In VB6 what is the difference between Property Set and Property Let?

Conventions for accessor methods (getters and setters) in C++
From my perspective as sitting with 4 million lines of C++ code (and that’s just one project) from a maintenance perspective I would say: It’s ok to not use getters/setters if members are immutable (i.e. const) or simple with no dependencies (like a point class with members X and Y). If member is private only … Read more
What are getters and setters for in ECMAScript 6 classes?
These setter and getter allow you to use the properties directly (without using the parenthesis) var emp = new Employee(“TruMan1”); if (emp.name) { // uses the get method in the background } emp.name = “New name”; // uses the setter in the background This is only to set and get the value of the property.
Python overriding getter without setter

WPF: XAML property declarations not being set via Setters?
The “CLR-wrappers” for dependency properties only get called when done through code. XAML depends on the name specified in the DependencyProperty.Register(…) call. So, instead of “extending” the logic of the setter for your dependency property like you did above, just put your custom logic in a PropertyChangedCallback function.
Stack overflow exception in C# setter
When you write a = value, you are calling the property setter again. In order to use non-automatic properties, you need to create a separate private backing field, like this: ConstraintSet a; public ConstraintSet A { get { return a; } set { a = value; } }
Monitor All JavaScript Object Properties (magic getters and setters)
Looking through the nowjs source code, I believe they do this by continuously monitoring the now object and pushing changes between client and server whenever they are detected. I admit I haven’t fully grokked their code yet, however. In a browser, this would be done with some fun setInterval hacks. EDIT: yes, that is indeed … Read more
Setter methods or constructors
You should use the constructor approach, when you want to create a new instance of the object, with the values already populated(a ready to use object with value populated). This way you need not explicitly call the setter methods for each field in the object to populate them. You set the value using a setter … Read more
Setters not run on Dependency Properties?
The WPF binding engine calls GetValue and SetValue directly (bypassing the property setters and getters). You need the property to be there so it can be supported in the XAML markup (and compile correctly).
