[BEHZADTALA]

Hi,
i have written a program in VC++ that call Extranet.exe
with CreateProcess. i pass the needed parameters for
Extranet.exe program (Contivity VPN client with IPsec protocol)
and it is connected but i can not recieve the message from
Extranet.exe that give me the handle window of itself.
the command that i send with CreateProcess is like:
Extranet.exe -h handlewindow of my program -m message handle
-a name of connection
it's worked succesfull and i must give the callback
message but there is no message in queue.

could you help me what is the problem.
