Values Filled To Combobox

        FillCombobox(ComboBox1, "Select slno,custname,address,tinno,cstno from tbl_custinfo", "custname", "custname", "custname")

Listview Filled

Public Sub FillList1()

        sSql = "Select slno,custname,address,tinno,cstno from tbl_custinfo"

        With lstcust

            .Clear()

            .View = View.Details
