I used the following code to imperonate the normal user. It is returning true. But when i am writing into the reigstry it is returning the error code 5(access denied). is my code right?
bool ImpersonateUser::Logon(char* userName, char* domain, char* password)
{
if(init_)
Logoff();
if(userName == NULL) // Must at least specify a username
{
errorCode_ = ERROR_BAD_ARGUMENTS;
return false;
}
// Attempt to log on as that user
BOOL bLoggedOn = FALSE;
if(domain == NULL ) // Domain name was specified
bLoggedOn = LogonUser(userName, domain, password, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, &userToken_);
else
bLoggedOn = LogonUser(userName, domain, password, LOGON32_LOGON_INTERACTIVE,/*LOGON32_LOGON_NEW_CREDENTIALS*/LOGON32_PROVIDER_WINNT50, &userToken_);
if(!bLoggedOn)
{
errorCode_ = GetLastError();
return false;
}
// Now impersonate them
if(!ImpersonateLoggedOnUser(userToken_))
{
errorCode_ = GetLastError();
return false;
}
init_ = true;
return true;
}
//it is returning true
LONG lRet = ::RegOpenKeyEx(HKEY_LOCAL_MACHINE,_T("Software\\Wonderware\\InTouch\\Installation"),0,KEY_SET_VALUE,&hKey);
lRet ::RegSetValueEx(hKey,"InstallPath",0,REG_SZ,(BYTE*)("C:\\Windows"),dwSize);
//it is retunging 5(access denied)
is something wrong with impersonation code
Thanks |
