If you would like to realize update rows by only allowing delete and insert rows on DB, set operation might be helpful. For PHP, using array_diff function is really useful for realizing the operation. // we would like to insert '4', '5' and delete '2' in this example. // how to do this? $original_ids = array('1', '2', '3'); $new_ids = array('1', '3', '4', '5'); // one solution // 1) the key point is calculating subtract set. // 2) array_values is used only for re-numbering index. e.g. all index will be 0 origin sequence . // the result will be array(1){ [0] => '4', [0] => '5' } $ids_insert = array_values(array_diff($new_ids, $original_ids)); // the result will be array(1){ [0] => '2' } $ids_delete = array_values(array_diff($new_ids, $original_ids));

Just do this :) var ifc = new System.Drawing.Text.InstalledFontCollection(); foreach (var ff in ifc.Families) { Console.WriteLine(ff.Name); }

Here is a code for resizing image using Graphics2D. I also put bunch of rendering hints in the example code. Hope it helps for your understanding. private static BufferedImage resize(BufferedImage image, int width, int height) { BufferedImage shrinkImage = new BufferedImage(width,height, image.getType()); Graphics2D g2d = shrinkImage.createGraphics(); // rendering hints g2d.setRenderingHint(KEY_ALPHA_INTERPOLATION, VALUE_ALPHA_INTERPOLATION_QUALITY); g2d.setRenderingHint(KEY_ANTIALIASING, VALUE_ANTIALIAS_ON); g2d.setRenderingHint(KEY_COLOR_RENDERING, VALUE_COLOR_RENDER_QUALITY); g2d.setRenderingHint(KEY_DITHERING, VALUE_DITHER_ENABLE); g2d.setRenderingHint(KEY_TEXT_ANTIALIASING, VALUE_TEXT_ANTIALIAS_ON); g2d.setRenderingHint(KEY_RENDERING, VALUE_RENDER_QUALITY); g2d.setRenderingHint(KEY_INTERPOLATION, VALUE_INTERPOLATION_BILINEAR); g2d.setRenderingHint(KEY_FRACTIONALMETRICS, VALUE_FRACTIONALME

C#でExcelファイルを読み書きするためには、まず以下の2つの準備が必要です。 Microsoft Office (Excel)のインストール Visual Studioから「参照の追加」=> 「COM」タブからMicrosoft Excel 11 Object Libraryを追加（COMのバージョン部分は、インストールしたOfficeのバージョンに依存します） サンプルコード 以下は、実際にExcelファイルを開いて、Cellへの読み書き、sheetの追加を行うサンプルコードです。 using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Office.Interop.Excel; namespace Example { class ExcelExample { private static void RunExcelExample() { Excel.Workbook book = null; Excel.Application excel = null; try { excel = new Excel.Application(); book = excel.Workbooks.Open(@"c:\test.xls", Type.Missing, true, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing,

I introduce some tips for reflection (not reflection of image but "programatic") of ActionScript 3.0. getDefinitionByName If you would like to Class object getDefinitionByName function should help. var c:Class = getDefinitionByName("flash.display.Sprite") as Class; If you would like to know details information of Class you can use describeType , which returns class information as Xml format. Reflective Class Instantiation import flash.utils.getDefinitionByName; public class Instantiator { private var classRef:Class; public function Instantiator(className:String) { this.classRef = getDefinitionByName(className) as Class; } public function newInstance(...args):Object { if(args.length == 0){ return new classRef(); } else { return new classRef(args); } } } Example usage: import flash.display.Sprite; import seedion.io.XMLExporter; // class will be instantiated at line with (*) import utils.tool.Instantiat
