ASM Community

I could be more modest, yes, but then you'd think I just acquired my first computer last week.


Knowing C++ has sod all to do with knowing anything about programming, or assembly, or indeed the computer. C++ is IMHO, over-rated.

I know about those parts of Windows I've dealt with in the past, and I'm researching the bits I don't.

I have already written a working GINA stub. According to the MS docs this is an "advanced" topic. I may not be able to rattle off everything from memory straight away, but it doesn't make my code any less reliable or efficient. Clearly I must know *something* to do even this!!!

I can't stress enough that I research, research, then research some more. If you can't handle my rate of progress, what am I supposed to do about it?

...and just in case you think that was a quick edit in MS Paint (this code had the MessageBox stripped out - it was located in DLL_PROCESS_ATTACH):

.data?
hThisDLL dd ?
hDLL dd ?
func dd ?
hGINA dd ?
pWinLF dd ?

.code
DLL db "msgina.dll",0
f1 db "WlxInitialize",0
app db "Test GINA",0
msg db "If you're reading this, it worked!",0

DllEntry proc hInstDLL:DWORD, reason:DWORD, reserved1:DWORD
	cmp reason,1
	jnz DLL_DETATCH

	pushad

	mov eax,hInstDLL
	mov hThisDLL,eax
	push hThisDLL
	call DisableThreadLibraryCalls

	push offset DLL
	call LoadLibrary
	mov hDLL,eax

	popad

        mov eax,1h
	ret 0Ch

DLL_DETATCH:
	cmp reason,0
	jnz FAIL

	pushad

	push hDLL
	call FreeLibrary

	popad

	mov eax,1h

WlxInitialize proc lpWinsta:DWORD, hWlx:DWORD, pvReserved:DWORD, pWinlogonFunctions:DWORD, pWlxContext:DWORD
	pushad

WlxInitialize endp

You think I'm going to give away all my hard work? I know - a bit mean, but it seems this thread is degrading into a flame-war. Please note the code is still in development.

It's simple - you say I can't do this quickly and be any good - I'm showing you I CAN.

I may ask basic questions on some subjects, but it is to ensure I'm doing things correctly. The fact I'm doing that on the back of a complex project is irrelevent. At the end of the day - either the code works or it doesn't - that's easy. I'm interested in doing it *right*, and ensuring I understand every line of code written.

Thanks Bruce - appreciate it.

Best regards,
Astro.
