The EN_MSGFILTER notification message notifies a rich edit control's parent window of a keyboard or mouse event in the control. A rich edit control sends this notification message in the form of a WM_NOTIFY message.
EN_MSGFILTER
wParam = (WPARAM) (UINT) uID;
lParam = (LPARAM) (MSGFILTER) lpMsgFilter;
Parameters
uID
Identifier of the rich edit control.
lpMsgFilter
Pointer to a MSGFILTER structure containing information about the keyboard or mouse message. If the parent window modifies this structure and returns a nonzero value, the modified message is processed instead of the original one.
Return Values
