Hi all,

I am using the winsock for Visual Basic 6.0. The program that
I am debugging, request about 367 lines of ASCII data from
a UNIX server. Each line ends with a linefeed character and
the data is terminated by a NULL (0). I am able to use 
windump to demonstrate that the PC (Client machine) receives
all the required data from the server. However, the client
VB program just seem to have problem getting all the server
data. I have noticed that a call to GetData returns more
than one TCP packet. The VB Program seems to able to get
all the data from the server if the last byte of the data
returned by GetData ends in a linefeed character. If 
there are more characters after the last linefeed from
GetData then the VB Progam just cannot retrieve the
reminding TCP packets even though windump indicates that
all the data has arrived. 

Is there something that I need to adjust? Is this a
problem with the receive buffer of winsock as supplied by
VB 6?

Thank you
