Right, that's why I was asking about the WinAPI RichEdit control. Any VB 
RichTextBox will be based on (some version of) the WinAPI RichEdit 
Control, though it might not support all of the RichEdit control's 
features. But using calls to the API, a RichEdit control
can be used in place of a RichTextBox.

And all I wanted to know is if there's anybody who knows the RichEdit 
control well enough to tell me what the global toggle for hidden text 
is, assuming it exists, which it almost certainly does.
