DispGetIDsOfNames

Windows Mobile 6.5
A version of this page is also available for
4/8/2010

This function uses type information to convert a set of names to DISPIDs.


HRESULT DispGetIDsOfNames(
  ItypeInfo* ptinfo, 
  OLECHAR FAR* FAR* rgszNames, 
  unsigned int cNames, 
  DISPID FAR* rgdispid 
);

ptinfo

[in] Pointer to the type information for an interface. This type information is specific to one interface and language code, so it is not necessary to pass an interface identifier (IID) or LCID to this function.

rgszNames

[in] Array of name strings that can be the same array passed to DispInvoke in the DISPPARAMS structure.

If cNames is greater than 1, the first name is interpreted as a method name and subsequent names are interpreted as parameters to that method.

cNames

[in] Number of elements in rgszNames.

rgdispid

[out] Pointer to an array of DISPIDs to be filled in by this function.

The first identifier corresponds to the method name. Subsequent identifiers are interpreted as parameters to the method.

Returns the HRESULT values shown in the following table.

Value Description

S_OK

The interface is supported.

E_INVALIDARG

An argument is invalid.

DISP_E_UNKNOWNNAME

One or more 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 ITypeInfo::Invoke error can be returned.

Passing invalid (and under some circumstances NULL) pointers to this function causes an unexpected termination of the application.

This code from the Lines sample file Points.cpp implements the member function GetIDsOfNames for the CPoints class using DispGetIDsOfNames.

STDMETHODIMP
CPoints::GetIDsOfNames(
  REFIID riid,
  char FAR* FAR* rgszNames,
  UINT cNames,
  LCID lcid,
  DISPID FAR* rgdispid)
{
  return DispGetIDsOfNames(m_ptinfo, rgszNames, cNames, rgdispid);
}
