ADODB CreateInstance returns ERROR_NO_TOKEN 1008

I am trying to access a SQL database on a Windows 2003 server (although I would be doing this on 2000 servers as well), but when I try to call CreateInstance with a _ConnectionPtr object, it fails with "ERROR_NO_TOKEN: 1008: An attempt was made to reference a token that does not exist." The code could not be simpler:

hResult = m_lpADOConnect.CreateInstance("ADODB.Connection");

Is there some other initialization I need to do before making this call? Thanks for all help and advice.

Solution

  • I figured it out. I was forgetting to call CoInitialize(NULL); beforehand.
