Question

This is my code that throws an exception, it just randomly started today here is the photo :

Here is the whole page code and the error exception :

 public frmWFDocumentDetail()
    {
        InitializeComponent();

        NavigationInTransition navigateInTransition = new NavigationInTransition();
        navigateInTransition.Backward = new TurnstileTransition { Mode = TurnstileTransitionMode.BackwardIn };
        navigateInTransition.Forward = new TurnstileTransition { Mode = TurnstileTransitionMode.ForwardIn };

        NavigationOutTransition navigateOutTransition = new NavigationOutTransition();
        navigateOutTransition.Backward = new TurnstileTransition { Mode = TurnstileTransitionMode.BackwardOut };
        navigateOutTransition.Forward = new TurnstileTransition { Mode = TurnstileTransitionMode.ForwardOut };
        TransitionService.SetNavigationInTransition(this, navigateInTransition);
        TransitionService.SetNavigationOutTransition(this, navigateOutTransition);

        DataContext = App.ViewModel_WFDocumentDetailItems;
    }

    protected override void OnNavigatedTo(NavigationEventArgs e)
    {
        //**this is how you pass parameters through to a new page**//
        string processID = "-1";
        string processName = "";
        NavigationContext.QueryString.TryGetValue("processID", out processID);
        NavigationContext.QueryString.TryGetValue("processName", out processName);

        App.ViewModel_WFDocumentHeaderItems.LoadData("johnny", processID);

        App.ViewModel_WFDocumentDetailItems.LoadData("johnny");

    }

and the access violation :

System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory
is corrupt.

I have read up on it, some people say it is nvidia network manager, and some people say I must set some setting like Suppress JIT optimization , and ignore gpu memory if value isn’t changed… but nothing works? Can anyone please please send me in the right direction?

As requested , the full stack

Answer 1

i used the setting taylorjohnl gave me “Debug -> Options and Settings -> Debugging -> General -> Enable Just My Code”,and then the error went right to the piece of xaml that was a syntax error, and boom fixed it and app works again 🙂 so violation error for me was basically a reference error, hope this can help other people as well, also use expression blend in silverlight to debug xaml in the UI
