tlookup_name.cpp

VC++编写的类似Sniffer的网络数据包监听程序

//   Important: Methods and properties of objects in VCL can only be
//   used in a method called using Synchronize, for example:
//
//      Synchronize(UpdateCaption);
//
//   where UpdateCaption could look like:
//
//      void __fastcall Unit1::UpdateCaption()
//      {
//        Form1->Caption = "Updated in a thread";
//      }
