声明:本文只在于技术讨论,希望不要被一些无聊的人来做无聊的事......
一.用到的主要技术
1.多线程技术
2.动态定位API
3.非DLL的远线程代码注入
二.本程序写在控制台下,主要功能都在main_pas单元文件中实现。工程文件main_pr只调用一个MianThread函数就OK!程序我加上了详细的注释.....大家可以慢慢看...
三.工程文件main_pr如下...
program main_pr;
//{$APPTYPE CONSOLE} //注释掉这个句,免得看见那难看的DOS黑框^_^
uses
windows,
main_pas in 'main_pas.pas';
begin
MainThread();
{ TODO -oUser -cConsole Main : Insert code here }
end.
四.单元文件main_pas如下....
unit main_pas;
interface
uses
windows ,SysUtils,psapi;
