Hi,

I would like to perform some work whenever a document window is closed in
the IDE. Currently I've implemented IVsRunningDocTableEvents3, and inside
OnBeforeLastDocumentUnlock(), I do the following:

if (dwRDTLockType == (uint) _VSRDTFLAGS.RDT_EditLock && dwEditLocksRemaining
< 1)
{
// do some work via the docCookie parameter
}

This seems to be working well enough, but I wanted to know if there is a
better/safer way to handle these user events. I had originally thought to do
this work inside OnAfterDocumentWindowHide(), but I found in practice that
although this gets called at the appropriate times, its docCookie parameter
always seems to be 0, which is invalid. Hence I can't determine what file
was modified.

So, what's the best way to trap document closing events?

Thanks.
