What's New in Visual Basic 14: Parameterless Constructors in Structures
While everyone using the .NET Framework creates Classes, not many developers create Structures. For those of you who are creating Structures, Visual Basic 14 has some good news for you: You can now give your structure a constructor that doesn't accept parameters (a default constructor). Formerly any constructor you added to a Structure had to accept at least one parameter.
Here's an example of a Structure with a default parameter:
Private ErrorCount As Integer
ErrorCount = -1
If you want to have your default constructor actually execute, however, you must use the New keyword. This code will call the constructor and set ErrorCount to -1:
Dim pd As New ProcessData
This code will not:
Dim pd As ProcessData
and it will still run. Nifty, right?
