COM type library importer
I've written an experimental tool that creates a D import module from a 
COM type library.

It should save you from having to convert C headers for COM programming.

Command line options that control the generated source code include:
	/comments - adds type library's helpstrings as comments
	/noenums - omits enum names
	/tabs - uses tabs to indent instead of spaces
	/indent - 10 or fewer indents
	/propget and /propput - prefixes for COM property accessors
	/module - the name of the generated module

Try it out (at your own risk - this is, as I've said, experimental).

Whooohooo!

Many thanks.  I'll test it out and let you know how it goes.

this is great! 
but seems i am not smart enough to use it properly. i ran the program on
msado15.dll and added the missing enums.

when i try to use the following

_Connection oDatabase = Connection.create!(_Connection);

oDatabase will always be null. the same is for 

_Recordset oRecords = Recordset.create!(_Recordset);


could you give me some pointers?

thanx

I'll be uploading a bug-fixed version shortly which correctly generates 
enums.

Ensure you're initializing COM with CoInitialize. I usually do so in a 
static module ctor, like this:

	module main;

	import com;

	static this() {
		CoInitialize(null);
	}

	static ~this() {
		CoUninitialize();
	}

Hope that helps.

A suggestion: wouldn't it be better to have those in your com module? I mean, 
they're going to be needed anyway, so why not make things easier for users?

I agree. I'll make the change.

Re: COM type library importer
TLibD v0.15 is now ready. I've been concentrating on making it generate 
code that can be compiled without errors or having to hand-edit it.

The zip file contains the source code if you're wondering how it's done. 
It's not too pretty, though.
