ASM Community

Hi!
In the past, I used MASM, but when I tried several compilers (C,C++,ASM,VB,Python,etc), I found that FASM fits best my programming needs, because it's simple, fast, and flat :-)
Now I'm trying to step to next level (I coded only msgboxes and some other dummy little nothing).
With hard guesses through days I found how to code in macro mode :-)
Now I want a little text mode splash screen: only a plain little topmost window without caption and some text in it.
I read a few win32asm tutorials, ckecked a lot of asm sample code (MASM :( ), but after a few wasted days with a lot of tries I'm now confused, because my asm code goes worse and worse... PLEASE HELP ME. Here is the source:

include '%include%\win32ax.inc'

_brsh dd 0

_wtx dd 0

_wty dd 0

_hDC dd 0

_paintstruct PAINTSTRUCT

_rect RECT

Hi MACi,

CreateWindowEx needs RegisterClassEx. And,

sizeof.WNDCLASSEX

and beside,

.code

use this one,

section '.code' code readable executable

also you need a message loop,

msg_loop:
invoke GetMessage,msg,NULL,0,0
or eax,eax
jz end_loop
invoke TranslateMessage,msg
invoke DispatchMessage,msg
jmp msg_loop
end_loop:
invoke ExitProcess,

after this line,

invoke UpdateWindow,[_mainhwnd]

as I saw yet. And look at examples, documents, which comes with your zip package(fasmw.zip). Also here there are more examples about translation of iczelion tuts. Like
this link

Regards

yes but except don't need small icon. In this case WNDCLASS is OK.

Sorry guys, but these infos are mostly useless, anyway thanks for your help.

I wrote before this:
"I changed the

to
invoke RegisterClassEx,wc
now don't crashes, but doesn't shows up anything"

I wrote before this:
"I found how to code in macro mode"
so I want to use macro mode furthermore, this means:
.data
.code
etc.
Did you see the include file at the beginning? include '%include%\win32ax.inc'
This allows macro mode, and I added an .rsrc macro to this include file also.

Do you think I need that message loop when I want only a splashscreen?
I tried few days ago to compile with those kind of message loop, but then I have to kill manually the window (living only in memory and it didn't had a visible window!), before the prg steps to the Sleep code.

You wrote:
"If you used WNDCLASSEX, also i assume you have,
import user,RegisterClassEx,'RegisterClassExA',CreateWindowEx,'CreateWindowExA' "...
I used include '%include%\win32ax.inc' that includes '%include%/apia/user32.inc'

Anyway, thanks for the dot :) in sizeof.WNDCLASSEX, it works.
...but I don't get yet any window :(

RegisterClass requires WNDCLASS structure.
RegisterClassEx requires WNDCLASSEX structure.
CreateWindowEx doesn't care about WNDCLASS or WNDCLASSEX.

I digged thorough the FASM forum, and I saw many people have problems like I had when I started with FASM in the past.
I think these problems are not about asm tutorials, but about FASM SYNTAX!!!
Like I had that kind of problem nowadays with sizeof operand:
TASM (perhaps MASM syntax)
sizeof WNDCLASSEX
in FASM:
sizeof.WNDCLASSEX
When I don't know about that little dot, I cannot compile my code, so I cannot do my next step.
So people want FASM syntax tutorial!
(I've been searching for it, but nothing found)
