Getting started

Code Select Expand

include \masm32\include\masm32rt.inc

.code
AppName db "Masm32:", 0

start: MsgBox 0, "Hello World", addr AppName, MB_OK
exit

end start


I've also tried :

Code Select Expand

include \masm32\include\masm32rt.inc

.code
AppName db "Masm32:", 0

start:
mov eax,9h
mov ebx,9h
add eax,ebx
MsgBox 0, eax, addr AppName, MB_OK
exit

end start


trying to find out how to show the result in the message box can anyone walk me through it ?

I forgot about this site:

[qWord]

MsgBox 0, str$(eax), addr AppName, MB_OK

see now I love it as I now can figure things out faster thank you all I'll see what I can do for now

[roddym]

is there a list I'm not seeing that list how to get things like menus etc ?

Code Select Expand

include \masm32\include\masm32rt.inc

.code
AppName db "Masm32:", 0
AppName2 db "Masm33:", 0
AppName3 db "Masm34:", 0

start:
mov eax,1h
MsgBox 0, str$(eax), addr AppName, MB_OK
add eax,eax
inc eax
MsgBox 0, str$(eax), addr AppName2, MB_OK
add eax,eax
inc eax
MsgBox 0, str$(eax), addr AppName3, MB_OK
exit

end start

It works for the first 2 but the third only changes the title the number should change but it doesn't it's the mersenne sequence if you'd like to know so 1,3,7, right now it's going 1 3 & 3

[qWord]

eax,edx and ecx can be used by API-call without saving them. Edi, esi and ebx are preserved (inside API-callback you must preserve them if used). Also eax is used as return value for functions, so that its content allways change. This is called WinABI - Windows Application Binary Interface.
You must save EAX (e.g. on stack), because it is changed by MessageBox.
