I am not able to use the component TWSocketServer with POS terminals (do
not have access to sources of client developed in C), the error occurs
after the connection "OverbyteIcsWSocketS"
TCustomWSocketServer.TriggerSessionAvailable procedure in the procedure
(Error: Word);
{Ok, the client is still there, with the connection process}
if (FMaxClients> 0) and (FMaxClients <ClientCount) then begin
{Sorry, toomuch clients}
Client.Banner: = FBannerTooBusy;
Client.StartConnection;
Client.Close;
end
else
Client.StartConnection / / <------------- ERROR HERE
The connection terminal is lost!
I need to do is receive multiple simultaneous connections to these
terminals make query on a sql server database and returns the contents, was
using indy and would like to migrate to ICS plus'm having these problems!
Thank you again!
