Try this code work for me :) For more info check out this reference link : http://www.pinvoke.net/default.aspx/user32.registerwindowmessage

using System.Runtime.InteropServices;

//provide a private internal message id
private UInt32 queryCancelAutoPlay = 0;

[DllImport("user32.dll", SetLastError=true, CharSet=CharSet.Auto)]
static extern uint RegisterWindowMessage(string lpString);

/* only needed if your application is using a dialog box and needs to 
* respond to a "QueryCancelAutoPlay" message, it cannot simply return TRUE or FALSE.
[DllImport("user32.dll")]
static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);
*/

protected override void WndProc(ref Message m)
{
    //calling the base first is important, otherwise the values you set later will be lost
    base.WndProc (ref m);

    //if the QueryCancelAutoPlay message id has not been registered...
    if (queryCancelAutoPlay == 0)
        queryCancelAutoPlay = RegisterWindowMessage("QueryCancelAutoPlay");

    //if the window message id equals the QueryCancelAutoPlay message id
    if ((UInt32)m.Msg == queryCancelAutoPlay)
    {
        /* only needed if your application is using a dialog box and needs to
        * respond to a "QueryCancelAutoPlay" message, it cannot simply return TRUE or FALSE.
        SetWindowLong(this.Handle, 0, 1);
        */
        m.Result = (IntPtr)1;
    }
} //WndProc
