Yes, you can limit length of text in textbox by sending EM_SETLIMITTEXT message. If you need single character limit :

const int maximum_length = 1;
SendMessage(hEdit, EM_SETLIMITTEXT, maximum_length, 0);

note: EM_LIMITTEXT and EM_SETLIMITTEXT are identifiers for the same message. They are constants with same numeric value. Two identifiers exist for historical reasons. (EM_SETLIMITTEXT is new from Win95/WinNT 4.0 SDK)

For edit use EM_LIMITTEXT (or equivalent EM_SETLIMITTEXT) message. For richedit you need EM_LIMITTEXT or EM_EXLIMITTEXT for text length values greater than 64000

If you use mfc than you need CEdit::LimitText or CRichEditCtrl::LimitText
