I keep getting an error on all ap_whatever() functions, what am I forgetting here. Im running b+ v.1.45


Andres(Posted 1+ years ago)
Comment out: api_SetWindowPos(QueryObject(LoadingWindow, 1), -1, 0, 0, 0, 0, $0003)


Moore(Posted 1+ years ago)
Yeah the prob was that the api funtions are dependent of the user32.dll so I just had to include that and the user32.decls files in the user lib folder in blitz and poof it works. Thanks!


Petron(Posted 1+ years ago)
very cool, how do you set up a server?


Weetbix(Posted 1+ years ago)
Very cool


Andres(Posted 1+ years ago)
@Petron: As you know there's a server included in the archive. As the server type in the client: localhost:8088 or some else port you created the server.


Nike(Posted 1+ years ago)
I LOVE IT!!!


bLaU(Posted 1+ years ago)
is the user32.dll file the same one that's in window's system info? Also what does the user32.decls file need to have in it?


System4 Studios(Posted 1+ years ago)
Anyone got the source and media for this?


Andres(Posted 1+ years ago)
i do :P but i'm not home at the moment, i'll reupload them in few hours
