How do you set a cursor's position in a different window/application?

Question

I'm trying to set a cursor position to a specific set of coords in a different window, but the mouse never refreshes on that window unless I move the physical mouse I have.

This is for a program that moves the users cursor for them to a specific location IN A DIFFERENT WINDOW, and clicks after a logical expression returns true.

int x = 0;
int y = 0;
Cursor.Position = new Point(x, y);

I want the cursor to actually move inside of a window and not just in form1. The code will move the cursor to that position but it will not move on the window I am currently on.

Sending RAW Input data to use mouse. Some applications read raw mouse strokes while others read virtual mouse strokes.

int to_x = 500;
int to_y = 300;
int screenWidth = InternalGetSystemMetrics(0);
screenHeight = InternalGetSystemMetrics(1);
// Mickey X coordinate
int mic_x = (int)System.Math.Round(to_x * 65536.0 / screenWidth);
// Mickey Y coordinate
int mic_y = (int)System.Math.Round(to_y * 65536.0 / screenHeight);
// 0x0001 | 0x8000: Move + Absolute position
Mouse_Event(0x0001 | 0x8000, mic_x, mic_y, 0, 0);
// 0x0002: Left button down
Mouse_Event(0x0002, mic_x, mic_y, 0, 0);
// 0x0004: Left button up
Mouse_Event(0x0004, mic_x, mic_y, 0, 0);```
