Public Function UpdateCounter (ByRef pCurUpdate As UInteger, ByRef pgrfChanges As UInteger) As Integer

Parameters

pCurUpdate: UInt32

[out] Returns the current update counter.

pgrfChanges: UInt32

[out] Returns a combination of values from the _VSTREEITEMCHANGESMASK enumeration specifying what kind of changes have been made since the last time this method was called.

Returns

Int32

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.
