{{DISPLAYTITLE:MLM_QUERYFIRSTCHAR}}
This message queries the first visible character.

==Syntax==
<pre>
param1
ULONG ulReserved; /* Reserved value, should be 0. */

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

==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.
