vb.net - Converting a OleDbDataReader to a String to display a COUNT command in List View -


i want display in listview count of specific employee name whilst using 2 ms access queries. count being displayed 0, 1 or 2 there many none "----" values in database.

the command binded radiobutton:

private sub radiobutton2_click(sender object, e eventargs) handles radiobutton2.click            dim con new oledbconnection("provider=microsoft.jet.oledb.4.0;data source=" & application.startuppath & "\sheetlog.mdb;jet oledb:database password = 'password';")         con.open()          dim try2 string = "----"         dim try3 string         dim oledbcmd, oledbcmd2 oledbcommand         dim cmd, cmd2 string           cmd = "select distinct empname sheet"         oledbcmd = new oledbcommand(cmd, con)         dim oledbreader oledbdatareader = oledbcmd.executereader()          listview1.clear()         listview1.gridlines = true         listview1.fullrowselect = true         listview1.view = view.details         listview1.multiselect = false         listview1.columns.add("employee name", 130)         listview1.columns.add("new", 80)         listview1.columns.add("rev1", 80)         listview1.columns.add("rev2", 80)         listview1.columns.add("rev3", 80)         listview1.columns.add("rev4", 80)         listview1.columns.add("rev5", 80)          while (oledbreader.read)              try3 = oledbreader("empname").tostring              cmd2 = "select count(new) cnew, count(rev1) crev1, count(rev2) crev2, count(rev3) crev3, count(rev4) crev4, count(rev5) crev5 sheet empname = '" & try3 & "' , rev1 <> '" & try2 & "' , rev2 <> '" & try2 & "' , rev3 <> '" & try2 & "'  , rev4 <> '" & try2 & "'  , rev5 <> '" & try2 & "'"              oledbcmd2 = new oledbcommand(cmd2, con)              dim oledbreader2 oledbdatareader = oledbcmd2.executereader()              while (oledbreader2.read)              listview1.items.add(oledbreader("empname"))                 .subitems.add(oledbreader2("cnew"))                 .subitems.add(oledbreader2("crev1"))                 .subitems.add(oledbreader2("crev2"))                 .subitems.add(oledbreader2("crev3"))                 .subitems.add(oledbreader2("crev4"))                 .subitems.add(oledbreader2("crev5"))             end          end while          end while           con.close()      end sub

i've been away vb.net bit, think need while(oledbreader2.read())for second datareader:

dim oledbreader2 oledbdatareader = oledbcmd2.executereader() ' think need here: while (oledbreader2.read)     listview1.items.add(oledbreader("empname"))         .subitems.add(oledbreader2("cnew"))         .subitems.add(oledbreader2("crev1"))         .subitems.add(oledbreader2("crev2"))         .subitems.add(oledbreader2("crev3"))         .subitems.add(oledbreader2("crev4"))         .subitems.add(oledbreader2("crev5"))     end end while
