Retrieves a line of text from this CRichEditCtrl object.
int GetLine(
int nIndex,
LPTSTR lpszBuffer
) const;
int GetLine(
int nIndex,
LPTSTR lpszBuffer,
int nMaxLength
) const;
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.
Return Value
The number of characters copied into lpszBuffer.
Remarks
The copied line does not contain a terminating null character.
备注
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 EM_GETLINE in the Windows SDK.
