Trying to create a windows .lnk file, the typical way is to use IShellLink... but can;t find it under sys.win32 heres some c++ code i've used in the past...

void CreateShortcut(LPWSTR root, LPWSTR link)
{
	HRESULT hres;
	IShellLink *psl = NULL;
	IPersistFile *pPf = NULL;

	if (fileExists(link))
		return;

	try{
		hres = CoInitialize(NULL);
		hres = CoCreateInstance(CLSID_ShellLink, NULL, CLSCTX_INPROC_SERVER, IID_IShellLink, (LPVOID*)&psl);

		SetErrorMode(SEM_FAILCRITICALERRORS);
		try{
			hres = psl->SetPath(root);
		}catch(int e){}
		
		hres = psl->QueryInterface(IID_IPersistFile, (LPVOID*)&pPf);
		hres = pPf->Save(link, TRUE);
	}catch(int e) {}
	refreshDesktop();
}

I know nothing about COM but I thought it would be educational to dig into it a bit.

It looks like Phobos has some COM bindings in std/c/windows/com.d.

Prototypes for CoCreateInstance? and the like are found there.

I don't see any equivalent in Tango at the moment, but of course Tangobos includes it, so you can use it from there.

I can't seem to find many COM usage examples, but maybe the COM client-server example in dmd/samples/d (of compiler installation dir) may be of help. In particular dclient.d is calling a simple COM interface that is set up in chello.d.

Tango does indeed have fairly weak support for COM programming, but the DWin project at dsource should have most relevant bindings presented in a Tango compatible manner.

Bjoern on the NG recommended looking at this for D + COM info:

And John Reimer recommended the tango friendly:
