InpOut32.dll

branleb

ich benutz die Inpout32.dll um den LPT1
anzusprechen allerdings is da ein bug...
jedes mal wenn ich out32/inp32 nutz kackt mein prog wegen einer acces violation at 0x0000000000 ab.
ich hab die functions mit getprocaddress() importiert und wool grafgen uo mir jemand helfen kann.....

Okay.

branleb

compiler is egal ich hab versucht bcc32, cl und watcom keiner hab gefunzt...

Code?

das wrs....

Zuviel unnötiger Code.

schau mal wann du init aufrufst und die "library" initialisierst

ansonsten solltest du bitte immer minimale Code Beispiele posten. Lies am besten mal wmfrs Wenn du dich an die Regeln hälst, bekommst du idr. schnell kompetente Antworten, aber die Sachen ergeben sich eigentlich wenn man über seine Posts mal nachdenkt
