Hi,
I tried what you proposed but did not work.
I created a class as follows:
class TMyServerSocket : public TServerSocket
{
public:
__fastcall virtual TMyServerSocket (Classes::TComponent* AOwner)
: TServerSocket (AOwner)
{
}
void SetLocalAddress ( AnsiString address )
{
Address = address;
};
};
Then I connected as follows:
TServerSocket * ServerSocket = new TMyServerSocket(NULL);
((TMyServerSocket*)ServerSocket)->SetLocalAddress ( ip );
ServerSocket->Port = port;
ServerSocket->Active = true;
But when I print the Socket->LocalAddress property,
it writes 0.0.0.0 and still works with multiple IP.
