CEdit::LineLength

Syntax

int LineLength( int nLine = -1 ) const;

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

Retrieves the length of a line in an edit control.

Use the LineIndex member function to retrieve a character index for a given line number within a multiple-line edit control.

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.
