DispGetIDsOfNames function (oleauto.h)

  • Article

Low-level helper for Invoke that provides machine independence for customized Invoke.

Syntax

HRESULT DispGetIDsOfNames(
        ITypeInfo *ptinfo,
  [in]  LPOLESTR  *rgszNames,
        UINT      cNames,
  [out] DISPID    *rgdispid
);

Parameters

ptinfo

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.

[in] rgszNames

An 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

The number of elements in rgszNames.

[out] rgdispid

An array of DISPIDs to be filled in by this function. The first ID corresponds to the method name. Subsequent IDs are interpreted as parameters to the method.

Return value
