Learning how to make custom classes and drag out an “Object” from the Toolbox on the left hand side.
NOTE : To see an “Object” you must set the tools list to show all controls. Like this – http://i50.tinypic.com/153tx6v.png
Then in it’s properties panel you must set it’s “Super” to “cMyCalculator”, basically meaning that it will act as a new object of the cMyCalculator type. Inheriting all of it’s methods and anything else it posses.
Unfortunately the website I hosted my code on has vanished. However, my videos show all the source code. Watch them and pause to see the code.
