Writing to Registry
-
Use BOOL IsUserAnAdmin(VOID); Perform writing to the registry only if this function returns true.

Sorry, but I see the question was not "very urgent", so I could ask the OP to take some time to let me know more of the error.

You're wrong:

Here is the code for IsUserAdmin
BOOL IsUserAdmin(VOID) /*++ Routine Description: This routine returns TRUE if the caller's process is a member of the Administrators local group. Caller is NOT expected to be impersonating anyone and is expected to be able to open its own process and process token. Arguments: None. Return Value: TRUE - Caller has Administrators local group. FALSE - Caller does not have Administrators local group. -- */ { BOOL b; SID_IDENTIFIER_AUTHORITY NtAuthority = SECURITY_NT_AUTHORITY; PSID AdministratorsGroup; b = AllocateAndInitializeSid( &NtAuthority, 2, SECURITY_BUILTIN_DOMAIN_RID, DOMAIN_ALIAS_RID_ADMINS, 0, 0, 0, 0, 0, 0, &AdministratorsGroup); if(b) { if (!CheckTokenMembership( NULL, AdministratorsGroup, &b)) { b = FALSE; } FreeSid(AdministratorsGroup); } -

The function information of IsUserAnAdmin() says - "Shell32.DLL version 5.0 or higher will be required" to make use of this call, which means earlier versions won't have this function exported at all. See here[^]. You'll need the latest SDK (or the SDK which is latest enough and has version 5.0 or higher of Shell32.DLL) to use this call.

Thanks.. But I written a user define function and written the above code.. I am getting a compilation error at CheckTokenMembership...
You should do the following: Header: Declared in Winbase.h; include Windows.h. Library: Use Advapi32.lib And look for Advapi32.dll. Check out MSDN for more details

Hi, My application writes into a particular location in Registry Eg. RegOpenKeyEx(HKEY_LOCAL_MACHINE, "Software\\Microsoft\\Windows\\CurrentVersion\\Run", 0, KEY_ALL_ACCESS, &h_Key); //Open a particular registry key //Write to that registry key. I need to restrict this activity to only Administrator.. Can I have a code snippet which allows this only for Administrator. Thanks. Venkat
