这个程序抛出一个异常，就像我在标题时不时。我在vb设置中检查了交叉线程。这就是为什么会发生这种情况的原因？我不太了解这个话题，试着离散。感谢。

Public Sub thread_A()

hi, this program throws a exception along the lines of what i wrote in the title now and then. I have check for cross threading off in vb settings. is this the reason why this is happening? I do not know too much about this topic and try to be discrete. thanks.
