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 .
