CEdit::LineLength
Call this function to retrieve the length of a line in an edit control.
int LineLength(
int nLine = -1
) const;
Параметры
- 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.
Возвращаемое значение
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.
Заметки
Use the LineIndex member function to retrieve a character index for a given line number within a multiple-line edit control.
