The
Windows Application Derived Classes
The primary aim of the derived classes is to extend the abstract base classes
by implementing the abstract event handler methods. In addition they can contain
any auxiliary methods called by the event handlers. In practice, the derived
classes contain any application specific logic that we want to keep out of
the abstract classes which thus remain fully generic.
Each derived class inherits from the corresponding abstract base class as follows:
Inherits libCtlArray.clsTxtArray
Each derived class contains one or two constructors, depending on which container
controls are used in the client application.
e) Constructor # 1 caters for controls located on Windows
Forms
f)
Constructor
# 2 caters for controls located on Windows User Control
In addition, the constructors contain three parameters to identify the array
items
g) Control Prefix string [eg. strText]
h)
Array identifier string [eg. strArr]
The derived class constructor instantiates the corresponding base class which,
as we saw in the preceding section, populates the arrays.
