How to auto logon windowsxp in winlogon notification package?

[Guest dawnwind]

Hi all

I have write a winlogon notification package for WindowsXP. It will show a

dialog in Startup event. And I want login automatically, how to do this?

I have written the flowing code in startup callbak

 

LogonUser( TEXT("Administrator"),NULL,TEXT("111"),

LOGON32_LOGON_INTERACTIVE,LOGON32_PROVIDER_DEFAULT,&hToken)

 

HDESK hDesk = ::CreateDesktop( _T("WinSta0\\Default"), NULL, NULL,

DF_ALLOWOTHERACCOUNTHOOK, GENERIC_ALL, NULL )

 

SwitchDesktop( hDesk )

bRet = ::CreateProcessAsUser( hToken,

 

NULL, _T("explorer.exe"), NULL, NULL, FALSE, 0, NULL, NULL, &si, &pi )

 

 

 

It will get BSOD at CreateProcessAsUser. Is there some thing I missed? How

can I do this?

 

 

 

Thanks very much.
