Hi,
Forget my prev post. I have found my mistake.
I have declared a timeout variable
AppNetTimeout
but I have used
AppNetTimeOut
(see the capitalized oO)
Both variables were correctly declared (by default) and the one I
initialized was NOT the one I used but the one I used was initialized with 0
so the netlib-call returned immediately with errTimeout :-)
It is always the little things that make live soooo difficult.
Thanks anyway
Ole
