MLM_QUERYLINECOUNT

This message queries the number of lines of text.

Syntax

param1
ULONG ulReserved; /* Reserved value, should be 0. */

param2
ULONG ulReserved; /* Reserved value, should be 0. */

Parameters

ulReserved (ULONG) - input

Reserved value, should be 0.

ulReserved (ULONG) - input

Reserved value, should be 0.

Returns

ulLines (ULONG) - return

The number of lines of text.

Remarks

The term line means a line on the display after the application of word-wrap. It does not mean a line as defined by the CR LF line-break sequence. The multi-line edit control always maintains one CR LF line-break in the buffer, therefore the number of lines returned may be one greater than the number actually visible.

Default Processing

The default window procedure takes no action on this message, other than to set ulLines to 0.
