response to carriage return in Edit control

[zhuang]

I'd like to do something when the text in an Edit control is entered and the return is hit. What message I have to handle?

You have to place your code in the PreTranslateMessage() function as follows :

// looking for keydown message, where key is ENTER
// and the focus is on the edit control in question
if (pMSG->message == WM_KEYDOWN && pMsg->wParam == VK_RETURN && GetFocus() == GetDlgItem(IDC_EDIT_CONTROL_ID))
{
// enter pressed in the edit control, handle it here
return true ;
}
return BaseClass::PreTranslateMessage()

The code would close the Dialog after pressing enter. But I'd like to keep the dialog open after hitting enter in the Edit control. Any further idea?

The code I posted will only intercept the ENTER key when th focus is on the edit control, to stop ENTER fromclosing your dialog box, you will need to override the OnOK() function, as pressing ENTER is mapped to this control if the default button in your dialog is the IDOK button. IF you do override it, you will have to decide when to call the base class OnOK() to close the dislog box.
