请问大虾，下面这段代码里能否分析出用户名和密码！！
Private Sub cmdOK_Click()
    Dim txtSQL As String
    Dim mrc As ADODB.Recordset
    Dim MsgText As String
    'ToDo: create test for correct password
    'check for correct password
   
    UserName = ""
    If Trim(txtUserName.Text = "") Then
        MsgBox "没有这个用户，请重新输入用户名！", vbOKOnly + vbExclamation, "警告"
        txtUserName.SetFocus
    Else
        txtSQL = "select * from user_Info where user_ID = '" & txtUserName.Text & "'"
        Set mrc = ExecuteSQL(txtSQL, MsgText)
        If mrc.EOF = True Then
            MsgBox "没有这个用户，请重新输入用户名!", vbOKOnly + vbExclamation, "警告"
            txtUserName.SetFocus
        Else
            If Trim(mrc.Fields(1)) = Trim(txtPassword.Text) Then
                OK = True
                mrc.Close
                Me.Hide
                UserName = Trim(txtUserName.Text)
            Else
                MsgBox "输入密码不正确，请重新输入！", vbOKOnly + vbExclamation, "警告"
                txtPassword.SetFocus
                txtPassword.Text = ""
            End If
        End If
    End If
   
    miCount = miCount + 1
    If miCount = 3 Then
        Me.Hide
    End If
    Exit Sub
End Sub

Private Sub cmdOK_Click()
    Dim txtSQL As String
    Dim mrc As ADODB.Recordset
    Dim MsgText As String
    'ToDo: create test for correct password
    'check for correct password
   
    UserName = ""
nCount=0
    If Trim(txtUserName.Text = "") Then
        MsgBox "没有这个用户，请重新输入用户名！", vbOKOnly + vbExclamation, "警告"
        txtUserName.SetFocus
         exit sub
      end if
  
If Trim(txtpassword.Text = "") Then
        MsgBox "没有这个用户，请重新输入用户名！", vbOKOnly + vbExclamation, "警告"
        txtpassword.SetFocus
         exit sub
      end if

  
    txtSQL = "select * from user_Info where user_ID = '" & txtUserName.Text & "'and password='"&txtpassword.text &"'"
        Set mrc = ExecuteSQL(txtSQL, MsgText)
        If not mrc.EOF  Then
           frmXXX.show
          else
            MsgBox "用户名或密码错误!", vbOKOnly + vbExclamation, "警告"
            txtUserName.SetFocus
            exit sub
        nCount=nCount+1
        if nCount>3 then
          msgbox"错误超过3个","vbokonly","提示"
           end sub
         end if
        end if

不能分析出
不过改改代码可以得到所有的用户名和密码

这位大虾能否帮我看看，我初学这个东西，想就这个系统学习！谢谢啊!

建议你先学习ADO和SQL

好的，谢谢啊！
