帮忙看下多行编辑框的问题

[djh512]

for(i   =   0;   i   < m_edit3.GetLineCount();   i++) 
{
       for(int j =0; j < MaxPLength; j++)
	  buffer[j] = '\0';
       int   len   =   m_edit3.LineLength(i);   
       memset(buffer,   0,   len   +   1);   
      int   n   =   m_edit3.GetLine(i,   buffer,   len);   
      buffer[n]   =   '\0';   
      MessageBox(buffer);

我在多行编辑框输入的是
S->aH
H->aMd
结果MessageBox出来的结果第一次是对的，第二次错了
为H->aM
问下问题在哪 请大家指教

for(int i   =   0;   i   < m_edit3.GetLineCount();   i++) 
	{
		for(int j =0; j < MaxPLength; j++)
			buffer[j] = '\0';
		int   len   =   m_edit3.LineLength(m_edit3.LineIndex(i));   
		memset(buffer,   0,   len   +   1);   
		int   n   =   m_edit3.GetLine(i,   buffer,   len);   
		buffer[n]   =   '\0';   
		MessageBox(buffer);
	}

int len = m_edit3.LineLength(m_edit3.LineIndex(i));
改为这句话
