Is there any program that can take a D file and essentially make 
an H file for other programs to import for dll work?

I want to create the DLL's in D rather than C++ and would like to 
generate the H file from the D file.

Also, when I try to load a dll generated by matlab(the target) it 
says that it is an invalid dll.

Maybe you can get a simple dll to work?

import core.sys.windows.windows;
import core.sys.windows.dll;

export extern(C) int foo()
{
	return 42;
}

mixin SimpleDllMain;


and for the .h file

__declspec(dllimport) int foo();

then in matlab

unloadlibrary test
loadlibrary test
calllib('test', 'foo')

seems to work out.

To auto generate, simply set the options to generate the 
interface file then use something like sed

sed -i "/^\(export\)/!d" file
sed -i -e "s/export extern (C)/__declspec(dllimport)/g" file

and this will extract the exports and fix up things for matlab to 
use.
