Hi bgcq,

Sorry for the delayed response, and I hope you don't mind me

I'm not much of a Windows programmer. I can do:

;-------------------
; assemble: nasm -f obj hwmb.asm
; link: alink -oPE hwmb.obj win32.lib

extern MessageBoxA
extern ExitProcess

segment .data USE32
     title1    db 'A Windows Program', 0
     string1   db 'Look, Ma! A Windows program!', 0

segment .text USE32

..start
     push dword 0Ch       ; button type - supposed to be 0,
     push dword title1    ; but I need all the help I can get :)
     push dword string1
     push dword 0         ; our "handle", I think
     call MessageBoxA

     push dword 0
     call ExitProcess
;--------------------

... but I don't know if that really qualifies as a "gui Windows app", 
since we haven't created a window. For a "real" Windows program, you'd 
first register a window class, then create your window, then pretty much 
sit in a loop fielding messages. I *do* have a few examples of that, but 
not really cleaned up enough to post.

One of the best sources of examples might be to download NaGoA - 
http://www.visual-assembler.pt.vu/ - whether you use the IDE or not, 
there are a *ton* of examples included with it.

You might also want to take a look at Sheroc's complete package based on 
Jibz's Xstruc macros. I think it's only got one example with it...

http://www.freewebs.com/remains/NASM32PACKAGE.exe

I'll try to come up with a "minimal real window" example. Maybe someone 
else has got one? Well, only a few subscribers to the list, as yet... 
maybe in a while when we get some subscribers, someone will have one :)

Please do subscribe to that list (if you're inclined), and we'll see if 
we can get some discussion going.

Best,
Frank
