Thank's a lot for your help Hermam. All is working fine, but some strange feature appears, when I create the first process, I need about .3 - .4 second to perform it, and if I create it the second or more time, it just need .02 - .05 to do it !!!

The best way, is to create the first one even with nothing, and if the objetct stay in memory long enought to a second one will process in 0.02 to 0.05 seconds !!! It's exceptionnal !!!

Regards,
Roman
