Call a method from UI in another Thread
Hi,
In a running thread (Async Backgroundworker) I wan't to get selected listbox items from the UI.
In my current code the background worker starts but when I call the method in the DOWORK it get's an exeption:
"Cross-thread operation not valid: Control 'listBox1' accessed from a thread other than the thread it was created on."
What is the solution?
I am a beginner...
