Two parallel running thread want to update a label on WinFom

To get around the threading-violation, Winforms provides these helper-methods:

BeginInvoke, EndInvoke, Invoke, InvokeRequired.

public delegate void InvokeDelegate();

private void Invoke_Click(object sender, EventArgs e)

{

myTextBox.BeginInvoke(new InvokeDelegate(InvokeMethod));

}

public void InvokeMethod()

{

myTextBox.Text = "Executed the given delegate";

}
