I implemented an IDropTarget object, So my object will be
able to handle drop of files. The user drags files into
that object.

As you all probably know, The ::Drop method of that object
gets a pointer to IDataObject as parameter.

I'm looking for a code that gets the names of the files that
were dragged into my IDropTarget object, from that horrible
"IDropTarget" object.

Here's a sample drop method to help you out...

STDMETHODIMP SampleType::Drop (IDataObject *pDataObj,
DWORD grfKeyState, POINTL pt, DWORD *pdwEffect)
{
HRESULT hres = E_FAIL;
FORMATETC fmte = {CF_HDROP, NULL, DVASPECT_CONTENT, -1, TYMED_HGLOBAL};
STGMEDIUM medium;

if (pDataObj && SUCCEEDED (pDataObj->GetData (&fmte, &medium)))
{
char szFileDropped [MAX_PATH];

DragQueryFile ((HDROP)medium.hGlobal, 0, szFileDropped,
sizeof (szFileDropped));
TRACE ("SampleType::Drop(%s,%s)", this->szFileName, szFileDropped);
hres = S_OK;

if (medium.pUnkForRelease)
medium.pUnkForRelease->Release ();
else
GlobalFree (medium.hGlobal);
}

return hres;
}

Cheers,

Raymond.
