Hi, I got a strange ADO connection problem.<BR>The DSN was tested good after it&#039;s created. But when I used it in my code, I get the error messages saying:<BR><BR>Microsoft OLE DB Provider for ODBC Drivers error &#039;80004005&#039; <BR><BR>[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified <BR><BR>What&#039;s wrong? (the DB is SQL Server 7.0)<BR><BR>Thanks!
