मैंने टीएलबी से आईडीएल निकालने के लिए यह त्वरित और गंदा हैक लिखा है। यह वही उपयोग करता है (मेरे सर्वोत्तम ज्ञान के लिए) COM ऑब्जेक्ट जो OLEVIEW.EXE उपयोग करता है।
/*
Extract the IDL from a tlb file and print it to stdout.
The tlb file is analysed by a COM object of type CLSID_ITypeLibViewer and
the extracted IDL is shown in a window created by the same object.
This program extracts the IDL from that window.
Usually Microsoft's OLEViewer (a.k.a. OLE/COM Object Viewer) registers a
COM object of that CLSID_ITypeLibViewer (for example inside a dll called
IViewers.Dll), I've tested it with:
IVIEWERS.DLL "OLE/COM Object Interface Viewer" Version 6.0.6000.16384
