类似VC6.0调试窗口的自动滚动条问题

[hustlotus]

随着程序的运行，调试窗口的文字不自动往下滚，望高手指教！！！

void CTestDlg::AppResultString(CString str)
{
	CEdit *pEdit = (CEdit *)GetDlgItem(IDC_OUTPUT);     // Edit控件
	
	CString   strBuffer;    // current contents of edit control
	if (pEdit->GetLineCount() < 100 )    // 100是限制最大行数
		pEdit->GetWindowText (strBuffer);
  // Append string
  if (!strBuffer.IsEmpty())
		strBuffer += "\r\n";
	
	COleDateTime dt = COleDateTime::GetCurrentTime();
	CString time = dt.Format("%H:%M:%S");
	strBuffer += time;
	strBuffer += "    ";
  strBuffer += str;
	pEdit->SetWindowText (strBuffer);
	
  // Scroll the edit control
	pEdit->LineScroll ( pEdit->GetLineCount(), 0);
}
