hey everyone,
im trying to write a script as well as a program each of which can 
communicate with one another.  the script should be able to have access 
to the class in my c++ code.  just a simple class with a couple of 
variable and some accessors and modifiers for them.  i want to be able 
to create an object of that class type in the script and call the 
classes functions in order to manipulate the data.  at this point i can 
create an object in the script and it seems that i can modify the object 
through the set methods, but when i call the get method for that 
function it get an error saying it is expecting the class type as the 
return type(i assume thats what the error means.. "in 'getInt': wrong 
type - expected DummieClass")
for all of my set methods i return self.  for the get methods i return a 
VALUE object which should be holding the value of the class member i am 
working with.

********************************************************************
c++ code:

static VALUE _wrap_get_int(VALUE self)
{
    GET_MY_CLASS(self);  //a macro that returns an instance pointer of 
my class

    //this function call returns a VALUE after converting the c++ int
    return GetRubyInt(pDummie->getInt());
}

*********************************************************************
ruby script:

obj = SimpleExt::Dummie.new(12,3.4, "my String")
obj.setInt(100)
x = obj.getInt()

print x

***********************************************************************

it seems to be crashing out when it gets to the line x = obj.getInt(). 
can anyone tell me whats wrong with this, or am i going about this the 
wrong way?  im thinking that i may have to change my c++ code around, 
but i dont know.  if anyone could lend some adive i would appreciate it.
thanks
steveD
