int LineLength( int nLine = -1 ) const;
Return Value
When LineLength is called for a multiple-line edit control, the return value is the length (in bytes) of the line specified by nLine. When LineLength is called for a single-line edit control, the return value is the length (in bytes) of the text in the edit control.
Parameters
nLine
Specifies the character index of a character in the line whose length is to be retrieved. If this parameter is –1, the length of the current line (the line that contains the caret) is returned, not including the length of any selected text within the line. When LineLength is called for a single-line edit control, this parameter is ignored.
Remarks
Call this function to retrieve the length of a line in a rich edit control.
Use the LineIndex member function to retrieve a character index for a given line number within this CRichEditCtrl object.
