[RESOLVED] Invoke RichTextBox From Another Thread

[noahssite]

Hello, I modified some code I found after a search on google. The original code was written my jmc. It originally, on the original code, a void. I tried to modify it to work with a string[].

I am currently getting a Parameter count error message.

private delegate string[] GetRtbSongsLinesDelegate(object item);
        private string[] GetRtbSongsLines(object item)
        {
            if (this.rtbSongs.InvokeRequired)
            {
                // This is a worker thread so delegate the task.
                this.rtbSongs.Invoke(new GetRtbSongsLinesDelegate(this.GetRtbSongsLines),null);
            }
            else
            {
                // This is the UI thread so perform the task.
                return this.rtbSongs.Lines;
            }
            return null;
        }

I am calling this using:

GetRtbSongsLines(null)

For example:

if(GetRtbSongsLines(null).length > 0){
//There are more than 0 lines
}

What's wrong?
