D - [win32]How use a dll?

Hello!

I'm new to 'D' .. sorry for this stupid question.
1. I create a dll with a class (proceeding: D for Win32)
class test
{
export
{
this()
{
}
~this()
{
}
void doIt()
{
printf("Im the dll\n");
}
}
}

2. compile: dmd test.d test.def
3. I have: test.dll, test.map, test.obj

In c++ i have a '*.lib' file for the dll. How can i use this dll in a other
D - exe (program)?

Thanks in advance.
Bye
Uwe

My english is not the best. :-)

I'm not sure about this but it might be the same problem I
had (I'm not a windows guy).

You have to use the implib utility from 
http://www.digitalmars.com/download/freecompiler.html
as I remember that will create a .lib.

Thanks! 
My proceeding:
in the file 'test.d':

class test
{
export
{
this()
{
}

~this()
{
}

void doIt()
{
printf("test.doIt()\n");
}

}
}
and the other stuff for win-dll creation

compile: dmd test.d test.def
implib : implib /s test.lib test.dll

In the file 'testdll.d':

import test;

void myfunc()
{
test xx = new test;
xx.doIt();
}

compile: dmd testdll.d test.lib

dlltest.obj(dlltest)

:-(

Any ideas?
Thanks in advance.

Ah, I think I see your problem now. Put the export
in front of the class declaration:
export class test {
etc.

This will export both your class and the public methods of
your class. Note that when you use the export keyword,
you don't need to use a .def file.
