Question

If I know an X and Y coordinate, is there a Windows API or some technique in .Net that I can use to cause the mouse pointer to move to that point?

I know there must be something because there are tools that seem to jump the mouse. But I don’t know if those APIs are easily accessible in .Net. Is there?

Please assume WPF, .Net, and Windows (of course).

Solution

public Window1()  
{  
    InitializeComponent();  
    NativeMethods.SetCursorPos(300, 300);  
}  
public partial class NativeMethods  
{  
    [System.Runtime.InteropServices.DllImportAttribute("user32.dll", 
        EntryPoint = "SetCursorPos")]  
    [return: System.Runtime.InteropServices.MarshalAsAttribute
        (System.Runtime.InteropServices.UnmanagedType.Bool)]  
    public static extern bool SetCursorPos(int X, int Y);  
} 

Answer 1

Declare import like this:

[DllImport("user32.dll")]
static extern bool SetCursorPos(int X, int Y);

And use like this:

SetCursorPos(x, y);
