Question

所以我在vb.net中运行了多个线程。我需要知道，如何添加到“在不同的线程中创建”的列表框？我似乎无法克服这个错误！

确切错误：

    System.InvalidOperationException occurred
  HResult=0x80131509
  Message=Cross-thread operation not valid: Control 'ListBox2' accessed from a thread other than the thread it was created on.
  Source=System.Windows.Forms

你们有什么建议我去解决这样的错误？
