    Else
        cmd.CommandText = "Select * from {员工资料} where " & cmb2.Value & " = \'" & cmb1.Value & "\'"
    End If
    dt = cmd.ExecuteReader() 
    Dim dst As WinForm.DataList = .Controls("DataList1")  
    dst.DataTable = dt
    dst.Build()
    .Controls("Label2").Text = dst.Count 
end with

劳驾贺老师了,此代码好像没有反应,请看查询表窗口的“筛选生成新表”按钮。
