Hi All,

I have a legacy ADOCE dll that I need to get working with
an application that uses ADO.NET.

We use this legacy component for database access... Is
there any way to work ADOCE with ADO.neet?

thanks,
Fred

Possibly. Is this a COM based component or Windows DLL? What data types are used for your function
call arguments?

Hi Paul,

Thiis is a Windows DLL and we basically pass a SQL string
to the component and it returns a Recordset. Like GetRows.

Thanks,
Fred.

Yes, many DLLs can be wrapped (VS.NET will do this for you) in a COM interop
layer. When it arrives you should be able to access the Recordset using COM
Interop wrapped ADO classic. Would I recommend this approach? Nope. I would
re-write the DLL to return a DataSet.

Sounds like it should be possible. First I'm assuming that this is a 32-bit DLL and you're returning
an ADODB.Recordset object. If this is the case then you can either stick with ADO, using COM
Interop, or simply dump the returned ADODB.Recordset contents into an ADO.NET DataSet using the
OleDbDataAdapter Fill method.
