一起来谈一下vb.net里的多线程吧
看我的程序

dim myform as new form1,i as integer
myform1.show


for i=0 to 100000
next


大家看这里，form1是我写的一个窗体，大概的内容就是，在窗体load时，运行
一个多线程的程序来实现显示现在时间，但是现在有些问题，就是必须得等fro循环结束
后，form1的时间才开始显示，也就是说,这个多线程没有起做用,
这个程序我的目地就是，在myform1窗体显示完后，该窗体就运态的显示时间，这时，也
同时执行for循环。

注：在运行for循环时,我用任务管理器看了一下,cpu是100%,

会的就贴上贴子来，

将你需要的方法加入一个Delegate，然后再For之前使用BeginInvoke调用委托，就会新建一个线程执行委托了。

注意线程安全问题哦。

能好好说一下吗，最好在我的程序上改动一下，谢谢你了，我很急的!

你这哪是多线程啊！只有一个线程啊！执行循环时系统都会挂了。应该创建一个新线程，将循环放在新线程里执行，你的程序就不会挂了。具体看MSDN，很多的。

msdn我看不太好，这个.net里的msdn很乱，我现在还不知道怎么开，能不能在我程序的基础上给我改一下，叫我的程序变成多线程的程序，哪位哥哥给帮我一下呀

太强了,没有做过啊,请问这些东西都在哪里能找到啊,
