    }


    private void SimulateLeftClick()
    {
        int xpos = Cursor.Position.X;
        int ypos = Cursor.Position.Y;
        mouse_event(MOUSEEVENTF_LEFTDOWN, xpos, ypos, 0, 0);
        mouse_event(MOUSEEVENTF_LEFTUP, xpos, ypos, 0, 0);
    }
case "left click":
                int xpos = Cursor.Position.X;
                int ypos = Cursor.Position.Y;
                mouse_event(MOUSEEVENTF_LEFTDOWN, xpos, ypos, 0, 0);
                mouse_event(MOUSEEVENTF_LEFTUP, xpos, ypos, 0, 0);
                break;

   private void Form1_Click(object sender, EventArgs e)
    {

        MessageBox.Show("Left Click simulated");
    }

when i run this program an error gives "Top-level control cannot be added to a control." at the this.Controls.Add(Form1) in above program. so please anyone give me a solution

Answer 1

The top-level control is defined as the parent control that is not parented by another Windows Forms control. Typically, this is the outermost Form that the control is contained in.

In your case, it seems Form1 is the top level control. Remove the line:

 this.Controls.Add(Form1);
