HRESULT DispGetIDsOfNames(
ITypeInfo* ptinfo,
OLECHAR FAR* FAR* rgszNames,
unsigned int cNames,
DISPID FAR* rgdispid
);
Uses type information to convert a set of names to DISPIDs. This is the recommended implementation of IDispatch::GetIDsOfNames.
The return value obtained from the returned HRESULT is one of the following:
Return value | Meaning |
---|---|
S_OK | The interface is supported. |
E_INVALIDARG | One of the arguments is invalid. |
DISP_E_UNKNOWNNAME | One or more of the given names were not known. The returned array of DISPIDs contains DISPID_UNKNOWN for each entry that corresponds to an unknown name. |
Other return codes | Any of the ITypeInfo::Invoke errors can also be returned. |
This code from the Lines sample file Points.cpp implements the member function GetIDsOfNames for the CPoints class using DispGetIDsOfNames.
