Thanks Zdeslav!
The code closest to your code I can write without having compiling
errors is this:
HMUser[] hmUser = (HMUser[]) HMUser.FindAll(
Expression.Eq("UserName", txtUsername),
Expression.Eq("Password", txtPassword.Text));
I must typecast it to HMUser[] because HMUser.FindAll will return
BaseHM. And when I run this code I got an exception in runtime that I
have described previously in this thread.
And I have added all my classes to the Initialize method in my
global.asax. Have also tried your suggestion. :(

You have accessed an ActiveRecord class that wasn't properly
initialized. The only explanation is that the call to
ActiveRecordStarter.Initialize() didn't include HMBackend.BaseHM
class
