鼠标单击并拖动不起作用

Question

I have a external window I am sending a mouse click and drag to. For some reason it isn't dragging it. Any help is much appreciated.

        public void clickAndDrag(Point pointA, Point pointB)
    {
        Point tmp = Cursor.Position;

        mouse_event((int)(MouseEventFlags.LEFTUP), 0, 0, 0, 0);
        Cursor.Position = ConvertToScreenPixel(pointA);
        System.Threading.Thread.Sleep(1000);
        mouse_event((int)(MouseEventFlags.LEFTDOWN), 0, 0, 0, 0);
        Cursor.Position = ConvertToScreenPixel(pointB);
        System.Threading.Thread.Sleep(1000);
        mouse_event((int)(MouseEventFlags.LEFTUP), 0, 0, 0, 0);


        Cursor.Position = tmp;
    }

I figured it out. You need to slowly move the mouse I guess. But this worked to click and drag to the left a bit. It is total garbage but I am too tired to try to refactor it.

        public void clickAndDrag(Point pointA)
    {
        Point tmp = Cursor.Position;
        pointA.X = pointA.X + 20;
        pointA.Y = pointA.Y + 20;

        mouse_event((int)(MouseEventFlags.LEFTUP), 0, 0, 0, 0);
        Cursor.Position = ConvertToScreenPixel(pointA);
        System.Threading.Thread.Sleep(1000);
        mouse_event((int)(MouseEventFlags.LEFTDOWN), 0, 0, 0, 0);

        for (var i = 0; i < 10; i++)
        {
            pointA.X = pointA.X - 10;
            Cursor.Position = ConvertToScreenPixel(pointA);
            System.Threading.Thread.Sleep(200);
            mouse_event((int)(MouseEventFlags.MOVE), 0, 0, 0, 0);
        }


        mouse_event((int)(MouseEventFlags.LEFTUP), 0, 0, 0, 0);


        Cursor.Position = tmp;
    }
