Open/Save File dialog at runtime

So i managed to get a Dialog working that gives me the path of the selected file.
Right now only for Windows.
I used the Code from the 2nd comment of Emiliarge from here

I needed to edit the included Files in the header.
i include:
#include “WindowsApplication.h”
#include “Windows/WindowsSystemIncludes.h”
#include “AllowWindowsPlatformTypes.h”
#include Commdlg.h

Iam not sure if this is a good and save way, or if i need to include other files…
But its working, as far as I could test it. Even after i made a shipping packed version.
I will keep you up to date if there are some problems that i missed…

I’m also loading 3D Models at runtime. Can i ask you, how your procedure for that import is?
