This system-provided window procedure processes the actions on an entry field control (WC_ENTRYFIELD).

Purpose

An entry field control is a rectangular window that displays a single line of text that the operator can edit. When it has the focus, the cursor marks the current insertion or replacement point.

When working with entry fields, the WM_CONTROL message is of major concern. An entry-field control communicates with its owner by sending WM_CONTROL messages. It contains a notification code in MP1 and a handle to the current entry field in MP2. The return value for WM_CONTROL is 0. Notification codes are denoted by an EN prefix.

For entry field control data see, ENTRYFDATA.
