I am trying to use TaskbarNotifier, a skinnable MSN Messenger-like popup in C# in my project, I have a problem in the cs file that comes with the TaskbarNotifier.

At the line:
SetBounds(WorkAreaRectangle.Right-BackgroundBitmap.Width-17, WorkAreaRectangle.Bottom-1, BackgroundBitmap.Width, 0);

I get an error saying:
Cross-thread operation not valid: Control '' accessed from a thread other than the thread it was created on.

How can I bypass it? I have no clue.
Thanks

are you doing things in another thread? (Using a backgroundworker?)

use the Dispatcher to invoke your code on the ui thread.

example:

C#

public void MyMethod()
{
    if(!Dispatcher.CurrentDispatcher.CheckAccess())
    {
        Dispatcher.CurrentDispatcher.Invoke((Action)MyMethod, null);
        return;
    }
}

You cannot call anything related to UI from non-UI thread. Instead, you need to use the method Invoke or BeginInvoke of System.Windows.Threading.Dispatcher (for both Forms or WPF) or System.Windows.Forms.Control (Forms only).

You will find detailed explanation of how it works and code samples in my past answers:
Control.Invoke() vs. Control.BeginInvoke()[^],
