I'm creating an MS Access database with:
Variant Catalog;
Variant Connection;
CoInitializeEx(NULL, COINIT_MULTITHREADED);
Catalog=Variant::CreateObject("ADOX.Catalog");
Catalog.Exec(Function("Create") << strConnectionString);
Connection = Catalog.Exec(PropertyGet("ActiveConnection"));
...
Connection.Exec(Function("Close"));
CoUninitialize();
Do I need to do anything special to close/release Catalog and
Connection?
What happens if Catalog and Connection go out of scope after the
CoUninitialize() call? Will this mean that an implicit close/release
happens after CoUninitialize(), and if so, will this cause problems?
