锁定用户函数

我们经常会看到在BBS里面禁止用户发贴,或锁定用户不能登录等,下面我们就来看看这些功能是怎么用程序实现的吧.
Sub Lockuser()
 Dim UserStatus
 If XmlDoc.documentElement.selectSingleNode("userstatus") is Nothing Then
  Messenge = "参数非法，中止请求。"
  Status = 1
  Exit Sub
 ElseIf Not IsNumeric(XmlDoc.documentElement.selectSingleNode("userstatus").text) Then
  Messenge = "参数非法，中止请求。"
  Status = 1
  Exit Sub
 Else
  UserStatus = Clng(XmlDoc.documentElement.selectSingleNode("userstatus").text)
 End If
 If UserStatus = 0 Then
  Newasp.Execute ("UPDATE NC_User SET UserLock=0 WHERE Username='" & UserName & "'")
 Else
  Newasp.Execute ("UPDATE NC_User SET UserLock=1 WHERE Username='" & UserName & "'")
 End If
 Status = 0
End Sub
