  • Article

3/26/2014

This method returns a GUID corresponding to the specified dwGuidKind.

The dwGuidKind parameter has several values defined. Additional flags can be defined at a later time and will be recognized by an IProvideClassInfo2 implementation.

Syntax

HRESULT GetGUID(
  DWORD dwGuidKind, 
  GUID* pGUID 
);

Parameters

  • dwGuidKind
    [in] GUID desired on return. This parameter takes a value from the GUIDKIND enumeration.
  • pGUID
    [out] Pointer to the caller's variable in which to store the GUID associated with dwGuidKind.

Return Value

The following table shows the return values for this method.

Value

Description

S_OK

The GUID was successfully returned in *pGUID.

E_POINTER

The address in pGUID is not valid (such as NULL).

E_UNEXPECTED

An unknown error occurred.

E_INVALIDARG

The dwGuidKind value does not correspond to a supported GUID kind.

Remarks

E_NOTIMPL is not a valid return code because it would be pointless to implement this interface without implementing this method.

E_INVALIDARG is not valid when dwGuidKind is GUIDKIND_DEFAULT_SOURCE_DISP_IID.

To determine whether the platform supports this interface, see Determining Supported COM APIs.
