[RESOLVED] VB 2010: Cross-thread problem with Progress Bar

Alright so I finished my first program and I'm working on my second. I copied over a bunch of stuff and now the only problem I am having is this error with my progress bar.

"Cross-thread operation not valid: Control 'ProgressBar1' accessed from a thread other than the thread it was created on."

I've fixed this before, but I can't quite remember. Here is the code it is being used by-

Code:

---

Private Sub BackgroundWorker1_ProgressChanged(ByVal sender As Object, ByVal e As System.ComponentModel.ProgressChangedEventArgs) Handles BackgroundWorker1.ProgressChanged

        ProgressBar1.Value = Convert.ToInt32(100 * P / 2)

    End Sub

---

Invoke the UI thread to access the progressbar properties.

vb Code:

ProgressBar1.Invoke(Sub() ProgressBar1.Value = Convert.ToInt32(100 * P / 2))

Thanks! Although, I found the problem once I read back through my code. The report progress was set to the wrong progress change.

The cross thread issue has more to do with threads trying to take action on threads that aren't their own.

That really did help though, on a totally different part of my program xD Thanks.

No problem, as long as you've got things figured out :)
