method SendStr(Str:String): integer;
SendStr sends the data provided in Str to the socket connected with this TWSocket. For UDP connections no explicit connection exists, for TCP connections a connection must be established before SendStr may be used.
The following example establishes a TCP client connection to another socket at 192.168.0.1:1234 and sends the string Hello World to it. Afterwards the connection is closed and the socket is freed.
var MySocket:TWSocket; s :String; MySocket:=TWSocket.Create(nil); MySocket.Proto:='tcp'; MySocket.Addr:='192.168.0.1'; MySocket.Port:='1234'; MySocket.Connect; s:='Hello World'; MySocket.SendStr(s); MySocket.Close; MySocket.Free;
- for sending strings in line mode you must remember to manually attach the defined delimiter to the end of your string
