MLM_QUERYFIRSTCHAR

This message queries the first visible character.

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

iptFVC (IPT) - return

First visible character.

Remarks

Returns the insertion point immediately preceding the character visible in the upper left-hand corner of the screen. If a partial character is displayed, that character counts as the first visible character.

Note: In situations where no character is visible, because the text is scrolled to the right beyond the end of the top line, this returns the insertion point of the last character on the line (EOL not considered). In situations where there are no characters on the line, the insertion point at the beginning is returned.

Default Processing

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