CEdit::LineFromChar

Syntax

int LineFromChar( int nIndex = -1 ) const;

Parameters

nIndex

Contains the zero-based index value for the desired character in the text of the edit control, or contains -1. If nIndex is -1, it specifies the current line, i.e., the line that contains the caret.

Remarks

Retrieves the line number of the line that contains the specified character index. A character index is the number of characters from the beginning of the edit control.

This member function is only used by multiple-line edit controls.

Return Value

The zero-based line number of the line containing the character index specified by nIndex. If nIndex is -1, the number of the line that contains the first character of the selection is returned. If there is no selection, the current line number is returned.
