I'm trying to do a Simple Hello World app using C++ inline asm. something along these lines
#include <windows.h>
void main()
{
char* msg = "Hello World";
char* cap = "A Message";
// MessageBox(0,msg,cap,0); //This is what the asm should do
__asm
{
mov ebx, msg
mov ecx, cap
push 0
push ecx
push ebx
push 0
call MessageBoxA
}
}
I've tried all sorts of variations on this, but none of them seem to work.
I am getting a message box, but rather than saying "Hello World" it says "Unhandled excaption in Tests.exe: 0xC0000005: Access violation." I've stepped through the code and it raises it on the call MessageBoxA line, what am I doing wrong that causes the computer to make such a strange spelling mistake?
