Question

I can’t get it to sleep, I want it to pause for a second before continuing.

public static void main(String[] args) {  
        //supply your own path instead of using this one 
        String path = "\\image.JPG";  
        for(;;)
            SPI.INSTANCE.SystemParametersInfo(     
                new UINT_PTR(SPI.SPI_SETDESKWALLPAPER),    
                new UINT_PTR(0),      
                path,          
                new UINT_PTR(SPI.SPIF_UPDATEINIFILE | SPI.SPIF_SENDWININICHANGE));
        }

When i try to add Thread.sleep(1000); it gives me an error, unreachable code.

Try this… adding the sleep method inside the for loop.

public static void main(String[] args) {  
        //supply your own path instead of using this one 
        String path = "\\image.JPG"; 

        for(;;){

                try{
                    Thread.sleep(1000);
                    SPI.INSTANCE.SystemParametersInfo(     
                    new UINT_PTR(SPI.SPI_SETDESKWALLPAPER),    
                    new UINT_PTR(0),      
                    path,          
                    new UINT_PTR(SPI.SPIF_UPDATEINIFILE | SPI.SPIF_SENDWININICHANGE));
                    }catch(Exception ex){

                    }


          }
