Hi Abhishek,

For understanding these interfaces, MSDN is your friend. You can check MSDN's documentation for details on the IShellFolder interface. [1]

In general, these interfaces are known as COM interfaces [2]. The QueryInterface function comes from IUnknown which IShellFolder inherits from. [3]

Why don't you explore these files more and search for copy-paste functionality? Use the search box on the top right. For example, I found references to platform specific drag and drop code. [4]

Hope this helps!

Cheers,
Aaryaman

Again, please _bottom post_ and keep wine-devel in CC.

You should ideally have submitted a patch by the time you've sent in
your GSOC application. Your patch MUST be accepted by March 27 16:00
UTC (student application deadline). I would HIGHLY recommend against
waiting until the last minute.
