Like NHibernateAddin, ActiveWriter is an add-in for Visual Studio 2005.
It leverages the DSL functionality to allow you to model classes and relationships and it generates the NHibernate mapping and class files (in VB or C#).
I think this has the potential to meet all my requirements for doing the hard work of class and mapping generation.
Gökhan (the main developer) has done a great job, though his focus is more on C#, so I’ve submitted some bugs (and worked on some patches) to improve the VB side of things.
One thing that is missing at the moment, is that if you drop tables onto the design surface one at a time, they don’t automatically add relations with existing classes. I did discover yesterday that if you drop multiple tables at the same time, it does figure out the relations and add them in.
One of my patches adds support to clean up the class property names. If your database naming strategy means that your column names have some kind of common prefix, you probably don’t want that in the property name.
For example, given the following database table:
CREATE TABLE [dbo].[TEST_CONTENT]
[TC_ID] [int] IDENTITY(1,1) NOT NULL,
[TC_TEST] [int] NOT NULL,
[TC_CONTENT] [int] NOT NULL
If you set the model’s “Property Name Filter Expression” property to the regular expression
^\w+?_ it will then remove the text up to the first underscore for each property name, so that you end up with a class like this:
- Add relations when dropping additional tables
- Support for custom types for properties
- Auto-arrange model layout
I was looking at some T-SQL that RJ had written and noticed he was using ‘True’ and ‘False’ when dealing with bit data types.
I’ve always used 1 and 0, but I think ‘True’ and ‘False’ is more obvious, and I think I’ll start using it from now on.
Sure enough, the SQL 2005 Books Online entry for bit (Transact-SQL) mentions this:
The string values TRUE and FALSE can be converted to bit values: TRUE is converted to 1 and FALSE is converted to 0.
With some recent birthdays, we’ve acquired some computer games for the kids to play.
The titles include:
- Arthur’s Wilderness Rescue
- Arthur’s Sand Castle Content
- Arthur’s Pet Chase
- Discovering Dinosaurs
- Phonics 1 for beginners
Even though these games are quite engaging and the kids really seem to like them, it’s amazing at how clumsy some of these applications are to get installed in a ‘safe’ way.
I install them myself, and then set up shortcuts so that the kids can log in using their username. I am an admin on our home pc, but the other accounts are just regular users.
The games expect to run as Administrator (eg. the “Arthur” titles try and write the saved games back to the Program File installed directory (instead of in the user’s profile). As a consequence, I had to fire up cacls.exe to grant Everyone permission to write to this folder.
They also seem to assume you have a VGA monitor - when they try and change the resolution it doesn’t always look that good on a LCD display.
They also often require the CD to be in the CD-ROM drive. I find this particularly annoying. The installation should allow me to install everything from the drive onto the hard disk so you don’t need to be swapping CD’s.
I’m trying to work around this by generating an ISO image of the CD using ISO Recorder, and then mounting and unmounting the image when you want to run the game.
I found FileDisk - a Windows driver and command-line tool to mount and unmount ISO files. I then created a small batch file that I thought should do the job:
REM mount cd
“C:\bin\filedisk.exe” /mount 1 “c:\Install\ISO\ArthurWildernessRescue.iso” /cd e:
cd “C:\Program Files\The Learning Company\Arthur’s Wilderness Rescue\Launcher”
“C:\Program Files\The Learning Company\Arthur’s Wilderness Rescue\Launcher\TLCLauncher.exe”
"C:\bin\filedisk.exe" /umount e:
I then tried this out with one of the non-admin logins, but sadly it fails with an “access denied” error. It appears that filedisk is using one of the Win32 API calls assuming the current user is an Administrator too.
Filedisk does include source code, so it might be possible to fix this, but I’m guessing it might take a bit of time to figure it out.
Taking “Arthur’s Wilderness Rescue” as an example, I looked closer at what files it had left on the CD, and it didn’t appear to be many at all!
I located a file “salstartup.xml” and noticed that it was pointing to a file on the CD, so I copied this file onto the hard disk and updated the XML file and it appears that it all works now without the CD being in the drive.
If you like the multi-monitor desktop wallpaper support provided by UltraMon but can’t afford USD39.95, you could either write your own, or you could check out Binary Fortress Software’s DisplayFusion.
I trialled UltraMon for 30 days, and I really like the extended task bar that they provide too.
