Connecting to an Ingres database

I'm having trouble connecting to an Ingres database on my local machine through the Ideablade object mapper. Ideablade passes the Test connection, but when it comes time to add the classes in, I get an unable to connect error.

I can connect and query in my .Net code using the System.Data.Odbc objects with a plain connection string (pasted below), and with a prebuilt ODBC connection.

Provider=MSDASQL.1;DRIVER=Ingres;SRVR=(local);DB=demodb;Persist Security Info=True;SELECTLOOPS=N;

So far the only data provider in the list I've had any luck with is "Microsoft OLEDB Provider for ODBC Drivers", am I wrong to assume there should be an Ingres driver here that I could be missing?

Many thanks,
Keith

Thanks for your reply David, I do remember reading somewhere in my research that IdeaBlade can support ingres, but I now realise that I was reading about the EF version (linked). http://www.ideablade.com/DevForceEF/ProductDocumentation/DevForceEFInstallationGuide.html

Would it be easier for me to hook into ingres using EF or am I at the same stumbling block?

Thanks muchly, you've been most helpful. I'll have to keep an eye on the Entity framework as I do quite a bit of integration work which often includes some very interesting databases that need to be compared to sql server data

Cheers,
Keith
