VB有两种启动方式:Sub Main()和Form
第一种方式,只允许Sub类型的Main,而不允许Function,所以无法设置返回值;
第二种方式...根本就没地方设置返回值啦...2. VB6不支持控制台程序,不过也许调一些输出到控制台的API可以实现...没试过~
(不过VB .NET已经完全支持Console Application了~)
2.VB的程序可以往一个Console中输出,但这个Console是程序自身打开的进程才行,对于在当前的一个Console中输出目前还不知道怎么处理。
我用C倒做过。

这个也能写出来,我要仔细看看
调用 Win32API 里面的几个控制台函数也可以。
