Typing without echo into a text box

[=?Utf-8?B?UmF5IE1pdGNoZWxs?=]

Hello,

I'm using a RichTextBox (but maybe something else would be more
appropriate). When I type something into it I don't want what I type to show
up automatically. Instead, I want to catch each keystroke and manually
selectively write the characters into it under program control. I can catch
the keystrokes fine, but how do I keep them from showing up automatically as
I type them?

Thanks,
Ray

I figured it out. Thanks anyway:
private void rtfTerminal_KeyDown(object sender, KeyEventArgs e)
{
// prevent echo into control
e.SuppressKeyPress = true;
// Show in logging text box
Log(LogMsgType.Outgoing,
Convert.ToString(Convert.ToChar(e.KeyValue)));
}
