This message returns the first insertion point on a given line.
Syntax
param1 ULONG ulReserved; /* Reserved value, should be 0. */ param2 ULONG ulReserved; /* Reserved value, should be 0. */
Parameters
- lLineNum (LONG) - input
- Line number of interest.
- ulReserved (ULONG) - input
- Reserved value, should be 0.
Returns
- iptFirst (IPT) - return
- First insertion point on line.
Remarks=
For any line number, the insertion point just before the first character on that line is returned. If the line number is -1, the line containing the cursor is used.
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.
Default Processing
The default window procedure takes no action on this message, other than to set iptFirst to 0.
