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

Syntax

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

Parameters

• 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.

Return Value

Returns the HRESULT values shown in the following table.

Remarks

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

Example

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);
}
