Good. You can also use CursorAdapter for this if you want.

Also note that from a security standpoint you may not want to code

cDSNLess = "driver={Microsoft ODBC para Oracle};server=myserver;uid=myuser;pwd=mypassword"

but

cDSNLess = "driver={Microsoft ODBC para Oracle};server="+m.cServer+";uid="+m.cUser+";pwd="+m.cPassword

where the variable sare read from an encrypted source and decrypted at runtime.
If you hard-code them in your connection string they are visible in the EXE.
