#define INCL_WINMLE
 
MLM_QUERYFORMATTEXTLENGTH
mp1 = MPFROMLONG((LONG) lOffset);   /* offset of starting character */
mp2 = MPFROMLONG((LONG) cbChar);    /* characters to scan           */
 
An application sends an MLM_QUERYFORMATTEXTLENGTH message to retrieve the
length (in bytes) of a range of characters in multiple-line entry field
(MLE).
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
lOffset    Low and high word of mp1. Specifies the offset (number of
           characters from the beginning of the text) of the first character
           to count. If this parameter is set to -1, the current cursor
           position is used as the starting character.
 
cbChar     Low and high word of mp2. Specifies the number of characters to
           scan. If this parameter is set to -1, the entire text is
           scanned.
 
Return Value
 
The return value is a 32-bit value (ULONG) that specifies the number of
bytes in the specified range of characters.
 
Comments
 
The number of bytes returned for any end-of-line characters is determined by
the format specified by the MLM_FORMAT message. This format can be one of
the following values:
 
Format         Description
────────────────────────────────────────────────────────────────────────────
MLFIE_CFTEXT   The end-of-line character is formatted as carriage-return/
               linefeed characters (2 bytes).
 
MLFIE_NOTRANS  The end-of-line character is formatted as a linefeed
               character (1 byte).
 
MLFIE_WINFMT   The end-of-line character for hard line breaks is formatted
               as carriage-return/linefeed characters (2 bytes). The
               end-of-line character for soft line breaks (line breaks
               caused by word-wrapping) is formatted as
               carriage-return/carriage-return/linefeed characters (3
               bytes).
