/vmb, /vmg (Representation Method)

Select the method that the compiler uses to represent pointers to class members.

Use /vmb if you always define a class before you declare a pointer to a member of the class.

Use /vmg to declare a pointer to a member of a class before defining the class. This need can arise if you define members in two different classes that reference each other. For such mutually referencing classes, one class must be referenced before it is defined.

Syntax

/vmb  
/vmg

Remarks

You can also use pointers_to_members or Inheritance Keywords in your code to specify a pointer representation.
