Hi all,

I have questions according to the usage of TWinSocketStream.
If I call the Write method two or more times successively, not all data 
is transfered (in my application). If I code a Sleep(50) between them, 
the transfer works. Why? What is a good value for the Sleep?

The Read method of TWinSocketStream can return a "-1"?
I have read different answers in this newgroup: 23 Dec 2004, answer to 
Niyazi Unugur: "Read never returns -1. ..."

6 Apr 2005, answer to Paul: " ... You are not taking into account that 
Read can return -1 if an error occurs."

In the german help there is a hint, that the WaitForData method should 
be called always, if a Read or Write method is called afterwards:
In my code, the WaitForData only works for the Read method...

What is a usual size for packets written or read via TWinSocketStream?
I have no idea and need a starting point.

Thanks in advance
	Guenter
