RegConnectRegistry failure

I'm trying to change a registry key in a remote machine's HKEY_LOCAL_MACHINE branch using RegConnectRegistry(). Everything's set up okay - both machines are NT4 servers (SP3) and Administrator account is set up so that it has full control over both machine A and machine B and full access to both registries.

Here's my code:

LPTSTR lpMachineName;      // address of name of remote computer
      lpMachineName = "\\SEURD01WEB002";

      HKEY hKey; // predefined registry handle
      hKey = HKEY_LOCAL_MACHINE;

      PHKEY phkResult; // address of buffer for remote registry handle
      
      LONG diditwork;
      diditwork = 0;
      
      diditwork = RegConnectRegistry(
                              lpMachineName,
                              hKey,
                              phkResult
                                          );                                          

      if (diditwork != ERROR_SUCCESS)
      
            MessageBox ("Remote connection failed");


Can you guys see anything wrong with this code ? I've performed the connection manually using regedt32 and connecting to the machine name and the branch - it works fine...

...so please, save me from going crazy and tell me what I'm doing wrong ! Thanks a lot,

Derek

You aren't providing a place for the resultant HKEY to be stored, so you're passing the function an invalid pointer.
Try is this way:

LPTSTR lpMachineName; // address of name of remote computer
lpMachineName = "\\SEURD01WEB002";

HKEY hKey; // predefined registry handle
hKey = HKEY_LOCAL_MACHINE;

HKEY hkResult; // buffer for remote registry handle

LONG diditwork;
diditwork = 0;

diditwork = RegConnectRegistry(
lpMachineName,
hKey,
&hkResult
);

Thanks a lot - it works fine when I make the amendment you suggest. I'm an idiot - I was looking in the wrong place for the error !
