I wrote something like that , it changes display picture after a few seconds..

function OnEvent_Signin(mail)
{
    var Message = "Your picture will be changed!";
    MsgPlus.DisplayToast("",Message);
    MsgPlus.AddTimer("resim",50000);
}

function OnEvent_Timer(timerid)
{
    if(timerid=="resim")
    {
        Messenger.MyDisplayPicture="C:/dsc.jpeg";
    }
}


but it gives error ;


Function called: OnEvent_Signin
Function called: OnEvent_Timer
Error: Geçersiz yordam çağrısı veya değişken. (something like unaccepted variable or function in english)
       Line: 12. Code: -2146828283.
