RichTextBox

Question

Hi!  I'm an extreme newbie, so please be nice to me. :)
I'm working in Visual Studio Express 2008.  I have a RichTextBox control.  The following code compiles, but the text file doesn't actually appear in the control:
 

 

private void 
ftsMenuOpen_Click(object sender, System.EventArgs e)

{

if (ofdFile.ShowDialog() == DialogResult.OK)

{

ofdFile.DefaultExt = ".txt";

ofdFile.Filter = "Text Files|*.txt";

try

{

rtbFile.LoadFile(ofdFile.FileName, RichTextBoxStreamType.RichText);

}

catch (ArgumentException)

{

}

}

}

I would really appreciate it if you could perhaps help me out a little :)
Thanks
