Hi Chuck,

I am checking docs.
Aha, I was not correct.
We have next constructors:

    VULLong(inName as String)
    VULLong(inName as String, inFlags as integer)

This means that above code must be changed as:


    fldComposite = new vULLong( "Composite", kV_Indexed + kv_Unique )
    fldComposite.SetMethod( "(Component_ptr << 16) + Container_ptr" )


You do not touch isMethod property.
It is READ ONLY.
It will become TRUE after cal SetMethod().

Also, it seems you do not look into V4RBReference.pdf.
This is only important PDF for V4RB developers.
