    dim v_date = datetext.text     dim v_username = usertext.text     dim v_phone = phonetext.text     dim v_email = emailtext.text     dim v_category = categorylist.text     dim v_short = shorttext.text     dim v_long = longtext.value      dim conn oledbconnection = new oledbconnection("provider=""********"";user id=" & struserid & ";data source=" & strdatabase & ";password=" & strpsswd)     conn.open()      dim classifiedstr oledbcommand = new oledbcommand("insert tablename (date, username, phonenbr, email, category, description, fulldescription) values(@v_date, lower(@v_username), @v_phone, @v_email, @v_category, @v_short, @v_long)", conn)     classifiedstr.parameters.add("@v_date", oledbtype.date).value = v_date     classifiedstr.parameters.add("@v_username", oledbtype.varchar).value = v_username     classifiedstr.parameters.add("@v_phone", oledbtype.varchar).value = v_phone     classifiedstr.parameters.add("@v_email", oledbtype.varchar).value = v_email     classifiedstr.parameters.add("@v_category", oledbtype.varchar).value = v_category     classifiedstr.parameters.add("@v_short", oledbtype.varchar).value = v_short     classifiedstr.parameters.add("@v_long", oledbtype.varchar).value = v_long      classifiedstr.executenonquery()     conn.close()

you don't need use data adaptor, you're not returning , data client, instead, use executenonquery(), (with added parametrisation):

protected sub insert_click(sender object, e eventargs) handles insert.click     using conn new oledbconnection("provider=""*********"";user id=" & struserid & ";data source=" & strdatabase & ";password=" & strpsswd)         conn.open()          using classifiedstr new oledbcommand("insert t_classifieds (""date"", username, phonenbr, email, category, description, fulldescription) values(@v_date, lower(@v_username), @v_phone, @v_email, @v_category, @v_short, @v_long)", conn)             classifiedstr.parameters.add("@v_date", oledbtype.date).value = datetext.text             classifiedstr.parameters.add("@v_username", oledbtype.varchar).value  = usertext.text             classifiedstr.parameters.add("@v_phone", oledbtype.varchar).value = phonetext.text             classifiedstr.parameters.add("@v_email", oledbtype.varchar).value = emailtext.text             classifiedstr.parameters.add("@v_category", oledbtype.varchar).value = categorylist.text             classifiedstr.parameters.add("@v_short", oledbtype.varchar).value = shorttext.text             classifiedstr.parameters.add("@v_long", oledbtype.varchar).value = longtext.value              classifiedstr.executenonquery()         end using     end using end sub
