Contrôles ActiveX en VFP
Hi Jordan,

Right, but why don't you use TCP/IP between the cash register and the ECR server ? (Perhaps the cash register is not PC based ?)

Which VFP restrictions ?
>In reality this is the same MS Winsock control (with the same features, >possibilities and restrictions, which are well explained in MSDN Help and >articles), but wrapped.
You're talking about Listen function and the backlog (=5) parameter (which limit the usage of Ms Winsock OCX)
int listen(
SOCKET s,
int backlog
);
>We distribute it as a OCX. It works with Winsock2.0. You can use MSDN help
Fine, how could I test it ?
Sincerely,
Roman
