Hi Friends,

         This is a small program named Xkeycode  that enables you to capture system screen. Once you run the code it will capture the screen and save  and png image in your system. so please try it out..

The above code have edited . you can use this code to take screen shot at intervals. intervals have choose as random. so one cant predict when the application will take screenshots. The screenshots will be saved in the folder named austincolle (In D drive)

Do you wish to sent the screenshot from your client machine to server? then see this java code
