Nisam probao kod u asembleru ali na prvi pogled vidim da si ispred CreateWindowEx zaboravio prvi parametar (ExStyle). Zbog toga se rusi. Stavi Push 0 ispred Call CreateWindowEx
I jos jedna stvar kopiraj eax u hwnd posle CreateWindowEx mov hwnd,eax

Ovaj kod sam probao u MASM32 , imas komentare u kodu (sta je menjano)
Promeni samo includelib directive za svoj assembler u
includelib ..\lib\kernel32.lib
includelib ..\lib\user32.lib
Napravio si samo dve greske (ali kljucne)

Radi... fala puno, samo jos ovo da te pitam:
kako usporediti dva DWORDA

znaci ovo
cmp d1,d2
je nesto


a d1 je DWORD i d2 je DWORD i stalno mi javlja:
error A2070: invalid instruction operands
[ Eurora3D Team @ 05.01.2007. 19:46 ] @
Ne moze da poredi dve memoriske adrese
Uradi ovako:
;=======
mov eax,d2 ; kopiraj prvo sadrzaj u eax ili neki drugi registar
cmp d1,eax ; i onda ih uporedi
je nesto

Evo ti tabela uslovnih skokova iz Asemblerskog helpa
Jxx - Jump Instructions Table
Mnemonic Meaning Jump Condition
JA Jump if Above CF=0 and ZF=0
JAE Jump if Above or Equal CF=0
JB Jump if Below CF=1
JBE Jump if Below or Equal CF=1 or ZF=1
JC Jump if Carry CF=1

JCXZ Jump if CX Zero CX=0
JE Jump if Equal ZF=1
JG Jump if Greater (signed) ZF=0 and SF=OF
JGE Jump if Greater or Equal (signed) SF=OF
JL Jump if Less (signed) SF != OF
JLE Jump if Less or Equal (signed) ZF=1 or SF != OF
JMP Unconditional Jump unconditional

JNA Jump if Not Above CF=1 or ZF=1
JNAE Jump if Not Above or Equal CF=1
JNB Jump if Not Below CF=0
JNBE Jump if Not Below or Equal CF=0 and ZF=0
JNC Jump if Not Carry CF=0
JNE Jump if Not Equal ZF=0
JNG Jump if Not Greater (signed) ZF=1 or SF != OF

JNGE Jump if Not Greater or Equal (signed) SF != OF
JNL Jump if Not Less (signed) SF=OF
JNLE Jump if Not Less or Equal (signed) ZF=0 and SF=OF
JNO Jump if Not Overflow (signed) OF=0
JNP Jump if No Parity PF=0
JNS Jump if Not Signed (signed) SF=0
JNZ Jump if Not Zero ZF=0

JO Jump if Overflow (signed) OF=1
JP Jump if Parity PF=1
JPE Jump if Parity Even PF=1
JPO Jump if Parity Odd PF=0
JS Jump if Signed (signed) SF=1
JZ Jump if Zero ZF=1
Clocks Size
Operands 808x 286 386 486 Bytes

Jx: jump 16 7+m 7+m 3 2
no jump 4 3 3 1
Jx near-label - - 7+m 3 4
no jump - - 3 1
- It's a good programming practice to organize code so the
expected case is executed without a jump since the actual
jump takes longer to execute than falling through the test.

- see JCXZ and JMP for their respective timings

de_c0der postavio sam jedan primer za MASM na http://www.elitesecurity.org/t...rimer-unistavanja-procesa-MASM
Pogledaj kod. Imas neke osnovne manipulacije sa bajt nizovima (stringovima) i sl.
