The following pseudo-code shows how to call a function (GetComApp.m, described in NET.disableAutoRelease) which returns a COM object. The object, mainObj of type NetDocTest.MyClass, has a property, MyApp. Call GetComApp to get a COM object, and use its readData method.

mainObj = NetDocTest.MyClass;
GetComApp(mainObj);
app = mainObj.MyApp;
app.readData('hello');
% Unlock the COM object
NET.enableAutoRelease(mainObj.MyApp);
