Sounds interesting. Sorry I have never tried to dynamically load classes in RT, I have enough trouble these days just getting normal code to deploy without stupid un-explainable errors in LabVIEW. For some reason my RT VM is not cooperating and I cannot copy any files across to test. Have you tried to load a very simple class? I presume you have some kind of HAL with inheritance? Maybe the error is because it is missing some dependencies? (I know error 7 is missing file though, as you mentioned). Have you tried loading the class with the 0x10 option? -

I'm coding some pretty complex software. That's why I choose the object-oriented approach. And the factory pattern will help to achieve the flexibility that i need. -
I have never actually tried to use the factory pattern on a cRIO. So much trouble getting it to work properly just under Windows I have never been brave enough. Do you absolutely have to do runtime instantiation using names? Have you tried a static VI reference?

That's a standard technique I use all the time to prevent unwanted code coupling. In fact I almost always do it if I have reason to pass the address of an actor. I use either "Send" or "Actor" parent classes; there is no reason to use "Actor type 2". With the Send class (the grandparent of all address classes) one also has the option of passing a TCP Messenger, allowing you to run C or D on a different machine. -

Sorry, I saved my classes at /home/lvuser/natinst/LabVIEW Data/Host_Class -
I am a bit confused. You said you saved the classes to: /home/lvuser/natinst/bin/Host_Class but then you tried to load them from /home/lvuser/natinst/LabVIEW Data/Host_Class/Accelerometer/Accelerometer.lvclass These directories are different...
