy d = Derived.from_base(b, derived_arg1, derived_arg2) # reuses existing b object but it seems impossible. Either I'm missing a way to make this work, or (more likely) I'm missing a very big reason why it can't be allowed to work. Can someone explain which one it is? [Of course, if I used composition rather than inheritance, this would all be easy to do. But I was hoping to avoid the delegation of all the Base methods to Derived through __getattr__.]

  • MySQL: Query to obtain recipes using all given ingredients.

    - by John_A
    hi I have the following simplified tables: CREATE TABLE recipe(id int, name varchar(25)); CREATE TABLE ingredient(name varchar(25)); CREATE TABLE uses_ingredient(recipe_id int, name varchar(25)); I want to make a query that returns all id's of recipes that contain both Chicken and Cream. I have tried SELECT recipe_id FROM uses_ingredient INNER JOIN (SELECT * FROM ingredient WHERE name="Chicken" OR name="Cream") USING (name) GROUP BY recipe_id HAVING COUNT(recipe_id) >= (SELECT COUNT(*) FROM theme); which gives me :"ERROR 1248 (42000): Every derived table must have its own alias" and is probably wrong too. Next I tried SELECT recipe_id FROM (SELECT * FROM ingredient WHERE name="Chicken" OR name="Cream") AS t INNER JOIN uses_ingredient USING (name) GROUP BY recipe_id HAVING COUNT(recipe_id)>= (SELECT COUNT(*) FROM t); which gives "ERROR 1146 (42S02): Table 'recipedb.t' doesn't exist" I want to avoid creating temporary tables including using ENGINE=MEMORY.

  • Do Portable Class Libraries work with .net 3.5?

    - by Eric
    I am running Windows 8 and have both Visual Studio 2010 Ultimate w/sp1 and Visual Studio 2012 Ultimate and I am trying to create a Portable Class Library that supports .net 3.5 and greater. When I first try to create a PCL I get a screen like this: I noticed that .net 3.5 is not in the list so I clicked on "Install additional frameworks" and found a Targeting Pack for version 3.5. But when I download and run "dotnetfx35setup.exe" nothing happens. And when I go back into VS and try to create a new Portable Class Library, it lists the same target frameworks as before. I have also turned on the Windows Features for .NET Framework 3.5 and am now out of ideas. Here is a screen shot in case I missed something else. Thanks,

  • How do you set the default user in Linux for file creation?

    - by Not a Name
    I want to create a directory, for example: /public/all But I want it so that if you create a file in all, the owner is root, but anyone with access to the /public/all folder can delete/edit/etc the file, just not change the permissions. (I will use a self-created "setx" application to change the execute value if needed.) Reason for this, I don't want you to be able to deny other users write/read access to files in /public/all. I heard setuid on directories doesn't work for that.

  • How to design a database schema for storing text in multiple languages?

    - by stach
    We have a PostgreSQL database. And we have several tables which need to keep certain data in several languages (the list of possible languages is thankfully system-wide defined). For example lets start with: create table blah (id serial, foo text, bar text); Now, let's make it multilingual. How about: create table blah (id serial, foo_en text, foo_de text, foo_jp text, bar_en text, bar_de text, bar_jp text); That would be good for full-text search in Postgres. Just add a tsvector column for each language. But is it optimal? Maybe we should use another table to keep the translations? Like: create table texts (id serial, colspec text, obj_id int, language text, data text); Maybe, just maybe, we should use something else - something out of the SQL world? Any help is appreciated.

  • Sharing Code, Images and Core Data models across iPhone and Mac project

    - by Robert
    Hi, I am maintaining a fairly large mac project and an iphone client for this project. Some code as well as some images and core data models are shared between these two projects. I want to create a shared framework containing this shared components but to my surprise, frameworks like we cocoa developers known them are not supported on the iphone os. Currently I see the following options: a) Include the files in both projects (much tedious work) b) Create a static library for both projects and manually copying the images/core data models c) Create a static lib for iphone and a framework for mac Any suggestions?

  • global counter in application: bad practice?

    - by Martin
    In my C++ application I sometimes create different output files for troubleshooting purposes. Each file is created at a different step of our pipelined operation and it's hard to know file came before which other one (file timestamps all show the same date). I'm thinking of adding a global counter in my application, and a function (with multithreading protection) which increments and returns that global counter. Then I can use that counter as part of the filenames I create. Is this considered bad practice? Many different modules need to create files and they're not necessarily connected to each other.

  • Creating Oracle stored procedure that returns data

    - by user3614327
    In Firebird you can create a stored procedure that returns data an invoke it like a table passing the arguments: create or alter procedure SEL_MAS_IVA ( PCANTIDAD double precision) returns ( CANTIDAD_CONIVA double precision) as begin CANTIDAD_CONIVA = pCANTIDAD*(1.16); suspend; end select * from SEL_MAS_IVA(100) will return a single row single column (named CANTIDAD_CONIVA) relation with the value 116 This is a very simple example. The stored procedure can of course have any number of input and output parameters and do whatever it needs to return data (including multiple rows), which is accomplished by the "suspend" statement (which as it name implies, suspends the SP execution, returns data to the caller, and resumes with the next statement) How can I create such kind of stored procedures in Oracle?

  • Binary diff/patch for large files on linux?

    - by thejh
    I've got two partition images (A and B) and want to use them to create a patch that I can apply on A on another computer in order to get the new B image without flooding the network. I have the following requirements: works on linux can create diffs can use diffs to patch files can handle binary files can handle large files (a few hundred GB should work) no user interaction required (just a console application) ideally, should be able to read from/write to pipes (so that I can pipe into it from a gzip-compressed file and write to one) Does something like that exist?

  • Time for creation of database on site

    - by slo2ols
    Hi. When and where would you create database to develop web site using ASP.NET MVC 2 and Entity Framework 4 (CreateDatabase method). I think about first run of web site and redirect on welcome page, when controller creates database from model. But I doubt about details: 1. Where? In HttpModule, but request of any image or css will check that database exist. In custom RouteHandler, but then anybody need to know that need to use this handler when to add route. In BaseController, but then code will look like SomeController(..., IDatabase database) : base(database). 2. When? Better create database on first run by any url or may be on deployment of site (additional tool which create ObjectContext and invoke CreateDatabase)? Thanks.

  • How do I inherit abstract unit tests in Ruby?

    - by Graeme Moss
    I have two unit tests that should share a lot of common tests with slightly different setup methods. If I write something like class Abstract < Test::Unit::TestCase def setup @field = create end def test_1 ... end end class Concrete1 < Abstract def create SomeClass1.new end end class Concrete2 < Abstract def create SomeClass2.new end end then Concrete1 does not seem to inherit the tests from Abstract. Or at least I cannot get them to run in eclipse. If I choose "Run all TestCases" for the file that contains Concrete1 then Abstract is run even though I do not want it to be. If I specify Concrete1 then it does not run any tests at all! If I specify test_1 in Concrete1 then it complains it cannot find it ("uncaught throw :invalid_test (ArgumentError)"). I'm new to Ruby. What am I missing here?

  • Rails subscription limitations

    - by David Lyod
    I have an application with set limits on subscription attributes i/e a user can have five projects for subscription A but have ten for subscription B At present I run a check on there current usage when linking to the create action and if they are over there limit I do not display the link to create a new project. On the view (for the new project ) I again run the check (in a helper) to see if they can create a new project and if they are not I display a message stating so and a little upgrade link. Is this a secure method of stopping a user bypassing there subscription attribute limitations ? What about direct PUT requests etc ?
