Send a String over a Socket
See more Socket/SSL/TLS Examples
Demonstrates Socket.SendString, which encodes a string using StringCharset and sends the resulting bytes over the connected socket. No delimiter, terminator, or length prefix is added.
Background. Text send and receive operations encode and decode bytes using the
StringCharset property. For plain ASCII or UTF-8 protocols, setting StringCharset to utf-8 is a safe default.Chilkat PowerBuilder Downloads
