MS Uses it for years. Type your Product Code starting in the first box, the next key (after 5 chars) lands into the next box, etc etc Any idea how to do that?

Solution 1

Hey... this is very easy to do.

Just on every keypress, check the length of the characters. If you find the limit, set focus to the next textbox.

You also need to track BackSpaces and do the reverse for it.

Solution 2

Handle the EN_CHANGE Notification for all edit boxes.
Call GetDlgItemText on the lParam to get the text and check its length.
If the length is 5, call SetFocus to set the blinking cursor to the next edit box.
GetDlgItem gives you the handle to a control.
