Error message -2147467259
272086Apr 29 2004 — edited May 6 2004A perfectly running application using VB6/Oracle/Crystal Report installed on multiple PC suddenly stopped working. To make it even worse, I don't know which installed application caused my app to stop working. During development I used, MDAC 2.5, Oracle ODBC 8.1.7. Created system DSN. Everything was running OK. Now I am getting error message Microsoft ODBC, specified DSN could not be found. I checked, TNSNames.ora, I checked Registry permission, all are well. Some culprit app is messing up my humble application. Can someone think of a possible cause that change ODBC not to work. It simply does not connect to Oracle DB. Stressed!!!!!!
