The IASEditBox interface, which has a global unique identifier (GUID) equal to IID_ASEDITBOX, extends the IASCharSpinner interface. An edit control has a programmatic identifier equal to APC_Edit.
Edit mode is entered when the user presses the ENTER key, or the application invokes IASEditBox::put_Editing(TRUE). When editing a particular character, the WM_COMMAND message is fired to the event sink whenever when the edit mode is exited. This happens when the user presses either the ENTER or ESCAPE key. The values of the wParam and lParam parameters that accompany the WM_COMMAND message are described in the following table.
