RegEnumKeyEx

[mariø]

Hello,
trying to get all the keys and values of a specific registry entry.
this code I have wrote returns ERROR_NO_MORE_ITEMS in the first call to RegEnumKeyEx
and i have items in this key...

Code Select Expand



sKey db "Software\Microsoft\Windows\CurrentVersion\Run",0


DisplayRegistry proc
LOCAL hKey:DWORD
LOCAL index:DWORD
LOCAL keyName[256]:BYTE
LOCAL keyValue[256]:BYTE
LOCAL buffersize:DWORD
mov index,0

Invoke RegOpenKeyEx,HKEY_CURRENT_USER, ADDR sKey, NULL, KEY_READ,ADDR hKey
.If (eax== ERROR_SUCCESS )
  .If (hKey != NULL)
    mov buffersize,sizeof keyName
    Do:
    int 3
invoke RegEnumKeyEx,hKey, index, ADDR keyName, ADDR buffersize, NULL, NULL, NULL, NULL
             .if (eax!=ERROR_NO_MORE_ITEMS)
                mov buffersize,sizeof keyName
          invoke RegQueryValueEx, hKey, ADDR keyName, NULL, ADDR rtype,ADDR keyValue,ADDR buffersize
        invoke MessageBox, NULL,addr keyName, addr keyValue, MB_OK
                  inc index
                jmp Do
        .endif
           invoke RegCloseKey, hKey
      .EndIf   
.EndIf

Ret
DisplayRegistry EndP

Mario,

That is the correct result back from that registry key because there shouldn't (and at least on the three machines I checked here) there aren't any subkeys.

My first question is this:  Are you really trying to find subkeys for enumerate the values in that key? If you are trying to enumerate values, look at RegEnumValue API.

I need to enum the values, but I need the value Name too.
Im wrong, because I'm thinking that RegEnumKeyEx returns the value name...
Thanks.

Mario,

RegEnumValue will give you the field name and the data vailue for all field/value pairs in a specified key.

So if you are trying to get everything that is listed in the "Run" key, this is the API call you would be using to enumerate them.

RegEnumKeyEx will give you a list of subkeys from the specified key (basic example of this is a tree view style liisting).
