Just playing around and the output is ugly.... but trying to get the count of the historycount() prior to any display.

;=====================================================================================
oSession = CreateObject("Microsoft.Update.Session")
oSearcher = oSession.CreateUpdateSearcher()
oHistory = oSearcher.GetTotalHistoryCount()
results = oSearcher.QueryHistory(1,oHistory)
filter = "SQL Server"
ForEach r in results
If StrIndexNC(r.Title,filter,0,@FWDSCAN)
txt = r.Date:@LF:r.Title:@LF:r.Description:@LF:r.SupportUrl
Display(2,"Update Results:",txt)
Endif
Next
oHistory =0
oSearcher =0
oSession =0
Exit

I may be completely missing the point of your question but the GetTotalHistoryCount() "Getter" method returns an integer and not an object. If you run your script in the WinBatch Studio debugger, you will notice that the data type of your "oHistory" object is "VT i4" which is COM Automation speak for a 4 byte integer.

Yeah. Totally screwed the question up. Wanted to get the count of the filter, i.e. number of updates with "SQL Server". But, while on the subject, want to confirm:
oSearcher.QueryHistory(0,1) ; latest update
oSearcher.QueryHistory(oHistory-1,1) ; earliest update
MSFT doesn't bother to mention exactly what QueryHistory's startIndex parameter means so a little trial and error might be necessary.
