hi,
i dont know, why my pc tells me that the operand size(!translationPROBLEM)is not the same.
If noone can help me or dont want to, then youve got a tutorURL maybe.

thx anyway

Hiya,
Tried to send you a pm but it says I'm not logged in so I have sent an email, (maybe) .

Hi,

try to declare the variations as Cardinal (or LongInt) and not as Variant.

Btw. I think, that the code is so easy that you don't need to use asm:

EAX := 2;
EBX := 6;
EAX := EAX + EBX;
Final := EAX;
Edit3.Text := IntToStr(Final);

or

EAX := 2;
EBX := 6;
EBX := EBX + EAX;
Final := EBX;
Edit3.Text := IntToStr(Final);

or in ASM

asm
mov eax, 2
mov ebx, 6
add ebx, eax
mov Final, ebx
end;
Edit3.Text := IntToStr(Final);

(btw. in your example the value in Final will be '6' (as it is the value that is moved from EBX) because you typed add eax, ebx. If you want to add eax to ebx you must type add ebx, eax. Then the value in Final will be '8'.

hi, 1st thx for ur reply but i know that i can add 6 and 2 in another way. But i want to use asm in 32bit, else i have to prog an exclusiveOr or a shiftLeft function to use them in VB. And win32asm isnt an option 4 me, cause im very lazy. I just have some problems to understand pascalsyntax and the compiler-messages. what means "Operamds size isnt the same"@mov Final, ebx.

Hi,

what version of compiler do you use? Have you tried to look into Help? I've found this (I think this can be the solution):

=============== Paste from Help ===============
Error: Operand size mismatch

Description

The size required by the instruction operand does not match the size given.

In the sample above, the compiler will complain because the 'offset' operator produces a 'dword', but the operator is expecting a 'byte'.

program Produce;

var
v : Integer;

procedure Assembly;
asm
db offset v
end;

begin
end.

========================================

The solution, for this example, is to change the operator to receive a 'dword'. In the general case you will need to closely examine your code and ensure the the operator and operand sizes match.

program Solve;

var
v : Integer;

procedure Assembly;
asm
dd offset v
end;

begin
end.
=============== Paste from Help ===============

I think this is clear. Btw. have you tried to declare the vars. as Integer or Cardinal?

ive made a huge mistake, but its fixed. When ive compiled the program and click on my button a message pops up with EAccesViolation blabla cant read FFFFFFF or something like this. and now the line: edit3.text:=inttostr(Final); is highlighted.
to quit this thread could somebody send me a code which uses asm in delphi? thx a lot

Hello,

try my tutorial #44; (how to make a kg for ... using delphi + asm) or look at this:

*******************************************

var ECXINT, ESIINT, EAXINT : Cardinal;

asm
mov eax, eaxint
mov ecx, ecxint
mov esi, esiint
mov esi, eax
xor esi, ecx
test esi, $321952
jz @yes
add eax, eax
xor eax, $13218
shl ecx, $2
jmp @end
@yes:
shl eax, $4
shl ecx, $3
@end:
mov esiint, esi
mov eaxint, eax
mov ecxint, ecx
end;

*******************************************

I hope it helps you a bit
