推荐答案

嘿...这很容易做到.

只需在每次按键上检查字符的长度即可.如果找到限制，则将焦点设置到下一个文本框.

您还需要跟踪BackSpace并对其进行相反的操作.

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.

处理所有编辑框的EN_CHANGE通知.
调用lParam上的GetDlgItemText以获取文本并检查其长度.
如果长度为5，则调用SetFocus将闪烁的光标设置到下一个编辑框.
GetDlgItem为您提供控件的句柄.

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.
