We recommend you do
A, you use adodc control first, then the control right select properties on the connection data operation, you select the "connection string" generated, and then select your engine, will generate connection string, you can operate it by adodc database,
Two, if you are to use references ado to connect to the database, then you will be automatically generated by the connection string, copy it out on your aa="" quotation marks inside the place to go, you can operate it by reference to ado database

I estimate that the problem is "Microsoft. Essentially. CE. The OLEDB. 3.5", if not the database engine
