- lineNumber
- Int32
The line for which to get the index of its first character.
Returns
The zero-based character index in the specified line.
Remarks
If the lineNum parameter is negative, GetFirstCharIndexFromLine returns 0. If the lineNum parameter exceeds the number of lines in the control, GetFirstCharIndexFromLine returns the first character index for the last line in the control.
GetFirstCharIndexFromLine returns the first character index of a physical line. The physical line is the displayed line, not the assigned line. The number of displayed lines can be greater than the number of assigned lines due to word wrap. For example, if you assign two long lines to a RichTextBox control and set Multiline and WordWrap to true, the two long assigned lines result in four physical (or displayed lines).
