        'Create the key
        If RegCreateKeyEx(m_Key, KeyPath, 0, "", _
            REG_OPTION_NON_VOLATILE, KEY_ALL_ACCESS, 0&, KeyCreate, Dispose) <> ERROR_SUCCESS Then
            'Create key faild
            CreateKey = 0
        Else
            'Good result
            CreateKey = 1
        End If
        
        'Close the key
        Call CloseRegKey(KeyCreate)
        'Clear up
        KeyPath = vbNullString

Thanks for anyone at looking at this, but I now fixed the problum.
I fixed it by having to set permissions on the Reg key in regedit and giving full control to the path.
Thanks agian.

It may be useful for others if you told how you solved the problem in case someone finds this thread upon searching.

You need to elevate your process to run under Administrator permissions.

Isn't there an automatic way to achieve this through VB, rather than manually opening regedit and changing the permissions on a key ?

Yes, you can use registry APIs to set security permissions on it.

Note the lpSecurityDescriptor element of the type.

Hello, guys!
I tried to use RegCreateKeyEx to create "HKEY_CURRENT_USER" "Software\Microsoft\Windows\CurrentVersion\Policies\Explorer" key. But Vista don't allow it and I get error. I don't get an elevation prompt either.
Why? I'm an admin. HKEY_CURRENT_USER is for user purposes instead of HKEY_LOCAL_MACHINE.

Is there the answer to this question?

Please can anyone write a simple code by using it?

I don't have vista to test it on, but try setting dwOptions to REG_OPTION_BACKUP_RESTORE and also lpSecurityDescriptor to SECURITY_ATTRIBUTES

ie:

Dim lngRetval     As Long
Dim lngKeyHandle  As Long
Dim typSecAtt     As SECURITY_ATTRIBUTES
 
typSecAtt.nLength = Len(typSecAtt)
typSecAtt.lpSecurityDescriptor = 0&
typSecAtt.bInheritHandle = False
 
RegCreateKeyEx(lngHKey, strSubKey, REG_OPTION_RESERVED, 0&, REG_OPTION_BACKUP_RESTORE, KEY_CREATE_SUB_KEY, typSecAtt, lngKeyHandle, lngRetval)

EDIT:- You will also have to call AdjustTokenPrivileges with "SeRestorePrivilege" and "SeBackupPrivilege" before trying the above code.
