Autoit SDL2 DLL Help

[TheXman]

You're welcome.

As you can see in my sdl2.au3, the dllopen() is not necessary.  You can just point the dllcall() to the correct dll file.

Yeah.  Ok I need a little help getting this example to work. I am getting this error  C:\Program Files (x86)\AutoIt3\SciTE\..\autoit3.exe" /ErrorStdOut "C:\Users\username\Documents\Code\AuotIt\SDLTest2.au3"    
>Exit code: 3221225477

The window appears, but then comes up with the exit code and the windows failed to close this program properly pops up.
