See the results(what matters is if you get the "Access 
Violation" error or not, everything else is irrelevant).

Fix your code first.

Your code is broken and in its current state fails to create 
window, hwnd = 0. GetLastError reports 1407 - 
ERROR_CANNOT_FIND_WND_CLASS.

First parameter for CreateWindow should be window class string 
that you used in

wndclass.lpszClassName = appName.toUTF16z;
