simulate mouse movements and click operations in c#

[madhuri.eerupula]

Hi.
How to simulate(automatic) mouse movements and click operation using c#.
Actually, i got pixels in the face (face tracking) right now and i need to move mouse(automatically, without using mouse manually) i.e., simulate mouse click operation using those pixels in c#.
I think we can use robot() class in java , to achieve this, but how can we do this using c#.
Hope you understand my problem and get bck to me asap.


thanx
bye

Hai friend,
use the code below to simulate mouse click

using System.Runtime.InteropServices;
 
private const UInt32 MOUSEEVENTF_LEFTDOWN = 0x0002;
private const UInt32 MOUSEEVENTF_LEFTUP = 0x0004;
[DllImport("user32.dll")]
        private static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint dwData, uint dwExtraInf);
private void btnSet_Click(object sender, EventArgs e)
        {
            int x = Convert.ToInt16(txtX.Text);//set x position 
            int y = Convert.ToInt16(txtY.Text);//set y position 
            Cursor.Position = new Point(x, y);
            mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);//make left button down
            mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);//make left button up
        }
 

txtX is a text box to set x position of cursor
txtY is a text box to set y position of cursor
btnSet is a a button
when yo clicks on the button btnset the cursor will move to the position specified in two text boxes(txtX & txtY)
