Code By : Tapas jena
My Email:tapas.friends@gmail.com
Updated Date : january , 2010
================== Directory ====================================================
step 1 : make directory james in c: , that is c:\james
step 2 : place the following files in this directory
a. addrec.java d.Andrew.jpg g.Laura.jpg j.Nancy.jpg
b. james.mdb e.James.jpg h.Margaret.jpg k.Robert.jpg
c. sidebar33.jpg f.Janet.jpg i.Micheal.jpg l.Steven.jpg
download these files from
http://www.geocities.com/james_smith73
Download Menu --> james.zip
================== c:\Autoexec.bat ==================================================
(assumption u have installed jdk in c:\jdk1.2.1 directory , works in higher versions too )
(add below lines in c:\Autoexec.bat - Restart your Computer for Settings to take effect)
(If Nesssary)
step 3 : SET classpath= (NOTE :: To be done only incase there is any problem running the application)
step 4 : SET PATH=c:\windows;c:\windows\command;c:\jdk1.2.1\bin;c:\
step 5 : SET JAVA_HOME=c:\jdk1.2.1
================== ODBC Settings ========================
step 6 : click control panel
step 7 : ODBC Data Sources
step 8 : click UserDSN Tab
step 9 : click ADD Button , Select Microsoft Access Driver , Finish
step 10 : Give Datasource Name as "james" , no double quotes
step 11 : use Select and select james.mdb from c:\james\james.mdb
click ok , ok finish
================== Compile =======================================================
step 12 : cd c:\james
step 13 : javac addrec.java
================= Run ============================================================
step 14 : java addrec
(IF U GET CLASSNOT FOUND ERROR : set classpath= will help u overcome this)
login 'a' and password 'a' for Accoutant (use this)
login 'p' and password 'p' for Principal
================================================================================
I prefer u reading this on Macromedia Homesite Editor 5.0 to Edit my java code
u may as well crack it friends , keep it a secret :) hahahahaha...... ,
