I spent quite a bit of time today debugging an oracleconnection object. It would fail everytime the connection string property was set. This is what I would recieve in the error log:
Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e2111c0
Exception code: 0xe0434f4d
Fault offset: 0x0000d36f
I didn’t get to far Duck Duck Go’ing (or Googling) on this so I threw the assignment into an try catch block. I got an error “Connection string is not well formed”. Connectionstrings.com had a great section on Oracle so I copied/pasted it into my code changing the pertinent data. Same issue.
After trying several things I discovered that the connection strings for Oracle cannot have a trailing semi-colon.
Data Source=IDWorks;User Id=IDWorks;Password=idw;
Data Source=IDWorks;User Id=IDWorks;Password=idw
Hope this saved you some time!
