CRichEditCtrl::GetLine

  • 项目

int GetLine( int nIndex**, LPTSTR** lpszBuffer ) const;

int GetLine( int nIndex**, LPTSTR** lpszBuffer**, int** nMaxLength ) const;

Return Value

The number of characters copied into lpszBuffer.

Parameters

nIndex

Zero-based index of the line to retrieve.

lpszBuffer

Points to the buffer to receive the text. The first word of the buffer must specify the maximum number of bytes that can be copied into the buffer.

nMaxLength

Maximum number of characters that can be copied into lpszBuffer. The second form of GetLine places this value into the first word of the buffer specified by lpszBuffer.

Remarks

Call this function to retrieve a line of text from this CRichEditCtrl object. The copied line does not contain a terminating null character.

Note   Because the first word of the buffer stores the number of characters to be copied, make sure that your buffer is at least 4 bytes long.

For more information, see in the Win32 documentation.
