Multi-line Entry Field Control

All the notification messages and control messages for the multi-line entry field control can be used even in the DBCS PM.

The considerations for mixed string manipulation explained in String Manipulation, are required although the multi-line entry field control (but not single line entry field control) tries to minimize impacts of error cases. For example:

• If the new anchor or cursor point in MLM_SETSEL points to the second byte of a DBCS character, the point will be set to one byte left, i.e. at the first byte of the DBCS character,

• If a string passed from the application ends with the first byte of a DBCS character, the request is accepted but the fragment byte of the DBCS character is discarded.
