Send string with synapse

[xinyiman]

I'm creating a client server application with Lazarus and synapse. And I must say that almost everything works. I can only understand why using these two pieces of code to send and receive strings sometimes read string dirty data of previous sending and receiving. How can I clean the buffer before sending any string?

thanks

Code: [Select]

function TMyClient.GetString: string;
var
   buffer: String;
begin
     buffer:='';
     buffer := sock.RecvPacket(6000);
     //buffer:=sock.RecvString(6000);
     result:=buffer;
end;     

Code: [Select]

function TMyClient.SendString(str: string): boolean;
begin
     sock.SendString(str);
end;
