Hello,
[Quoted] I am attempting to run the Oracle OO4O sample with a slight modification and I get an Access Violation on the OShutdown() call:
First-chance exception in Tony3.exe (ORACLM32.DLL): 0xC0000005: Access Violation.
I tried uninstalling OO4O and installing the latest files for the OTN site OO4O version 8.1.6.3.1.3 and it did not help.
Thanks,
Tony
Below is the code:
#include<stdio.h> #include<stdlib.h> #include "oracl.h"
int main()
{
// Initialize the C++ Class Library before use.
// Usually initialization is done at the beginning of the program.
OStartup();
// Construct a database, obtaining a database connection:
ODatabase odb("RD2T", "scott", "tiger");
// The Odatabase object (odb) allows you to connect to a database
// ("ExampleDB") along with other connection information, and so sets
// you up to execute SQL statements.
// Construct a dynaset, obtaining the data records:
ODynaset odyn(odb, "select * from emp");
// The dynaset (odyn) corresponds to a cursor. It gives you access
// to the rows that are obtained by an SQL select statement.
// Create a variable to contain salary information:
double salary;
// Now look at each record:
while (!odyn.IsEOF())
// This method (IsEOF) returns TRUE when you have moved through the
// entire set.
{
// Get the salary for the current record: odyn.GetFieldValue("sal", &salary);
printf("Salary = %f\n", salary);
// This overloaded method (GetFieldValue) obtains the value of
// a field in the current record of the dynaset.
// Do something with the salary:
//salary = salary + 1;
// This method (Analyze) is created by the user.
// Go to the next record (perhaps moving past the last record):
odyn.MoveNext();
// This overloaded method (MoveNext) changes the current record
// to be the next record in the dynaset's result set.
}
// Uninitialize the C++ Class Library when you are finished with it.
// Usually uninitialization is done at the end of the program.
OShutdown();
return 0;
