    [in] LPCWSTR pwzArgument,  
    [out] DWORD *pReturnValue

Return Value

HRESULT Description
S_OK ExecuteInDefaultAppDomain 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. If a method returns E_FAIL, the CRL is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.


The invoked method must have the following signature:

static int pwzMethodName (String pwzArgument)  

where pwzMethodName represents the name of the invoked method, and pwzArgument represents the string value passed as a parameter to that method. If the HRESULT value is set to S_OK, pReturnValue is set to the integer value returned by the invoked method. Otherwise, pReturnValue is not set.
