IHostSecurityManager::ImpersonateLoggedOnUser Method

  • Article

Requests that code be executed using the credentials of the current user identity.

HRESULT ImpersonateLoggedOnUser (
    [in] HANDLE hToken
);

Parameters

  • hToken
    [in] A token representing the credentials of the user to be impersonated.

Return Value

HRESULT Description

S_OK

ImpersonateLoggedOnUser returned successfully.

HOST_E_CLRNOTAVAILABLE

The common language runtime (CLR) has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully.

HOST_E_TIMEOUT

The call timed out.

HOST_E_NOT_OWNER

The caller does not own the lock.

HOST_E_ABANDONED

An event was canceled while a blocked thread or fiber was waiting on it.

E_FAIL

An unknown catastrophic failure occurred. When a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.

Remarks

Call LogonUser or a related Win32 function to get a handle to the credentials of the current user identity.

The HANDLE type is not COM-compliant, that is, its size is specific to an operating system, and it requires custom marshaling. Thus, this token is for use only within the process, between the CLR and the host.

Requirements

Platforms: Windows 2000, Windows XP, Windows Server 2003 family

Header: MSCorEE.idl

Library: Included as a resource in MSCorEE.dll

.NET Framework Version: 2.0
