Tips & Tricks:

Please add some!

Sample Code:

[DllImport("user32.dll")]
static extern bool SetCursorPos(int X, int Y);  

[DllImport("user32.dll")]
static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint dwData,  int dwExtraInfo);

[Flags]
  public enum MouseEventFlags
  {
    LEFTDOWN   = 0x00000002,
    LEFTUP     = 0x00000004,
    MIDDLEDOWN = 0x00000020,

...
//Set cursor position  
SetCursorPos(10, 50);
//Mouse Right Down and Mouse Right Up
mouse_event((uint)MouseEventFlags.RIGHTDOWN,0,0,0,0);
mouse_event((uint)MouseEventFlags.RIGHTUP,0,0,0,0);
