How to handle NM_RETURN in a dialog

It appears that NM_RETURN never gets sent if a list control is embedded in a dialog.  NM_DBLCLK definitely gets called, but NM_RETURN, when the focus is on an item in the list control never gets fired.  The only thing that gets fired is the default button handler.  I believe that the message never gets fired because I have tried to capture the message in pretranslate and it never captured the message.

Correct, the new controls (treeview and listview) don't appear to follow correct dialog controls semantics. They are really designed to be in a window and not in a dialog. To get around this problem, you need to set the default ID to a hidden button. The hidden button will be clicked when the user presses the return key. This function can tell if the focus came from the list control (through WM_SETFOCUS), if it is, then you can do whatever you like. Otherwise, you can then simulate the Ok button being pressed.

if (GetDlgItem(IDC_LIST)==SetFocus())
  OnOK();
else
  OnSearch();

Did the trick!!  This code was placed in the bn_clicked handler for the hidden button.
