Handle leaks...Multithreading

Hello world,

I have problems to connect to an MySQL server via
ODBC Connector 3.51.23 and
Cherry City Software MySQL OLE DB Provider respectively.

There seems to be a handle leak if I open/close the db
connection from a worker thread. (Windows Task Manager shows
that for every database connection two more handles are
needed.)


I have attached a small test program which shows this
problem. (The database connections are created inside the
worker threads because the db user names and passwords
are constantly changing. In my "real" project it's possible
to have up to 10 parallel threads connecting to the
server.)


Please... help...


Best regards,
M. Wolters

unsigned int MyThread(void*)
{
std::cout << "Open... ";
CDatabase db;
db.OpenEx("DSN=MyDSN;UID=tilli;PWD=tilli", 0);
db.Close();
std::cout << "Close...\n";


return 0;



}


int main()
{
VERIFY(AfxWinInit(GetModuleHandle(0), 0, GetCommandLine(), 0));

for(int i=0; i<500; ++i)
{
std::cout << i << "\n";
AfxBeginThread(MyThread, 0);
Sleep(2500);
}


return 0;
