Recently, I was working on a diagnostic software which requires a Edit Control used for HEX/DEC numbers input. The CEdit that comes with MFC is not so good for this job, as it can not prevent the user from typing an invalid HEX number.
Therefore, I created the CHexEdit control derived from CEdit for HEX/DEC numbers input, it is very easy to use.
