MyRichEditCtrl.SetSelectionCharFormat(cf) MyRichEditCtrl.SetWindowText('I want colored text') Please see the different members of this structure in the MSDN. Actually this function passing a pointer to a CHARFORMAT structure containing the new character formatting attributes. Not only just changes the color of the text but also need to format the characters in the control.ĬRichEditCtrl provides a function SetSelectionCharFormat for that.

If its a valid double value, then only we need to update this with the edit control otherwise we can keep the previous value.Īfx_msg void OnChar(UINT nChar, UINT nRepCnt, UINT nFlags) Within the WM_CAHR message handler we can backup the existing value and within the EN_UPDATE message handler we can check the modified value. Then we need to put a handler for WM_CHAR and EN_UPDATE messages for our custom edit class. How shall we do it? Just a trick! 🙂įirst of all we have to a derive a new CEdit class to our project and make a control of that on our window. That means the edit box do not accept more than one.

Have you ever face a situation to make an edit box that support only floating point numbers.
