IMessenger3->InstantMessage() by RaceProUK on 06-25-2005 at 07:11 PM
I call this method witha correctly set-up 'contact' argument, and a valid pointer to receive the IMessengerConversationWnd* (as IDispatch*, so no typecasting). So why do I always get 'We are unable to start a conversation.'?
Update: A bit of testing shows that, despite using an e-mail address that differs from mine, I get 'E_FAIL', meaning I called it against myself?

To make things certain: How do you set-up the vContact argument? 
RE: IMessenger3->InstantMessage() by RaceProUK on 06-26-2005 at 01:07 PM
code:where 'param' is a WCHAR*.
VariantInit(&contact);
contact.vt = VT_BSTR;
contact.bstrVal = (BSTR)param;
Edit: Never mind - it was a threading issue.
