start:
fn GetProcessHeap
mov HEAP, EAX
fn HeapAlloc, HEAP, 0, 1
mov EBX, EAX
mov AL, 5
mov [EBX], AL
fn GetStdHandle, STD_OUTPUT_HANDLE
mov TERM, EAX
fn WriteConsole, TERM, ADDR message, [EBX], ADDR by, 0
fn HeapFree, HEAP, 0, EBX
fn Sleep, 1000
fn ExitProcess, 0
end start
I run it and text "215" doesn't appear, just command prompt are printed again. GetLastError after WriteConsole return 8 as error code, that's defined as ERROR_NOT_ENOUGH_MEMORY, but i don't actually know, what it mean. Can anybody give me answer, where error is? Sorry for bad english.
You are passing a DWORD, pointed by ebx, to WriteConsole, but only one byte is allocated and filled.
