COM is a great thing that on Windows. there is a COM library with Phobos under the MIT licence:

the tlbimpd tool can generate a source module from a COM type library. see:

add COM support to Tango, only things to do is modify three module:,, for use with Tango

I'm new to D and Tango, would you please give me a hand ?

If it is a question of porting Phobos code to Tango, feel free to use these forums (or even this thread) or the IRC channel #d.tango on freenode to ask about details.

I assume you don't ask for COM support in Tango itself (COM's Windows only (at least in practice) nature makes it an unlikely thing to do in any case).

Is it a possibility that add COM support in Tango itself ? I use COM with Phobos and Juno before, but I really like Tango, want to switch to Tango now.

I am in no way familiar with COM, so I wouldn't know what would be required to add such support to Tango. Is it just a question of adding the correct ported headers? If so please add a wishlist ticket :)

To add COM support to Tango, Just wrap some Windows api.

The Juno's tlbimpd tool can generate correct D type COM headers automatically.

Would the tlbimpd tool need to be in Tango also? Or can it reside elsewhere?

Also, specifically which Win32 API's need to be wrapped?

The best thing is tlbimpd tool to be in Tango also, if not, The Juno's author John maintain the tlbimpd tool now:

How easy control COM object by use Juno with Phobos, I think Tango can do it better:
Example, run command line on Windows to get COM header(type library) of IE:

tlbimpd.exe SHDOCVW.DLL /propput:put /comments   

Generated shdocvw.d contains:

abstract class InternetExplorer {
  static GUID CLSID = 
    { 0x0002df01, 0x0000, 0x0000, 0xc0, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x46 };
  mixin CoInterfaces!(IWebBrowser2, IWebBrowserApp);

Just 2 line code to run a IE instance:

IWebBrowser2 ie = InternetExplorer.coCreate!(IWebBrowser2)(ExecutionContext.LocalServer); 

In, CoInterfaces? wrapped Windows api CoCreateInstance?. More details, see:

Oh, it's John Chapman's code?

Heck, if John is interested in having this available within Tango, then yes ... we should definitely talk with John about how to do that :)

That's great!

I'm waiting for the good news!
