２．给编辑框添加获得焦点和失去焦点的消息映射

BEGIN_MESSAGE_MAP(CSDProDlg, CDialog)
 //{{AFX_MSG_MAP(CSDProDlg)

 ON_EN_KILLFOCUS(IDC_EDIT4, OnKillfocusEdit4)
 ON_EN_SETFOCUS(IDC_EDIT4, OnSetfocusEdit4)

 //}}AFX_MSG_MAP
END_MESSAGE_MAP()

３．在消息函数中添加SipShowIM（SIPF_OFF／SIPF_ON）；

void CXXX::OnKillfocusEdit4()
{
 // TODO: Add your control notification handler code here
 SipShowIM(SIPF_OFF); 
}

void CXXX::OnSetfocusEdit4()
{
 // TODO: Add your control notification handler code here
 SipShowIM(SIPF_ON);
}
