How I can send mouse click in powershell?

Question

How I can send mouse click on this position with this code. I want my mouse to go there and click.

[System.Windows.Forms.Cursor]::Position = New-Object System.Drawing.Point($xposi,$yposi)

If you don't feel like writing your own function, the Windows Automation Snapin for Powershell has a Send-Click function. Alternatively you can import some functionality from the windows API using mouse_event although I would recommend SendInput as it supersedes mouse_event. Below is a fully functional sample that uses P/Invoke to get the functionality you want and send a left click to a specified screen coordinate.

$cSource = @'
using System;
using System.Drawing;
using System.Runtime.InteropServices;
using System.Windows.Forms;
public class Clicker
{
//https://msdn.microsoft.com/en-us/library/windows/desktop/ms646270(v=vs.85).aspx
[StructLayout(LayoutKind.Sequential)]
struct INPUT
{ 
    public int        type; // 0 = INPUT_MOUSE,
                            // 1 = INPUT_KEYBOARD
                            // 2 = INPUT_HARDWARE
    public MOUSEINPUT mi;
}

//https://msdn.microsoft.com/en-us/library/windows/desktop/ms646273(v=vs.85).aspx
[StructLayout(LayoutKind.Sequential)]
struct MOUSEINPUT
{
    public int    dx ;
    public int    dy ;
    public int    mouseData ;
    public int    dwFlags;
    public int    time;
    public IntPtr dwExtraInfo;
}

//This covers most use cases although complex mice may have additional buttons
//There are additional constants you can use for those cases, see the msdn page
const int MOUSEEVENTF_MOVED      = 0x0001 ;
const int MOUSEEVENTF_LEFTDOWN   = 0x0002 ;
const int MOUSEEVENTF_LEFTUP     = 0x0004 ;
const int MOUSEEVENTF_RIGHTDOWN  = 0x0008 ;
const int MOUSEEVENTF_RIGHTUP    = 0x0010 ;
const int MOUSEEVENTF_MIDDLEDOWN = 0x0020 ;
const int MOUSEEVENTF_MIDDLEUP   = 0x0040 ;
const int MOUSEEVENTF_WHEEL      = 0x0080 ;
const int MOUSEEVENTF_XDOWN      = 0x0100 ;
const int MOUSEEVENTF_XUP        = 0x0200 ;
const int MOUSEEVENTF_ABSOLUTE   = 0x8000 ;

const int screen_length = 0x10000 ;

//https://msdn.microsoft.com/en-us/library/windows/desktop/ms646310(v=vs.85).aspx
[System.Runtime.InteropServices.DllImport("user32.dll")]
extern static uint SendInput(uint nInputs, INPUT[] pInputs, int cbSize);

public static void LeftClickAtPoint(int x, int y)
{
    //Move the mouse
    INPUT[] input = new INPUT[3];
    input[0].mi.dx = x*(65535/System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width);
    input[0].mi.dy = y*(65535/System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height);
    input[0].mi.dwFlags = MOUSEEVENTF_MOVED | MOUSEEVENTF_ABSOLUTE;
    //Left mouse button down
    input[1].mi.dwFlags = MOUSEEVENTF_LEFTDOWN;
    //Left mouse button up
    input[2].mi.dwFlags = MOUSEEVENTF_LEFTUP;
    SendInput(3, input, Marshal.SizeOf(input[0]));
}
}
'@
Add-Type -TypeDefinition $cSource -ReferencedAssemblies System.Windows.Forms,System.Drawing
#Send a click at a specified point
[Clicker]::LeftClickAtPoint(600,600)

Solution 2

Here is the older method:

#import mouse_event
Add-Type -MemberDefinition '[DllImport("user32.dll")] public static extern void mouse_event(int flags, int dx, int dy, int cButtons, int info);' -Name U32 -Namespace W;
#left mouse click
[W.U32]::mouse_event(6,0,0,0,0);

6 is 0x02 | 0x04, LMBDown | LMBUp from the documentation

https://msdn.microsoft.com/en-us/library/windows/desktop/ms646260(v=vs.85).aspx

And here is moving and clicking

#move 10% along x and 10% along y and send left mouse click
[W.U32]::mouse_event(0x02 -bor 0x04 -bor 0x8000 -bor 0x01, .1*65535, .1 *65535, 0, 0);
