Thanks,

it works fine with excel saved on the disk.
I still falling into original problem,
when an excel report opened from WEB. The file saved in the "Temporary
Internet Files" and a name is changed from "report_XXXX.xls" to
"report_XXXX[1-N].xls". Excel raise a security warning concerning a
document referenced to an internet
space, either it treats a name as report_XXXX(1-N).xls.

Any ideas, how possible to get a "clean" workbook name ?

Thanks
