Click on button in another program - FindWindow, C#

Question

I\'m trying to create a program that will be able to control another program (in Windows).

I found this code:

// Get a handle to an application window.
[

You can use the following code to simulate mouse click:

        [System.Runtime.InteropServices.DllImport("user32.dll")]
        static extern bool SetCursorPos(int x, int y);

        [System.Runtime.InteropServices.DllImport("user32.dll")]
        public static extern void mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo);

        public const int MOUSE_LEFTDOWN = 0x02;
        public const int MOUSE_LEFTUP = 0x04;

        public static void LeftMouseClick(int x, int y)
        {
            SetCursorPos(x, y);
            mouse_event(MOUSE_LEFTDOWN, x, y, 0, 0);
            mouse_event(MOUSE_LEFTUP, x, y, 0, 0);
        }

Method LeftMouseClick is getting two parameters x and y representing coordinates on user screen:

LeftMouseClick(400, 200);

Or you can do it by keyboard: Link

private void button2_Click(object sender, EventArgs e)
    {          
       SendKeys.Send("{ENTER}");
    } 

basically that's what you are doing in your code:

SendKeys.SendWait("111");
SendKeys.SendWait("*");
SendKeys.SendWait("11");
SendKeys.SendWait("=");

I dont think there is another way of doing this.
