This question is to seek out good examples of Hungarian Notation, so we can bring together a collection of these.
Edit: I agree that Hungarian for types isn't that necessary, I'm hoping for more specific examples where it increases readability and maintainability, like Joel gives in his article (as per my answer).
Do not use language specific prefixes.
We use:
n: Number p: Percentage 1=100% (for interest rates etc) c: Currency s: String d: date e: enumeration o: object (Customer oCustomer=new Customer();) ...
We use the same system for all languages:
SQL C C# Javascript VB6 VB.net ...
It is a life saver.
I only ever use p for a pointer, and that's it. And that's only if I'm in C++. In C# I don't use any hungarian notation. e.g.
MyClass myClass;
MyClass* pMyClass;
That's all :)
Edit: Oh, I just realised that's a lie. I use "m_" for member variables too. e.g.
class
{
private:
bool m_myVar;
}
