CreateItem change for Outlook 2007? E_NOINTERFACE for returned objects. msoliver <michaelsoliver[ at ]gmail.com> 6/2/2007 5:01:06 PM I'm writing a simple C++/ATL program that is interacting w/ the Outlook object model. There seems to be some odd change to Application.CreateItem for Outlook 2007. Here are my simple lines of code: Outlook::_ApplicationPtr spApplication; Outlook::_MailItemPtr spMailItem; HRESULT hr = spApplication.CreateInstance(__uuidof(Outlook::Application)); if (FAILED(hr)) return; spMailItem = spApplication->CreateItem(Outlook::olMailItem); spMailItem is NULL after this code executes. Stepping into CreateItem, I see that it is returning a IDispatch*, but then when the QueryInterface occurs for the _MailItem* interface, the COM error code is: E_NOINTERFACE. This seems to be the case for all of the different types of Outlook items, not just mail items. What changed? What object is being returned by CreateItem? I've looked all over the net and MSDN and found no info - am stumped.

Does it make any difference if Outlook is already running when your code is executed?

Same result if Outlook is running. CreateItem is returning an IDispatch object, just can't seem to QueryInterface on it to get the right item... Any ideas? Thx, - Mike

Re: CreateItem change for Outlook 2007? E_NOINTERFACE for returned objects. "Dmitry Streblechenko" <dmitry[ at ]dimastr.com> 6/7/2007 11:29:42 PM Can you check that the GUID is right?? Or hardcode QI to use {00063034-0000-0000-C000-000000000046}?
