Hi, I'm trying to access the Windows Registry, so I'm using RegOpenKeyA(). The thing is that this function receives an HKEY, which is a HANDLE, which is an int. But I want to open HKEY_LOCAL_MACHINE, which value is 0x80000002, that is an uint. I tried to declare RegOpenKeyA() in windows.d to receive an uint, but the linker complained (I think that's pretty obvious). What should I do? What I'm trying to do is to get the processor's description. I know I can do it calling the Win32 API, but if I use the registry I don't need to parse the information I get. Besides, later I need to get the list of installed programs, which is also in the registry. So it seems like I don't have a choice. Any ideas? ------------------------- Carlos Santander --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com).

the windows.d i have does it like this:
enum : HKEY
{
//stuff
HKEY_LOCAL_MACHINE=((HKEY)0x80000002)
//stuff
}
i bet this would work too though:
const HKEY HKEY_LOCAL_MACHINE=cast(HKEY)0x80000002;

Well, doesn't work either. I still get: Error 42: Symbol Undefined

Of course!!!!!!!!!!!!!!!!!!!!!!!!! I had no idea it needed
advapi32.lib....................
I'm gonna shoot myself!!!!!!!!!!!
(well, not so much)
also, for some reason, besides src\phobos\windows.d, I have a really old
Pavel's windows.d (more complete, though), and there's where I had all those
weird declarations.
my God!!!!!!!!!! how can a human being be sooooooooooooooo stupid?
By the way, dmd compiles (and links) my file just fine if I declare (since
it's not in Walter's windows.d) RegOpenKeyA as (void *,LPCSTR,PHKEY) or as
(int,LPCSTR,PHKEY). why? are void* and int the same? (I know they're not,
but still....)

ummm...Good question. They're both the same size. Maybe they just both show up as double words in the lib files rather than specific types? That doesn't seem right though. On a completely unrelated note. Why does Microsoft have to put reply and reply to group right next to eachother?

void * is the same size as int. Both 32-bits. You're kind of tunnelling through the type system, and it works because of the same size. To a processor, there is no difference between void* and int32 "Jon Allen" <jallen minotstateu.edu> wrote in message news:b60nlr$2jb$1 digitaldaemon.com...Of course!!!!!!!!!!!!!!!!!!!!!!!!!

Do you know whether exported finction in libs (or dll's for that matter) contain any type information besides just sizes? It seems like they should but it also seems like they don't.

They don't. While this can be an opportunity for errors, it does also present some nice opportunities. I've just been working with C# and talking to C DLL functions. By declaring the function signatures with differing, but known (by me!) to be benignly equivalent, types, I can avoid a whole load of tiresome casts throughout the C# class code. Of course, this is dangerous, but used judiciously it can be a nice thing.

The D calling convention has type information in the signatures so they can be differentiated, but the Windows calling convention has the stack size only, which is what the 12 at the end is indicating.
