Use sun.misc Classes for Base64 Image Conversion

The following code demonstrates how to use sun.misc classes for Base64 image conversion: import*;import java.awt.*;import java.awt.event.*;class Base64Example extends Frame implements ActionListener{Image IMG=null; //image1Image IMGdecode=null; //image2-resultTextArea TA=new TextArea(); //printing the Base64 formButton B=new Button(“Decoder”);byte[] buffer_code=new byte[1024];byte[] buffer_decode;boolean bool=false;//constructorulpublic Base64Example(String titlu) { super(titlu); }void init() { Dimension dim=Toolkit.getDefaultToolkit().getScreenSize(); setSize(550,460); setLocation(dim.width/2-275,dim.height/2-280); setLayout(null);

Implement GetTickCount in Linux

How to Hide a ContextMenu

Streamline your Data Connections by Moving to MARS

ultiple Active Result Sets (MARS) is a new feature of ADO.NET 2.0 that allows multiple queries or stored procedures to be performed on a single connection. The result of this is that you can get and manage multiple, forward-only, read-only result sets on a single connection. Prior to MARS, each
