Dim thr As New Thread(AddressOf 循环)
thr.Start("a")
End Sub
Sub 循环(a() As String)
'这里随你干什么循环也行
For Each i As String In a
MsgBox(i)
Next
End Sub
看懂了吧 参数只能有一个 也可以不是数组,在a() As String的a后面去掉括号就行
过程只需要1个,线程你要多少就需要创建多少,这个可以用循环来创建:
Dim Thd(99) As Thread
For i As Integer =0 to 99
Thd(i)=New Thread(AddressOf Start)
Thd(i).Start()
Next
如果你不需要保留这些线程的引用
那个数组也可以省略掉
直接在循环中(New Thread(AddressOf Start)).Start()就行了

代码不是在IDE中打的,可能有细微小错误
你这个是操作多个窗口还是操作单个窗口
单个窗口的话,没必要创建多个对象,1个就够了。
如果特殊情况下需要创建多个大漠插件的对象,承载对象的变量可设置成数组型,或者可更换成模块去创建多个对象
我以前用过:如图,这个模块可以实现,需要的话精益论坛上有 搜索下
代码的写法如下:
1、先创建个全局变量的对象数组
2、如下
多线程一般是不推荐用的,因为线程之间如果有共享资源的话会引起竞争,需要加锁处理;而且线程间没有时序关系,所以你在调试中可能会出现异步处理结束顺序与开始处理顺序不一致的情况(我在调试中已经发现该问题)。
针对你提出的这个问题,采用了多线程处理,利用的是BackgroundWorker也就是异步处理控件进行了处理。
代码已经经过调试通过。欢迎交流,如有问题,留下QQ或其他联系方式。
代码如下,并附程序截图。
