feature

feature • store key-value • on memory running • edit stored values

store key-values

store key-value defined same method as "Hash" –[](key) –store(key, value) –delete(key)

store key-value – find(1) YAML.load( @app.WorksheetFunction.VLookup (YAML.dump(key), @sheet.Range(KEYVALUE_COLS), 2, false ))

store key-value – find(2) @sheet.range(KEY_COLS).Find(YAML.dump(key), @app.ActiveCell, -4163, #xlValues, 1, #xlWhole, 1, #xlByRows, 1, #xlNext, true, false)

store key-value – insert get tail row offset in worksheet max_row = @sheet.UsedRange.Row + @sheet.UsedRange.Rows.count @sheet.range("A#{max_row}").value = YAML.dump(key) @sheet.range("B#{max_row}").value = YAML.dump(value)

store key-value – update range = find(key) range.offset(0, 1).value = YAML.dump(value)

store key-value - delete target_row = find(key).Row sheet.Range("#{target_row}:#{target_row}").Delet e (-4162)

on memory running

on memory running • if call XLS_KVS#new –create XLS_KVS::Hash instance –lunch Microsoft Excel • if call XLS_KVS::Hash#Close –save&close Excel Workbook –unload Microsoft Excel

edit stored values

edit stored values kvs = XLS_KVS.load(@xls_file, 1, false) kvs.store(1, [Time.now, 'new running', 19]) kvs.store(2, [Time.now, 'I am Koshiba', 9]) kvs.store(3, self)

edit stored values kvs = XLS_KVS.load(@xls_file, 1, false) kvs.store(1, [Time.now, 'new running', 19]) kvs.store(2, [Time.now, 'I am Koshiba', 9]) kvs.store(3, self) edit directly!

edit stored values kvs = XLS_KVS.load(@xls_file, 1, false) kvs.store(1, [Time.now, 'new running', 19]) Excel is useful kvs.store(2, [Time.now, 'I am Koshiba', 9]) for many people! kvs.store(3, self) edit directly! engineers, business persons students, my mother, etc

edit stored values Microsoft Excel is many people's friend
