I have been using Excel automation for years. However, I could not find
a way to kill the Excel application when an error occurs.
Here is an example:
I have this cursor with an inventory list that contains 9000 rows and 10
columns, named curStock.
I save the cursor with:
local cExcel
cExcel = 'c:\temp\stock.xls'
select curStock
copy to (cExcel) type xl5
if upper(vartype(thisform.oExcel)) = "O"
thisform.oExcel.quit
thisform.oExcel = .f.
Else
thisform.AddProperty('oExcel')
EndIf
if upper(vartype(thisform.oExcel)) <> "O"
thisform.oExcel=createobject("Excel.Application")
else
thisform.oExcel=getobject(,"Excel.Application")
endif
Try
lOK = .t.
With thisform.oExcel
.workbooks.open("&cExcel")
endwith
Catch to oError
lOK = .f.
MessageBox(oError.message,16,'Excel caused an error',2000)
thisform.oExcel.quit
EndTry
if not lOK
quit
else
*** show the spreadsheet
endif
The property thisform.oExcel is trying to open the big Excel sheet
(stock.xls) but fails
Supposedly thisform.Excel.quit should kill the Excel instance.
However it still remains in memory. The task manager shows it is still
dangling in memory but is invisible.
How can I kill it?
BTW I use this approach instead of filling and formatting the sheet line
by line, because it takes about half an hour to show, due to the large
amount of records the cursor contains.
