Thanks. &nbsp;Now, to take it a little bit further. &nbsp;Is there a way to access a data member within that? &nbsp;For instance, if the CSerial class has a com port variable set to &quot;com2&quot;. &nbsp;Is there a way for me to get that data and place it on screen?

Yes, cast the pointer (CObject *) to CSerial *.

I'm setting up a CObArray to handle multiple data types. &nbsp;For instance I have a CLaser class derived from CObject and a CSerial class derived from CObject. &nbsp;Let's say I place both of these objects into a CObArray object, let's call it m_DeviceArray. &nbsp;Now I want to populate a list box on screen that will tell me what objects are in the array. &nbsp;How could I do this? &nbsp;How could I determine the object type on the fly? &nbsp;I don't know what the object at element 0 is...or the object at element 5 is...but I want to &quot;dump&quot; the object onto the screen.

CObArray with different data types

Kernel and system programming is the process of creating the software necessary for a computer or device to function and operate other programs. Some operating systems (such as Microsoft Windows) are proprietary, but others, such as the various Linux distributions, are open source.
