Receive a Bounded String from a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveStringMaxN, which receives and decodes text like ReceiveString but reads at most a given number of input bytes.

llSuccess = .F.

loSocket = createobject("CkSocket")

//  Connect to the server using TLS.  The 3rd argument enables the TLS handshake after the TCP
//  connection succeeds; the 4th is the maximum time to wait, in milliseconds.
llBTls = .T.
lnMaxWaitMs = 5000
llSuccess = loSocket.Connect("example.com",5000,llBTls,lnMaxWaitMs)
if (llSuccess = .F.) then
    ? loSocket.LastErrorText
    release loSocket
    return
endif

//  StringCharset controls the character encoding used when sending and receiving text.
loSocket.StringCharset = "utf-8"
//  Send a request using a simple application-defined text protocol in which each message ends with a
//  CRLF.
lcCommand = "STATUS" + Chr(13) + Chr(10)
llSuccess = loSocket.SendString(lcCommand)
if (llSuccess = .F.) then
    ? loSocket.LastErrorText
    release loSocket
    return
endif

//  Receive and decode text like ReceiveString, but read at most the given number of input bytes.
//  The limit is measured in bytes, not Unicode characters.
