Jonas,
I already read what you post in the online help of IDL. My problem is to find
the same fonction in Visual Basic.
Do you know what it mean this sentense:
> Keyword HTONL: Set this keyword to perform host to network conversion,
> longwords.
Because for me it is pretty obscure. I'm not working on a network so, what is
this keyword for?!?!
Thanks for your answer,
Skiso
