Q.  How do I set the default button in a dialog when using MFC?

A.  Usually its the "OK" button.

This function does the trick:

int CMyDialogClass::SetDefaultButton(const DWORD nNewId) { DWORD nPrevId; nPrevId = GetDefID(); // Its not automatic - we have to remove the border from the old button SendDlgItemMessage(nPrevId, BM_SETSTYLE, BS_PUSHBUTTON, (LPARAM)TRUE); SetDefID(nNewId); // Likewise, add a border to the new one SendDlgItemMessage(nNewId, BM_SETSTYLE, BS_DEFPUSHBUTTON, (LPARAM)TRUE); return nPrevId; }
