主题：[求助]timetrick 里面的代码问题

想在打开软件的时候预加载一些表。但是又的时候他会疯狂提示 表格已加载。。如何避免这种情况呢。

 If _UserGroup= "人事" Then
       
        Dim s1 As String = "人员信息表|外派服务协议登记表|综合奖惩记录表|组别结构表|PM绩效"
        Dim values1 As String()
        values1 = S1.Split("|")
        For Each tb As Table In Tables
            For I1 As Integer = 0 To Values1.Length - 1
                If Values1(I1)=tb.name Then
                    S1=s1.Replace(Values1(I1),"")
                    'MsgBox(Values1(I1))
                End If
            Next
        Next
        S1=S1.TRIM("|")
        If s1<>"" Then
            If DataTables.Contains(s1) = False Then
                DataTables.Load(S1)
            End If
        End If
