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
这一句 If mrc.EOF = True Then 出错提示： 对象变量或with块变量未设置
请问怎么解决？？回答的好有追加！！谢谢！
