I have added a new field to the MM_Secur.Users table to store an Init Vector. So I overloaded the mmUser class with my own class called JdaUser and I added a public member to store info for this field.

public class JdaUser : mmUser	{
	public string InitVecField;

Then I changed my Factory class to override the CreateUserObject() method so that it returns my JdaUser object.

public override mmUser CreateUserObject()
{
	return new JdaUser();
}

I have tried instantiating my JdaUser object with CreateUserObject() 2 different ways and they both give me compile-time errors.

1. Since CreateUserObject() actually returns a JdaUser object, I defined my variable as JdaUser. This gives me an error: "Cannot implicitly convert type 'OakLeaf.MM.Main.Security.mmUser' to 'Jda.Security.JdaUser'"

JdaUser User = mmAppBase.Factory.CreateUserObject();

2. If I try to define my variable as the old mmUser, I get a compile-time error when I try to use my new member: "'OakLeaf.MM.Main.Security.mmUser' does not contain a definition for 'InitVecField'"

mmUser User = mmAppBase.Factory.CreateUserObject();	
Console.WriteLine(User.InitVecField);

If I comment out the Console.WriteLine() line above, it will compile and I can step through the code and watch it actually create a JdaUser object. Does anyone know how I can get the compiler to realize that the JdaUser object will be created so my InitVecField member should be available to me???
