I don't know why it doesn't work
please can anybody help me about this code ?

Code:

 format PE GUI 4.0
entry start

include 'd:\fasm\include\win32a.inc'


 struc dw [arg] {
 common
 . dw arg
 sizeof.#. = $-.
}


    struct RASENTRYNAME

        dwSize dd ?
        szEntryName db 260 dup(?)
        dwFlags dd ?
        szPhonebookPath db 264 dup(?)

    ends




   struct RASDIALPARAMS

        dwSize dd ?
        szEntryName db 101h dup(?)
        szPhoneNumber db 81h dup(?)
        szCallbackNumber db 81h dup(?)

Your question is too generalized. What doesn't work?

Editor? Compiler? API ? This website? You?

typedef

i m trying to translate that Autodial internet connection code

i think after this code

Code:

invoke lstrcpy,rpp.szEntryName,RASENTRYNAME.szEntryName[EAX]
invoke RasGetEntryDialParams,0,rpp, fPass

eax value is not zero so it is Failed

Quote:

Code:

invoke lstrcpy,rpp.szEntryName,RASENTRYNAME.szEntryName[EAX]

What is EAX doing here? Is this compiling in FASM?

Your're better off translating from C to FASM syntax not from MASM to FASM.

Code:

invoke lstrcpy,rpp.szEntryName,RASENTRYNAME.szEntryName[EAX]
invoke RasGetEntryDialParams,0,rpp, fPass
cmp eax, 0 ; ====== > this eax
jne RetFail
mov [hConn], 0

in MSDN

DWORD RasGetEntryDialParams(

LPTSTR lpszPhonebook, // pointer to the full path and filename of the phone-book file
LPRASDIALPARAMS lprasdialparams, // pointer to a structure that receives the connection parameters
LPBOOL lpfPassword // indicates whether the user's password was retrieved
);

Return Values

If the function succeeds, the return value is zero.

yes C code looks simple
maybe somebody can translate it from C to Fasm who knows C language

I just tried to rewrite the code from http://blog.csdn.net/fornormandy/article/details/70039 to FASM. It does execute but after a bit of debugging I noticed I was getting error 632 (ERROR_INVALID_SIZE). Hmm, I did a Google search, then bam!. It turns out it's not an easy task. I was going to write the whole code for you but since I know it can be fixed, I'll leave it to you. The first call worked on my computer and it did return my list of VPN names.

So here, (define the structure in the code attached then use GetVersionEx to determine which structure to use)

Link 1 (solution): http://www.powerbasic.com/support/pbforums/showthread.php?t=14367

TIP: Use ras.h (Comes with your Windows SDK) to create the structures in FASM like I was doing then use GetVersionEx API to determine which structure to use.

Structure definitions: (Please read these thoroughly)

Rules For Programming On Windows:

1. Read the documentation
2. USE A FUCKING DEBUGGER. Actually on any platform. It's the closest thing to the truth.

If I missed anything you'll be able to figure it out. I did you a huge favor here pal. Evil or Very Mad

Thanks for helping typedef i will read those documentations
and i will try to translate it from C as I know

Masm32 code is confusing

I translated it from C to Fasm. Anyway it works now
