Hello David, >I have found it very difficult to create classes in VFP 5.0. I thibk that creating classes is MOST wonderful thing that I know ;) >My first difficulty is using protected methods and properties. I find myself unable to access these functions and properties from instantiations of the class. Is this correct behavior? Is this reaasonable behavior? I often find myself declaring PROTECTED members can be accessed only from methods of this class. You can't use them from outside. >properties and methods public, even when they should not be. In such a cases, create a method to SET/GET a value of these properties. >My second difficulty concerns using an array in a class. In my case, this array is a hash table to the data in the ComboBox. Since there may be multiple instances of the class, and since the hash table is specific to the particular instance, the class >should contain the array. What is an elegant way of hiding an array inside a class such that each instance of the class has its own distinct instance of the array. Just create a property that is array actually.
