try this:
HMUser[] hmUser = HMUser.FindAll( Expression.Eq("UserName", txtUsername),
Expression.Eq("Password", txtPassword.Text)});
read this criteria as "Expression.Eq("UserName", txtUsername) AND
Expression.Eq("Password", txtPassword.Text)"
if you want logical disjunction (fancy name for OR) you need:
Expression.Or(
Expression.Eq("UserName", txtUsername),
Expression.Eq("Password", txtPassword.Text)
) // obviously wrong for this use case
regarding exception, have you registered all active record types (also the
derived ones)?
Here is how you can register all AR types inside the assembly:
ActiveRecordStarter.Initialize(typeof(BaseHM).Assembly,
ActiveRecordSectionHandler.Instance);
