Question 1:
When we create an COM object in a Process where does the memory of the COM objects get allocation?

Question 2:
Does the memory allocated to the COM object contributed to increase in Virtual memory of the process where it is instantiated.?

Question 3:
What is the relation between virtual memory of a process and private bytes of the process?

<code>TCHAR szDomain[] = 'DomainName'; // Change this to the domain that the user belongs to
TCHAR szUserName[] = 'Username'; // Change this to the desired user name
TCHAR szPassword[] = 'Password'; // Change this to th e user's pasword

HANDLE hUser = NULL;

BOOL bLoggedOn = LogonUser(szUserName, szDomain, szPassword, LOGON32_LOGON_NEW_CREDENTIALS, LOGON32_PROVIDER_WINNT50, &hUser);
if(!bLoggedOn) // Did it work ?
{
	DWORD dwErr = GetLastError(); // Process Error Here
	return;
}

	// Logon worked, so impersonate
if(!ImpersonateLoggedOnUser(hUser))
{
	DWORD dwErr = GetLastError(); // Process Error Here
	return;
}

	// Now you can call CreateInstanceHere

CoInitialize(0);

SHDocVw::IShellWindowsPtr spSHWinds;
HRESULT hr = spSHWinds.CreateInstance (__uuidof(SHDocVw::ShellWindows));

	// .. Do your work here
	// ...
	// ...
	// ...
	// ...
	// .. Make sure you are finished with spSHWinds before you call RevertToSelf();

	// Once done, you need to revery back to the LOCAL SYSTEM account
RevertToSelf();
