Hi,

I want to interactive with an OLE application with pywin32. The
problem is I get totally no idea how to find the object in OLEView and
how to figure out it's interface.

With pywin32's example, I even don't understand that in the below statement,

win32com.client.Dispatch('Excel.Application')

that where the name 'Excel.Application' comes from? In OLEView
(Microsoft's COM brower), I cannot find this name.


Could you give me any help? Thanks

It's a "programmatic identifier" a.k.a. "progid".

It identifies a COM class and it's used as a readable but more
name-collision-prone alternative to the 128-bit UUID.

You can find the programmatic identifiers in the Windows registry (use e.g.
regedit); often they're not documented.


Cheers,
