HRESULT QueryGetData(FORMATETC* pFormatetc);

Parameters

  • pFormatetc
    [in] Pointer to the FORMATETC structure defining the format, medium, and target device to use for the query.

Return Values

This method supports the standard return values E_INVALIDARG, E_UNEXPECTED, and E_OUTOFMEMORY.

The following table shows the additional return values for this method.

Value Description
S_OK Subsequent call to IDataObject::GetData would probably be successful.

Remarks

The client of a data object calls IDataObject::QueryGetData to determine whether passing the specified FORMATETC structure to a subsequent call to IDataObject::GetData is likely to be successful.

A successful return from this method does not necessarily ensure the success of the subsequent paste or drop operation.
