Remarks
The string
that the lpsz parameter receives has a format like the following sample:
[c200e360-38c5-11ce-ae62-08002b2b79ef]
where the
successive fields break the GUID into the form DWORD-WORD-WORD-WORD-WORD.DWORD
covering the 128-bit GUID. The string includes enclosing braces, which are an
OLE convention.
