hi i am getting strange result ,same code working some time ,failing
most of the time..(2007).
internally getting error result like this
SCODE sc = m_lpDispatch->Invoke(dwDispID, IID_NULL, 0, wFlags,
&dispparams, pvarResult, &excepInfo, &nArgErr);

returning -2147352567
i have doubt
why this call failing only 2007 version.
why this call succeeding some times.
is this installation problem ?
any help really appreciable.
