Entering only letters in MFC

hey, im doing thisprogram, and in this textfield, i just want the user to enter in only letter, and not allow them to enter anything in but letters. i know the command for only entering in numbers is ES_NUMBER, but i havent been able to find out how to do that with letters instead of numbers. thanx

This should probably have been posted to the Windows forum.
Derive a new control from CEdit and call it CAlphaEdit. Overload the OnChar() method and check if characters entered were non-char, if so, block them.

Code:

---

class CAlphaEdit : public CEdit
{
protected:
    afx_msg void OnChar(UINT, UINT, UINT);
    DECLARE_MESSAGE_MAP()
};

BEGIN_MESSAGE_MAP(CSsnEdit, CEdit)
    ON_WM_CHAR()
END_MESSAGE_MAP()

void CAlphaEdit::OnChar(UINT nChar, UINT nRepCount, UINT nFlags)
{
    if (_istalpha(nChar))
        CEdit::OnChar(nChar, nRepCount, nFlags);
}

If you need anything else, or don't understand this example, post back.

im havin trouble using it on this one specific text box, i dont know how to do it

Are you using MFC? If so, try the solution above, I don't use MFC so I can't vouch for it.

If you are using the raw API, subclass the edit box and intercept each WM_CHAR message, if it contained a character I wanted, I'd forward the message to the edit box, if not, dump it.

If you don't know how to do that, post again.
