改成
If flt > "" Then
Dim nids As String = dt.GetComboListString("_Identify", flt)
nids = dt.GetComboListString("_Identify", "_Identify not in (\'" & nids.replace("|", "\',\'") & "\')")
If flt > "" AndAlso notchecked > 0 Then
tb1.Filter = "_Identify not In (\'" & nids.Replace("|","\',\'") & "\')"
Else
tb1.Filter = (1 = 2)
End If
Else
tb1.Filter = flt
End If

下面表达式代码出错：
Dim nids As String = tb1.DataTable.GetComboListString("系统编号",flt & " And 招标审核 = \'通过\'")
If flt > "" AndAlso notchecked > 0 Then
tb1.Filter = "系统编号 In (\'" & nids.Replace("|","\',\'") & "\')"
Else
tb1.Filter = (1 = 2)
End If
提示：
.NET Framework 版本：2.0.50727.8762
Foxtable 版本：2018.10.9.1
错误所在事件：窗口,投标分配台帐,Trv_sxs,AfterCheckNode
详细错误信息：
语法错误:“And”运算符前缺少操作数。
