thanks ! - this is exactly what i meant; - works fine.

though i have some troubles with CreateProcess - how to tell that this
process is a console job; - because when i launch from my GUI- the STDOUT is
(probaly) my GUI - is there any way to retrieve the STDOUT from a newly
launched Createprocess ?
