By default the enter key means IDOK and esc key means IDCANCEL commands. So avoid this you have to override the followings functions as... void OnOK() { /* nothing to do */ } void OnCancel() { /* nothing to do */ } Try it... - NS -

You can override 2 function OnOK() (for ENTER) and OnCancel (for ESC). In override function, you don't call base function from class CDialog Example: void CMyDialog::OnOK() { //CDialog::OnOK(); } ----------------- conglt

The Esc key is automatically mapped to the IDCANCEL command. So you can get over that by overriding the handler to create an empty function. Your Enter key is probably calling the OnOK handler because your OK button has the default focus. Again you could override the IDOK handler and bypass the default action, but you should provide an alternative means of exiting yoru dialog (calling the CDialog::OnOk(), or EndDialog() functions), else your program will have no means of quitting.

Yes, I forgot that... You have to map WM_CLOSE and call EndDialog( 0 ) from there (OnClose fn) inorder to process the dialog close. - NS -

Hi mosali satish, maybe it is some helpful to you http://bobmoore.mvps.org/Win32/w32tip41.htm[^]

deal with the message "WM_KEYDOWN" in the function "PreTranslateMessage" like this: BOOL CYourDlg::PreTranslateMessage(MSG* pMsg) { // TODO: Add your specialized code here and/or call the base class if(pMsg->message == WM_KEYDOWN) { int nVitKey = (int)pMsg->wParam; if(nVitKey == VK_RETURN) return TRUE; else if(nVitKey == VK_ESCAPE) return TRUE; } return CDialog::PreTranslateMessage(pMsg); } than when you press the "enter"and"ESC" the dialog will not terminate. bambooshan
