  • How to version SQL Server schema using VS 2005?

    - by Mike
    I am new to C# programming and am coming to it most recently from working with Ruby on Rails. In RoR, I am used to being able to write schema migrations for the database. I would like to be able to do something similar for my C#/SQLServer projects. Does such a tool exist for the VS 2005 toolset? Would it be wise to use RoR migrations with SQL Server directly outside of VS 2005? In other words, I would handle all schema versioning using ActiveRecord:Migration from Rails but nothing else. If I do handle migrations outside of C# and VS 2005 with another tool, is RoR ActiveRecord:Migration the best thing to use or is there something which is a better fit?

  • WPF Application with Database.

    - by mike
    Hi, i would like to or need to use a database for my wpf project. It has to store "person" "team" "goals" and maybe 2 more things, nothing very big. Ive already used (worked) with databases in java / php (postgresql), but is there maybe an "easier" way to store the things.. i mean if the db is going to be big than i could use (postgre or mysql), but this one would be small.

  • cocoa - I've discovered what I think is a bug with double numbers...

    - by Mike
    Here is a simple code that shows what I think is a bug when dealing with double numbers... double wtf = 36.76662445068359375000; id xxx = [NSDecimalNumber numberWithDouble: wtf]; NSString *myBug = [xxx stringValue]; NSLog(@"%.20f", wtf); NSLog(@"%@", myBug); NSLog(@"-------\n"); the terminal will show two different numbers 36.76662445068359375000 and 36.76662445068359168 Is this a bug or am I missing something? if the second number is being rounded, it is a very strange rounding btw...

  • NoMethodError in UsersController#create

    - by Mike DeVerna
    I'm getting stuck on an error I'm getting when signing up a new user in Michael Hart's Ruby on Rails Tutorial. I'm new to rails but I've been searching for hours and can't seem to find anything to figure out the issue. My initial thought is that it's specific to the following line: redirect_to @user This is my file for users_controller.rb #!/bin/env ruby # encoding: utf-8 class UsersController < ApplicationController def show @user = User.find(params[:id]) end def new @user = User.new end def create @user = User.new(params[:user]) if @user.save flash[:success] = "Welcome to the Sample App!" ?????????????? redirect_to @user else render 'new' end end end This is the error message I get: NoMethodError in UsersController#create undefined method `??????????????' for # Rails.root: /Users/mikedeverna/Documents/rails_projects/sample_app Application Trace | Framework Trace | Full Trace app/controllers/users_controller.rb:18:in `create' Here is the code in my routes.rb file: SampleApp::Application.routes.draw do resources :users resources :sessions, only: [:new, :create, :destroy] root to: 'static_pages#home' match '/signup', to: 'users#new' match '/signin', to: 'sessions#new' match '/signout', to: 'sessions#destroy', via: :delete match '/help', to: 'static_pages#help' match '/about', to: 'static_pages#about' match '/contact', to: 'static_pages#contact'

  • Do i need a hashtag in Javascript to pass as a Div

    - by Mike
    How do i insert this php DivSomething into Javascript? Since Javascript needs a hashtag to recognize that as a div. Is there a way to tell JS that this is a Div or there's other better way to do it? Any help would be very much appreciated. <script> /*How do i insert a var DivSomething into JS with a hashtag */ /* DivSomething is php dynamic. It returns a Div. It can be #Div1, #Div2, #Div3... */ var DivSomething = '<?php echo $Highlight; ?>' $(function() { $('#MouseHere').hover(function() { $('#' + DivSomething).css('background-color', '#ffffff'); }, function() { // on mouseout, reset the background colour $('#' + DivSomething).css('background-color', ''); </script>

  • Basic CSS question regarding background images for divs

    - by Mike
    I'm a programmer trying to learn some css and I've already run into a stumbling block. I have the following HTML: <div class="container"> <div class="span-24 last"> Header </div> <div class="span-4"> Left sidebar </div> <div class="span-16"> <div class="span-8"> Box1 </div> <div class="span-4"> Box2 </div> <div class="span-4 last"> Box3 </div> <div class="span-16 last"> Main content </div> </div> <div class="span-4 last"> Right sidebar </div> <div class="span-24 last"> Footer </div> </div> In my css I have the following: body { background-color:#FFFFFF; } div.container { background:url(/images/bck.jpg); } I just want to display an image for the background area for the container div but nothing shows up. If I remove the background section from the css and add background-color:#000000; then I see a black background for the container div. What am I overlooking?

  • memcached: which is faster, doing an add (and checking result), or doing a get (and set when returni

    - by Mike Sherov
    The title of this question isn't so clear, but the code and question is straightforward. Let's say I want to show my users an ad once per day. To accomplish this, every time they visit a page on my site, I check to see if a certain memcache key has any data stored on it. If so, don't show an ad. If not, store the value '1' in that key with an expiration of 86400. I can do this 2 ways: //version a $key='OPD_'.date('Ymd').'_'.$type.'_'.$user; if($memcache->get($key)===false){ $memcache->set($key,'1',false,$expire); //show ad } //version b $key='OPD_'.date('Ymd').'_'.$type.'_'.$user; if($memcache->add($key,'1',false,$expire)){ //show ad } Now, it might seem obvious that b is better, it always makes 1 memcache call. However, what is the overhead of "add" vs. "get"? These aren't the real comparisons... and I just made up these numbers, but let's say 1 add ~= 1 set ~= 5 get in terms of effort, and the average user views 5 pages a day: a: (5 get * 1 effort) + (1 set * 5 effort) = 10 units of effort b: (5 add * 5 effort) = 25 units of effort Would it make sense to always do the add call? Is this an unnecessary micro-optimization?

  • Is there a [Go to file...] in Xcode?

    - by Mike
    In every modern day IDE and text editor, there is an action to open a file without putting your hand on the mouse. For example: Eclipse: Cmd|Ctrl+Shift+R - Open Resource IntellIJ: Cmd|Ctrl+Shift+N - Open File TextMate: Cmd+T - Go to File In Xcode, I have found no such options. Please, please tell me I just overlooked it in my growing frustration. Is there a "Go to file" or "Open File" shortcut in Xcode?

  • Adding object to child collection causes entire collection to load in Fluent NHibernate.

    - by Mike C.
    Hello, I have my Parent object, which contains an ICollection of Children objects. The Children are lazy loaded and I do not need them in the context of my scenario. However, when I try to add a new child object to my Children collection, it kicks off the lazy load and loads all 7000 child records. I assume I am making a newbie mistake. Anybody out there know how I can fix this? Thanks!

  • Inter-project dependencies

    - by Mike Hordecki
    Hello! I'm doing some Delphi (2010) work this summer, and I've stumbled upon this problem: My project consists of reusable backend library and a bunch of GUIs that tap into its interface. In this circumstances I've decided to make the backend and GUIs separate projects within single project group (I hope my train of thought is correct). The problem is, how can I include units from the backend in a GUI project? I've tried to modify Project Options > Directories and Conditionals but compiler still complains about being unable to find proper .dcu's. Any ideas? Your help will be appreciated.

  • Why is Harvest being purchased at all?

    - by Mike Caron
    Does your work environment use Harvest SCM? I've used this now at two different locations and find it appalling. In one situation I wrote a conversion script so I could use CVS locally and then daily import changes to the Harvest system while I was sleeping. The corp was fanatic about using Harvest, despite 80% of the programmers crying for something different. It was needlessly complicated, slow and heavy. It is now a job requirement for me that Harvest is not in use where I work. Has anyone else used Harvest before? What's your experience? As bad as mine? Did you employ other, different workarounds? Why is this product still purchased today?

  • How to know if a MySQL UPDATE query fails because information being supplied matches data already in

    - by Mike
    I have a query where the user types a block of text in a textarea field. They are able to save this information in a database. The problem is that if they have not changed the information or if the information matches the data already in the database, I recieve a '0' for affected rows. Usually I display an error that says the query failed when there are no affected rows. How would I 'know' that the 0 affected rows is because the data already exists, so that I can display a more specific error?

  • Header Files Cross Project

    - by Mike
    So I have two projects, A and B, where B is dependent on A (A is a library, while B is a console application). A uses the boost library, and has been configured to include the header and library files, but B has not. Visual studio throws an error saying the Boost Header files cannot be found (in project B). For example: error C1083: Cannot open include file: 'boost/asio.hpp': No Such file or directory [Project: B] My question is: Is there a way such that B does not have to include the Boost library as well?

  • Syncing objects between two devices with different system times

    - by Mike Weller
    Hi there. I'm syncing objects between two devices. Objects have a lastModified property. If both devices have modified an object, then during the next sync the version of the object with the most recent lastModified is chosen on both devices. So we don't do fine-grained merging, only 'most recent version' merging. The problem is this. When one device receives a list of changed objects it can't reliably compare the lastModified of received objects to its own because the system times on the two devices may be different. I considered having each device send its current date/time during the sync. Then each calculates the difference between the remote time and the local time to compare the dates properly. But if there is lag between sending a date and the remote device receiving it, this causes incorrect comparisons with objects that were modified at the same time (or very close together in time). i.e. both devices think the remote object is newer and they end up with different objects. I hope I have explained this clearly enough. There must be a common solution to this kind of problem but my brain isn't coming up with anything. Any suggestions? Thanks in advance...

  • Can you please explain onCreate and Bundles?

    - by Mike
    I have been looking it up and I just cant seem to wrap myself around the onCreate and Bundles. I understand that the onCreate is called when the program starts but its how the Bundles get passed around and how they are pertinent. Can anyone try to put this into plain english because I cant seem to find it well described. Thanks

  • Perl, "closure" using Hash

    - by Mike
    I would like to have a subroutine as a member of a hash which is able to have access to other hash members. For example sub setup { %a = ( txt => "hello world", print_hello => sub { print ${txt}; }) return %a } my %obj = setup(); $obj{print_hello}; Ideally this would output "hello world"

(This is the jquery ui)

  • Array/List/Directory of System.Type

    - by Mike
    I have a lot of classes and want to create some kind of 'directory'. So that I can create menus automatically. Clicking a menu-item would then create an instance of the class and shows the window. What I want for this is an array of System.Type where I can stuff in all the classes without instantiating them. Though from my test and (unsuccessful) googling, this doesn't seem possible. Any ideas?

  • SQL Server Query with "ELSE:"

    - by Mike D
    I have various VB6 projects I'm maintaining with some of the queries being passed to the server having "ELSE:" with the colon used in case statements. I'm wondering can someone tell me what the **ll the colon is used for? It causes errors in SQL2005 and greater, but SQL2000 works with no complaints. I'd like to just remove it from the code & re-compile, but I'm afraid it'll break 10 other things in the application.. Thanks in advance...

    Hi, I recently upgraded my subversion server from 1.4.6 to 1.6.11. The repos all seem to work correctly after this. I then try to upgrade a repo by issuing the svnadmin update command, and it produces no errors and says the update is complete. However, I am unable to open the repository after this. I get the following error when trying to open the repo: Could not open the requested SVN filesystem. I am using Apache, not SVNServe. Any help would be appreciated!
