SYNOPSIS
HRESULT DispInvoke ( VOID* _this, ITypeInfo* ptinfo, DISPID dispidMember, USHORT wFlags, DISPPARAMS* pparams, VARIANT* pvarResult, EXCEPINFO* pexcepinfo, UINT* puArgErr )
PARAMS
_this [In] Object to call method on.
ptinfo [In] Object type info.
dispidMember [In] DISPID of the member (e.g. from GetIDsOfNames(3w)).
wFlags [In] Kind of method call (DISPATCH_ flags from "oaidl.h").

DISP_E_MEMBERNOTFOUND if the method does not exist. puArgErr is updated if a parameter error (see notes) occurs. Otherwise, returns the result of calling ITypeInfo_Invoke(3w).

- DISP_E_BADVARTYPE
E_INVALIDARG An argument was invalid
