Remarks
COM Signature
From vsshell80.idl:
HRESULT IVsPreviewChangesList::UpdateCounter(
[out] ULONG *pCurUpdate,
[out] VSTREEITEMCHANGESMASK *pgrfChanges
);
This method updates the current change counter each time it is called and returns that counter. This method can also return what kind of changes were made.
C++: you can set the pCurUpdate and pgrfChanges parameters to NULL pointers to simply force an update of the counter.
