Hi. &nbsp;I want to restrict my CEdit box to numeric values only, but I also want to allow negative numbers. &nbsp;Using the ES_NUMBER flag doesn't allow anything below 0. &nbsp;Anybody know if there is a way to do this with a flag or do I need to make it a regular CEdit and check the values myself?<br />
Thanks.
