I need a way to check for an existing ODBC connection in the odbc data source administrator. All the research I have done indicates that the values are stored in either the INI file (not in XP) or the registry. I have determined that the ini file does not exist and I do not have access to the registry on this computer so my search skills are limited here. What I would like an easy way to see if the the connection named "tempconn" exists in the registry so that my code does not update the connection information when I use RegisterDatabase to establish the missing connection. This is all being done on an xp system (soon to be vista) inside a ms access database.
