Lloyd, if the program you're writing is designed to be sold or distributed to the public then I'd highly recommend against doing anything that requires at least Vista. From what I've heard, the adoption rates of Vista and Win7 haven't been very good and about half of the Windows systems out there are still XP and pretty much holding there. A *lot* of Windows users are deliberately sticking with XP, and you'll be loosing a lot of people. Of course, if your software is only designed to be used internally by some company, or just for you own use, etc., then obviously it doesn't matter...
Stack traces when stack overflow
This crashes at runtime because of a stack overflow, without stack frame or
error message (DMD 2.053), no stack trace, or line number are shown:
int foo(int n) {
return n ? foo(n - 1) : 1;
}
void main() {
foo(100_000);
}
If you aren't running a debugger then receiving a nude crash is not so nice,
because in a larger program there are many functions that may be the cause of
such stack overflow. So is it possible to add some stack protection code (in
non-release mode only, if necessary) to receive a stack trace in this case?

It's not in kernel32.lib distributed with DMD. You would have to create an OMF import lib by calling implib /system kernel32.dll (your own kernel32.dll) if you're actually using Vista or a newer OS and then linking with that.

Thanks a lot,
I solved it by using
pGraphics.clear();
pGraphics = null;
// pGraphics.rehash();
I thought this'll solve my problem, but it doesn't... I've to fill my
AA every 500 ms with around 250 values (in principle much less than
10_000_000_000). When I start my application (in this context, my
game), it works as needed (around 2000 fps/s) but after some seconds,
the fps-rate drops down to 1/s and back to normal (and again, and
again...). When I remove the command to clear the array, it works
without dropping down to 1 fps. I this case I can't update my screen
as needed. I also tried to delete the class instance which contains
the array and create an new but it's the same as before (it drops
down to 1 fps). Is there anything I forgot to consider?

Typically, windows functions come in two varieties, the A and the W
version. This is hidden by a macro in C, so all you ever call is
GetUserDefaultLocaleName (and that's how it is in the docs even). But in
D, which does not have a pre-processor, you must add the A (ascii) or W
(wide) to the function name. Try:
extern(Windows)
{
int GetUserDefaultLocaleNameW(LPWSTR lpLocaleName, int cchLocaleName);
}

I found half the answer to question 1 (internationalization)
I still dunno how to get the local language (I guess I'll have to find the

but I found how to do the resources!! (using mixins)
what do you think?

mixin(import("lang.fr.txt"));
