Report to Server Using RMI

This RMI Program to report The content in remote Server.This Code will use to for report your Server.Remote method invocation is best one in Java.In below example code this technique will use.please usea as following steps to run this program.

Steps:

1) create serializale Interface DataBaseAccessMethods
2) create DataBaseAction
3) create ReportServer(Rmi Server)
4) create ReportUser(Client)
5) run commandpromt  rmic DataBaseAction
6) run rmiregistry with port
7) run RmiServer(ReportServer)
8) run Rmiclient(ReportUser)

JavaScript Blendering Effect

Blend Filter:

Here We write the Html Examples for Blundering effect. This Blundering effects most use for Web designing .Blundering effects are mostly use in web pages opening and closing times.here we give the sample of code and example.you copy this code and run it .you get the result of Blundering.you also run our  example.Thank you.

Below code used for Blundering Effect..


<br /> <head><br /> <script> function fadeOut() { oDiv.style.filter="blendTrans(duration=2)"; if (oDiv.filters.blendTrans.status != 2) { oDiv.filters.blendTrans.apply(); oDiv.style.visibility="hidden"; oDiv.filters.blendTrans.play(); } } function fadeIn() { oDiv.style.filter="blendTrans(duration=2)"; if (oDiv.filters.blendTrans.status != 2) { oDiv.filters.blendTrans.apply(); oDiv.style.visibility="visible"; oDiv.filters.blendTrans.play(); } } </SCRIPT><br /> <br /> Blend Filter:<br /> <br /> <br /> <img src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh3MkmvojAXfKiuGYwD6TwpreES2-BeLid7zf_jAS5UU6vq6lNvpj2ZYktvVkR57ZPRufRkgBc9_T4YEln15YAMEDS18nNu4bJTX-rS80jvKElGTv4RkVbEzxRt9aPsDYjyPbEhsEhdUSEm/s320/contact3.jpg" width='200' height='200' ID="oDiv" /><br /> <p><button onclick="fadeOut()">Fade Image Out</BUTTON> <br /> <button onclick="fadeIn()">Fade Image In</BUTTON><br /> </P>

Java Remote Desktop Monitoring

Following Code used to Remote Desktop Monitoring....

This following code to capture the client Screen and send it to the server.Server to Record the Screen on hard disk .This program to implement the Server socket concept.This code is very good one.here not implement Multi-threading.you have used to multi threading and captures all you client screen

ImageCapture.java

1.This code client side code

2. This code Capture the current window screen and sends to particular server system .
