مشکل در BackGroundWorker

[hosein320]

سلام
این خطا برای چیه که پیش میاد

The calling thread cannot access this object because a different thread owns it.
من کد رو وقتی داخل بک گراند ورکر میزارم این خطا میاد
ولی وقتی معمولی استفاده میکنم مشکلی نیست و راحت اجرا میشه

از invoke استفاده کنید یا اینو بزارین تو فرم لود:

CheckForIllegalCrossThreadCalls = False

از متد Invoke استفاده کن:


' The following example demonstrates the 'Invoke(Delegate)' method of 'Control class.
' A 'ListBox' and a 'Button' control are added to a form, containing a delegate
' which encapsulates a method that adds items to the listbox.This function is executed
' on the thread that owns the underlying handle of the form. When user clicks on button
' the above delegate is executed using 'Invoke' method.
