Introduction

using your webcam for slideshow presentation, you can slide forward and backward using laser gesture, by moving it from left to right or vice versa.

Codesnipt:

// Code for controlling PowerPoint SlideShow
        private void ControlPowerPoint(string gesture)
        {
            IntPtr powerPointHandle = FindWindow(null, "PowerPoint Slide Show - ["+slideName+"]");
            
            // Verify that PPS is a running process.
            if (powerPointHandle == IntPtr.Zero)
            {
                System.Windows.Forms.MessageBox.Show("Slide Show not running");
                return;
            }
            switch (gesture)
            {
                case "LEFT":
                    SetForegroundWindow(powerPointHandle);
                    SendKeys.SendWait("p");
                    Beeper.RecognizedBeep();
                    break;
                case "RIGHT":
                    SetForegroundWindow(powerPointHandle);
                    SendKeys.SendWait("n");
                    Beeper.RecognizedBeep();
                    break;
                case "DIAGONAL2B":
                    SetForegroundWindow(powerPointHandle);
                    SendKeys.SendWait("n");
                    Beeper.RecognizedBeep();
                    break;
                case "DIAGONAL1A":
                    SetForegroundWindow(powerPointHandle);
                    SendKeys.SendWait("n");
                    Beeper.RecognizedBeep();
                    break;
                case "DIAGONAL1B":
                    SetForegroundWindow(powerPointHandle);
                    SendKeys.SendWait("P");
                    Beeper.RecognizedBeep();
                    break;
                case "DIAGONAL2A":
                    SetForegroundWindow(powerPointHandle);
                    SendKeys.SendWait("P");
                    Beeper.RecognizedBeep();
                    break;
                case "UP":
                    SetForegroundWindow(powerPointHandle);
                    SendKeys.SendWait("n");
                    Beeper.RecognizedBeep();
                    break;
                case "DOWN":
                    SetForegroundWindow(powerPointHandle);
                    SendKeys.SendWait("p");
                    Beeper.RecognizedBeep();
                    break;
            }
        } 

its really fun that you can talk to the windows applications and command them with your application whatever was the method to do that but i like it ..
