Code:

void _declspec(naked) __stdcall FlyCave()
{
   __asm
   {
      push eax
           lea eax, [eax+34]
      mov eax, [dwFlyCaveOption]
      pop eax
           cmp dword ptr [eax+34],01 //this and line below are original code
           je 0x0040a167
           jmp FlyAddressReturn //go back to the address--a = in hex
   }
}


That gives me the error

Code:

inline assembler syntax error in 'first operand'; found ')'


at the instruction "jmp FlyAddressReturn"

Help?

Code:
jmp [FlyAddressReturn]


Also, __stdcall isn't needed.

Thanks, again!

I just saw _stdcall in Wicc's dll tutorial, so I'm gonna leave it there for safe-keeping.

Edit

Same error.. =(

Compiles fine using VC05 with no warnings at /W4. I don't know what the problem could be with yours. Confused

I'ma go screw around with the settings, and see if that helps at all.

Edit:

-.-;

I'm using VS 2005 Professional, with the settings that Wicc mentioned in his tutorial, and I have no idea what's wrong.

This is solved as far as I know, helped Sam with it over MSN, he had declared FlyAddressReturn as a define and not a DWORD so the inline was catching part of the macro and not what he was intending it to be. Mad

What he had it originally as:

Code:
#define FlyAddressReturn (FlyAddress + 0x0a)


(Incase people were wondering.

I'm assuming you're trying to jump to a constant as opposed to the value of a variable which holds the jump address.

Just try the following:

Code:
DWORD dwJMP = 0x00400000;

_asm jmp [dwJMP]


Yeah, I was using a macro for it, but Wicc helped me fix it; thanks though.
