hi, takx for your reply

i found some examples but i can't adapt to my needs...

this is one:
mov cbData, SIZEOF Data
invoke SHSetValue,HKEY_CURRENT_USER,OFFSET SubKey,offset value,REG_SZ,offset Data,cbData

when i assemble i get errors...
i don't know what i have to change...

remember when you start asm coding, everything is a chalenge...
something basic for you is dificult for me...

and the only way is get some help from people like you...

You really should check Iczelion's tutorials. Those are a REALLY pice of work. About thet function and all others:
- check if the include file and lib file can be found by ml and LINK
- check if all those variables/constants are declared
- !! READ THE ERROR!! (and share it, no one can know what  is happening in there if you don't tell us)

And RADAsm is a great IDE for this job.

I've just post my first app and the full source code. Search here for "My educational system" or "blind crypt", and you'll find both there.

yo...
hi have this code:
.386
.model flat,stdcall
option casemap:none

include      windows.inc
include      user32.inc
include      kernel32.inc
includelib   user32.lib
includelib   kernel32.lib

DlgProc      proto      :DWORD,:DWORD,:DWORD,:DWORD

.data

.data?
hInstance   HINSTANCE   ? 
hTarget      HINSTANCE   ?
RBuffer      dd      ?
BytesRead   db      ?
BytesWritten   db      ?


.const
IDD_APP   equ      1001
IDC_REG   equ     1002


.code
start:
    invoke GetModuleHandle, NULL
    mov    hInstance,eax
    invoke DialogBoxParam, hInstance, IDD_PATCH, NULL, addr DlgProc, NULL
    invoke ExitProcess,eax
   
DlgProc proc hWnd:HWND, uMsg:UINT, wParam:WPARAM, lParam:LPARAM
   .if uMsg==WM_INITDIALOG
      invoke SendMessage,hWnd,WM_SETICON,1,eax
   .elseif uMsg==WM_COMMAND
      mov   eax,wParam
      .if eax==IDC_REG   
         mov cbData, SIZEOF Data
            invoke SHSetValue,HKEY_CURRENT_USER,OFFSET SubKey,offset value,REG_SZ,offset Data,cbData
      .endif
   .elseif   uMsg==WM_CLOSE
      invoke   EndDialog,hWnd,0
   .endif
    xor   eax,eax
    ret
DlgProc endp

end start


----------------------------------------------------------------------------------------------

can you mke the declares, just for i understand?
the IDC_REG is the button to start the action
supose you have to create:
HKCU\Software\Xpto\XptoInfo\Name\myname

just to learn...

If you want quick-fix wrappers to get the work done, you could check this:
http://www.masm32.com/board/index.php?topic=5735.0

The Registry_Write... functions.

You can examine the source and see the steps that go in actually setting a value to a registry key (Opening a key, checking, setting value, checking, closing... etc)

Cheers,

            invoke SHSetValue,HKEY_CURRENT_USER,OFFSET SubKey,offset value,REG_SZ,offset Data,cbData

First of all, you have not work through very much code yet.  Keep reading and you will answer your own questions.

AFAIK for this problem, you need to read up on the API and include the supports files ( Which are missing from your code. ) that go with it.

PS:  That you will maybe get you past getting an exe file produced, but in no way means it will work.  Still more debugging ahead.
