                   TDatabase  *sin;
                    .
                    .
                   sin->Exclusive = false;
                   sin->HandleShared=false;
                   sin->KeepConnection=true;
                   sin->ReadOnly=false;
                   sin->DatabaseName="local";
                   sin->LoginPrompt=false;
                   sin->Params->Values["User_Name"] = "link";
                   sin->Params->Values["Password"] =  "clear";

Is your TDatabase pointer actually pointing to anything?

TDatabase *sin = new TDatabase;

sin->Exclusive = false;

etc.
