Re: Registering ActiveX control on Vista

Markus,

I haven't used this, so I am not sure. However, I am guessing that the
Registry Virtualization feature of User Account Control (UAC) may be messing
with you.

Are you logging in as a standard user?

You could also try logging in as an administrator *and* using the "Run As
Administrator" menu item. This is just to help identify what is going on, I
realise that's not how you need it to work in the long run.

Unfortunately I don't have the source of the control I want to use. Only
the
binaries.
Is overriding not possible any more in Windows Vista?

Change your registration code to not store data in HKCR,
but to store it in HKCU\Software\Classes instead. No need
to override registry keys then.

On WinXP it is possible to register an ActiveX contol on a per user
basis
with

FARPROC lpDllEntryPoint = GetProcAddress(hLib, "DllRegisterServer");
if (lpDllEntryPoint != NULL) {
HKEY hKeyCurrentUser;
RegOpenKeyEx(HKEY_CURRENT_USER, L"Software\\Classes", 0,
KEY_ALL_ACCESS,
&hKeyCurrentUser);
RegOverridePredefKey(HKEY_CLASSES_ROOT, hKeyCurrentUser);
RegCloseKey(hKeyCurrentUser);
(*lpDllEntryPoint)();
RegOverridePredefKey(HKEY_CLASSES_ROOT, HKEY_CLASSES_ROOT);
} else {

Registry keys are generated under HKCU so no administrator permissions
are
required. Under Vista (beta2) this does not work. No keys are
generated.
Does anyone know why and what to change?
Thanks
Markus
