I have tried the code that Marcos posted and it didn t worked for me  Whatever i was given to the Y coordinate the cursor didn t moved on Y axis  The code below will work if you want the position of the cursor relative to the left-up corner of your desktop  not relative to your application        DllImport  user32 dll   CharSet   CharSet Auto  CallingConvention   CallingConvention StdCall       public static extern void mouse event long dwFlags  long dx  long dy  long cButtons  long dwExtraInfo       private const int MOUSEEVENTF LEFTDOWN   0x02      private const int MOUSEEVENTF LEFTUP   0x04      private const int MOUSEEVENTF MOVE   0x0001       public void DoMouseClick                 X   Cursor Position X          Y   Cursor Position Y             move to coordinates         pt    Point pc ConvertFromString X         Y           Cursor Position   pt                    perform click                     mouse event MOUSEEVENTF LEFTDOWN  0  0  0  0           mouse event MOUSEEVENTF LEFTUP  0  0  0  0           I only use mouse event function to actually perform the click  You can give X and Y what coordinates you want  i used values from textbox               X   Convert ToInt32 tbX Text               Y   Convert ToInt32 tbY Text

I have combined several sources to produce the code below  which I am currently using  I have also removed the Windows Forms references so I can use it from console and WPF applications without additional references   using System  using System Runtime InteropServices   public class MouseOperations        Flags      public enum MouseEventFlags               LeftDown   0x00000002          LeftUp   0x00000004          MiddleDown   0x00000020          MiddleUp   0x00000040          Move   0x00000001          Absolute   0x00008000          RightDown   0x00000008          RightUp   0x00000010             DllImport  user32 dll   EntryPoint    SetCursorPos         return  MarshalAs UnmanagedType Bool       private static extern bool SetCursorPos int x  int y               DllImport  user32 dll         return  MarshalAs UnmanagedType Bool       private static extern bool GetCursorPos out MousePoint lpMousePoint         DllImport  user32 dll        private static extern void mouse event int dwFlags  int dx  int dy  int dwData  int dwExtraInfo        public static void SetCursorPosition int x  int y                 SetCursorPos x  y              public static void SetCursorPosition MousePoint point                SetCursorPos point X  point Y              public static MousePoint GetCursorPosition                 MousePoint currentMousePoint          var gotPoint   GetCursorPos out currentMousePoint           if   gotPoint    currentMousePoint   new MousePoint 0  0             return currentMousePoint             public static void MouseEvent MouseEventFlags value                MousePoint position   GetCursorPosition             mouse event               int value               position X               position Y               0               0                            StructLayout LayoutKind Sequential       public struct MousePoint               public int X          public int Y           public MousePoint int x  int y                        X   x              Y   y

I use the InvokeOnClick   method   It takes two arguments  Control and EventArgs   If you need the EventArgs  then create an instance of it and pass it in  else use InvokeOnClick controlToClick  null     You can use a variety of Mouse event related arguments that derive from EventArgs such as MouseEventArgs
