代码实现：

Private Sub Command1_Click() Dim mrc As ADODB.Recordset

txtsql = \用户名,标识 from 用户 where 用户名='\& Trim(Text1.Text) & \ Set mrc = ExecuteSQL(txtsql) If mrc.EOF = True Then

MsgBox \用户名错误！\警告\ Text1.SetFocus 'Text1.SelStart = 0

username = mrc.Fields(0) qxstra = mrc.Fields(1) mrc.Close

txtsql = \密码 from 用户 where 密码='\ Set mrc = ExecuteSQL(txtsql) If mrc.EOF = True Then

MsgBox \密码错误！\ Text2.SetFocus 'Text2.SelStart = 0
