ITransactionContext::CreateInstance method (comsvcs.h)

  • Article

Creates a COM object that can execute within the scope of the transaction that was initiated by the transaction context object.

Syntax

HRESULT CreateInstance(
  [in]  BSTR    pszProgId,
  [out] VARIANT *pObject
);

Parameters

[in] pszProgId

A reference to the ProgID of the type of object to be instantiated.

[out] pObject

A reference to the new object.

Return value

This method can return the standard return values E_INVALIDARG, E_OUTOFMEMORY, E_UNEXPECTED, E_FAIL, and S_OK.

Remarks

If the Microsoft Distributed Transaction Coordinator is not running and the object is transactional, the object is successfully created. However, method calls to that object will fail with CONTEXT_E_TMNOTAVAILABLE. Objects cannot recover from this condition and should be released.
