I'm just reading Andreis book "Modern C++ Design" and try to translate a
few examples to D 2. My most recent test looks as follows:
import std.stdio;
struct Type2Type(T){
typedef T OriginalType;
}
class foo(T,R...) : foo!(R) {
public void print(){
super.print();
Oh I've just realized I was being a little silly here. I don't need
ref for pointers. Essentially I was looking to make this:
auto ref unqual(T)(ref T value)
{
return cast(Unqual!T)value;
}
do this:
char* unqual(const char* value)
{
return cast(char*)value;
}
Except to make it work for an
Well I've tried it with a COM object and it seems to work. So I'll
definitely use this technique now. I do wish whitehole gave me the
option to throw a custom error message.

You'll need a couple of things:
Link with the user32.dll import library, which is located in
DMD\dmd2\windows\lib\user32.lib.
Either pass it to DMD during compilation or more simply just can add a
pragma(lib) in your source file like so:
pragma(lib, "user32.lib");
And you need the function protot
I have a similar problem. :)
I'd like to catch a call to a COM object to check if it was properly
initialized first.
Here's one way to do it with regular classes:

{

unqual(t);
}
auto ref unqual(T)(ref T value)

}
I've attempted to create myself an unqual function which could for example do a
cast from const char* to char*. The above won't work though:

So my research into making a nice friendly to use COM interface wrapper
for D has had a few odd turns and I am wondering if there is an answer
to making the implementation nicer.
I discovered the 'alias foo this' syntax to let structs nearly
seamlessly impersonate a member variable. This has
import std.algorithm;
struct Foo
{
int bar(string) { return 1; }
void run()
{
auto result = map!(bar)(["test"]);
}
}

Yeah.
Hello,
I'm not familiar with DLLs, I would like to know how can I call a
function in User32.dll ? (specifically, RegisterWindowMessage)
Thank you for any help!

I'm trying to get a D2 project to build on Ubuntu through Code::Blocks.
Unfortunately, Code::Blocks doesn't allow the simple one-step compilation that
is default with dmd, so it does compiling and linking in two separate steps.
Unfortunately, this is causing some linker errors, the main one being:

Does your library take into account that there's no year 0?
Actually, for ISO 8601, which the library follows, there _is_ a year 0.
