Writing ADO custom providers

Hi,

We have a DOS based ISAM style database format and need to access this data
via ADO. Can anyone point me toward information that will help me write an
ADO data provider so that we can access this information using ADO.NET?
 
Is there an ODBC driver for this database? If so, just access it via the
Odbc .NET Data Provider. If not, you might find it easier to convert the
database to a more standard format.

What database is it...?
 
Firebird is an open source project and they have their own provider..
You might check there.
 
oh yes, I have been talking about upgrading for 10 years or more,
unfortunatley it's not my decision. This is why I intend to write a provider
to enable a relatively smooth transition from the DOS product to a new
Windows/Web based product while retaining the database, then when the GUI is
complete we can port the database to client-server - the only other
alternative is to rewrite the application from scratch which is likely to be
a 2 year project with massive risk and upgrade headaches, which is why it
hasn't been done yet
 
Chapter 15 of my first book demonstrates writing a provider for MSMQ - you
can use the same concepts atleast for .NET 1.1.
