A more natural boost::bind alternative?
Don't get me wrong: Boost's bind() is great. But I do hate to write&read code with it, and I've given up hope my coworkers will ever grok/use it. I end up with code like this: btn.clicked.connect(bind(&BetBar::placeBet, this, bet_id)); animator.eachFrame.connect(bind(&Widget::move, buttons[bet_id])); Which, while logical, is very fa...
OCaml syntax for passing in custom objects as parameters
I'm trying to get a grip on the OCaml language syntax and am having some trouble with applying some OOP structures. My goal with the below code is to have a class bar that inherits from a virtual class foo. The virtual class contains three virtual methods that I hope to take an instance of a "player" object as a parameter. When I compile...

Begin...End blocks in SQL Server: Is this code right?
I just want to verify that I'm not missing something here... so bear with me. I'm rewriting a lot of old stored procedures and keep seeing IF statements formatted similar to this: begin if @someParameter <> 'ThisType' set @someCode = right(cast(@pYear as varchar(6)),2) + 'THIS' end So the Begin...End block just wraps (but doe...
Why must delegation to a different constructor happen first in a Java constructor?
In a constructor in Java, if you want to call another constructor (or a super constructor), it has to be the first line in the constructor. I assume this is because you shouldn't be allowed to modify any instance variables before the other constructor runs. But why can't you have statements before the constructor delegation, in order t...
Absence of property syntax in Java
C# has syntax for declaring and using properties. For example, one can declare a simple property, like this: public int Size { get; set; } One can also put a bit of logic into the property, like this: public string SizeHex { get { return String.Format("{0:X}", Size); } set { Size = int.Parse(value,...
embedding one kind of syntax inside another: is it kludge or clever?
Background: Recently while looking at a "structured text editor" I noticed they used a trick to change python/perl/c++/java et al. into a "structured" outline by sneaking XML into the comments of the respective languages. I remembered seeing this trick inside a windows bat file once as well. The REM statements of the bat file were used ...

In c++ making a function that always runs when any other function of a class is called
C++ has so much stuff that I don't know. Is there any way to create a function within a class, that will always be called whenever any other function of that class is called? (like making the function attach itself to the first execution path of a function) I know this is tricky but I'm curious. ...

What does a "CALLBACK" declaration in C do?
I was looking through some code from the SDL library and came across a function declared like this: LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) Now, I'm a Delphi coder.

Delphi: how to automatically remove unused vars ("Variable 'x' is declared but never used" hint)
Is there any tool (preferably freeware) that can analyze Pascal/Delphi syntax and automatically remove unused vars? In my case, I'm working with a very large Delphi code base, and the compiler hints report over one thousand cases of "Variable 'x' is declared but never used". I would take hours to remove them by hand, and I might make e...
