Hallo,

kann auf Grundlage des unten aufgeführten Codes, mehr als eine Funktion
der win32api für Windows 64-Bit Systeme verwenden ?
Wenn ja, wie kann man den Code so erweitern ?

Bei dem vorliegenden Code handelt es sich um einen FLAT-Image Code, der
mittels:

nasm -f bin -o win.exe win.asm # oder:
yasm -f bin -o win.exe win.asm

zu einer .EXE assembliert werden kann.
Das heißt, es werden kein Linker oder andere Import-Bibliotheken zur
Erstellung benötigt.

Ich kann nichts zu 64 Bit Code sagen, da ich mir bisher
keinen Fall vorstellen kann bei dem es einen Vorteil
gegenüber 32 Bit Code gibt (bei kleinen Assemblerprogrammen).
Aber warum nutzt du die win32api für 64 Bit Windows Programme?

Hier ist das Grundgerüst das ich für 32 Bit Programm
verwende. Ich passe nur immer die Tabellen mit den
importierten Funktionen und den Assemblercode selbst an.
Der Aufbau ist sehr ähnlich deinem Code, vielleicht
hilft es dir ja weiter.

Hallo Herbert,

welchen Assembler nutzt Du?
sieht fast so aus, also wäre das für Ardunio...

Ich habe in der Zwischenzeit den Code abgeändert, aber da ist
noch irgendwo der Wurm drinn.
Möglicherweise ein Array-Problem.
Aber das konnte ich jetzt nicht hinbiegen, weil ich damit dann
voodoo Programming betreibe - was nicht sehr prikelnd sein kann.

Ich starte das Programm, aber die DLL scheint nicht geladen zu
werden, da sonst die MessageBoxA im DLL begin main Block aufpoppen
müsste ...

Ich habe zusätzlich eine DLL in FPC (Free Pascal Compiler) ge-
schrieben:

library kalle32;
uses windows;
procedure kalli(h: HWND; t,c: PChar; u: UINT); stdcall; export;
begin
MessageBoxA(h,t,c,u);
end;
begin
MessageBoxA(0,'xxxxx','tttt',0);
end.
