C# cross-thread call problem

Question

I\'m writing a form app in c# and I need to be able to change the contents of a Rich Text Box from any thread, I tried using a delegate and InvokeRe

Answer 1

Try this - where you call the same method if an invoke is required.

public void UpdateSub(string message)
{
    if (!subDisplay.subBox.InvokeRequired)
    {
        subDisplay.subBox.Text = message;
    }
    else
    {
        var d = new UpdateFormText(UpdateSub);
        Invoke(d, new object[] { message });
    }
}

Where UpdateFormText is the delegate

public delegate void UpdateFormText(string message);
