c++/cli best way to retrieve wpf window result

Question

I have a WPF window and I'm calling it from a C++/cli code and it works fine. What I need is what's the best way to intercept user action I mean whether he click OK or Cancel. Wath I think to do is to define a Boolean property in my window and set it depends on user action. Here is my code :

MyWindowView^ window = gcnew MyWindowView();
System::Windows::Interop::WindowInteropHelper^ windowInteropHelper = gcnew System::Windows::Interop::WindowInteropHelper(window);
windowInteropHelper->Owner = (IntPtr)AfxGetMainWnd()->m_hWnd;
window->WindowStartupLocation = System::Windows::WindowStartupLocation::CenterScreen;
window->ShowDialog();
if ()
{
    //some action
} 
else
{
    //
}

Also I want to know do I need to delete the window object ?

Window.ShowDialog returns dialog result. I can't see any reason to get this result in some way, that differs from C# or VB .NET:

System::Nullable<System::Boolean> result = window->ShowDialog();
if (result.HasValue)
{
    // OK or Cancel
    if (result.Value)
    {
        // OK clicked
    }
    else
    {
        // Cancel clicked
    }
}
else
{
    // dialog closed via system menu or Alt+F4
}

do I need to delete the window object ?

No, you don't. See this answer.

Hi Dennis actually for the Ok and Cancel buttons are custom not the defined ones for dialog result so do you think that ShowDialog can get the result of that buttons – MRebai Dec 01 '15 at 08:33

@MoezRebai: what do you mean by "custom buttons"? Anyway, if your buttons will set `Window.DialogResult` property, you'll get a proper return value. – Dennis Dec 01 '15 at 08:34
