Subject RE: ADONETAppender and stored procedures
Date Wed, 09 Feb 2005 06:08:12 GMT
Hi Aaron,

I tried your ADONetReturnValueAppender but am getting the error below. Now,
I changed all the private intsnaces in ADONetAppender to protected, as per
your comment in the follow-up email.

Tracing through the source I think the ambigiouity is due to the different
signatured of the AddParameter method in ADONetReturnValueAppender and ADONetValueAppender.
Well, that's my guess anyway. 

public virtual void AddParameter(ADONetReturnValueAppenderParameter parameter);

Is there something else you have changed in ADONetAppender.cs which I may
also need to do?
