Is it imperative that the textbox contains the escape characters? If it were me, I'd show them on the form outside the textbox, like:
% <text box> ^ And then add them in code like: string card = "%" + cardNumber.Text + "^"; That way, the user can see it like that but they only have to type the card number not the delimiters.

However, if I want someone to be able to type into it, they have to type a % first and the a carrot at the end. Is there anyway to avoid that...here is the code...I didn't write it, butit is how the boss wants it: if (e.KeyChar == '^') IsSwipeStarted = false; if (IsSwipeStarted) { if (char.IsNumber(e.KeyChar) == false) e.Handled = true; } else e.Handled = true; if (e.KeyChar == '%') IsSwipeStarted = true; if (e.KeyChar == '\r') btnCardParse_Click(null, null); TIA: Rick [Non-text portions of this message have been removed]
