I have a modal dialog which has an Edit control and
a radio box.  Whenever I hit carriage return when the Edit
control or a radio box button has focus, it causes the
dialog to close.  How can I stop this from happening?  I
would rather have the carriage returns ignored.

This is the function of a dialog box. When you press Return key, it will activate the default pushbutton, such as the OK or Cancel button. Try overriding CDialog::OnKeyDown() (or OnKeyUp). When you detect it is a Return key, do nothing. Otherwise, call the base class function CDialog::OnKeyDown().

I overrode the CDialog::OnKeyDown() however this function is
not being called when I type in the edit contol.

Yes, because the CEdit::OnKeyDown() is called in this case. Do you mean this method works when the radio button has focus and it does not when the edit control has focus?

Hi kaplan1,

The messages OnKeyDown(), OnKeyUp()... won't be called for a modal dialog box.

Check out Article ID: Q126874 in Microsoft KB for more info
PRB: Modal Dialog Box Prevents Calls to PreTranslateMessage

The article also suggests a solution, which if implemented will allow messages to be sent to the dialog box. Then you can trap the OnKeyDown() message... & check for the Return key.

Hope this helps
