You need to have MySql.Data.dll in the same directory as DbMetal.exe.

Alternatively, you need to edit DbMetal.exe.config to contain the full assembly-
qualified type name for the MySQL provider.

If you're running from the `build` directory after building with MSBuild and/or 
Visual Studio, then there should be a MySql.Data.dll in the same directory as 
DbMetal.exe.  (If not, you can copy the one from the `lib` directory).  
Otherwise, 
you need to ensure that when you copy DbMetal.exe to an "alternate" directory 
that 
you ALSO copy all the "dependent" files (DbMetal.exe.config, DbLinq.MySql.dll, 
MySql.Data.dll, possibly others).

Where are you running DbMetal.exe from, and does that directory contain the 
necessary 
files?

I downloaded DbLinq-0.19 directly from the website, unzipped it to a folder on 
the
desktop and made a bat file.

The files in the directory are as follows:
 Volume in drive C has no label.
 Volume Serial Number is DCD2-04CF

 Directory of C:\Users\Administrator\Desktop\DbLinq-0.19

As you can see there is no MySql.Data.dll as it was not in the zipfile, and I 
have
found no tutorial or description of how to use DBMetal that explains that I 
should
have downloaded that file in order to get it work. Maybe these kind of 
exceptions
should be caught and an more descriptive/suggesting error message should be 
shown to
the user, just a suggestion.

I have d/l the needed ddl file but is now getting another error, but that 
properly
have to do with security restrictions at my current location. I'll try later 
on. This
issue can be closed, but you should think about writing an article or tutorial 
of how
to use DbLinq/DbMetal in step by step with all requirements listed so anyone can
figure it out :-)

I obviously need to write some documentation... :-/

Regardless, the logic is this:

    http://groups.google.com/group/dblinq/msg/2981c81492fcf32a

The binary .zip doesn't contain MySql.Data.dll (or any other ADO.NET 
providers); you 
need to provide them, as (presumably) you have a valid license to the DB that 
you'll 
be using and a pre-existing set of ADO.NET providers.  Just drop them into the 
same 
directory as DbMetal.exe and things should (hopefully) Just Work.

And behold, some documentation: 
http://code.google.com/p/dblinq2007/wiki/Installation

If that needs any clarification, please let me know so that I can fix it.

Thanks!

Thanks for your help.
