True, the constructor doesn't really add anything here.
To be honest, the combination of enumeration and runtime
variables in the Java code seems like a rubbish design, but
perhaps there's a good reason for it that I'm not aware of.
Maybe they extended enum to get over the lack of structs.
Looking at the spec for java enums it appears that you can return
an enumeration or the associated string using the original code.

foreach (ref m; mda) m.data.length = y;
or even this:

dgui - Button continually repainting
Hi.
I've created a graphic button as per this example on the dgui
website:
import dgui.all;
class MyForm: Form
{
this()
{
text = An Exception was thrown...;
size = Size(130, 100);
// Or use `Bitmap.fromFile`:
auto img = new Bitmap(90, 15, SystemColors.yellow);
auto pen = SystemPens.blackPen;
with(new Button())
{
bounds = Rect(10, 10, 100, 25);
parent = this;
paint.attach((s, e)
{
e.canvas.drawImage(img, 5, 5);
e.canvas.drawLine(pen, 5, 10, 95, 10);
e.canvas.drawLine(pen, 10, 5, 10, 20);
});
}
}
}
int main()
{
return Application.run(new MyForm());
}
and added a writeln(paint) in the paint.attach to show when the
button is repainting. When the form with the button is visible
the button is being continually repainted. Is this a 'feature' of
dgui or is there a flag to set to only re-paint when the button
is invalidated?

On Windows with scripting language, this is often done through COM automation: the IDispatch interface. With regular C functions, you really just have to know the prototypes ahead of time... it won't be fully dynamic, you load the library at run time but know how to use it at compile time.

Re: Overflow-safe use of unsigned integral types
On Sunday, 10 November 2013 at 12:05:45 UTC, Joseph Rushton
Wakeling wrote:
One of the challenges when working with unsigned types is that
automatic wraparound and implicit conversion can combine to
unpleasant effect.
Consider e.g.:
void foo(ulong n)
{
writeln(n);

void main()
{
foo(-3);
}
... which will output: 18446744073709551613 (or, ulong.max + 1

Is there a recommended way to handle this kind of potential
wraparound where it is absolutely unacceptable? I've
considered the following trick:
void bar(T : ulong)(T n)
{
static if (isSigned!T)
{
enforce(n = 0);// or assert, depending on your
priorities
}
writeln(n);
}
... but it would be nice if there was some kind of syntax sugar
in place that would avoid such a verbose solution.
I know that there have been requests for runtime overflow
detection that is on by default (bearophile?), but it could be
good to have some simple way to indicate really, no overflow
even where by default it's not provided.
(Motivation: suppose that you have some kind of function that
takes a size_t and uses that to determine an allocation. If a
negative number gets passed by accident, the function will thus
try to allocate 2^64 - n elements, and your computer will have
a very happy time...:-)
When writing software for embedded micros you can always check an
overflow flag - is the no such mechanism on PC software?

Pagesize
Is there an optimum size for pagesize? What does the pagesize refer to? I built DWT-Win and had to increase the pagesize to 4096 before it would build successfully. I have just built Tango 0.99.8 with the same pagesize settings and I got a warning that the pagesize was 512. I reduced it to 512 and that built ok. Regards, mike.

I want to use LPT to control a machine. Mike James Wrote: Zarathustra Wrote: Have you got any idea how to manipulate LPT port in Windows XP with D? Hi, Try the dlportio driver. I've used it in the past with XP - PIC programmers, etc. :-) Regards, mike. I've never used WinIO but you can get dlportio from http://www.driverlinx.com/DownLoad/DlPortIO.htm Regards, mike.

expected array behaviour
I have a function that uses 2 array strings defined similar to this... const char[] array1 = ABCDEFGHIJKLMNOPQRSTUVWXYZ; char[] array2 = ABCDEFGHIJKLMNOPQRSTUVWXYZ; If I make a change to a char in array1 it also changes the same in array2. But if I define the arrays as follows... const char[26] array1 = ABCDEFGHIJKLMNOPQRSTUVWXYZ; char[26] array2 = ABCDEFGHIJKLMNOPQRSTUVWXYZ; It doesn't occur. Is this expected behaviour? Regards, -=mike=-

Forgot to mention - Windows XP. Regards, -=mike=-
