inline asm, jumping.

inline asm code:

Code:

__asm{
	cmp eax,ecx
	jbe 0x12345678
}

becomes

Code:

0034159C  cmp eax,ecx 
0034159E  jbe main+34h (3415A4h)

anyone know how to make it jump to specified address (0x12345678)?
thanks.

ohaiidesu i incorrectly read the question

Code:

mov eax, 0x12345678
jmp eax

Code:

push 0x12345678
ret

Code:

DWORD dwAddress = 0x12345678
/**************************/

jmp dword ptr ds:[dwAddress]

my bad, regular jmp work. other jump instruction jumps to wrong place (ja,jna,je,jne,jb,jba, you name it), jbe in my case. guess i'll have to modify it with olly after compiled.
or it might just be vc++ 2008?
thanks.

They are relative jumps.
Just add a normal jmp to where you want to go below it and jump over it with ja

fixed it with:

Code:

			cmp eax,ecx
			jbe GG
			jmp ERR
GG:
			jmp OKK

thanks for your help.
