I've been spenting a good number of hours reading this, trying that, and I've finally gotten the small test program to complie and link, but gI et an "Error: Access Violation" error when I run it.

This is the Test Class in WinDLL.d:

# export class Test
# {
#    public:
#    export this()
#    {
#       printf("Test.this()\n");
#    }
#
#    export ~this()
#    {
#       printf("Test.~this()\n");
#    }
#
#    export void hello()
#    {
#       printf("Test.hello()\n");
#    }
# }

Here's the .DEF file I used:

# LIBRARY      WinDLL
# DESCRIPTION  'Windows example DLL written in D'
#
# EXETYPE      NT
# SUBSYSTEM    WINDOWS
# CODE         PRELOAD DISCARDABLE
# DATA         PRELOAD SINGLE
#
#EXPORTS       _Class_6WinDLL4Test

The _Class_6WinDLL4Test I hand wrote in after dmd and the linker didn't place this entry in the DLL...not sure if I'm suppose to do it this way. But all three of methods in the Class all showed up, so the "export" next to them seem to work just fine.

Then I compiled the WinDLL.dll with the following line:
dmd windll.d windll.def

After downloading ftp://ftp.digitalmars.com/bup.zip, and extracting implib.exe into "dmd\bin" directory.

I then created the WinDLL.lib with the following line: implib /system windll.lib windll.dll

Used the following loader.d code below:

# import std.loader;
# import std.stdio;
#
# import WinDLL;
#
# int main ( char[][] args )
# {
#    char[] sLibName = r"C:\dmd\WinDLL.dll";
#
#    auto ExeModule xmod = new ExeModule( r"C:\dmd\WinDLL.dll" );
#
#    writefln("\"%s\" is loaded", r"C:\dmd\WinDLL.dll");
#
#    Test oTest = new Test;
#
#    return 0;
#
# } // end main()

And a final compile loader.exe with the following line:
dmd loader.d windll.d windll.lib

I sure hope someone can tell me what I'm missing, since I've mainly created "C" EXE and .DLL in the past, I've never had any Classes to export into DLL before...now it would be great if I could learn how it is done, by a Class Pro! ;)

Thxs for any help, or pointers in advance!

I think the standard DLL format (or whatever it's called) doesn't allow
that.
I know that currently there's no way to do that with DMD.
