At the risk of appearing a dinosaur, I have some old C++ code, compiled with Borland C++, which sets registers, and interfaces to an Assembler module, which I would like to modernize. I have just installed MS VC++ Express, and needless to say a lot of things don't work! The default seems to be Win32, which is fine, so I have blanked out...
I am using migrator.net to handle database migrations for SQL Server, and I like it so far. The only issue I've run into is how best to migrate changes to views.

I ran "rake db:migrate" to re-sync schema.db with my database schema. But it failed, saying that one of my tables already exists. I think it was trying to re-create the table. If you just want to get schema.rb updated to reflected any changes you made in the database independently of Rails, what command should you use if not "rake db:mig...

(for example, I remeber that after migrating from 2000 to 2005, one linked server we had to a sql 6.5 server ...
In Rob Conery's post about SubSonic Migrations written in October 2007 he mentions in the 'Left To Do' list that: I want to be able to “Reverse Engineer” an existing DB into a migration file I am looking at introducing versioning control for an existing database with a lot tables, and SubSonic looks like the tool for me, but I'...
Quick summary: I have a Rails app that is a personal checklist / to-do list. Basically, you can log in and manage your to-do list. My Question: When a user creates a new account, I want to populate their checklist with 20-30 default to-do items. I know I could say: wash_the_car = ChecklistItem.new wash_the_car.name = 'Wash and wax the ...

There's some info on how to do this process on a Linux box (hgsvn) I don't have a Linux machine available. Can I use those python scripts on windows? If so, wha...
I have several (20-30) Flash files that I need to migrate from AS2 to AS3. The biggest issue that I'm having is that it's extremely tedious to go through all the code and change the places where the code is on the buttons to an event handler model. I'm not hopeful, but I was wondering if anyone knew of any tricks or tools to quickly ch...
